The Allegations: Robbins LLP is Investigating Allegations that Power Solutions International, Inc. (PSIX) Misled Investors Regarding its Business Prospects

According to the complaint, during the class period, defendants failed to disclose to investors: (1) the Company overstated its ability to capture sales demand for its power systems solutions, particularly within the data center market; (2) the Company understated the impact of its enhancements to manufacturing capacity to meet demand within the data center market, including the expected costs and the nature of the related “inefficiencies”; and (3) that, as a result of the foregoing, defendants’ positive statements about the Company’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis.

Plaintiff alleges that on March 2, 2026, Power Solutions issued a press release announcing fourth quarter and full year 2025 financial results, revealing that gross margin declined 8% year-over-year due to “operating inefficiencies related to [the Company’s] accelerated production ramp-up for data center product lines.” Further, the Company provided its outlook for 2026, including only “moderate margin improvement from the products serving data center markets.” The press release also revealed the Company was “executing specific actions to improve supply chain performance and manufacturing cost structures” but only now “beginning to see measurable improvements, which [it] expect to build and support margin expansion over time.” Following these disclosures, Power Solutions stock fell $24.84 or 28.97% to close at $60.91 on March 3, 2026.
