Power Solutions International Business Summary

Power Solutions International, Inc. (PSIX) generates revenue through the design, manufacture, and sale of emission-certified internal combustion engines and fully integrated turnkey power systems. The company operates through three primary business segments: Power Systems, which accounts for approximately 79% of revenue and focuses on stationary and mobile power for data centers and oil and gas applications; Industrial, providing powertrain solutions for material handling and agricultural equipment; and Transportation, serving the vocational truck and school bus markets. PSIX competes directly with global giants such as Cummins Inc., Generac Holdings, and Caterpillar Inc. While significantly smaller in market capitalization, the company has carved out a high-growth niche by specializing in fuel-agnostic, gaseous-fueled engines and rapid-certification power solutions tailored for the surging AI-driven data center infrastructure market. Founded in 1985 by the Winemaster family, PSIX is now majority-owned by Weichai America Corp., a subsidiary of the global industrial conglomerate Weichai Power. The current leadership team is led by CEO and CTO Constantine “Dino” Xykis, a veteran engineer with over 30 years of experience including prior roles at competitors Cummins and Generac. He is supported by CFO Xun (Kenneth) Li, who brings a deep financial pedigree from Caterpillar and Ford Motor Company, and General Counsel Zhaoying (Dorothy) Du, formerly of Lenovo and Motorola Mobility. The Board of Directors is chaired by Jiwen (James) Zhang, who also serves as CEO of Weichai America, reflecting the company's strategic alignment with its primary investor and its focus on leveraging a global supply chain to maintain an asset-light manufacturing model.
