FOR IMMEDIATE RELEASE

ACI WORLDWIDE TO ACQUIRE S1 CORPORATION

Creates Global Leader in Enterprise Payments Solutions

NEW YORK and NORCROSS, Ga., October 3, 2011 – ACI Worldwide, Inc. (Nasdaq: ACIW) and S1 Corporation (Nasdaq: SONE) today announced that they have entered into a definitive transaction agreement that will create a full-service global leader of financial and payments solutions. Under the agreement, ACI will acquire S1 for a blended value of $9.55 per share as of September 30, 2011, consisting of $6.62 per share in cash and 0.1064 shares of ACI common stock, assuming full proration, which represents an increase of $0.42 per share in cash from ACI’s previous offer. The boards of directors of both companies have approved the transaction.

“We are pleased to have reached this agreement with S1, and believe that together we will create a leader in the global enterprise payments industry,” said Philip G. Heasley, President and Chief Executive Officer of ACI. “The combined company will have enhanced scale, breadth and additional capabilities, as well as a complementary suite of products that will better serve the entire spectrum of financial institutions, processors and retailers. Stockholders of both companies will benefit from the significant upside potential of a larger, more diversified company that is strongly positioned in a wide range of markets.”

Continued Mr. Heasley, “S1 has a loyal and committed workforce, which will be a great complement to our own employee base. We believe that the size, scope, geographic reach and expanded technical expertise of the combined company will offer even greater opportunities to our employees world-wide. In addition, S1’s products and rich set of capabilities will further enhance our existing offerings. We look forward to working with S1 to complete this acquisition in order to build a greater company for our customers and employees and to deliver enhanced results to stockholders.”


“With the significant improvements in the transaction terms and conditions, S1’s Board of Directors unanimously concluded that combining with ACI is in the best interests of S1’s stockholders, as it provides a substantial premium for their investment and the opportunity to participate further in this powerful combination,” said John W. Spiegel, Chairman of the Board of Directors of S1. “On behalf of S1’s Board and management team, I would like to thank our customers for their ongoing support and express our deep appreciation to our employees, whose hard work and dedication has been instrumental in making S1 the outstanding company it is today.”

Complementary Offerings and Global Platform to Drive Long-Term Value Creation

Highly Complementary Products and Solutions: Following the close of the transaction, the combined company will be a full-service global leader of financial and payments solutions with significant scale. ACI’s and S1’s products are highly complementary and ACI expects to leverage S1’s success with a range of financial institutions and retailers, as well as S1’s strong global capabilities. The combined company will be well positioned to address both emerging and developed payments markets, and will provide a rich set of capabilities across the most unified payments solution to serve Retail Banking, Wholesale Banking, Processors and Retailers. The combined company will remain focused on delivering business agility without compromising the trust of its combined customers.

Significant Synergy Opportunities and Financial Strength: The pro forma financial implications of the transaction are compelling. ACI anticipates that with S1 it will achieve annual cost synergies of approximately $30 million. In addition, the increased global scale and expected cost savings are expected to generate margin expansion. The transaction is expected to be accretive to full year earnings in 2012.

For the last twelve months ending June 30, 2011, the companies generated pro forma combined revenue of $683 million, adjusted EBITDA of $123 million and free cash flow of $90 million. The combined company is expected to have a strong financial profile, including a solid balance sheet with substantial liquidity. ACI will have a robust liquidity


position with more than $150 million of combined cash remaining on the balance sheet and more than $65 million of availability under a new credit facility at closing. This ample liquidity and high free cash flow generation are expected to support long-term growth.

Terms of the Transaction

ACI will acquire S1 for approximately $360 million in cash and 5.8 million ACI shares. Under the terms of the transaction, S1 stockholders can elect to receive $10.00 in cash or 0.3148 shares of ACI stock for each S1 share they own, subject to proration, such that in the aggregate 33.8% of S1 shares are exchanged for ACI shares and 66.2% are exchanged for cash.

ACI will amend its pending exchange offer to reflect the terms of the definitive agreement. The complete terms and conditions of the exchange offer will be set forth in the amended prospectus/offer to exchange on Form S-4 that ACI expects to file with the Securities and Exchange Commission (the “SEC”) by October 13, 2011.

Based on the closing sales price of ACI common stock on September 30, 2011, the blended value of ACI’s proposal is $9.55 per S1 share, assuming full proration. However, the equity capital markets have been highly volatile since July 26, 2011 and market prices for ACI shares and S1 shares have fluctuated and can be expected to continue to fluctuate. S1 stockholders are urged to obtain current trading price information prior to making any decision with respect to the exchange offer.

S1’s Board of Directors recommends that all S1 stockholders tender their shares into ACI’s amended exchange offer. ACI had previously extended the expiration date of the exchange offer to 5:00 p.m. Eastern Time on October 31, 2011, unless further extended.

Offering materials will also be available on the SEC’s website at www.sec.gov.
