On November 6, 2025, Power Solutions International, Inc. 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 March 2, 2026, after the market closed, Power Solutions International, Inc. announced its 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."

(NASDAQ: PSIX) common shares between May 8, 2025 through March 2, 2026, that the defendants violated Federal Securities Laws.
