Statements that are not historical in nature, including the words "anticipate," "expect," "suggests," "plan," "believe," "intend," "estimates," "targets," "projects," "should," "could," "would," "may," "will," "forecast" and other similar expressions are intended to identify forward- looking statements. These forward-looking statements include, but are not limited to, statements regarding the benefits and efficiencies of a hybrid concentrated solar solution and achievement of such efficiencies and goals. Forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. Many factors could cause actual future events to differ materially from the forward-looking statements in this presentation, including but not limited to: (i) our financial and business performance, including risk of uncertainty in our financial projections and business metrics and any underlying assumptions thereunder; (ii) changes in our business and strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects and plans; (iii) our ability to execute our business model, including market acceptance of our planned products and services and achieving sufficient production volumes at acceptable quality levels and prices; (iv) our ability to maintain listing on the New York Stock Exchange; (v) our ability to access sources of capital to finance operations, growth and future capital requirements; (vi) our ability to maintain and enhance our products and brand, and to attract and retain customers; (vii) our ability to scale in a cost effective manner; (viii) changes in applicable laws or regulations; (ix) developments and projections relating to our competitors and industry; and (x) our ability to protect our intellectual property. You should carefully consider the foregoing factors and the other risks and uncertainties disclosed in the "Risk Factors" section in Part I, Item 1A in our Annual Report on Form 10-K for the annual period ended December 31, 2022 as supplemented in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2023 and other documents filed by Heliogen from time to time with the Securities and Exchange Commission. 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. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and Heliogen assumes no obligation and does not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise.
