China Hongqiao issued an announcement stating that Hongchuang Holdings plans to issue new shares to the existing shareholders of Hongtuo Industrial (including Weiqiao Aluminum & Electricity) to purchase the target shares held by them and related transaction documents. On December 31, 2025, Hongchuang Holdings received the "Approval of the Registration of Shandong Hongchuang Aluminum Holding Co., Ltd.'s Issuance of Shares to Purchase Assets" (CSRC Approval No. [2025] 2970) issued by the China Securities Regulatory Commission. The main content of the approval document is to approve Hongchuang Holdings' registration application for issuing shares to nine counterparties, including Weiqiao Aluminum & Electricity, to purchase related assets. Upon receiving the aforementioned approval, on the same day, 100% of the equity of Hongtuo Industrial was transferred and registered under the name of Hongchuang Holdings, and the transfer of the target assets of this transaction has been completed, making Hongtuo Industrial a wholly-owned subsidiary of Hongchuang Holdings. Hongchuang Holdings will, in accordance with the requirements of the aforementioned approval documents and relevant laws and regulations, and the authorization of the Hongchuang Holdings shareholders' meeting, handle other matters related to this transaction within the prescribed period, including but not limited to the registration and listing procedures related to the newly issued shares of Hongchuang Holdings.

In December 2025, Hongchuang Holdings announced that its major restructuring plan to acquire 100% equity of Hongtuo Industrial for RMB 63.518 billion had been approved by the China Securities Regulatory Commission (CSRC) on December 31, 2025, and the transfer of the target assets was completed on January 5, 2026. Following this acquisition, Hongtuo Industrial will become a wholly-owned subsidiary of Hongchuang Holdings and be included in its consolidated financial statements, effectively reducing the proportion of related-party transactions for the listed company. The issue of competition within the same industry will also be resolved. Furthermore, profitability and asset size will be significantly improved. Both parties in this transaction belong to Weiqiao Group. Hongchuang Holdings has an annual production capacity of 200,000 tons of cast-rolled steel sheets, 200,000 tons of cold-rolled steel sheets, and 120,000 tons of aluminum foil. Hongtuo Industrial has an annual electrolytic aluminum production capacity of 6.459 million tons and an annual alumina production capacity of 19 million tons, accounting for 14.5% and 18.2% of the national total capacity, respectively. Its main business is the production and sales of electrolytic aluminum, alumina, and deep-processed aluminum products.

On December 17th, the 2025 (22nd) World's 500 Most Valuable Brands ranking, exclusively compiled by the World Brand Lab, was unveiled in New York, USA, with a press conference held in Hong Kong. The Weiqiao brand jumped to 387th place, an improvement of 15 places from last year, demonstrating its continued rise in brand value and global influence. This marks the seventh consecutive year that the Weiqiao brand has been among the world's 500 most valuable brands.

On June 6, 2025, Allison Ju, Senior Manager of SMM's Aluminum Overseas Sales Team, and Cathy Liu, SMM's Aluminum Analyst, led a delegation to PT Well Harvest Winning Alumina Refinery (hereinafter referred to as "WHW"), where they held in-depth discussions with WHW's management at its Jakarta office.
