On July 14, 2025, the Company entered into an equity transfer agreement to sell approximately 20.3% of outstanding equity interest in the JV Company for an aggregate cash consideration of $150 million. On August 29, 2025, the amended shareholders’ agreement for the JV Company was signed, which reduced the Company’s equity interest in the JV Company by 20.3% to an ownership percentage of 18.9%.

In addition, the Company recorded a receivable of $56.4 million for the remaining installments, which is included in the receivable from sale of equity interest in the JV Company line on the Condensed Consolidated Balance Sheets. The remaining installments will be received subject to satisfaction of certain conditions, which require the Company's continuing involvement, including voting in shareholder meetings to complete the transaction in accordance with the equity transfer agreement, plus other administrative actions. As a result of the sales transaction, the Company evaluated the factors that indicate the ability to exercise its significant influence to the JV Company, including but not limited to representation on the board, material intra-entity transactions, and participation in policy making process.
