Canadian Solar Reports Fourth Quarter and Full Year 2024 Results

Kitchener, Ontario, March 25, 2025 – Canadian Solar Inc. (“Canadian Solar” or the “Company”) (NASDAQ: CSIQ) today announced financial results for the fourth quarter and full year ended December 31, 2024.

Fourth Quarter Highlights

Full Year 2024 Highlights

Dr. Shawn Qu, Chairman and CEO, commented, “2024 was a challenging year for the solar industry, with intense competition and ongoing policy and trade-related uncertainties creating operational and financial headwinds. Despite these industry-wide pressures, our modules business executed targeted strategic adjustments, enabling us to maintain relatively stronger profitability compared to the broader market. The industry and Canadian Solar are undergoing a transition. While near- to mid-term uncertainties persist in the solar market, demand for energy storage is accelerating. Storage is increasingly compelling, both in stand-alone applications and when paired with solar, driven by growing energy demand from sectors such as data centers and electric vehicles. Finally, we remain fully committed to the U.S. market and continue to advance our manufacturing expansion across three facilities dedicated to solar modules, solar cells, and energy storage solutions.”

Yan Zhuang, President of Canadian Solar’s subsidiary CSI Solar, said, “Our team at CSI Solar remained focused while navigating a turbulent 2024. By maintaining a disciplined order-taking strategy, we were able to sustain relatively competitive pricing while continuing to improve cost efficiencies across our vertically integrated supply chain and tightly managing operating expenses. Energy storage was a key profitability driver, as we delivered both quarterly and full year shipment records. While we anticipate margin normalization in this segment, our priority remains scaling volume and further diversifying our global footprint. With our largest-ever pipeline and a robust contracted backlog, we have strong visibility into future growth.”

Ismael Guerrero, CEO of Canadian Solar’s subsidiary Recurrent Energy, said, “We made significant progress in our business model transformation in 2024, starting construction on 1.4 GWp of solar PV and 1.4 GWh of energy storage projects. Of these, 420 MWp of PV reached commercial operation in the U.S. across Texas, Oklahoma, and Louisiana. That said, project sales delays in 2024 impacted our full year performance. As we bring more projects to commercial operation, our recurring income will continue to scale.”

Xinbo Zhu, Senior VP and CFO, added, “In the fourth quarter, we generated $1.5 billion in revenue with a gross margin of 14.3%. Profitability was impacted by a combination of impairments to Recurrent Energy projects, impairments to certain solar manufacturing assets, anti-dumping/countervailing duties, and tariffs. Net income attributable to shareholders of $34 million and earnings per diluted share of $0.48 were positively impacted by HLBV method of accounting relating to tax equity arrangements of U.S. projects, totaling $132 million or $1.95 per share, respectively. Capital expenditures came in slightly below expectations, totaling $1.1 billion in 2024. We ended the year with $2.3 billion in cash, ensuring we have the financial flexibility to support working capital needs and make strategic investments in the year ahead.”

Fourth Quarter 2024 Results

Total module shipments recognized as revenues in the fourth quarter of 2024 were 8.2 GW, down 2% quarter-over-quarter (“qoq”) and up 1% year-over-year (“yoy”). Of the total, 401MW were shipped to the Company’s own utility-scale solar power projects.

Net revenues in the fourth quarter of 2024 increased 1% qoq and decreased 11% yoy to $1.5 billion. The sequential increase primarily reflects higher third party battery energy storage solutions sales and higher project sales, partially offset by a decline in solar module average selling price (“ASP”) and shipment volume.

The yoy decrease primarily reflects a decline in solar module ASPs, partially offset by higher battery energy storage solutions sales and higher project sales.

Gross profit in the fourth quarter of 2024 was $217 million, down 12% qoq and up 2% yoy. Gross margin in the fourth quarter of 2024 was 14.3%, compared to 16.4% in the third quarter of 2024 and 12.5% in the fourth quarter of 2023. The gross margin sequential decrease was primarily caused by lower module ASPs. The gross margin yoy increases were primarily driven by higher margin contribution from third party battery energy storage solutions sales and project sales.

Total operating expenses in the fourth quarter of 2024 were $344 million, compared to $247 million in the third quarter of 2024 and $213 million in the fourth quarter of 2023. The sequential increase was primarily caused by impairment charges related to certain manufacturing and solar assets. The yoy increase was primarily due to the impairment charges and higher shipping and handling expenses.

Depreciation and amortization charges in the fourth quarter of 2024 were $135 million, compared to $134 million in the third quarter of 2024 and $89 million in the fourth quarter of 2023. The sequential and yoy increases were primarily driven by the payment of vertical integration investments made by the Company over the past two years and incremental capacity in key strategic markets.

Net interest expense in the fourth quarter of 2024 was $9 million, compared to $20 million in the third quarter of 2024 and $18 million in the fourth quarter of 2023. The sequential and yoy decrease were mainly due to higher interest income.

Derivative loss from hedging, net of foreign exchange gains, in the fourth quarter of 2024 was $10 million, compared to a net loss of $4 million in the third quarter of 2024 and a net gain of less than $1 million in the fourth quarter of 2023.

