Fiserv Clover Class Action: Fraud Claims, CEO Exit, SEC Probe

The Fiserv Clover class action lawsuit is a securities fraud case filed in July 2025 by a Florida municipal pension fund, alleging that Fiserv, Inc. misled investors by claiming its Clover point-of-sale platform was growing on the strength of new merchants when, according to the complaint, roughly half of Clover’s revenue growth actually came from forcing about 200,000 existing merchants off a legacy system called Payeezy and onto the more expensive Clover platform. The case is City of Hollywood Police Officers’ Retirement System v. Fiserv, Inc., No. 1:25-cv-06094, in the U.S. District Court for the Southern District of New York.¹

The proposed class covers investors who purchased or held Fiserv stock (NYSE: FI) between July 24, 2024, and July 22, 2025. Named defendants are Fiserv and four officers: former CEO Frank J. Bisignano, current CEO Michael P. Lyons, CFO Robert W. Hau, and chief accounting officer Kenneth F. Best.¹²

What Fiserv Is Accused of Doing

The allegations center on a platform swap. Fiserv had long operated Payeezy, a payment gateway used by small and mid-sized merchants. Starting in late 2023, the company began winding Payeezy down and moving those merchants onto Clover, a pricier point-of-sale system with more hardware and software features. The complaint alleges that as many as 200,000 merchant locations were forcibly migrated between late 2023 and the first half of 2024.³

For 2024, Fiserv reported Clover revenue of $2.7 billion on $310 billion in gross payment volume, with 29% revenue growth.⁴ Executives told investors that about 90% of Clover’s growth came from new, organic merchant sign-ups and only about 10% from converting existing customers. The complaint alleges those statements were false, and that the forced Payeezy migrations were the real engine behind the numbers, accounting for roughly half of Clover’s year-over-year revenue growth.

The suit further alleges the strategy backfired. Many of the migrated Payeezy merchants were price-sensitive small businesses that did not need Clover’s added features. Facing higher costs and, according to the complaint, poor customer service and compatibility problems, those merchants left Clover “en masse” for competitors such as Block’s Square, Toast, and Shopify.⁵ The churn allegedly hollowed out transaction volumes even as revenue held up on higher per-merchant pricing. By the first quarter of 2025, Clover’s annualized gross payment volume growth had fallen to 8%, down from 14% in the fourth quarter of 2024, while revenue growth stayed at 27%.

How the Story Reached Investors

The complaint identifies three disclosures in 2025 that it says gradually revealed the truth about Clover, each followed by a sharp drop in Fiserv shares.

On April 24, 2025, Fiserv reported first-quarter results showing Clover volume growth of just 8% and a 9% decline in payments processing revenue within its Merchant Solutions segment. The company blamed weaker consumer spending and lower transaction volumes from converted Payeezy merchants. Shares fell about 18.5% that day.⁶

On May 15, 2025, at a JPMorgan investor event, CFO Robert Hau said second-quarter Clover volume growth would be “generally similar” to the 8% reported in Q1. He acknowledged the tailwind from converting Payeezy clients to Clover “doesn’t repeat this year” and would become a “headwind.” Shares dropped more than 16%.⁷

On July 23, 2025, Fiserv released second-quarter results and lowered the top end of its full-year organic revenue growth guidance to about 10%, down from a prior range of 10% to 12%. The stock fell roughly 14%.⁸

The losses compounded in October 2025, when new CEO Mike Lyons withdrew earlier earnings forecasts set under Bisignano, calling them “objectively difficult to achieve.” By then, the stock had fallen nearly 50% from its highs.⁹

Bisignano’s Departure and the Insider-Trading Allegations

Frank Bisignano led Fiserv from 2020 until May 2025, when he resigned to become Commissioner of the Social Security Administration after being nominated by President-elect Donald Trump in December 2024 and confirmed by the Senate. Between May and August 2025, Bisignano and his family sold their Fiserv holdings for approximately $560 million, before the steepest declines in October.¹⁰

His representatives have said the sales were required divestitures under federal ethics rules for entering government service. Representatives John Larson and Jim Himes asked the SEC to investigate whether Bisignano knew about Fiserv’s deteriorating position and used the government-mandated divestiture window to avoid personal losses.⁹ A shareholder derivative complaint filed in December 2025 accused Bisignano and another officer of selling at artificially inflated prices and alleged total insider proceeds exceeding $600 million.¹¹

Related Cases and Federal Investigations

The New York suit is no longer the only proceeding. In November 2025, separate securities fraud complaints were filed in the U.S. District Court for the Eastern District of Wisconsin under case number 25-cv-1716, naming Fiserv, Lyons, and Hau. Those cases cover a later class period, July 23 to October 29, 2025, and focus on whether management’s second-quarter 2025 guidance was itself false and misleading. They were consolidated on February 5, 2026.¹²

Between December 2025 and February 2026, three shareholder derivative suits were filed in the Eastern District of Wisconsin, naming Bisignano, Lyons, and other current and former officers and directors, alleging breaches of fiduciary duty and illegal insider trading. They have been consolidated as In re: Fiserv, Inc. Shareholder Derivative Litigation. On June 3, 2026, a federal judge ordered all proceedings stayed indefinitely, pending the outcome of the New York securities class actions.¹³

In November 2025, Fiserv also began responding to information requests from the Enforcement Division of the Securities and Exchange Commission and the U.S. Attorney’s Office for the Southern District of New York. Both inquiries focus on the company’s 2025 earnings guidance. Fiserv has said it is cooperating and has not disclosed further details about scope or progress.¹²

Where the Case Stands

Lead plaintiffs in the New York action were appointed on November 17, 2025. Under a stipulation filed in August 2025, the parties agreed to a schedule for an amended complaint and a defense response, but as of Fiserv’s most recent SEC filing covering the period through December 2025, defendants had not yet answered or otherwise responded to any of the pending complaints. No class has been certified, and no trial date has been set.¹²¹

Fiserv has maintained a $25 million accrual for legal proceedings, with estimated additional exposure of up to $160 million. The company has said it “disagrees with the claims and will vigorously defend itself.”¹²³ Motions practice, discovery, and any settlement discussions remain ahead.
