Note: The Company's vendor arrangements have undergone modifications compared to the disclosure in the prospectus dated September 30, 2025. Notably, the prospectus provides for such flexibility, as it states that "The company have not entered into any definitive agreements with any of these vendors and there can be no assurance that the same vendor would be engaged to eventually supply the equipment at the same cost". As a result, the modification of vendor arrangements is consistent with the disclosure outlined in the prospectus.
