Potential Concerns Under Investigation

Attorneys are reviewing whether Power Solutions International and certain executives made false or misleading statements or failed to disclose material information between May 2025 and November 6, 2025.

During this period, the company repeatedly emphasized record performance and sustained demand. On May 8, 2025, management described the first quarter as “the best first-quarter performance in the Company’s history,” citing 42% year-over-year sales growth.

On August 7, 2025, Power Solutions again reported “the strongest sales and profit performance” with 74% year-over-year sales growth, asserting that momentum remained strong. The company’s SEC filings stated that management “expects this positive trend to continue.”

However, those statements were called into question on November 6, 2025, when Power Solutions released third-quarter results. Although the company reported 62% year-over-year sales growth, it issued full-year guidance of only about 45%, signaling a sharp deceleration relative to prior quarters.

Following this announcement, Power Solutions International’s stock fell $15.55 per share, or roughly 19%, closing at $65.69 on November 7, 2025, resulting in substantial losses for investors.
