Urgent Notice for Investors of Power Solutions International: Class Action Deadline Approaches

Urgent Notice for Investors of Power Solutions International

In a significant revelation for investors of Power Solutions International, Inc. (NASDAQ: PSIX), the national plaintiffs' law firm Berger Montague PC has announced a class action lawsuit on behalf of shareholders. This legal action aims to address concerns related to securities fraud and is particularly relevant to those who acquired or purchased shares of the company between May 8, 2025, and March 2, 2026. As the deadline approaches on May 19, 2026, it is crucial for affected investors to consider their options and understand their rights.

Power Solutions International operates out of Wood Dale, Illinois, and is known for its manufacturing and supply of power systems, including solutions tailored for data center applications. However, according to the lawsuit, the company allegedly misled investors by making materially false claims about its capability to capture the sales demand for its products, especially within the increasingly competitive data center market.

The lawsuit contends that Power Solutions failed to provide adequate disclosure about the implications of its enhancements in manufacturing capacity needed to meet customer demand. This lack of transparency included critical insights concerning expected costs and the nature of related operational inefficiencies. Investors first received a stark reminder of these troubles on November 6, 2025, when the company reported a significant year-over-year decline in gross margins. This announcement was linked directly to temporary inefficiencies in production related to the ramp-up of essential data center products, ultimately leading to a dramatic drop of approximately 19% in the company’s stock price in just one trading day.

Further complicating the situation, by March 2, 2026, Power Solutions disclosed additional margin deterioration, recognizing that improvements in manufacturing efficiency, as well as supply chain performance, had only just begun. This admission caused the stock price to plummet by another 29%, raising alarm among investors.

Berger Montague is strongly urging all investors who believe they might be affected to take action before the impending deadline. Those wishing to explore their options and potentially serve as lead plaintiff representatives can do so, but must act promptly. This is not merely an invitation but a critical call to protect their rights and interests before the window closes.

For additional information regarding this class action, affected investors are encouraged to contact Berger Montague's attorneys: Andrew Abramowitz at [email protected] or (215) 875-3015, and Caitlin Adorni at [email protected] or (267) 764-4865.
