(NASDAQ: PSIX) (“Power Solutions” or the “Company”) on behalf of investors who purchased or acquired Power Solutions shares during the period from May 8, 2025 through March 2, 2026 (the “Class Period”).

The lawsuit alleges the Company overstated its ability to capture sales demand for its power systems solutions, particularly within the data center market, while failing to disclose the impact of its enhancements to manufacturing capacity to meet that demand, including the expected costs and the nature of the related inefficiencies.
The true state of the Company’s finances began to be revealed on November 6, 2025, when the Company reported third quarter 2025 financial results revealing that gross margin was 23.9%, a decrease of 5.0% year-over-year, due in part to temporary inefficiencies related to its accelerated production ramp-up for key data center product lines. The Company also disclosed that it anticipated full-year 2025 sales growth of 45%, representing a sharp deceleration from 74% growth in the second quarter and 65% growth in the third quarter of 2025.
On this news, Power Solutions’ stock price declined $15.55 per share, or approximately 19.1%, from $81.24 per share on November 6, 2025 to close at $65.69 per share on November 7, 2025.
Subsequently, on March 2, 2026, Power Solutions reported fourth quarter and full year 2025 results, revealing that gross margin declined 8% year-over-year due to operating inefficiencies related to its production ramp-up for data center product lines. The Company also provided its 2026 outlook, indicating only moderate margin improvement.
On this news, the Company’s share price declined $24.84 per share, or approximately 29%, from $85.75 per share on March 2, 2026 to close at $60.91 per share on March 3, 2026.
