OMAHA, Neb. / October 1, 2025—ACI Worldwide (NASDAQ: ACIW), an original innovator in global payments technology, today announced that Todd Ford and Didier Lamouche have been appointed as independent directors to its Board of Directors (the "Board"). These appointments reflect the Board's ongoing commitment to adding highly qualified business leaders to the ACI Board.

Mr. Ford most recently served as President, CFO and EVP Operations at Coupa, the leading SaaS platform for business spend management.

Mr. Lamouche most recently served as President and CEO of IDEMIA (formerly Oberthur Technologies). In addition to his previous Board experience at ACI, he brings extensive global technology company leadership experience and a deep insight into the international technology market.

"We look forward to benefitting from the addition of Todd and Didier to our Board," said Adalio Sanchez, Chair of the Board of ACI. "Board refreshment continues to be a top priority as we plan for the expected retirement and transition of two current directors. We are confident that Todd and Didier will each bring important skills and expertise to our boardroom. Todd is an accomplished executive with broad financial, operational, and M&A experience in the technology sector, with specific expertise in SaaS software companies. Didier has decades of experience as CEO of various global technology companies and particularly in managing them through evolving market conditions. He also knows our company well from his previous stint on the ACI Board."

"Todd's many years as CFO of high-growth software technology companies in combination with Didier's successful track record as CEO of leading global systems technology companies will add value to our Board and management team as we focus on accelerating our sustainable growth, delivering industry-leading software solutions and generating shareholder value," said Thomas Warsop, President and CEO of ACI.
