MERGER PROPOSED—YOUR VOTE IS VERY IMPORTANT

To the Shareholders of Integrys Energy Group, Inc.:

        You are cordially invited to attend a special meeting of the shareholders of Integrys Energy Group, Inc., which we refer to as Integrys, to be held on November 21, 2014 at 10:00 a.m. central time, in the Aon Building at 200 E. Randolph Street, South Lobby/Parking Level 1, Chicago, Illinois 60601. As previously announced, the boards of directors of Wisconsin Energy Corporation, which we refer to as Wisconsin Energy, and Integrys, have approved an agreement and plan of merger, dated as of June 22, 2014, as it may be amended from time to time, which we refer to as the merger agreement, that will result in Integrys becoming a wholly-owned subsidiary of Wisconsin Energy. Under the terms of the merger agreement, Integrys shareholders will have the right to receive 1.128 shares of Wisconsin Energy common stock, par value $0.01 per share, plus $18.58 in cash, per each share of Integrys common stock, par value $1.00 per share, outstanding at the time of the merger. Based on the closing price of Wisconsin Energy common stock on June 20, 2014, the last trading day before the public announcement of the merger, the aggregate value of the foregoing stock and cash merger consideration to be received by Integrys shareholders was approximately $5.8 billion. Based on the closing price of Integrys common stock on June 20, 2014, Integrys shareholders will receive a 17.3 percent premium to Integrys' closing price on June 20, 2014, and a 22.8 percent premium to the volume-weighted average share price over the 30 trading days ending on June 20, 2014. Upon closing of the transaction, Wisconsin Energy stockholders and Integrys shareholders will own approximately 72 percent and 28 percent, respectively, of the combined company. Subject to approval by Wisconsin Energy's shareholders of a name change proposal, as described in this joint proxy/prospectus, the combined company will be named "WEC Energy Group, Inc." The common stock of Wisconsin Energy and Integrys are listed on the New York Stock Exchange under the symbols "WEC" and "TEG," respectively. We urge you to obtain current market quotations for the shares of Wisconsin Energy and Integrys common stock.

        After careful consideration, our board of directors has determined that the transactions contemplated by the merger agreement are in the best interests of Integrys and its shareholders, and our board of directors has approved the merger agreement. In order to complete the merger, the shareholders of Integrys must approve the merger agreement. At the special meeting of shareholders of Integrys, you will be asked to vote on a proposal with respect to the adoption of the merger agreement, a copy of which is attached as Annex A to this joint proxy statement/prospectus, which we refer to as the Merger proposal, a proposal with respect to an advisory vote on the merger-related compensation arrangements of Integrys' named executive officers, which we refer to as the Merger Related-Compensation proposal, and a proposal to adjourn the meeting if necessary to permit further solicitation of proxies in the event that there are not sufficient votes at the time of the special meeting to approve the Merger proposal, which we refer to as the Integrys Meeting Adjournment proposal. Our board of directors unanimously recommends that you vote FOR the Merger proposal, FOR the Merger-Related Compensation proposal and FOR the Integrys Meeting Adjournment proposal.

        Your vote is very important, regardless of the number of shares you own. We cannot complete the merger unless the Merger proposal is approved by our shareholders at the special meeting. Only shareholders who owned shares of Integrys common stock at the close of business on October 13, 2014 will be entitled to vote at the special meeting. Whether or not you plan to be present at the special meeting, please complete, sign, date and return your proxy card in the enclosed envelope, or authorize the individuals named on your proxy card to vote your shares by calling the toll-free telephone number or by using the internet as described in the instructions included with your proxy card. If you hold your shares in "street name," you should instruct your broker how to vote your shares in accordance with your voting instruction form. This joint proxy statement/prospectus explains the merger, the merger agreement and the transactions contemplated thereby and provides specific information concerning the special meeting. Please review this document carefully. You should carefully consider, before voting, the matters discussed under the heading "Risk Factors" beginning on page 32 of this joint proxy statement/prospectus.

        On behalf of our board of directors, I thank you for your support and appreciate your consideration of this matter.

    Very truly yours,

QUESTIONS AND ANSWERS ABOUT THE SPECIAL MEETINGS

        The following questions and answers briefly address some commonly asked questions about the Wisconsin Energy and Integrys special meetings and the merger described in this joint proxy statement/prospectus. They may not include all the information that is important to stockholders of Wisconsin Energy and shareholders of Integrys. Stockholders of Wisconsin Energy and shareholders of Integrys should carefully read this entire joint proxy statement/prospectus, including the annexes and the other documents referred to herein. Unless otherwise specified, all references in this joint proxy statement/prospectus to:

Q:
Why am I receiving this joint proxy statement/prospectus?

A:
Wisconsin Energy and Integrys are sending this joint proxy statement/prospectus and the materials included herein to their stockholders and shareholders, respectively, to help them decide how to vote their shares of Wisconsin Energy common stock or Integrys common stock, as the case may be, with respect to the merger and other matters to be considered at their respective special meetings.


The merger cannot be completed unless Wisconsin Energy stockholders approve the issuance of Wisconsin Energy common stock in the merger, and Integrys shareholders approve the merger agreement. Each of Wisconsin Energy and Integrys is holding a special meeting of its stockholders and shareholders, as the case may be, to vote on the proposals necessary to complete the merger. Information about these special meetings, the merger and the other business to be considered by stockholders at each of the special meetings is contained in this joint proxy statement/prospectus.


This joint proxy statement/prospectus constitutes both a joint proxy statement of Wisconsin Energy and Integrys and a prospectus of Wisconsin Energy. It is a joint proxy statement because each of the boards of directors of Wisconsin Energy and Integrys are soliciting proxies from their respective shareholders. It is a prospectus because Wisconsin Energy will issue shares of its common stock in exchange for outstanding shares of Integrys common stock in the merger.

Q:
What will happen in the proposed merger?

A:
Wisconsin Energy and Integrys have entered into the merger agreement. A copy of the merger agreement is attached as Annex A to this joint proxy statement/prospectus. The merger agreement contains the terms and conditions of the proposed business combination of Wisconsin Energy and Integrys. Pursuant to the merger agreement, merger sub will merge with and into Integrys, with

Table of Contents

Q:
What will Integrys shareholders receive in the merger?

A:
In the merger, for each share of Integrys common stock, Integrys shareholders will receive 1.128 shares of Wisconsin Energy common stock, which we refer to as the stock consideration, and $18.58 in cash, which we refer to as the cash consideration. The stock consideration and cash consideration are collectively referred to as the merger consideration. Based on the closing price of Wisconsin Energy common stock on June 20, 2014, the last trading day before the public announcement of the merger, the aggregate value of the merger consideration was approximately $5.8 billion. Integrys shareholders will also receive cash in lieu of fractional shares. The merger consideration is fixed and will not be adjusted to reflect changes in the stock price of either company before the merger is completed. Wisconsin Energy stockholders will continue to own their existing shares of Wisconsin Energy common stock and will not receive any merger consideration.

Q:
When do Integrys and Wisconsin Energy expect to complete the merger?

A:
Wisconsin Energy and Integrys are working to complete the merger as soon as practicable. We currently expect that the merger will be completed in the second half of 2015. Neither Wisconsin Energy nor Integrys can predict, however, the actual date on which the merger will be completed because it is subject to conditions beyond each company's control, including the receipt of Wisconsin Energy stockholder approval and Integrys shareholder approval, and federal and state regulatory approvals. For additional information on the regulatory approvals required to complete the merger, please see "The Merger—Regulatory Approvals Required for the Merger" beginning on page 101. For additional information on the conditions to the completion of the merger, please see "The Merger Agreement—Conditions to Completion of the Merger" beginning on page 117.

Q:
What am I being asked to vote on and why is this approval necessary?

A:
Wisconsin Energy stockholders are being asked to vote on the following proposals:

1.
to approve the issuance of common stock of Wisconsin Energy as contemplated by the merger agreement, as it may be amended from time to time, which we refer to as the Share Issuance proposal;

2.
to approve an amendment to Wisconsin Energy's restated articles of incorporation to change the name of Wisconsin Energy from "Wisconsin Energy Corporation" to "WEC Energy Group, Inc.", which we refer to as the Name Change proposal; and

3.
to adjourn the Wisconsin Energy special meeting, if necessary or appropriate, to permit further solicitation of proxies in the event that there are not sufficient votes at the time of the special meeting to approve the Share Issuance proposal, which we refer to as the Wisconsin Energy Meeting Adjournment proposal.


Only the approval of the Share Issuance proposal is required to complete the merger. The Share Issuance proposal is not conditioned on the approval of the Name Change proposal. The Name Change proposal is conditioned on approval of the Share Issuance proposal and on completion of the merger.

Table of Contents


Integrys shareholders are being asked to vote on the following proposals:

1.
to adopt the merger agreement, a copy of which is attached as Annex A to this joint proxy statement/prospectus, which we refer to as the Merger proposal;

2.
to conduct an advisory vote on certain compensation that may be paid or become payable to Integrys' named executive officers that is based on or otherwise relates to the merger, which we refer to as the Merger-Related Compensation proposal; and

3.
to adjourn the Integrys special meeting, if necessary or appropriate, to permit further solicitation of proxies in the event that there are not sufficient votes at the time of the special meeting to approve the Merger proposal, which we refer to as the Integrys Meeting Adjournment proposal.


Approval of the Merger proposal by Integrys shareholders is required for completion of the merger. The approval of the Merger-Related Compensation proposal is not required to complete the merger.


The Share Issuance proposal and the Merger proposal are collectively referred to as the "Merger-Related" proposals.

Q:
Why are Integrys shareholders being asked to approve, on a non-binding advisory basis, the Merger-Related Compensation proposal?

A.
The rules promulgated by the SEC under Section 14A of the Exchange Act require Integrys to seek a non-binding, advisory vote with respect to Merger-Related Compensation. For more information regarding such payments, see "Integrys Proposals—Item 2. The Merger-Related Compensation Proposal" beginning on page 152.

Q:
What will happen if Integrys shareholders do not approve, on a non-binding advisory basis, the Merger-Related Compensation proposal?

A.
The vote on the Merger-Related Compensation proposal is a vote separate and apart from the vote on the Merger proposal. Accordingly, Integrys shareholders may vote in favor of the Merger proposal and not in favor of the Merger-Related Compensation proposal, or vice versa. Approval of the Merger-Related Compensation proposal is not a condition to consummation of the merger, and it is advisory in nature only, meaning it will not be binding on Integrys. Accordingly, because Integrys is contractually obligated to pay such compensation, if the merger is completed, the compensation will be payable, subject only to the conditions applicable to such compensation payments, regardless of the outcome of the advisory vote.

Q:
What vote is required to approve each proposal at the Wisconsin Energy special meeting?

A:
The Share Issuance proposal:    The affirmative vote of a majority of the votes cast by Wisconsin Energy stockholders is required to approve the Share Issuance proposal.


The Name Change proposal:    The affirmative vote of a majority of the shares of Wisconsin Energy common stock outstanding on the record date for the Wisconsin Energy special meeting is required to approve the Name Change proposal.


The Wisconsin Energy Meeting Adjournment proposal:    For the Wisconsin Energy Meeting Adjournment proposal to be approved, the votes cast in favor of the Wisconsin Energy Meeting Adjournment proposal must exceed the votes cast against the proposal.

Table of Contents

Q:
What vote is required to approve each proposal at the Integrys special meeting?

A:
The Merger proposal:    The affirmative vote of a majority of the shares of Integrys common stock outstanding on the record date for the Integrys special meeting is required to approve the Merger proposal.


The Merger-Related Compensation proposal:    The affirmative vote of a majority of the shares of Integrys common stock represented (in person or by proxy) at the Integrys special meeting and entitled to vote on such proposal is required to approve the Merger-Related Compensation proposal. Because the vote on the Merger-Related Compensation proposal is advisory only, it will not be binding on either Integrys or Wisconsin Energy. Accordingly, if the merger agreement is adopted and the merger is completed, the compensation will be payable, subject only to the conditions applicable thereto, regardless of the outcome of the non-binding, advisory vote of Integrys shareholders.


The Integrys Meeting Adjournment proposal:    For the Integrys Meeting Adjournment proposal to be approved, the votes cast in favor of the Integrys Meeting Adjournment proposal must exceed the votes cast against the proposal.

Q:
What constitutes a quorum?

A:
The representation of holders of at least a majority of the total number of shares of common stock outstanding as of the record date at the Wisconsin Energy special meeting or Integrys special meeting, as applicable, whether present in person or represented by proxy, is required in order to conduct business at each special meeting. This requirement is called a quorum. Abstentions, if any, which are described below, will be treated as present for the purposes of determining the presence or absence of a quorum for each special meeting.

Q:
How do the boards of directors of Wisconsin Energy and Integrys recommend that I vote?

A:
The board of directors of Wisconsin Energy, which we refer to as the Wisconsin Energy Board, recommends that holders of Wisconsin Energy common stock vote "FOR" the Share Issuance proposal, "FOR" the Name Change proposal and "FOR" the Wisconsin Energy Meeting Adjournment proposal.


The board of directors of Integrys, which we refer to as the Integrys Board, recommends that Integrys shareholders vote "FOR" the Merger proposal and "FOR" the Integrys Meeting Adjournment proposal. In addition, the Integrys Board recommends that holders of Integrys common stock vote "FOR" the Merger-Related Compensation proposal to approve, on an advisory (non-binding) basis, certain compensation that may be paid or become payable, to Integrys' named executive officers that is based on or otherwise relates to the merger.

Q:
What do I need to do now?

A:
After carefully reading and considering the information contained in, or incorporated by reference into, this joint proxy statement/prospectus, please vote your shares by submitting your proxy as soon as possible so that your shares will be represented at your respective company's special meeting. Please follow the instructions set forth on the proxy card or on the voting instruction form provided by the record holder if your shares are held in the name of your broker, bank or other nominee.

If your shares are held through an employee plan, please see the questions below "What if I participate in Wisconsin Energy's Stock Plus Investment Plan or 401(k) plan?" beginning on page 7 or "What if I participate in Integrys' Employee Stock Ownership Plan, the Peoples Energy Employee Stock Ownership Plan, the Integrys Energy Group 401(k) Plan for Administrative Employees or the Peoples Energy Employee Thrift Plan?" beginning on page 7.

Q:
What does it mean if multiple members of my household are Wisconsin Energy stockholders or Integrys shareholders, as the case may be, but we received only one set of proxy materials for the applicable company?

A:
SEC rules permit public companies, under certain circumstances, to send a single set of proxy materials and annual reports to any household at which two or more stockholders reside if the company believes that they are members of the same family. This procedure, known as householding, reduces the volume of duplicate information you receive and helps to reduce the company's expenses.


In order to take advantage of this opportunity, Wisconsin Energy has delivered one set of proxy materials to Wisconsin Energy stockholders who share an address and Integrys has delivered one set of proxy materials to Integrys shareholders who share an address unless Wisconsin Energy or

Q:
What if I participate in Wisconsin Energy's Stock Plus Investment Plan or 401(k) plan?

A:
If you are a participant in Wisconsin Energy's Stock Plus Investment Plan, which we refer to as Stock Plus, or own shares through investments in the Wisconsin Energy Common Stock ESOP Fund in Wisconsin Energy's 401(k) plan, your proxy will serve as voting instructions for your shares held in those plans. The administrator for Stock Plus and the trustee for the 401(k) plan will vote your shares as you direct. If a proxy is not returned for shares held in Stock Plus, the administrator will not vote those shares. If a proxy is not returned for shares held in the 401(k) plan, the trustee will vote those shares in the same proportion that all shares in the WEC Common Stock ESOP Fund for which voting instructions have been received, are voted.


Stock owned in the 401(k) plan may NOT be voted in person at the Wisconsin Energy special meeting as the plan's trustee votes the plan shares about two days prior to the special meeting, after receiving voting instructions from the plan participants.

Q:
What if I participate in Integrys' Employee Stock Ownership Plan, the Peoples Energy Employee Stock Ownership Plan, the Integrys Energy Group 401(k) Plan for Administrative Employees or the Peoples Energy Employee Thrift Plan?

A:
If you are a participant in Integrys' Employee Stock Ownership Plan, the Peoples Energy Employee Stock Ownership Plan, the Integrys Energy Group 401(k) Plan for Administrative Employees or the Peoples Energy Employee Thrift Plan, which we refer to collectively as the Integrys Share Ownership Plans, your proxy will serve as voting instructions for your shares held in those plans. The trustee of the Integrys Share Ownership Plans will vote the plan shares as instructed by plan participants. If you participate in the Integrys Employee Stock Ownership Plan and you do not provide voting instructions, the trustee will not vote your shares in the plan. If you participate in the Peoples Energy Employee Stock Ownership Plan, the Peoples Energy Employee Thrift Plan or the Integrys Energy Group 401(k) Plan for Administrative Employees and you do not provide voting instructions, the trustee will vote shares allocated to your plan account in the same proportion as those votes cast by other plan participants submitting voting instructions.


Stock owned in these plans may NOT be voted in person at Integrys' special meeting as the plans' trustee votes the plan shares about two days prior to the special meeting, after receiving voting instructions from the plan participants.

Q:
If my shares are held in "street name" by a broker, trustee or other nominee, will my broker, trustee or other nominee vote my shares for me?

A:
If your shares are held in "street name" in a stock brokerage account or by a bank, trustee or other nominee, you must provide the record holder of your shares with instructions on how to vote your shares. Please follow the voting instructions provided by your broker, trustee or other nominee. Please note that you may not vote shares held in street name by returning a proxy card directly to Wisconsin Energy or Integrys or by voting in person at your respective company's special meeting unless you provide a "legal proxy," which you must obtain from your broker, trustee or other

Under the rules of the New York Stock Exchange, which we refer to as the NYSE, brokers who hold shares in street name for a beneficial owner of those shares typically have the authority to vote in their discretion on "routine" proposals when they have not received instructions from beneficial owners. However, brokers are not allowed to exercise their voting discretion with respect to the approval of matters that the NYSE determines to be "non-routine" without specific instructions from the beneficial owner. It is expected that all proposals to be voted on at the Wisconsin Energy special meeting and the Integrys special meeting are such "non-routine" matters. Broker non-votes occur when a broker or nominee is not instructed by the beneficial owner of shares to vote on a particular proposal for which the broker does not have discretionary voting power.


If you are a Wisconsin Energy stockholder and you do not instruct your broker, bank or other nominee on how to vote your shares:

your broker, bank or other nominee may not vote your shares on the Share Issuance proposal, which broker non-votes will have no effect on the vote count for such proposal, except for determining whether a quorum is present;

your broker, bank or other nominee may not vote your shares on the Name Change proposal, which broker non-votes will have the same effect as a vote "AGAINST" such proposal; and

your broker, bank or other nominee may not vote your shares on the Wisconsin Energy Meeting Adjournment proposal, which broker non-votes will have no effect on the vote count for this proposal.


If you are an Integrys shareholder and you do not instruct your broker, bank or other nominee on how to vote your shares:

your broker, bank or other nominee may not vote your shares on the Merger proposal, which broker non-votes will have the same effect as a vote "AGAINST" this proposal;

your broker, bank or other nominee may not vote your shares on the Merger-Related Compensation proposal, which broker non-votes will have no effect on the vote count for this proposal; and

your broker, bank or other nominee may not vote your shares on the Integrys Meeting Adjournment proposal, which broker non-votes will have no effect on the vote count for this proposal.

Q:
What if I fail to vote or abstain?

A:
For purposes of each of the Wisconsin Energy special meeting and the Integrys special meeting, an abstention occurs when a stockholder attends the applicable special meeting in person and does not vote or returns a proxy with an "abstain" vote.

Share Issuance proposal:    An abstention will have the same effect as a vote cast "AGAINST" the Share Issuance proposal. If a Wisconsin Energy stockholder is not present in person at the Wisconsin Energy special meeting and does not respond by proxy, it will have no effect on the vote count for the Share Issuance proposal.


Name Change proposal:    An abstention or failure to vote will have the same effect as a vote cast "AGAINST" the Name Change proposal.

Table of Contents


Wisconsin Energy Meeting Adjournment proposal:    An abstention will have no effect on the vote count for the Wisconsin Energy Meeting Adjournment proposal.

Merger proposal:    An abstention or failure to vote will have the same effect as a vote cast "AGAINST" the Merger proposal.


Merger-Related Compensation proposal:    An abstention will have the same effect as a vote cast "AGAINST" the Merger-Related Compensation proposal. If an Integrys shareholder is not present in person at the Integrys special meeting and does not respond by proxy, it will have no effect on the vote count for the Merger-Related Compensation proposal (assuming a quorum is present).


Integrys Meeting Adjournment proposal:    An abstention will have no effect on the vote count for the Integrys Meeting Adjournment proposal.

Q:
What will happen if I return my proxy or voting instruction card without indicating how to vote?

A:
If you properly sign and return your proxy or voting instruction card without indicating how to vote on any particular proposal, the Wisconsin Energy common stock represented by your proxy will be voted as recommended by the Wisconsin Energy Board with respect to that proposal and/or the Integrys common stock represented by your proxy will be voted as recommended by the Integrys Board with respect to that proposal. The proxyholders may use their discretion to vote on other matters that are properly brought before the Wisconsin Energy special meeting or the Integrys special meeting, as applicable.

Q:
What if I hold shares of both Wisconsin Energy common stock and Integrys common stock?

A:
If you are a stockholder of Wisconsin Energy and also a shareholder of Integrys, you will receive two separate packages of proxy materials. A vote as an Integrys shareholder will not constitute a vote as a Wisconsin Energy stockholder and vice versa. Therefore, please sign, date and return all proxy cards that you receive, whether from Wisconsin Energy or Integrys, or vote as both a Wisconsin Energy stockholder and as an Integrys shareholder by Internet or telephone.

Q:
May I change my vote after I have delivered my proxy or voting instruction card?

A:
Yes. If you are a record holder, you may change your vote at any time before your proxy is voted at the Wisconsin Energy special meeting or the Integrys special meeting, as applicable. You may do this in one of four ways:

by sending a notice of revocation to the corporate secretary of Wisconsin Energy or Integrys Investor Relations, as applicable;

by logging onto the Internet website specified on your proxy card in the same manner you would to submit your proxy electronically or by calling the telephone number specified on your proxy card, in each case if you are eligible to do so;

by sending a completed proxy card bearing a later date than your original proxy card; or

by attending the Wisconsin Energy special meeting or the Integrys special meeting, as applicable, and voting in person.


The Internet and telephone voting facilities for the Wisconsin Energy special meeting will close at 10:59 p.m., Central time, on November 20, 2014. The Internet and telephone voting facilities for the Integrys special meeting will close at 10:59 p.m., Central time, on November 20, 2014; provided, however, that votes representing shares held in the Integrys Share Ownership Plans must be received

Q:
What are the U.S. federal income tax consequences of the merger?

A:
It is a condition to the obligation of Integrys to complete the merger that Integrys receive a written opinion from Cravath, Swaine & Moore LLP, counsel to Integrys, which we refer to as Cravath, dated as of the completion of the merger, to the effect that for U.S. federal income tax purposes the initial merger and the subsequent merger, taken together as a single integrated transaction, qualify as a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, which we refer to as the Code.


It is a condition to the obligation of Wisconsin Energy to complete the merger that Wisconsin Energy receive a written opinion from Skadden, Arps, Slate, Meagher & Flom LLP, counsel to Wisconsin Energy, which we refer to as Skadden, dated as of the completion of the merger, to the effect that for U.S. federal income tax purposes the initial merger and the subsequent merger, taken together as a single integrated transaction, qualify as a "reorganization" within the meaning of Section 368(a) of the Code.


An Integrys shareholder who, consistent with such opinions, receives cash (other than cash in lieu of a fractional share of Wisconsin Energy common stock) and shares of Wisconsin Energy common stock pursuant to a transaction constituting a reorganization within the meaning of Section 368(a) of the Code will recognize gain (but will not recognize any loss), and the gain recognized will be equal to the lesser of (i) any cash received (other than cash received in lieu of a fractional share of Wisconsin Energy common stock) and (ii) the excess, if any, of (x) the sum of the cash received (including cash received in lieu of a fractional share of Wisconsin Energy common stock) and the fair market value (determined at the effective time of the merger) of the Wisconsin Energy common stock received over (y) such Integrys shareholder's tax basis in the shares of Integrys common stock exchanged therefor. In addition, such Integrys shareholder will recognize gain or loss attributable to cash received in lieu of a fractional share of Wisconsin Energy common stock. Integrys shareholders should consult their tax advisors for a full understanding of all of the tax consequences of the offer and the merger to them.

Q:
Do I have dissenter's rights in connection with the merger?

A:
No. Under Wisconsin law, neither Integrys shareholders nor Wisconsin Energy stockholders will be entitled to exercise any dissenters' rights in connection with the merger or the other transactions contemplated by the merger agreement.

Q:
What if I hold Integrys stock options or restricted stock units?

A:
In connection with the merger:

Each Integrys stock option that is outstanding immediately prior to the completion of the merger, whether vested or unvested, will be cancelled in exchange for the right to receive a cash payment equal to the number of shares of Integrys common stock subject to the Integrys stock option multiplied by the excess of (i) the sum of (x) the cash consideration and (y) 1.128 multiplied by the average of the volume weighted average price per share of Wisconsin Energy common stock

The Parties (Page 139)

        Wisconsin Energy was incorporated in the state of Wisconsin in 1981 and became a diversified energy holding company in 1986. Wisconsin Energy maintains its principal executive offices in Milwaukee, Wisconsin.

        Wisconsin Energy conducts its operations primarily in two reportable segments: a utility energy segment and a non-utility energy segment. Wisconsin Energy's primary subsidiaries are Wisconsin Electric Power Company, which we refer to as Wisconsin Electric, Wisconsin Gas LLC, which we refer to as Wisconsin Gas, and W.E. Power, LLC, which we refer to as We Power. In addition, Wisconsin Energy has a 26.24 percent equity interest in American Transmission Company LLC (an electric transmission company operating in Illinois, Michigan, Minnesota and Wisconsin, and which we refer to as ATC).

        For the year ended December 31, 2013, Wisconsin Energy had total operating revenues of approximately $4.5 billion and total net income from continuing operations of approximately $577.4 million. For the six months ended June 30, 2014, Wisconsin Energy had total operating revenues of approximately $2.7 billion and total net income from continuing operations of approximately $340.6 million.

        Integrys is a diversified energy holding company headquartered in Chicago, Illinois. Integrys was incorporated in Wisconsin in 1993. Its wholly owned subsidiaries provide products and services in both the regulated and nonregulated energy markets. In addition, Integrys has a 34.07 percent equity interest in ATC. Integrys has five reportable segments: regulated natural gas utility operations, regulated electric utility operations, Integrys energy services, electric transmission investment and holding company and other. On July 30, 2014, Integrys announced that it has agreed to sell its competitive retail electric and natural gas businesses through a sale of all of the issued and outstanding shares of capital stock of its wholly-owned subsidiary, Integrys Energy Services, Inc., to Exelon Generation Company, LLC, which we refer to as the IES Sale. The IES Sale will not include the Integrys' generation and solar asset businesses which will be moved from Integrys Energy Services, Inc. to Integrys or one of its affiliates. The IES Sale is expected to close the fourth quarter of 2014 or the first quarter of 2015.

        For the year ended December 31, 2013, Integrys had total revenues of approximately $5.6 billion and total net income attributed to common shareholders of approximately $351.8 million. For the six months ended June 30, 2014, Integrys had total revenues of approximately $4.4 billion and total net income attributed to common shareholders of approximately $159.6 million.

Table of Contents

        WEC Acquisition Corp., which we refer to as merger sub, and GET Acquisition Corp., which we refer to as subsequent merger sub, are Wisconsin corporations formed on July 10, 2014 for the purpose of completing the merger. Each of merger sub and subsequent merger sub is a direct, wholly owned subsidiary of Wisconsin Energy and became party to the merger agreement through execution of a joinder agreement.


The Merger (Page 114)

        Pursuant to and in accordance with the merger agreement, in the initial merger, merger sub will merge with and into Integrys, with Integrys continuing as the surviving corporation and a wholly owned subsidiary of Wisconsin Energy. Immediately thereafter, Integrys will merge with and into subsequent merger sub, with subsequent merger sub continuing as the surviving corporation and a wholly owned subsidiary of Wisconsin Energy.

        The initial merger and the subsequent merger are referred to collectively in this joint proxy statement/prospectus as the merger.

        The merger will be completed only after the satisfaction or waiver of the conditions to the completion of the merger discussed below.

        The merger agreement is attached as Annex A to this joint proxy statement/prospectus. Wisconsin Energy and Integrys encourage you to read the merger agreement carefully and fully, as it is the legal document that governs the merger.


Consideration to be Received in the Merger by Integrys Shareholders (Page 114)

        In the merger, each share of Integrys common stock that is issued and outstanding immediately prior to the effective time of the initial merger (other than any shares of Integrys common stock owned or held directly or indirectly by Integrys, Wisconsin Energy, Merger Sub or Subsequent Merger Sub, which will be cancelled upon completion of the merger) will be converted into the right to receive 1.128 shares of Wisconsin Energy common stock, which we refer to as the stock consideration, and $18.58 in cash, which we refer to as the cash consideration. The stock consideration and cash consideration are collectively referred to as the merger consideration. Based on the closing price of Wisconsin Energy common stock on June 20, 2014, the last trading day before the public announcement of the merger, the aggregate value of the merger consideration was approximately $5.8 billion. Shares of Integrys common stock held by grantor trusts of Integrys will not be cancelled but will instead be converted into the right to receive the merger consideration. The merger consideration will be adjusted appropriately to fully reflect the effect of any stock dividend, subdivision, reclassification, recapitalization, split, combination, consolidation or exchange of shares, or any similar event. No fractional shares of Wisconsin Energy common stock will be issued in connection with the merger, and holders of fractional shares of Integrys common stock will be entitled to receive cash in lieu thereof.


Treatment of Equity-Based Awards (Page 116)

        Upon completion of the merger, outstanding Integrys equity awards, including options, time-based restricted stock units, performance-based restricted stock units and deferred stock units, in each case, whether vested or unvested, will be cancelled. In connection with the merger:

        The merger will not affect Wisconsin Energy's stock options, restricted stock or other equity awards. All such awards will remain outstanding subject to the same terms and conditions that are applicable prior to the merger.

Name Change; Headquarters; Community Involvement (Page 89)

        In connection with the merger, if the Name Change proposal is approved, Wisconsin Energy will amend its charter to change its name from "Wisconsin Energy Corporation" to "WEC Energy Group, Inc." effective upon completion of the merger.

        Upon completion of the merger, Wisconsin Energy has agreed to take all necessary action to cause (i) its corporate headquarters and principal executive offices to be located in metropolitan Milwaukee, Wisconsin, and (ii) its operational headquarters to be located in Milwaukee, Wisconsin, Chicago, Illinois, and Green Bay, Wisconsin.

        Upon completion of the merger, Wisconsin Energy has agreed to maintain historic levels of community involvement and charitable contributions in Integrys' and its subsidiaries' existing service territories following the merger.


Recommendations of the Wisconsin Energy Board of Directors (Page 52)

        After careful consideration, the Wisconsin Energy Board recommends that holders of Wisconsin Energy common stock vote "FOR" the Share Issuance proposal, the Name Change proposal and the Wisconsin Energy Meeting Adjournment proposal.

Opinions of Financial Advisors (Page 64)

        In connection with the merger, on June 22, 2014, Barclays Capital Inc., which we refer to as Barclays, rendered its oral opinion (which was subsequently confirmed in writing on the same date) to the Wisconsin Energy Board that, as of such date and based upon and subject to the qualifications, limitations and assumptions stated in its opinion, the merger consideration to be paid by Wisconsin Energy in the merger is fair, from a financial point of view, to Wisconsin Energy.

        The full text of Barclays' written opinion, dated June 22, 2014, which sets forth, among other things, the assumptions made, procedures followed, factors considered and limitations upon the review undertaken by Barclays in rendering its opinion, is attached as Annex B to this joint proxy statement/prospectus and is incorporated by reference herein in its entirety.

        Barclays' opinion, the issuance of which was approved by Barclays' Valuation and Fairness Opinion Committee, is addressed to the Wisconsin Energy Board, addresses only the fairness, from a financial point of view, to Wisconsin Energy of the merger consideration to be paid by Wisconsin Energy and does not constitute a recommendation to any stockholder of Wisconsin Energy as to how such stockholder should vote with respect to the proposed transaction or any other matter. Barclays was not requested to address, and its opinion does not in any manner address, Wisconsin Energy's underlying business decision to proceed with or effect the proposed transaction. In addition, Barclays expressed no opinion on, and its opinion does not in any manner address, the fairness of the amount or the nature of any compensation to any officers, directors or employees of any parties to the proposed transaction, or any class of such persons, relative to the consideration paid in the proposed transaction or otherwise. Under the terms of Barclays' engagement, Wisconsin Energy has agreed to pay Barclays a fee for its financial advisory services in connection with the merger, a significant portion of which is contingent upon completion of the merger.

        See "The Merger—Opinions of Financial Advisors—Opinion of Wisconsin Energy's Financial Advisor" beginning on page 64.

        On June 21, 2014, Integrys' financial advisor, Lazard Frères & Co. LLC, which we refer to as Lazard, rendered its written opinion, consistent with its oral opinion rendered on the same date, to the Integrys Board that, as of such date, and based upon and subject to the assumptions, procedures, factors, qualifications and limitations set forth therein, the merger consideration of (x) 1.128 shares of the common stock, par value $0.01 per share, of Wisconsin Energy and (y) $18.58 in cash per share of Integrys common stock to be paid to the holders of Integrys' common stock (other than to (i) Integrys (as the holder of treasury shares but not in respect of the shares held by Integrys' rabbi trusts) and (ii) Wisconsin Energy or the merger subs, which are collectively referred to as excluded holders) in the merger was fair, from a financial point of view, to such holders.

        The full text of Lazard's written opinion, dated June 21, 2014, which sets forth the assumptions made, procedures followed, factors considered and qualifications and limitations on the review undertaken by Lazard in connection with its opinion, is attached to this registration statement as

Annex C and is incorporated by reference herein in its entirety. The foregoing summary of Lazard's opinion is qualified in its entirety by reference to the full text of the opinion. You are encouraged to read Lazard's opinion, this section and the further discussion of Lazard's opinion included elsewhere in this prospectus carefully and in their entirety. Lazard's engagement and its opinion were for the benefit of the Integrys Board (in its capacity as such), and Lazard's opinion was rendered to the Integrys Board in connection with its evaluation of the merger and addressed only the fairness as of the date of the opinion, from a financial point of view, to holders of Integrys common stock (other than the "excluded holders") of the merger consideration to be paid to such holders in the merger. Lazard's opinion was not intended to, and does not, constitute a recommendation to any shareholder as to how such shareholder should vote or act with respect to the merger or any matter relating thereto. In addition, Lazard expressed no opinion on, and its opinion does not in any manner address, the fairness of the amount or the nature of any compensation to any officers, directors or employees of any parties to the proposed transaction, or any class of such persons, relative to the consideration paid in the proposed transaction or otherwise. Under the terms of Lazard's engagement, Integrys has agreed to pay Lazard a fee for its financial advisory services in connection with the merger, a significant portion of which is contingent upon completion of the merger.

These interests include (i) the acceleration and "cash-out" of Integrys stock options, Time-Based RSUs, Performance-Based RSUs and Deferred Stock Units; (ii) certain severance benefits that may be payable upon termination following the consummation of the merger; (iii) accelerated vesting of certain pension or retirement benefits, and (iv) entitlement to continued indemnification and insurance coverage under the merger agreement. In addition, three members from the Integrys Board, who are to be selected by Integrys in consultation with Wisconsin Energy and subject to certain qualifications, will serve on the board of directors of the combined company.


U.S. Federal Income Tax Consequences of the Merger (Page 108)

        It is a condition to the obligation of Integrys to complete the merger that Integrys receive a written opinion from Cravath, counsel to Integrys, dated as of the completion of the merger, to the effect that for U.S. federal income tax purposes the initial merger and the subsequent merger, taken together as a single integrated transaction, qualify as a "reorganization" within the meaning of Section 368(a) of the Code. It is a condition to the obligation of Wisconsin Energy to complete the merger that Wisconsin Energy receive a written opinion from Skadden, counsel to Wisconsin Energy, dated as of the completion of the merger, to the effect that for U.S. federal income tax purposes the initial merger and the subsequent merger, taken together as a single integrated transaction, qualify as a "reorganization" within the meaning of Section 368(a) of the Code. An Integrys shareholder who, consistent with such opinions, receives cash (other than cash in lieu of a fractional share of Wisconsin Energy common stock) and shares of Wisconsin Energy common stock pursuant to a transaction constituting a reorganization within the meaning of Section 368(a) of the Code will recognize gain (but will not recognize any loss), and the gain recognized will be equal to the lesser of (i) any cash received (other than cash received in lieu of a fractional share of Wisconsin Energy common stock) and (ii) the excess, if any, of (x) the sum of the cash received (including cash received in lieu of a fractional share of Wisconsin Energy common stock) and the fair market value (determined at the effective time of the merger) of the Wisconsin Energy common stock received over (y) such Integrys shareholder's tax basis in the shares of Integrys common stock exchanged therefor. In addition, such Integrys shareholder will recognize gain or loss attributable to cash received in lieu of a fractional share of Wisconsin Energy common stock. Integrys shareholders should consult their tax advisors for a full understanding of all of the tax consequences of the offer and the merger to them.

        The discussion of the U.S. federal income tax consequences of the merger contained in this joint proxy statement/prospectus is intended to provide only a general summary and is not a complete analysis or description of all potential U.S. federal income tax consequences of the merger. The discussion does not address tax consequences that may vary with, or are contingent on, individual circumstances. In addition, it does not address the effects of any foreign, state or local tax laws.

        Integrys shareholders are strongly urged to consult with their tax advisors regarding the tax consequences of the merger to them, including the effects of U.S. federal, state, local, foreign and other tax laws.


Accounting Treatment of the Merger
(Page 101)

        Wisconsin Energy prepares its financial statements in accordance with accounting principles generally accepted in the United States. The merger will be accounted for by applying the acquisition method with Wisconsin Energy treated as the acquiror.


Dissenters' Rights (Page 108)

Regulatory Matters (Page 101)

        To complete the merger, Wisconsin Energy and Integrys must obtain certain authorizations, approvals or consents from a number of federal and state public utility, antitrust, and other regulatory authorities. There are certain filings, notices and waiting periods required in order for Wisconsin Energy and Integrys to obtain these required authorizations, approvals or consents. These include notifications to and authorizations, approvals or consents from the Federal Energy Regulatory Commission, which we refer to as the FERC, Federal Communications Commission, which we refer to as the FCC, Public Service Commission of Wisconsin, which we refer to as the PSCW, the Illinois Commerce Commission, which we refer to as the ICC, the Michigan Public Service Commission, which we refer to as the MPSC, and the Minnesota Public Utilities Commission, which we refer to as the MPUC. The transaction is also subject to the notification, clearance and reporting requirements under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, which we refer to as the HSR Act. We are not currently aware of any other material governmental filings, authorizations, approvals or consents that are required prior to the completion of the merger.


NYSE Listing of Wisconsin Energy Common Stock; Delisting and Deregistration of Integrys Common Stock (Page 108)

        Prior to the completion of the merger, Wisconsin Energy has agreed to use its commercially reasonable efforts to cause the shares of Wisconsin Energy to be issued in the merger to be approved for listing on the NYSE. If the merger is completed, Integrys common stock will cease to be listed on the NYSE and Integrys common stock will be deregistered under the Securities Exchange Act of 1934, as amended, which we refer to as the Exchange Act.


Continued NYSE Listing of Wisconsin Energy Common Stock (Page 108)

        Shares of Wisconsin Energy common stock are expected to continue trading on the NYSE under the symbol "WEC" whether or not the merger is completed.


Litigation Related to the Merger (Page 112)

        In connection with the merger, purported shareholders of Integrys have filed putative class action lawsuits against Integrys, members of the Integrys Board and Wisconsin Energy, among others. The lawsuits generally allege, among other things, that the directors of Integrys breached their fiduciary duties to Integrys shareholders in connection with the merger. The lawsuits further allege that Integrys and Wisconsin Energy, among others, aided and abetted the Integrys directors in the breach of fiduciary duties. The lawsuits seek injunctive relief enjoining the merger, damages and costs, among other remedies.

        These lawsuits are in a preliminary stage. Integrys and Wisconsin Energy believe that the lawsuits are without merit and intend to defend these lawsuits vigorously.


