UxinEnters into Joint Venture Agreement with Shijiazhuang State-Owned Enterprise

BEIJING, June 2, 2026 — Uxin Limited (“Uxin” or the “Company”) (Nasdaq: UXIN), a leading used car retailer in China, today announced a strategic partnership with Hebei Chengying Investment Promotion Operation Co., Ltd. (“Hebei Chengying”) to establish Uxin (Shijiazhuang) Automobile Maintenance Co., Ltd. (the “Joint Venture”), aiming to support the Company’s plan to establish a new used car superstore in Shijiazhuang. Pursuant to the Joint Venture Agreement, Uxin (Anhui) Industrial Investment Group Co., Ltd. (“Uxin Anhui”), a wholly-owned subsidiary of the Company, will contribute RMB30.0 million, and Hebei Chengying will contribute RMB10.0 million to the Joint Venture, respectively, representing approximately 75% and 25% of the Joint Venture’s total registered capital, respectively.

The establishment of the Joint Venture reflects an important collaboration between Uxin and state-owned enterprises in Shijiazhuang, aimed at promoting the development of the automotive aftermarket industry across North China and building a leading brand in China’s used car industry.

Mr. Wenbing Jing, President of Uxin, stated: “As the capital of Hebei Province, Shijiazhuang is a major hub in the coordinated development of the Beijing-Tianjin-Hebei region. With a population exceeding 11 million and more than 4 million registered vehicles, the city presents substantial opportunities for growth in the used car and automotive aftermarket sectors. By leveraging Uxin’s capabilities in supply chain management, digital operations, and standardized services, we plan to establish the Shijiazhuang Superstore as a regional used car circulation and service hub serving Hebei, Tianjin, and the broader Beijing-Tianjin-Hebei market. We believe this initiative will further improve the used car purchasing experience for consumers throughout North China.”
