Daqo New Energy’s Subsidiary Xinjiang Daqo Provides Latest Update on its Litigation Event

In April 2024, Xinjiang Daqo New Energy Co., Ltd. (“Xinjiang Daqo”), a subsidiary of Daqo New Energy (the “Company”), received a court summons relating to a contract dispute lawsuit filed against it by Xinjiang Xian’an New Materials Co., Ltd. and its affiliate, Xinjiang Dengbo New Energy Co., Ltd. The plaintiffs previously provided silicon core processing services to Xinjiang Daqo. The plaintiffs requested for termination of the business cooperation agreement with Xinjiang Daqo and for compensation from Xinjiang Daqo for their economic losses totaling RMB1,958.5 million (which was later reduced to RMB742.7 million), which consisted largely of alleged consequential damages of the plaintiffs. This litigation was previously disclosed in the Company’s annual report on Form 20-F for the year ended December 31, 2023 filed with the Securities and Exchange Commission on April 29, 2024, its press release dated July 17, 2024, its Form 6-K dated March 17, 2025, its Form 6-K dated April 22, 2025, and its press release dated September 11, 2025.

In July 2024, the Company received the first instance court’s verdict, which affirmed termination of the business cooperation agreement and ordered Xinjiang Daqo to compensate the plaintiffs for their losses and attorney fees totaling RMB3.16 million, while rejecting the plaintiffs’ claims for consequential damages. The plaintiffs appealed to the second instance court, and the second instance court vacated the decision of the first instance court and remanded the case for a retrial. In September 2025, the Company received the verdict of the first instance court’s retrial, which affirmed termination of the business cooperation agreement and ordered Xinjiang Daqo to compensate the plaintiffs for their losses and attorney fees totaling RMB3.30 million, while rejecting the plaintiffs’ claims for consequential damages.

Recently, the Company has received a court summons, in which the plaintiffs appealed to the second instance court, requesting for vacation of the first instance court’s decision and compensation from Xinjiang Daqo for their economic losses totaling RMB744.9 million, as well as costs of litigation and attorneys’ fees for the trials. The litigation’s impact on Xinjiang Daqo will be contingent upon the final verdict.
