ACI Worldwide Announces Appointment of Thomas Warsop as President and Chief Executive Officer

ACI Worldwide (NASDAQ: ACIW), a global leader in mission-critical, real-time payments software, today announced that its Board of Directors (the “Board”) has appointed Thomas Warsop as President and Chief Executive Officer, effective June 1, 2023. Warsop, a seasoned executive and financial services technology expert, has served as Interim President and CEO since November 2022. He will also continue to serve on the ACI Board, where he has been a director since 2015. Adalio Sanchez will continue as non-executive Chair of the Board.

“Since joining ACI eight years ago as a member of our Board, and as Interim President and CEO over the last six months, Tom has been instrumental in the refinement and execution of our strategic initiatives,” Sanchez said. “After conducting a thorough search process, and given Tom’s strong management skills, considerable expertise in financial services technology, and deep knowledge of ACI’s business, strategic plan and opportunities to enhance value, the Board is confident he is the right person to continue leading our organization forward.”

Sanchez continued, “ACI is at the epicenter of the digital and real-time payments revolution. Our market-leading software platforms are already used by many of the world’s leading corporations and financial institutions, and we are still in the early stages of this shift. We are confident that under Tom’s steady leadership, ACI is in a strong position to capitalize on the rapid expansion of the global electronic payments market.”

Thomas Warsop said, “It is truly a privilege to continue in the role of CEO of ACI, fully supported by our strong Board and talented and experienced global team. Since assuming the role of Interim CEO in November, I have seen firsthand the depth of our talent and capabilities across the Company. Our teams have made significant progress strengthening ACI’s position in the market, securing and accelerating organic revenue, and expanding our annual recurring revenue. At this time and with our strong foundation in place, we will continue to focus on accelerating growth, optimizing our portfolio, and relentlessly exploring opportunities to enhance value for our shareholders.”

Warsop continued, “While we have more work to do to fully capitalize on the opportunities ahead, we have a strong roadmap and are continuing to execute. We remain on track to achieve our previously stated guidance for revenue growth and adjusted EBITDA, and we will continue to maintain a disciplined approach to capital allocation and portfolio management. I believe we are well-positioned to build on our current momentum as we continue to enable leading corporations, fintechs, financial disruptors and merchants to drive the real-time digital transformation of payments and commerce.”
