Canadian Solar Inc. files its annual Form 20-F, outlining a global business now organized into two main segments: Manufacturing (CSI Solar plus new U.S.-focused CS PowerTech) and Recurrent Energy (project development, asset sales and power services).
The company highlights a strategic shift toward the United States, where 19.5%, 46.3% and 49.6% of consolidated revenue came from the U.S. in 2023, 2024 and 2025, while China’s share declined over the same period. Long‑lived assets are also tilting toward the U.S. as capital is deployed into new module, cell and storage factories in Texas, Indiana and Kentucky.
The filing details extensive risk factors, including volatility in solar and storage markets, supply chain and pricing pressure, project execution and offtake risks, heavy use of debt, and complex global trade and tariff regimes. It also emphasizes legal and operational risks tied to CSI Solar’s large manufacturing base in China, HFCAA-related audit oversight history, evolving U.S. clean energy tax rules under the IRA and OBBBA, and broad ESG and climate-disclosure requirements emerging in the U.S., Europe and China.
