On August 25, 2025, the Company, together with the Company’s Chairman and Chief Executive Officer, Mr. Ling Ngai Lok, and the Company’s director, Mr. Haokang Zhu, formed a new subsidiary, AX Coin Limited under the laws of the Cayman Islands, in which the Company holds 32,000 shares out of 50,000 outstanding shares, accounting for 64% of the entity. On October 23, 2025, the Company transferred AX Coin HK Limited to AX Coin Limited, and as a result, AX Coin HK Limited became a wholly-owned subsidiary of AX Coin Limited. To apply for a license for the issuance of regulated stablecoins in Bahrain, on November 18, 2025, the Company formed a new wholly-owned subsidiary AXG International Management W.L.L. under AX Coin HK Limited, and on February 8, 2026, AX Coin HK Limited together with Firewood Group Limited, further set up AX Coin Bahrain B.S.C Closed, in which AX Coin HK and Firewood hold 95% and 5% of the entity, respectively. AX Coin’s principal business is the issuance of enterprise-grade stablecoins and the operation of a B2B infrastructure platform for payments, treasury management and tokenized asset settlement, marketed under the AXCOIN brand. As of the date of this report, AX Coin focuses on obtaining licenses and establishing networks across the globe for its stablecoin business.

AX Coin’s core model centers on the issuance and management of enterprise-grade stablecoins, with revenue streams aligned with stablecoin operations and related services.

Additionally, AX Coin earns service fees from stablecoin issuance and management, including fees for stablecoin minting and redemption, as well as platform fees from its B2B infrastructure services.
