One of five board members is designated by CSI Solar. These investments are accounted for under the equity method due to CSI Solar’s significant influence over the investees. In 2022, the majority interests in Marangatu Holding S.A. (“Marangatu”) and Panati Holding S.A. (“Panati”) were sold to unrelated third parties. Following these sales, the Company retained a 30% interest in each investee, recognized revenue of $12,007 and $2,259, respectively, for the year ended December 31, 2022, and derecognized net assets of $6,267 and $2,262, respectively.

Given CSIF’s board structure and voting requirements, the Company is considered to have significant influence over the investee and applies the equity method. Equity in earnings of affiliates were $15,440 and $14,610 for the years ended December 31, 2022 and 2023, respectively, and equity in losses of affiliates was $12,136 for the year ended December 31, 2024.
