Separately, AMEC’s major shareholder, Sunton (Shanghai) Investment Co., Ltd., announced a plan to reduce its stake. Sunton, which holds 80,996,822 shares (12.94% of the total share capital), intends to sell up to 2% of the company's total share capital through block trades between September 17, 2025, and December 16, 2025. This reduction is driven by its own operational and management needs.

The latest reduction plan follows a previous sale by Sunton between May 11, 2023, and November 10, 2023, where it sold 12,522,906 shares. All shares involved in these transactions were acquired prior to AMEC’s initial public offering.
