1. Overview of Guarantee Situation

(1) Basic Guarantee Information

To meet the funding needs of its subsidiaries’ business development, the wholly-owned subsidiary Jinjian Electric Technology (Heze) Co., Ltd. (hereinafter referred to as “Jinjian Heze”) plans to apply for a financing lease loan of no more than RMB 30 million from Haier Financial Leasing Co., Ltd. The company will provide joint liability guarantee for this loan, with specific terms subject to the contract signed at that time.

(2) Internal Decision-Making Procedures

On January 7, 2026, the Company held the third meeting of the fourth Board of Directors, which reviewed and approved the “Proposal on the Estimated External Guarantee Limit for 2026.” It agreed that the Company could provide a new guarantee limit of no more than RMB 500 million for its wholly-owned subsidiaries in 2026. The Board authorized the Chairman to handle all specific matters related to the guarantee within the estimated limit. According to the Company’s Articles of Association, this proposal does not need to be submitted to the shareholders’ meeting for approval. For details, see the Company’s announcement on January 8, 2026, on the Shanghai Stock Exchange website (www.sse.com.cn): “Announcement of the Resolution of the Third Meeting of the Fourth Board of Directors of Jinjian Electric Technology Co., Ltd.” (Announcement No.: 2026-001), and “Announcement on the Estimated External Guarantee Limit for 2026” (Announcement No.: 2026-002).

Jinjian Heze is not a dishonest person subject to enforcement.

3. Main Contents of the Guarantee Agreement

The company and Jinjian Heze have not yet signed a financing lease loan contract or guarantee contract. The proposed loan amount and guarantee limit are only the amounts Jinjian Heze intends to apply for and the company intends to provide as guarantees. The actual loan amount and guarantee amount are subject to approval by Haier Financial Leasing Co., Ltd. and the contracts signed.

4. Necessity and Rationality of the Guarantee

This guarantee is to meet the daily operational needs of the wholly-owned subsidiary. Obtaining the loan will help Jinjian Heze expand its business operations. Providing a guarantee for the loan aligns with the overall interests of the company’s shareholders. The company has 100% control over Jinjian Heze, and the guarantee risk is manageable, which will not adversely affect the interests of the company or all shareholders.

5. Board of Directors’ Opinion

The Board believes that the guarantee for the wholly-owned subsidiary is to meet the company’s daily operational funding needs, which is beneficial for the development of the company’s main business. The guarantor is mainly a wholly-owned subsidiary within the company’s consolidated financial statements. After thorough evaluation, the Board considers that the proposed external guarantee limit for 2026 is in line with the company’s overall interests and development strategy, and does not harm the interests of the company or its shareholders.

6. Total External Guarantees and Overdue Guarantees

As of the date of this announcement, the total guarantee amount provided by the company to its wholly-owned subsidiaries is RMB 171,197,465.00 (the total guarantee amount refers to the actual outstanding principal balance of guarantees, excluding the newly proposed guarantee amount), representing 29.53% of the company’s most recent audited net assets and 6.67% of total assets.

As of the date of this announcement, the company has no overdue guarantees and no guarantees involved in litigation.

This announcement is hereby made.