Conditions to Completion of the Merger (Page 117)

        The obligations of each of Wisconsin Energy and Integrys to complete the merger are subject to the satisfaction of the following conditions:

Table of Contents

        In addition, the obligation of Wisconsin Energy to complete the initial merger is subject to the satisfaction of the condition that no legal restraint is in effect, and no proceeding is pending before any governmental entity seeking to impose any condition that, individually or in the aggregate, has resulted in or would reasonably be expected to result in a "parent regulatory material adverse effect." A

Table of Contents

"parent regulatory material adverse effect" is defined to mean any material adverse effect on the business, properties, financial condition or results of operations of Wisconsin Energy and its subsidiaries or of Integrys and its subsidiaries, in each case, taken as whole, except that, for purposes of determining whether an effect would constitute a parent regulatory material adverse effect, Wisconsin Energy and its subsidiaries, taken as a whole, will be deemed to be a consolidated group of entities the size and scale of Integrys and its subsidiaries, taken as whole.


Treatment of Integrys' Existing Debt; Financing (Page 106)

        There are no financing conditions to the merger and the merger is not conditioned upon the completion of the change of control refinancing, as described herein, or obtaining the financing to fund the cash consideration payable in the merger or otherwise consummate the transactions contemplated by the merger agreement.

        In connection with the merger agreement, if Wisconsin Energy submits a written request, Integrys will commence a tender offer to purchase Integrys' 8.00% senior notes, due June 1, 2016. To the extent that any of the notes are not validly tendered pursuant to that tender offer, or are tendered but then withdrawn, Integrys will make arrangements with the note holders' trustee to deliver a notice of optional prepayment for the notes, and will deposit funds with the trustee sufficient to prepay the untendered notes, in accordance with the terms of the indenture documents. This tender offer and notice of prepayment we refer to as the change of control refinancing.

        The change of control refinancing will be conditioned on completion of the merger. The merger is not conditioned on the change of control refinancing, and there are no other financing conditions to the merger.

        Under the merger agreement, Wisconsin Energy represents that it will have sufficient funds to consummate the merger and the other transactions contemplated by the merger agreement. Wisconsin Energy did not provide any commitment letters from lenders when the merger agreement was signed, but has agreed to use its reasonable best efforts to: (i) obtain the necessary funds from lenders to consummate the merger and the other transactions contemplated by the merger agreement; (ii) repay or refinance any outstanding indebtedness that becomes due and payable as a result of the merger; (iii) pay any fees and expenses required to be paid by Wisconsin Energy, merger sub and subsequent merger sub in connection with the merger and the financing; and (iv) satisfy any other payment obligations of Wisconsin Energy, merger sub or subsequent merger sub contemplated by the merger agreement.

        Integrys has agreed to cooperate with Wisconsin Energy in connection with obtaining the financing, within limits specified in the merger agreement.

        Barclays has delivered to Wisconsin Energy a "highly confident" letter with respect to securing financing for the cash consideration of the merger.


Timing of the Merger

        The merger is expected to be completed in the second half of 2015.

        The merger agreement does not, however, prohibit either party from considering an unsolicited acquisition proposal from a third party if certain specified conditions are met.


Termination of the Merger Agreement; Termination Fees (Page 136)

        Generally, the merger agreement may be terminated and the merger may be abandoned at any time prior to completion of the merger, as specified below:

        As of the Wisconsin Energy record date, directors and executive officers of Wisconsin Energy and their affiliates owned and were entitled to vote 2,628,197 shares of Wisconsin Energy common stock, representing approximately 1.17 percent of the total voting power of the shares of Wisconsin Energy common stock outstanding on that date.

Dividends Policy

        Under the merger agreement, Wisconsin Energy and Integrys have agreed to coordinate with each other regarding the declaration and payment of dividends in respect of their common stock and the record dates and payment dates relating thereto, so to as ensure proper payment to stockholders of quarterly dividends with respect to their respective shares of Wisconsin Energy common stock and Integrys common stock.

        Further, under the merger agreement, the Wisconsin Energy board agreed to adopt and approve a new dividend policy to take effect upon completion of the merger relating to the payment of dividends on the outstanding Wisconsin Energy common stock after completion of the merger. The dividend policy will provide for a quarterly dividend per share of Wisconsin Energy common stock in an amount equal to the quarterly dividend amount paid per share by Integrys on the outstanding Integrys common stock on Integrys' most recent dividend payment date before completion of the merger divided by a dividend exchange ratio. As defined in the merger agreement, the dividend exchange ratio will be calculated by dividing the value of the merger consideration by the average of the volume weighted average price per share of Wisconsin Energy common stock on the NYSE on each of the 10 consecutive trading days ending with the second complete trading day prior to the completion of the merger.

        For further details regarding dividends, see "The Merger Agreement—Dividends" on page 135.


Merger and Market Share Price

        Shares of Wisconsin Energy common stock are listed and trade on the NYSE under the symbol "WEC". Shares of Integrys common stock are listed and trade on the NYSE under the symbol "TEG".

        The following table presents the closing sales prices of shares of Wisconsin Energy common stock and Integrys common stock, each as reported by the NYSE, on (i) June 20, 2014, the last trading day before various news outlets began reporting on a possible transaction involving Wisconsin Energy and Integrys and (ii) October 13, 2014, the last practicable trading day prior to the date of this joint proxy statement/prospectus. The table also presents the equivalent market value per share of Integrys common stock as of each such date, determined as described in the footnote accompanying the table.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

        This joint proxy statement/prospectus contains certain forward-looking statements with respect to the financial condition, results of operations and business of Wisconsin Energy and Integrys and the combined businesses of Integrys and Wisconsin Energy and certain plans and objectives of Wisconsin Energy and Integrys with respect thereto, including the expected benefits of the merger. These forward-looking statements can be identified by the fact that they do not relate only to historical or current facts. Forward-looking statements often use words such as "anticipate", "target", "expect", "estimate", "intend", "plan", "goal", "believe", "hope", "aim", "continue", "will", "may", "would", "could" or "should" or other words of similar meaning or the negative thereof. There are several factors which could cause actual plans and results to differ materially from those expressed or implied in forward-looking statements.

        Such factors include, but are not limited to, those set forth under "Risk Factors" beginning on page 31 as well as, among others, the following:

        These forward-looking statements are based on numerous assumptions and assessments made by Wisconsin Energy and/or Integrys in light of their experience and perception of historical trends, current conditions, business strategies, operating environment, future developments and other factors that each party believes appropriate. By their nature, forward-looking statements involve known and unknown risks and uncertainties because they relate to events and depend on circumstances that will occur in the future. The factors described in the context of such forward-looking statements in this joint proxy statement/prospectus could cause actual results, performance or achievements, industry results and developments to differ materially from those expressed in or implied by such forward-looking statements. Although it is believed that the expectations reflected in such forward-looking statements are reasonable, no assurance can be given that such expectations will prove to have been correct and persons reading this joint proxy statement/prospectus are therefore cautioned not to place undue reliance on these forward-looking statements which speak only as of the date of this joint proxy statement/prospectus. Neither Wisconsin Energy nor Integrys assumes any obligation to update the information contained in this joint proxy statement/prospectus (whether as a result of new information, future events or otherwise), except as required by applicable law.

        A further list and description of risks and uncertainties at Wisconsin Energy can be found in Wisconsin Energy's Annual Report on Form 10-K for the fiscal year ended December 31, 2013 and in its reports filed on Form 10-Q and Form 8-K. A further list and description of risks and uncertainties at Integrys can be found in Integrys' Annual Report on Form 10-K for the fiscal year ended December 31, 2013 and in its reports filed on Form 10-Q and Form 8-K. See "Where You Can Find More Information" beginning on page 174 for a list of the SEC documents incorporated by reference herein.

RISK FACTORS

        In addition to the other information included or incorporated by reference into this joint proxy statement/prospectus, including the matters addressed in "Cautionary Note Regarding Forward-Looking Statements" on page 31, you should carefully consider the following risks before deciding how to vote.


Risks Related to the Merger

Because the merger consideration is fixed and the market price of shares of Wisconsin Energy common stock will fluctuate, Integrys shareholders cannot be sure of the value of the merger consideration they will receive.

        Upon completion of the merger, each outstanding share of Integrys common stock will be converted into the right to receive 1.128 shares of Wisconsin Energy common stock and $18.58 in cash. Based on the closing price of Wisconsin Energy common stock on June 20, 2014, the last trading day before the public announcement of the merger, the aggregate value of the merger consideration was approximately $5.8 billion. The number of shares of Wisconsin Energy common stock to be issued pursuant to the merger agreement for each share of Integrys common stock is fixed and will not change to reflect changes in the market price of Wisconsin Energy or Integrys common stock. Because the exchange ratio will not be adjusted to reflect any changes in the market value of Wisconsin Energy common stock or Integrys common stock, the market value of the Wisconsin Energy common stock issued in connection with the merger and the Integrys common stock surrendered in connection with the merger may be higher or lower than the values of those shares on earlier dates. Stock price changes may result from, among other things, changes in the business, operations or prospects of Wisconsin Energy or Integrys prior to or following the merger, litigation or regulatory considerations, general business, market, industry or economic conditions and other factors both within and beyond the control of Wisconsin Energy and Integrys. The market price of Wisconsin Energy common stock at the time of completion of the merger may vary significantly from the market prices of Wisconsin Energy common stock on the date the merger agreement was executed, the date of this joint proxy statement/prospectus and the date of the respective special meetings. Accordingly, at the time of the Integrys special meeting, you will not know or be able to calculate the market value of the merger consideration you will receive upon completion of the merger. Neither Wisconsin Energy nor Integrys is permitted to terminate the merger agreement solely because of changes in the market price of either company's common stock.

Current Wisconsin Energy stockholders and Integrys shareholders will have a reduced ownership and voting interest after the merger.

        As a result of the issuance of Wisconsin Energy common stock to Integrys shareholders in the merger, current Wisconsin Energy stockholders and Integrys shareholders are expected to hold approximately 72 percent and 28 percent, respectively, of the combined company's outstanding common stock immediately following completion of the merger.

        Wisconsin Energy stockholders and Integrys shareholders currently have the right to vote for their respective directors and on other matters affecting the applicable company. When the merger occurs, each Integrys shareholder that receives shares of Wisconsin Energy common stock will become a stockholder of Wisconsin Energy with a percentage ownership of the combined company that will be smaller than the shareholder's percentage ownership of Integrys. Correspondingly, each Wisconsin Energy stockholder will remain a stockholder of Wisconsin Energy with a percentage ownership of the combined company that will be smaller than the stockholder's percentage of Wisconsin Energy prior to the merger. As a result of these reduced ownership percentages, Wisconsin Energy stockholders will have less voting power in the combined company than they now have with respect to Wisconsin Energy, and former Integrys shareholders will have less voting power in the combined company than they now have with respect to Integrys.

Table of Contents

The merger agreement limits each of Wisconsin Energy's and Integrys' ability to pursue alternatives to the merger, which could discourage a potential acquirer of either Integrys or Wisconsin Energy from making an alternative transaction proposal and, in certain circumstances, could require Wisconsin Energy or Integrys to pay to the other a significant termination fee.

        Under the merger agreement, Wisconsin Energy and Integrys are restricted, subject to limited exceptions, from pursuing or entering into alternative transactions in lieu of the merger. In general, unless and until the merger agreement is terminated, both Wisconsin Energy and Integrys are restricted from, among other things, soliciting, initiating, knowingly encouraging, inducing or knowingly facilitating a competing acquisition proposal from any person. Each of the Wisconsin Energy Board and the Integrys Board is limited in its ability to change its recommendation with respect to the merger-related proposals. Wisconsin Energy or Integrys may terminate the merger agreement and enter into an agreement with respect to a superior offer only if specified conditions have been satisfied, including compliance with the non-solicitation provisions of the merger agreement, the expiration of certain waiting periods during which the other party may propose changes to the merger agreement so the superior offer is no longer a superior offer and the payment of the required termination fee. These provisions could discourage a third party that may have an interest in acquiring all or a significant part of Wisconsin Energy or Integrys from considering or proposing such an acquisition, even if such third party were prepared to pay consideration with a higher per share cash or market value than the consideration proposed to be received or realized in the merger, or might result in a potential acquirer proposing to pay a lower price than it would otherwise have proposed to pay because of the added expense of the termination fee that may become payable. As a result of these restrictions, neither Wisconsin Energy nor Integrys may be able to enter into an agreement with respect to a more favorable alternative transaction without incurring potentially significant liability to the other. See "The Merger Agreement—No Solicitation" beginning on page 125 and "The Merger Agreement—Board Recommendation, Termination for Superior Proposal and Adverse Recommendation Changes" beginning on page 127.

Wisconsin Energy and Integrys will be subject to various uncertainties and contractual restrictions while the merger is pending that could adversely affect their financial results.

        Uncertainty about the effect of the merger on employees, suppliers and customers may have an adverse effect on Wisconsin Energy and/or Integrys. These uncertainties may impair Wisconsin Energy's and/or Integrys' ability to attract, retain and motivate key personnel until the merger is completed and for a period of time thereafter, and could cause customers, suppliers and others who deal with Wisconsin Energy or Integrys to seek to change existing business relationships with Wisconsin Energy or Integrys. Employee retention and recruitment may be particularly challenging prior to completion of the merger, as employees and prospective employees may experience uncertainty about their future roles with the combined company.

        The pursuit of the merger and the preparation for the integration of the two companies may place a significant burden on management and internal resources. Any significant diversion of management attention away from ongoing business and any difficulties encountered in the transition and integration process could affect the financial results of Wisconsin Energy, Integrys and/or the combined company.

        In addition, the merger agreement restricts each of Wisconsin Energy and Integrys, without the other's consent, from making certain acquisitions and dispositions and taking other specified actions while the merger is pending. These restrictions may prevent Wisconsin Energy and/or Integrys from pursuing attractive business opportunities and making other changes to their respective businesses prior to completion of the merger or termination of the merger agreement. See "The Merger Agreement—Conduct of Business Prior to Closing" beginning on page 121.

Table of Contents

If completed, the merger may not achieve its intended results, and Wisconsin Energy and Integrys may be unable to successfully integrate their operations.

        Wisconsin Energy and Integrys entered into the merger agreement with the expectation that the merger will result in various benefits, including, among other things, accretion to the combined company's earnings per share in the first full calendar year following completion of the merger. Achieving the anticipated benefits of the merger is subject to a number of uncertainties, including whether the businesses of Wisconsin Energy and Integrys can be integrated in an efficient and effective manner, whether U.S. federal and state public utility, antitrust and other regulatory authorities whose approval is required to complete the merger impose conditions on the completion of the merger, which may have an adverse effect on the combined company, including its ability to achieve the anticipated benefits of the merger, general market and economic conditions, general competitive factors in the marketplace and higher than expected costs required to achieve the anticipated benefits of the merger.

        It is possible that the integration process could take longer than anticipated and could result in the loss of valuable employees, the disruption of each company's ongoing businesses, processes and systems or inconsistencies in standards, controls, procedures, practices, policies and compensation arrangements, any of which could adversely affect the combined company's ability to achieve the anticipated benefits of the merger. The combined company's results of operations could also be adversely affected by any issues attributable to either company's operations that arise or are based on events or actions that occur prior to the closing of the merger. The companies may have difficulty addressing possible differences in corporate cultures and management philosophies. The integration process is subject to a number of uncertainties, and no assurance can be given that the anticipated benefits will be realized or, if realized, the timing of their realization. Failure to achieve these anticipated benefits could result in increased costs or decreases in the amount of expected revenues and could adversely affect the combined company's future business, financial condition, operating results and prospects.

Pending litigation against Wisconsin Energy and Integrys could result in an injunction preventing completion of the merger, the payment of damages in the event the merger is completed and/or may adversely affect the combined company's business, financial condition or results of operations following the merger.

        In connection with the merger, purported shareholders of Integrys have filed putative stockholder class action lawsuits against Integrys and its directors and Wisconsin Energy. Among other remedies, the plaintiffs seek to enjoin the merger. See "The Merger—Litigation Related to the Merger" on page 112. In addition, one of the conditions to the closing of the merger is that no law or judgment issued by any court of competent jurisdiction shall be in effect that, and no suit, action or other proceeding shall be pending before any governmental entity in which such governmental entity seeks to impose any legal restraint that, makes illegal or prohibits the consummation of the merger. Consequently, if one of the plaintiffs is successful in obtaining an injunction prohibiting Integrys or Wisconsin Energy from consummating the merger on the agreed-upon terms, then the injunction may prevent the merger from being completed within the expected timeframe, or at all. Furthermore, if the defendants are not able to resolve these lawsuits, the lawsuits could result in substantial costs to Wisconsin Energy and Integrys, including any costs associated with the indemnification of directors. The defense or settlement of any lawsuit or claim that remains unresolved at the time the merger is completed may adversely affect the combined company's business, financial condition or results of operations.

Table of Contents

Wisconsin Energy and Integrys may be unable to obtain the regulatory approvals required to complete the merger or, in order to do so, Wisconsin Energy and Integrys may be required to comply with material restrictions or conditions that may negatively affect the combined company after the merger is completed or cause them to abandon the merger.

        Completion of the merger is contingent upon, among other things, the receipt of all required regulatory approvals, which, in the case of Wisconsin Energy, consist of filings with and approvals of the NYSE, notice to, and the consent and approval of, the FERC, pre-approvals of license transfers with the FCC, notice to and approval of the PSCW, the ICC and the MPSC, and, if required or advisable, the MPUC and, in the case of Integrys, consist of filings with and approvals of the NYSE, notice to, and the consent and approval of, the FERC, pre-approvals of license transfers with the FCC, notice to and approval of the ICC and the MPSC, and, to the extent required, notice to and approval of the MPUC. The transaction also is subject to the notification, clearance and reporting requirements under the HSR Act. Wisconsin Energy and Integrys can provide no assurance that all required regulatory authorizations, approvals or consents will be obtained or that the authorizations, approvals or consents will not contain terms, conditions or restrictions that would be detrimental to the combined company after completion of the merger. See "The Merger—Regulatory Approvals Required for the Merger" beginning on page 101.

        The special meetings of Wisconsin Energy stockholders and Integrys shareholders at which the Merger-related proposals will be considered may take place before all of the required regulatory approvals have been obtained and before all conditions to such approvals, if any, are known. In this event, if the Merger-related proposals are approved, Wisconsin Energy and Integrys may subsequently agree to conditions without further seeking stockholder approval and/or shareholder approval, as the case may be, even if such conditions could have an adverse effect on Wisconsin Energy, Integrys or the combined company.

Delays in completing the merger may substantially reduce the expected benefits of the merger

        Satisfying the conditions to, and completion of, the merger may take longer than, and could cost more than, Wisconsin Energy and Integrys expect. Any delay in completing or any additional conditions imposed in order to complete the merger may materially adversely affect the benefits that Wisconsin Energy and Integrys expect to achieve from the merger and the integration of their respective businesses. In addition, each of Wisconsin Energy and Integrys may terminate the merger agreement if the merger is not completed by June 22, 2015, except that such date may be extended to December 22, 2015 if the only unsatisfied conditions to the completion of the merger are those regarding the receipt of required regulatory approvals.

Failure to complete the merger could negatively affect the share prices and the future businesses and financial results of Wisconsin Energy and Integrys.

        Completion of the merger is not assured and is subject to risks, including the risks that approval of the transaction by stockholders of Wisconsin Energy and shareholders of Integrys or by governmental agencies will not be obtained or that certain other closing conditions will not be satisfied. If the merger is not completed, the ongoing businesses and financial results of Wisconsin Energy or Integrys may be adversely affected and Wisconsin Energy and Integrys will be subject to several risks, including:

35


Table of Contents

        In addition, ten purported class action and/or derivative lawsuits have been filed against Integrys, members of the Integrys Board and Wisconsin Energy, seeking, among other things, an injunction prohibiting the consummation of the merger. While we believe these lawsuits are without merit, neither Wisconsin Energy nor Integrys can make any assurances as to the outcome of these lawsuits. See "The Merger—Litigation Related to the Merger" on page 112 and the above risk factor with the heading "—Pending litigation against Wisconsin Energy and Integrys could result in an injunction preventing completion of the merger, the payment of damages in the event the merger is completed and/or may adversely affect the combined company's business, financial condition or results of operations following the merger."

        The occurrence of any of these events individually or in combination could negatively affect the trading price of Wisconsin Energy common stock or Integrys common stock and the future businesses and financial results of each company.

The merger will combine two companies that are currently affected by developments in the regulated utility industry, including changes in regulation. A failure to adapt to the changing regulatory environment after the merger could adversely affect the stability of earnings and could result in erosion of the combined company's revenues and profits.

        Wisconsin Energy, Integrys and their respective subsidiaries are regulated in the United States at the federal level and in Wisconsin and Michigan. Integrys and its subsidiaries are also regulated in Illinois and Minnesota. As a result, the two companies have been and will continue to be impacted by legislative and regulatory developments in those jurisdictions, as will the combined company following the merger. After the merger, the combined company will be subject to extensive federal regulation, including environmental regulation, as well as subject to state and local regulation in all of the jurisdictions noted above.

The pro forma financial statements included in this joint proxy statement/prospectus are presented for illustrative purposes only and may not be an indication of the combined company's financial condition or results of operations following the merger.

        The pro forma financial statements contained in this joint proxy statement/prospectus are presented for illustrative purposes only, are based on various adjustments, assumptions and preliminary estimates and may not be an indication of the combined company's financial condition or results of operations following the merger for several reasons. See "Unaudited Pro Forma Condensed Combined Consolidated Financial Statements" beginning on page 154. The actual financial condition and results of operations of the combined company following the merger may not be consistent with, or evident from, these pro forma financial statements. In addition, the assumptions used in preparing the pro forma financial information may not prove to be accurate, and other factors may affect the combined company's financial condition or results of operations following the merger. Any potential decline in

36


Table of Contents

the combined company's financial condition or results of operations may cause significant variations in the stock price of the combined company.

The merger may not be accretive to earnings per share, which may negatively affect the market price of Wisconsin Energy's common stock.

        Wisconsin Energy currently anticipates that the merger will be accretive to earnings per share in the first full calendar year after closing. This expectation is based on preliminary estimates that are subject to change. Wisconsin Energy also could encounter additional transaction and integration-related costs, may fail to realize all of the benefits anticipated in the merger or be subject to other factors that affect preliminary estimates. Any of these factors could cause a decrease in Wisconsin Energy's earnings per share or decrease or delay the expected accretive effect of the merger and contribute to a decrease in the price of Wisconsin Energy's common stock.

The fairness opinions obtained by the Wisconsin Energy Board and the Integrys Board from their respective financial advisors will not reflect changes in circumstances between signing the merger agreement and the completion of the merger.

        Barclays, Wisconsin Energy's financial advisor, has delivered to the Wisconsin Energy Board a written opinion, dated as of June 22, 2014, as to the fairness, from a financial point of view, as of the date of the opinion, of the merger consideration to Wisconsin Energy.

        Lazard, Integrys' financial advisor, rendered its written opinion dated as of June 21, 2014, consistent with its oral opinion rendered on the same date, to the Integrys Board that, as of such date, and based upon and subject to the assumptions, procedures, factors, qualifications and limitations set forth therein, the merger consideration per share of Integrys common stock to be paid to the holders of Integrys' common stock (other than to (i) Integrys (as the holder of treasury shares but not in respect of the shares held by Integrys' rabbi trusts) and (ii) Wisconsin Energy or the merger subs, which are collectively referred to as excluded holders) in the merger was fair, from a financial point of view, to such holders.

        Neither the Wisconsin Energy Board nor the Integrys Board has obtained an updated fairness opinion as of the date of this joint proxy statement/prospectus from Barclays, Wisconsin Energy's financial advisor, or Lazard, Integrys' financial advisor.

        The opinions do not reflect changes that may occur or may have occurred after the date of the opinions, including changes in the operations and prospects of Wisconsin Energy or Integrys, general market and economic conditions and other factors that may be beyond the control of Wisconsin Energy or Integrys, and on which the fairness opinions were based, that may alter the value of Wisconsin Energy or Integrys or the prices of shares of Wisconsin Energy common stock or Integrys common stock by the time the merger is completed. The opinions do not speak as of the time the merger will be completed or as of any date other than the dates of such opinions. Because neither Wisconsin Energy nor Integrys anticipates asking its financial advisor to update its opinion, neither the opinion of Barclays nor the opinion of Lazard addresses the fairness of the merger consideration, from a financial point of view, at the time the merger is completed. The opinions are included as Annexes B and C to this joint proxy statement/prospectus. For a description of the opinion that the Wisconsin Energy Board received from Barclays and a summary of the material financial analyses it provided to the Wisconsin Energy Board in connection with rendering such opinion, please refer to "The Merger—Opinions of Financial Advisors—Opinion of Wisconsin Energy's Financial Advisor" beginning on page 64. For a description of the opinions that the Integrys Board received from Lazard and a summary of the material financial analyses it provided to the Integrys Board in connection with rendering such opinion, please see "The Merger—Opinions of Financial Advisors—Opinion of Integrys' Financial Advisor" beginning on page 74.

Table of Contents

Wisconsin Energy and Integrys will incur substantial transaction fees and costs in connection with the merger.

        Wisconsin Energy and Integrys expect to incur non-recurring expenses totaling approximately $60 million. Additional unanticipated costs may be incurred in the course of the integration of the businesses of Wisconsin Energy and Integrys. The companies cannot be certain that the elimination of duplicative costs or the realization of other efficiencies related to the integration of the two businesses will offset the transaction and integration costs in the near term, or at all.

Wisconsin Energy anticipates that it will need to obtain new financing in connection with the payment of the cash consideration in the merger.

        Wisconsin Energy expects to finance the cash consideration in the merger with new financing. There is no assurance that the new financing will be obtained on desired terms and within a desired timeframe or will not contain terms, conditions or restrictions that would be detrimental to the combined company after the completion of the merger. There are no financing conditions to the merger, and the merger is not conditioned upon obtaining the financing to fund the cash consideration of the merger. Accordingly, Wisconsin Energy may be required to complete the merger whether or not debt financing is available at all or on acceptable terms.

Certain directors and executive officers of Wisconsin Energy and Integrys have interests in the merger that are different from, or in addition to, those of other Wisconsin Energy stockholders and Integrys shareholders, which could have influenced their decisions to support or approve the merger.

        In considering whether to approve the proposals at the special meetings, Wisconsin Energy stockholders and Integrys shareholders should recognize that certain directors and executive officers of Wisconsin Energy and Integrys have interests in the merger that differ from, or that are in addition to, their interests as stockholders of Wisconsin Energy and shareholders of Integrys. These interests include, among others, ownership interests in the combined company, continued service as a director or an executive officer of the combined company, and/or the accelerated vesting of certain equity awards and/or severance benefits as a result of termination of employment in connection with the merger. These interests, among others, may influence the directors and executive officers of Wisconsin Energy and/or Integrys to approve and/or recommend Merger-Related proposals. The Wisconsin Energy Board and the Integrys Board were aware of and considered these interests at the time each approved the merger agreement. See "The Merger—Interests of Directors and Executive Officers in the Merger" beginning on page 89.

Uncertainties associated with the merger may cause a loss of management personnel and other key employees of Wisconsin Energy or Integrys which could adversely affect the future business and operations of the combined company following the merger.

        Wisconsin Energy and Integrys are dependent on the experience and industry knowledge of their officers and other key employees to execute their business plans. The combined company's success after the merger will depend in part upon its ability to retain key management personnel and other key employees of Wisconsin Energy and Integrys. Current and prospective employees of Wisconsin Energy and Integrys may experience uncertainty about their future roles with the combined company following the merger, which may materially adversely affect the ability of each of Wisconsin Energy and Integrys to attract and retain key personnel during the pendency of the merger. Accordingly, no assurance can be given that the combined company will be able to retain key management personnel and other key employees of Wisconsin Energy and Integrys.

The combined company's hedging activities may not be fully protected from fluctuations in commodity prices and cannot eliminate the risks associated with these activities.

        Wisconsin Energy currently enters into hedging agreements, including contracts to purchase or sell commodities at future dates and at fixed prices, in order to manage the commodity price risks inherent in its power generation operations. Integrys currently engages in hedging activities to manage the risks associated with volatility in prices for electricity, fuel and emissions allowances. Wisconsin Energy and Integrys expect that the combined company will use appropriate hedging strategies to manage this risk, including opportunistically hedging over multiple year periods to reduce the variability in realized gross margin from its expected generation. The combined company cannot provide assurance that these activities will be successful in managing its price risks or that they will not result in net losses as a result of future volatility in electricity, fuel and emissions markets. Actual power prices and fuel costs may differ from the combined company's expectations.

        Furthermore, the hedging procedures that the combined company will have in place may not always be followed or may not always work as planned. If any of the combined company's employees were able to engage in unauthorized hedging and related activities, it could result in significant penalties and financial losses. As a result of these and other factors, we cannot predict the outcome that risk management decisions may have on the business, operating results or financial position of the combined company.

The shares of Wisconsin Energy common stock to be received by Integrys shareholders as a result of the merger will have different rights from the shares of Integrys common stock.

        Upon completion of the merger, Integrys shareholders will become Wisconsin Energy stockholders and their rights as stockholders will be governed by Wisconsin Energy's articles of incorporation and bylaws. Certain of the rights associated with Wisconsin Energy common stock are different from the rights associated with Integrys common stock. Please see "Comparison of Shareholder Rights" beginning on page 166 for a discussion of the different rights associated with Wisconsin Energy common stock.


Risks Relating to Wisconsin Energy and Integrys

        Wisconsin Energy and Integrys are, and will continue to be, subject to the risks described in the following periodic reports, each of which is incorporated by reference into this joint proxy statement/prospectus:

THE MERGER

        The following is a discussion of the merger and the material terms of the merger agreement between Wisconsin Energy and Integrys. You are urged to read carefully the merger agreement in its entirety, a copy of which is attached as Annex A to this joint proxy statement/prospectus and incorporated by reference herein.


Background of the Merger

        The Wisconsin Energy Board and senior management regularly review and evaluate the possibility of pursuing various business combination transactions as part of their ongoing efforts to strengthen their business and enhance stockholder value, taking into account economic, competitive and other conditions, as well as their acquisition criteria. As part of this process, from time to time, Wisconsin Energy senior management has had conversations and communications with various investment banking firms regarding potential transaction opportunities and, from time to time, has had conversations with representatives of other companies regarding a potential business combination transaction, though none of these conversations, other than those with Integrys, resulted in significant discussions.

        The Integrys Board and senior management regularly review and evaluate the possibility of pursuing various business combination transactions as part of their ongoing efforts to strengthen their business and enhance shareholder value, taking into account economic, competitive and other conditions, as well as their acquisition criteria. Integrys' goal is to create long-term value for shareholders and customers through growth in its core regulated businesses. As an essential component of this strategy, the Integrys Board and senior management continuously assess existing assets, the acquisition of assets and contractual commitments to complement Integrys' existing business and strategy. As part of this process, from time to time, Integrys senior management has had conversations and communications with various investment banking firms regarding potential transaction opportunities. In particular, Lazard has been engaged by Integrys since September 2011 to assist Integrys with its strategic planning and to periodically review with the Integrys Board potential strategic alternatives.

        From time to time, Integrys has also had conversations with representatives of other companies regarding potential business combination transactions, though none of these conversations, prior to the discussions on the merger, resulted in significant discussions.

        During the third and fourth quarters of 2013, Wisconsin Energy senior management, together with representatives of Barclays, reviewed various financial analyses and related information with respect to multiple potential transaction opportunities, including a potential acquisition of Integrys. Throughout the third and fourth quarters of 2013, those financial analyses were periodically updated and revised based on publicly available information.

        On December 5, 2013, at a regularly scheduled meeting of the Wisconsin Energy Board, Mr. Gale E. Klappa, Chairman and Chief Executive Officer of Wisconsin Energy, discussed with the Board a potential acquisition of Integrys. During the meeting, Mr. Klappa, along with Mr. Allen L. Leverett, President of Wisconsin Energy, reviewed with the Board the preliminary evaluation that had been done to date on a potential acquisition of Integrys, based only on publicly available information. Messrs. Klappa and Leverett described the financial merits of and strategic rationale for a potential transaction with Integrys. Following discussion at the meeting, the Wisconsin Energy Board authorized management to explore an acquisition of Integrys and authorized Mr. Klappa to discuss the possibility of a potential transaction with his counterpart at Integrys.

        On December 9, 2013, Mr. Klappa telephoned Mr. Charles A. Schrock, Chairman and Chief Executive Officer of Integrys, to request a meeting with him. During this discussion, Mr. Klappa briefly described to Mr. Schrock Wisconsin Energy's general interest in exploring a possible transaction with

40


Table of Contents

Integrys. Mr. Schrock also informed Lazard about Wisconsin Energy's interest and confirmed that Lazard was free from any conflicts of interest that would impair Lazard's ability to advise Integrys with respect to any such potential transaction. Given Lazard's familiarity with Integrys and the industry landscape, Integrys senior management determined to request the Integrys Board to engage Lazard as financial advisor in connection with the potential transaction with Wisconsin Energy, subject to negotiation of an acceptable fee arrangement.

        On December 12, 2013, the Integrys Board held a regularly scheduled meeting at which representatives of Lazard were present. At the meeting, the Integrys Board met in executive session with Mr. Schrock present, during which Mr. Schrock informed the Integrys Board of Wisconsin Energy's general interest in exploring a possible transaction with Integrys.

        On December 18, 2013, Messrs. Klappa and Schrock met for dinner. At this initial meeting, Mr. Klappa described to Mr. Schrock Wisconsin Energy's view of the possible strategic benefits of an acquisition of Integrys by Wisconsin Energy. Mr. Klappa described to Mr. Schrock the criteria by which Wisconsin Energy evaluates potential acquisitions. Messrs. Klappa and Schrock further discussed Integrys' projected growth plan, a possible transaction structure and the regulatory approval process for and implications of a transaction. Mr. Schrock agreed to consider the discussion further and provide a preliminary response to Mr. Klappa within several weeks, and emphasized that ultimately the Integrys Board would have the decision-making authority with respect to any strategic transaction.

        On January 15, 2014, Mr. Schrock telephoned Mr. Klappa in response to their discussion at their December 18, 2013 dinner meeting. Mr. Schrock stated that he and the Integrys Board would evaluate a potential transaction and respond to Wisconsin Energy after analysis and discussion, but did not provide a specific timeframe for a response. He expressed an interest in maintaining a dialogue with Mr. Klappa as they each considered a possible transaction further, although they did not discuss a timeline or process for such evaluation, nor did they determine when they would next speak.

        On January 16, 2014, the Wisconsin Energy Board held a regularly scheduled meeting. At the meeting, Mr. Klappa provided the Wisconsin Energy Board with an update on his discussions with Mr. Schrock. The Wisconsin Energy Board and management engaged in additional discussion regarding the strategic rationale and benefits of a possible transaction with Integrys, as well as potential risks, and authorized management to continue to evaluate a potential transaction and engage in further discussions with Integrys.

        On January 16, 2014, Wisconsin Energy contacted Skadden to serve as legal counsel in connection with a potential transaction with Integrys.

        On January 20, 2014, Integrys issued a press release announcing that Integrys had entered into a definitive agreement with Balfour Beatty Infrastructure Partners LP, or BBIP, to sell 100 percent of the stock of Upper Peninsula Power Company, or UPPCO, to BBIP.

        On January 22, 2014, Mr. Schrock telephoned Mr. Klappa to discuss the January 20, 2014 UPPCO sale announcement. Mr. Schrock stated that the pending sale of UPPCO would not alter Integrys' evaluation of a potential transaction with Wisconsin Energy.

        On February 13, 2014, the Integrys Board held a regularly scheduled meeting at which representatives of Lazard were present. Mr. Schrock summarized his communications with Mr. Klappa since December 18, 2013. A representative of Lazard provided an overview of Integrys' management plan and potential strategic alternatives that could complement Integrys' long-term financial and strategic plan. A representative of Lazard reviewed selected potential strategic alternatives with potential counterparties, which included four strategic buyers, three potential merger parties and one potential strategic target. The representative also discussed a potential take private alternative. The representative discussed with the Integrys Board Lazard's preliminary analysis of a potential transaction with each such counterparty and the industrial logic of a potential transaction. The representative of

41


Table of Contents

Lazard also reviewed Lazard's views on the likely strategic interest of each such counterparty of a potential M&A transaction, in general and specifically with respect to Integrys, as well as the likely ability of such counterparty to consummate a potential transaction and the perceived likelihood that any such counterparty would approach Integrys with a proposal offering better value than Wisconsin Energy's proposal. The Integrys Board discussed the likelihood of any other of the identified potential buyers making an offer for Integrys that would represent more value to Integrys' shareholders than Wisconsin Energy's proposal and discussed the strong strategic rationale of a transaction with Wisconsin Energy. After discussion, during which the Integrys Board also considered the risk of a leak if any of the potential buyers were contacted and the risk to Wisconsin Energy's proposal posed by that leak, the Integrys Board determined that it would defer a decision about whether to contact other potential counterparties until it had more clarity with respect to Wisconsin Energy's proposal.

        On February 20, 2014, Mr. Schrock telephoned Mr. Klappa to request a meeting to further discuss a potential transaction. Messrs. Klappa and Schrock agreed to a meeting on Tuesday, March 4, 2014 in Milwaukee, Wisconsin.

        On March 1, 2014, the Integrys Board held a special meeting at which representatives of Lazard and Foley & Lardner LLP, referred to as Foley, were present. A representative of Foley provided an overview of certain matters under Wisconsin law, including an overview of director and officer fiduciary duties and considerations in strategic transactions. Senior management reviewed Integrys' financial and strategic plan as a stand-alone entity and Wisconsin Energy's strategic plan. A representative of Lazard discussed Lazard's preliminary analysis of Integrys' financial and strategic plan, preliminary valuation and options relating to a potential strategic transaction. Mr. Schrock reviewed management's observations of Lazard's preliminary analysis and discussed constituent considerations, including customer, employee and regulatory concerns. The Integrys Board discussed the Integrys financial and strategic plan, potential counterparties for strategic transactions and alternatives that would be in the best interests of Integrys shareholders. At this meeting, the Integrys Board resolved to formally engage Lazard to provide advisory services to Integrys in regard to potential strategic transactions.

        On March 4, 2014, Messrs. Klappa and Schrock met. At the meeting, Messrs. Klappa and Schrock mutually agreed to proceed to evaluate a potential acquisition of Integrys by Wisconsin Energy. They agreed to instruct their respective management teams to enter into a mutual confidentiality agreement and proceed to exchange non-public information. They further agreed to establish a schedule for conducting management presentations to be given by each party. They discussed retention of financial advisors (with Mr. Klappa identifying Barclays, though Barclays was not formally engaged until April 25, 2014, and Mr. Schrock identifying Lazard) and discussed allowing their respective financial advisors to exchange information. Messrs. Klappa and Schrock discussed targeting the end of June 2014 to complete the evaluation and discussions of a potential transaction. Messrs. Schrock and Klappa agreed that the next step would be for Wisconsin Energy to provide a non-binding indicative offer letter to Integrys that would address key issues such as a preliminary price and form of consideration, regulatory strategy and certain governance issues, including management of a combined company and headquarters location. There was no discussion of any continuing role for any of the senior management of Integrys, including Mr. Schrock. Mr. Schrock requested that, if Wisconsin Energy determined to make a non-binding indicative offer, it do so in a letter delivered to Integrys by mid-April, 2014.

        On March 6, 2014, representatives of Integrys sent a draft mutual confidentiality agreement to representatives of Wisconsin Energy, which contained customary standstill provisions applicable to both companies. Representatives of Wisconsin Energy provided comments to representatives of Integrys shortly thereafter. On that same day, Wisconsin Energy retained the firm of Economists Incorporated to assist in the evaluation of federal regulatory implications of the proposed transaction (and subsequently retained the firm of Compass Lexecon to further assist in the evaluation).

        Later on March 6, 2014, the Wisconsin Energy Board held a telephonic special meeting. Mr. Klappa discussed the details of his most recent meeting with Mr. Schrock and described the agreed upon process and timeline for further consideration of the potential acquisition. Mr. Klappa discussed with the Wisconsin Energy Board developing a non-binding indicative offer letter that would address, among other things, preliminary price and form of consideration, management of the combined company and headquarters location. The Wisconsin Energy Board engaged in discussion of the proposed process and timeline and the issues to be addressed in the non-binding offer letter and related implications, and authorized management to engage in further evaluation and discussions in accordance with the agreed process and timeline.

