In accordance with the "Several Opinions of the State Council on Further Promoting the Healthy Development of the Capital Market" (Guo Fa [2014] No. 17), 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), and the "Guiding Opinions on Matters Related to the Dilution of Immediate Returns from Initial Public Offerings, Refinancing, and Major Asset Restructuring" (CSRC Announcement [2015] No. 31), in order to protect the interests of small and medium investors, Yunnan Wason Bio-technology Co., Ltd. (hereinafter referred to as the "Company") has conducted a thorough analysis of the impact of the dilution of immediate returns from the issuance of A shares to specific objects (hereinafter referred to as the "Issuance" or "Issuance of Shares to Specific Objects") in 2026 and has proposed specific measures to fill in the returns. Relevant parties have made commitments to ensure the effective implementation of the Company's measures to fill in the returns. The specific content is as follows:

I. Analysis of the Impact of the Issuance of Shares on the Dilution of the Company's Immediate Returns

The number of shares to be issued by the Company shall be determined by dividing the total amount of raised funds by the issue price (if the calculation result is less than 1 share, the remainder shall be rounded down, and the consideration for the fractional share shall be gifted to the issuer), not exceeding 207,983,751 shares, which does not exceed 30% of the total share capital before the issuance. The Company has conducted relevant calculations on the impact of this issuance on the Company's main financial indicators in the year of issuance. The specific calculation process is as follows:

(I) Assumptions for Calculation

1. It is assumed that the issuance will be completed by the end of December 2026. This completion time is only an estimate, and the final completion time will be subject to the actual completion of the issuance.

2. It is assumed that the number of shares to be issued is 207,983,751 shares. This assumption is only for calculating the impact of this issuance on the Company's earnings per share, and does not represent the Company's judgment on the actual completion time and number of shares issued. The final determination shall be subject to the actual completion time and number of shares issued after registration with the China Securities Regulatory Commission.

3. It is assumed that the macroeconomic environment, the securities industry, and the Company's operating environment will not undergo any major adverse changes.

5. The impact of factors other than the number of shares issued on the share capital is not considered.

It is assumed that in 2026, the net profit attributable to the parent company's shareholders and the net profit after deducting non-recurring gains and losses attributable to the parent company's shareholders will fall into the following three scenarios:

(1) In 2026, the net profit attributable to the parent company's shareholders and the net profit after deducting non-recurring gains and losses attributable to the parent company's shareholders will decrease by 10% compared to 2025.

(2) In 2026, the net profit attributable to the parent company's shareholders and the net profit after deducting non-recurring gains and losses attributable to the parent company's shareholders will remain the same as in 2025.
