Forward-Looking Statements

Certain statements included in this press release are not historical facts but are forward-looking statements. Forward-looking statements generally are accompanied by words such as “may,” “will,” “anticipate,” and similar expressions that predict or indicate future events or trends or that are not statements of historical matters, but the absence of these words does not mean that a statement is not forward-looking. These statements are based on various assumptions, whether or not identified in this press release, and on the current expectations of RET’s and Coliseum’s management and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be viewed by any investor as, a guarantee, an assurance, a prediction or a definitive statement of factor probability. Actual events and circumstances are difficult or impossible to predict and may differ from assumptions.

Many actual events and circumstances are beyond the control of Coliseum, RET, and Holdco. Some important factors that could cause actual results to differ materially from those in any forward-looking statements could include changes in domestic and foreign business, market, financial, political and legal conditions; the ability of the parties to successfully consummate the Business Combination; the ability to satisfy the conditions to the consummation of the Business Combination, including the approval of the Business Combination by Coliseum’s shareholders and the satisfaction of the minimum cash condition; the amount of redemption requests made by Coliseum’s public shareholders; the effect of the announcement and pendency of the Business Combination on RET’s business; RET’s ability to manage future growth; Holdco’s ability to meet the listing standards of Nasdaq; the failure to obtain, maintain, adequately protect, or enforce RET’s intellectual property rights; the numerous regulatory and legal requirements that RET will need to comply with to operate its business; the concentrated ownership of Holdco’s stock in RET’s principal stockholders; and the other risks presented elsewhere herein and in the Registration Statement. If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. You should carefully consider the risks and uncertainties described in the “Risk Factors” section of the Registration Statement, along with the risks and uncertainties described in the “Risk Factors” section of Coliseum’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and other documents filed by Coliseum, Holdco, and RET from time to time with the SEC. There may be additional risks that neither Coliseum, Holdco, nor RET presently know or that Coliseum, Holdco, and RET currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements.

You are cautioned not to place undue reliance upon any forward-looking statements. Any forward-looking statement speaks only as of the date on which it was made, based on information available as of the date of this press release, and such information may be inaccurate or incomplete. Coliseum, Holdco, and RET expressly disclaim any obligation or undertaking to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by law. Information regarding performance by, or businesses associated with, RET’s or Holdco’s management team or businesses associated with them is presented for informational purposes only. Past performance by RET’s or Holdco’s management team and its affiliates is not a guarantee of future performance. Therefore, you should not place undue reliance on the historical record of the performance of RET’s or Holdco’s management team or businesses associated with them as indicative of RET’s or Holdco’s future performance of an investment or the returns RET or Holdco will, or is likely to, generate going forward.
