Welcome to our dedicated page for Canadian Solar SEC filings (Ticker: CSIQ), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
Canadian Solar Inc. filings document a foreign private issuer in solar technology, battery energy storage and renewable project development. Its Form 20-F annual reports and Form 6-K current reports cover operating results, segment activity, risk factors, governance, capital structure and material events tied to its Manufacturing and Recurrent Energy businesses.
The filing record includes reports on CSI Solar Co., Ltd., Canadian Solar's majority-owned subsidiary listed on the Shanghai Stock Exchange's Sci-Tech Innovation Board, including translated quarterly, preliminary and earnings forecast disclosures. Other 6-K reports document financial results, shareholder voting matters, material agreements and capital actions such as convertible senior notes, along with disclosures related to U.S. manufacturing capacity and the solar and battery storage value chain.
Canadian Solar Inc. reported first quarter 2026 revenue of $1.1 billion, as lower solar module sales were partly offset by stronger battery storage demand. Solar module shipments recognized as revenue were 2.5 GW, sharply lower quarter-over-quarter, while battery energy storage shipments rose to 2.1 GWh.
Gross profit increased to $271 million and gross margin to 25.1%, helped by a one-time $93 million tariff refund. Net loss attributable to shareholders narrowed to $32 million, or $0.71 per share, and cash ended at $1.9 billion with total debt of $6.8 billion. The company guided Q2 2026 revenue of $1.0–$1.2 billion, gross margin of 13–15%, module shipments of 3.1–3.3 GW and storage shipments of 2.8–3.2 GWh, and announced Colin Parkin as the new CEO as founder Dr. Shawn Qu becomes Executive Chairman and CTO.
Canadian Solar Inc. filed a Form 6-K furnishing Q1 2026 results for its majority-owned subsidiary CSI Solar Co., Ltd. CSI Solar reported operating revenue of RMB7.13 billion, down from RMB8.59 billion a year earlier, reflecting softer top-line demand.
Despite lower revenue, net profit attributable to shareholders jumped to RMB519 million from RMB47 million, driven mainly by recognition of refundable tariffs under the International Emergency Economic Powers Act (IEEPA) after recent U.S. court rulings. Net profit excluding non-recurring items rose to RMB344 million.
Operating cash flow swung to an outflow of RMB157 million from an inflow of RMB1.39 billion as some sales proceeds were not yet collected. Total assets were RMB63.08 billion and equity attributable to shareholders was RMB23.64 billion. The figures are unaudited and prepared under PRC GAAP, which differs materially from Canadian Solar’s U.S. GAAP reporting.
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.

Parkin Colin reported acquisition or exercise transactions in this Form 4 filing.
Canadian Solar Inc. director Colin Parkin received a grant of 28,542 Restricted Share Units linked to common stock. These RSUs were awarded at no cash cost and represent equity-based compensation rather than an open-market share purchase or sale. Following the grant, Parkin holds 28,542 RSUs directly. According to the terms, the RSUs will vest in four approximately equal annual installments beginning on December 23, 2026, meaning the economic benefit is spread over several years and depends on continued service and future vesting.

After these transactions, he directly holds 45,682 shares of common stock and 22,968 RSUs, indicating a largely unchanged overall exposure to Canadian Solar stock.
