Entry into a Memorandum of Cooperation for a Proposed Joint Venture in Japan

On January 15, 2026, TryHard Holdings Limited (the “Registrant”) entered into a non-binding Memorandum of Cooperation (the “Memorandum”) with STAR PARTY HK LIMITED (“STAR PARTY HK”), setting forth the preliminary intent of the parties to explore the establishment of a joint venture company in Japan.

The proposed joint venture would serve as the core operating and investment platform for developing the “Star Party” entertainment and social space brand in the Japanese market. Pursuant to the preliminary terms outlined in the Memorandum, the joint venture company would be responsible for the localized operation and expansion of businesses under the brands “星聚会” and “STAR PARTY” (collectively, the “Star Party Brand”).

The Memorandum outlines the parties’ current intent regarding the proposed joint venture’s structure, including a tentative registered capital of 90 million Japanese Yen and a proposed equity split of 65% for STAR PARTY HK and 35% for the Registrant. The formation of the joint venture, its final capital structure, governance, and all operational terms are subject to the negotiation and execution of definitive, binding agreements.

The foregoing description of the Memorandum is a summary of the material terms of such agreement, and does not purport to be complete and is qualified in its entirety by reference to the Memorandum.

Issuance of Press Release

On January 15, 2026, the Registrant issued a press release announcing its entry into the Memorandum and describing the principal terms and conditions set forth in the Memorandum.
