Announcement on Diluted Immediate Returns, Measures to Compensate, and Commitments of Relevant Parties Regarding the Private Placement of A-Share Stocks in 2026

The Company and all members of the Board of Directors guarantee that the information disclosed is true, accurate, and complete, and that there are no false records, misleading statements, or material omissions.

In accordance with the "Opinions of the General Office of the State Council on Further Strengthening the Protection of the Legal Rights and Interests of Small and Medium Investors in the Capital Market" (Guo Ban Fa [2013] No. 110), the "Several Opinions of the State Council on Further Promoting the Healthy Development of the Capital Market" (Guo Ban Fa [2014] No. 17), and the "Guiding Opinions on Matters Concerning the Dilution of Immediate Returns from Issuance and Refinancing and Major Asset Restructuring" (CSRC Announcement [2015] No. 31), the Company has analyzed the potential impact of this private placement of shares (hereinafter referred to as the "Offering") on immediate returns. Based on the actual situation, measures to compensate for the dilution of returns have been proposed, and relevant parties have made commitments to ensure the effective implementation of these measures. The specific details are as follows:

I. Impact of the Offering on the Company's Main Financial Indicators

(I) Main Assumptions

1. It is assumed that the macroeconomic environment, industrial policies, industry development trends, product market conditions, and the Company's operating environment will not undergo significant adverse changes.

2. It is assumed that the Offering will be completed by the end of November 2026. This completion time is for the purpose of calculating the impact of the Offering on immediate returns and main financial indicators and does not constitute a commitment to the actual completion date. The final completion date will be subject to the actual completion of the issuance after registration is approved by the China Securities Regulatory Commission (CSRC).

3. It is assumed that the number of shares issued will be the upper limit for this private placement of shares, which is 30,000,000 shares (inclusive of the principal amount). The aforementioned number of shares for the private placement is a hypothetical assumption for calculation purposes. The final number of shares issued will be determined by the Company's Board of Directors, based on the authorization of the shareholders' meeting, relevant regulations of the CSRC, and the actual situation at the time of issuance, in consultation with the sponsor (lead underwriter) of the Offering, after review by the Shenzhen Stock Exchange and approval for registration by the CSRC.

4. When forecasting the Company's total share capital, it is based on the Company's total share capital of 100,000,000 shares as of the announcement date of this plan. Only the impact of the Offering is considered, and changes in share capital due to capital increases, repurchases, share-based payments, and other factors are not considered.

5. The impact of the raised funds on the Company's production and operation, financial status (such as financial expenses, investment income), etc., after they are in place is not considered.

6. According to the Company's disclosed 2025 annual financial report data, the net profit attributable to shareholders of the listed company in 2025 was 22.2532 million yuan, and the net profit attributable to shareholders of the listed company after deducting non-recurring gains and losses was 21.9188 million yuan. Based on this data, and in accordance with the Company's actual operating conditions and the principle of prudence, the net profit attributable to shareholders of the listed company and the net profit attributable to shareholders of the listed company after deducting non-recurring gains and losses for 2026 are assumed to be calculated under the following three scenarios: (1) a 200% increase compared to 2025; (2) a 100% increase compared to 2025; (3) remaining flat compared to 2025. This assumption is only for the purpose of calculating the impact of the Offering on immediate returns and main financial indicators and does not constitute a profit forecast or profit commitment by the Company.
