Fiserv, Inc. faces a legal investigation by Ademi LLP regarding potential breaches of fiduciary duty by its Board of Directors following the sudden resignation of Chief Executive Officer Michael P. Lyons. The Wisconsin-based law firm announced on June 15, 2026, that it is examining whether the board failed to act in the best interests of shareholders during the leadership transition. This scrutiny comes after Fiserv shares fell nearly 8% on the news of the CEO's departure, despite the company reaffirming its financial guidance for FY26.
Ademi LLP specializes in securities fraud and shareholder litigation. The firm is inviting affected shareholders to join the investigation or obtain additional information. The focus of the inquiry is the immediate resignation of Mr. Lyons and the subsequent appointment of Takis Georgakopoulos as the new CEO and Board member.

He previously served as Co-President leading Technology and Merchant Solutions and was the Global Head of Payments for J.P. Morgan's Corporate and Investment Bank.
Gordon Nixon, Chairman of the Fiserv Board of Directors, expressed confidence in the new leadership.