        On March 7, 2014, Wisconsin Energy and Integrys executed the mutual confidentiality agreement, with customary standstill provisions applicable to both companies to remain in effect for one year. After execution of the mutual confidentiality agreement, the parties began to exchange certain non-public information through an electronic data room site and in person and telephonic meetings between members of each company's senior management teams, representatives of Barclays and Lazard and each company's legal representatives. In addition, Mr. Schrock informed Mr. Klappa that since late 2013 Integrys has been planning the divestiture of certain of its non-regulated businesses and would continue to pursue this divestiture.

        On March 15, 2014, representatives of Barclays and representatives of Lazard participated in a teleconference during which they discussed the matters to be addressed at an upcoming meeting between senior management teams of Wisconsin Energy and Integrys to be held on March 28, 2014.

        On March 21, 2014, as a follow-up to the discussions between Messrs. Klappa and Schrock on March 4, 2014, representatives of Lazard sent to representatives of Barclays an "Indicative Offer Checklist" that identified information to be included in a non-binding indication of interest letter, including a non-binding indication of price to be paid per share of Integrys and the form such consideration would take, a description of key assumptions underlying such consideration, a description of pro forma dividend policy, information regarding the regulatory approval process, information regarding board approvals to which any offer would be subject and confirmation that an indicative offer has been approved by the Wisconsin Energy Board, a list of significant business questions that are important to Wisconsin Energy's final determination of price or that could materially impact price or Wisconsin Energy's ability to purchase Integrys, key governance terms such as pro forma board representation, pro forma management team composition, proposed headquarters location and other key governance terms, and an expected timeline to signing a definitive agreement. The checklist further requested that the non-binding offer be delivered to Integrys on April 21, 2014.

        On March 26, 2014, members of Wisconsin Energy's and Integrys' senior management teams, along with their respective financial advisors, participated in a teleconference during which they discussed financial models for both Wisconsin Energy and Integrys in anticipation of the management presentation meeting to be held on March 28, 2014.

        On March 28, 2014, the senior management teams of Wisconsin Energy and Integrys, together with their respective financial advisors, met. At the meeting, the parties shared non-public information regarding their respective businesses, including company overviews and information regarding their respective strategic plans and historical performance, upcoming rate cases, labor relations, pending legal matters and debt profiles. The parties also discussed their respective views on the merits of an acquisition of Integrys by Wisconsin Energy.

        On April 4, 2014, representatives of Barclays and representatives of Lazard held a teleconference during which they discussed their respective views regarding the valuation of Integrys.

        On April 7, 2014, members of senior management of Wisconsin Energy and Integrys, together with their respective financial advisors, met to discuss Integrys' non-regulated businesses and its plan to

divest. The discussion related to Integrys Energy Services, Inc., a subsidiary of Integrys referred to as IES, and its business segments involved in marketing electricity and natural gas in various retail markets, referred to as the IES Retail Business, and investing in energy assets with renewable attributes, referred to as the IES Solar Business, as well as to Integrys' compressed natural gas business.

        On April 8, 2014, members of senior management of Wisconsin Energy and Integrys, together with their respective financial advisors, held a teleconference in which they discussed initial expectations relating to Wisconsin Energy's non-binding indicative offer.

        On April 9, 2014, the Integrys Board held a special telephonic meeting, with representatives of Lazard present. Mr. Schrock reviewed the status of discussions with Wisconsin Energy and described the continued evaluation of additional potential counterparties by Integrys senior management and its advisors. The Integrys Board reviewed the proposed engagement of outside counsel and resolved to engage Cravath, Swaine & Moore LLP, referred to as Cravath, Foley and other local counsel as needed to support Integrys' evaluation of strategic alternatives.

        On April 16, 2014. Messrs. Klappa and Schrock spoke over the telephone regarding the status of discussions to date and a timeline and process for continued evaluation of a potential transaction. Mr. Klappa notified Mr. Schrock that the Wisconsin Energy Board would meet the following day and engage in an extensive discussion of a proposed acquisition of Integrys, including review of the terms for a non-binding indication of interest letter to be delivered to Integrys shortly thereafter. Messrs. Klappa and Schrock discussed a timeline for continuing due diligence review and set a target date of April 23, 2014 or April 24, 2014 to meet again for further discussion.

        On April 17, 2014, the Wisconsin Energy Board held a regularly scheduled meeting, with representatives of Barclays present. At the meeting, Mr. Klappa reviewed the status of discussions with Integrys. Mr. Leverett reviewed with the Wisconsin Energy Board proposed terms to be set forth in a non-binding indication of interest letter to be delivered to Integrys, including preliminary price and form of consideration and certain governance issues such as board representation, management of the combined company and headquarters location. At the meeting, Mr. Leverett and representatives of Barclays reviewed various financial aspects of a proposed transaction and discussed various combinations of cash and equity consideration in relation to their impact on the satisfaction of Wisconsin Energy's acquisition criteria. Following discussion of the possible transaction, including the proposed terms outlined by Messrs. Klappa and Leverett and associated risks and benefits of an acquisition of Integrys, the Wisconsin Energy Board authorized management to deliver the non-binding indication of interest letter to Integrys using a combination of cash and equity consideration that would result in the satisfaction of Wisconsin Energy's acquisition criteria. The Wisconsin Energy Board also met in executive session with Mr. Klappa present to further discuss issues of leadership and governance in connection with the proposed acquisition of Integrys.

        On April 23, 2014, Messrs. Klappa and Schrock met. At the meeting, Mr. Klappa presented Mr. Schrock with a non-binding indication of interest letter. The letter set forth a non-binding proposal for the acquisition of Integrys by Wisconsin Energy. The letter addressed terms including a proposed amount and structure of the consideration to be paid to Integrys shareholders, the post-closing dividend policy, conditions to the proposal, general scope of due diligence, post-closing management and board composition and headquarters location. Under the April 23, 2014 letter, Integrys shareholders would receive $71.68 per share of Integrys common stock, comprised of base consideration of $54.90 in Wisconsin Energy common stock (representing a fixed exchange ratio of 1.142 shares of Wisconsin Energy common stock for each share of Integrys common stock) and $12.05 in cash, and a special dividend of the after-tax net proceeds and certain balance sheet adjustments from the sale of IES (which was assumed to occur prior to the closing of the transaction) expected to be $4.73 per share. The letter confirmed that the offer would not be subject to a financing contingency, but that Wisconsin

44


Table of Contents

Energy would engage with credit rating agencies with respect to the structure of the potential transaction to ensure that financing would be structured to allow Wisconsin Energy to minimize any changes to its credit ratings following the closing of the proposed transaction. The letter did not include any offers of positions with the combined company for members of the Integrys senior management team. The letter contemplated that, following the closing of the transaction, the Wisconsin Energy Board would be expanded so as to include appropriate representation from the existing Integrys Board of Directors, without specifying the number or identity of the Integrys directors that would join the Wisconsin Energy Board. The letter also stated that the non-binding proposal was subject to execution of an exclusivity agreement by the parties. Messrs. Klappa and Schrock discussed Wisconsin Energy's views with respect to valuation, as well as the proposed terms set forth in the non-binding letter. Mr. Klappa also discussed with Mr. Schrock his preliminary views on regulatory strategy.

        During the period from April 23, 2014 to April 30, 2014, representatives of Barclays and representatives of Lazard had numerous discussions to clarify the proposed amount and structure of the consideration to be paid to Integrys shareholders, including replacing the special dividend to Integrys shareholders of the proceeds from a sale of IES with a different form of consideration.

        On April 29, 2014, the Integrys Board held a special telephonic meeting at which representatives of Lazard and Cravath were present. Mr. Schrock reviewed the status of discussions with Wisconsin Energy. A representative of Lazard described the non-binding indicative offer that Wisconsin Energy delivered to Integrys on April 23, 2014. The Integrys Board and Integrys' advisors also discussed the benefits and risks of the proposed terms and items of clarification to discuss with Wisconsin Energy. In particular, the Integrys Board discussed with the advisors the benefits and risks of entering into an exclusivity agreement with Wisconsin Energy and determined that it would not be in Integrys' interest to enter into such an agreement at that time.

        On April 30, 2014, Mr. Schrock telephoned Mr. Klappa to request a revised proposal from Wisconsin Energy that would provide for two alternative consideration structures to address the contingent nature of the sale of IES. Mr. Klappa committed to evaluate an alternative consideration structure and provide a response to Mr. Schrock, though he did not provide a timeline for any such response. Mr. Schrock also informed Mr. Klappa that Integrys was not prepared to enter into an exclusivity agreement with Wisconsin Energy at that time.

        On May 2, 2014, the Wisconsin Energy Board held a regularly scheduled meeting at which Messrs. Klappa and Leverett provided an update on discussions with Integrys and evaluation of a possible acquisition. Senior management of Wisconsin Energy discussed Mr. Schrock's request for an alternative contingent consideration component relating to the sale of IES. After discussion, the Wisconsin Energy Board authorized management to proceed with proposing an alternative consideration structure to Integrys through an updated non-binding indication of interest letter, which contained the same terms as the April 23, 2014 letter, other than with respect to the proposal on alternative consideration. As requested by Mr. Schrock, the proposal on alternative consideration involved two alternative consideration structures.

        On May 7, 2014, at the direction of Messrs. Klappa and Schrock, members of the senior management of Wisconsin Energy and Integrys held a teleconference to review and discuss the updated non-binding indication of interest letter, which provided for two alternative structures of consideration to be paid to Integrys shareholders and updated the proposed valuation based on current respective share prices. Under the first alternative structure, Integrys shareholders would receive $71.62 per share of Integrys common stock, comprised of base consideration of $54.84 in Wisconsin Energy common stock (representing a fixed exchange ratio of 1.142 shares of Wisconsin Energy common stock for each share of Integrys common stock) and $12.05 in cash, and a special dividend of the after-tax net proceeds and certain balance sheet adjustments from the IES sale expected to be $4.73 per share. Under the second alternative structure, Integrys shareholders would receive the same base

consideration, an additional $3.00 per share in cash consideration, and contingent consideration equal to the amount, if any, by which the per share after tax net proceeds from the IES sale exceeded $3.00. Later that same day, Wisconsin Energy provided the updated letter to Integrys. The letter was otherwise substantially similar in all respects to the non-binding indication of interest letter delivered April 23, 2014, including being subject to execution of an exclusivity agreement by the parties.

        On May 7, 2014, representatives of Barclays and representatives of Lazard discussed the updated non-binding indication of interest letter that Wisconsin Energy had provided to Integrys earlier that day.

        On May 9, 2014, the Integrys Board held a special meeting at which representatives of Lazard, Cravath and Foley were present. Mr. Schrock reviewed the status of discussions with Wisconsin Energy. Senior management reviewed the status of negotiations to sell the IES Retail Business. The Integrys Board discussed the timing of the sale of the IES Retail Business and the timing of negotiations with Wisconsin Energy. The Integrys Board discussed suspending negotiations with Wisconsin Energy until the sale of the IES Retail Business was complete, but concluded that it was appropriate to continue with both processes and to consider whether appropriate consideration was offered by Wisconsin Energy for Integrys in light of the value of the IES Retail Business. A representative of Lazard described the revised non-binding indicative offer that Wisconsin Energy delivered to Integrys on May 7, 2014, which included two alternative structures of consideration. The Integrys Board and Integrys' advisors discussed the benefits and risks of the proposed terms and items of clarification to discuss with Wisconsin Energy. They also compared the initial non-binding indicative offer with the revised non-binding indicative offer, compared Integrys' stand-alone plan with Wisconsin Energy's plan and discussed the timing of the sale of the IES Retail Business. The Integrys Board and Integrys' advisors also discussed other potential strategic alternatives Integrys might pursue, including strategic transactions with other counterparties. The Integrys Board discussed the request for exclusivity included in the revised non-binding indicative offer and the benefits and risks of agreeing to such request. The Integrys Board also directed management to seek clarification of certain proposed terms of the revised non-binding indicative offer.

        On May 12, 2014, representatives of Barclays and representatives of Lazard participated in a teleconference during which they discussed and clarified the revised non-binding indicative offer, including the merger consideration and alternative structures of consideration. Representatives of Lazard confirmed to representatives of Barclays that Integrys intended to retain the IES Solar Business and sell the IES Retail Business. Representatives of Lazard asked the representatives of Barclays to consider what adjustment to the contingent consideration structure alternative would be necessary in the event of a sale by Integrys of the IES Retail Business only.

        On May 12, 2014, senior management of Wisconsin Energy and Integrys met to discuss the credit implications of a proposed transaction.

        On May 13, 2014, Messrs. Klappa and Schrock spoke by telephone. Mr. Schrock advised Mr. Klappa that he would be discussing the updated non-binding indication of interest letter with the Integrys Board at their May 15, 2014 meeting.

        On May 15, 2014, the Integrys Board held a regular scheduled meeting at which representatives of Lazard, Cravath and Foley were present. A representative of Lazard reviewed Lazard's revised analysis of Integrys' management plan, Wisconsin Energy's long-term plan and Wisconsin Energy's revised non-binding indicative offer. A representative of Lazard reviewed Lazard's preliminary pro forma financial analysis of a combined Integrys and Wisconsin Energy company and compared the revised non-binding indicative offer with precedent transactions. The Integrys Board discussed the request for exclusivity included in the revised non-binding indicative offer and the benefits and risks of agreeing to such request. The Integrys Board and Integrys' advisors also discussed potential alternative strategic transactions with other counterparties. A representative from Lazard discussed with the Integrys Board

46


Table of Contents

Lazard's analysis of the other potential counterparties. The Integrys Board discussed the likelihood of any other of the identified potential buyers making an offer for Integrys that would represent more value to Integrys' shareholders than Wisconsin Energy's proposal, as well as the risk of a leak if any of the potential buyers were contacted and the risk to Wisconsin Energy's proposal posed by that leak. A representative of Lazard reviewed with the Integrys Board the universe of potential buyers that might have the strategic interest in pursuing, and the financial capability to pursue, a potential acquisition of Integrys and gave Lazard's preliminary observation that it was highly unlikely that any such third parties would propose a transaction exceeding the value proposed by Wisconsin Energy at that time. The Integrys Board further discussed the strong strategic rationale for a transaction with Wisconsin Energy and the need to receive a strong premium on top of Integrys' financial base plan as a stand-alone entity. After discussion, the Integrys Board determined not to actively seek proposals from other potential transaction counterparties at that time, but determined that Integrys would not enter into an exclusivity agreement with Wisconsin Energy. The Integrys Board authorized Mr. Schrock and Integrys management to proceed negotiating a definitive merger agreement with Wisconsin Energy. The Integrys Board also resolved to establish a committee consisting of Mr. Budney, Mr. Jones and Ms. Keller Koeppel (the "Transaction Committee") to oversee and work together with management in connection with Integrys' exploration of a strategic transaction with Wisconsin Energy. The Transaction Committee was established to facilitate close participation of members of the Integrys Board in the negotiation process, but was not authorized by the Board to make any decisions with respect to the proposed transaction.

        On May 16, 2014, Mr. Schrock telephoned Mr. Klappa and reported that the Integrys Board had discussed the potential transaction and authorized management to proceed to negotiate a definitive merger agreement. During this and a second call that same day, Messrs. Klappa and Schrock agreed on a process for moving forward with necessary additional due diligence and negotiations of a definitive agreement to be conducted over a 30 to 40 day period. Mr. Schrock notified Mr. Klappa that Integrys was not prepared to execute an exclusivity agreement with Wisconsin Energy.

        Later on May 16, 2014, Mr. Klappa provided an update to the Wisconsin Energy Board summarizing his conversations with Mr. Schrock from earlier in the day.

        On May 20, 2014, representatives of Barclays and representatives of Lazard participated in a teleconference during which they discussed the amount and structure of the merger consideration, including the exchange ratio and percentages of cash and stock portions of the merger consideration.

        On May 22, 2014, the Integrys Transaction Committee held a special telephonic meeting to review the status of discussions with Wisconsin Energy. Mr. Schrock discussed with the Transaction Committee key activities related to the potential transaction.

        On May 23, 2014, Mr. Klappa provided another update to the Wisconsin Energy Board summarizing progress on the due diligence review that had been conducted on Integrys to date, as well as an update on the ongoing regulatory analysis being conducted by Economists Incorporated, Compass Lexecon and Skadden. Mr. Klappa further notified the Board of a schedule for review and negotiation of a draft merger agreement.

        During the period from May 16 to May 31, 2014, members of the senior management teams of Wisconsin Energy and Integrys and their respective legal and financial advisors held numerous discussions and continued to engage in mutual due diligence.

        On May 27, 2014, the Integrys Board held a special telephonic meeting at which representatives of Lazard and Cravath were present.

Integrys directors had considered and discussed various matters relating to the proposed transaction, including valuation of Integrys, the proposed termination fee, the treatment of equity awards, the ongoing commitment to community of the combined company, the number of Integrys directors to be appointed to the board of the combined company, the size of the retention pool and the status of the sale of the IES Retail Business.

Mr. Klappa notified the Wisconsin Energy Board that the parties had agreed, subject to approval of the Wisconsin Energy Board, that the corporate headquarters and principal executive offices of Wisconsin Energy would be located in metropolitan Milwaukee, Wisconsin, with operational headquarters in Chicago, Illinois, Milwaukee and Green Bay, Wisconsin. The Wisconsin Energy Board and senior management also discussed changing the name of Wisconsin Energy to "WEC Energy Group, Inc." upon completion of the merger, in order to reflect the combined company's broader geographic presence, and decided that it made sense to do so. A representative of Skadden described for the Wisconsin Energy Board the approvals that would be required to complete the proposed transaction, including regulatory approvals and the approvals of the stockholders of both Wisconsin Energy and Integrys, reviewed with the Wisconsin Energy Board the terms of a proposed merger agreement, including the significant outstanding issues, and summarized the Wisconsin Energy Board's fiduciary duties. Messrs. Klappa and Leverett reviewed with the Wisconsin Energy Board the risks associated with the transaction, including risks relating to financing of the cash portion of the merger consideration (including describing the receipt by Wisconsin Energy of a letter from Barclays indicating that Barclays was "highly confident" in its ability to secure financing) and risks relating to the regulatory review and approval process of the transaction and the associated conditions to closing of the transaction. Representatives from Barclays reviewed with the Wisconsin Energy Board Barclays' financial analysis performed in connection with the proposed merger. After considering and discussing the foregoing, the Wisconsin Energy Board authorized management to continue negotiations with Integrys toward finalizing the outstanding terms of the merger agreement, subject to final approval of the Wisconsin Energy Board.

50

consideration and 1.128 shares of Wisconsin Energy common stock for every share of Integrys common stock, representing total consideration of $69.60 per share of Integrys common stock. A representative of Lazard discussed Lazard's updated analysis of the proposal, reviewed the premium implied by the proposal and compared the proposal to precedent transactions. Mr. Schrock then described the status of negotiations of the merger agreement. Integrys senior management reviewed the status of the due diligence process with Wisconsin Energy. A representative of Cravath summarized the key terms of the merger agreement and reviewed outstanding issues in the merger agreement negotiations, including the size of the termination fee, the allocation of regulatory risk and the treatment of equity awards. Mr. Schrock, the Integrys Board and senior management discussed constituent considerations, including customer, employee and regulatory concerns, and the need to maintain charitable commitments and community presence. After considering and discussing the foregoing, the Integrys Board authorized management to continue negotiations with Wisconsin Energy toward finalizing the outstanding terms of the merger agreement, subject to final approval of the Integrys Board.

        Throughout the day on June 20, 2014 and June 21, 2014, representatives of Wisconsin Energy, Integrys, Skadden and Cravath engaged in discussions and negotiations of the remaining outstanding issues in the merger agreement and related disclosure schedules and exhibits, and exchanged numerous drafts.

        On June 21, 2014, the Integrys Board held a special telephonic meeting for the purpose of considering the proposed transaction with Wisconsin Energy. Members of senior management of Integrys and representatives of Lazard, Cravath and Foley were present at the meeting. Mr. Schrock reviewed the status of negotiations with Wisconsin Energy on a definitive merger agreement. A representative of Cravath reviewed with the Board the material changes to the proposed merger agreement since the last meeting of the Integrys Board. A representative of Lazard reviewed the terms of Wisconsin Energy's latest proposal, which included $18.58 in cash consideration and 1.128 shares of Wisconsin Energy common stock for every share of Integrys common stock representing total consideration of $71.47 per share of Integrys common stock. A representative of Lazard reviewed with the Integrys Board the universe of potential buyers that might have the strategic interest in pursuing, and the financial capability to pursue, a potential acquisition of Integrys and observed that it was highly unlikely that any such third parties would propose a transaction exceeding the value proposed by Wisconsin Energy at that time. A representative of Lazard stated that, based upon and subject to the qualifications and conditions set forth in Lazard's written fairness opinion, Lazard was of the opinion that, as of the date thereof, the consideration to be paid to holders of Integrys common stock (other than excluded holders, as defined in the fairness opinion) in the proposal was fair, from a financial point of view, to such holders. After considering and discussing the foregoing and the proposed terms of the merger agreement, and taking into consideration the factors described under "—Recommendation of the Integrys Board of Directors and Integrys' Reasons for the Merger" and "—Opinions of Financial Advisors—Opinion of Integrys' Financial Advisor," the Integrys Board unanimously (i) approved the merger agreement and declared that the mergers and the other transactions contemplated thereby are in the best interests of Integrys and its shareholders, (ii) recommended that Integrys shareholders vote "FOR" the merger agreement and directed that the merger agreement be submitted to Integrys shareholders for approval at a duly held meeting of such shareholders for such purpose, and (iii) authorized officers of Integrys to execute transactions contemplated by the merger agreement and make required regulatory and other filings.

        Following the meeting of the Integrys Board, Mr. Schrock telephoned Mr. Klappa and informed him of the action taken by the Integrys Board.

        On June 22, 2014, the Wisconsin Energy Board held a telephonic special meeting to consider the proposed transaction with Integrys, with senior management of Wisconsin Energy and representatives of Barclays and Skadden in attendance.

51


Table of Contents

subsequently confirmed in writing June 22, 2014), that as of the date of the opinion and subject to and based upon the factors, procedures, assumptions, qualifications and limitations discussed in the opinion, the merger consideration to be paid in the merger was fair, from a financial point of view, to Wisconsin Energy. Wisconsin Energy senior management and a representative of Skadden addressed director questions regarding resolution of outstanding issues in the merger agreement and various due diligence matters. After considering and discussing the foregoing and the proposed terms of the merger agreement, and taking into consideration the factors described under "—Recommendation of the Wisconsin Energy Board of Directors and Wisconsin Energy's Reasons for the Merger" and "—Opinions of Financial Advisors—Opinion of Wisconsin Energy's Financial Advisor," the Wisconsin Energy Board unanimously (i) determined that it is in the best interest of Wisconsin Energy and its stockholders, and declared it advisable, to enter into the merger agreement, (ii) approved the merger agreement and the transactions contemplated thereby, including the merger, (iii) approved and declared the advisability of the Share Issuance, directed that the Share Issuance proposal be submitted to a vote at a meeting of Wisconsin Energy stockholders and recommended that Wisconsin Energy stockholders vote "FOR" the Share Issuance proposal, and (iv) approved and declared the advisability of the Name Change, directed that the Name Change proposal be submitted to a vote at a meeting of Wisconsin Energy stockholders and recommended that Wisconsin Energy stockholders vote "FOR" the Name Change proposal.

        Following approval by both the boards of directors of both companies, Wisconsin Energy and Integrys executed the merger agreement on June 22, 2014.

Certain Unaudited Prospective Financial Information Utilized by Wisconsin Energy and Integrys

        Wisconsin Energy and Integrys are including in this joint proxy statement/prospectus certain financial forecasts that Wisconsin Energy and Integrys prepared for their respective boards of directors in connection with the proposed merger. These financial forecasts also were provided to Wisconsin Energy's and Integrys' respective financial advisors and utilized in the financial analyses performed in connection with rendering their respective opinions. See "The Merger—Opinions of Financial Advisors" beginning on page 64. Wisconsin Energy and Integrys do not as a matter of course make public projections as to prospective financial information. These financial forecasts were not prepared with a view toward public disclosure or compliance with the guidelines established by the SEC or the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information, but, in the view of Wisconsin Energy's and Integrys' respective managements, were prepared on a reasonable basis. The inclusion of this information in this joint proxy statement/prospectus should not be regarded or considered as an indication by Wisconsin Energy, Integrys or any other recipient of this information, that such information is necessarily predictive of future results. The inclusion of the financial forecasts in this joint proxy statement/prospectus shall not be deemed an admission or representation by Wisconsin Energy or Integrys that such information is material.

        The financial forecasts of Wisconsin Energy and Integrys included in this joint proxy statement/prospectus were prepared by, and are the responsibility of, Wisconsin Energy's management and Integrys' management, respectively, and are unaudited. Neither Wisconsin Energy's nor Integrys' independent auditors, nor any other independent registered public accounting firm, have compiled, examined or performed any procedures with respect to the prospective financial information contained in the financial forecasts, nor have they expressed any opinion or given any form of assurance on the

61


Table of Contents

financial forecasts or their achievability and assume no responsibility for, and disclaim any association with, the prospective financial information. Furthermore, the financial forecasts:

        These financial forecasts were prepared by the respective managements of Wisconsin Energy and Integrys based on information they had at the time of preparation and are not a guarantee of future performance. These financial forecasts were prepared solely for use by Wisconsin Energy's and Integrys' respective boards of directors and financial advisors and are subjective in many respects and thus subject to interpretation. In connection with their respective consideration of the financial forecasts, each of the Wisconsin Energy Board and the Integrys Board, in accordance with its customary practice, believed that it was reasonable to rely on the financial forecasts prepared by each company's management but did not make any formal determination that such financial forecasts were accurate or complete. Neither Wisconsin Energy nor Integrys can assure you that their respective financial forecasts will be realized or that their respective future financial results will not materially vary from the financial forecasts. The financial forecasts cover multiple years and such information by its nature becomes less predictive with each succeeding year.

        The financial forecasts were prepared on reasonable assumptions at the time and do not take into account any circumstances or events occurring after the date they were prepared. Wisconsin Energy and Integrys do not intend to update or revise the financial forecasts. The financial forecasts are forward-looking statements. For more information on factors which may cause Wisconsin Energy's and Integrys' future financial results to materially vary from those projected in the financial forecasts, see "Cautionary Note Regarding Forward-Looking Statements" beginning on page 31 and "Risk Factors" beginning on page 32, as well as Wisconsin Energy's and Integrys' Annual Reports on Form 10-K for the year ended December 31, 2013, Quarterly Reports on Form 10-Q for the period ended June 30, 2014 and respective future SEC filings for a description of risk factors with their respective businesses, results of operations and financial condition.

        In the course of their mutual due diligence, Wisconsin Energy provided Integrys with non-public financial forecasts for the years ending December 31, 2014, 2015, 2016, 2017 and 2018, which forecasts are collectively referred to as the Wisconsin Energy Management Case. In addition, Barclays used in its analysis, and relied primarily on, non-public financial forecasts for the years ending December 31, 2014, 2015, 2016, 2017 and 2018, which forecasts are collectively referred to as the Wisconsin Energy Adjusted Management Case. The Wisconsin Energy Adjusted Management Case was also made available to the Wisconsin Energy Board in connection with the presentation of Barclays' financial

analyses. The Wisconsin Energy Management Case and the Wisconsin Energy Adjusted Management Case are collectively referred to as the Wisconsin Energy forecast.

        The key factor in Wisconsin Energy's performance is the ability to execute on and achieve its strategic plan. The Wisconsin Energy forecast makes certain assumptions, including the full recovery of costs incurred by our regulated utilities and the assumed return on equity rates authorized by the utility commissions that regulate Wisconsin Energy regulated utility business segments for periods after the applicable current rate settlements expire in the various regulated markets Wisconsin Energy serves, as well as future capital expenditures being incorporated into customer rates.

Opinions of Financial Advisors

        Wisconsin Energy engaged Barclays to act as its exclusive financial advisor with respect to the acquisition of Integrys. On June 22, 2014, Barclays rendered its oral opinion (which was subsequently confirmed in writing on the same date) to the Wisconsin Energy Board that, as of such date and based upon and subject to the qualifications, limitations and assumptions stated in its opinion, the merger consideration, to be paid by Wisconsin Energy in the merger is fair, from a financial point of view, to Wisconsin Energy.

its entirety. The following is a summary of Barclays' opinion and the methodology that Barclays used to render its opinion. This summary is qualified in its entirety by reference to the full text of the opinion.

        Barclays' opinion, the issuance of which was approved by Barclays' Valuation and Fairness Opinion Committee, is addressed to the Board of Wisconsin Energy, addresses only the fairness, from a financial point of view, to Wisconsin Energy of the merger consideration to be paid by Wisconsin Energy and does not constitute a recommendation to any stockholder of Wisconsin Energy as to how such stockholder should vote with respect to the proposed transaction or any other matter. The terms of the proposed transaction were determined through arm's-length negotiations between Wisconsin Energy and Integrys and were unanimously approved by the Wisconsin Energy Board. Barclays was not requested to address, and its opinion does not in any manner address, Wisconsin Energy's underlying business decision to proceed with or effect the proposed transaction. In addition, Barclays expressed no opinion on, and its opinion does not in any manner address, the fairness of the amount or the nature of any compensation to any officers, directors or employees of any parties to the proposed transaction, or any class of such persons, relative to the consideration paid in the proposed transaction or otherwise. No limitations were imposed by the Wisconsin Energy Board upon Barclays with respect to the investigations made or procedures followed by it in rendering its opinion.

        In arriving at its opinion, Barclays, among other things reviewed and analyzed:

Table of Contents

        In addition, Barclays had discussions with the management of Wisconsin Energy and Integrys concerning each of Wisconsin Energy's and Integrys' business, operations, assets, liabilities, financial condition and prospects; and undertook such other studies, analyses and investigations as Barclays deemed appropriate.

        In arriving at its opinion, Barclays assumed and relied upon the accuracy and completeness of the financial and other information used by Barclays without any independent verification of such information. Barclays further relied upon the assurances of management of Wisconsin Energy that they were not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the financial projections of Wisconsin Energy and Integrys, upon the advice of Wisconsin Energy, Barclays assumed that such projections were reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of Wisconsin Energy as to the future financial performance of Wisconsin Energy and Integrys and that Wisconsin Energy and Integrys would perform substantially in accordance with such projections. In arriving at its opinion, Barclays assumed no responsibility for and expressed no view as to any such projections or estimates or the assumptions on which they were based. In arriving at its opinion, Barclays did not conduct a physical inspection of the properties and facilities of Wisconsin Energy or Integrys and did not make or obtain any evaluations or appraisals of the assets or liabilities of Wisconsin Energy or Integrys. Barclays' opinion was necessarily based upon market, economic and other conditions as they existed on, and could be evaluated as of, June 22, 2014. Barclays assumed no responsibility for updating or revising its opinion based on events or circumstances that may have occurred after June 22, 2014. Barclays expressed no opinion as to the price at which shares of common stock of Wisconsin Energy would trade following the announcement of the proposed transaction. Barclays' opinion should not be viewed as providing any assurance that the market value of the shares of common stock of Wisconsin Energy to be held by the stockholders of Wisconsin Energy after the consummation of the proposed transaction will be in excess of the market value of common stock of Wisconsin Energy owned by such stockholders at any time prior to the announcement or consummation of the proposed transaction.

        Barclays assumed that the executed merger agreement would conform in all material respects to the last draft reviewed by Barclays. In addition, Barclays assumed the accuracy of the representations and warranties contained in the merger agreement and all agreements related thereto. Barclays also assumed, upon the advice of Wisconsin Energy, that all material governmental, regulatory and third party approvals, consents and releases for the proposed transaction would be obtained within the constraints contemplated by the merger agreement and that the proposed transaction would be consummated in accordance with the terms of the merger agreement without waiver, modification or amendment of any material term, condition or agreement thereof, and that the financing for the proposed transaction would be obtained in accordance with the terms described by Wisconsin Energy. Additionally, Barclays assumed, upon the advice of Wisconsin Energy, that the proposed transaction would qualify as a "reorganization" for United States federal income tax purposes. Barclays did not express any opinion as to any tax or other consequences that might result from the proposed transaction, nor did Barclays' opinion address any legal, tax, regulatory or accounting matters, as to which Barclays understood that Wisconsin Energy had obtained such advice as it deemed necessary from qualified professionals.

        In connection with rendering its opinion, Barclays performed certain financial, comparative and other analyses as summarized below. In arriving at its opinion, Barclays did not ascribe a specific range of values to the shares of Wisconsin Energy common stock but rather made its determination as to fairness, from a financial point of view, to Wisconsin Energy's stockholders of the consideration to be offered by Wisconsin Energy in the proposed transaction on the basis of various financial and comparative analyses. The preparation of a fairness opinion is a complex process and involves various determinations as to the most appropriate and relevant methods of financial and comparative analyses and the application of those methods to the particular circumstances. Therefore, a fairness opinion is not readily susceptible to summary description.

Table of Contents

        In arriving at its opinion, Barclays did not attribute any particular weight to any single analysis or factor considered by it but rather made qualitative judgments as to the significance and relevance of each analysis and factor relative to all other analyses and factors performed and considered by it and in the context of the circumstances of the particular transaction. Accordingly, Barclays believes that its analyses must be considered as a whole, as considering any portion of such analyses and factors, without considering all analyses and factors as a whole, could create a misleading or incomplete view of the process underlying its opinion.

        The following is a summary of the material financial analyses used by Barclays in preparing its opinion to the Wisconsin Energy Board. Certain financial analyses summarized below include information presented in tabular format. In order to fully understand the financial analyses used by Barclays, the tables must be read together with the text of each summary, as the tables alone do not constitute a complete description of the financial analyses. In performing its analyses, Barclays made numerous assumptions with respect to industry performance, general business and economic conditions and other matters, many of which are beyond the control of Wisconsin Energy or any other parties to the proposed transaction. None of Wisconsin Energy, Integrys, merger sub, subsequent merger sub, Barclays or any other person assumes responsibility if future results are materially different from those discussed. Any estimates contained in these analyses are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than as set forth below. In addition, analyses relating to the value of the businesses do not purport to be appraisals or reflect the prices at which the businesses may actually be sold.

Historical Share Price Analysis

        To provide background information and perspective with respect to the historical trading prices of Wisconsin Energy common stock and Integrys common stock, Barclays considered historical data with regard to the trading prices of Wisconsin Energy common stock and Integrys common stock for the period from June 20, 2012 through June 20, 2014.

        Barclays noted that during the period from June 20, 2012 through June 20, 2014, the closing price of Wisconsin Energy common stock increased 21.4 percent, compared to Integrys which increased 7.1 percent.

Selected Comparable Companies

        In order to assess how the public market values shares of similar publicly traded companies, Barclays reviewed and compared specific financial and operating data relating to Wisconsin Energy and Integrys with selected companies that Barclays, based on its experience in the public utilities industry, deemed comparable to Wisconsin Energy and Integrys. The selected comparable companies were:

        Barclays selected the comparable companies listed above because their businesses and operating profiles are reasonably similar to that of Wisconsin Energy and Integrys. However, because no selected comparable company is exactly the same as Wisconsin Energy and Integrys, Barclays believed that it was inappropriate to, and therefore did not, rely solely on the quantitative results of the selected comparable company analysis. Accordingly, Barclays also made qualitative judgments concerning

67


Table of Contents

differences between the business, financial and operating characteristics and prospects of Wisconsin Energy and Integrys and the selected comparable companies that could affect the public trading values of each in order to provide a context in which to consider the results of the quantitative analysis. These qualitative judgments related primarily to the differing sizes, growth prospects, profitability levels and degree of operational risk between Wisconsin Energy and Integrys and the companies included in the selected company analysis.

Selected Comparable Company P/E Trading Analysis

        As part of its selected comparable company analysis, Barclays calculated and analyzed for each of Wisconsin Energy and Integrys the ratio of its current stock price to its historical and projected earnings per share (commonly referred to as a price earnings ratio, or P/E ratio). Based upon the judgments described in the "Selected Comparable Companies" section above, to calculate a range of implied prices per share of Wisconsin Energy and Integrys, Barclays selected (i) an average of 15.9x 2014 estimated P/E ratios applied to management projections for Wisconsin Energy and Integrys and 15.0x 2015 estimated P/E ratios applied to such management projections for the low end of the range and (ii) the average of 17.9x 2014 estimated P/E ratios applied to such management projections and 17.0x 2015 estimated P/E ratios applied to such management projections for the high end of the range. The following summarizes the result of these calculations:

 
  Implied Equity
Value Per Share
 
 
  Low   High  

Wisconsin Energy

  $ 40.46   $ 45.69  

Integrys

  $ 55.88   $ 63.10  

        Using these implied prices per share, Barclays calculated a range of implied exchange ratios from 1.223x to 1.560x. Barclays noted that on the basis of the selected comparable company P/E Trading analysis, the implied acquisition exchange ratio of 1.524x (assuming 100 percent stock consideration) was within this range of implied exchange ratios.

Selected Comparable Company EV/EBITDA Analysis

        In addition to calculating implied prices per share based on estimated P/E ratios, Barclays calculated and analyzed for each of Wisconsin Energy and Integrys the ratio of its enterprise value (calculated by adding its short-term and long-term debt to the sum of the market value of its common equity and the book value of any preferred and minority interest, and subtracting its unrestricted cash and cash equivalents) to its projected earnings before interest, taxes and depreciation and amortization (commonly referred to as an EV/EBITDA ratio). Proportional amounts of EBITDA and debt relating to American Transmission Company were included in the calculations of EBITDA and debt to EV. Based upon the judgments described in the "Selected Comparable Companies" section above, to calculate a range of implied prices per share of Wisconsin Energy and Integrys, Barclays selected (i) the average of 8.6x of the 2014 estimated EV/EBITDA ratios applied to management projections for Wisconsin Energy and Integrys and 8.2x of the 2015 estimated EV/EBITDA ratios applied to such management projections for the low end of the range and (ii) the average of 9.6x of the 2014 estimated EV/EBITDA ratios applied to such management projections and the average of 9.2x of the 2015

estimated EV/EBITDA ratios applied to such management projections for the high end of the range. The following summarizes the result of these calculations:

 
  Implied Equity
Value Per Share
 
 
  Low   High  

Wisconsin Energy

  $ 36.31   $ 43.56  

Integrys

  $ 56.87   $ 69.60  

        Using these implied prices per share, Barclays calculated a range of implied exchange ratios from 1.306x to 1.917x. Barclays noted that on the basis of the selected comparable company EV/EBITDA analysis, the implied acquisition exchange ratio of 1.524x (assuming 100 percent stock consideration) was within this range of implied exchange ratios.

Selected Precedent Transaction Analysis

        Barclays reviewed and compared the purchase prices and financial multiples paid in selected other transactions that Barclays, based on its experience with merger and acquisition transactions, deemed relevant. Barclays chose such transactions based on, among other things, the similarity of the applicable target companies in the transactions to Integrys with respect to the size, mix, margins and other characteristics of their businesses. The transactions reviewed by Barclays are set forth in the table below. Using publicly available information for each of the selected precedent transactions, Barclays calculated the ratio of the acquisition stock price to the target's one-year forward projected earnings per share (commonly referred to as a price earnings ratio, or P/E ratio) and the ratio of the target's acquisition enterprise value to the target's one-year forward projected earnings before interest, taxes and depreciation and amortization (commonly referred to as an EV/EBITDA ratio). The equity value of the target was calculated as the acquisition stock price multiplied by the shares outstanding at the date of announcement. The enterprise value of the target was calculated as the aforementioned equity value plus the short-term and long-term debt and the book value of any preferred and minority interest, and subtracting unrestricted cash and cash equivalents.

  AES Corp.   DPL Inc.     7.8x     12.4x  

December 2010

  AGL Resources   Nicor Gas Company     7.3x     17.2x  

        The reasons for and the circumstances surrounding each of the selected precedent transactions analyzed were diverse and there are inherent differences in the business, operations, financial conditions and prospects of Wisconsin Energy and the companies included in the selected precedent transaction analysis. Accordingly, Barclays believed that a purely quantitative selected precedent transaction analysis would not be particularly meaningful in the context of considering the proposed transaction. Barclays therefore made qualitative judgments concerning differences between the characteristics of the selected precedent transactions and the proposed transaction which would affect the acquisition values of the selected target companies and Integrys. Based upon these judgments, Barclays selected the highest FY1 P/E multiple in the precedent list and applied it to the management projections for both Wisconsin Energy and Integrys and the highest FY1 EV / EBITDA multiple in the

69


Table of Contents

precedent list and applied it to management projections for both Wisconsin Energy and Integrys. For Wisconsin Energy, the larger of the two implied Wisconsin Energy equity values was used to calculate the high end of the implied equity value per share range, and for Integrys, the larger of the two implied Integrys equity values was used to calculate the high end of the implied equity value per share range. Barclays selected the lowest FY1 P/E multiple in the precedent list and applied it to the management projections for both Wisconsin Energy and Integrys and the lowest FY1 EV / EBITDA multiple in the precedent list applied to management projections for both Wisconsin Energy and Integrys. For Wisconsin Energy, the lower of the two implied Wisconsin Energy equity values was used to calculate the low end of the implied equity value per share range, and for Integrys, the lower of the two implied Integrys equity values was used to calculate the low end of the implied equity value per share range. The following summarizes the result of these calculations:

 
  Implied Equity
Value Per Share
 
 
  Low   High  

Wisconsin Energy

  $ 28.81   $ 59.36  

Integrys

  $ 38.56   $ 81.32  

        Using these implied prices per share, Barclays calculated a range of implied exchange ratios from 0.650x to 2.822x. Barclays noted that on the basis of the selected comparable company analysis, the implied acquisition exchange ratio of 1.524x (assuming 100 percent stock consideration) was within this range of implied exchange ratios.

