Exhibit 99.1 Canadian Solar Reports Third Quarter 2025 Results Kitchener, Ontario, November 13, 2025 – Canadian Solar Inc. (“Canadian Solar” or the “Company”) (NASDAQ: CSIQ) today announced financial results for the third quarter ended September 30, 2025. Third Quarter Highlights · Net revenues of $1.5 billion, at the high end of $1.3 billion to $1.5 billion guidance. · 17.2% gross margin, exceeding guidance of 14% to 16%. · e-STORAGE achieved record 2.7 GWh in quarterly battery energy storage shipments, above guidance of 2.1 GWh to 2.3 GWh. · e-STORAGE’s contracted backlog increased to $3.1 billion, as of October 31, 2025. · Phase I of the solar cell factory in Indiana, U.S. is expected to begin production in March 2026. · Phase I of the lithium battery energy storage factory in Kentucky, U.S. is expected to commence production in December 2026. Dr. Shawn Qu, Chairman and CEO, commented, “Third quarter revenue was at the high end of guidance, while gross margin exceeded expectations, supported by strong energy storage deliveries and a high mix of module shipments to profitable markets. Demand for energy storage continues to grow, driven by emerging applications such as data centers. We are managing the business with discipline, prioritizing profitability and investing strategically to ensure the resilience of our operations. I am pleased to share that our residential energy storage business is on track to become profitable in 2025. At the same time, we are making strong progress on our manufacturing facilities in the U.S. Construction of our solar cell factory in Indiana and our integrated lithium battery cell, pack, and BESS factory in Kentucky is progressing as planned, with production expected to commence in the first and fourth quarters of 2026, respectively.” Yan Zhuang, President of Canadian Solar’s subsidiary CSI Solar, said, “We delivered a sequentially higher share of module shipments to the profitable North American market. Our Mesquite factory, which has now successfully ramped up, contributed meaningfully to both shipment volume and profitability. In our energy storage business, earlier deliveries to two projects shifted certain volumes from the fourth quarter into the third, resulting in a record quarter of 2.7 GWh in shipments. While our $3.1 billion utility-scale storage backlog provides line of sight to future growth, we also continue to develop our offerings and capabilities in C&I and residential storage, segments which we expect will contribute more meaningfully to profitability next year. Looking ahead, we expect further profitability improvements, as we begin production of solar cells and lithium battery energy storage products in the U.S.” Ismael Guerrero, CEO of Canadian Solar’s subsidiary Recurrent Energy, said, “Profitability improved sequentially, driven by higher margin contributions from this quarter’s project sales. These included the profitable sales of an energy storage project in Italy and a hybrid project in Australia. Until our IPP business scales further—expanding electricity sales and power services as recurring revenue streams— near-term profitability will continue to depend primarily on global project sales. Maintaining financial discipline remains our top priority. We will balance the growth of our operating portfolio and selective project ownership sales to prudently manage cash flow and debt levels. Looking ahead to 2026, we expect to tip this balance more toward project ownership sales to enhance cash recycling and reduce leverage.” Xinbo Zhu, Senior VP and CFO, added, “In the third quarter, we achieved revenue of $1.5 billion, at the high end of guidance, and delivered a gross margin of 17.2%, exceeding expectations. Operating expenses normalized with the absence of one-time items, resulting in net income attributable to shareholders of $9 million. With continued discipline in working capital management and prudent pacing of project construction, we ended the quarter with a cash position of $2.2 billion.” Third Quarter 2025 Results Total module shipments recognized as revenues in Q3 2025 were 5.1 GW, down 35% quarter-over-quarter (“qoq”) and down 39% year- over-year (“yoy”). Of the total, 33 MW were shipped to the Company’s own utility-scale solar power projects. Page 1
Page 2
Net revenues were $1.5 billion in Q3 2025, down 12% sequentially and 1% yoy, mainly due to lower sales of solar modules partially offset by higher sales of battery energy storage systems. Gross profit was $256 million, compared to $505 million in Q2 2025 and $247 million in Q3 2024. Gross margin was 17.2%, compared to 29.8% and 16.4%, respectively. The sequential decrease in gross margin was primarily due to the absence of a release of profit upon sales- type leasing of a U.S. project in Q2. The yoy increase was driven by a higher contribution from battery energy storage systems, which have delivered a more favorable margin profile than solar modules on a blended basis. Operating expenses were $222 million, down from $378 million in Q2 2025 and $247 million in Q3 2024 due to ongoing cost reductions and absence of impairment charges related to certain solar and storage assets, as well as manufacturing assets. Operating expenses represented 14.9% of revenue, compared to 22.3% in Q2 2025 and 16.4% in Q3 2024. Net income attributable to Canadian Solar in accordance with generally accepted accounting principles in the United States of America (“GAAP”) in Q3 2025 was $9 million, or a net loss of $0.07 per diluted share, compared to a net income of $7 million, or a net loss of $0.08 per diluted share, in the Q2 2025, and net loss of $14 million, or $0.31 per diluted share, in Q3 2024. Net loss per diluted share includes the dilutive effect of convertible bonds and Recurrent Energy redeemable preferred shares dividends, as applicable. Adjusted net loss attributable to Canadian Solar Inc. (non-GAAP) was $26 million, and adjusted loss per share - diluted was $0.58 per share in Q3 2025, compared to an adjusted net loss of $23 million and adjusted loss per share - diluted of $0.53 per share in Q2 2025, and a net loss of $14 million or $0.31 per share in Q3 2024. Adjusted net loss attributable to Canadian Solar Inc. and adjusted loss per share - diluted in Q3 2025 and Q2 2025 exclude the recognition of income using hypothetical liquidation at book value (“HLBV”) method. The Company uses the HLBV method to attribute income and loss to its tax equity investors. Please