Redemption Reversals

Shareholders are entitled to submit their public shares for redemption in connection with both the Business Combination Meeting and the Extension Meeting. The redemption deadline in connection with the Meetings is December 19, 2024, at 5:00 p.m. ET. The estimated redemption price per public share is approximately $11.39.

The Company has determined to allow redeeming shareholders to reverse their redemptions in connection with the Meetings through 5:00 p.m. ET on December 20, 2024 without the approval of Coliseum or its sponsor. Shareholders may request to reverse their redemption by contacting the Company’s transfer agent, Continental Stock Transfer & Trust Company, at One State Street, 30th Floor, New York, New York 10004 (e-mail: spacredemptions@continentalstock.com).

Potential Purchases of Public Shares

Certain third-party non-affiliated investors have indicated that they intend to purchase an aggregate of up to approximately 200,000 Public Shares in the open market prior to the Meetings and to not redeem such shares. No definitive agreements have been entered into for any such purchases and we cannot guarantee that such persons will purchase all or any of such indicated shares.

Additional Information about the Business Combination and Where to Find it

As previously disclosed, Coliseum entered into a Business Combination Agreement with Rain Enhancement Technologies, Inc. (“RET”), Rain Enhancement Technologies Holdco, Inc. (“Holdco”), and the other parties thereto, dated June 25, 2024, as subsequently amended on August 22, 2024, which provides that, subject to the satisfaction or waiver of the conditions therein, Coliseum will complete the business combination between the Company and Rain Enhancement Technologies, Inc. (the “Business Combination"). The Business Combination will be submitted to shareholders of Coliseum for their consideration. The Registration Statement on Form S-4 (File No. 333-283425) (as amended, the “Registration Statement”) filed by RET and Holdco, which was declared effective by the Securities and Exchange Commission (“SEC”) on December 10, 2024, includes a proxy statement/prospectus that is both the proxy statement of Coliseum and a prospectus of Holdco relating to the shares to be issued in connection with the Business Combination (the “Proxy Statement/Prospectus”).

Coliseum, RET, and/or Holdco may also file other relevant documents regarding the Business Combination with the SEC.

The Extension Proxy Statement was mailed to Coliseum’s shareholders of record as of November 26, 2024, the record date established for voting on the Extension. Coliseum may also file other relevant documents regarding the Extension with the SEC. This Current Report on Form 8-K and the exhibit hereto do not contain all the information that should be considered concerning the Extension and is not intended to form the basis of any investment decision or any other decision in respect of the Extension. Before making any voting or investment decision, investors, security holders of Coliseum, and other interested persons are urged to read the Extension Proxy Statement and any amendments or supplements thereto in connection with Coliseum’s solicitation of proxies for its extraordinary meeting of shareholders to be held to approve, among other things, the Extension, because these documents will contain important information about Coliseum and the Extension.

Forward-Looking Statements

Certain statements included in this Current Report on Form 8-K and the exhibit hereto 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 Current Report on Form 8-K or the exhibit hereto, 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 Current Report on Form 8-K, 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.

No Offer or Solicitation

This Current Report on Form 8-K and the exhibit hereto do not constitute an offer to sell or exchange, or the solicitation of an offer to buy or exchange, any securities, or a recommendation to purchase, any securities in any jurisdiction, or the solicitation of any proxy, vote, consent or approval in any jurisdiction with respect to any securities or in connection with the Business Combination or Extension. There shall not be any offer, sale or exchange of any securities of RET, Holdco, or Coliseum in any jurisdiction where, or to any person to whom, such offer, sale or exchange may be unlawful under the laws of the jurisdiction prior to registration or qualification under the securities laws of any such jurisdiction.
