Berger Montague PC Alerts Fiserv Investors of Class Action

On December 15, 2025, Berger Montague, a prominent national law firm, announced the filing of a class action lawsuit against Fiserv, Inc., a leading provider of payment and financial technology solutions. This action represents investors who purchased Fiserv shares during the class period from July 23, 2025, to October 29, 2025.

Background of the Lawsuit

The lawsuit stems from alleged misleading statements made by Fiserv regarding its financial guidance. According to the complaint, the firm had revised its 2025 financial forecasts in July 2025 after a reassessment of its initiatives. The management of Fiserv reassured investors that despite encountering project delays, the fundamentals remained intact and strong. However, these assurances were significantly challenged on October 29, 2025, when Fiserv disclosed that its previous guidance was based on overly optimistic assumptions that were unlikely to materialize even with the right investments and execution.

This revelation led to a dramatic fall in Fiserv’s stock price, which decreased by 44%, plummeting from a closing price of $126.17 per share on October 28 to just $70.60 the following day. The sharp decline in share price raised concerns among investors regarding the accuracy of Fiserv’s prior statements and the overall transparency of the company’s financial reporting process.

Important Deadlines for Investors

As part of this legal action, investors who acquired Fiserv securities during the defined class period should be aware that they have until January 5, 2026, to act. Specifically, they may seek to be appointed as lead plaintiffs in this matter, which allows them to take a more active role in the litigation process. It is crucial for affected investors to understand their rights and potential avenues for recovery in this scenario.
