The law firm of Kirby McInerney LLP announces that it has filed a class action lawsuit, Dishion v. Power Solutions International Inc. et al., No. 26 Civ. 3149, in the United States District Court for the Northern District of Illinois on behalf of investors who acquired Power Solutions International Inc. (“Power Solutions” or the “Company”) (NASDAQ:PSIX) securities during the period of May 8, 2025 through March 2, 2026, inclusive (“the Class Period”).
The lawsuit alleges that (1) the Company overstated its ability to capture sales demand for its power systems solutions, particularly within the data center market and (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.”
On November 6, 2025, Power Solutions released its third quarter 2025 financial results, revealing that “gross margin in the third quarter of 2025 was 23.9%, a decrease of 5.0%” year over year due in part to “temporary inefficiencies related to our accelerated production ramp-up” for “key data center product lines.” Further, the Company revealed it “anticipates … sales growth of 45%” for full year 2025, which indicated a sharp deceleration as the Company had reported year-over-year growth of 74% in the second quarter and 65% in the third quarter 2025. On this news, the price of Power Solutions shares declined by $15.55 per share, or approximately 19.1%, from $81.24 per share on November 6, 2025 to close at $65.69 on November 7, 2026.
On March 2, 2026, after the market closed, 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.” On this news, the price of Power Solutions shares declined by $24.84 per share, or approximately 29%, from $85.75 per share on March 2, 2026 to close at $60.91 on March 3, 2026.