see Recurrent Energy - HLBV for definition and About Non-GAAP Financial Measures for reconciliation to nearest GAAP measures. Net cash flow used in operating activities in Q3 2025 was $112 million, driven by changes in working capital, specifically a decrease in inventories during the prior quarter, compared to net cash flow provided by operating activities of $189 million in Q2 2025 and net cash flow used in operating activities of $231 million in Q3 2024. Total debt, including financing liabilities, was $6.4 billion as of September 30, 2025, including $2.7 billion, $3.5 billion, and $0.2 billion related to CSI Solar, Recurrent Energy, and convertible notes, respectively. Total debt rose from $6.3 billion as of June 30, 2025, mainly due to new borrowings for development of projects and operational assets. Total non-recourse debt as of September 30, 2025, was $2.0 billion. Business Segments The Company operates in two reportable segments: CSI Solar, focused on solar modules and battery energy storage manufacturing and products, and Recurrent Energy, focused on utility-scale solar power and battery energy storage project development and operation. Recurrent Energy As of September 30, 2025, the Company held a leading position with a total global solar project development pipeline of approximately 25 GWp and a battery energy storage project development pipeline of 81 GWh. The business model consists of three key drivers: · Electricity revenue from operating portfolio to drive stable, diversified cash flows in growth markets with stable currencies, with some project ownership sales to manage cash flow and debt level; · Asset sales (solar power and battery energy storage) in the rest of the world to drive cash-efficient growth model, as value from project sales will help fund growth in operating assets in stable currency markets; and · Power services (O&M) through long-term operations and maintenance (“O&M”) contracts, currently with over 14 GW of contracted projects, to drive stable and long-term recurring earnings and synergies with the project development platform.

Project Development Pipeline – Solar As of September 30, 2025, the Company’s total solar project development pipeline was 25.1 GWp, including 2.0 GWp under construction, 3.4 GWp of backlog, and 19.7 GWp of projects in advanced and early-stage development, defined as follows: · Backlog projects are late-stage projects that have passed their risk cliff date and are expected to start construction in the next 1-4 years. A project’s risk cliff date is the date on which the project passes the last high-risk development stage and varies depending on the country where it is located. Typically, this occurs after the project has received all the required environmental and regulatory approvals, and entered into interconnection agreements and offtake contracts, including feed-in tariff (“FIT”) arrangements and power purchase agreements (“PPAs”). A significant majority of backlog projects are contracted (i.e., have secured a PPA or FIT), and the remaining have a reasonable assurance of securing PPAs. · Advanced pipeline projects are mid-stage projects that have secured or have more than 90% certainty of securing an interconnection agreement. · Early-stage pipeline projects are early-stage projects controlled by the Company that are in the process of securing interconnection. While the magnitude of the Company’s project development pipeline is an important indicator of potential expanded power generation and battery energy storage capacity as well as potential future revenue growth, the development of projects in its pipeline is inherently uncertain. If the Company does not successfully complete the pipeline projects in a timely manner, it may not realize the anticipated benefits of the projects to the extent anticipated, which could adversely affect its business, financial condition, or results of operations. In addition, the Company’s guidance and estimates for its future operating and financial results assume the completion of certain solar projects and battery energy storage projects that are in its pipeline. If the Company is unable to execute on its actionable pipeline, it may miss its guidance, which could adversely affect the market price of its common shares and its business, financial condition, or results of operations. HLBV The Company applies the HLBV method to account for its contractual relationships with tax equity investors in U.S. solar energy and battery energy storage projects. This method which allocates income or loss attributable to redeemable noncontrolling interests reflects the changes in the amounts that tax equity investors would hypothetically receive upon liquidation at the beginning and end of each reporting period, after considering any capital transactions, such as contributions or distributions, between the subsidiaries and tax equity investors. The following table presents the Company’s total solar project development pipeline.

About Non-GAAP Financial Measures This press release also contains adjusted net income (loss) attributable to Canadian Solar Inc. and adjusted earnings (loss) per share - diluted that are not determined in accordance with GAAP. These non-GAAP financial measures should not be considered as an alternative to net income (loss) attributable to Canadian Solar Inc. or earnings (loss) per share, respectively, each of which is an indicator of financial performance determined in accordance with GAAP. Adjusted net income (loss) attributable to Canadian Solar Inc. and adjusted earnings (loss) per share - diluted exclude from net income (loss) attributable to Canadian Solar Inc. and earnings (loss) per share certain items that the Company does not consider indicative of its ongoing financial performance such as the effects of HLBV method to account for its tax equity arrangements. Management uses these non-GAAP financial measures to facilitate the analysis and communication of the Company’s financial performance as compared to its previous financial results. Management believes that these non-GAAP financial measures are also useful and meaningful to investors to facilitate their analysis of the Company’s financial performance. These non-GAAP measures may differ from non-GAAP measures used by other companies, and therefore their comparability may be limited. The table below provides a reconciliation of our GAAP net income (loss) to non-GAAP financial measures.
