ORGANIZATION AND PRINCIPAL ACTIVITIES</b></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:18pt;margin:0pt 0pt 12pt 0pt;">Canadian Solar Inc.(“CSI”) and its subsidiaries (collectively, the “Company”) is one of the world’s largest solar technology and renewable energy companies, leading manufacturer of solar photovoltaic modules, provider of solar energy and battery energy storage solutions, and developer of utility-scale solar power and battery energy storage projects. The Company’s geographic footprint is diversified, as its sales as well as development pipeline in various stages of development are located across North America, South America, Europe, South Africa, the Middle East, Australia and Asia.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:18pt;margin:0pt 0pt 12pt 0pt;">CSI was incorporated pursuant to the laws of the Province of Ontario in October 2001, and in 2006, changed its jurisdiction by continuing under the Canadian federal corporate statute, the Canada Business Corporations Act, or CBCA. In July 2020, CSI filed articles of continuance to change its jurisdiction from the federal jurisdiction of Canada to the provincial jurisdiction of the Province of British Columbia. In July 2022, CSI completed its continuance from the corporate jurisdiction under the laws of the province of British Columbia to the corporate jurisdiction under the laws of the province of Ontario pursuant to the Business Corporations Act (Ontario), or OBCA. As a result, CSI is governed by the OBCA, and its affairs are governed by its notice of articles and the articles.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:18pt;margin:0pt 0pt 12pt 0pt;">In July 2020, the Company announced its plan to carve-out and publicly list its subsidiary, CSI Solar Co., Ltd. (“CSI Solar”) in China (the “IPO”). Refer to Note 22 for further information.To qualify CSI Solar for the planned carve-out IPO and to bring in leading institutional investors and strategic partners (“third-party investors”), the Company completed a capital raise in 2020 by transferring a portion of CSI Solar shares to third-party investors for an aggregate consideration of RMB1.50 billion (approximately $219,000 on the date of transaction), and selected employees also purchased existing CSI Solar shares from the Company for an aggregated consideration of RMB31 million (approximately $4,500 on the date of transaction), following which, the third-party investors and Canadian Solar employees, in aggregate, owned 20.4% of CSI Solar as of December 31, 2022. The Company’s wholly-owned global project development business, its Recurrent Energy segment, is not a part of the IPO transaction.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:18pt;margin:0pt 0pt 12pt 0pt;">In addition, CSI Solar approved an employee incentive plan and utilized a limited liability partnership as a vehicle to hold CSI Solar shares that were used under the employee incentive plan. Eligible CSI Solar directors, employees and board members have collectively subscribed to equity interest in the partnership for an aggregate of RMB248 million ($36,342 on the date of transaction), for which the vesting conditions include the completion of the IPO and the service period.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:18pt;margin:0pt 0pt 12pt 0pt;">On June 9 , 2023, CSI Solar completed its IPO and its shares began trading on the Science and Technology Innovation Board (the “STAR Market”) of the Shanghai Stock Exchange (the “SSE”). In the STAR IPO, CSI Solar raised proceeds of $927,897, net of transaction costs. Upon completion of the IPO and as of December 31, 2023, the Company owned 62.24% of the outstanding CSI Solar shares. The Company continues to present CSI Solar as a segment subsequent to the IPO.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:18pt;margin:0pt 0pt 12pt 0pt;">As of December 31, 2023, the Company operated two reportable segments as follows:</p><table style="border-collapse:collapse;font-family:'Times New Roman','Times','serif';font-size:12pt;margin-bottom:0pt;margin-top:0pt;table-layout:fixed;width:100%;border:0pt;"><tr><td style="width:18pt;"></td><td style="font-family:'Times New Roman','Times','serif';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:10.8pt;padding:0pt;">●</td><td style="padding:0pt;"><b style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:bold;">CSI Solar</b><span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;">, which consists of solar module and battery energy storage manufacturing, and delivery of total system solutions, including inverters, solar system kits and EPC (engineering, procurement, and construction) services.

The Company establishes an allowance for credit losses primarily based upon the age of the receivables and factors surrounding the credit risk of specific customers. With respect to advances to suppliers, such suppliers are primarily suppliers of raw materials and equipment. The Company performs ongoing credit evaluations of its suppliers’ financial conditions. The Company generally does not require collateral or security against advances to suppliers, however, it maintains a reserve for potential credit losses and such losses have historically been within management’s expectation.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:18pt;margin:0pt;">The prepayments made by the Company are unsecured and expose the Company to supplier credit risk. As of December 31, 2022 and 2023, gross prepayments made to individual suppliers in excess of 10% of total advances to suppliers are as follows:</p><p style="font-family:'Times New
