As previously announced, Seaport Global Acquisition Corp. (“SGAC”) announced a proposed business combination (the “Business Combination”) between SGAC and Redwood Intermediate, LLC (“Redbox”). In connection with the Business Combination, Redbox will hold meetings with investors beginning on September 21, 2021, consisting of a presentation given by Redbox’s management team. A copy of this investor presentation is attached hereto as Exhibits 99.1 and incorporated by reference herein.

IMPORTANT ADDITIONAL INFORMATION AND WHERE TO FIND IT

In connection with the proposed business combination, SGAC has filed a preliminary proxy statement and intends to file a definitive proxy statement with the Securities and Exchange Commission (“SEC”). The preliminary and definitive proxy statements and other relevant documents will be sent or given to the stockholders of SGAC as of the record date established for voting on the proposed business combination and will contain important information about the proposed business combination and related matters. Stockholders of SGAC and other interested persons are advised to read, when available, the preliminary proxy statement and any amendments thereto and, once available, the definitive proxy statement, in connection with SGAC’s solicitation of proxies for the meeting of stockholders to be held to approve, among other things, the proposed business combination because the proxy statement will contain important information about SGAC, Redbox and the proposed business combination. When available, the definitive proxy statement will be mailed to SGAC’s stockholders as of a record date to be established for voting on the proposed business combination. Stockholders will also be able to obtain copies of the proxy statement, without charge, once available, at the SEC’s website at www.sec.gov/ or by directing a request to: Seaport Global Acquisition Corp., 360 Madison Avenue, 20^th Floor, New York, NY 10017, Attention: Secretary, telephone: (212) 616-7700.

This communication does not constitute an offer to sell or the solicitation of an offer to buy any securities or a solicitation of any vote or approval, nor shall there be any sale of any securities in any state or jurisdiction in which such offer, solicitation, or sale would be unlawful prior to registration or qualification under the securities laws of such other jurisdiction.

FORWARD-LOOKING STATEMENTS

This Current Report on Form 8-K includes certain statements that are not historical facts but are forward-looking statements for purposes of the safe harbor provisions under the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements generally are accompanied by words such as “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “should,” “would,” “plan,” “predict,” “potential,” “seem,” “seek,” “future,” “outlook,” and similar expressions that predict or indicate future events or trends or that are not statements of historical matters. All statements, other than statements of present or historical fact included in this Current Report on Form 8-K, regarding SGAC’s proposed business combination with Redbox, SGAC’s ability to consummate the transaction, the benefits of the transaction and the combined company’s future financial performance, as well as the combined company’s strategy, future operations, estimated financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management are forward-looking statements. These statements are based on various assumptions, whether or not identified in this Current Report on Form 8-K, and on the current expectations of the respective management of SGAC and Redbox 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 relied on as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of SGAC or Redbox. Potential risks and uncertainties that could cause the actual results to differ materially from those expressed or implied by forward-looking statements include, but are not limited to, changes in domestic and foreign business, market, financial, political and legal conditions; the inability of the parties to successfully or timely consummate the business combination, including the risk that any regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the combined company or the expected benefits of the business combination or that the approval of the stockholders of SGAC or Redbox is not obtained; failure to realize the anticipated benefits of business combination; risk relating to the uncertainty of the projected financial information with respect to Redbox; the amount of redemption requests made by SGAC’s stockholders; the overall level of consumer demand for Redbox’s products; general economic conditions and other factors affecting consumer confidence, preferences, and behavior; disruption and volatility in the global currency, capital, and credit markets; the financial strength of Redbox’s customers; Redbox’s ability to implement its business and growth strategy; changes in governmental regulation, Redbox’s exposure to litigation claims and other loss contingencies; disruptions and other impacts to Redbox’s business, as a result of the COVID-19 pandemic and government actions and restrictive measures implemented in response, and as a result of the proposed transaction; Redbox’s ability to retain and expand customer relationships; competitive pressures from many sources, including those using other distribution channels, having more experience, larger or more appealing inventory, better financing, and better relationships with those in the physical and streaming movie and television industries; developments in the home video distribution market as newer technologies and distribution channels compete for market share, and Redbox experiences a secular decline in the physical rental market; the impact of decreased quantity and quality of movie content availability for physical and digital distribution due to changes in quantity of new releases by studios, movie content failing to appeal to consumers’ tastes, increased focus on digital sales and rentals, and other general industry-related factors; the termination, non-renewal or renegotiation on materially adverse terms of Redbox’s contracts or relationships with one or more of its significant retailers or studios; Redbox’s inability to obtain licenses to digital movie or television content for home entertainment viewing; Redbox’s reliance upon a number of partners to make its digital service available on their devices; unforeseen costs and potential liability in connection with content Redbox acquires, produces, licenses and/or distributes through its service; the impact of the COVID-19 pandemic on Redbox’s business, results of operations and financial condition, its suppliers and customers and on the global economy; the impact that global climate change trends may have on Redbox and its suppliers and customers; Redbox’s ability to protect patents, trademarks and other intellectual property rights; any breaches of, or interruptions in, SGAC’s information systems; fluctuations in the price, availability and quality of electricity and other raw materials and contracted products as well as foreign currency fluctuations; changes in tax laws and liabilities, tariffs, legal, regulatory, political and economic risks. More information on potential factors that could affect SGAC’s or Redbox’s financial results is included from time to time in SGAC’s public reports filed with the SEC, including its Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K as well as the preliminary and the definitive proxy statements that SGAC intends to file with the SEC in connection with SGAC’s solicitation of proxies for the meeting of stockholders to be held to approve, among other things, the proposed business combination. If any of these risks materialize or SGAC’s or Redbox’s assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that neither SGAC nor Redbox presently know, or that SGAC and Redbox currently believe are immaterial, that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect SGAC’s and Redbox’s expectations, plans or forecasts of future events and views as of the date of this Current Report on Form 8-K. SGAC and Redbox anticipate that subsequent events and developments will cause their assessments to change. However, while SGAC and Redbox may elect to update these forward-looking statements at some point in the future, SGAC and Redbox specifically disclaim any obligation to do so, except as required by law. These forward-looking statements should not be relied upon as representing SGAC’s or Redbox’s assessments as of any date subsequent to the date of this Current Report on Form 8-K. Accordingly, undue reliance should not be placed upon the forward-looking statements.

This Current Report on Form 8-K shall not constitute a solicitation of a proxy, consent or authorization with respect to any securities or in respect of the Business Combination. This Current Report on Form 8-K shall also not constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of securities in any states or jurisdictions in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction.
