Entry into A Material Definitive Agreement; Formation of Joint Venture

As previously disclosed in the Report on Form 6-K furnished by Mint Incorporation Limited, a company incorporated in the British Virgin Islands (the “Company”) on February 9, 2026, the Company’s wholly-owned subsidiary, Aspiration X Limited, a company incorporated in the British Virgin Islands (“Aspiration X”) has signed a non-binding Memorandum of Understanding (“MOU”) with a renowned delivery robotics company, Rice Robotics Holdings Limited (“Rice Robotics”), relating to the proposed formation of a joint venture company (the “Joint Venture”).

On May 22, 2026, Aspiration X and Rice Robotics entered into a joint venture agreement (the “JV Agreement”), pursuant to which the parties agreed to form and operate the Joint Venture through a private limited company incorporated under the laws of the British Virgin Islands to be named “Rice Robotics AGI Holding Limited”. Upon formation, the Joint Venture will be owned as to 87.5% by Aspiration X and/or its nominee(s) and 12.5% by Rice Robotics. The board of directors of the Joint Venture will consist of four members, of whom two will be nominated by Aspiration X and two will be nominated by Rice Robotics.

The Joint Venture will focus on the development and sales of the next generation of AI companion robots, or as may be expanded or changed by the Joint Venture from time to time in accordance with the JV Agreement.

Pursuant to the JV Agreement, Aspiration X and/or its nominee(s) will contribute HK$15,000,000 in funding, as well as provide human resources and research and development support to the Joint Venture. On the other hand, Rice Robotics has agreed to transfer or otherwise procure the transfer of three companies, namely RICE ROBOTICS (HONG KONG) LIMITED, a company incorporated in Hong Kong with limited liability, RICE AI HOLDING LIMITED, a company incorporated under the laws of the British Virgin Islands, and RICE ROBOTICS KK, a joint stock corporation (Kabushiki kaisha) organized under the laws of Japan, to the Joint Venture. Rice Robotics will also provide the Joint Venture with its existing technology, intellectual property, clients, know-how and marketing and sales support. The JV Agreement also contains customary provisions relating to governance of the Joint Venture, including shareholder consent rights for certain significant matters, transfer restrictions, and pre-emptive rights in connection with future issuances of shares of the Joint Venture.

On May 28, 2026, the Company issued a press release entitled “Mint and Rice Robotics Launch Joint Venture to Expand AI Companion Robot Business with HK$15M in funding”. A copy of this press release is furnished herewith as Exhibit 99.1.

On the same day, the Company issued another press release entitled “Mint’s New JV Rice Robotics AGI Integrates Fan-Favorite B.Duck IP for Companion Robot Debut at Licensing Expo Las Vegas”. A copy of this press release is furnished herewith as Exhibit 99.2.

This report, including Exhibits 99.1 and 99.2 hereto, is incorporated by reference into the Company’s registration statement on Form F-3, as amended, filed with the Securities and Exchange Commission on May 19, 2026 (File No. 333-296027) and shall be deemed to be a part thereof from the date on which this report is furnished, to the extent not superseded by documents or reports subsequently filed or furnished.