Net income attributable to Canadian Solar in accordance with generally accepted accounting principles in the United States of America (“GAAP”) in the fourth quarter of 2024 was $34 million, or $0.48 per diluted share, compared to a net loss of $14 million, or $0.31 per diluted share, in the third quarter of 2024, and net loss of $1 million, or $0.02 per diluted share, in the fourth quarter of 2023.

Adjusted net loss attributable to Canadian Solar Inc. (non-GAAP) was $99 million and adjusted loss per share - diluted was $1.47 a share in the fourth quarter of 2024, compared to $14 million or $0.31 per share in the third quarter of 2024, and $1 million or $0.02 per share in the fourth quarter of 2023. Adjusted net loss attributable to Canadian Solar Inc. and adjusted loss per share - diluted in the fourth quarter of 2024 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 Segment - HLBV for definition and About Non-GAAP Financial Measures for reconciliation to nearest GAAP measures.

Net cash flow provided by operating activities in the fourth quarter of 2024 was $66 million, compared to net cash flow used in operating activities of $231 million in the third quarter of 2024 and net cash flow provided by operating activities of $190 million in the fourth quarter of 2023.

Total debt was $5.2 billion as of December 31, 2024, including $2.4 billion, $2.6 billion, and $0.2 billion related to CSI Solar, Recurrent Energy, and convertible notes, respectively. Total debt decreased as compared to $5.4 billion as of September 30, 2024, mainly due to fluctuation in foreign exchanges on foreign currency denominated debt.

Business Segments

The Company has two business segments: Recurrent Energy and CSI Solar. The two businesses operate as follows:

Recurrent Energy Segment

As of December 31, 2024, the Company held a leading position with a total global solar development pipeline of 25 GWp and a battery energy storage development pipeline of 75 GWh.

The business model consists of three key drivers:

In October 2024, the Company announced it had achieved the final closing of a $500 million investment in Recurrent Energy by BlackRock through a fund management by BlackRock’s Climate Infrastructure business. As agreed between the parties, BlackRock's total investment represents 20% of the outstanding fully diluted shares of Recurrent Energy on an as-converted basis, as determined immediately upon closing. Canadian Solar will continue to own the remaining majority shares of Recurrent Energy.

This milestone enables Recurrent Energy to advance investment in its high value project development portfolio, supporting its strategic transition from a pure developer to a developer plus long-term owner and operator in select markets including the U.S. and Europe. This transition will allow Recurrent Energy to generate more stable long-term revenue in low-risk currencies and capture greater value from its diversified global project development pipeline.

Project Development Pipeline – Solar

As of December 31, 2024, Recurrent Energy’s total solar project development pipeline was 24.9 GWp, including 1.9 GWp under construction, 4.2 GWp of backlog, and 18.8 GWp of projects in advanced and early-stage pipelines, defined as follows:

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 partnership with tax equity investors in U.S. solar power and battery energy storage projects. This method allocates income or loss based on changes in each investor’s claim on the net assets of the projects.

The following table presents Recurrent Energy’s total solar project development pipeline.

*All numbers are gross MWp.

Business Outlook

The Company’s business outlook is based on management’s current views and estimates given factors such as existing market conditions, order book, production capacity, input material prices, foreign exchange fluctuations, the anticipated timing of project sales, and the global economic environment. This outlook is subject to uncertainty with respect to, among other things, customer demand, project construction and sale schedules, product sales prices and costs, supply chain constraints, and geopolitical conflicts. Management’s views and estimates are subject to change without notice.

For the first quarter of 2025, the Company expects total revenue to be in the range of $1.0 billion to $1.2 billion. Gross margin is expected to be between 9% and 11%. Total module shipments recognized as revenues by CSI Solar are expected to be in the range of 6.4 GW to 6.7 GW, including approximately 400 MW to the Company’s own projects. Total battery energy storage shipments by CSI Solar in the first quarter of 2025 are expected to be around 800 MWh, including about 150 MWh to the Company’s own projects.

For the full year of 2025, the Company reiterates its prior outlook for CSI Solar's total module shipments to be in the range of 30 GW to 35 GW, including approximately 1 GW to the Company’s projects. The Company also reiterates its prior outlook for CSI Solar's total battery energy storage shipments, projected to be in the range of 11 GWh to 13 GWh, including approximately 1 GWh to the Company's own projects. The Company's total revenue is expected to be in the range of $7.3 billion to $8.3 billion.

Dr. Shawn Qu, Chairman and CEO, commented, “First quarter margins will be impacted by lower contribution from our storage business due to seasonally smaller shipment volumes, trade-related duties and tariffs. Additionally, softer margins from Recurrent project asset sales will weigh on segment performance. Amid ongoing consolidation in the solar market, we remain committed to prioritizing profitability over volume. Looking ahead, we are confident that margin contributions from storage shipments will help improve group-level margins, as contracted volumes provide visibility into higher shipment levels by CSI Solar throughout the year.”
