Xining Special Steel: The proportion of rights and interests held by Qinghai Guotou and its concerted actors has increased to 21.09%.

On September 24, 2025, Xining Special Steel announced that the proportion of equity changes of Qinghai Province State-owned Assets Investment Management Co., Ltd. and its concerted action parties increased from 18.02% to 21.09%. This change was due to the Qinghai Province Third Construction Engineering Co., Ltd. and Qinghai GuoTou's equity relationship becoming a concerted action party, which did not involve the increase or decrease of each shareholder's respective shareholdings and did not trigger the obligation of mandatory takeover offer. After the change, the aforementioned concerted action parties collectively held 686,548,921 shares of the company, accounting for 21.09% of the total share capital. This change will not lead to a change in the company's controlling shareholder or ultimate controller, and will not harm the interests of the company and other shareholders. Relevant information will be disclosed on the Shanghai Stock Exchange website.
