Announcement on the estimated amount of external guarantees

The company and all members of the board of directors guarantee that the information disclosed is true, accurate and complete, and contains no false records, misleading statements or major omissions.

Guoke Hengtai (Beijing) Medical Technology Co., Ltd. (hereinafter referred to as the "Company") held the 50th meeting of the third board of directors on June 25, 2026, and reviewed and approved the "Proposal on the Estimation of the Amount of External Guarantees". This matter still needs to be submitted to the company's shareholders' meeting for review. The specific contents are hereby announced as follows:

1. Overview of external guarantees

According to the company's business development needs, in the next twelve months, the company plans to provide a total guarantee line of 1.489 billion yuan to subsidiaries within the scope of consolidated statements. Among them, the amount of guarantees provided for subsidiaries within the scope of consolidated statements with an asset-liability ratio of more than 70% is 1.220 billion yuan; the amount of guarantees provided for subsidiaries within the scope of consolidated statements with an asset-liability ratio of less than 70% is 269 million yuan.

The above-mentioned limit is controlled based on the actual effective amount (the guarantee that continues during the period when the guarantee contract is signed and the limit is valid). Within the scope of the total guarantee limit, the guarantee limit can be adjusted among the company's subsidiaries, but a subsidiary with an asset-liability ratio of more than 70% when the adjustment occurs can only obtain a guarantee limit from a subsidiary with an asset-liability ratio of more than 70% at the time of review by the shareholders' meeting.

External guarantee matters within the total guarantee limit are authorized hierarchically according to the guarantee balance. For external guarantees with a guarantee balance of no more than 1.253 billion yuan (no more than 50% of the net assets attributable to the parent company in the latest audited consolidated accounting statement), the general manager's office is authorized to review a single guarantee matter without submitting it to the board of directors or shareholders' meeting for review. For external guarantees with a guarantee balance exceeding 1.253 billion yuan, the board of directors is authorized to review a single guarantee matter without submitting it to the shareholders' meeting for review. The aforementioned authorization is valid until the next shareholders' meeting to review and approve the new total guarantee amount.

For guarantees that exceed the company's shareholding ratio, other shareholders of the guaranteed subsidiary should provide sufficient counter-guarantee with realizable value for the portion of the guarantee that exceeds the company's shareholding ratio. The value of the counter-guaranteed assets shall not be less than 1.3 times the amount of the guarantee exceeding the company's shareholding ratio. If it is indeed impossible to provide effective counter-guarantee due to objective circumstances, on the premise that the guarantee risk is controllable, the company will collect corresponding guarantee fees from the guaranteed subsidiary to prevent compensation risks.

Guarantee fees are collected in the following ways: (1) For credit policy guarantee matters, within 30 days from the date of signing the guarantee agreement, a one-time full payment will be collected in advance from the guaranteed subsidiary based on the amount of the guarantee agreement and the guarantee period. (2) For bank credit guarantee matters, within one month after the effective date of the guarantee contract and the actual occurrence of the guarantee matter (actual occurrence of the debt to be paid off), the actual guarantee amount will be collected in advance from the guaranteed subsidiary in full in one go; for the guarantee part corresponding to the company's shareholding ratio, the guarantee rate is in principle not less than 1.00%/year; for the guarantee part corresponding to the non-company's shareholding ratio, the guarantee rate is in principle not less than 2.50%/year.

4. Main contents of the guarantee agreement

Guarantee method: joint liability guarantee guarantee
Guarantee period: The authorization is valid until the next shareholder meeting approves the new total guarantee amount.
Guarantee amount: The company plans to provide a guarantee amount of 1.489 billion yuan to subsidiaries within the scope of consolidated statements.
Guarantee, counter-guarantee and guarantee costs: For guarantees that exceed the company's shareholding ratio, other shareholders of the guaranteed subsidiary should provide sufficient counter-guarantee with realizable value for the guarantee that exceeds the company's shareholding ratio. The value of the counter-guaranteed assets shall not be less than 1.3 times the amount guaranteed in excess of the company's shareholding ratio. If it is indeed impossible to provide effective counter-guarantee due to objective circumstances, on the premise that the guarantee risk is controllable, the company will collect corresponding guarantee fees from the guaranteed subsidiary to prevent compensation risks.

The foregoing content is the basic content of the guarantee agreement. The actual guarantee situation shall be subject to the officially signed guarantee document. The company's board of directors proposed to the second extraordinary shareholders' meeting in 2026 to authorize relevant persons to handle specific guarantee matters within the above-mentioned validity period and authorization limit, and to perform internal control and approval procedures in accordance with the relevant provisions of the "Articles of Association" and the internal control system. When guarantee matters actually occur, the company will disclose it in a timely manner, and the guarantee balance at any point in time will not exceed the guarantee limit approved by the shareholders' meeting. If there are major changes in the above guarantee matters, the company will also perform its information disclosure obligations in a timely manner in accordance with legal and regulatory requirements.

5. Opinions of the Board of Directors

The board of directors believes that the estimated amount of the company's external guarantee this time is in line with the company's business development and working capital needs. The guaranteed objects are all subsidiaries within the scope of the company's consolidated statements. The reputation and operating status of the subsidiaries are good, and the financial risks are controllable. The estimated amount of guarantee will not harm the interests of the company and all shareholders. The company's board of directors agreed on the estimated guarantee amount and agreed to submit the proposal to the company's shareholders' meeting for review.