Discounted Cash Flow Analysis

        In order to estimate the present value of Wisconsin Energy common stock and the Integrys common stock, Barclays performed a discounted cash flow analysis of each of Wisconsin Energy and Integrys, respectively. A discounted cash flow analysis is a traditional valuation methodology used to derive a valuation of an asset by calculating the "present value" of estimated future cash flows of the asset. "Present value" refers to the current value of future cash flows or amounts and is obtained by discounting those future cash flows or amounts by a discount rate that takes into account macroeconomic assumptions and estimates of risk, the opportunity cost of capital, expected returns and other appropriate factors.

        To calculate the estimated enterprise value of Wisconsin Energy and Integrys using the discounted cash flow method, Barclays added each of Wisconsin Energy's and Integrys' respective (i) the present value of projected after-tax unlevered free cash flows for fiscal years 2015 through 2018 based on management projections to (ii) the present value of the "terminal value" at the end of fiscal year 2018 for each of Wisconsin Energy and Integrys, which present values were discounted using a range of selected discount rates based on a December 31,2014 valuation date. The after-tax unlevered free cash flows were calculated by taking the tax-affected earnings before interest and taxes (using a marginal tax rate of 38 percent and including the proportion attributable to American Transmission Company), adding back the aggregate of depreciation and amortization (including the proportion attributable to American Transmission Company), subtracting capital expenditures (including the proportion attributable to American Transmission Company) and adjusting for changes in working capital, deferred taxes and any other changes in cash flows from operations and investments. The residual value of Wisconsin Energy and Integrys, respectively, at the end of the forecast period, or "terminal value," was estimated by averaging a range of terminal value multiples based on forward EBITDA of 8.6x to 9.6x, and forward earnings of 15.9x to 17.9x which was derived by analyzing the results from the selected comparable company analysis and applying such range to the management projections. The range of after-tax discount rates of 4.78 percent to 5.78 percent for Wisconsin Energy and 5.82 percent to 6.82 percent for Integrys were selected based on an analysis of the weighted average cost of capital of Wisconsin Energy and Integrys, respectively. Barclays then calculated a range of implied prices per

Table of Contents

share of the common stock of each of Wisconsin Energy and Integrys by subtracting estimated net debt, preferred and minority interest as of the end of 2014 (including proportional amounts for American Transmission Company) from the estimated enterprise value of each of Wisconsin Energy and Integrys, respectively, using the discounted cash flow method and dividing such amount by the fully diluted number of shares of common stock of each of Wisconsin Energy and Integrys, respectively. The following summarizes the result of these calculations:

 
  Discounted Cash
Flow Value Range
 
 
  Low   High  

Wisconsin Energy

  $ 42.55   $ 51.34  

Integrys

  $ 63.46   $ 78.35  

        Using these implied prices per share, Barclays calculated a range of implied exchange ratios from 1.236x to 1.841x. Barclays noted that on the basis of the discounted cash flow analysis, the implied acquisition exchange ratio of 1.524x (assuming 100 percent stock consideration) was within this range of implied exchange ratios

Contribution Analysis

        Barclays performed a relative contribution analysis of Wisconsin Energy and Integrys in which Barclays reviewed selected estimated future financial information for Wisconsin Energy and Integrys to determine Wisconsin Energy's and Integrys' relative contribution to the combined company after the merger. Barclays analyzed Wisconsin Energy's and Integrys' relative contribution to estimated leverage adjusted EBITDA, net income and cash flow from operations of the combined company for the calendar years of 2015 through 2018. Leverage adjusted EBITDA for each year reviewed was calculated by applying the EBITDA contribution percentage of one company to the sum of each company's total enterprise value and then subtracting out that company's projected net debt amount for that year. Financial data of Wisconsin Energy and Integrys were based on the forecasts provided to Barclays management by Wisconsin Energy.

        Based on the relative contributions of Wisconsin Energy and Integrys to the combined company calculated in the contribution analysis, Barclays determined a range of implied exchange ratios for Wisconsin Energy common shares to Integrys common shares. The following table reflects the results of the analysis, as compared to the implied acquisition exchange ratio of 1.524x (assuming 100 percent stock consideration):

Pro Forma Accretion/Dilution Analysis

        Barclays analyzed and considered the impact of the merger on the estimated earnings per share and dividends per share of Wisconsin Energy for each of the years 2015 through 2018, using projections provided by management of Wisconsin Energy. Barclays assumed that, among other things: (i) the closing of the transaction would occur on December 31, 2014, (ii) $1.7 billion of Wisconsin Energy debt would be issued upon the closing of the transaction, (iii) Wisconsin Energy's current share repurchase plan would be eliminated and (iv) an increase in Wisconsin Energy's dividend level would occur following the closing of the transaction, to a level consistent with Integrys' then-indicated dividend as adjusted for the exchange ratio and portion of the value received by Integrys' stockholders in the form of cash consideration.

        Based on this analysis, the merger is expected to result in an increase in earnings per share and dividends per share when compared to Wisconsin Energy's estimated earnings per share and dividends per share in the projections provided by management of Wisconsin Energy on a stand-alone basis in the years 2015 through 2018.

Historical Exchange Ratio Analysis

        To provide background information and perspective with respect to the historical share prices of Wisconsin Energy common stock and Integrys common stock, Barclays reviewed the daily historical closing share prices of Wisconsin Energy common stock and Integrys common stock for the period from June 20, 2012 to June 20, 2014. Barclays analyzed the ratio of the daily closing common share price for Wisconsin Energy to the corresponding common share price of Integrys over the two year period. In addition, Barclays reviewed the implied relative exchange ratio of the closing common share price for Wisconsin Energy and closing common share price of Integrys based on the spot, 5-trading-day, 10-trading-day, 20-trading-day, 30-trading-day, 60-trading-day and one-year and two-year volume weighted average prices, respectively, as of June 20, 2014. The following table exhibits the results of this analysis, reflecting implied relative exchange ratios ranging from 1.273x to 1.360x Wisconsin Energy common shares per Integrys common share, as compared to the implied acquisition exchange ratio of 1.524x (assuming 100 percent stock consideration).

Lazard did not conduct any independent valuation or appraisal of any of the assets or liabilities (contingent or otherwise) of Integrys or Wisconsin Energy or concerning the solvency or fair value of Integrys or Wisconsin Energy, and Lazard was not furnished with any such valuation or appraisal. Management of Integrys advised Lazard that management's base case financial forecasts, which are referred to in this section as the "Base case," represent the best currently available estimates and judgments as to the future financial performance of Integrys and, accordingly, for purposes of Lazard's analyses in connection with its opinion, Integrys directed Lazard to utilize the "Base case" set forth in Integrys' financial forecasts. With respect to the financial forecasts utilized in Lazard's analyses, including those related to the illustrative synergies and other benefits anticipated by management of Integrys to be realized from the merger, as well as Wisconsin Energy's financial forecasts, which are referred to in this section as the Wisconsin Energy management plan, Lazard assumed, at the direction of Integrys, that they were reasonably prepared on bases reflecting the best currently available estimates and judgments as to the future financial performance of Integrys and Wisconsin Energy, respectively, and such synergies and other benefits. Lazard assumed no responsibility for and expressed no view as to any such forecasts or the assumptions on which they were based.

        In rendering its opinion, Lazard assumed, with the consent of Integrys, that the merger would be consummated on the terms described in the merger agreement, without any waiver or modification of any terms or conditions material to Lazard's analysis. Representatives of Integrys advised Lazard, and Lazard assumed, that the merger agreement, when executed, would conform to the draft reviewed by Lazard, dated June 20, 2014, in all material respects. Lazard also assumed, with the consent of Integrys, that obtaining the necessary governmental, regulatory or third-party approvals and consents for the merger would not have an adverse effect on Integrys, Wisconsin Energy or the merger. Lazard further assumed, with the consent of Integrys, that the merger qualifies for U.S. federal income tax purposes as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended. Lazard did not express any opinion as to any tax or other consequences that might result from the merger, nor did Lazard's opinion address any legal, tax, regulatory or accounting matters, as to which Lazard understood that Integrys had obtained such advice as it deemed necessary from

qualified professionals. Lazard expressed no view or opinion as to any terms or other aspects (other than the per share merger consideration to the extent expressly specified in the opinion) of the merger, including, without limitation, the form or structure of the merger or any agreements or arrangements entered into in connection with, or contemplated by, the merger. In addition, Lazard expressed no view or opinion as to the fairness of the amount or nature of, or any other aspects relating to, the compensation to any officers, directors or employees of any parties to the merger, or class of such persons, relative to the per share merger consideration or otherwise.

        In connection with rendering its opinion, Lazard performed certain financial analyses and reviews of certain information that Lazard deemed appropriate in connection with rendering its opinion as summarized below under "—Summary of Lazard Financial Analyses" and "—Other Analyses." The summary of the analyses and reviews provided below under "—Summary of Lazard Financial Analyses" and "—Other Analyses" is not a complete description of the analyses and reviews underlying Lazard's opinion. The preparation of a fairness opinion is a complex process involving various determinations as to the most appropriate and relevant methods of financial analysis and review and the application of those methods to particular circumstances, and, therefore, is not readily susceptible to partial analysis or summary description. Considering selected portions of these analyses and reviews or the summary contained in "—Summary of Lazard Financial Analyses" and "—Other Analyses," without considering the analyses and reviews as a whole, could create an incomplete or misleading view of the analyses and reviews underlying Lazard's opinion. In arriving at its opinion, Lazard considered the results of all of its analyses and reviews and did not attribute any particular weight to any particular analysis or review or application thereof considered by it; rather, Lazard made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of its analyses and reviews.

        For purposes of its analyses and reviews, Lazard considered industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of Integrys. No company, business or transaction used in Lazard's analyses and reviews, as a comparison, is identical to Integrys, its business or the merger, and an evaluation of the results of those analyses and reviews is not entirely mathematical. Rather, the analyses and reviews involve complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the acquisition, public trading or other values of the companies, businesses or transactions used in Lazard's analyses and reviews. The estimates contained in Lazard's analyses and reviews and the ranges of valuations resulting from any particular analysis or review are not necessarily indicative of actual results or values or predictive of future results or values, which may be significantly more or less favorable than those suggested by Lazard's analyses and reviews. In addition, analyses and reviews relating to the value of companies, businesses or securities do not purport to be appraisals or to reflect the prices at which companies, businesses or securities actually may be sold. Accordingly, the estimates used in, and the results derived from, Lazard's analyses and reviews are inherently subject to substantial uncertainty.

The tables alone do not constitute a complete description of Lazard's analyses and reviews. Considering the data in the tables below without considering the full description of the analyses and reviews, including the methodologies and assumptions underlying the analyses and reviews, could create a misleading or incomplete view of Lazard's analyses and reviews.

Selected Comparable Company Multiples Analysis

        Lazard reviewed and analyzed certain financial information, valuation multiples and market trading data related to selected comparable publicly traded regulated utility companies whose operations Lazard believed, based on its experience with companies in the regulated utility industry and its professional judgment, to be generally relevant in analyzing each of Integrys' and Wisconsin Energy's operations for the purposes of this analysis. Lazard compared such information of the selected comparable companies to the corresponding information for Integrys and Wisconsin Energy.

        The selected group of companies used in this analysis with respect to Integrys, which we refer to in this registration statement as the Integrys comparable companies, was as follows:

        The selected group of companies used in this analysis with respect to Wisconsin Energy, which we refer to in this registration statement as the Wisconsin Energy comparable companies, was as follows:

        Lazard selected the companies reviewed in this analysis because, among other things, the Integrys comparable companies and the Wisconsin Energy comparable companies operate businesses similar to the businesses of Integrys and Wisconsin Energy, respectively. However, no selected company is identical to Integrys or Wisconsin Energy. Accordingly, Lazard believes that purely quantitative analyses are not, in isolation, determinative in the context of the merger and that qualitative judgments concerning differences between the business, financial and operating characteristics and prospects of each of Integrys and Wisconsin Energy and the Integrys comparable companies and Wisconsin Energy comparable companies, respectively, that could affect the public trading values of each company are also relevant. For purposes of reviewing Wisconsin Energy as an Integrys comparable company and Integrys as a Wisconsin Energy comparable company in this analysis, Lazard utilized publicly available information for the companies instead of the internal projections provided in the "Base case" and the Wisconsin Energy management plan, as applicable.

        Lazard calculated and compared various financial multiples and ratios of each of the comparable companies, including, among other things:

Table of Contents

        Lazard applied each such range of multiples for the Integrys comparable companies and the Wisconsin Energy comparable companies to the relevant financial statistics of Integrys and Wisconsin Energy, respectively, as reflected in the "Base case" financial forecasts for Integrys, and the Wisconsin Energy management plan for Wisconsin Energy. Lazard averaged the results of these calculations and, from this analysis, estimated an implied value range for shares of Integrys common stock and an implied value range for shares of Wisconsin Energy common stock.

        This analysis resulted in an implied price per share range for shares of Integrys common stock and shares of Wisconsin Energy common stock, as compared to the per share merger consideration provided in the merger agreement, as set forth below:

Implied Integrys
Price Per Share Range
  Implied Wisconsin Energy
Price Per Share Range
  Merger Consideration
$58.25 - $62.75   $41.75 - $45.25   $18.58 in cash and 1.128 shares of common stock of Wisconsin Energy (equivalent to $71.47 per share based upon Wisconsin Energy's closing share price on June 20, 2014)

Consolidated Discounted Cash Flow Analysis

        Lazard performed a discounted cash flow analysis of each of Integrys and Wisconsin Energy, which is a valuation methodology used to derive a valuation of a company by calculating the present value of its estimated future cash flows. "Future cash flows" refers to projected unlevered free cash flows of a company. "Present value" refers to the current value of future cash flows or amounts and is obtained by discounting those future cash flows or amounts by a discount rate that takes into account macroeconomic assumptions and estimates of risk, the opportunity cost of capital, capital structure, income taxes, expected returns and other appropriate factors. Lazard calculated the discounted cash flow value for each of Integrys and Wisconsin Energy as the sum of the net present value, as of December 31, 2013, which we refer to as the discount date, of each of:

        The estimated future cash flow for each of Integrys and Wisconsin Energy was calculated by Lazard based on the "Base case" as set forth in Integrys' financial forecasts, and the Wisconsin Energy management plan as summarized above in "—Opinion of Lazard Frères & Co. LLC". For its discounted cash flow calculations for both companies, Lazard applied discount rates ranging from 5.25 percent to 5.75 percent. Such discount rates were based on Lazard's estimated range of weighted average cost of capital, derived from a number of factors, including, among others, the median unlevered risk profile of each company's selected group of comparable companies as set forth above in "—Selected Comparable Company Multiples Analysis", each company's weighted cost to maturity of its long-term debt and each company's consolidated leverage ratio.

        The terminal value of the companies was calculated applying terminal year EBITDA multiples ranging from 8.5x to 9.0x to Integrys' projected terminal year EBITDA of $1,220 million and

9.0x to 9.5x to Wisconsin Energy's projected terminal year EBITDA of $1,984 million, and applying terminal year P/E Multiples, ranging from 16.0x to 17.0x to Integrys' projected terminal year earnings of $388 million and 16.5x to 17.5x to Wisconsin Energy's projected terminal year earnings of $717 million. The exit terminal year EBITDA multiples for Integrys and Wisconsin Energy were selected by Lazard by reference to enterprise value to EBITDA trading multiples calculated for Integrys and Wisconsin Energy as well as the enterprise value to EBITDA trading multiples of the Integrys comparable companies and the Wisconsin Energy comparable companies, respectively. The exit terminal year P/E Multiples were selected by Lazard by reference to P/E trading multiples calculated for Integrys and Wisconsin Energy as well as the P/E Multiples of the Integrys comparable companies and the Wisconsin Energy comparable companies, respectively. As part of the total implied equity value calculated for Integrys and Wisconsin Energy, Lazard calculated and deducted from enterprise value the book value of the outstanding financial debt less cash, cash equivalents and marketable securities.

        Lazard averaged the price per share ranges implied by these calculations and, based on that analysis, reviewed the implied price per share range for shares of Integrys common stock and shares of Wisconsin Energy common stock as compared to the per share merger consideration provided in the merger agreement as set forth below:

Implied "Base case"

Per Share Range
$56.00 - $63.75   $64.75 - $74.24

Dividend Discount Analysis

        Lazard performed a dividend discount analysis of shares of Integrys common stock, which calculates an implied equity value per share by discounting to the present the value of the future dividends per share of Integrys common stock expected to be paid by Integrys, as reflected in the "Base case" financial forecasts for Integrys prepared by the management of Integrys, based on an assumed equity discount rate ranging from 6.75 percent to 7.75 percent and an assumed dividend growth rate beyond 2018 ranging from approximately 1.5 percent to 2.5 percent.

        Lazard applied these assumptions and calculated the range of present value of Integrys' 2014 to 2018 dividends as $11.69 to $11.95 per share and the present value of Integrys' post-2018 dividends as $33.43 to $52.02 per share. This analysis resulted in an implied price per share range for shares of Integrys common stock, as compared to the per share merger consideration provided in the merger agreement, as set forth below:

        Lazard also performed a dividend discount analysis of shares of Wisconsin Energy common stock, which calculates an implied equity value per share by discounting to the present the value of the future dividends per share of Wisconsin Energy common stock expected to be paid by Wisconsin Energy, as reflected in the Wisconsin Energy management plan, based on an assumed equity discount rate ranging from 6.75 percent to 7.75 percent and an assumed dividend growth rate beyond 2018 ranging from approximately 1.5 percent to 2.5 percent.

Table of Contents

        Lazard applied these assumptions and calculated the range of present value of Wisconsin Energy's 2014 to 2018 dividends as $7.47 to $7.65 per share and the present value of Wisconsin Energy's post-2018 dividends as $23.05 to $35.86 per share. This analysis resulted in an implied price per share range for shares of Wisconsin Energy common stock as set forth below:

Pro Forma Total Shareholder Return Analysis

        In order to determine the implied total shareholder return resulting from the merger relative to the standalone case in each of 2014, 2015, 2016, 2017 and 2018, which we refer to as the observed years, Lazard compared (i) Integrys' estimated future stock price based on stand-alone EPS (using a forward P/E Multiple of 16.9x) and cumulative dividends for each of the observed years as reflected in the "Base case" with (ii) Integrys' per share value based on (x) estimated EPS (derived from the stand-alone estimates for each of Integrys and Wisconsin Energy reflected in the "Base case" and Wisconsin Energy management plan, respectively, and reflecting an illustrative blended P/E Multiple of 17.8x) and (y) cumulative dividends of the pro forma combined company for each of those years, adjusted to reflect the merger consideration of 1.128 shares of the common stock of Wisconsin Energy and $18.58 in cash per share of Integrys common stock.

        In conducting this analysis, Lazard assumed (i) a transaction closing date of December 31, 2014, (ii) estimated total retained synergies of $101 million achieved in the third year following the transaction, with $32 million of synergies achieved in the first year and $66 million in the second year, (iii) the exclusion of potential purchase accounting adjustments resulting from write-ups or write-downs of certain accounts, (iv) that Integrys will not effect a $300 million share repurchase in 2014, (v) that the pro forma dividend would be set at the greater of Integrys' and Wisconsin Energy's dividends, as determined in accordance with their respective policies, in each year, (vi) no change in equity stock issuances or repurchases from Integrys' and Wisconsin Energy's standalone policies, (vii) that the pro forma combined company trades at Wisconsin Energy's one-year forward P/E Multiple of 17.8x, (viii) a pro forma minimum cash balance equal to Integrys' and Wisconsin Energy's combined estimated year-end cash balance in 2014 of $1 million and (ix) that debt from the transaction would be issued at a 4.0 percent interest rate.

        This analysis indicated that the value accrued by Integrys shareholders through the merger is expected to be accretive relative to the value accrued by such shareholders through the "Base case" for Integrys for each of the observed years.


Miscellaneous

        In connection with Lazard's services as financial advisor to Integrys with respect to the merger, Integrys agreed to pay Lazard a fee equal to approximately $18.5 million (calculated based on the transaction value as of June 24, 2014), of which one-fourth became payable upon the rendering of Lazard's opinion and the remainder is contingent upon the closing of the merger. Integrys has also agreed to reimburse Lazard for certain expenses incurred in connection with Lazard's engagement and to indemnify Lazard and certain related persons under certain circumstances against various liabilities that may arise from or be related to Lazard's engagement. Lazard in the past has provided, currently is providing and in the future may provide certain investment banking services to Integrys, for which Lazard has received and may receive compensation. Lazard and its affiliates have received fees of $450,000 over the past three years for providing such investment banking services to Integrys. Lazard and its affiliates have not received fees for providing financial advisory services to Wisconsin Energy during the last three years.

        Lazard, as part of its investment banking business, is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements, leveraged buyouts, and valuations for estate, corporate and other purposes. In addition, in the ordinary course, Lazard and its respective affiliates and employees may trade securities of Integrys, Wisconsin Energy and certain of their respective affiliates for their own accounts and for the accounts of their customers, may at any time hold a long or short position in such securities, and may also trade and hold securities on behalf of Integrys, Wisconsin Energy and certain of their respective affiliates. The issuance of Lazard's opinion was approved by the opinion committee of Lazard.

        Lazard is an internationally recognized investment banking firm providing a full range of financial advisory and other services. Lazard was selected to act as investment banker to Integrys because of its qualifications, expertise and reputation in investment banking and mergers and acquisitions generally and in the utility industry specifically, as well as its familiarity with the business of Integrys.

        Integrys and Wisconsin Energy determined the merger consideration of $18.58 in cash and 1.128 shares of the common stock, par value $0.01 per share, of Wisconsin Energy per share of Integrys common stock to be paid to the holders of Integrys common stock (other than the excluded holders) in the merger through arm's-length negotiations, and the Integrys Board unanimously approved such per share merger consideration. Lazard did not recommend any specific consideration to the Integrys Board or any other person or indicate that any given consideration constituted the only appropriate consideration for the merger. Lazard's opinion was one of many factors considered by the Integrys Board, as discussed further in "The Merger—Recommendations of the Integrys Board of Directors and Integrys' Reasons for the Merger" beginning on page 57.


Governance of Wisconsin Energy Following Completion of the Merger

        Upon completion of the merger, Wisconsin Energy has agreed to take all necessary action (i) to cause its corporate headquarters and principal executive offices to be located in metropolitan Milwaukee, Wisconsin, and (ii) to have operational headquarters in Milwaukee, Wisconsin, Chicago, Illinois and Green Bay, Wisconsin.

        Upon completion of the merger, Wisconsin Energy has agreed to maintain historic levels of community involvement and charitable contributions in Integrys' and its subsidiaries' existing service territories following the merger.


Interests of Directors and Executive Officers in the Merger

Interests of Directors and Executive Officers of Wisconsin Energy in the Merger

        In considering the recommendations of the Wisconsin Energy Board with respect to its approval of the merger agreement, Wisconsin Energy stockholders should be aware that Wisconsin Energy's directors and executive officers have interests in the merger that are different from, or in addition to, those of the Wisconsin Energy stockholders generally. The Wisconsin Energy Board was aware of these interests and considered them, among other matters, in approving the merger agreement and making its recommendation that the Wisconsin Energy stockholders vote "FOR" the proposals set forth in this joint proxy statement/prospectus. See "The Merger—Recommendations of the Wisconsin Energy Board of Directors and Wisconsin Energy's Reasons for the Merger" beginning on page 52. These interests are as follows:

Interests of Directors and Executive Officers of Integrys in the Merger

        Integrys executive officers and directors have interests in the merger that are different from, or in addition to, those of Integrys' shareholders generally. In considering the recommendations of the Integrys Board, including that you vote to approve the Merger proposal, you should be aware of these interests.

Table of Contents

        Integrys executive officers and directors who own Integrys common stock will receive the same merger consideration on the same terms and conditions as other Integrys shareholders. The following table sets forth the number of shares of Integrys common stock (rounded to the nearest whole share) beneficially owned by each of our executive officers and directors as of June 30, 2014, the latest practicable date to determine such amounts before the filing of this joint proxy statement/prospectus, and the aggregate merger consideration that would be payable for such shares of Integrys common stock. The amounts shown in this table also include Integrys Time-Based RSUs and Integrys Performance-Based RSUs that are expected to vest pursuant to their terms between June 30, 2014 and June 22, 2015 (the end date, as described above in "Termination of the Merger Agreement; Termination Fees" beginning on page 22), assuming the achievement of performance conditions at target level and without regard to any additional deferrals or tax withholding with respect thereto but do not include other unvested Integrys Equity-Based Awards (as defined below). For purposes of this table, the merger consideration is assumed to equal $69.62, the average closing market price of Integrys common stock on the NYSE over the first five business days following the first public announcement of the transaction on June 23, 2014. As discussed in the section entitled "The Merger Agreement—Effect of the Merger on Capital Stock—Conversion of Common Stock of Integrys" beginning on page 114, the value of the merger consideration on the closing date will depend on the per share price of Wisconsin Energy common stock on the closing date and therefore the actual aggregate merger consideration received may be different from the amount shown below.

        For a description of the treatment of Integrys stock options, Integrys Time-Based RSUs, Integrys Performance-Based RSUs and Integrys Deferred Stock Units (which we refer to collectively as the Integrys Equity-Based Awards) held by Integrys executive officers and directors, please see below under "—Treatment of Stock Options, RSUs and Deferred Stock Units."

Table of Contents

        Upon completion of the merger, outstanding Integrys equity awards, including Integrys stock options, Integrys Time-Based RSUs, Integrys Performance-Based RSUs and Integrys Deferred Stock Units, in each case, whether vested or unvested, will be cancelled. In connection with the merger:

        The table below sets forth, for each Integrys executive officer and director, (i) the number of Integrys stock options (both vested and unvested), (ii) the number of Integrys Time-Based RSUs and Integrys Performance-Based RSUs (assuming the achievement of performance conditions at target level) and (iii) the number of Integrys Deferred Stock Units, each held by such executive officers and directors as of June 30, 2014, the latest practicable date to determine such amounts before the filing of this joint proxy statement/prospectus. The table below also sets forth the total amount, per individual, payable in respect of such Equity-Based Awards on the closing date, with such amounts calculated by multiplying the number of Integrys stock options by the excess, if any, of the equity award consideration over the exercise price per share of Integrys common stock, and by multiplying the number of Integrys Time-Based RSUs, Integrys Performance-Based RSUs and Integrys Deferred Stock Units by the equity award consideration. For purposes of this table, the equity award consideration is

92


Table of Contents

assumed to equal $69.62, the average closing market price of Integrys common stock on the NYSE over the first five business days following the first public announcement of the transaction on June 23, 2014.

        The equity award consideration depends on the per share price of Wisconsin common stock prior to the closing date (which is not determinable at this time) and therefore the actual equity award consideration may be different from the estimated equity award consideration. The amounts shown do not include any Integrys Time-Based RSUs and Integrys Performance-Based RSUs that are expected to vest pursuant to their terms between June 30, 2014 and June 22, 2015 (the end date, as described above in "Termination of the Merger Agreement; Termination Fees" beginning on page 22). Instead, such awards are included in the table above in "—Consideration Payable for Shares in the Merger" beginning on page 91. The amounts shown do not attempt to forecast any grants, dividends, additional deferrals or forfeitures of Equity-Based Awards following the date of this joint proxy statement/prospectus. Depending on when the closing date occurs, certain Equity-Based Awards shown in the table may vest in accordance with their terms. Pursuant to the terms of the original award agreements, any executive officer who has attained age 62, or age 55 and completed 10 years of service, would remain entitled to retain his or her Equity-Based Awards, whether or not vested, in the event of such executive officer's termination of employment, regardless of whether the merger transaction occurs.

        Pursuant to the DCP, certain key employees and nonemployee directors may defer payment of a portion of their compensation or fees to a deferral account on a pre-tax basis. Compensation is generally deferred in the form of cash and is indexed to certain investment options or units of Integrys common stock.

Table of Contents

        In connection with the execution of the merger agreement, Integrys has and will continue to make periodic contributions to the rabbi trust associated with the DCP, pursuant to its terms, in an amount sufficient to satisfy the actuarial present value of obligations under the DCP.

        Pursuant to the SERP, certain Integrys executive officers are entitled to receive nonqualified supplemental retirement benefits that provide income replacement which, when taking into account other retirement benefits provided to the executive, ensures that the executive will receive a retirement benefit of 60 percent of his or her final average pay (calculated to include both base salary and short-term incentive compensation payments over the last 36 months or the 3 preceding years, whichever is higher). To qualify for the full supplemental retirement benefit, the executive must have completed 15 years of service and retired or terminated employment after age 62. Reduced benefits are payable if the executive has attained age 55 and completed 10 years of service at retirement or termination of employment.

        Under the terms of the SERP, in the event an executive is terminated by Integrys without "cause" (as defined in the SERP) or resigns for "good reason" (as defined below under "—Individual Employment Arrangements and Executive Change in Control Severance Plan") following completion of the merger and prior to the second anniversary thereof, if the executive is eligible to participate in the SERP but is not yet eligible for a supplemental retirement benefit thereunder, such executive will nevertheless be entitled to a supplemental retirement benefit if such executive has a vested benefit under the Integrys pension plan and has completed five or more years of credited service as of the date of such executive's termination.

        Mr. Borgard, Mr. Radtke and Mr. Verbanac participate in the SERP and have not yet attained age 55.

        Each of Integrys' executive officers is either party to an Employment and Severance Agreement with Integrys, which we refer to collectively as the Executive Agreements, or a participant in Integrys' Executive Change in Control Severance Plan, which we refer to as the Change in Control Plan. Both the Executive Agreements and the Change in Control Plan provide enhanced benefits in the event an executive officer experiences a qualifying termination in conjunction with the completion of a transaction such as the merger. Mr. Mikulsky's Executive Agreement expired pursuant to its terms upon his attainment of normal retirement age, and was renewed in connection with the merger.

        The Executive Agreements and the Change in Control Plan generally provide that, in the event the executive is terminated by Integrys without "cause" (as defined below) or resigns for "good reason" (as defined below) following completion of the merger and prior to the second anniversary thereof, subject to the executive officer's execution and non-revocation of a release of claims in favor of Integrys he or she will be paid a lump sum cash amount (less any required withholding taxes) equal to the sum of (i) the executive officer's applicable severance multiple times the sum of such executive's annual base salary during the 180-day period prior to completion of the merger and the greater of such executive officer's target annual incentive award for the year of termination or the year in which the merger occurred, payable in a lump sum on the last business day of the seventh month following the month in which the executive's termination of employment occurs, and (ii) an amount equal to the greater of the actual incentive award the executive officer would be entitled to for the year of termination or the prorated target annual incentive award, payable at the same time as annual incentive awards are normally paid. The severance multiple for Messrs. Schrock, Radtke, Borgard and Verbanac is 2.99; the severance multiple for Messrs. Laakso, Schott, Cloniger, Mikulsky and Morrow and Ms. Caro is 2.0 and the severance multiple for Mr. Guc and Ms. Kallas is 1.0.

        In addition, each executive would also be entitled to reimbursement for limited outplacement assistance, continued welfare benefits (ranging from one to two years following the completion of the

94


Table of Contents

merger or the date on which the executive has attained age 65 (other than Mr. Mikulsky) or obtained comparable coverage under a new employer, if earlier) and limited reimbursement for fees and expenses of consultants and/or legal or accounting advisors engaged by the executive to advise as to matters related to the Executive Agreements or the Change in Control Plan, as applicable.

        Under the Executive Agreements and the Change in Control Plan, in the event the executive's employment is terminated without cause and the completion of the merger occurs within 180 days after the executive's termination, then, for all purposes, such termination will be deemed a qualifying termination and will entitle the executive to the severance and benefits described above unless Integrys determines that such termination (i) was not at the request of Wisconsin Energy or (ii) would not have otherwise arisen in connection with or in anticipation of the completion of the merger.

        For purposes of the Executive Agreements and the Change in Control Plan, "cause" is generally defined as the occurrence of any of the following events: (i) the executive engaging in intentional conduct not taken in good faith that has caused demonstrable and serious financial injury to Integrys and/or a subsidiary, as evidenced by a determination in a binding and final judgment, order or decree of a court or administrative agency of competent jurisdiction, in effect after exhaustion or lapse of all rights of appeal, in an action, suit or proceeding, whether civil, criminal, administrative or investigative; (ii) conviction of a felony (as evidenced by binding and final judgment, order or decree of a court of competent jurisdiction, in effect after exhaustion of all rights of appeal) which substantially impairs the executive's ability to perform his duties or responsibilities; and (iii) continuing willful and unreasonable refusal by the executive to perform the executive's duties or responsibilities (unless such duties or responsibilities are significantly changed without the executive's consent).

        For purposes of the Executive Agreements and the Change in Control Plan, "good reason" is generally defined as: (i) any breach of the Executive Agreements or the Change in Control Plan by Integrys, including, specifically, any breach by Integrys of its agreements contained in the sections regarding duties, compensation and annual compensation adjustments; (ii) the removal of the executive from, or any failure to reelect or reappoint the executive to, any of the positions held with Integrys or the employer on the date of the completion of the merger or any other positions with Integrys or the employer to which the executive will thereafter be elected, appointed or assigned, except in the event that such removal or failure to reelect or reappoint relates to the termination by Integrys of the executive's employment for Cause or by reason of disability; (iii) a good faith determination by the executive that there has been a significant adverse change, without the executive's written consent, in the executive's working conditions or status with Integrys or the employer from such working conditions or status in effect at any time during the 180-day period immediately prior to the completion of the merger, including but not limited to a significant change in the nature or scope of the executive's authority, powers, functions, duties or responsibilities; or (iv) failure by Integrys to obtain a successor's assumption of the obligations under the Executive Agreements and the Change in Control Plan.

        Each of the executive officers are subject to a reduction of their payments under the Executive Agreements or the Change in Control Plan if such payments are subject to the golden parachute excise tax under Section 4999 of the Code to the extent such reduction would result in the executive retaining a greater after-tax amount of such payments.

        Each of the executive officers is also subject to one-year post-termination non-solicitation and non-competition covenants under the Executive Agreements and Change in Control Plan.

        As of the date of this joint proxy statement/prospectus, there are no employment, equity contribution or other agreement, arrangement or understanding between any Integrys executive officer or director, on the one hand, and Integrys or Wisconsin Energy, on the other hand. The merger is not conditioned upon any executive officer or director of Integrys entering into any such agreement, arrangement or understanding.

Table of Contents

        The following tables show the estimated amounts of payments and benefits that each executive officer of Integrys would receive in connection with the merger, assuming the consummation of the merger occurred on June 22, 2015 (the end date, as defined in "The Merger Agreement—Termination of the Merger Agreement—Termination Rights" beginning on page 136) and the employment of the executive officer was terminated without "cause" on such date.

        The first table below, entitled "Potential Change-in-Control Payments to Named Executive Officers", along with its footnotes, sets forth the information required by Item 401(t) of Regulation S-K regarding the compensation payable to Integrys' chief executive officer, chief financial officer and three other most highly compensated executive officers, as determined for purposes of its most recent annual proxy statement, each, which we refer to as a named executive officer, which compensation is subject to an advisory vote of Integrys' shareholders, as described below in "Integrys Proposals—Item 2. The Merger-Related Compensation Proposal" beginning on page 152.

        The second table below, entitled "Potential Change-in-Control Payments to Other Executive Officers", along with its footnotes, shows the compensation payable to Integrys' other executive officers and is not subject to an advisory vote.

        The calculations in the tables below do not include amounts the Integrys executive officers were already entitled to receive or vested as of the date hereof or amounts under contracts, agreements, plans or arrangements to the extent they do not discriminate in scope, terms or operation in favor of executive officers and that are available generally to all of the salaried employees of Integrys.

As described above in "—Individual Employment Arrangements and Executive Change in Control Severance Plan", the cash payments to the named executive officers consist of the sum of (i) the named executive officer's applicable severance multiple (2.99 in the case of Messrs. Schrock, Borgard and Radtke, or 2.0 in the case of Messrs. Schott and Mikulsky) times the sum of his annual base salary and target annual incentive award for the year of termination and (ii) an amount equal to the greater of the actual incentive award for the year of termination to which the named executive officer is entitled or the named executive officer's prorated target annual incentive award. In addition, each named executive officer would also be entitled to reimbursement outplacement assistance not to exceed 15 percent of the named executive officer's annual base salary, continued welfare benefits (until the earlier of the second anniversary of the completion of the merger, the named executive officer's attainment of age 65 (other than Mr. Mikulsky) or the date on which the named executive officer has obtained comparable coverage under a new employer) and reimbursement of up to $10,000 for legal, consulting and/or accounting fees.

As described above in "—Treatment of Integrys Stock Options, RSUs and Deferred Stock Units", the equity amounts consist of the accelerated vesting and cash-out of unvested Integrys stock options, Integrys Time-Based RSUs, Integrys Performance-Based RSUs (assuming the achievement of performance conditions at target level) and Integrys Deferred Stock Units. The amount shown is based on the number of such Equity-Based Awards held by each named executive officer as of June 30, 2014, the latest practicable date to determine such amounts before the filing of this joint proxy statement/prospectus. The amounts shown do not include any such awards that are expected to vest pursuant to their terms between such date and June 22, 2015, and do not attempt to forecast any grants, dividends, additional deferrals or forfeitures of Equity-Based Awards following the date of this joint proxy statement/prospectus. Depending on when the closing date occurs, certain Equity-Based Awards will vest in accordance with their terms. For purposes of this column, the equity award consideration is assumed to equal $69.62, the average closing market price of Integrys common stock on the NYSE over the first five business days following the first public announcement of the transaction on June 23, 2014 and therefore the amounts shown above may be different than the actual amounts the executives will be entitled to receive. Pursuant to the terms of the original award agreements, any named executive officer who has attained age 62, or age 55 and completed 10 years of service, would remain entitled to retain his Equity-Based Awards, whether or not vested, in the event of his termination of employment, regardless of whether the merger transaction occurs.

The above payments are "single-trigger" in nature as they will become payable immediately upon the completion of the merger, (or, in the case of Integrys Deferred Stock Units, will vest on the closing date and will become payable in accordance with their terms) whether or not employment is terminated.

For a description of the treatment of vested Integrys Equity-Based Awards held by Integrys executive officers and directors, please see the section above under "—Treatment of Integrys Stock Options, RSUs and Deferred Stock Units" beginning on page 92.

As described above in the sections entitled "—Pension Restoration and Supplemental Retirement Plan", the nonqualified pension payments to the named executive officers consist of additional service credit for purposes of vesting in supplemental retirement benefits under the SERP.

The above payments are "double-trigger" in nature as they will only be payable in the event of a termination of employment without cause or for good reason following the completion of the merger, or in the event of a termination without cause in anticipation of the completion of the merger. The amounts shown in this column are based on the compensation and benefit levels in effect on August 5, 2014, the latest practicable date to determine such amounts before the filing of this joint proxy statement/prospectus; therefore, if compensation and benefit levels are increased after such date, actual payments to an executive officer may be greater than those provided for above.

The amounts shown in this column do not include any amounts previously accrued and vested under the DCP.

As described above in "—Individual Employment Arrangements and Executive Change in Control Severance Plan", the cash payments to the other executive officers consist of the sum of (i) the executive officer's applicable severance multiple (2.99 in the case of Mr. Verbanac, 2.0 in the case of Messrs. Laakso, Morrow and Cloninger and Ms. Caro, or 1.0 in the case of Mr. Guc and Ms. Kallas) times the sum of his or her annual base salary and target annual incentive award for the year of termination and (ii) an amount equal to the greater of the actual incentive award the executive officer is entitled to for the year of termination or the executive's prorated target annual incentive award. In addition, each executive would also be entitled to reimbursement outplacement assistance not to exceed 15 percent of the executive's annual base salary, continued welfare benefits (until the earlier of the second anniversary of the completion of the merger (or the first anniversary of the completion of the merger, in the case of Mr. Guc and Ms. Kallas), the executive's attainment of age 65 or the date on which the executive has obtained comparable coverage under a new employer and reimbursement of up to $10,000 for legal, consulting and/or accounting fees.

