According to the standard unqualified opinion audit report issued by Lixin Certified Public Accountants (Special General Partnership), the net profit attributable to the parent company in 2025 was RMB 13,934,956.29. After deducting RMB 1,404,732.94 for the statutory surplus reserve (10% of the parent company's net profit) and adding the undistributed profit at the beginning of the year of RMB 332,443,979.27, and deducting the cash dividends paid to shareholders in 2024 of RMB 18,345,600.00, the undistributed profit in the consolidated financial statements at the end of the period was RMB 326,628,602.62, and the undistributed profit of the parent company was RMB 328,296,741.05. According to the principle of taking the lower of the undistributed profits in the consolidated financial statements and the parent company's financial statements, the profit available for distribution to shareholders is RMB 326,628,602.62. Considering the company's continuous return to investors and long-term development, the company proposes a profit distribution plan for 2025: based on the company's total share capital of 294,131,282 shares, a cash dividend of RMB 0.10 per 10 shares (tax inclusive) will be distributed to shareholders eligible for distribution. The total cash dividend is RMB 2,941,312.82 (tax inclusive). No bonus shares will be issued, and no capital reserve will be used to increase share capital. The remaining undistributed profit after this dividend distribution will be carried forward to subsequent periods. If the company's share capital changes due to convertible bond conversion, share buybacks, exercise of equity incentives, or issuance of new shares in refinancing before the profit distribution plan is implemented, the distribution will be implemented based on the adjusted share capital, and the above distribution ratio will remain unchanged. This proposal has been reviewed and approved by the Company's Board of Directors' Audit Committee and the Board of Directors' Independent Directors' Special Committee. This proposal needs to be submitted to the 2025 Shareholders' Meeting for review. VI.
