What Is This Lawsuit About? The lawsuit alleges that Fiserv made misleading statements and omissions regarding the Company’s initiatives and projects.

On October 29, 2025, Fiserv revealed that the Company’s 2025 guidance disclosed in July 2025 was based on “assumptions . . . which would have been objectively difficult to achieve even with the right investment and strong execution.” On this news, the price of Fiserv shares declined by $55.57 per share, or approximately 44%, from $126.17 per share on October 28, 2025 to close at $70.60 on October 29, 2025.

The Lead Plaintiff Appointment Process. The federal securities laws permit any investor who acquired eligible securities during the class period to seek appointment as lead plaintiff in a class action lawsuit. Courts typically appoint the investor(s) with the largest financial loss in the case and the ability to represent the class rather than investors with simply the largest investment portfolio. Courts regularly appoint individual investors, whether acting alone or as a group, as lead plaintiffs. The rights of any investor who bought shares during the class period are generally already protected. However, lead plaintiffs have the power to influence case strategy and have a say in settlement decisions, as well as decisions concerning allocation of settlement funds among class members.
