Company Urges Shareholders to Vote Today "FOR" the Election of Each of its Nominees and “FOR” ALL Proposals Listed on the WHITE Proxy Card

NextGen Healthcare, Inc. (Nasdaq: NXGN), a leading provider of ambulatory-focused technology solutions, today urged shareholders to vote "FOR" the election of each of its highly qualified director nominees and “FOR” ALL other proposals listed on the Company’s WHITE proxy card, including the Company’s reincorporation into Delaware and the elimination of cumulative voting in the election of directors. The Company also announced that independent proxy advisory firm, Egan-Jones Proxy Services (“Egan-Jones”), issued a report on October 7, 2021 recommending that NextGen Healthcare shareholders vote on the Company’s WHITE proxy card.

Egan-Jones is the third proxy advisory firm to support the Company, joining Institutional Shareholder Services (“ISS”) and Glass, Lewis & Co. (“Glass Lewis”) who also issued reports recommending that NextGen Healthcare shareholders vote on the Company’s WHITE proxy card.

The Company’s Board of Directors thanks NextGen Healthcare shareholders for their consideration and support, and issued the following statement:

New leadership has implemented far-reaching changes that have transformed NextGen Healthcare into a market leader well positioned for accelerating growth and significant, sustainable value creation.

• Capital allocation has been reprioritized to R&D and strategic M&A, creating a premier integrated solutions and services platform and extending the Company’s reach into high-growth markets.
• A majority of the Board, five of the Company’s nine director nominees, will be new to the Board over the past four years, further advancing the Board’s diversity across race, gender, age and tenure.
• All of the Board’s director nominees have skills and expertise that are relevant to NextGen Healthcare’s strategic execution. These nominees are capable, independent thinkers who are committed to serving the best interests of ALL shareholders.
• Of the Company’s 12-member executive leadership team 10 are new to NextGen Healthcare since 2016. The addition of David Sides as the Company’s new CEO creates a powerhouse management team with the talent, track record and experience to continue fueling the Company’s growth.
• Employee engagement and incentive plans have been redefined, leading to all-time highs in engagement scores and substantial productivity improvements.

All three leading independent proxy advisory firms, ISS, Glass Lewis and Egan-Jones recognize the benefits these changes have created and recommend that shareholders vote on the Company’s WHITE proxy card in connection with NextGen Healthcare’s Annual Meeting.

The support from ISS, Glass Lewis and Egan-Jones as well as from independent sell-side analysts, employees and clients validates our success in reinvigorating the Company. Measurable improvements in the Company’s financial and operating performance also show that we are on the right track. Revenue growth has been accelerating at an increasing rate. Recurring revenue and subscription revenue streams are growing and will support margin expansion. We have strong operating cash flow and no debt. We are achieving significant new clients wins again and again, with new clients representing approximately 25% of our bookings.

We have appreciated the opportunity to talk with our shareholders about this progress and the exciting opportunities we have for growth and enhanced value creation.

Don’t let Sheldon Razin, the Company’s founder and long-tenured, 47-year director, derail NextGen Healthcare’s significant transformation and the momentum underway.

Forward Looking Statements

This communication may contain forward-looking statements within the meaning of the federal securities laws, including but not limited to, statements regarding future events including but not limited to the COVID-19 pandemic, developments in the healthcare sector and regulatory framework, the Company's future performance, as well as management's expectations, beliefs, intentions, plans, estimates or projections relating to the future (including, without limitation, statements concerning revenue, net income, and earnings per share). Risks and uncertainties exist that may cause the results to differ materially from those set forth in these forward-looking statements. Factors that could cause the anticipated results to differ from those described in the forward-looking statements and additional risks and uncertainties are set forth in Part I, Item A of our most recent Annual Report on Form 10-K and subsequently filed Quarterly Reports on Form 10-Q, including but not limited to: volatility and uncertainty in the global economy, financial markets and on our customers in light of the continuing COVID-19 pandemic, including the potential (i) slowdown or shutdown of preventive and elective medical procedures, (ii) delay in the contracting for additional products and services by our customers and (iii) delay in the sales cycle for new customers; a determination by the jury that the Company has liability in litigation advanced by a former director and shareholder; the volume and timing of systems sales and installations; length of sales cycles and the installation process; the possibility that products will not achieve or sustain market acceptance; seasonal patterns of sales and customer buying behavior; impact of incentive payments under The American Recovery and Reinvestment Act on sales and the ability of the Company to meet continued certification requirements; uncertainties related to the future impact of U.S. tax reform; the impact of governmental and regulatory agency investigations; the development by competitors of new or superior technologies; the timing, cost and success or failure of new product and service introductions, development and product upgrade releases; undetected errors or bugs in software; product liability; changing economic, political or regulatory influences in the health-care industry; changes in product-pricing policies; availability of third-party products and components; competitive pressures including product offerings, pricing and promotional activities; the Company's ability or inability to attract and retain qualified personnel; the impact of any proxy contest at the 2021 Annual Meeting of Shareholders; possible regulation of the Company's software by the U.S. Food and Drug Administration; changes of accounting estimates and assumptions used to prepare the prior periods' financial statements; disruptions caused by acquisitions of companies, products, or technologies; the extent to which the COVID-19 pandemic and measures taken in response thereto could adversely affect our financial condition and results of operations; and general economic conditions. A significant portion of the Company's quarterly sales of software product licenses and computer hardware is concluded in the last month of a fiscal quarter, generally with a concentration of such revenues earned in the final ten business days of that month. Due to these and other factors, the Company's revenues and operating results are very difficult to forecast. A major portion of the Company's costs and expenses, such as personnel and facilities, are of a fixed nature and, accordingly, a shortfall or decline in quarterly and/or annual revenues typically results in lower profitability or losses. As a result, comparison of the Company's period-to-period financial performance is not necessarily meaningful and should not be relied upon as an indicator of future performance. These forward-looking statements speak only as of the date hereof. The Company undertakes no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise.