Accounting Treatment

        Wisconsin Energy prepares its financial statements in accordance with accounting principles generally accepted in the United States. The merger will be accounted for by applying the acquisition method, which requires the determination of the acquiror, the acquisition date, the fair value of assets and liabilities of the acquiree and the measurement of goodwill, if any. The accounting guidance for business combinations, which we refer to as ASC 805, provides that in identifying the acquiring entity in a combination effected through an exchange of equity interests, all pertinent facts and circumstances must be considered, including: the relative voting rights of the stockholders of the constituent companies in the combined entity, the composition of the board of directors and senior management of the combined company, the relative size of each company and the terms of the exchange of equity securities in the business combination, including payment of any premium.

        Based on current Wisconsin Energy board members representing a majority of the board of directors of the combined company, as well as the terms of the merger, with Integrys shareholders receiving a premium (as of closing on the last full trading date preceding the merger announcement) over the fair market value of their shares on such date, Wisconsin Energy is considered to be the acquiror of Integrys for accounting purposes. This means that Wisconsin Energy will allocate the purchase price to the fair value of Integrys' assets and liabilities at the acquisition date, with any excess purchase price being recorded as goodwill.


Regulatory Approvals Required for the Merger

        To complete the merger, there are certain filings, notices and waiting periods required in order for Wisconsin Energy and Integrys to obtain required authorizations, approvals or consents from a number of federal and state public utility, antitrust, and other regulatory authorities. These include authorizations, approvals or consents from, or notifications to, the FERC, the FCC, the PSCW, the ICC, the MPSC, and the MPUC. Integrys' subsidiary, Minnesota Energy Resources Corporation, which we refer to as MERC, has also filed a notice with the MPUC and, should the MPUC determine that it has jurisdiction, MERC will be requesting approval. The transaction is also subject to the notification, clearance and reporting requirements under the HSR Act. We are not currently aware of any other material governmental filings, authorizations, approvals or consents that are required prior to their completion of the merger.

        Wisconsin Energy and Integrys currently anticipate completing the merger during the second half of 2015. Although Wisconsin Energy and Integrys believe that they will receive the required authorizations, approvals and consents described below to complete the merger within that time frame, there can be no assurance as to the precise timing of or the ultimate ability of Wisconsin Energy and Integrys to obtain such authorizations, approvals or consents (or any additional authorizations, approvals or consents which may otherwise become necessary). Nor can there be assurance that such authorizations, approvals or consents will be obtained on terms and subject to conditions satisfactory to Wisconsin Energy and Integrys.

101


Table of Contents

        The following is a brief summary of required federal and state regulatory filings/approvals related to the merger.

        The merger is subject to the requirements of the HSR Act, and the rules and regulations promulgated thereunder, which provide that certain acquisition transactions may not be completed until required information has been furnished to the U.S. Department of Justice, which we refer to as the DOJ, and the Federal Trade Commission, which we refer to as the FTC, and until certain waiting periods have been terminated or have expired. Wisconsin Energy and Integrys expect to file their required HSR notification and report forms with the DOJ and FTC during the third quarter of 2014.

        The HSR Act requires the parties to observe a 30-day waiting period after the submission of their HSR filings before consummating their transaction, unless the waiting period is terminated early by the DOJ and FTC. The initial 30-day waiting period can be extended if the DOJ or the FTC issues a Request for Additional Information and Documentary Material, which we refer to as a Second Request, to Wisconsin Energy and Integrys. A Second Request is a request that the parties to a merger or acquisition provide the DOJ or FTC with information, documents and data that allows the agency to further consider whether the proposed transaction violates the federal antitrust laws. The issuance of a Second Request extends the required waiting period to consummate the transaction for an additional 30 days, measured from the time both Wisconsin Energy and Integrys certify that they have complied with the Second Request, unless that waiting period is earlier terminated by the DOJ or FTC, as applicable.

        The expiration or earlier termination of any HSR Act waiting period would not preclude the DOJ or the FTC from challenging the merger on antitrust grounds or from seeking to preliminarily or permanently enjoin the proposed merger. Neither Wisconsin Energy nor Integrys believes that the merger will violate federal antitrust laws, but there can be no guarantee that the DOJ or the FTC will not take a different position. If the merger is not completed within 12 months after the expiration or early termination of the applicable HSR Act waiting period, Wisconsin Energy and Integrys will be required to submit new information to the DOJ and the FTC, and a new HSR Act waiting period will have to expire or be granted early termination before the merger could be completed.

        Wisconsin Energy and Integrys are diversified energy holding companies, each having subsidiaries deemed to be public utilities subject to the jurisdiction of the FERC under the Federal Power Act, which we refer to as the FPA. Section 203 of the FPA requires prior authorization from FERC for certain types of corporate transactions including those resulting in the direct or indirect change of control over a FERC jurisdictional public utility and the acquisition of the securities of a holding company in a holding company system that includes an electric utility company or the merger or consolidation of such a holding company with another holding company that owns an electric utility company. As described above, the merger will be accomplished through a two-step transaction whereby Integrys (and its public utility subsidiaries) will become wholly owned subsidiaries of Wisconsin Energy. Thus, the merger will result in an indirect change of control over the public utility subsidiaries of Integrys (WPS and UPPCO, if the pending sale of UPPCO to an unaffiliated third party has not been completed by the completion of the merger) and the acquisition of the securities of a holding company (Integrys) that owns electric utility companies and consequently, will require prior approval by FERC under Section 203 of the FPA.

102


Table of Contents

        FERC must authorize a merger or transaction under Section 203 of the FPA if it finds that the merger or transaction is consistent with the public interest. FERC has stated that, in analyzing a merger or transaction, it will evaluate the following criteria:

        In addition, in accordance with the Energy Policy Act of 2005, FERC also must find that the merger or transaction will not result in the cross-subsidization by public utility subsidiaries of other subsidiaries or improper encumbrances or pledges of utility assets and, if such cross-subsidization or encumbrances were to occur, whether they are consistent with the public interest.

        FERC will review the foregoing factors to determine whether the merger or transaction is consistent with the public interest. If FERC finds that the merger or transaction would adversely affect competition in wholesale electric power markets, rates for transmission or the wholesale sale of electric energy, or regulation, or that the merger or transaction would result in cross-subsidies or improper encumbrances that are not consistent with the public interest, it may impose remedial conditions intended to mitigate such effects or it may decline to authorize the merger or transaction.

        In the event FERC chooses to impose remedial conditions, Wisconsin Energy and Integrys would then review such conditions in light of the requirements imposed under the merger agreement. Based on FERC precedent, Wisconsin Energy and Integrys believe that the merger should satisfy FERC's merger guidelines as well as its standards regarding cross-subsidization and encumbrances, and that any mitigation conditions imposed by FERC would not have a material adverse effect of the type described by the merger agreement that would permit either company to refuse to accept such conditions. However, there can be no guarantee that FERC will agree with the parties' characterization of FERC precedent or that FERC will not change its analytic framework in a manner adverse to the parties.

        Wisconsin Energy, Integrys and their respective public utility subsidiaries plan to file their application for approval of the merger under Section 203 during the third quarter of 2014. As part of their application, the parties will submit a detailed market power analysis demonstrating that the merger does not raise any significant competitive concerns under FERC's merger guidelines. The application also will demonstrate that the merger satisfies the other criteria considered by FERC in its review. We expect FERC will notice the application for public comment and that third parties will be given 60 days to file comments to or protests of the application.

        FERC is required to rule on a completed merger application not later than 180 days from the date on which the completed application is filed. Such a ruling could either approve or deny the application. FERC may, however, for good cause, issue an order extending the time for its consideration of the merger application by an additional 180 days. If no order is issued within the statutory deadline, then the transaction is deemed to be approved. We expect that FERC will approve the merger within the initial 180-day review period without an evidentiary hearing. However, there is no guarantee that FERC will approve the merger or that it will not extend the time period for its review or not impose remedial conditions on its approval that are unacceptable to the parties in light of the requirements imposed under the merger agreement.

        Aside from the required authorization under Section 203 of the FPA, the merger may require the parties to prepare and submit certain filings under Sections 204 and 205 of the FPA related to financings and market-based rate authorizations of their public utility subsidiaries. None of these filings is a required regulatory approval for completing the merger.

        Under FCC regulations implementing provisions of the Communications Act of 1934, as amended, an entity holding private radio licenses for internal communications purposes generally must obtain the approval of the FCC before the direct or indirect transfer of control or assignment of those licenses. Subsidiaries of Wisconsin Energy and Integrys hold certain FCC licenses for private internal communications and, thus, must obtain prior FCC approval to assign or transfer indirect control of those licenses. The parties believe they will be able to obtain the required FCC approvals.

        The merger is subject to the approval of the PSCW, the ICC and the MPSC, and a notice and information filing with the MPUC, and the approval of the MPUC if it determines it has jurisdiction. The following subheadings contain a brief description of the relevant state regulatory approval requirements for the completion of the merger. While the parties believe they will be able to obtain the required approvals as described below, there is no assurance that the relevant jurisdictions will approve the merger or that such approvals will not include terms, conditions or restrictions that are unacceptable to the parties in light of the requirements imposed under the merger agreement.

        Under the takeover provisions of the Wisconsin public utility holding company law, prior approval of the PSCW is required for the direct or indirect acquisition of more than 10 percent of the outstanding voting securities of a public utility holding company, with the unconditional power to vote those shares. A holding company is defined as any company that owns or controls (directly or indirectly) more than 5 percent of the voting shares of a public utility.

        The electric and gas utility subsidiaries of Wisconsin Energy and one such Integrys subsidiary are public utilities and Integrys and Wisconsin Energy are holding companies subject to regulation by the PSCW. Wisconsin Energy is also seeking approval of certain affiliated interest agreements. Therefore, Wisconsin Energy will require PSCW approval for the transactions contemplated under the merger agreement whereby Wisconsin Energy will acquire 100 percent of the voting shares of Integrys and Integrys and its public utility subsidiaries will become indirect, wholly owned subsidiaries within the Wisconsin Energy holding company system. Wisconsin Energy filed an application for PSCW approval of the merger on August 6, 2014. Under Wisconsin law, in order to approve the merger, the PSCW must find that the proposed transaction is "in the best interests of utility consumers, investors, and the public." The parties believe that the time needed for completing PSCW action on the merger application will be approximately 5-8 months from the date of filing.

        Under the provisions of Michigan's public utility law and MPSC regulations governing mergers and acquisitions, prior approval by the MPSC is required for any person to, "acquire, control, or merge, directly or indirectly, in whole or in part, with a jurisdictional regulated utility . . . ." Michigan's public utility law also provides that, "a jurisdictional regulated utility [shall not] sell, assign, transfer, or encumber its assets to another person without first applying to and receiving the approval of the commission." Certain of the electric utility subsidiaries of Wisconsin Energy and certain of the electric and gas utility subsidiaries of Integrys are subject to regulation by the MPSC regarding retail utility service in Michigan. Thus, the parties will require MPSC approval for the transactions contemplated under the merger agreement whereby Integrys and its utility subsidiaries will become wholly owned subsidiaries of Wisconsin Energy.

Table of Contents

        In considering a proposed transaction, Michigan law requires that the MPSC consider "among other[s]," five specific factors:

        Additionally, the MPSC will review the parties' application, and its supporting testimony and exhibits, to determine whether it meets the requirements of its rules. In granting an order approving a proposed merger, the MPSC may impose reasonable terms and conditions on the transaction to protect: (i) the assets of the jurisdictional regulated utility or (ii) the customers of the jurisdictional regulated utility. The jurisdictional regulated utility may reject the terms and conditions imposed by the commission and not proceed with the transaction.

        The parties filed an application for MPSC approval of the merger on August 6, 2014. Although Michigan law requires technically that the MPSC issue an order either approving or rejecting a proposed transaction within 180 days from the date an application is filed, the law is silent on whether there are any consequences if the MPSC does not act within that time frame. Michigan law does clearly state that the merger may not occur without MPSC approval.

        Under Illinois law, prior approval of the ICC is required for a reorganization transaction involving an Illinois public utility where "reorganization" means any transaction which, regardless of the means by which it is accomplished, results in a change in (i) the ownership of a majority of the voting capital stock of an Illinois public utility; or (ii) the ownership or control of any entity which owns or controls a majority of the voting capital stock of a public utility. Integrys' Peoples Gas and North Shore gas utility subsidiaries are subject to regulation by the ICC. ATC is an Illinois transmission-only public utility, and is subject to regulation by the ICC, as well. Thus, the parties will require ICC approval for the transactions contemplated under the merger agreement whereby Wisconsin Energy will acquire ownership and control of Integrys and indirect ownership and control of its subsidiaries, as well as ownership of a majority of the voting capital stock of ATC.

        In order to approve the merger, the ICC must find that the proposed transaction satisfies the following standards:

105


Table of Contents

        The parties filed an application for ICC approval of the merger on August 6, 2014. The parties also requested approval of an affiliated interest agreement. Under Illinois law, the ICC must act on the merger application within 11 months of the date of the filing. The ICC may extend this date for up to three months to consider amendments to the application and reasonably unforeseeable changes in circumstances.

        Under Minnesota law, prior MPUC approval is required for certain transactions whereby a public utility proposes to (i) sell or acquire operating facilities or systems in Minnesota with a value in excess $100,000; (ii) merge or consolidate with another public utility operating in Minnesota; or (iii) purchase the voting shares of another public utility operating in Minnesota. Integrys' natural gas distribution utility, MERC, is a public utility subject to regulation by the MPUC.

        The parties do not believe under Minnesota law that there is any action necessary by the MPUC for the transactions contemplated under the merger agreement whereby Integrys and its Minnesota Energy Resources Corporation gas utility subsidiary would become indirect, wholly owned subsidiaries of Wisconsin Energy, which is not a Minnesota public utility. However, there is precedent in Minnesota for entities from outside the state to seek MPUC approval for transactions of this type, notwithstanding the lack of clear authority under the Minnesota Public Utilities Act.

        MERC filed a petition for notice and information regarding the merger with the MPUC on August 6, 2014. The parties do not believe that under Minnesota law that there is any action necessary by the MPUC as part of that proceeding. Although the parties believe that MPUC approval is not necessary, there is no guarantee that the MPUC will not take a different position and require approval of the transaction and a finding that the merger is consistent with the public interest, if it asserts jurisdiction. If the MPUC determines to review the merger, we anticipate that such review could reasonably be completed and an order issued within 4-6 months of the date of the filing although the regulatory approval process could take considerably longer if the application is set for an evidentiary hearing or other regulatory processes.


Treatment of Integrys' Existing Debt; Financing

        There are no financing conditions to the merger and the merger is not conditioned upon the completion of the change of control refinancing, as described herein, or obtaining the financing to fund the cash consideration payable in the merger or otherwise consummate the transactions contemplated by the merger agreement.

        In connection with the merger agreement, if Wisconsin Energy submits a written request, Integrys will commence a tender offer to purchase Integrys' 8.00% senior notes due June 1, 2016. To the extent that any of the notes are not validly tendered pursuant to that tender offer, or are tendered but then withdrawn, Integrys will make arrangements with the note holders' trustee to deliver a notice of optional prepayment for the notes, and will deposit funds with the trustee sufficient to prepay the

106


Table of Contents

untendered notes, in accordance with the terms of the indenture documents. This tender offer and notice of prepayment we refer to as the "change of control refinancing."

        Wisconsin Energy will assist Integrys in connection with the change of control refinancing. Amongst other things, Wisconsin Energy will prepare all of the necessary and appropriate documentation. Wisconsin Energy (or one of its subsidiaries) will also provide the amounts to fund the change of control refinancing, will reimburse Integrys' expenses, and will provide limited indemnification to Integrys and certain related parties.

        The change of control refinancing will be conditioned on completion of the merger. The merger is not conditioned on the change of control refinancing, and there are no other financing conditions to the merger.

        Under the merger agreement, Wisconsin Energy represents that it will have sufficient funds to consummate the merger and the other transactions contemplated by the merger agreement. Wisconsin Energy did not provide any commitment letters from lenders when the merger agreement was signed, but has agreed to use its reasonable best efforts to: (i) obtain the necessary funds from lenders to consummate the merger and the other transactions contemplated by the merger agreement; (ii) repay or refinance any outstanding indebtedness that becomes due and payable as a result of the merger; (iii) pay any fees and expenses required to be paid by Wisconsin Energy, merger sub and subsequent merger sub in connection with the merger and the financing; and (iv) satisfy any other payment obligations of Wisconsin Energy, merger sub or subsequent merger sub contemplated by the merger agreement.

        Integrys has agreed to cooperate with Wisconsin Energy in connection with obtaining the financing, within limits specified in the merger agreement.

        Barclays has delivered to Wisconsin Energy a "highly confident" letter with respect to securing financing for the cash consideration of the merger.


Treatment of Integrys Stock Options and Restricted Stock Units

        Upon completion of the merger, outstanding Integrys equity awards, including Integrys stock options, Integrys Time-Based RSUs, Integrys Performance-Based RSUs and Integrys Deferred Stock Units, in each case, whether vested or unvested, will be cancelled. Holders of:

For further discussion of the treatment of Integrys Equity Based-Awards held by directors and executive officers of Integrys, see "The Merger—Interests of Directors and Executive Officers in the Merger—Interests of Directors and Executive Officers of Integrys in the Merger" beginning on page 89.


Dissenters' Rights

        Neither holders of Wisconsin Energy common stock nor holders of Integrys common stock will have any dissenters' rights under the Wisconsin Business Corporation Law or under Wisconsin Energy's or Integrys' articles of incorporation, respectively, in connection with the merger. Neither Wisconsin Energy nor Integrys will independently provide their respective shareholders with any such rights.


NYSE Listing of Wisconsin Energy Common Stock; Delisting and Deregistration of Integrys Common Stock

        Prior to the completion of the merger, Wisconsin Energy has agreed to use its commercially reasonable efforts to cause the shares of Wisconsin Energy to be issued in the merger to be approved for listing on the NYSE. The listing of shares of Wisconsin Energy common stock is also a condition to completion of the merger.

        If the merger is completed, Integrys common stock will cease to be listed on the NYSE and Integrys common stock will be deregistered under the Exchange Act.

        Shares of Wisconsin Energy common stock are expected to continue trading on the NYSE under the symbol "WEC" whether or not the merger is completed.


U.S. Federal Income Tax Consequences

        The following is a discussion of the U.S. federal income tax consequences of the merger to U.S. persons (as defined below) who hold Integrys common stock. For purposes of this discussion, we use the term "U.S. person" to mean a beneficial owner which is:

        Holders of Integrys common stock who are not U.S. persons may have different tax consequences than those described below and are urged to consult their own tax advisors regarding the tax treatment to them under U.S. and non-U.S. laws. The discussion applies only to shareholders who hold Integrys common stock as a capital asset within the meaning of Section 1221 of the Code. The discussion assumes that the merger will be completed in accordance with the merger agreement and as further described in this joint proxy statement/prospectus. This discussion is not a complete description of all of the consequences of the merger relevant to a particular holder, and, in particular, may not address U.S. federal income tax considerations applicable to Integrys shareholders subject to special treatment under U.S. federal income tax law, including, without limitation:

108


Table of Contents

        If a partnership, or other entity or arrangement treated as a partnership for U.S. federal income tax purposes, is an Integrys shareholder, the tax treatment of a partner in the partnership will depend upon the status of that partner and the activities of the partnership. A partner in a partnership that is an Integrys shareholder is strongly urged to consult with its own tax advisor regarding the tax consequences of the merger to it.

        In addition, tax consequences arising under the unearned income Medicare contribution tax pursuant to the Health Care and Education Reconciliation Act of 2010, and under state, local and foreign laws, the alternative minimum tax or under federal laws other than federal income tax laws, are not addressed in this joint proxy statement/prospectus.

        This discussion is based, and the tax opinions referred to in the following paragraphs will be based, upon the provisions of the Code, applicable Treasury Regulations, published positions of the Internal Revenue Service, which we refer to as the IRS, judicial decisions and other applicable authorities, as in effect on the date of the registration statement on Form S-4 of which this joint proxy statement/prospectus is a part or the date of the tax opinions, as the case may be. There can be no assurance that future legislative, administrative or judicial changes or interpretations, which changes or interpretations could apply retroactively, will not affect the accuracy of this discussion or the statements or conclusions set forth in the tax opinions referred to in the following paragraphs. No rulings have been or will be sought from the IRS concerning the tax consequences of the merger, and none of the tax opinions of counsel to be received in connection with the offer and the merger will be binding on the IRS or any court. As such, there can be no assurance that the IRS will not take a contrary position regarding the tax consequences of the offer and the merger described in this discussion or the tax opinions of counsel, or that any such contrary position would not be sustained.

        Tax matters are complicated, and the tax consequences of the offer and the merger to Integrys shareholders will depend on each such shareholder's particular tax situation.

        Integrys shareholders are strongly urged to consult with their own tax advisors regarding the tax consequences of the merger to them, including the effects of U.S. federal, state, local, foreign and other tax laws.

109


Table of Contents

        It is a condition to the obligation of Integrys to complete the merger that Integrys receive a written opinion from Cravath, counsel to Integrys, dated as of the completion of the merger, to the effect that for U.S. federal income tax purposes the initial merger and the subsequent merger, taken together as a single integrated transaction, qualify as a "reorganization" within the meaning of Section 368(a) of the Code. It is a condition to the obligation of Wisconsin Energy to complete the merger that Wisconsin Energy receive a written opinion from Skadden, counsel to Wisconsin Energy, dated as of the completion of the merger, to the effect that for U.S. federal income tax purposes the initial merger and the subsequent merger, taken together as a single integrated transaction, qualify as a "reorganization" within the meaning of Section 368(a) of the Code. Neither Integrys nor Wisconsin Energy currently intends to waive this opinion condition to its obligation to effect the merger. If either Wisconsin Energy or Integrys waives this opinion condition after this registration statement is declared effective by the SEC, and if the U.S. federal income tax consequences of the merger to Integrys shareholders have materially changed, Wisconsin Energy and Integrys will recirculate this joint proxy statement/prospectus and resolicit the votes of Wisconsin Energy stockholders and Integrys shareholders. The opinions will rely on assumptions, representations and covenants contained in representation letters of officers of Wisconsin Energy and Integrys. An opinion of counsel represents counsel's best legal judgment and is not binding on the IRS, or any court, nor does it preclude the IRS from adopting a contrary position. No ruling has been or will be sought from the IRS on the U.S. federal income tax consequences of the merger.

        Accordingly, and on the basis of the foregoing opinions, as a result of the merger qualifying as a "reorganization" within the meaning of Section 368(a) of the Code, for U.S. federal income tax purposes, in general:

110


Table of Contents

        Integrys shareholders who hold their Integrys common stock with differing bases or holding periods should consult their tax advisors with regard to identifying the bases or holding periods of the particular shares of Wisconsin Energy common stock received in the merger.

        Holders of Integrys common stock may be subject to information reporting and backup withholding on any cash payments they receive in the merger. Payments will not be subject to backup withholding if the shareholder (i) is a corporation or comes within certain other exempt categories and, when required, demonstrates this fact or (ii) provides Wisconsin Energy or the exchange agent, as appropriate, with the shareholder's correct taxpayer identification number and completes an IRS Form W-9 or a substitute Form W-9 in which the shareholder certifies that the shareholder is not subject to backup withholding. The taxpayer identification number of an individual is his or her Social Security number.

111


Table of Contents

        Any amounts withheld under the backup withholding rules are not an additional tax and will generally be allowed as a refund or credit against an Integrys shareholder's U.S. federal income tax liability, provided such shareholder timely furnishes the required information to the IRS.

        The discussion of the U.S. federal income tax consequences set forth above is not intended to be a complete analysis or description of all potential U.S. federal income tax consequences of the merger. Moreover, the discussion set forth above does not address tax consequences that may vary with, or are contingent upon, individual circumstances. In addition, the discussion set forth above does not address any non-income tax or any foreign, state or local tax consequences of the merger and does not address the tax consequences of any transaction other than the merger.


Restrictions on Sales of Shares of Wisconsin Energy Common Stock Received in the Merger

        All shares of Wisconsin Energy common stock received by Integrys shareholders in the merger will be freely tradable for purposes of the Securities Act of 1933, as amended, and the Exchange Act, except for shares of Wisconsin Energy common stock received by any Integrys shareholder who becomes an "affiliate" of Wisconsin Energy after completion of the merger.


Litigation Related to the Merger

        Since the June 23, 2014 announcement of the merger agreement, ten purported class action and/or derivative complaints have been filed in state or federal courts by the alleged shareholders of Integrys against Integrys, the individual directors of Integrys and Wisconsin Energy. Two lawsuits were filed in the Circuit Court of Milwaukee County, Wisconsin—a putative class action lawsuit captioned, Amo v. Integrys Energy Group, Inc., et al., Case No. 14CV0053562 (June 25, 2014) (the "Amo Action") and a putative class and derivative action lawsuit captioned Inman v. Schrock, et al., Case No. 14CV007289 (August 29, 2014) (the "Inman Action"). Two putative class action lawsuits were filed in Circuit Court of Cook County, Illinois captioned, Taxman v. Integrys Energy Group, Inc., et al., C.A. No. 2014CH10977 (July 1, 2014) and Curley v. Integrys Energy Group, Inc., et al., C.A. No. 2014CH11508 (July 14, 2014) (the "Illinois Actions"). Three putative class action lawsuits were filed in the Circuit Court of Brown County, Wisconsin: Rubin v. Integrys Energy Group, Inc.,  et al., Case No. 14CV942 (June 27, 2014); Blachor v. Integrys Energy Group, Inc., et al., Case No. 14CV987 (July 8, 2014); Albera v. Integrys Energy Group, Inc., et al., Case No. 2014CV1014 (July 11, 2014) (the "Brown County Actions"). Three lawsuits were filed in the United States District Court for the Northern District of Illinois—two putative class and derivative action lawsuits captioned Steiner v. Budney,  et al., C.A. No. 1:14-CV-06509 (August 22, 2014, amended September 8, 2014) and Collision v. Schrock, et al., C.A. No. 1:14-CV-07011 (September 10, 2014) (the "Steiner and Collision Actions") and a putative class action lawsuit captioned Tri-State Joint Fund v. Integrys Energy Group, Inc., et al., C.A. No. 1:14-CV-06816 (the "Tri-State Action") (September 4, 2014).

        The Amo Action and Illinois Actions allege, among other things, that members of the Integrys Board breached their fiduciary duties in connection with the proposed transaction, and that the merger agreement involves an unfair price, was the product of an inadequate sales process, and contains unreasonable deal protection devices that purportedly preclude competing offers. The complaints further variously allege that Integrys, Wisconsin Energy and/or its acquisition subsidiaries aided and abetted the purported breaches of fiduciary duty. The plaintiffs in these lawsuits seek, among other things, (i) a declaration that the merger agreement was entered into in breach of Integrys' directors' fiduciary duties, (ii) an injunction enjoining the Integrys Board from consummating the merger, (iii) an order directing the Integrys Board to exercise their duties to obtain a transaction which is in the best interests of Integrys' shareholders, (iv) an order granting the class members any benefits allegedly improperly received by the defendants, (v) a rescission of the merger or damages, in the event that it is consummated, and/or (vi) an order directing additional disclosure regarding the merger.

112


Table of Contents

        The Inman Action generally asserts similar claims on behalf of the purported class and derivatively on behalf of Integrys and, in addition, alleges that this registration statement omits material information.

        The Steiner and Collision Actions generally allege that the members of the Integrys Board breached their fiduciary duties by conducting an inadequate sales process that resulted in an unfair price, and by filing a materially deficient registration statement. The Steiner and Collision Actions further allege that Wisconsin Energy aided and abetted those breaches of fiduciary duty. The plaintiffs in the Steiner and Collision Actions, seek, among other things, to enjoin the proposed transaction or an award of damages in the event the merger is consummated. In addition, the Collision complaint alleges that the members of the Integrys Board were unjustly enriched at the expense of Integrys and seeks a court order directing the Integrys board members to disgorge all benefits or compensation obtained as a result of their purported breaches of fiduciary duty.

        The Tri-State Action seeks to enjoin the proposed transaction and alleges that Integrys, the Integrys Board, Wisconsin Energy and Mr. Klappa violated Sections 14(a) and 20(a) of the 1934 Securities Exchange Act and Rule 14a-9 promulgated thereunder. It alleges, among other things, that the registration statement misrepresented or omitted material facts, including material information about the allegedly unfair and conflicted sales process, the inadequate consideration offered in the proposed transaction, and the actual intrinsic value of Integrys.

        On August 6, 2014, Integrys, the Integrys Board and Wisconsin Energy filed a Motion to Dismiss or Stay the Illinois Actions, seeking to dismiss or stay them in deference to the Wisconsin Actions. On August 11, 2014, Integrys, the Integrys Board and Wisconsin Energy filed Motions to Dismiss the Amo Action. Also on August 11, 2014, the plaintiffs in the Wisconsin Actions filed a letter with the courts in which those actions are pending requesting that the Wisconsin Actions be stayed pending resolution of the Illinois Actions. Integrys, the Integrys Board and Wisconsin Energy filed a letter opposing that request on August 12, 2014.

        On August 12, 2014, plaintiffs in the Brown County Actions voluntarily dismissed their suits without prejudice. On August 18, 2014, plaintiff in the Amo Action moved the Wisconsin court to stay his action in favor of the Illinois Actions. Following a hearing on September 4, 2014, the Wisconsin court denied plaintiff's motion to stay the Amo Action.

        On August 27, 2014, plaintiff in the Taxman action filed a motion for leave to amend his complaint seeking to add allegations that the defendants breached their fiduciary duty of candor by filing a materially deficient registration statement.

        On September 30, 2014, the Illinois court dismissed the Illinois Actions in favor of the Amo Action and Inman Action. On October 3, 2014, plaintiff in the Amo Action, joined by plaintiffs from the Brown County Actions, filed an amended purported class action complaint adding allegations that the defendants breached their fiduciary duties by filing a materially deficient registration statement.

        Integrys and Wisconsin Energy believe the allegations of the complaints are without merit and intend to defend these lawsuits vigorously.

THE MERGER AGREEMENT

        This section of this joint proxy statement/prospectus describes the material provisions of the merger agreement, but does not describe all of the terms of the merger agreement and may not contain all of the information about the merger agreement that is important to you. The following summary is qualified by reference to the complete text of the merger agreement, which is attached as Annex A to this joint proxy statement/prospectus and incorporated by reference herein. You are urged to read the full text of the merger agreement because it is the legal document that governs the merger.

        The representations, warranties and covenants contained in the merger agreement were made only for purposes of the merger agreement, as of a specific date. These representations were made solely for the benefit of the parties to the merger agreement and may be subject to important qualifications and limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purpose of allocating risk between parties to the merger agreement rather than the purpose of establishing these matters as facts, and may apply standards of materiality in ways that are different from what may be viewed as material by investors. These representations do not survive completion of the merger. Moreover, information concerning the subject matter of the representations, warranties and covenants may have changed since the date of the merger agreement and subsequent developments or new information qualifying a representation, warranty or covenant may have been included or incorporated by reference into this joint proxy statement/prospectus. As of the date of this joint proxy statement/prospectus, except as set forth in Wisconsin Energy's and Integrys' public disclosures, there are no specific material facts that exist that the parties believe contradict their respective representations, warranties and covenants in the merger agreement. Wisconsin Energy and Integrys will provide additional disclosure in their public reports to the extent they become aware of the existence of any specific material facts that are required to be disclosed under U.S. federal securities laws and might contradict the representations, warranties and covenants contained in the merger agreement. For the foregoing reasons, the representations, warranties and covenants or any descriptions of those provisions should not be read alone, but instead should be read together with the information provided elsewhere in this joint proxy statement/prospectus and in the documents incorporated by reference into this joint proxy statement/prospectus. See "Where You Can Find More Information" beginning on page 174.


The Merger

        The merger agreement provides that, upon the terms and subject to the conditions of the merger agreement, and in accordance with the Wisconsin Business Corporation Law, (i) in the initial merger, the merger sub will merge with and into Integrys, with Integrys continuing as the surviving corporation and a wholly owned subsidiary of Wisconsin Energy, and (ii) in a subsequent merger to occur immediately after the initial merger, Integrys will merge with and into the subsequent merger sub, with the subsequent merger sub continuing as the surviving corporation and a wholly owned subsidiary of Wisconsin Energy. The initial merger and the subsequent merger, taken together, are referred to in this section as the merger.


Effect of the Merger on Capital Stock

        At the effective time of the initial merger, each share of Integrys common stock issued and outstanding immediately prior to the effective time of the initial merger (other than any shares of Integrys common stock owned directly or indirectly by Wisconsin Energy, Integrys, or the merger subs, which will be cancelled at the effective time of the initial merger), will be converted automatically into and shall thereafter represent the right to receive (i) $18.58 in cash, without interest, which we refer to as the cash consideration, and (ii) 1.128 shares of Wisconsin Energy common stock, which we refer to collectively with the cash consideration as the merger consideration, as it may be adjusted as described in this paragraph. Shares of Integrys common stock held by grantor trusts of Integrys will not be cancelled but will instead be converted into the right to receive the merger consideration. The merger

114


Table of Contents

consideration will be adjusted appropriately to fully reflect the effect of any stock dividend, subdivision, reclassification, recapitalization, split, combination, consolidation or exchange of shares, or any similar event, of either Wisconsin Energy common stock or Integrys common stock prior to the completion of the initial merger.

        Wisconsin Energy will not issue fractional shares of Wisconsin Energy common stock in the initial merger. Instead, each holder of shares of Integrys common stock who would otherwise be entitled to receive fractional shares of Wisconsin Energy common stock in the initial merger (after taking into account all shares of Integrys common stock exchanged by such holder) will be entitled to cash, without interest, in lieu of such fractional shares, in an amount equal to such fractional amount multiplied by the average of the volume weighted average price per share of Wisconsin Energy common stock on the New York Stock Exchange on each of the ten consecutive trading days ending with the second complete trading day prior to the completion of the merger.

        At the effective time of the initial merger, each share of common stock of the merger sub issued and outstanding immediately prior to the effective time of the initial merger will be converted into one share of common stock of Integrys, as the surviving corporation in the initial merger.

        At the effective time of the subsequent merger, (i) each share of common stock of the surviving corporation in the initial merger issued and outstanding immediately prior to the effective time of the subsequent merger will be cancelled, and (ii) the shares of the subsequent merger sub will remain outstanding as shares of the surviving corporation in the subsequent merger.


Procedures for Surrendering Integrys Stock

        Prior to the closing of the merger, Wisconsin Energy and Integrys will agree upon and appoint a bank or trust company to act as the exchange agent for the payment of the merger consideration. As promptly as practicable (and no later than two business days) following the completion of the initial merger, the exchange agent will mail to each registered holder of a certificate or certificates that, immediately prior to the completion of the merger, represented outstanding shares of Integrys common stock a form of letter of transmittal for the surrender of such certificate or certificates to the exchange agent for cancellation, and instructions for use thereof.

        Upon surrender of a certificate formerly representing shares of Integrys common stock to the exchange agent for cancellation, together with the letter of transmittal, duly completed and validly executed, and any other documents as may reasonably be required by the exchange agent, the holder of such certificate will be entitled to receive, in exchange for the shares of Integrys common stock represented by such certificate, (i) $18.58 in cash, without interest, per share, (ii) 1.128 shares of Wisconsin Energy common stock per share, and (iii) any cash in lieu of fractional shares of Wisconsin Energy common stock that the holder has the right to receive. Until properly surrendered to the exchange agent, each certificate that represented shares of Integrys common stock prior to the completion of the merger will, following the completion of the initial merger, be deemed to represent only the right to receive the merger consideration. No interest will be paid or will accrue on any consideration or any cash payable to holders of certificates upon surrender of the certificates. The shares of Wisconsin Energy common stock to be issued in the merger may be in the form of a certificate or in book-entry form through a direct registration system.

PLEASE DO NOT SUBMIT YOUR INTEGRYS STOCK CERTIFICATES FOR EXCHANGE UNTIL YOU RECEIVE A LETTER OF TRANSMITTAL AND TRANSMITTAL INSTRUCTIONS FROM THE EXCHANGE AGENT.

115


Table of Contents

        If you own shares of Integrys common stock in book-entry form, you will not need to submit stock certificates representing such shares to the exchange agent. However, the registered holder of such shares will need to deliver a duly completed and validly executed letter of transmittal to the exchange agent in order to receive the merger consideration.


Treatment of Equity-Based Awards

        Each Integrys stock option that is outstanding immediately prior to completion of the merger, whether vested or unvested, will fully vest immediately prior to the completion of the merger and will be cancelled in exchange for the right to receive a cash payment equal to the number of shares of Integrys common stock subject to the Integrys stock option multiplied by the excess of the equity award consideration over the exercise price per share of such Integrys stock option (together with any interest on such amount required to be paid in accordance with the terms of the applicable Integrys stock option award agreement and less any applicable withholding taxes).

        Each Integrys Time-Based RSU that is outstanding immediately prior to the completion of the merger, whether vested or unvested, will fully vest immediately prior to the completion of the merger and will be cancelled in exchange for the right to receive a cash payment from the surviving corporation equal to the number of shares of Integrys common stock subject to the Integrys Time-Based RSU multiplied by the equity award consideration, together with any dividends credited to such Integrys Time-Based RSU (together with any interest on such amount required to be paid in accordance with the terms of the applicable Integrys restricted stock unit award agreement and less any applicable withholding taxes).

        Each Integrys Performance-Based RSU that is outstanding immediately prior to the completion of the merger, whether vested or unvested, will vest at the completion of the merger (i) at the greater of the applicable target performance level and the projected actual performance level, if the completion of the merger occurs prior to the completion of the performance period applicable to such Integrys Performance-Based RSU or (ii) at the performance level determined in accordance with the terms of the Performance-Based RSU award agreement, if the completion of the merger occurs on or following the completion of the performance period applicable to such Integrys Performance-Based RSU, and in either case, will be cancelled in exchange for the right to receive a cash payment from the surviving corporation equal to the number of shares of Integrys common stock subject to the vested portion of the Integrys Performance-Based RSU multiplied by the equity award consideration, together with any dividends credited to such Integrys Performance-Based RSU (together with any interest on such amount required to be paid in accordance with the terms of the applicable Integrys restricted stock unit award agreement and less any applicable withholding taxes).

        Each outstanding Integrys Deferred Stock Unit, whether vested or unvested, will be cancelled in exchange for the right to receive a cash payment from the surviving corporation equal to the number of shares of Integrys common stock subject to such Integrys Deferred Stock Unit immediately prior to the completion of the merger multiplied by the equity award consideration, together with any dividends credited to such Integrys Deferred Stock Unit and less any applicable withholding taxes, payable in accordance with the terms of the Integrys Deferred Compensation Plan.

        The merger will not affect Wisconsin Energy's stock options, restricted stock or other equity awards. All such awards will remain outstanding subject to the same terms and conditions that are applicable prior to the merger.

Post-Merger Governance of Wisconsin Energy; Headquarters; Community Involvement

        Wisconsin Energy will take all necessary action, effective upon completion of the initial merger, to increase the size of the Wisconsin Energy Board to twelve directors, consisting of (i) nine directors from the Wisconsin Energy Board prior to the merger, and (ii) three directors who served on the Integrys Board immediately prior to the initial merger. As of the date of this joint proxy statement/prospectus, the Wisconsin Energy Board consists of nine directors and all nine directors are expected to remain on the Wisconsin Energy Board following the completion of the merger. The three directors serving on the Integrys Board will be selected by Integrys in consultation with Wisconsin Energy, provided that such directors satisfy the New York Stock Exchange independence requirements and the FERC interlocking directorship requirements and that Wisconsin Energy's corporate governance guidelines are taken into account.

        Wisconsin Energy has agreed to take all necessary action, effective upon completion of the initial merger, to cause (i) its corporate headquarters and principal executive offices to be located in metropolitan Milwaukee, Wisconsin, and (ii) to have operational headquarters in Milwaukee, Wisconsin, Chicago, Illinois and Green Bay, Wisconsin.

        Upon completion of the initial merger, Wisconsin Energy has agreed to maintain historic levels of community involvement and charitable contributions in Integrys' and its subsidiaries' existing service territories following the merger.


