Chalco (02600) announced an adjustment to its subsidiary's capital contribution arrangement. Under the original agreement signed on December 27, 2022 among Chalco Group, Chalco, Chongqing Aluminum Development Investment, Yunnan Aluminium, and Chalco High-end Manufacturing, Yunnan Aluminium had committed to invest RMB 1.323 billion in Chalco High-end Manufacturing. This included: - RMB 90 million in cash - A 100% equity stake in Yunnan Haoxin Aluminum valued at RMB 609.4 million - Physical assets related to Yunnan Haoxin Aluminum worth RMB 623.68 million

The modification addresses unresolved property rights transfer issues concerning certain buildings earmarked for physical contribution. Yunnan Aluminium and Chalco High-end Manufacturing executed a capital replacement agreement on July 15, 2025, converting these specific building assets into equivalent cash investment. This adjustment resolves practical hurdles in implementing the original investment structure while maintaining the total committed investment value.
