When used in this report, the words “may”, “will”, “anticipate”, “believe”, “estimate”, “expect”, “intend”, “plan” and similar expressions, as they relate to us or our management, are intended to identify forward-looking statements. These statements reflect management’s current view of us concerning future events and are subject to certain risks, uncertainties and assumptions, including among many others: our negative operating profits may raise substantial doubt regarding our ability to continue as a going concern, our substantial customer concentration, with a limited number of customers accounting for a substantial portion of our recent revenues, our subsidiaries’ ability to distribute dividends to us may be subject to restrictions under the laws of their respective jurisdictions, the emergence of additional competing technologies, changes in domestic and foreign laws, regulations and taxes, political and social events in Thailand and China, the volatility of the securities markets, and other risks and uncertainties which are generally set forth under the heading, “Key information - Risk Factors” and elsewhere in our Annual Report on Form 20-F filed on April 21, 2026 (the “Annual Report”). Should any of these risks or uncertainties materialize, or should the underlying assumptions about our business and the commercial markets in which we operate prove incorrect, actual results may vary materially from those described as anticipated, estimated or expected in the Annual Report.

All forward-looking statements included herein attributable to us or other parties or any person acting on our behalf, including statements regarding the potential impact, which we expect the overall impact on the Company to remain limited, primarily affecting fuel and vehicle operating costs, with no material disruption expected to our operations or ability to provide services to customers, are expressly qualified in their entirety by the cautionary statements contained or referred to in this section.
