Exchange Agreements

On May 27, 2026, GMEX Robotics Corporation, a British Virgin Islands company (the “Company”), entered into an Exchange Agreement (the “Exchange Agreement”) with an institutional investor who is the holder of its Series C Senior Secured Convertible Note issued on November 7, 2025 (the “Notes”) pursuant to a Securities Purchase Agreement, dated as of November 6, 2025, between the Company and the Holder (the “SPA”). The Exchange Agreement provides, among other things, for the Holder to exchange (the “Exchange”) the remaining balance of the Notes for a new series of senior secured convertible notes of the Company (the “Series D Notes”). The terms of the Series D Notes were substantially similar to the Series C Notes subject to certain changes in the pricing contained in the Series C Notes. As provided for in the Series D Note, the Company may from time to time voluntarily adjust the conversion price of the Series D Note to optimize cash flows and the capital structure.

The Exchange was consummated upon execution of the Exchange Agreement. The Exchange Agreement contains customary representations, warranties and agreements of the Company and the Holder. The Exchange is being conducted in reliance on the exemption from registration provided by Section 3(a)(9) of the Securities Act.

The foregoing descriptions of each of the Exchange Agreement and the Series D Notes described herein do not purport to be complete and are qualified in their entirety by reference to the complete text thereof, copies of which are filed as Exhibits to this report and are incorporated herein by reference.