Completion of the Merger

        Unless Wisconsin Energy and Integrys agree to another date, the parties are required to complete the merger on the second business day after satisfaction or waiver of all the conditions described under "Conditions to Completion of the Merger" below. The merger will be effective at the time the certificate of merger is filed with the Department of Financial Institutions of the State of Wisconsin.


Conditions to Completion of the Merger

        The obligations of each of Wisconsin Energy and Integrys to complete the merger are subject to the satisfaction of the following conditions:

117


Table of Contents

        In addition, the obligation of Wisconsin Energy to complete the initial merger is subject to the satisfaction of the condition that no legal restraint is in effect, and no proceeding is pending before any governmental entity seeking to impose any condition that, individually or in the aggregate, has resulted in or would reasonably be expected to result in a "parent regulatory material adverse effect." A "parent regulatory material adverse effect" is defined to mean any material adverse effect on the business, properties, financial condition or results of operations of Wisconsin Energy and its subsidiaries or of Integrys and its subsidiaries, in each case, taken as whole, except that, for purposes of determining whether an effect would constitute a parent regulatory material adverse effect, Wisconsin Energy and its subsidiaries, taken as a whole, will be deemed to be a consolidated group of entities the size and scale of Integrys and its subsidiaries, taken as whole.


Representations and Warranties

        Each of Wisconsin Energy and Integrys has made representations and warranties with respect to itself and its subsidiaries regarding, among other things:

118


Table of Contents

        For Wisconsin Energy, the merger agreement contains additional representations and warranties regarding access to sufficient funds to consummate the merger, ownership of Integrys common stock and, with respect to the merger subs, the authority of the merger subs to enter into a joinder agreement to become parties to the merger agreement, the ownership of the merger subs and no prior business activities of the merger subs.

        For Integrys, the merger agreement contains additional representations and warranties regarding compliance with derivatives trading policies, inapplicability of state takeover laws and ownership of Wisconsin Energy common stock.

119


Table of Contents

        The representations and warranties noted above are subject to qualifications and limitations agreed to by Wisconsin Energy and Integrys, including being qualified by confidential disclosures agreed upon by the parties, in connection with negotiating the terms of the merger agreement. Many of the representations and warranties in the merger agreement are qualified by a "material adverse effect" standard—that is, they will not be deemed to be untrue or incorrect unless the failure to be true or correct, individually or in the aggregate, would reasonably be expected to have a material adverse effect.

        For purposes of the merger agreement, a "material adverse effect" with respect to any person means any fact, circumstance, effect, change, event or development that materially adversely affects the business, properties, financial condition or results of operations of such person and its subsidiaries, taken as a whole, excluding any effect (except as noted below with respect to disproportionate effects) to the extent resulting from or arising out of:

120


Table of Contents

No Solicitation

        Each of Wisconsin Energy and Integrys respectively will not, and will not authorize or permit any of its affiliates to, and will instruct, and will cause its affiliates to instruct, its and their respective directors, officers or employees or any of their respective investment bankers, accountants, attorneys or other advisors, agents or representatives, which we collectively refer to as representatives, not to, directly or indirectly:

        Each of Wisconsin Energy and Integrys respectively will, and will cause its affiliates and its and their respective representatives to, immediately cease and cause to be terminated all existing discussions or negotiations with any person conducted through the date of the merger agreement with respect to any takeover proposal, or any inquiry or proposal that may reasonably be expected to lead to a takeover proposal, request the prompt return or destruction of all confidential information previously furnished and immediately terminate all physical and electronic dataroom access previously granted to any such person or its representatives.

        Notwithstanding the restrictions described above, at any time prior to obtaining the Wisconsin Energy stockholder approval or the Integrys shareholder approval, as applicable, in response to a bona fide written takeover proposal that the subject party's board determines in good faith (after consultation with outside legal counsel and a financial advisor of nationally recognized reputation) constitutes or would reasonably be expected to lead to a superior proposal (as defined below), and which was not solicited by the party, its affiliates or representatives, was made after the date of the merger agreement and did not otherwise result from a breach of the party's no solicitation obligation under the merger agreement, the party, and its representatives at the request of the party, may, subject to certain notice requirements in connection with a superior proposal discussed below, (i) furnish information with respect to itself and its subsidiaries to the person and its representatives making the takeover proposal (A) provided such information has previously been provided to the other party or is provided to the other party prior to or concurrently with provision to the person making the takeover proposal and (B) pursuant to a customary confidentiality agreement, which we refer to as a takeover proposal confidentiality agreement, not less restrictive of such person than the confidentiality agreement between Wisconsin Energy and Integrys, dated as of March 6, 2014, and (ii) participate in discussions regarding the terms of the takeover proposal and the negotiation of such terms with, and only with, the person making the takeover proposal and its representatives.

        In addition to the obligations in the two paragraphs above, each company will promptly (and in any event within 48 hours) advise the other party orally and in writing of any takeover proposal, the

material terms and conditions of any such takeover proposal (including any changes thereto) and the identity of the person making the takeover proposal. The subject company will keep the other party informed in all material respects on a current basis of the terms and status (including any change to the terms) of any takeover proposal.

        Nothing contained in the no solicitation and related board recommendation provisions of the merger agreement, as applicable to each party, will prohibit either party from (i) complying with Rule 14d-9 and Rule 14e-2 promulgated under the Exchange Act or (ii) making any disclosure to its shareholders, if in the good faith judgment of the subject company's board (after consultation with outside legal counsel) failure to so disclose would be inconsistent with its obligations under applicable law, provided however that in no event will the subject company or the subject company's board or any committee thereof take, or agree or resolve to take, any action prohibited by the no solicitation and related board recommendation provisions of the merger agreement, as applicable to each party.

        A "takeover proposal" means any proposal or offer (whether or not in writing), with respect to any (i) merger, consolidation, share exchange, other business combination, recapitalization, liquidation, dissolution or similar transaction involving the party or any of its subsidiaries, (ii) sale, lease, contribution or other disposition, directly or indirectly (including by way of merger, consolidation, share exchange, other business combination, partnership, joint venture, sale of capital of or other equity interests in a party subsidiary or otherwise) of any business or assets of a party or its subsidiaries representing 20 percent or more of its consolidated revenues, net income or assets of the party and its subsidiaries, taken as a whole, (iii) issuance, sale or other disposition, directly or indirectly, to any person (or the shareholders of any person) or group of securities (or options, rights or warrants to purchase, or securities convertible into or exchangeable for, such securities) representing 20 percent or more of the voting power of the party, (iv) transaction (including any tender offer or exchange offer) in which any person (or the shareholders of any person) will acquire (in the case of a tender offer or exchange offer, if consummated), directly or indirectly, beneficial ownership, or the right to acquire beneficial ownership, or formation of any group which beneficially owns or has the right to acquire beneficial ownership of, 20 percent or more of any class of equity securities or (v) any combination of the foregoing (in each case with respect to Wisconsin Energy, other than the merger, and in each case with respect to Integrys, other than the merger and the Integrys sale transactions).

        A "superior proposal" means any bona fide written superior proposal from any person (with references in the definition of "takeover proposal" to 20 percent being replaced by references to 50 percent) (i) on terms which the subject board determines in good faith (after consultation with outside legal counsel and a financial advisor of nationally recognized reputation), if consummated, to be more favorable from a financial point of view to the holders of common stock than the merger, taking into account all the terms and conditions of such proposal (including the legal, financial, regulatory, timing and other aspects of the proposal, the identity of the person making the proposal and any financing required for such proposal, the ability of the person making such proposal to obtain such required financing and the level of certainty with respect to such required financing) and this merger agreement (including any changes proposed by the other party to the terms of the merger agreement) and (ii) that is reasonably likely to receive all required governmental approvals on a timely basis and otherwise reasonably capable of being completed on the terms proposed, taking into account all financial, regulatory, legal and other aspects of such proposal.

In determining whether to terminate the merger agreement under the pre-shareholder approval takeover termination right, the subject board will take into account all written or oral information, opinions or analyses submitted by or on behalf of the other party, and any changes to the terms of the merger agreement proposed by the other party in response to a notice of such termination.

        In addition, notwithstanding the restrictions above, before the Wisconsin Energy stockholder approval is obtained, in the case of the Wisconsin Energy Board, or the Integrys shareholder approval is obtained, in the case of the Integrys Board, the Wisconsin Energy Board or the Integrys Board, as the case may be, may effect an adverse recommendation change (i) as a result of the occurrence of an intervening event (as defined below) or (ii) in response to a superior proposal, in each case if:

Wisconsin Energy and Integrys will use their respective reasonable best efforts to obtain all such required consents or nonactions from such governmental entities and eliminate each and every other impediment that may be asserted by such governmental entities pursuant to any antitrust law or in connection with granting required statutory approvals for Wisconsin Energy and Integrys, respectively, in each case with respect to the initial merger, so as to enable the closing of the initial merger to occur as soon as reasonably possible.

        Subject to restrictions with respect to actions resulting, or reasonably expected to result in a parent regulatory material adverse effect, as defined and discussed below, Wisconsin Energy and Integrys each will, and will cause their respective subsidiaries to, undertake any effort or take any action (including accepting terms, conditions, liabilities, obligations, commitments or sanctions and proposing, negotiating, committing to and effecting, by consent decree, hold separate order or otherwise, the sale, divestiture, licensing or disposition of assets or businesses of Wisconsin Energy or Integrys or their respective subsidiaries) necessary or required in order to obtain the required statutory approvals for Wisconsin Energy and Integrys, respectively.

Table of Contents

        In connection with and without limiting the generality of the foregoing, each of Wisconsin Energy and Integrys will, among other things:

        Notwithstanding the obligations described in this section, Wisconsin Energy has the primary responsibility for scheduling and conducting any meeting with any governmental entity, coordinating and making any applications and filings with, and resolving any investigation or other inquiry of, any agency or other governmental entity, required statutory approvals for Wisconsin Energy and Integrys, respectively, required consents, consents, permits and other approvals and confirmations from any governmental entity necessary, proper or advisable to consummate the transactions contemplated by the merger agreement; provided, however, that Wisconsin Energy agrees to consult with Integrys reasonably in advance of taking any such action. The parties shall promptly notify the other of (i) any notice or other communication from any person alleging that such person's consent is or may be required in connection with the transactions contemplated by the merger agreement, (ii) any notice or other communication from any governmental entity in connection with the transactions contemplated by the merger agreement and (iii) any actions, suits, claims, litigations, investigations or proceedings commenced or, to its knowledge, threatened against, relating to or involving or otherwise affecting either party or its subsidiaries that, in any such case, relate to the merger agreement or the transactions contemplated by the merger agreement.

Access to Information; Confidentiality

        Until completion of the merger, each of Wisconsin Energy and Integrys will afford the other party and its representatives reasonable access on certain conditions to all of its and its subsidiaries' respective properties, books, contracts, commitments, personnel and records. Each of Wisconsin Energy and Integrys will keep confidential any nonpublic information in accordance with the terms of the confidentiality agreement between Wisconsin Energy and Integrys, dated as of March 6, 2014.


Indemnification, Exculpation and Insurance

        All rights to indemnification, advancement of expenses and exculpation now existing in favor of the current or former directors, officers or employees of Integrys and its subsidiaries will survive the merger and continue in full force and effect after completion of the merger. For six years after the merger, Wisconsin Energy will cause the surviving corporation to procure the provision of officers' and directors' liability insurance for acts or omissions occurring prior to the merger becoming effective, covering each person currently covered by Integrys' or its subsidiaries' officers' and directors' liability insurance policy on terms at least as favorable as those of the applicable policy as of the date of the merger agreement. In the event that the premiums for such liability insurance exceed 300 percent of the aggregate annual premium currently paid, Wisconsin Energy will provide or cause to be provided a policy with the best coverage available at a cost up to but not exceeding 300 percent of the current aggregate annual premium. In lieu of the insurance described in the two preceding sentences, prior to the completion of the initial merger, Wisconsin Energy may, in consultation with Integrys, purchase a "tail" directors' and officers' liability insurance policy and fiduciary liability insurance policy for Integrys, its subsidiaries and their current and former directors and officers who are currently covered by the directors' and officers' and fiduciary liability insurance coverage maintained by Integrys and its subsidiaries on terms that are at least as favorable as the those of the applicable policy in effect on the date of the merger agreement, subject to the same 300 percent premium cap described in the previous sentence.


Fees and Expenses

        Each of Wisconsin Energy and Integrys has agreed to pay its own fees and expenses incurred in connection with the merger and the other transactions contemplated by the merger agreement, except in connection with a party's payment of a termination fee as described in "Termination of the Merger Agreement," below, in greater detail.


Certain Tax Matters

        The parties intend that the initial merger and the subsequent merger, taken together as a single integrated transaction, qualify as a "reorganization" within the meaning of Section 368(a) of the Code in which Integrys is to be treated as merging directly with and into the subsequent merger sub with Integrys common stock converted into the right to receive the merger consideration, and (ii) the merger agreement is intended to be, and is adopted as, a "plan of reorganization." In addition, each of Wisconsin Energy, Integrys and the merger subs agrees to:

131


Table of Contents

        To the extent necessary, Wisconsin Energy, Integrys and the merger subs will work together in good faith to effect the combination contemplated by the merger agreement using an alternative structure that would be tax-free to the extent of the stock consideration in the event that (i) the merger will not qualify as a "reorganization" within the meaning of Section 368(a) of the Code, (ii) favorable tax opinions are not issued with respect to the transactions contemplated by the merger agreement or (iii) Wisconsin Energy reasonably determines that the subsequent merger may result in a constructive termination of American Transmission Company LLC under Section 708 of the Code.


Transaction Litigation

        Subject to applicable law, Integrys will keep Wisconsin Energy reasonably informed of any litigation against Integrys or its directors relating to the initial merger and the other transactions contemplated by the merger agreement, and Integrys agrees that it will not agree to any settlement of such litigation without Wisconsin Energy's prior consent (such consent not to be unreasonably withheld, conditioned or delayed). Wisconsin Energy will keep Integrys reasonably informed of any litigation against Wisconsin Energy or its directors relating to the initial merger and the other transactions contemplated by the merger agreement.


Section 16 Matters

        Each of Wisconsin Energy, Integrys and the merger sub will take, prior to completion of the initial merger, all steps as may be required to exempt from the reporting requirements of Section 16(a) of the Exchange Act, under Rule 16b-3 promulgated under the Exchange Act, any dispositions of Integrys common stock (including derivative securities thereof) resulting from the initial merger and the other transactions contemplated by the merger agreement by individuals otherwise subject to such reporting requirements immediately prior to the completion of the initial merger and acquisitions of Wisconsin Energy common stock (including derivative securities thereof) resulting from the initial merger and the other transactions contemplated by the merger agreement by each individual who may become or is reasonably expected to become otherwise subject to such reporting requirements.


Financing

        Wisconsin Energy will use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to arrange and obtain funds from lenders, along with cash on hand, to (i) permit Wisconsin Energy and the merger subs to consummate the merger and the transactions contemplated by the merger agreement on a timely basis, (ii) effect, as required, the repayment or refinancing of any outstanding indebtedness that may become due and payable as a result of the merger, (iii) pay any and all fees and expenses required to be paid by Wisconsin Energy and the merger subs in connection with the merger and the financing and (iv) satisfy all of the other payment obligations of Wisconsin Energy and the merger subs contemplated by the merger agreement.

        Integrys will, and will cause its subsidiaries to, use reasonable best efforts to cause its and their respective representatives to, on a timely basis, provide all reasonable cooperation requested by Wisconsin Energy and/or the lenders that is reasonably necessary and customary to assist Wisconsin Energy in connection with obtaining the financing, provided that such requested cooperation does not unreasonably interfere with the ongoing operations of Integrys and its subsidiaries. Without limiting the generality of the foregoing, such cooperation will in any event include:

        Notwithstanding the requirements above, no obligation of Integrys and its subsidiaries under any certificate, document or agreement delivered by Integrys or its subsidiaries will be effective until the initial merger is effective and none of Integrys or its subsidiaries will be required to take any action under any such certificate, document or agreement that is not contingent upon the closing or that would be effective before the initial merger is effective.


Treatment of Certain Indebtedness

        As soon as reasonably practicable after the receipt of any written request by Wisconsin Energy to do so, Integrys will take the following actions on such terms and conditions that are consistent with the requirements of Integrys' 8.00% senior notes due June 1, 2016, which are referred to as the notes and are subject to the indenture, dated as of October 1, 1999, between Integrys, as the issuer, and

133


Table of Contents

U.S. Bank National Association, as Trustee, which we refer to as the indenture, and otherwise reasonably specified, from time to time, by Wisconsin Energy:

        Wisconsin Energy will assist Integrys in connection with the actions in the bullet points above, which we collectively refer to as the change of control refinancing. Notwithstanding anything to the contrary in the merger agreement, the closing of any change of control refinancing will be conditioned on the occurrence of the closing of the initial merger. The transactions will be funded by amounts provided by Wisconsin Energy or one of its subsidiaries and receipt of such funding will be a condition to any debt tender offer.

        Integrys and its subsidiaries will not be required to take any action in violation of law or the indenture in connection with the change of control refinancing. Integrys will provide, will cause its subsidiaries to, and will use its reasonable best efforts to cause their respective representatives to, provide all cooperation reasonably requested by Wisconsin Energy in connection with the change of control refinancing.

        Wisconsin Energy will:

        At or immediately prior to the initial merger becoming effective, Integrys will use its reasonable best efforts to deliver to Wisconsin Energy copies of payoff letters, in a form reasonably acceptable to Wisconsin Energy, from the administrative agent under Integrys' existing credit facilities and will make arrangements for the release of all liens and other security over Integrys' and its subsidiaries' properties and assets, if any, securing its obligations under such existing credit facilities that are being prepaid and terminated on the completion of the merger, together with the return of any collateral in the possession of the relevant administrative agent or the collateral agent effective as of the time the merger becomes effective.


Employee Benefits Matters

        The merger agreement provides that, for the one year period following the completion of the merger, each employee of Integrys and its subsidiaries who remains employed by Wisconsin Energy or the surviving corporation or any of their subsidiaries following the completion of the merger (each such employee we refer to as a company employee), and who is not covered by a union contract, will be provided with (i) compensation and benefits, in each case, that are no less favorable than the compensation and benefits provided to the company employee immediately prior to the completion of the merger and (ii) severance and separation benefits that are no less favorable than the severance and

134


Table of Contents

separation benefits provided to the company employee immediately prior to the completion of the merger. Under the merger agreement, Wisconsin Energy, the surviving corporation and their subsidiaries may not amend or otherwise adjust any such company employee's health, dental, vision or disability benefits any time prior to December 31 of the year following the year in which the completion of the merger occurs, to the extent that any such amendment or adjustment would subject such company employee to any additional costs.

        Wisconsin Energy and the surviving corporation or its subsidiaries, as applicable, will continue to honor the union contracts and employment, severance, retention, termination and change in control plans, policies and arrangements of Integrys and will provide certain union employees covered by Wisconsin Statue § 196.807, to the extent applicable, with at least the same wages and substantially equivalent fringe benefits and other terms and conditions of employment that were provided prior to the completion of the merger.

        The merger agreement also provides that, with certain exception, service credit will be provided to company employees for purposes of vesting, eligibility to participate in and determination of level of benefits under the employee benefit plans of Wisconsin Energy, other than for benefit accruals under any defined benefit plan or frozen benefit plan or vesting under any equity incentive plan.


Dividends

        Under the merger agreement, Wisconsin Energy and Integrys agreed to coordinate with each other regarding the declaration and payment of dividends in respect of their common stock and the record dates and payment dates relating thereto, so to as ensure proper payment to stockholders of quarterly dividends with respect to their respective shares of Wisconsin Energy common stock and Integrys common stock.

        Further, under the merger agreement, the Wisconsin Energy Board agreed to adopt and approve a new dividend policy to take effect upon completion of the initial merger relating to the payment of dividends on the outstanding Wisconsin Energy common stock after completion of the merger. The dividend policy will provide for a quarterly dividend per share of Wisconsin Energy common stock in an amount equal to the quarterly dividend amount paid per share by Integrys on the outstanding Integrys common stock on Integrys' most recent dividend payment date before completion of the initial merger, divided by a dividend exchange ratio. As defined in the merger agreement, the dividend exchange ratio will be calculated by dividing the value of the merger consideration by the average of the volume weighted average price per share of Wisconsin Energy common stock on the NYSE on each of the 10 consecutive trading days ending with the second complete trading day prior to the completion of the merger.


Public Announcements

        Except with respect to effecting an adverse recommendation change under the terms of the merger agreement, Wisconsin Energy and Integrys will consult with each other before issuing, and give each other the opportunity to review and comment upon, any press release or other written public statements with respect to the transactions contemplated by the merger agreement, including the merger, and will not issue any press release or make any such written public statement prior to such consultation, except as required by applicable law, court process or by obligations pursuant to any listing agreement with any national securities exchange or national securities quotation system.


Stock Exchange Listing

        Wisconsin Energy will use its commercially reasonable efforts to cause the shares of Wisconsin Energy common stock to be issued in the initial merger to be approved for listing on the New York Stock Exchange prior to the completion of the initial merger. Integrys will use its commercially

135

reasonable efforts to cooperate with Wisconsin Energy in connection with the foregoing, including providing information reasonably requested by Wisconsin Energy.


Termination of the Merger Agreement

        The merger agreement may be terminated before the consummation of the initial merger by (i) mutual consent or (ii) by either party if:

        Wisconsin Energy must pay a termination fee of $175 million to Integrys if:

136


Table of Contents

        Integrys must pay a termination fee of $175 million to Wisconsin Energy if:


Amendment

        The merger agreement may be amended by the parties at any time before or after receipt of the Wisconsin Energy stockholder approval or the Integrys shareholder approval; provided, however, that (i) no amendment is made to the merger agreement that would adversely affect the rights of the lenders without their consent, (ii) after receipt of the Wisconsin Energy stockholder approval, there will be made no amendment that by law requires further approval by the stockholders of Wisconsin Energy without the further approval of such stockholders, (iii) after receipt of the Integrys shareholder approval, there shall be made no amendment that by law requires further approval by the shareholders of Integrys without the further approval of such shareholders, (iv) no amendment will be made to the

137


Table of Contents

merger agreement after the initial merger becomes effective and (v) except as provided above, no amendment of the merger agreement will require the approval of the stockholders of Wisconsin Energy or the shareholders of Integrys. The merger agreement may not be amended except by an instrument in writing signed on behalf of each of the parties.


Extension; Waiver

        At any time prior to the completion of the initial merger, the parties may (i) extend the time for the performance of any of the obligations or other acts of the other parties, (ii) waive any inaccuracies in the representations and warranties contained in the merger agreement or in any document delivered pursuant to the merger agreement, (iii) subject to amendment, waive compliance with any covenants and agreements contained in the merger agreement or (iv) waive the satisfaction of any of the conditions contained in the merger agreement. No extension or waiver by Wisconsin Energy will require the approval of the stockholders of Wisconsin Energy unless such approval is required by law and no extension or waiver by Integrys will require the approval of the shareholders of Integrys unless such approval is required by law. Any agreement on the part of a party to any such extension or waiver will be valid only if set forth in an instrument in writing signed on behalf of such party. The failure of any party to the merger agreement to assert any of its rights under the merger agreement or otherwise will not constitute a waiver of such rights.

        A termination, amendment, extension or waiver, in order to be effective, will require, in the case of Wisconsin Energy, Integrys or the merger subs, action by its respective board of directors or the duly authorized designee of its board of directors. Termination of the merger agreement prior to the initial merger becoming effective will not require the approval of the stockholders of Wisconsin Energy or the shareholders of Integrys.

INFORMATION ABOUT THE COMPANIES

Wisconsin Energy Corporation

        Wisconsin Energy was incorporated in the state of Wisconsin in 1981 and became a diversified energy holding company in 1986. Wisconsin Energy maintains its principal executive offices in Milwaukee, Wisconsin.

        Wisconsin Energy conducts its operations primarily in two reportable segments: a utility energy segment and a non-utility energy segment. Wisconsin Energy's primary subsidiaries are Wisconsin Electric, Wisconsin Gas and We Power.

        Utility Energy Segment:    Wisconsin Energy's utility energy segment consists of Wisconsin Electric and Wisconsin Gas, operating together under the trade name of "We Energies." We Energies serves approximately 1,128,300 electric customers in Wisconsin and the Upper Peninsula of Michigan. We Energies serves approximately 1,079,800 gas customers in Wisconsin and approximately 445 steam customers in metropolitan Milwaukee, Wisconsin. In addition, Wisconsin Energy has a 26.24 percent equity interest in ATC.

        Non-Utility Energy Segment:    Wisconsin Energy's non-utility energy segment consists primarily of We Power, which owns and leases to Wisconsin Electric generation plants constructed as part of Wisconsin Energy's Power the Future, which we refer to as PTF, strategy. Under the PTF strategy, four power plants have been placed in service and provide approximately 2,320 MW of new generation in Wisconsin, approximately 2,120 MW of which is being leased to Wisconsin Electric under long-term leases. Two unaffiliated entities collectively purchased an approximately 17 percent interest, or 200 MW, in the two coal plants constructed as part of the PTF strategy. The PTF strategy was designed to address Wisconsin Electric's electric supply needs by increasing the electric generating capacity in Wisconsin while allowing Wisconsin Energy to maintain a diversified fuel mix, by including both new coal-fired plants and natural-gas fired plants. Because of the significant investment necessary to construct these generating units, Wisconsin Energy constructed the plants under Wisconsin's Leased Generation Law, which became effective in August 2001 and allows a non-utility affiliate to construct an electric generating facility and lease it to the public utility. For further information about the PTF strategy, please see Wisconsin Energy's Annual Report on Form 10-K for the fiscal year ended December 31, 2013, incorporated herein by reference.

        For the year ended December 31, 2013, Wisconsin Energy had total operating revenues of approximately $4.5 billion and total net income from continuing operations of approximately $577.4 million. For the six months ended June 30, 2014, Wisconsin Energy had total operating revenues of approximately $2.7 billion and total net income from continuing operations of approximately $340.6 million.

        Wisconsin Energy common stock is traded on the NYSE under the symbol "WEC." Wisconsin Energy's principal executive offices are located at 231 West Michigan Street, P.O. Box 1331, Milwaukee, Wisconsin 53201, its telephone number is (414) 221-2345 and its website is www.wisconsinenergy.com.

Record Date; Quorum

        The record date for the Wisconsin Energy special meeting is October 13, 2014. Wisconsin Energy's stockholders of record as of the close of business on that day will receive notice of and will be entitled to vote at the special meeting. As of the record date for the meeting, there were 225,517,341 shares of Wisconsin Energy common stock issued and outstanding and entitled to vote at the meeting. The issued and outstanding shares are held by approximately 38,475 holders of record.

        The presence, in person or by proxy, of a majority of the shares of Wisconsin Energy common stock entitled to vote on the merger agreement is necessary to constitute a quorum at the meeting. Each share of Wisconsin Energy common stock outstanding on the record date entitles its holder to one vote on each of the proposals described above and any other proposals that may properly come before the meeting.

        To determine the presence of a quorum at the meeting, Wisconsin Energy will also count as present at the meeting the shares of Wisconsin Energy common stock present in person but not voting, and the shares of common stock for which Wisconsin Energy has received proxies but with respect to which the holders of such shares have abstained or signed without providing instructions as described in "Solicitation and Revocation of Proxies" below.


Vote Required

        Required Vote to Approve the Share Issuance Proposal (Item 1 on the Wisconsin Energy Proxy Card)

        The affirmative vote of a majority of the votes cast by Wisconsin Energy stockholders as of the record date for the Wisconsin Energy special meeting is required to approve the Share Issuance proposal.

        The affirmative vote of a majority of the issued and outstanding shares of Wisconsin Energy common stock as of the record date for the Wisconsin Energy special meeting is required to approve the Name Change proposal.

        As of the record date for the meeting, Wisconsin Energy's directors and executive officers beneficially owned a total of 2,628,197 shares, or approximately 1.17 percent of the issued and outstanding shares, of Wisconsin Energy common stock. We anticipate that these individuals will vote

143

their shares in favor of the proposals described above, although none of the individuals have entered into any agreements obligating them to do so.


Solicitation and Revocation of Proxies

        If you have delivered a signed proxy card for the Wisconsin Energy special meeting or otherwise voted pursuant to the instructions set forth on the proxy card, you may revoke it at any time before it is voted by:

        The proxy holders will vote as directed on all valid proxies that are received at or prior to the meeting and that are not subsequently revoked. If you complete, date and sign your proxy card but do not provide instructions as to your vote, the proxy holders will vote your shares:

If any other matters are properly presented at the meeting for consideration, the persons named in the proxy card will have discretionary authority to vote your shares on those matters. Wisconsin Energy's board of directors is not aware of any matter to be presented at the meeting other than the proposals described above.

        If you hold shares in "street name" through an intermediary, such as a bank, brokerage firm or other nominee, you will receive voting instructions from the holder of record of your shares. Under the rules of various national and regional securities exchanges, brokers, banks and other fiduciaries may generally vote your shares on routine matters, such as the ratification of an independent registered public accounting firm, even if you provide no instructions, but may not vote on non-routine matters, such as the matters being brought before the special meeting, unless you provide voting instructions. Shares for which a broker does not have the authority to vote are recorded as "broker nonvotes," are not counted in the vote by stockholders but will count for purposes of a quorum. We therefore encourage you to provide directions to your broker as to how you want your shares voted on all matters to be brought before the special meeting. You should do this by carefully following the instructions your broker gives you concerning its procedures. If you hold shares in "street name" and wish to change your vote at any time, you must contact your broker.

        If you are a participant in Stock Plus or own shares through investments in the Wisconsin Energy Common Stock ESOP Fund in Wisconsin Energy's 401(k) plan, your proxy will serve as voting instructions for your shares held in those plans. The administrator for Stock Plus and the trustee for the 401(k) plan will vote your shares as you direct. If a proxy is not returned for shares held in Stock Plus, the administrator will not vote those shares. If a proxy is not returned for shares held in the 401(k) plan, the trustee will vote those shares in the same proportion that all shares in the Wisconsin Energy Common Stock ESOP Fund for which voting instructions have been received, are voted.

        Wisconsin Energy will bear the cost of soliciting proxies from its stockholders. Wisconsin Energy will solicit stockholder votes by mail, and may also solicit certain stockholders by other means of communication, including telephone or in person. If any directors, officers and employees of Wisconsin Energy solicit your vote in person, by telephone, or by other means of communication, they will receive

144


Table of Contents

no additional compensation for doing so. Wisconsin Energy will reimburse brokerage firms and other persons representing beneficial owners of shares for their reasonable expenses in forwarding solicitation material to those beneficial owners.

        In addition, Wisconsin Energy has engaged a professional proxy solicitation firm, Morrow & Co., LLC, to assist in soliciting proxies for a fee of $17,500. In addition, Wisconsin Energy will reimburse Morrow & Co., LLC for its reasonable disbursements.


How to Vote Your Shares

If you are a "street name" stockholder (i.e., you own your shares in the name of a broker, bank, or other fiduciary), you should refer to the information you receive from your broker to see which voting methods are available to you. Please note, if you are a street name stockholder, and wish to vote in person at the special meeting, you must obtain a proxy executed in your favor from your broker to be able to vote at the special meeting. If you wish to vote through the Internet or by telephone, please follow the instructions on your proxy card or the information forwarded to you by your bank or broker, as applicable. The Internet and telephone voting facilities will close at 10:59 p.m., Central time, on November 20, 2014.

WISCONSIN ENERGY PROPOSALS

Item 1.    The Share Issuance Proposal

(Item 1 on Wisconsin Energy Proxy Card)

        It is a condition to completion of the merger that Wisconsin Energy issue shares of Wisconsin Energy common stock in the merger. When the merger becomes effective, each share of Integrys common stock outstanding immediately before the merger will be converted into the right to receive 1.128 shares of Wisconsin Energy common stock and $18.58 in cash. This exchange ratio is fixed and will not be adjusted to reflect stock price changes prior to closing.

        Under the NYSE Listed Company Manual, a company listed on the NYSE is required to obtain stockholder approval prior to the issuance of common stock, or of securities convertible into or exercisable for common stock, in any transaction or series of related transactions if the number of shares of common stock to be issued is, or will be upon issuance, equal to or in excess of 20 percent of the number of shares of common stock outstanding before the issuance of the common stock or of securities convertible into or exercisable for common stock. If the merger is completed, it is currently estimated that Wisconsin Energy will issue or reserve for issuance approximately 90 million shares of Wisconsin Energy common stock in connection with the merger. On an as-converted basis, the aggregate number of shares of Wisconsin Energy common stock to be issued in the merger will exceed 20 percent of the shares of Wisconsin Energy common stock outstanding before such issuance; for this reason, Wisconsin Energy must obtain the approval of Wisconsin Energy stockholders for the issuance of shares of Wisconsin Energy common stock to Integrys shareholders in connection with the merger.

        Wisconsin Energy is asking its stockholders to approve the Share Issuance proposal. The issuance of these securities to Integrys shareholders is necessary to effect the merger and the approval of the Share Issuance proposal is required for completion of the merger.

        The Wisconsin Energy Board recommends a vote FOR the Share Issuance proposal (Item 1).

Item 2.    The Name Change Proposal

(Item 2 on Wisconsin Energy Proxy Card)

        Wisconsin Energy is proposing to change the corporate name of Wisconsin Energy from "Wisconsin Energy Corporation" to "WEC Energy Group, Inc." upon completion of the merger. To effect this change, Wisconsin Energy would amend its restated articles of incorporation. Wisconsin Energy is seeking the approval of its stockholders to change Wisconsin Energy's name to "WEC Energy Group, Inc." upon completion of the merger. The text of the proposed articles of amendment to Wisconsin Energy's restated articles of incorporation to effect the Name Change is attached to this joint proxy statement/prospectus as Annex D.

        The Name Change proposal is conditioned on approval of the Share Issuance proposal and on completion of the merger.

        The Wisconsin Energy Board recommends a vote FOR the Name Change proposal (Item 2).

Item 3.    The Wisconsin Energy Meeting Adjournment Proposal

(Item 3 on Wisconsin Energy Proxy Card)

        The Wisconsin Energy special meeting may be adjourned to another time or place, if necessary or appropriate, to permit, among other things, further solicitation of proxies if necessary to obtain additional votes in favor of the Share Issuance proposal.

146


Table of Contents

        If, at the Wisconsin Energy special meeting, the number of shares of Wisconsin Energy common stock present or represented and voting in favor of the Share Issuance proposal is insufficient to approve the Share Issuance proposal, Wisconsin Energy intends to move to adjourn the Wisconsin Energy special meeting in order to enable the Wisconsin Energy Board to solicit additional proxies for approval of the Share Issuance proposal.

        In the Wisconsin Energy Meeting Adjournment proposal, Wisconsin Energy is asking its stockholders to authorize the holder of any proxy solicited by the Wisconsin Energy Board to vote in favor of granting discretionary authority to the proxy holders, and each of them individually, to adjourn the Wisconsin Energy special meeting to another time and place for the purpose of soliciting additional proxies. If the Wisconsin Energy stockholders approve the Wisconsin Energy Meeting Adjournment proposal, Wisconsin Energy could adjourn the Wisconsin Energy special meeting and any adjourned session of the Wisconsin Energy special meeting and use the additional time to solicit additional proxies, including the solicitation of proxies from Wisconsin Energy stockholders who have previously voted.

        The Wisconsin Energy Board recommends a vote FOR the Wisconsin Energy Meeting Adjournment proposal (Item 3).


Other Matters to Come Before the Meeting

        No other matters are intended to be brought before the meeting by Wisconsin Energy, and Wisconsin Energy does not know of any matters to be brought before the meeting by others. If, however, any other matters properly come before the meeting, the persons named in the proxy will vote the shares represented thereby in accordance with the judgment of management on any such matter.

        To determine the presence of a quorum at the meeting, Integrys will also count as present at the meeting the shares of Integrys common stock present in person but not voting, and the shares of common stock for which Integrys has received proxies but with respect to which the holders of such shares have abstained or signed without providing instructions as described in "Solicitation and Revocation of Proxies" below.

Because the vote on the Merger-Related Compensation proposal is advisory only, it will not be binding on either Integrys or Wisconsin Energy. Accordingly, if the merger agreement is adopted and the merger is completed, the compensation will be payable, subject only to the conditions applicable thereto, regardless of the outcome of the non-binding, advisory vote of Integrys shareholders.

        Required Vote to Approve the Integrys Meeting Adjournment Proposal (Item 3 on the Integrys Proxy Card)

and the merger. In particular, holders of Integrys common stock are directed to the merger agreement, a copy of which is attached as Annex A to this joint proxy statement/prospectus.

        Approval of the Merger proposal is required for completion of the merger.

        The affirmative vote of a majority of the shares of Integrys common stock outstanding on the record date for the Integrys special meeting is required to approve the Merger proposal

        The Integrys Board recommends a vote FOR the Merger proposal (Item 1).

Item 2.    The Merger-Related Compensation Proposal

(Item 2 on Integrys Proxy Card)

        As required by Section 14A of the Exchange Act of 1934 and the applicable SEC rules issued thereunder, which were enacted pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank Act, Integrys is required to submit a proposal to Integrys shareholders for a non-binding, advisory vote to approve the payment by Integrys of certain compensation to the named executive officers of Integrys that is based on or otherwise relates to the merger. This proposal, which Integrys refers to as the Merger-Related Compensation proposal, gives Integrys shareholders the opportunity to vote on a non-binding, advisory basis on the compensation that Integrys' named executive officers may be entitled to receive from Integrys that is based on or otherwise relates to the merger.

        The compensation that Integrys' named executive officers may be entitled to receive from Integrys that is based on or otherwise relates to the merger is summarized and included in "The Merger—Interests of Directors and Executive Officers in the Merger—Interests of Directors and Executive Officers of Integrys in the Merger—Golden Parachute Compensation" beginning on page 96. That summary includes all compensation and benefits that may be paid or become payable to Integrys' named executive officers by Integrys that is based on or otherwise relate to the merger.

        The Integrys Board encourages you to review carefully the named executive officer merger-related compensation information disclosed in this joint proxy statement/prospectus.

        The Integrys Board recommends that Integrys shareholders approve the following resolution:

        The affirmative vote of a majority of the shares of Integrys common stock represented (in person or by proxy) at the Integrys special meeting and entitled to vote on such proposal is required to approve the Merger-Related Compensation proposal. Because the vote on the Merger-Related Compensation proposal is advisory only, it will not be binding on either Integrys or Wisconsin Energy. Accordingly, if the merger agreement is adopted and the merger is completed, the compensation will be payable, subject only to the conditions applicable thereto, regardless of the outcome of the non-binding, advisory vote of Integrys shareholders.

        The Integrys Board recommends a vote FOR the Merger-Related Compensation proposal (Item 2).

Item 3.    The Integrys Meeting Adjournment Proposal

(Item 3 on Integrys Proxy Card)

        The Integrys special meeting may be adjourned to another time or place, if necessary or appropriate, to permit, among other things, further solicitation of proxies if necessary to obtain additional votes in favor of the Merger proposal.

        If, at the Integrys special meeting, the number of shares of Integrys common stock present or represented and voting in favor of the Merger proposal is insufficient to approve the Merger proposal, Integrys intends to move to adjourn the Integrys special meeting in order to enable the Integrys Board to solicit additional proxies for approval of the Merger proposal.

        In the Integrys Meeting Adjournment proposal, Integrys is asking its shareholders to authorize the holder of any proxy solicited by the Integrys Board to vote in favor of granting discretionary authority to the proxy holders, and each of them individually, to adjourn the Integrys special meeting to another time and place for the purpose of soliciting additional proxies. If the Integrys shareholders approve the Integrys Meeting Adjournment proposal, Integrys could adjourn the Integrys special meeting and any adjourned session of the Integrys special meeting and use the additional time to solicit additional proxies, including the solicitation of proxies from Integrys shareholders who have previously voted.

        If a quorum is not present at the Integrys special meeting, the approval of the Integrys Meeting Adjournment proposal requires the affirmative vote of the holders of a majority of the shares of Integrys common stock present, in person or by proxy, at the special meeting and entitled to vote thereon. If a quorum is present at the Integrys special meeting, approval of the Integrys Meeting Adjournment proposal requires that the votes cast in favor of such proposal exceed the votes cast against such proposal.

        The Integrys Board recommends a vote FOR the Integrys Meeting Adjournment proposal (Item 3).


Other Matters to Come Before the Meeting

        No other matters are intended to be brought before the meeting by Integrys, and Integrys does not know of any matters to be brought before the meeting by others. If, however, any other matters properly come before the meeting, the persons named in the proxy will vote the shares represented thereby in accordance with the judgment of management on any such matter.

