Jinyu Group: Jinyu Hangjia supplies aerated products for the BEST project in Hefei, Anhui, achieving a small proportion of business income in the company's revenue scale.

Jinyu Group issued a abnormal announcement. The closing price of the company's A-shares on January 12th and January 13th, 2026, increased by a cumulative deviation value exceeding 20% for two consecutive trading days. According to the relevant provisions of the "Shanghai Stock Exchange Trading Rules", this constitutes abnormal trading volatility of the stock. The company is aware of market rumors. From January to September 2025, the company's holding subsidiary Jinyu Hangjia supplied aerated products for the BEST project in Hefei, Anhui, generating revenue of 587,000 yuan; its wholly-owned subsidiary Tongda Refractory supplied refractory materials for the four major launch sites, generating business revenue of 44.73 million yuan. Compared to the company's revenue of 69.489 billion yuan in the first three quarters of 2025, this accounts for a very small proportion.
