(hereinafter referred to as "Tianshan Aluminum," "the Company," or "this Company") has provided maximum amount guarantee security for the following: 300 million RMB in principal creditor's rights held by Ping An Bank Co., Ltd.

(hereinafter "Tianlv Limited"); 1.1 billion RMB in principal creditor's rights held by Shanghai Pudong Development Bank Co., Ltd.

LTD. (hereinafter "Singapore Titan"), under a joint and several liability guarantee.

(II) Guarantee Deliberation

The company held the 19th meeting of the 6th Board of Directors and the 2025 3rd Extraordinary General Meeting on December 2, 2025, and December 18, 2025, respectively, to deliberate and approve the "Proposal on the Estimated Annual Guarantee Quota for 2026." According to the resolution, for the 2026 fiscal year, the company and its wholly-owned subsidiaries and second-tier subsidiaries may provide guarantees for financing and daily operations within the scope of the consolidated financial statements, with a total new guarantee quota not exceeding 23 billion RMB. The company may reallocate guarantee quotas among eligible guarantee objects based on actual conditions, provided that quotas cannot be reallocated between companies with asset-liability ratios exceeding 70% and those not exceeding 70%.

II. Usage of Guarantee Quota

Prior to this guarantee, the available quota for Singapore Titan was 500 million RMB, which was insufficient for the 1.7 billion RMB joint and several liability guarantee provided by the company to Singapore Titan via Oversea-Chinese Banking Corporation Limited. To facilitate business operations, the company has reallocated unused quotas from Shihezi Xinren Battery Aluminum Foil Technology Co., Ltd. (300 million RMB), Shanghai Xinran Industrial Co., Ltd. (600 million RMB), Jiangyin Xinren Aluminum Foil Technology Co., Ltd. (200 million RMB), and MIGHTY SKY INTERNATIONAL PTE. LTD. (500 million RMB) to Singapore Titan.