UNAUDITED PRO FORMA CONDENSED COMBINED CONSOLIDATED
FINANCIAL INFORMATION

        The Unaudited Pro Forma Condensed Combined Consolidated Financial Statements (pro forma financial statements) have been derived from the historical consolidated financial statements of Wisconsin Energy and Integrys incorporated by reference into this joint proxy statement/prospectus. Upon completion of the transaction, the surviving entity is expected to be named WEC Energy Group, Inc.

        The Unaudited Pro Forma Condensed Combined Consolidated Statements of Income (pro forma statements of income) for the six months ended June 30, 2014 and the year ended December 31, 2013 give effect to the merger as if it were completed on January 1, 2013. The Unaudited Pro Forma Condensed Combined Consolidated Balance Sheet (pro forma balance sheet) as of June 30, 2014 gives effect to the merger as if it were completed on June 30, 2014.

        The historical consolidated financial information has been adjusted in the pro forma financial statements to give effect to pro forma events that are: (1) directly attributable to the merger; (2) factually supportable; and (3) with respect to the statements of income, expected to have a continuing impact on the combined results of Wisconsin Energy and Integrys. As such, the impact from the merger related expenses is not included in the accompanying pro forma statements of income. However, the impact of these expenses is reflected in the pro forma balance sheet as an increase to accounts payable and a decrease to retained earnings.

        The pro forma financial statements do not reflect any cost savings (or associated costs to achieve such savings) from operating efficiencies or synergies that could result from the merger. Further, the pro forma financial statements do not reflect the effect of any regulatory actions that may impact the pro forma financial statements when the merger is completed.

        Accounting standards generally accepted in the United States require that one party to the merger be identified as the acquirer. In accordance with these standards, the merger of Wisconsin Energy and Integrys will be accounted for as an acquisition of Integrys common shares by Wisconsin Energy and will follow the acquisition method of accounting for business combinations. The final purchase price will be determined on the basis of the fair value on the acquisition date of the common shares of Wisconsin Energy issued in the merger. The purchase price for the pro forma financial statements is based on the closing price of Wisconsin Energy common shares on the NYSE on September 18, 2014 of $44.01 and the exchange of Integrys' common shares for the right to receive 1.128 common shares of Wisconsin Energy, plus $18.58 in cash.

        Assumptions and estimates underlying the pro forma adjustments are described in the accompanying notes, which should be read in connection with the pro forma financial statements. Since the pro forma financial statements have been prepared based on preliminary estimates, the final amounts recorded at the date of the merger may differ materially from the information presented. These estimates are subject to change pending further review of the assets acquired and liabilities assumed and the final purchase price.

        The pro forma financial statements have been presented for illustrative purposes only and are not necessarily indicative of results of operations and financial position that would have been achieved had the pro forma events taken place on the dates indicated, or the future consolidated results of operations or financial position of the combined company.

        The following pro forma financial statements should be read in conjunction with:

NOTES TO THE UNAUDITED PRO FORMA CONDENSED

COMBINED CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Basis of Pro Forma Presentation

        The pro forma statements of income for the six months ended June 30, 2014 and the year ended December 31, 2013 give effect to the merger as if it were completed on January 1, 2013. The pro forma balance sheet as of June 30, 2014 gives effect to the merger as if it were completed on June 30, 2014.

        The pro forma financial statements have been derived from the historical consolidated financial statements of Wisconsin Energy and Integrys that are incorporated by reference into this joint proxy statement/prospectus. Assumptions and estimates underlying the pro forma adjustments are described in the accompanying notes, which should be read in conjunction with the pro forma financial statements. Since the pro forma financial statements have been prepared based upon preliminary estimates, the final amounts recorded at the date of the merger may differ materially from the information presented. These estimates are subject to change pending further review of the assets acquired and liabilities assumed.

        The merger is reflected in the pro forma financial statements as being accounted for as an acquisition of Integrys by Wisconsin Energy, based on the guidance provided by accounting standards for business combinations. Under the acquisition method, the total estimated purchase price is calculated as described in Note 2 to the pro forma financial statements. The assets acquired and the liabilities assumed have been measured at estimated fair value. For the purpose of measuring the estimated fair value of the assets acquired and liabilities assumed, Wisconsin Energy has applied the accounting guidance for fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. The fair value measurements utilize estimates based on key assumptions of the merger, including historical and current market data. The pro forma adjustments included herein are preliminary and will be revised at the time of the merger as additional information becomes available and as additional analyses are performed. The final purchase price allocation will be determined at the time that the merger is completed, and the final amounts recorded for the merger may differ materially from the information presented.

        Estimated transaction costs have been excluded from the pro forma statements of income as they reflect non-recurring charges directly related to the merger. However, the anticipated transaction costs are reflected in the pro forma balance sheet as an increase to accounts payable and a decrease to retained earnings.

        The pro forma financial statements do not reflect any cost savings (or associated costs to achieve such savings) from operating efficiencies that could result from the merger. Further, the pro forma financial statements do not reflect the effect of any regulatory actions that may impact the pro forma financial statements when the merger is completed.

        Integrys' regulated operations are comprised of the distribution of electricity and gas. These operations are subject to the retail ratesetting authority of various state regulatory commissions and the FERC, which includes provisions in place that provide revenues to recover costs of service, including a carrying charge on most net assets and liabilities. For the net assets and liabilities earning a carrying charge, the carrying values approximate fair values and pro forma adjustments are not required.

Note 2. Preliminary Purchase Price

        Wisconsin Energy will acquire all of the outstanding shares of Integrys common stock. Integrys shareholders will be entitled to receive for each share of Integrys common stock 1.128 common shares

                5,455.3  

Estimated consideration attributable to settlement of equity awards

        $ 56.3   $ 56.3

(a)
Includes 433.5 thousand shares of Integrys common stock held in rabbi trusts.

        The preliminary purchase price reflects the market value of Wisconsin Energy common shares to be issued in connection with the merger based on the closing price of Wisconsin Energy's common shares on September 18, 2014. The preliminary purchase price will fluctuate with the market price of Wisconsin Energy's common shares until it is reflected on an actual basis when the merger is completed. An increase or decrease of 10 percent in Wisconsin Energy's common share price from the $44.01 price used above would increase or decrease the purchase price by approximately $406 million.

Note 4. Pending Sale of Integrys' Retail Energy Business

        On July 30, 2014, Integrys' management announced that they entered into a definitive agreement to sell the retail energy business of Integrys Energy Services (IES) to a third party. The purchase price is $60 million plus an amount for adjusted working capital at the time of closing. As of May 31, 2014, IES had adjusted working capital of approximately $183 million. The IES retail energy business consists of mostly financial assets and liabilities and does not qualify as an asset held for sale under the applicable accounting guidance.

        Integrys' management expects the sale of the retail energy business of IES to be completed prior to the completion of the Wisconsin Energy acquisition of Integrys. The following table reflects key financial information of the retail energy business of IES that is included in Integrys' financial statements as of and for the six months ended June 30, 2014 and the year ended December 31, 2013:

COMBINED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Note 5. Investment in the American Transmission Company

        Equity method investments include the companies' combined 60 percent ownership of American Transmission Company (ATC). Prior to, or concurrent with consummation of the merger, we anticipate that we will substantively revise the governance and control provisions of ATC ownership such that this entity would not be consolidated under generally accepted accounting principles in the United States. We have initiated this process with ATC membership and FERC and believe this presentation most fairly represents the presentation that will exist when the merger closes.

COMPARISON OF SHAREHOLDER RIGHTS

        Both Wisconsin Energy and Integrys are incorporated in the State of Wisconsin. A shareholder of Integrys, whose rights as a shareholder are currently governed by the Wisconsin law, and the restated articles of incorporation and bylaws of Integrys, which we refer to as the Integrys charter and the Integrys bylaws, will, when the initial merger occurs, become a stockholder of Wisconsin Energy. The shareholder's rights will then be governed by the restated articles of incorporation and bylaws of Wisconsin Energy, which we refer to as the Wisconsin Energy charter and the Wisconsin Energy bylaws, but will continue to be governed by Wisconsin law.

        Certain differences between the rights of stockholders of Wisconsin Energy and shareholders of Integrys, and certain other important provisions of Wisconsin law affecting shareholder rights, are described below. Because this is a summary, it may not include all of the information that is important to you. You are encouraged to review the articles of incorporation and bylaws of each company, and the applicable provisions of Wisconsin law, because these are the legal documents that determine your rights. Copies of each company's articles of incorporation and bylaws have been filed with the SEC. Please see "Where You Can Find More Information" on page 174.


Authorized Capital Stock

        The Wisconsin Energy charter authorizes the issuance of 325,000,000 shares of Wisconsin Energy common stock, par value of $0.01, of which 225,517,341 shares were issued and outstanding as of the Wisconsin Energy record date, and the issuance of 15,000,000 shares of Wisconsin Energy preferred stock, none of which were issued and outstanding as of the Wisconsin Energy record date. The Wisconsin Energy Board is authorized to divide the preferred stock into series, to issue shares of any series and, within the limitations set forth in the Wisconsin Energy charter or prescribed by law, to determine the relative rights and preferences of the shares of any series.

        The Integrys charter authorizes the issuance of 200,000,000 shares of Integrys common stock, par value $1.00, of which 79,963,091 shares were issued and outstanding as of the Integrys record date. The Integrys charter does not authorize the issuance of preferred stock.


Voting Rights

        The Wisconsin Energy charter and the Integrys bylaws each provide that each share of their respective common stock is entitled to one vote on each matter submitted to a vote of shareholders. The voting rights, if any, of holders of Wisconsin Energy preferred stock are determined by the Wisconsin Energy Board at the time the preferred stock is issued, except under the limited circumstances when Wisconsin law may require voting rights with respect to the preferred stock of Wisconsin Energy. Neither the Integrys charter nor the Wisconsin Energy charter provide for cumulative voting in the election of directors. Under Wisconsin law, shareholders do not have the right to cumulate their votes for directors unless a company's articles of incorporation provide for cumulative voting. Under the Integrys bylaws, shares of Integrys common stock held by another corporation, if a sufficient number of such shares are held directly or indirectly by Integrys to elect a majority of the directors of such other corporation, are not entitled to vote but shares held in a fiduciary capacity may be voted.


Shareholder Quorum and Voting Requirements

        Under the Wisconsin Energy bylaws, except as otherwise provided in the Wisconsin Energy charter or in the Wisconsin Business Corporation Law, a majority of the votes entitled to be cast by shares entitled to vote as a separate voting group on a matter, represented in person or by proxy, shall constitute a quorum of that voting group for action on that matter at a meeting of stockholders. If a quorum exists, action on a matter, other than the election of directors, by a voting group is approved if the votes cast within the voting group favoring the action exceed the votes cast opposing the action

166


Table of Contents

unless a greater number of affirmative votes is required by the Wisconsin Business Corporation Law, the Wisconsin Energy charter, or another provision of the Wisconsin Energy bylaws. The Integrys bylaws set forth substantially similar shareholder quorum and voting requirements as described in this paragraph.


Bylaw Provisions Fixing Greater Voting Requirements

        The Wisconsin Energy charter provides that the bylaws may require a greater stockholder vote than would otherwise be required by law or by the charter for: (i) removal of a director from office; or (ii) amending provisions of the bylaws relating to or in connection with taking action by the unanimous consent of stockholders without a meeting; the number, term, qualification, classification and election of directors; the removal of a director from office; notice for Board of Directors' meetings; indemnification of officers, directors and other persons by the corporation; or Bylaw amendments. The Integrys charter provides that the Integrys bylaws may provide for a greater or lower quorum requirement or a greater voting requirement for shareholders or voting groups of shareholders than is provided by the Wisconsin Business Corporation Law.


Extraordinary Transactions

        Wisconsin law provides that the approval by holders of a majority of all votes entitled to be cast is required for a Wisconsin corporation to effect certain extraordinary transactions, including the sale of all or substantially all of its assets, or a merger, share exchange or dissolution, unless a greater vote or a vote by voting groups is otherwise required by law or by the corporation's articles of incorporation or bylaws. Approval of extraordinary transactions by shareholders of Integrys or stockholders of Wisconsin Energy requires only the majority vote described in this paragraph.


Board of Directors

        The Wisconsin Energy charter provide that the number of directors will be fixed from time to time in the manner provided in the Wisconsin Energy bylaws. The Wisconsin Energy bylaws provide that the number of directors will be fixed from time to time by the Wisconsin Energy Board, but will not be less than three. The terms of Wisconsin Energy's directors expire each year. The Wisconsin Energy Board currently consists of nine directors.

        In a non-contested election, Wisconsin Energy directors are elected by a majority of the votes cast by the Wisconsin Energy shares entitled to vote in the election at a stockholders meeting at which a quorum is present. A "majority of the votes cast" means that the number of shares voted "for" a director's election exceeds 50 percent of the number of votes cast with respect to that director's election. Votes cast will include votes "for" and "against" that director's election in each case and direction to withhold authority in each case, and exclude abstentions and broker non-votes with respect to that director's election. In a contested election, directors are elected by a plurality of the votes cast by the Wisconsin Energy shares entitled to vote in the election at a stockholders meeting at which a quorum is present. Under the Wisconsin Energy bylaws, an election is considered contested if, as of the last day on which a stockholder may propose the nomination of a director for election in such election under the Wisconsin Energy bylaws, there are more nominees than positions on the board of directors to be filled by election at the meeting.

        The Integrys charter provides that the general powers, number and classification of its directors will be as set forth in the Integrys bylaws. The Integrys charter specifies that those bylaw provisions may be amended only by the affirmative vote of Integrys shareholders holding at least three-fourths of the voting power of the then outstanding shares of Integrys common stock generally possessing voting rights in the election of directors, or by the affirmative vote of at least two-thirds of directors plus one director (i.e., currently by 8 of the 11 directors). The Integrys bylaws provide that Integrys will have

167


Table of Contents

eleven directors with a term of one year each. Each director holds office for a term expiring at the following annual meeting of shareholders and until the director's successor is elected and qualified. The Integrys bylaws also provide that no director shall be eligible for election after attaining the age of 72 years.

        Integrys directors are elected if the number of votes cast favoring that individual's election exceeds the number of votes cast opposing that individual's election at any meeting for the election of directors at which a quorum of shareholders is present and the election is uncontested. If the Integrys Board determines that the number of persons properly nominated to serve as directors of Integrys exceeds the number of directors to be elected, resulting in a contested election, then directors will be elected by a plurality of the votes cast by the Integrys shares entitled to vote in the election of directors at a meeting at which a quorum of shareholders is present.

        The Wisconsin Energy bylaws provide that directors may be removed for cause (which is not defined by the bylaws) by a majority of the aggregate number of votes that holders of the then outstanding Wisconsin Energy common stock and preferred stock are entitled to cast, voting together as a single class, in the election of directors. Removal without cause requires 80 percent of the aggregate number of the votes of such holders.

        The Integrys charter provides that any director may be removed from office, but only for cause, by the affirmative vote of shareholders holding at least a majority of the voting power of the then outstanding shares generally possessing voting rights in the election of directors, considered for this purpose as one class. "Cause" will be construed to exist only if the director whose removal is proposed has been convicted of a felony by a court of competent jurisdiction and such conviction is no longer subject to direct appeal or has been adjudged liable for negligence or misconduct in the performance of his or her duties to Integrys in a matter which has a material adverse effect on the business of Integrys and that adjudication is no longer subject to direct appeal.

        However, if the Integrys Board has recommended removal of a director by a resolution adopted by at least two-thirds of directors plus one director (i.e., currently by 8 of the 11 directors), then shareholders may remove the director from office without cause by the affirmative vote of shareholders holding at least a majority of the voting power of the then outstanding Integrys shares generally possessing voting rights in the election of directors.

        The Integrys charter provides that any vacancies on the Integrys Board will be filled by appointment made by a majority of the remaining directors, even if less than a quorum, or by a sole remaining director. The Wisconsin Energy bylaws provide that any vacancies on the Wisconsin Energy Board may be filled by stockholders or by a majority of the remaining directors, even if less than a quorum. The Wisconsin Energy bylaws provide that any new director elected to fill a vacancy will serve until the next annual meeting of stockholders. The Integrys charter provides any new director elected to fill a vacancy will serve for the remainder of the then present term of directors in which the vacancy is being filled.


Shareholder Nominations and Proposals

        Under the Wisconsin Energy bylaws, a stockholder entitled to vote at a meeting may nominate a person for election as director or propose any actions to be taken at a meeting only if written notice of any stockholder nomination and/or proposal to be considered for a vote at an annual meeting of stockholders is delivered personally or mailed by Certified Mail-Return Receipt Requested at least 70 days and not more than 100 days before the scheduled date of such meeting to the corporate secretary of Wisconsin Energy at the principal business office of the corporation. A stockholder entitled

168


Table of Contents

to vote at a special meeting may nominate a person for election as director and/or propose action to be taken at a meeting only if written notice of any stockholder nomination and/or proposal to be considered for a vote at a special meeting is delivered personally or mailed by Certified Mail-Return Receipt Requested to the corporate secretary of Wisconsin Energy at its principal business office so that it is received in a reasonable period of time before such special meeting and only if such nomination or proposal is within the purposes described in the notice to stockholders of the special meeting.

        Under the Integrys bylaws, Integrys shareholders must give timely notice in writing to the corporate secretary of Integrys at its principal offices of nominations or other proposals of business to be brought before an annual meeting of Integrys not earlier than the close of business on the 120th day and not later than the close of business on the 90th day prior to the first anniversary of the preceding year's annual meeting. If the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, notice by the shareholder to be timely must be so delivered not earlier than the close of business on the 100th day prior to the date of such annual meeting and not later than the close of business on the later of (A) the 75th day prior to the date of such annual meeting or (B) the 10th day following the day on which public announcement of the date of such annual meeting is first made by Integrys. In the case of special meetings, nominations of persons for election to the Integrys Board may be made at a special meeting at which directors are to be elected pursuant to such notice of meeting (i) by or at the direction of the Integrys Board or (ii) by any Integrys shareholder who (A) is a shareholder of record at the time of giving of such notice of meeting, (B) is entitled to vote at the meeting and (C) complies with certain required notice procedures. Any shareholder desiring to nominate persons for election to the Integrys Board at such a special meeting must send written notice to the corporate secretary of Integrys at its principal office not earlier than ninety days prior to such special meeting and not later than the close of business on the later of (x) the 60th day prior to such special meeting and (y) the 10th day following the day on which public announcement is first made of the date of such special meeting and of the nominees proposed by the Integrys Board to be elected at such meeting.


Defensive Provisions

        Wisconsin law provides that, unless a corporation's articles of incorporation provide otherwise, the voting power of shares of a "resident domestic corporation" such as Wisconsin Energy or Integrys held by any person (including two or more persons acting as a group) in excess of 20 percent of the voting power in the election of directors is limited (in voting on any matter) to 10 percent of the full voting power of those shares. This restriction does not apply to shares acquired directly from the resident domestic corporation, or in certain specified transactions, or incident to a transaction in which the corporation's shareholders have approved restoration of the full voting power of the otherwise restricted shares.

        Under its charter, Wisconsin Energy has opted out of this control share acquisition restriction. Integrys has not opted out of such restriction.

        Wisconsin law restricts the ability of certain publicly held corporations, such as Wisconsin Energy and Integrys, to repurchase voting shares at above market value from certain large shareholders, absent approval from the shareholders as a whole, unless an identical or better offer to purchase is made to all owners of voting shares and securities which may be converted into voting shares. These provisions apply during a takeover offer to purchases of more than 5 percent of the corporation's shares from a person or group that holds more than 3 percent of the corporation's voting shares and has held the shares for less than two years.

169


Table of Contents

        Wisconsin law also provides that shareholder approval is required for the corporation during a takeover offer to sell or option assets of the corporation which amount to at least 10 percent of the market value of the corporation, unless the corporation has at least three independent directors (directors who are not officers or employees) and a majority of the independent directors vote not to have this provision apply to the corporation.

        In addition, the Wisconsin Energy charter prohibits Wisconsin Energy from purchasing shares of Wisconsin Energy common stock from a holder of 5 percent of such shares at a market premium, unless the holder has owned the shares for at least two years, the purchase was approved by a majority of the combined voting power of its stockholders, or the purchase is pursuant to a tender offer to all holders on the same terms. With respect to this restriction, the Wisconsin Energy charter requires an affirmative vote by 80 percent of the aggregate number of votes that holders of Wisconsin Energy common stock and preferred stock are entitled to cast on a charter amendment (and the same percentage of any separate class vote of holders of shares of such a class or series so entitled to vote under the Wisconsin Energy charter or Wisconsin law as a class) if that amendment would have the effect of amending the restriction.

        Wisconsin law provides that in addition to any approval otherwise required, certain mergers, share exchanges or sales, leases, exchanges or other dispositions involving a resident domestic corporation, such as Integrys or Wisconsin Energy, and any significant shareholder are subject to a super-majority vote of shareholders unless certain fair price standards have been met. For this purpose a significant shareholder is defined as either a 10 percent shareholder or an affiliate of the resident domestic corporation who was a 10 percent shareholder at any time within the preceding two years. The super-majority vote that is required by the statute consists of:

        However, a supermajority vote is not required if the following "fair price" standards are satisfied:

        Neither Wisconsin Energy nor Integrys has opted out of the restrictions above. The Wisconsin Energy charter further requires an affirmative vote by 80 percent of the aggregate number of votes that holders of Wisconsin Energy common stock and preferred stock are entitled to cast on a charter amendment (and the same percentage of any separate class vote of holders of shares of such a class or series so entitled to vote under the Wisconsin Energy charter or Wisconsin law as a class) if that amendment would have the effect of opting out of the fair price provisions.

        Wisconsin law restricts resident domestic corporations, such as Integrys and Wisconsin Energy, from engaging in specified business combinations involving an "interested stockholder" or an affiliate

170


Table of Contents

or associate of an interested stockholder. For this purpose an "interested stockholder" is a stockholder who beneficially owns at least 10 percent of the voting power of the outstanding stock of the resident domestic corporation, or is an affiliate or associate of the resident domestic corporation and beneficially owned at least 10 percent of the voting power of the then outstanding stock within the preceding three years. The specified business combinations include:

        For a period of three years following the date that the interested shareholder becomes an interested stockholder, the resident domestic corporation is prohibited from engaging in any of the specified transactions with an interested stockholder unless the specified transaction or the purchase of stock by the interested stockholder is approved by the board of directors of the resident domestic corporation before the date such person became an interested stockholder, which we refer to as the share acquisition date. Following the three year period, a specified transaction is permitted only if:

        Wisconsin corporations may not opt out of the restrictions above.


Amendments to Articles of Incorporation

        Wisconsin law generally provides that amendments to the articles of incorporation may be approved by a majority of the votes cast by each class or series of shares entitled to vote separately on the amendment, if a quorum exists, unless a greater proportion is required by statute, by the articles of incorporation or by the bylaws.

        The Wisconsin Energy charter generally requires an affirmative vote by at least a majority of the aggregate number of votes that holders of Wisconsin Energy common stock and preferred stock are entitled to cast on a charter amendment (and the same percentage of any separate class vote of holders of shares of such a class or series so entitled to vote under the Wisconsin Energy charter or Wisconsin law as a class). However, amendments to certain sections, including those relating to the preferred stock provisions, restrictions on greenmail specific to Wisconsin Energy, amendments to the charter itself and, as noted above, any provision that would have the effect of rendering inapplicable to

171


Table of Contents

Wisconsin Energy the fair price provision of the Wisconsin Business Corporation Law, require the affirmative vote of 80 percent of the votes entitled to be cast on such amendment.

        The Integrys charter provides that amendments relating to certain sections, including those relating to the general powers, number, classification, removal and appointment of directors, require the affirmative vote of the shareholders holding at least three-fourths of the voting power of all outstanding stock generally possessing voting rights in the election of directors, considered for this purpose as a single class.


Amendments to Bylaws

        Under Wisconsin law, the Wisconsin Energy bylaws and Integrys bylaws, the bylaws generally may be amended or repealed by either the board of directors or by a majority of the votes cast at a shareholders meeting at which a quorum is present. Under the Integrys bylaws, the Integrys Board has no power to amend any bylaw or reinstate any bylaw repealed by shareholders unless shareholders have conferred such authority upon the Integrys Board. Under the Wisconsin Energy bylaws, no bylaw adopted by stockholders may be amended, repealed or readopted by the Wisconsin Energy Board if such bylaw provides that it may not be amended, repealed or readopted by the Wisconsin Energy Board, and a bylaw adopted or amended by stockholders that fixes a greater or lower quorum requirement or a greater voting requirement for the Wisconsin Energy Board than otherwise is provided in the Wisconsin Business Corporation Law may not be amended or repealed by the Wisconsin Energy Board unless the bylaw expressly provides that it may be amended or repealed by a specified vote of the Wisconsin Energy Board.

        Provisions of the Integrys bylaws relating to the general powers, number and classification of directors, may generally be amended only by the affirmative vote of shareholders holding at least three-fourths of the voting power of the outstanding stock generally possessing voting rights in the election of directors. Provisions of the Integrys bylaws relating to the indemnification of officers and directors may generally be amended only by the affirmative vote of a majority of the shareholders so entitled to vote, except when such amendment would conform with certain changes in Wisconsin law with respect to such indemnification or when, in its sole judgment and discretion, the Integrys Board determines such amendment would not materially adversely affect the rights and protections of Integrys shareholders.

        Amendments to certain provisions of the Wisconsin Energy bylaws require the affirmative vote of at least 80 percent of the aggregate number of votes which the holders of the then outstanding shares of Wisconsin Energy common stock and preferred stock, voting together as a class, are entitled to cast in an election of directors. Those provisions include:


Shareholder Rights Plans

        Neither Wisconsin Energy nor Integrys has a shareholder rights plan.

        WHEREAS, within 30 days after the date of this Agreement, Parent will cause to be formed two direct, wholly owned Subsidiaries of Parent as Wisconsin corporations (referred to as "Merger Sub" and "Subsequent Merger Sub" and, collectively, the "Merger Subsidiaries"), and cause the Merger Subsidiaries to execute a joinder in the form attached hereto as Exhibit A to become parties to this Agreement (a "Joinder");

        WHEREAS the parties hereto intend that, upon the terms and subject to the conditions set forth in this Agreement, (a) at the Effective Time, Merger Sub will merge with and into the Company, with the Company surviving the merger as the surviving corporation (the "Initial Merger") and (b) immediately after the Effective Time and without further approval, authorization or direction from or by any of the parties hereto, through the binding commitment evidenced by Section 1.07 and as part of an integrated plan with the Initial Merger, the Initial Surviving Corporation will merge with and into Subsequent Merger Sub (the "Subsequent Merger" and, together with the Initial Merger, the "Mergers"), with Subsequent Merger Sub surviving the Subsequent Merger as the Surviving Corporation;

        WHEREAS the Board of Directors of the Company (the "Company Board") and the Board of Directors of Parent (the "Parent Board"), by resolution, have each approved this Agreement, and the Board of Directors of Merger Sub and the Board of Directors of Subsequent Merger Sub, by resolution, will have each approved this Agreement immediately prior to executing a Joinder;

        WHEREAS the Company Board and the Parent Board have each determined that the Initial Merger, upon the terms and subject to the conditions set forth in this Agreement, is in the best interests of the Company and Parent, as applicable, and their respective shareholders, and the Board of Directors of Merger Sub will have determined, immediately prior to executing a Joinder, that the Initial Merger, upon the terms and subject to the conditions set forth in this Agreement, is in the best interest of Merger Sub and its shareholder;

        WHEREAS the Parent Board has determined that the Subsequent Merger, upon the terms and subject to the conditions set forth in this Agreement, is in the best interests of Parent and its shareholders, and the Board of Directors of Subsequent Merger Sub will have determined, immediately prior to executing a Joinder, that the Subsequent Merger, upon the terms and subject to the conditions set forth in this Agreement, is in the best interest of Subsequent Merger Sub and its shareholder;

        WHEREAS the Company Board has resolved, and the Board of Directors of Merger Sub and the Board of Directors of Subsequent Merger Sub, immediately prior to executing a Joinder will have resolved, to recommend the approval of this Agreement by their respective shareholders;

        WHEREAS the Parent Board has resolved to recommend the approval by its shareholders of the issuance of shares of Parent Common Stock and the amendment to the Parent Articles contemplated by this Agreement;

        WHEREAS for U.S. Federal income tax purposes the Initial Merger and the Subsequent Merger are intended to qualify for the Intended Tax Treatment; and

        WHEREAS the Company and Parent and, upon execution of a Joinder, Merger Sub and Subsequent Merger Sub, each desire to make certain representations, warranties, covenants and agreements in connection with the Mergers and also to prescribe various conditions to the Mergers.

        Parent represents and warrants to the Company that the statements contained in this ARTICLE III are true and correct, except (i) as set forth in the Parent Reporting Documents publicly available and filed with or furnished to the SEC prior to the date of this Agreement (the "Filed Parent Reporting Documents") (excluding any disclosures in the Filed Parent Reporting Documents under the heading "Risk Factors" and any other disclosures that are predictive or forward-looking in nature) or (ii) as set forth in the disclosure letter delivered by Parent to the Company prior to the execution and delivery by Parent of this Agreement (the "Parent Disclosure Letter").


        SECTION 3.01
    Organization, Standing and Power.     Each of Parent and each of Parent's Subsidiaries (the "Parent Subsidiaries") is duly organized, validly existing and in good standing under the laws of the jurisdiction in which it is organized (in the case of good standing, to the extent such jurisdiction recognizes such concept), except, in the case of the Parent Subsidiaries (other than the Merger Subsidiaries), where the failure to be so organized, existing or in good standing, individually or in the aggregate, has not had and would not reasonably be expected to have a Parent Material Adverse Effect. Each of Parent and the Parent Subsidiaries has all requisite power and authority and possesses all governmental franchises, licenses, permits, authorizations, variances, exemptions, orders, registrations, clearances and approvals (collectively, "Permits") necessary to enable it to own, operate, lease or otherwise hold its properties and assets and to conduct its businesses as presently conducted (the "Parent Permits"), except where the failure to have such power or authority or to possess Parent Permits, individually or in the aggregate, has not had and would not reasonably be expected to have a Parent Material Adverse Effect. Each of Parent and the Parent Subsidiaries is duly qualified or licensed to do business in each jurisdiction where the nature of its business or the ownership, operation or leasing of its properties make such qualification necessary, other than in such jurisdictions where the failure to be so qualified or licensed, individually or in the aggregate, has not had and would not reasonably be expected to have a Parent Material Adverse Effect. Parent has delivered or made available to the Company, prior to execution of this Agreement, true and complete copies of the restated articles of incorporation of Parent in effect as of the date of this Agreement (the "Parent Articles") and the by-laws of Parent in effect as of the date of this Agreement (the "Parent By-laws").


        SECTION 3.02
    Parent Subsidiaries.     (a) All the outstanding shares of capital stock or voting securities of, or other equity interests in, each Parent Subsidiary have been validly issued and are fully paid and nonassessable and are owned by Parent, by another Parent Subsidiary or by Parent and another Parent Subsidiary, free and clear of all pledges, liens, charges, mortgages, encumbrances and security interests of any kind or nature whatsoever (collectively, "Liens"), and free of any other restriction (including any restriction on the right to vote, sell or otherwise dispose of such capital stock, voting securities or other equity interests), except for restrictions imposed by applicable securities laws. Section 3.02(a) of the Parent Disclosure Letter sets forth, as of the date of this Agreement, a true and complete list of the Parent Subsidiaries.

        (b)   Except for the capital stock and voting securities of, and other equity interests in, the Parent Subsidiaries, neither Parent nor any Parent Subsidiary owns, directly or indirectly, any capital stock or voting securities of, or other equity or ownership interests in, or any interest convertible into or exchangeable or exercisable for, any capital stock or voting securities of, or other equity interests in, any firm, corporation, partnership, company, limited liability company, trust, joint venture, association or other entity.

pending, or to the Knowledge of the Company, threatened, judicial or administrative proceedings to revoke a Company Subsidiary's market-based rate authorization. To the Knowledge of the Company, there are no facts that are reasonably likely to cause any of the Company Subsidiaries that sell electricity at wholesale to lose its market-based rate authorization, if applicable, other than where such loss would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect.

        (c)   All filings (other than immaterial filings) required to be made by the Company or any of the Company Subsidiaries since January 1, 2012, with the FERC under the Power Act, the DOE and any State Utilities Commission, as the case may be, have been made, including all forms, statements, reports, agreements and all documents, exhibits, amendments and supplements appertaining thereto, including all rates, tariffs and related documents, and all such filings complied, as of their respective dates, with all applicable requirements of applicable statutes and the rules and regulations promulgated thereunder, except for filings the failure of which to make or the failure of which to make in compliance with all applicable requirements of applicable statutes and the rules and regulations promulgated thereunder, would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect.

        (d)   Since January 1, 2012, neither the Company nor any of the Company Subsidiaries has received any written notice or, to the Company's Knowledge, other communication from the NERC regarding any actual or possible material violation of, or material failure to comply with, any Law.

        (e)   None of the Company or the Company Subsidiaries currently owns or operates, in whole or in part, any nuclear generating facilities. With respect to the Company's former interest in the Kewaunee Nuclear Power Plant, the Company is in compliance with all requirements of the agreement governing the sale of such plant, except where such non-compliance has not and would not be reasonably expected to have, individually or in the aggregate, a Company Material Adverse Effect. There are no contingent liabilities for the Company associated with the Company's prior ownership or operation of the Kewaunee Nuclear Power Plant, except such contingent liabilities that would not be expected to have, individually or in the aggregate, a Company Material Adverse Effect.

    Trading.     IES has established risk parameters, limits and guidelines (the "Company Trading Guidelines") in compliance with the risk management policy approved by the Company Board, the board of directors of IES and the Integrys Energy Risk Oversight Committee ("IROC") to restrict the level of risk that IES and its Subsidiaries are authorized to take with respect to, among other things, the net position resulting from all physical commodity transactions, exchange-traded futures and options transactions, and over-the-counter derivatives transactions (the "Net Company Position") and monitors compliance by IES and its Subsidiaries with such Company Trading Guidelines. The Company has provided a copy of the Company Trading Guidelines to Parent prior to the date of this Agreement. At no time between March 31, 2014 and the date of this Agreement, (i) has the Net Company Position not been within the risk parameters in all material respects that are set forth in the Company Trading Guidelines, other than as approved by IROC in accordance with the procedures contained in the Company Trading Guidelines and (ii) has the exposure of IES and its Subsidiaries with respect to the Net Company Position resulting from all such transactions been material to Company and the Company Subsidiaries taken as a whole. From March 31, 2014 to the date of this Agreement, IES and its Subsidiaries have not, in accordance with generally recognized mark to market accounting policies, experienced an aggregate net loss in their trading and related operations that would be material to Company and the Company Subsidiaries taken as a whole. None of the Company or any of the Company Subsidiaries (other than (x) IES and (y) any Company Subsidiary that is a regulated public utility with franchise service obligations for retail electricity or gas supply in the State of Wisconsin, Illinois, Michigan or Minnesota) engage in any physical commodity transactions, exchange traded futures and options transactions, and over-the-counter derivatives transactions.

    No Solicitation by Parent; Parent Board Recommendation.     (a) Parent shall not, and shall not authorize or permit any of its Affiliates to, and shall instruct, and shall cause its Affiliates to instruct, its and their respective directors, officers or employees or any of their respective investment bankers, accountants, attorneys or other advisors, agents or representatives (collectively, "Representatives") not to, (i) directly or indirectly solicit, initiate, knowingly encourage, induce or knowingly facilitate any Parent Takeover Proposal or any inquiry or proposal that could reasonably be expected to lead to a Parent Takeover Proposal, or (ii) directly or indirectly participate in any discussions or negotiations with any Person (other than Parent's Representatives) regarding, or furnish to any Person any information with respect to, or cooperate in any way with any Person (whether or not such Person is making a Parent Takeover Proposal) with respect to any Parent Takeover Proposal or any inquiry or proposal that may reasonably be expected to lead to a Parent Takeover Proposal. Parent shall, and shall cause its Affiliates and its and their respective Representatives to, immediately cease and cause to be terminated all existing discussions or negotiations with any Person conducted heretofore with respect to any Parent Takeover Proposal, or any inquiry or proposal that may reasonably be expected to lead to a Parent Takeover Proposal, request the prompt return or destruction of all confidential information previously furnished and immediately terminate all physical and electronic dataroom access previously granted to any such Person or its Representatives.

Parent Subsidiaries to the Person making such Parent Takeover Proposal (and its Representatives) (provided that all such information has previously been provided to the Company or is provided to the Company prior to or substantially concurrent with the time it is provided to such Person) pursuant to a customary confidentiality agreement not less restrictive of such Person than the Confidentiality Agreement, and (B) participate in discussions regarding the terms of such Parent Takeover Proposal and the negotiation of such terms with, and only with, the Person making such Parent Takeover Proposal (and such Person's Representatives). Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in this Section 5.02(a) by any Representative of Parent or any of its Affiliates shall constitute a breach of this Section 5.02(a) by Parent.

        (b)   Except as set forth below, neither the Parent Board nor any committee thereof shall (i) (A) withdraw (or modify in any manner adverse to the Company), or propose publicly to withdraw (or modify in any manner adverse to the Company), the approval or recommendation by the Parent Board or any such committee thereof with respect to this Agreement, the Mergers, or the Share Issuance or (B) approve or recommend, or propose publicly to approve or recommend, any Parent Takeover Proposal (any action in this clause (i) being referred to as a "Parent Adverse Recommendation Change") or (ii) approve or recommend, or propose publicly to approve or recommend, or allow Parent or any of its Affiliates to execute or enter into, any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement, option agreement, joint venture agreement, alliance agreement, partnership agreement or other agreement or arrangement (other than a confidentiality agreement referred to in Section 5.02(a)) (an "Acquisition Agreement") constituting or relating to, or that is intended to or would reasonably be expected to lead to, any Parent Takeover Proposal, or requiring, or reasonably expected to cause, Parent or the Merger Subsidiaries to abandon, terminate, delay or fail to consummate, or that would otherwise impede, interfere with or be inconsistent with, the Mergers or any of the other transactions contemplated by this Agreement, or requiring, or reasonably expected to cause, Parent or the Merger Subsidiaries to fail to comply with this Agreement.

        (c)   Notwithstanding the foregoing, at any time prior to obtaining the Parent Shareholder Approval, the Parent Board may terminate this Agreement pursuant to Section 8.01(f)(ii); provided, however, that the Parent Board may not terminate this Agreement pursuant to Section 8.01(f)(ii) unless (i) the Parent Board has provided prior written notice to the Company (a "Parent Notice") that it is prepared to terminate this Agreement pursuant to Section 8.01(f)(ii) in response to a Superior Parent Proposal, which notice shall attach the most current draft of any written agreement relating to the transaction that constitutes such Superior Parent Proposal, (ii) the Company does not, within four Business Days after the receipt of such Parent Notice (it being understood and agreed that any amendment to the financial terms or any other material term of a Superior Parent Proposal shall require a new Parent Notice and a new four Business Day period), propose changes to this Agreement that would, in the reasonable good faith judgment of the Parent Board (after consultation with a financial advisor of nationally recognized reputation and outside legal counsel), cause the offer previously constituting a Superior Parent Proposal to no longer constitute a Superior Parent Proposal, and (iii) at the end of such four Business Day period and taking into account any changes to the terms of this Agreement proposed by the Company, the Parent Board determines in good faith (after consultation with a financial advisor of nationally recognized reputation and outside legal counsel) that the failure to terminate this Agreement pursuant to Section 8.01(f)(ii) as a result of such Superior Parent Proposal would be inconsistent with its fiduciary duties under applicable Law. Parent agrees that, during the four Business Day period prior to terminating this Agreement pursuant to Section 8.01(f)(ii) in response to a Superior Parent Proposal, if requested by the Company, Parent and its Representatives shall negotiate in good faith with the Company and its Representatives regarding any revisions to the terms of the transaction contemplated by this Agreement proposed by the Company. In determining whether to terminate this Agreement pursuant to Section 8.01(f)(ii), the Parent Board shall take into account all written or oral information, opinions or analyses submitted by

or on behalf of the Company, and any changes to the terms of this Agreement proposed by the Company in response to such a Parent Notice.

