Management explicitly flagged several structural headwinds and execution risks. These include the potential for volatility in the solar power and battery energy storage market and industry conditions, including oversupply of polysilicon, solar wafers, cells, and modules, which may cause downward pressure on prices ⁶⁰. Governments may revise, reduce, or eliminate incentives and policy support schemes for solar power and battery energy storage, including those contained in the IRA and OBBBA ⁶¹. Global economic conditions, including inflationary pressures and higher interest rates, may adversely impact business prospects, results of operations, and cash flows ⁶². Project construction activities may not complete on time, and development and construction costs could increase, leading to lower returns on investment ⁶³. The company also faces risks related to offtake contracts, including failure or delay in entering into contracts, defaults by counterparties, and contingent contractual terms ⁶⁴. International business operations are subject to complex and evolving laws, regulations, policies, trade restrictions, and geopolitical risks, which could increase compliance costs, disrupt operations, and delay project execution ⁶⁵. Antidumping and countervailing duty determinations in the U.S., as well as other trade measures like Section 232 and Section 301 tariffs, could adversely affect the company ⁶⁶.

The company faces material risks from global economic conditions, including inflationary pressures and higher interest rates, which could increase supplier costs, wages, operating costs, and financing costs, potentially reducing profitability and cash flows if not passed on to customers ⁶⁷. Geopolitical tensions and conflicts, such as the Russia-Ukraine conflict and the Israel-Gaza conflict, create global security concerns and impact international business ⁶⁸. Regulatory risks include the potential for governments to revise, reduce, or eliminate incentives and policy support schemes for solar power and battery energy storage, such as those under the IRA and OBBBA, which could adversely affect profitability and project economics ⁶⁹. Trade barriers, including antidumping and countervailing duties, Section 232 and Section 301 tariffs, and reciprocal tariffs under the IEEPA, could increase product costs, impact competitiveness, and lead to supply chain disruptions or unanticipated liabilities ⁷⁰. For example, the USDOC's final countervailing duty rate (all others) applicable to Canadian Solar in the Solar 3 Thailand investigations is 255.39%, and the final antidumping duty rate (all others) is 111.45% ⁷¹. Operational risks include oversupply of polysilicon, solar wafers, cells, and modules, causing downward pressure on prices, and potential issues with manufacturing capacity expansion and operational initiatives ⁷². The company is also exposed to defects or performance issues in products, which could result in significant warranty claims, with accrued warranty liability of $138.4 million as of December 31, 2025 ⁷³. Cybersecurity incidents, including power outages, system failures, unauthorized access, malware, ransomware, and data breaches, could disrupt business and expose the company to legal claims, regulatory penalties, and financial damage ⁷⁴.

Management's overall tone emphasizes strategic adaptation to market dynamics and a commitment to long-term sustainability and innovation. They highlight the importance of balancing long-term asset ownership with selective project sales to generate operating cash flows and manage capital requirements ⁷⁵. A key strategic priority is the expansion of U.S. manufacturing capabilities and domestic production, as evidenced by significant investments in new facilities in Mesquite, Texas, and Jeffersonville, Indiana, and a planned R&D hub in Shelbyville, Kentucky ⁷⁶. Another priority is the growth and innovation in the battery energy storage business, with a focus on proprietary products like SolBank and FlexBank, and expanding the contracted backlog ⁷⁷. Management also stresses continuous cost reduction through improvements in solar cell conversion technology, manufacturing yields, and material sourcing to mitigate pressure from declining solar module average selling prices ⁷⁸. They are closely monitoring macroeconomic developments, including inflation, interest rates, monetary policy changes, and foreign currency fluctuations, as well as elevated geopolitical tensions, acknowledging their potential adverse impact on business ⁷⁹. The company is committed to ESG principles, including reducing GHG emissions, energy, water, and waste intensities, and has set science-based near-term and net-zero targets validated by SBTi in December 2025 ⁸⁰.
