Forward-Looking Statements

This communication contains certain forward-looking statements within the meaning of the U.S. federal securities laws. All statements contained in this communication other than statements of historical fact, including, without limitation, statements regarding the Business Combination, and the anticipated benefits and timing thereof, and other statements regarding SPAC’s or Pubco’s future performance, are forward-looking statements.

Forward-looking statements are often identified by the use of words such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “potential,” “predict,” “project,” “should,” “will,” “would,” and similar expressions, but the absence of these words does not mean that a statement is not forward-looking.

These forward-looking statements are based on the current expectations and assumptions of SPAC and, although SPAC believes these forward-looking statements are based on reasonable assumptions at the time they are made, you should be aware that such statements are subject to risks and uncertainties, including those described in Pubco’s registration statement on Form S-4 filed with the SEC in connection with the Business Combination, that could cause actual results to differ materially from those expressed or implied by such forward-looking statements. As you read and consider this communication, you should understand that these statements are not guarantees of future performance or results. You should not place undue reliance on these forward-looking statements.
