(PSI) reported significant financial growth for the fiscal year ending December 31, 2025, with net sales reaching $722.4 million, a 52% increase from $476.0 million in 2024. The company’s net income also rose to $114.0 million, up 65% from $69.3 million the previous year. This growth was primarily driven by a substantial increase in the power systems market, which accounted for 81% of total sales, reflecting a strategic shift towards higher-margin sectors such as data centers and oil and gas.
In terms of operational changes, PSI sold approximately 19,800 engines in 2025, with 74% utilizing propane or natural gas as fuel sources. The company has also focused on enhancing its manufacturing capacity to meet the growing demand in the data center market. Additionally, PSI entered into a strategic collaboration with Weichai, which has been extended through March 2026, allowing the company to leverage Weichai's strengths in research and development, manufacturing, and distribution.
The company has made notable changes in its organizational structure, including the appointment of Zhaoying (Dorothy) Du as General Counsel and Corporate Secretary in September 2025. PSI's workforce consisted of approximately 1,000 full-time employees as of December 31, 2025, with a turnover rate of 18%. The company is also actively managing its warranty expenses, which have been a focus area for cost mitigation.
Looking ahead, PSI is navigating a complex macroeconomic environment, including the impact of geopolitical tensions and fluctuating oil and gas prices. The company has amended its Revolving Credit Agreement, increasing its borrowing capacity to $135 million and extending the maturity date to July 30, 2027. However, PSI has opted not to provide specific guidance for 2026, citing ongoing uncertainties in customer order timing and broader market conditions. The company remains committed to optimizing its cost structure while pursuing growth opportunities in high-demand markets.
