NASDAQ: PSIX CLASS ACTION NOTICE: Berger Montague Encourages Power Solutions International, Inc. (NASDAQ: PSIX) Investors to Inquire About a Securities Fraud Class Action

PHILADELPHIA, May 4, 2026 /PRNewswire/ -- National plaintiffs' law firm Berger Montague PC announces a class action lawsuit against Power Solutions International, Inc. (NASDAQ: PSIX) ("Power Solutions" or the "Company") on behalf of investors who purchased or acquired Power Solutions shares during the period from May 8, 2025 through March 2, 2026 (the "Class Period").

Investor Deadline: Investors who purchased or acquired Power Solutions securities during the Class Period may, no later than May 19, 2026, seek to be appointed as a lead plaintiff representative of the class. To learn your rights, CLICK HERE.

The Company, headquartered in Wood Dale, Illinois, manufactures and supplies power systems, including solutions designed for data center applications.

According to the complaint, Power Solutions made materially false and misleading statements regarding its ability to capture sales demand for its power systems solutions, particularly within the data center market, and failed to adequately disclose the impact of its enhancements to manufacturing capacity to meet that demand, including the expected costs and the nature of the related inefficiencies.

Investors began to learn the truth on November 6, 2025, when Power Solutions disclosed a year-over-year gross margin decline and attributed the drop in part to temporary inefficiencies related to its production ramp-up for key data center product lines. Following this announcement, the Company's stock price declined approximately 19% in a single trading day.

On March 2, 2026, Power Solutions reported further margin deterioration and acknowledged that improvements in manufacturing efficiency and supply chain performance were only beginning to materialize. On this news, the Company's share price fell approximately 29%.
