Robbins LLP has filed a class action lawsuit on behalf of investors who purchased Power Solutions International, Inc. (NASDAQ: PSIX) securities between May 8, 2025 and March 2, 2026. The complaint alleges that the company misled investors about its ability to meet demand and the costs associated with ramping up production for its data center power systems.

Why it matters

The lawsuit alleges that Power Solutions International failed to disclose issues with its manufacturing capacity and costs, leading to a significant stock price drop when the problems were revealed. This highlights the importance of transparency for public companies and the potential legal recourse available to shareholders who suffer losses due to alleged corporate misconduct.

The details

According to the complaint, during the class period, Power Solutions International overstated its ability to capture sales demand for its data center power systems and understated the impact and costs of enhancing its manufacturing capacity to meet that demand. On March 2, 2026, the company reported a decline in gross margin due to 'operating inefficiencies related to [the Company's] accelerated production ramp-up for data center product lines' and only 'moderate margin improvement' expected in 2026. This led to a 28.97% drop in the company's stock price on March 3, 2026.

  • The class period is from May 8, 2025 to March 2, 2026.
  • The lawsuit was filed on April 16, 2026.
  • Shareholders have until May 19, 2026 to file to serve as lead plaintiff in the class action.