        (d)   Notwithstanding the foregoing, at any time prior to obtaining the Parent Shareholder Approval, the Parent Board may effect a Parent Adverse Recommendation Change (x) as a result of the occurrence of a Parent Intervening Event or (y) in response to a Superior Parent Proposal, in each case if the Parent Board determines in good faith (after consultation with a financial advisor of nationally recognized reputation and outside legal counsel and after taking into account any changes to the terms of this Agreement proposed by the Company during the four Business Day period referred to in clause (ii) below) that the failure to effect a Parent Adverse Recommendation Change as a result of the occurrence of such Parent Intervening Event or in response to such Superior Parent Proposal, as the case may be, would be inconsistent with its fiduciary duties to the shareholders of Parent under applicable Law; provided, however, that the Parent Board may not effect a Parent Adverse Recommendation Change under this clause (d) unless (i) the Parent Board has provided four Business Days prior written notice to the Company that it is prepared to effect a Parent Adverse Recommendation Change in response to a Parent Intervening Event or a Superior Parent Proposal, which notice shall, in the case of a Parent Adverse Recommendation Change in response to a Superior Parent Proposal, include summaries of the material facts, circumstances and other information that the Parent Board considered in connection with the making of any such determination and (ii) during such four Business Day period, if requested by the Company, the Parent Board negotiates in good faith with the Company and its Representatives regarding any revisions to the terms of the transaction contemplated by this Agreement proposed by the Company.

        (e)   In addition to the obligations of Parent set forth in paragraphs (a) and (b) of this Section 5.02, Parent shall promptly advise (and in any event within 48 hours) the Company orally and in writing of any Parent Takeover Proposal, the material terms and conditions of any such Parent Takeover Proposal (including any changes thereto) and the identity of the Person making any such Parent Takeover Proposal. Parent shall keep the Company informed in all material respects on a current basis of the terms and status (including any change to the terms thereof) of any Parent Takeover Proposal.

        (f)    Nothing contained in this Section 5.02 shall prohibit Parent from (i) complying with Rule 14d-9 and Rule 14e-2 promulgated under the Exchange Act or (ii) making any disclosure to the shareholders of Parent if, in the good faith judgment of the Parent Board (after consultation with outside legal counsel) failure to so disclose would be inconsistent with its obligations under applicable Law; provided, however, that in no event shall Parent or the Parent Board or any committee thereof take, or agree or resolve to take, any action prohibited by Section 5.02.

Stat. § 196.807, to the extent applicable, with at least the same wages and substantially equivalent fringe benefits and other terms and conditions of employment that such Company Employees received immediately prior to the Effective Time, in each case for a period of thirty months following the Effective Time, unless different terms and conditions of employment are collectively bargained.

        (d)   At the Effective Time, Parent shall, or shall cause the Surviving Corporation or its Subsidiaries to, assume and honor in accordance with their terms all of the Company's and its Subsidiaries' employment, severance, retention, termination and change in control plans, policies, programs, agreements and arrangements (including any change in control severance agreement or other arrangement between the Company and any Company Employee) maintained by the Company or any Company Subsidiary, in each case, as in effect at the Effective Time, including with respect to any payments, benefits or rights arising as a result of the transactions contemplated by this Agreement (either alone or in combination with any other event).

        (e)   With respect to all employee benefit plans of Parent, the Surviving Corporation or any of their Subsidiaries, including any "employee benefit plan" (as defined in Section 3(3) of ERISA) (including any vacation, paid time-off and severance plans), each Company Employee's service with the Company or any Company Subsidiary (as well as service with any predecessor employer of the Company or any such Company Subsidiary, to the extent service with the predecessor employer was recognized by the Company or such Company Subsidiary) shall be treated as service with Parent, the Surviving Corporation or any of their Subsidiaries for all purposes (other than benefit accrual under any defined benefit plan or frozen benefit plan or vesting under any equity incentive plan), including determining eligibility to participate, level of benefits, vesting and benefit accruals, except to the extent that such service was not recognized under the corresponding Company Benefit Plan immediately prior to the Effective Time, such recognition would result in any duplication of benefits for the same period of service or for purposes of qualifying for subsidized early retirement benefits.

        (c)   No party shall have any liability or shall have any remedy in respect of any misrepresentation or untrue statement unless, and solely to the extent that, a claim lies for breach of a representation or warranty included in this Agreement. This Section 9.08(c) shall not apply to the extent mandatory applicable Law prohibits the exclusion of liability for fraudulent misrepresentation.


        SECTION 9.09    GOVERNING LAW.     THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF WISCONSIN, REGARDLESS OF THE LAWS THAT MIGHT OTHERWISE GOVERN UNDER ANY APPLICABLE PRINCIPLES OF CONFLICTS OF LAWS OF THE STATE OF WISCONSIN.

        SECTION 9.11
    Specific Enforcement.     

        (a)   The parties acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, and that monetary damages, even if available, would not be an adequate remedy therefor. It is accordingly agreed that, prior to the termination of this Agreement pursuant to ARTICLE VIII, the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the performance of terms and provisions of this Agreement in any court referred to in clause (a) of Section 9.12, without proof of actual damages (and each party hereby waives any requirement for the securing or posting of any bond in connection with such remedy), this being in addition to any other remedy to which they are entitled at law or in equity. The parties further agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to Law or inequitable for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy for any such breach.

        (b)   Notwithstanding anything to the contrary contained in this Agreement, each of the parties hereto agrees that it will not bring or support any action, cause of action, claim, cross-claim or third-party claim of any kind or description, whether in law or in equity, whether in contract or in tort or otherwise, against the Financing Sources in any way relating to this Agreement or any of the transactions contemplated by this Agreement in any forum other than the Supreme Court of the State of New York, County of New York, or, if under applicable Law exclusive jurisdiction is vested in the federal courts, the United States District Court for the Southern District of New York (and appellate courts thereof). The parties hereto further agree that all of the provisions of Section 9.13 relating to waiver of jury trial shall apply to any action, cause of action, claim, cross-claim or third party-claim referenced in this Section 9.11(b).

        (c)   Notwithstanding anything to the contrary contained in this Agreement, the Company agrees that neither it nor any of its Representatives or Affiliates shall have any rights or claims against any Financing Source in connection with or related to this Agreement, the Financing or the transactions contemplated hereby or thereby. In addition, no Financing Source shall have any liability or obligation to the Company or any of the Company's Representatives in connection with or related to this Agreement, the Financing or the transactions contemplated hereby or thereby, including for any consequential, special, exemplary, punitive or indirect damages (including any loss of profits, business or anticipated savings) or damages of a tortious nature. For avoidance of doubt, (i) in no event shall this Section 9.11(c) apply to Parent, whether before or after the Closing, and (ii) from and after the Closing, the foregoing shall not modify or alter in any respect any provision of any definitive loan documentation between or among Parent, the Company (or the Surviving Corporation), and any of

A-76

their Subsidiaries and any Financing Source entered into in connection with or as contemplated by this Agreement, and in the event of a conflict between the foregoing and any provision in any such definitive loan documentation, the provisions of such definitive loan documentation shall govern and control.


        SECTION 9.12
    Jurisdiction; Venue.     Each of the parties hereto (a) consents to submit itself to the exclusive jurisdiction of any Wisconsin State court or any Federal court located in the State of Wisconsin in the event any dispute arises out of this Agreement, the Initial Merger, the Subsequent Merger or any of the other transactions contemplated by this Agreement, (b) agrees that it will not attempt to deny or defeat such jurisdiction by motion or other request for leave from any such court and (c) agrees that it will not bring any action relating to this Agreement, the Initial Merger, the Subsequent Merger or any of the other transactions contemplated by this Agreement in any court other than any Wisconsin State court or any Federal court sitting in the State of Wisconsin.


        SECTION 9.13
    Waiver of Jury Trial.     Each party hereto hereby waives, to the fullest extent permitted by applicable Law, any right it may have to a trial by jury in respect of any suit, action or other proceeding arising out of this Agreement, the Initial Merger, the Subsequent Merger or any of the other transactions contemplated by this Agreement. Each party hereto (a) certifies that no representative, agent or attorney of any other party has represented, expressly or otherwise, that such party would not, in the event of any action, suit or proceeding, seek to enforce the foregoing waiver and (b) acknowledges that it and the other parties hereto have been induced to enter into this Agreement by, among other things, the mutual waiver and certifications in this Section 9.13.

        1.05.
    Fixing of Record Date.     The Board of Directors, the Chairman of the Board, the President or the Corporate Secretary or any other officer authorized by the Board of Directors, may fix in advance a date as the record date for one or more voting groups for any determination of stockholders entitled to notice of a stockholders' meeting, to demand a special meeting, to vote, or to take any other action, such date in any case to be not more than seventy (70) days and, in case of a meeting of stockholders, dividend or stock split, not less than ten (10) days prior to the meeting or action requiring such determination of stockholders, and may fix the record date for determining stockholders entitled to a share dividend or distribution. If within thirty (30) days after the corporation receives one or more written demands for a special stockholder meeting that purport to satisfy the requirements of Section 180.0702(1)(b) of the Wisconsin Business Corporation Law (or any successor provision) no record date has been fixed pursuant to the first sentence of this Section 1.05 for the determination of stockholders entitled to demand such a stockholder meeting, the record date for determining stockholders entitled to demand such meeting shall be the date that the first stockholder signed the demand. If no record date has been fixed pursuant to the first sentence of this Section 1.05 for the determination of stockholders entitled (A) to notice of or to vote at a meeting of stockholders prior to the time that notice of the meeting is mailed or otherwise delivered to stockholders, or (B) to consent to action without a meeting within thirty (30) days after the corporation receives the first written consent to stockholder action without a meeting, (a) the close of business on the day before the first notice of the meeting is mailed or otherwise delivered to stockholders or (b) the date that the first stockholder signed the first written consent to stockholder action without a meeting, respectively, shall be the record date for the determination of such stockholders. When a determination of stockholders entitled to vote at any meeting of stockholders has been made as provided in this section, such determination shall be applied to any postponement or adjournment thereof unless the Board of Directors fixes a new record date and except as otherwise required by law. A new record date must be set if a meeting is postponed or adjourned to a date more than 120 days after the date fixed for the original meeting.


        1.06.
    Quorum and Voting Requirements.     Except as otherwise provided in the Articles of Incorporation or in the Wisconsin Business Corporation Law, a majority of the votes entitled to be cast by shares entitled to vote as a separate voting group on a matter, represented in person or by proxy, shall constitute a quorum of that voting group for action on that matter at a meeting of stockholders. If a quorum exists, action on a matter, other than the election of directors, by a voting group is approved if the votes cast within the voting group favoring the action exceed the votes cast opposing the action unless a greater number of affirmative votes is required by the Wisconsin Business Corporation Law, the Articles of Incorporation, or any other provision of these Bylaws. If the Articles of Incorporation or the Wisconsin Business Corporation Law provide for voting by two (2) or more classes or voting groups on a matter, action on that matter is taken only when voted upon by each of those voting groups counted separately.

        1.07.
    Conduct of Meetings.     The Chairman of the Board, or in his absence or at his request, the President, and in the President's absence, a Vice President, and in their absence, any person chosen by the stockholders present shall call the meeting of the stockholders to order and shall act as chairperson of the meeting, and the Corporate Secretary shall act as secretary of all meetings of the stockholders, but, in the absence of the Corporate Secretary, the chairperson of the meeting may appoint any other person to act as secretary of the meeting.


        1.08.
    Voting at Meetings.     At all meetings of stockholders, a stockholder entitled to vote may vote in person or by proxy appointed as provided in the Wisconsin Business Corporation Law. The means by which a stockholder or the stockholder's authorized officer, director, employee, agent or attorney-in-fact may authorize another person to act for the stockholder by appointing the person as proxy include:

        An appointment of a proxy is effective when a signed appointment form or an electronic transmission of the appointment is received by the inspector of election or the officer or agent of the corporation authorized to tabulate votes. An appointment is valid for 11 months unless a different period is expressly provided in the appointment. An appointment of a proxy is revocable unless the appointment form or electronic transmission states that it is irrevocable and the appointment is coupled with an interest. The presence of a stockholder who has made an effective proxy appointment shall not of itself constitute a revocation.

        Voting at meetings of stockholders need not be by written ballot unless so determined by the Board of Directors, the Chairman of the Board, the President or the Corporate Secretary. Voting at meetings of stockholders shall be conducted by one or more inspectors of election appointed by the Board of Directors, the Chairman of the Board, the President or the Corporate Secretary. However, no director or person who is a candidate for the office of director shall be appointed as such inspector. The inspectors, or persons representing the inspector if the inspector is an institution, before entering upon the discharge of their duties, shall take and subscribe an oath faithfully to execute the duties of inspector at such meeting with strict impartiality and according to the best of their ability.


        1.09.
    Stockholder Unanimous Consent Without a Meeting.     Any action required by the Articles of Incorporation, Bylaws or any provision of law to be taken at a meeting of stockholders or any other action which may be taken at such a meeting may be taken without a meeting if consent in writing setting forth the action so taken shall be signed by all of the stockholders entitled to vote with respect to the subject matter thereof and such consent shall have the same force and effect as a unanimous vote.


        1.10.
    Stockholder Waiver of Notice.     A stockholder may waive any notice required by the Wisconsin Business Corporation Law, the Articles of Incorporation or these Bylaws before or after the date and time stated in the notice. The waiver shall be in writing and signed by the stockholder entitled to the notice, shall contain the same information that would have been required in the notice under the Wisconsin Business Corporation Law except that the time and place of meeting need not be stated, and shall be delivered to the corporation for inclusion in the corporate records. A stockholder's attendance at a meeting, in person or by proxy, waives objection to both of the following:

ARTICLE II.
BOARD OF DIRECTORS

        2.01.    Number.     The number of directors constituting the whole Board of Directors shall be such number as shall be fixed from time to time by the affirmative vote of the whole Board but in no event shall the number be less than three. The number of directors at any time constituting the whole Board shall not be reduced so as to shorten the term of any director then in office. Directors need not be stockholders of the corporation.


        2.02.
    Term of Office.     The directors shall hold office until the next annual meeting of stockholders at which their respective terms of office shall expire and until their respective successors are duly elected and qualified.


        2.03.
    Election and Tenure.     Unless action is taken without a meeting under these Bylaws, directors shall be elected by a plurality of the votes cast by the shares entitled to vote in the election at a stockholders meeting at which a quorum is present. Each director shall hold office until the end of such director's term and until such director's successor has been elected, or until such director's prior death, resignation or removal. A director may resign at any time by filing a written resignation with the Corporate Secretary of the corporation.


        2.04.
    Removal.     If cumulative voting for directors is not authorized by the Articles of Incorporation, any director or directors may be removed from office by the stockholders if the number of votes cast to remove the director exceeds the number cast not to remove him or her, taken at a meeting of stockholders called for that purpose (unless action is taken without a meeting under Section 1.09 of these Bylaws), provided that the meeting notice states that the purpose, or one of the purposes, of the meeting is removal of the director. The removal may be made with or without cause unless the Articles of Incorporation or these Bylaws provide that directors may be removed only for cause. If a director is elected by a voting group of stockholders, only the stockholders of that voting group may participate in the vote to remove that director.


        2.05.
    Vacancies.     Any vacancy occurring in the Board of Directors, including a vacancy created by an increase in the number of directors, may be filled by the stockholders or the Board of Directors. If the directors remaining in office constitute fewer than a quorum of the Board, the directors may fill a vacancy by the affirmative vote of a majority of all directors remaining in office. Each director so elected shall hold office for a term expiring at the next annual stockholders' meeting.


        2.06.
    Regular Meetings.     Regular meetings of the Board of Directors and any committee thereof shall be held at such time and place, either within or without the State of Wisconsin, as may from time to time be fixed by the Board or such committee without other notice than the schedule prepared by the Corporate Secretary or the resolution or other action of the Board or committee establishing the time and place of such regular meetings.


        2.07.
    Special Meetings.     Special meetings of the Board of Directors may be called by or at the request of the Board of Directors, the Executive Committee, the Chairman of the Board, the President, any committee designated by the Board with specific authority to do such or any two (2) directors. Special meetings of any committee may be called by or at the request of the foregoing persons or the chairman of the committee. The persons calling any special meeting of the Board of Directors or

4

committee may fix any place, either within or without the State of Wisconsin, as the place for holding any special meeting called by them, and if no other place is fixed the place of meeting shall be the principal business office of the corporation.


        2.08.
    Meetings by Telephone or Other Communication Technology.     (a) Any or all directors may participate in a regular or special meeting of the Board of Directors or in a committee meeting by, or conduct the meeting through the use of, telephone or any other means of communication by which either: (i) all participating directors may simultaneously hear each other during the meeting or (ii) all communication during the meeting is immediately transmitted to each participating director, and each participating director is able to immediately send messages to all other participating directors.

        (b)   If a meeting will be conducted through the use of any means described in paragraph (a), all participating directors shall be informed that a meeting is taking place at which official business may be transacted. A director participating in a meeting by any means described in paragraph (a) is deemed to be present in person at the meeting.


        2.09.
    Notice of Meetings.     Notice of each meeting of the Board of Directors (unless otherwise provided in or pursuant to Section 2.06 of these Bylaws) shall be given by written notice delivered personally or mailed or given by telephone or telegram to each director at his business address or at such other address as such director shall have designated in writing filed with the Corporate Secretary, in each case not less than 6 hours prior thereto. If mailed, such notice shall be deemed to be delivered when deposited in the United States mail so addressed, with postage thereon prepaid. If notice be given by telegram, such notice shall be deemed to be delivered when the telegram is delivered to the telegraph company; if by telephone, at the time the call is completed. Whenever any notice whatever is required to be given to any director of the corporation under the Articles of Incorporation, Bylaws or any provision of law, a waiver thereof in writing, signed at any time, whether before or after the time of meeting, by the director entitled to such notice, shall be deemed equivalent to the giving of such notice. The attendance of a director at a meeting shall constitute a waiver of notice of such meeting, except where a director attends a meeting and objects thereat to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the Board need be specified in the notice or waiver of notice of such meeting.


        2.10.
    Quorum.     Except as otherwise provided by the Wisconsin Business Corporation Law or these Bylaws, a majority of the number of directors as provided in or pursuant to Section 2.01 shall constitute a quorum of the Board of Directors, and a majority of the number of directors appointed to serve on a committee shall constitute a quorum of the committee. If at any meeting of the Board of Directors or any committee thereof there shall be less than a quorum present, a majority of the directors present may adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall have been obtained, when any business may be transacted which might have been transacted at the meeting as first convened had there been a quorum.


        2.11.
    Manner of Acting.     The affirmative vote of a majority of the directors present at a meeting at which a quorum is present shall be the act of the Board of Directors or any committee thereof unless the affirmative vote of a greater number is otherwise required by the Wisconsin Business Corporation Law, the Articles of Incorporation, the Bylaws or any provision of law.


        2.12.
    Committees.     The Board of Directors, by resolution adopted by the affirmative vote of a majority of all the directors then in office, may create one or more committees, each committee to consist of two (2) or more directors appointed by the Board of Directors to serve as members of the committee, which to the extent provided in the resolution as initially adopted, and as thereafter supplemented or amended by further resolution adopted by a like vote, may exercise the authority of the Board of Directors. Notwithstanding the foregoing, no committee may: (a) authorize distributions; (b) approve or propose to stockholders action that the Wisconsin Business Corporation Law requires

5

be approved by stockholders; (c) fill vacancies on the Board of Directors or any of its committees, except that the Board of Directors may provide by resolution that any vacancies on a committee shall be filled by the affirmative vote of a majority of the remaining committee members; (d) amend the Articles of Incorporation; (e) adopt, amend or repeal Bylaws; (f) approve a plan of merger not requiring stockholder approval; (g) authorize or approve reacquisition of shares, except according to a formula or method prescribed by the Board of Directors; or (h) authorize or approve the issuance or sale or contract for sale of shares, or determine the designation and relative rights, preferences and limitations of a class or series of shares, except within limits prescribed by the Board of Directors.

        Unless otherwise provided by the Board of Directors, members of any committee shall serve at the pleasure of the Board of Directors. The Board of Directors may elect one or more of its members as alternate members of any such committee who may take the place of any absent member or members at any meeting of such committee, upon request by the Chairman of the Board or upon request by the chairperson of such meeting. Each such committee shall fix its own rules (consistent with the Wisconsin Business Corporation Law, the Articles of Incorporation and these Bylaws) governing the conduct of its activities and shall make such reports to the Board of Directors of its activities as the Board of Directors may request. Unless otherwise provided by the Board of Directors in creating a committee, a committee may employ counsel, accountants and other consultants to assist it in the exercise of authority.

        The provisions of Section 2.09 shall also apply to notice and waiver of notice of meetings of any committee of the Board of Directors.


        2.13.
    Compensation.     The Board of Directors, by affirmative vote of a majority of the directors then in office, and irrespective of any personal interest of any of its members, may (a) establish reasonable compensation of all directors for services to the corporation as directors, officers or otherwise, and the manner and time and payment thereof, (b) provide for reasonable pensions, disability or death benefits, and other benefits or payments, to directors, officers and employees and to their estates, families, dependents or beneficiaries on account of prior services rendered by such directors, officers and employees to the corporation, and (c) provide for reimbursement of reasonable expenses incurred in the performance of directors' duties.


        2.14.
    Presumption of Assent.     A director who is present and is announced as present at a meeting of the Board of Directors or a committee thereof at which action on any corporate matter is taken shall be presumed to have assented to the action taken unless (a) the director objects at the beginning of the meeting or promptly upon his or her arrival to holding the meeting or transacting business at the meeting, or (b) the director's dissent or abstention from the action taken is entered in the minutes of the meeting, or (c) the director delivers his or her written notice of dissent or abstention to the presiding officer of the meeting before the adjournment thereof or to the corporation immediately after the adjournment of the meeting, or (d) the director dissents or abstains from an action taken, minutes of the meeting are prepared that fail to show the director's dissent or abstention and the director delivers to the corporation a written notice of that failure promptly after receiving the minutes. Such right to dissent or abstain shall not apply to a director who voted in favor of an action.


        2.15.
    Director Unanimous Consent Without a Meeting.     Any action required or permitted by the Articles of Incorporation, these Bylaws or any provision of law to be taken at a Board of Directors meeting or committee meeting may be taken without a meeting if the action is taken by all members of the Board or committee. The action shall be evidenced by one or more written consents describing the action taken, signed by each director and retained by the corporation. Action taken hereunder is effective when the last director signs the consent, unless the consent specifies a different effective date. A consent signed hereunder has the effect of a unanimous vote taken at a meeting at which all directors or committee members were present, and may be described as such in any document.

Except as provided in the preceding sentence, the resignation or removal is subject to any remedies provided by any contract between the officer and the corporation or otherwise provided by law. Appointment shall not of itself create contract rights.


        3.03.
    Vacancies.     A vacancy in any office because of death, resignation, removal or otherwise, may be filled by the Board of Directors or the Chief Executive Officer, as appropriate. The Board of Directors or the Chief Executive Officer, as appropriate, may, from time to time, omit to appoint one or more officers or may omit to fill a vacancy, and in such case, the designated duties of such officer, unless otherwise provided in these Bylaws, shall be discharged by the Chief Executive Officer or such other officers as he or she may designate.

CERTIFICATES FOR SHARES AND THEIR TRANSFER

        4.01.    Stock Certificates and Facsimile Signatures.     The certificates for shares of stock of the corporation shall be signed either manually or by facsimile signature by the Chief Executive Officer, the President or a Vice President, and by the Corporate Secretary or an Assistant Corporate Secretary of the corporation, or any other officer or officers that the Board of Directors designates, and may be sealed with the seal of the corporation.

        The certificates for shares shall be countersigned and registered either manually or by facsimile signature in such manner, if any, as the Board of Directors may from time to time prescribe. The transfer agent and the registrar may, but need not be, the same person or agency. In the event that the corporation or its agent is acting in the dual capacity of transfer agent and registrar, a single manual or facsimile signature may be used.

        In case any such person acting as an officer, transfer agent or registrar, who has signed, or whose facsimile signature has been placed upon such certificate, shall have ceased to be such officer, transfer agent or registrar, before such certificate is issued, it may be used by the corporation with the same effect as if such person had not ceased to be such at the date of its issue.


        4.02.
    Transfer of Stock.     The shares of stock of the corporation shall be transferable on the books of the corporation upon request by the holders thereof or by duly authorized attorney, upon surrender and cancellation of certificates for a like number of shares of the same class and series of stock, with duly executed assignment and power of transfer endorsed thereon or attached thereto, and with such proof of the authenticity of the signature as the corporation or its agents may reasonably require.

        Prior to due presentment of a certificate for shares for registration of transfer the corporation may treat the registered owner of such shares as the person exclusively entitled to vote, to receive notifications and otherwise to have and exercise all the rights and powers of an owner. Where a certificate for shares is presented to the corporation with a request to register for transfer, the corporation shall not be liable to the owner or any other person suffering loss as a result of such registration of transfer if (a) there were on or with the certificate the necessary endorsements, and (b) the corporation had no duty to inquire into adverse claims or has discharged any such duty. The corporation may require reasonable assurance that said endorsements are genuine and effective and in compliance with such other regulations as may be prescribed by or under the authority of the Board of Directors.


        4.03.
    Lost, Destroyed or Stolen Certificates.     Where the owner claims that his certificate for shares has been lost, destroyed or wrongfully taken, a new certificate shall be issued in place thereof if the owner (a) so requests before the corporation has notice that such shares have been acquired by a bona fide purchaser, (b) files with the corporation a sufficient indemnity bond and (c) satisfies such other reasonable requirements as may be prescribed by or under the authority of the Board of Directors.


        4.04.
    Shares Without Certificates.     The Board of Directors may authorize the issuance of any shares of any of its classes or series without certificates. The authorization does not affect shares already represented by certificates until the certificates are surrendered to the corporation. Within a reasonable time after the issuance or transfer of shares without certificates, the corporation shall send the stockholder a written statement that includes (1) all of the information required on share certificates and (2) any transfer restrictions applicable to the shares.

        5.03.
    Legal Enforceability.     The rights provided to any person by the terms of this Article V shall be legally enforceable against the corporation by such person, who shall be presumed to have relied on the provisions of this Article V in undertaking or continuing any of the positions with the corporation or other enterprise referred to in Section 5.01.


        5.04.
    Limitation on Modification or Termination.     No modification or termination of this Article V shall be effected which would impair any rights hereunder arising at any time out of events occurring prior to such modification or termination.


        5.05.
    Non-Exclusive Bylaw.     This Article V is not intended to be exclusive and accordingly shall not be construed as impairing in any way the power and authority of the corporation, to the extent legally permissible without regard to this Article V, in its discretion to indemnify or agree to indemnify, or to purchase insurance indemnifying, any employee, agent or other person.

        (c)   The termination of a proceeding by judgment, order, settlement or conviction, or upon a plea of no contest or an equivalent plea, does not, by itself, create a presumption that indemnification of the director or officer is not required under this Section.

        6.07.
    Limitations on Indemnification.     (a) Regardless of the existence or rights under these Bylaws and additional rights to indemnification under any agreement with the corporation, the corporation shall not indemnify a director or officer, or permit a director or officer to retain any allowance of expenses, unless it is determined by or on behalf of the corporation that the director or officer did not breach or fail to perform a duty he or she owes to the corporation which constitutes conduct under Section 6.02(a)(1), (2), (3) or (4). A director or officer who is a party to the same or related proceedings for which indemnification or an allowance of expenses is sought may not participate in a determination under this subsection.

Board of Directors
Wisconsin Energy Corporation
231 West Michigan Street
Milwaukee, WI 53201

Members of the Board of Directors:

        We understand that Wisconsin Energy Corporation (the "Company") intends to enter into a transaction (the "Proposed Transaction") with Integrys Energy Group ("Integrys") pursuant to which (i) a to-be-formed wholly-owned subsidiary of the Company ("Merger Sub") will merge with and into Integrys, with Integrys surviving the merger as the surviving corporation ("Initial Surviving Merger Sub") and then (ii) Initial Surviving Merger Sub will merge with and into a second to-be-formed wholly-owned subsidiary of the Company ("Subsequent Merger Sub"), with Subsequent Merger Sub surviving the merger as the surviving corporation (collectively, the "Mergers"). Pursuant to the Mergers, each share of Integrys Common Stock issued and outstanding immediately prior to the Effective Time will be canceled and converted into the right to receive (1) $18.58 in cash, without interest (the "Cash Consideration") and (2) 1.128 shares of the Company's common stock, par value $0.01 (the "Stock Consideration" and, together with the Cash Consideration, the "Merger Consideration"). The terms and conditions of the Proposed Transaction are set forth in more detail in the draft of the Agreement and Plan of Merger dated of as June 21, 2014 (the "Agreement") by and among the Company and Integrys. The summary of the Proposed Transaction set forth above is qualified in its entirety by the terms of the Agreement.

        We have been requested by the Board of Directors of the Company to render our opinion with respect to the fairness, from a financial point of view, to the Company of the consideration to be paid by the Company in the Proposed Transaction. We have not been requested to opine as to, and our opinion does not in any manner address, the Company's underlying business decision to proceed with or effect the Proposed Transaction or the likelihood of consummation of the Proposed Transaction. In addition, we express no opinion on, and our opinion does not in any manner address, the fairness of the amount or the nature of any compensation to any officers, directors or employees of any parties to the Proposed Transaction, or any class of such persons, relative to the consideration paid in the Proposed Transaction or otherwise.

        In arriving at our opinion, we reviewed and analyzed: (1) a draft of the Agreement, dated as of June 21, 2014 and the specific terms of the Proposed Transaction; (2) publicly available information concerning the Company and Integrys that we believe to be relevant to our analysis, including each of (i) their respective Annual Reports on Form 10-K for the fiscal year ended December 31, 2013 and Quarterly Reports on Form 10-Q for the fiscal quarters ended March 31, 2014 and other relevant filings with the Securities and Exchange Commission; and (ii) Federal Energy Regulatory Commission ("FERC") Form No.1 and FERC Electric & Gas Form No. 3Q filings for Integrys; (3) financial and operating information with respect to the business, operations and prospects of the Company furnished to us by management of the Company, including financial projections of the Company prepared by management of the Company (the "Company Projections"); (4) financial and operating information with respect to the business, operations and prospects of Integrys furnished to us by management of the Company, including financial projections of Integrys prepared by management of the Company (the "Company's Integrys Projections"); (5) the trading history of the Company's common stock from

Table of Contents

June 20, 2012 to June 20, 2014 and the trading history of Integrys' common stock from June 20, 2012 to June 20, 2014 and a comparison of each of their trading histories with those of other companies that we deemed relevant; (6) a comparison of the historical financial results and present financial condition of the Company and Integrys with each other and with those of other companies that we deemed relevant; (7) a comparison of the financial terms of the Proposed Transaction with the financial terms of certain other transactions that we deemed relevant; (8) the pro forma impact of the Proposed Transaction on the future financial performance of the combined company; (9) the relative contributions of the Company and Integrys to the historical and future financial performance of the combined company on a pro forma basis. In addition, we have had discussions with the management of the Company and Integrys concerning the Company's and Integrys' business, operations, assets, liabilities, financial condition and prospects and have undertaken such other studies, analyses and investigations as we deemed appropriate.

        In arriving at our opinion, we have assumed and relied upon the accuracy and completeness of the financial and other information used by us without any independent verification of such information (and have not assumed responsibility or liability for any independent verification of such information) and have further relied upon the assurances of the management of the Company that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the Company Projections and the Company's Integrys Projections, upon the advice of the Company, we have assumed that such projections have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of the Company as to the future financial performance of the Company and Integrys and that the Company and Integrys will perform substantially in accordance with such projections. We assume no responsibility for and we express no view as to any such projections or estimates or the assumptions on which they are based. In arriving at our opinion, we have not conducted a physical inspection of the properties and facilities of the Company or Integrys and have not made or obtained any evaluations or appraisals of the assets or liabilities of the Company or Integrys. Our opinion necessarily is based upon market, economic and other conditions as they exist on, and can be evaluated as of, the date of this letter. We assume no responsibility for updating or revising our opinion based on events or circumstances that may occur after the date of this letter. We express no opinion as to the prices at which shares of common stock of the Company would trade following the announcement of the Proposed Transaction. Our opinion should not be viewed as providing any assurance that the market value of the shares of common stock of the Company to be held by the stockholders of the Company after the consummation of the Proposed Transaction will be in excess of the market value of common stock of the Company owned by such stockholders at any time prior to the announcement or consummation of the Proposed Transaction.

        We have assumed that the executed Agreement will conform in all material respects to the last draft reviewed by us. In addition, we have assumed the accuracy of the representations and warranties contained in the Agreement and all agreements related thereto. We have also assumed, upon the advice of the Company, that all material governmental, regulatory and third party approvals, consents and releases for the Proposed Transaction will be obtained within the constraints contemplated by the Agreement and that the Proposed Transaction will be consummated in accordance with the terms of the Agreement without waiver, modification or amendment of any material term, condition or agreement thereof, and that the financing for the Proposed Transaction will be obtained in accordance with the terms described by the Company. Additionally, we have assumed, upon the advice of the Company, that the Proposed Transaction will qualify as a "reorganization" for United States federal income tax purposes. We do not express any opinion as to any tax or other consequences that might result from the Proposed Transaction, nor does our opinion address any legal, tax, regulatory or accounting matters, as to which we understand that the Company has obtained such advice as it deemed necessary from qualified professionals.

Table of Contents

        Based upon and subject to the foregoing, we are of the opinion as of the date hereof that, from a financial point of view, the consideration to be paid by the Company in the Proposed Transaction is fair to the Company.

        We have acted as financial advisor to the Company in connection with the Proposed Transaction and will receive a fee for our services a portion of which is payable upon rendering this opinion and a substantial portion of which is contingent upon the consummation of the Proposed Transaction. In addition, the Company has agreed to reimburse a portion of our expenses and indemnify us for certain liabilities that may arise out of our engagement. We have performed various investment banking and financial services for the Company in the past, and expect to perform such services in the future, and have received, and expect to receive, customary fees for such services. Specifically, in the past two years, we have performed the following investment banking and financial services: (i) acted as active joint bookrunner and billing and delivery agent of $250 million senior debentures for Wisconsin Electric Power Company, (ii) acted as joint lead arranger in connection with the refinancing of $1.25 billion of revolving credit facilities for the Company and its affiliates, and (iii) served as purchase agent for the Company's open market share repurchase program. We have not performed services for Integrys in the past two years.

        Barclays Capital Inc. and its affiliates engage in a wide range of businesses from investment and commercial banking, lending, asset management and other financial and non-financial services. In the ordinary course of our business, we and our affiliates may actively trade and effect transactions in the equity, debt and/or other securities (and any derivatives thereof) and financial instruments (including loans and other obligations) of the Company and Integrys for our own account and for the accounts of our customers and, accordingly, may at any time hold long or short positions and investments in such securities and financial instruments.

        This opinion, the issuance of which has been approved by our Fairness Opinion Committee, is for the use and benefit of the Board of Directors of the Company and is rendered to the Board of Directors in connection with its consideration of the Proposed Transaction. This opinion is not intended to be and does not constitute a recommendation to any stockholder of the Company as to how such stockholder should vote with respect to the Proposed Transaction.

    Very truly yours,

The Board of Directors
Integrys Energy Group, Inc.
200 East Randolph Street
Chicago, IL 60601-6207

Dear Members of the Board:

        We understand that Integrys Energy Group, Inc., a Wisconsin corporation ("Company"), and Wisconsin Energy Corporation, a Wisconsin corporation ("Buyer"), propose to enter into an Agreement and Plan of Merger dated as of June 23, 2014 (the "Agreement"), pursuant to which Buyer will acquire Company (the "Transaction"). Pursuant to the Agreement, Buyer will form two direct, wholly owned subsidiaries of Buyer as Wisconsin corporations (such subsidiaries, collectively, "Merger Subsidiaries"), and one such subsidiary will merge with and into Company, with Company surviving the merger as the surviving corporation (the "Merger"). Each outstanding share of the common stock, par value $1.00 per share, of Company ("Company Common Stock"), other than shares of Company Common Stock that are owned by Company as treasury stock and shares of Company Common Stock, if any, that are owned by Buyer or the Merger Subsidiaries immediately prior to the Merger, but including shares of Company Common Stock held by the Company Rabbi Trust, upon consummation of the Merger, will be converted into the right to receive (i) $18.58 in cash (the "Cash Consideration") and (ii) 1.128 shares of the common stock, par value $0.01 per share, of Buyer ("Buyer Common Stock") (such number of shares so issuable, the "Stock Consideration" and, together with the Cash Consideration, the "Consideration"). The terms and conditions of the Transaction are more fully set forth in the Agreement. For purposes hereof, "Excluded Holders" shall refer to the Company, Buyer or any Merger Subsidiary, each in their capacity as holders of any Company Common Stock.

        You have requested our opinion as of the date hereof as to the fairness, from a financial point of view, to holders of Company Common Stock (other than Excluded Holders) of the Consideration to be paid to such holders.

        In connection with this opinion, we have:

C-1


Table of Contents

        We have assumed and relied upon the accuracy and completeness of the foregoing information, without independent verification of such information. We have not conducted any independent valuation or appraisal of any of the assets or liabilities (contingent or otherwise) of Company or Buyer or concerning the solvency or fair value of Company or Buyer, and we have not been furnished with any such valuation or appraisal. Management of Company has advised us that the "Base" case financial forecast provided to us represents the best currently available estimates and judgments as to the future financial performance of Company and, accordingly, for purposes of our analyses in connection with this opinion, you have directed us to utilize the "Base" case financial forecast. With respect to the financial forecasts utilized in our analyses, including those related to the illustrative synergies and other benefits anticipated by management of Company to be realized from the Transaction, as well as Buyer's financial forecasts, we have assumed, at the direction of Company, that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments as to the future financial performance of Company and Buyer, respectively, and such synergies and other benefits. We assume no responsibility for and express no view as to any such forecasts or the assumptions on which they are based.

        Further, our opinion is necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to us as of, the date hereof. We assume no responsibility for updating or revising our opinion based on circumstances or events occurring after the date hereof. We do not express any opinion as to the prices at which shares of Company Common Stock or Buyer Common Stock may trade at any time subsequent to the announcement of the Transaction. In connection with our engagement, we were not authorized to, and we did not, solicit indications of interest from third parties regarding a potential transaction with Company. In addition, our opinion does not address the relative merits of the Transaction as compared to any other transaction or business strategy in which Company might engage or the merits of the underlying decision by Company to engage in the Transaction.

        In rendering our opinion, we have assumed, with the consent of Company, that the Transaction will be consummated on the terms described in the Agreement, without any waiver or modification of any terms or conditions material to our analysis. Representatives of Company have advised us, and we have assumed, that the Agreement, when executed, will conform to the draft reviewed by us in all material respects. We also have assumed, with the consent of Company, that obtaining the necessary governmental, regulatory or third-party approvals and consents for the Transaction will not have an adverse effect on Company, Buyer or the Transaction. We further have assumed, with the consent of Company, that the Transaction will qualify for U.S. federal income tax purposes as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended. We do not express any opinion as to any tax or other consequences that might result from the Transaction, nor does our opinion address any legal, tax, regulatory or accounting matters, as to which we understand that Company obtained such advice as it deemed necessary from qualified professionals. We express no view or opinion as to any terms or other aspects (other than the Consideration to the extent expressly specified herein) of the Transaction, including, without limitation, the form or structure of the Transaction or any agreements or arrangements entered into in connection with, or contemplated by, the Transaction. In addition, we express no view or opinion as to the fairness of the amount or nature of, or any other aspects relating to, the compensation to any officers, directors or employees of any parties to the Transaction, or class of such persons, relative to the Consideration or otherwise.

        Lazard Frères & Co. LLC ("Lazard") is acting as financial advisor to Company in connection with the Transaction and will receive a fee for such services, a portion of which is payable upon the rendering of this opinion and a substantial portion of which is contingent upon the closing of the

Transaction. We in the past have provided, currently are providing and in the future may provide certain investment banking services to Company, for which we have received and may receive compensation. In addition, in the ordinary course, Lazard and its respective affiliates and employees may trade securities of Company, Buyer and certain of their respective affiliates for their own accounts and for the accounts of their customers, may at any time hold a long or short position in such securities, and may also trade and hold securities on behalf of Company, Buyer and certain of their respective affiliates. The issuance of this opinion was approved by the Opinion Committee of Lazard.

        Our engagement and the opinion expressed herein are for the benefit of the Board of Directors of Company (in its capacity as such) and our opinion is rendered to the Board of Directors of Company in connection with its evaluation of the Transaction. Our opinion is not intended to and does not constitute a recommendation to any shareholder of Company or Buyer as to how such shareholder should vote or act with respect to the Transaction or any matter relating thereto.

        Based on and subject to the foregoing, we are of the opinion that, as of the date hereof, the Consideration to be paid to holders of Company Common Stock (other than Excluded Holders) in the Transaction is fair, from a financial point of view, to such holders.

    Very truly yours,
