On March 1, 2021, Tailwind Acquisition Corp., a Delaware corporation ("Tailwind") announced a proposed business combination (“the Business Combination”) between Tailwind and QOMPLX, Inc., a Delaware Corporation (“QOMPLX”). On March 2, 2021, Jason Crabtree ("Mr. Crabtree"), Chief Executive Officer and Co-founder of QOMPLX, appeared on an interview with CNBC to discuss the Business Combination. Attached as Exhibit 99.1 to this Current Report Form 8-K and incorporated into this Item 7.01 by reference is a transcript of such interview. Also on March 2, 2021, Mr. Crabtree appeared on an interview with Yahoo Finance. Attached as Exhibit 99.2 to this Current Report Form 8-K and incorporated into this Item 7.01 by reference is a transcript of such interview. A copy of Business Combination Agreement (as it may be amended, supplemented or otherwise modified from time to time, the “Business Combination Agreement”) by and among Tailwind, Compass Merger Sub, Inc., a Delaware corporation (“Merger Sub”), and Rationem, LLC, a Delaware limited liability company, in its capacity as the representative of the stockholders of QOMPLX , related to the Business Combination was attached as Exhibit 2.1 to Tailwind's Current Report on From 8-K filed with the Securities Exchange Commission (“SEC”) on March 1, 2021.

The foregoing (including Exhibits 99.1 and 99.2) are being furnished pursuant to Item 7.01 and will not be deemed to be filed for purposes of Section 18 of the Securities and Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise be subject to the liabilities of that section, nor will it be deemed to be incorporated by reference in any filing under the Securities Act or the Exchange Act.

Additional Information

In connection with the Business Combination, Tailwind intends to file with the SEC a Registration Statement, which will include a preliminary prospectus and preliminary proxy statement. Tailwind will mail a definitive proxy statement/final prospectus and other relevant documents to its stockholders. This communication is not a substitute for the Registration Statement, the definitive proxy statement/final prospectus or any other document that Tailwind will send to its stockholders in connection with the Business Combination. Investors and security holders of Tailwind are advised to read, when available, the proxy statement/prospectus in connection with Tailwind’s solicitation of proxies for its extraordinary general meeting of stockholders to be held to approve the Business Combination (and related matters) because the proxy statement/prospectus will contain important information about the Business Combination and the parties to the Business Combination. The definitive proxy statement/final prospectus will be mailed to stockholders of Tailwind as of a record date to be established for voting on the Business Combination. Stockholders will also be able to obtain copies of the proxy statement/prospectus, without charge, once available, at the SEC’s website at www.sec.gov or by directing a request to: 1545 Courtney Avenue, Los Angeles, CA 90046.

Participants in the Solicitation

Tailwind, QOMPLX and their respective directors, executive officers, other members of management, and employees, under SEC rules, may be deemed to be participants in the solicitation of proxies of Tailwind’s stockholders in connection with the Business Combination. Investors and security holders may obtain more detailed information regarding the names and interests in the Business Combination of Tailwind’s directors and officers in Tailwind’s filings with the SEC, including the Registration Statement to be filed with the SEC by Tailwind, which will include the proxy statement of Tailwind for the Business Combination. The names and interests of QOMPLX’s directors and executive officers will also be in the Registration Statement to be filed with the SEC by Tailwind, which will include the proxy statement of Tailwind for the Business Combination.

Forward Looking Statements

Certain statements made herein are not historical facts but are forward-looking statements for purposes of the safe harbor provisions under The 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. These forward-looking statements include, but are not limited to, statements regarding future events, the Business Combination between Tailwind and QOMPLX, the estimated or anticipated future results and benefits of the combined company following the Business Combination, including the likelihood and ability of the parties to successfully consummate the Business Combination, future opportunities for the combined company, and other statements that are not historical facts. These statements are based on the current expectations of Tailwind’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 relied on, by any investor 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 Tailwind and QOMPLX. These statements are subject to a number of risks and uncertainties regarding Tailwind’s businesses and the Business Combination, and actual results may differ materially. These risks and uncertainties include, but are not limited to, general economic, political and business conditions generally and competitive factors impacting the businesses of any of Tailwind, QOMPLX, Sentar and RPC Tyche; the inability of the parties to consummate the Business Combination or the occurrence of any event, change or other circumstances that could give rise to the termination of the Business Combination Agreement; the inability of QOMPLX to consummate a Pipeline Acquisition or the occurrence of any event, change or other circumstances that could give rise to the termination of the transaction agreement for such Pipeline Acquisition; the outcome of any legal proceedings that may be instituted against the parties following the announcement of the Business Combination; the receipt of an unsolicited offer from another party for an alternative business transaction that could interfere with the Business Combination; the risk that the approval of the stockholders of Tailwind or QOMPLX for the potential transaction is not obtained; failure to realize the anticipated benefits of the Business Combination, including as a result of a delay in consummating the potential transaction or difficulty in integrating the businesses of Tailwind, QOMPLX, Sentar and RPC Tyche; the risk that the Business Combination disrupts current plans and operations as a result of the announcement and consummation of the Business Combination; the ability of the combined company to grow and manage growth profitably and retain its key employees; the amount of redemption requests made by Tailwind’s stockholders; the inability to obtain or maintain the listing of the post-acquisition company’s securities on NYSE following the Business Combination; costs related to the Business Combination; inaccuracies for any reason in the estimates of expenses and profitability and the projected financial information (including on a pro forma basis giving effect to the acquisitions of Hyperion Gray, Sentar and RPC Tyche) for QOMPLX; and those factors discussed in Tailwind’s final prospectus relating to its initial public offering, dated September 3, 2020, and other filings with the SEC. There may be additional risks that Tailwind presently does not know or that Tailwind currently believes are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements provide Tailwind’s expectations, plans or forecasts of future events and views as of the date of this communication. Tailwind anticipates that subsequent events and developments will cause Tailwind’s assessments to change. However, while Tailwind may elect to update these forward-looking statements at some point in the future, Tailwind specifically disclaims any obligation to do so. These forward-looking statements should not be relied upon as representing Tailwind’s assessments as of any date subsequent to the date of this communication. Accordingly, undue reliance should not be placed upon the forward-looking statements.
