Power Solutions International is facing a federal securities lawsuit alleging investors were misled about demand for its power systems and the costs of ramping up manufacturing of data center products. The complaint says the stock fell 19.14% on November 7, 2025, and 28.97% on March 3, 2026, following disclosures tied to gross margin pressure and slower-than-expected sales growth for 2025 and 2026.
Investors who bought PSIX during the alleged class period of May 8, 2025, through March 2, 2026, may want to review the complaint to see whether they were affected.
Company Background
According to the complaint, Power Solutions designs, manufactures, and sells engines and power systems, including small engines for use in industrial equipment and transit vehicles, as well as micro-power systems. The filing says the company shifted attention toward the data center market in 2025 as its transportation end market declined. It also says the company described that shift as part of a focus on higher-growth, higher-margin business.
Core Allegations
The lawsuit centers on the company’s statements about demand for its power systems, especially in the data center market, and the effects of expanding manufacturing capacity to meet that demand. The complaint alleges that Power Solutions overstated its ability to capture demand, understated the costs and operational impact of the ramp-up, and made positive statements that were not reasonably based. In plain English, the case says investors were told the data center push was boosting growth and margins, while the company later disclosed margin pressure tied to production inefficiencies.
Readers who bought PSIX during the period may want to follow the case closely and assess whether they fall within the alleged affected group.
Management Statements
The complaint quotes CEO Dino Xykis as saying, after first-quarter results, that the company’s performance reflected “the growing demand for our solutions, particularly in power systems,” and that it was focused on “improving and increasing our manufacturing capacity and capabilities” to meet demand in data centers. For second-quarter results, he said the company’s results reflected “strong demand for our power systems solutions” and described the data center sector as a key growth focus. For third-quarter results, he said the company had expanded manufacturing capacity and was increasing production across key data center product lines.
The filing also cites the company’s investor presentation, which said the “increase mix of Power Systems business” offered “superior margins,” and that gross margin declines were due to “temporary inefficiencies related to our accelerated production ramp-up”. In the fourth-quarter release, Xykis said the company was seeing “continued demand” in data centers and was taking actions to improve supply chain performance and manufacturing cost structures.
Corrective Disclosures
On November 6, 2025, Power Solutions reported third-quarter results and said gross margin was 23.9%, down 5.0% year over year, due in part to “temporary inefficiencies related to our accelerated production ramp-up” for key data center product lines. The complaint says the company also projected 45% sales growth for full-year 2025, below the growth rates it had reported earlier in the year. The filing says the stock fell $15.55, or 19.14%, to $65.69 on November 7, 2025, on unusually heavy volume.
On March 2, 2026, Power Solutions released fourth-quarter and full-year 2025 results and said gross margin declined 8% year over year because of “operating inefficiencies related to [its] accelerated production ramp-up for data center product lines”. It also said it expected only “moderate margin improvement” from products serving data center markets and was only beginning to see measurable improvements in its supply chain and manufacturing cost structure actions. The complaint says the stock dropped $24.84, or 28.97%, to $60.91 on March 3, 2026, again on unusually heavy volume.
Why It Matters
For investors, the alleged issue is whether the company’s upbeat statements about its data center strategy and margin outlook aligned with the operational reality it later disclosed. The complaint says the stock declines followed disclosures about margin pressure, production inefficiencies, and a slower growth outlook. Shareholders who bought during the alleged class period may view the case as relevant because it links the claimed misstatements to the price declines.
Legal Claims
The complaint says the defendants violated Section 10(b) of the Securities Exchange Act and Rule 10b-5, and that the individual defendants are also liable under Section 20(a) as controlling persons. It alleges that statements about demand, margins, and manufacturing expansion were false or misleading because they omitted material facts about the company’s ability to meet data center demand and the cost and impact of the ramp-up. The suit seeks damages for investors who purchased Power Solutions securities during the alleged class period.
Investors who believe they were affected may want to review their rights in light of the allegations in the complaint.
