Cautionary Note Regarding Forward-Looking Statements

This Current Report includes “forward-looking statements” within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. Any statements contained herein that are not statements of historical fact may be deemed to be forward-looking statements. In addition, any statements that refer to characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. Words such as “expect,” “estimate,” “project,” “budget,” “forecast,” “anticipate,” “intend,” “plan,” “may,” “will,” “could,” “should,” “believes,” “predicts,” “potential,” “continue,” and similar expressions (or their negative) identify certain of these forward-looking statements. These forward-looking statements, include, but are not limited to statements regarding the expected impact of uplisting to the Nasdaq Capital Market and the intentions, beliefs, or current expectations of the Company and its subsidiary Sono Motors GmbH (together, the “companies”). Forward-looking statements involve inherent known and unknown risks, uncertainties and contingencies because they relate to events and depend on circumstances that may or may not occur in the future and could cause the companies’ actual results, performance or achievements to differ materially from those expressed or implied by such forward-looking statements. These risks, uncertainties and assumptions include, but are not limited to, risks, uncertainties and assumptions with respect to: the Company’s ability to uplist to the Nasdaq Capital Market, including meeting the initial and continuous listing requirements; the Company’s ability to satisfy the conditions precedent set forth in its recent securities purchase agreement (“Securities Purchase Agreement”) and exchange agreement (“Exchange Agreement”) entered into with YA II PN, Ltd. (“Yorkville”); the timing of closing the transactions contemplated by the Securities Purchase Agreement and the Exchange Agreement; the impact of the transactions contemplated by the Exchange Agreement and Securities Purchase Agreement on the Company’s operating results; our ability to maintain relationships with creditors, suppliers, service providers, customers, employees and other third parties in light of the performance and credit risks associated with our constrained liquidity position and capital structure; our ability to comply with OTCQB continuing standards; our ability to achieve our stated goals; our strategies, plan, objectives and goals, including, among others, the successful implementation and management of the pivot of our business to exclusively retrofitting and integrating our solar technology onto third party vehicles; our ability to raise the additional funding required beyond the investment from Yorkville to further develop and commercialize our solar technology and business as well as to continue as a going concern. For additional information concerning some of the risks, uncertainties and assumptions that could affect our forward-looking statements, please refer to our filings with the U.S. Securities and Exchange Commission (“SEC”), including our Annual Report on Form 10-K for the year ended December 31, 2024, which are accessible on the SEC’s website at www.sec.gov and on our website at ir.sonomotors.com. Many of these risks and uncertainties relate to factors that are beyond our ability to control or estimate precisely, such as the actions of courts, regulatory authorities and other factors. Readers should therefore not place undue reliance on these statements, particularly not in connection with any contract or investment decision. Except as required by law, the Company assumes no obligation to update any such forward-looking statements.
