All statements, other than statements of present or historical fact included in this presentation, are forward-looking statements. When used herein, the words "aims", "could," "should," "will," "may," "believe," "anticipate," "intend," "estimate," "expect," "project," "outlook," "guidance" the negative of such terms and other similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. Forward-looking statements are based on management's current expectations and assumptions about future events and are based on currently available information as to the outcome and timing of future events. Except as otherwise required by applicable law, Hyzon disclaims any duty to update any forward-looking statements, all of which are expressly qualified by events or circumstances after the date of this presentation. Hyzon cautions you that forward-looking statements are subject to numerous risks and uncertainties, most of which are difficult to predict and many of which are beyond the control of Hyzon, including, but not limited to, the following: our ability to commercialize our products and strategic plans, including our ability to establish facilities to produce our fuel cells, assemble our vehicles or secure hydrogen supply in appropriate volumes, at competitive costs or with competitive emissions profiles; our ability to effectively compete in the heavy-duty transportation sector, and withstand intense competition and competitive pressures from other companies worldwide in the industries in which we operate; our ability to convert non-binding memoranda of understanding into binding orders or sales (including because of the current or prospective resources of our counterparties) and the ability of our counterparties to make payments on orders; our ability to invest in hydrogen production, distribution, and refueling operations to supply our customers with hydrogen at competitive costs to operate their fuel cell electric vehicles; disruptions to the global supply chain, including as a result of geopolitical events, and shortages of raw materials, and the related impacts on our third party suppliers and assemblers; our ability to maintain the listing of our common stock on the Nasdaq Capital Market; our ability to raise financing in the future; our ability to retain or recruit, or changes required in, our officers, key employees or directors; our ability to protect, defend, or enforce our intellectual property on which we depend; and the impacts of legal proceedings, regulatory disputes, and governmental inquiries. Additional information on potential factors that could affect the financial results of Hyzon and its forward-looking statements is included in the "Risk Factors" section of Hyzon's Annual Report on Form 10-K for the year ended December 31, 2022, Hyzon's Quarterly Report on Form 10-Q for the quarter ended March 31, 2023 and other documents filed by Hyzon from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Hyzon gives no assurances that Hyzon will achieve its expectations as may be described herein. 2
