Disclaimer 3 Forward-Looking Statements This document includes “forward looking statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by the use of words such as “forecast,” “intend,” “seek,” “target,” “anticipate,” “believe,” “expect,” “estimate,” “plan,” “outlook,” and “project” and other similar expressions that predict or indicate future events or trends or that are not statements of historical matters. Such forward looking statements include estimated financial information, including without limitation, forecasted revenue and revenue CAGR. Such forward looking statements with respect to revenues, earnings, performance, strategies, prospects and other aspects of the businesses of Genesis Park Acquisition Corp., Redwire or the combined company after completion of the Business Combination are based on current expectations that are subject to risks and uncertainties. A number of factors could cause actual results or outcomes to differ materially from those indicated by such forward looking statements. These factors include, but are not limited to: (1) the occurrence of any event, change or other circumstances that could give rise to the termination of the merger agreement governing the proposed business combination; (2) the inability to complete the transactions contemplated by the merger agreement due to the failure to obtain approval of the shareholders of Genesis Park Acquisition Corp. or other conditions to closing in the merger agreement; (3) the ability to meet NYSE’s listing standards following the consummation of the transactions contemplated by the merger agreement; (4) the risk that the proposed transaction disrupts current plans and operations of Redwire as a result of the announcement and consummation of the transactions described herein; (5) the ability to recognize the anticipated benefits of the proposed business combination, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably, maintain relationships with customers and suppliers and retain its management and key employees; (6) costs related to the proposed business combination; (7) changes in applicable laws or regulations; (8) the possibility that Redwire may be adversely affected by other economic, business, and/or competitive factors; and (9) other risks and uncertainties indicated from time to time in other documents filed or to be filed with the SEC by Genesis Park Acquisition Corp. You are cautioned not to place undue reliance upon any forward-looking statements, which speak only as of the date made. Genesis Park Acquisition Corp. and Redwire undertake no commitment to update or revise the forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required by law. Use of Projections This Presentation contains projected financial information with respect to Redwire. Such projected financial information constitutes forward-looking information, and is for illustrative purposes only and should not be relied upon as necessarily being indicative of future results. The assumptions and estimates underlying such financial forecasts are inherently uncertain and are subject to a wide variety of significant business, economic, competitive and other risks and uncertainties. See “Forward-Looking Statements” above. Actual results may differ materially from the results contemplated by the financial forecast information contained in this Presentation, and the inclusion of such information in this Presentation should not be regarded as a representation by any person that results reflected in such forecasts will be achieved. The performance projections and estimates are subject to the ongoing COVID-19 pandemic, and have the potential to be revised to take into account further adverse effects of the COVID-19 pandemic on the future performance of Genesis Park and Redwire. Projected returns and estimates are based on an assumption that public health, economic, market, and other conditions will improve; however, there can be no assurance that such conditions will improve within the time period or to the extent estimated by Genesis Park and Redwire. The full impact of the COVID-19 pandemic on future performance is particularly uncertain and difficult to predict, therefore actual results may vary materially and adversely from the Projections included herein. There are numerous factors related to the markets in general or the implementation of any operational strategy that cannot be fully accounted for with respect to the Projections herein. Any targets or estimates are therefore subject to a number of important risks, qualifications, limitations, and exceptions that could materially and adversely affect Genesis Park and Redwire's performance. Moreover, actual events are difficult to project and often depend upon factors that are beyond the control of Genesis Park and the applicable Company and its affiliates. The performance projections and estimates are subject to the ongoing COVID-19 pandemic, and have the potential to be revised to take into account further adverse effects of the COVID-19 pandemic on the future performance of Genesis Park and the applicable Company. Projected returns and estimates are based on an assumption that public health, economic, market, and other conditions will improve; however, there can be no assurance that such conditions will improve within the time period or to the extent estimated by Genesis Park and Redwire. The full impact of the COVID-19 pandemic on future performance is particularly uncertain and difficult to predict, therefore actual results may vary materially and adversely from the Projections included herein. Trademarks This Presentation contains trademarks, service marks, tradenames and copyrights of Redwire, Genesis Park and other companies, which are the property of their respective owners. The use herein does not imply an affiliation with, or endorsement by, the owners of these service marks, trademarks and tradenames. Third-party logos herein may represent past customers, present customers or may be provided simply for illustrative purposes only. Inclusion of such logos does not necessarily imply affiliation with or endorsement by such firms or businesses. There is no guarantee that either Genesis Park or any of Redwire will work, or continue to work, with any of the firms or businesses whose logos are included herein in the future.

Disclaimer 4 Financial Information; Non-GAAP Financial Terms The financial information and data contained in this Presentation is unaudited and does not conform to Regulation S-X promulgated by the SEC. No independent registered public accounting firm has audited, reviewed, compiled, or performed any procedures with respect to the combined financial information of Redwire for the purpose of inclusion in this Presentation, and accordingly, neither Genesis Park nor any of Redwire expresses an opinion or provides any other form of assurance with respect thereto for the purpose of this Presentation. Accordingly, such information and data may not be included in, may be adjusted in, or may be presented differently in, any registration statement or proxy statement or other report or document to be filed or furnished by Genesis Park with the SEC. Furthermore, some of the projected financial information and data contained in this Presentation, such as Adjusted EBITDA (and related measures), has not been prepared in accordance with United States generally accepted accounting principles (“GAAP”). Redwire and Genesis Park believe these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to Redwire’s financial condition and results of operations. Redwire’s management uses these non-GAAP measures for trend analyses and for budgeting and planning purposes. Redwire and Genesis Park believe that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating projected operating results and trends and in comparing Redwire’s financial measures with other similar companies, many of which present similar non-GAAP financial measures to investors. Management of Redwire does not consider these non-GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these non-GAAP financial measures is that they exclude significant expenses and income that are required by GAAP to be recorded in Redwire’s financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non-GAAP financial measures. You should review the audited financial statements of Redwire and certain businesses acquired by Redwire that will be presented in the Registration Statement to be filed with the SEC, and not rely on any single financial measure to evaluate Redwire’s business. A reconciliation of non-GAAP financial measures in this Presentation to the most directly comparable GAAP financial measures is not included, because, without unreasonable effort, Redwire is unable to predict with reasonable certainty the amount or timing of non-GAAP adjustments that are used to calculate these non-GAAP financial measures. Unless otherwise specified, all Redwire financial information herein is presented on a pro forma basis, including the impact of the acquisitions by Redwire of Adcole Space, Made in Space, Deep Space Systems, Roccor, LoadPath, Oakman Aerospace and Deployable Space Systems. Such financial information assumes that such acquisitions were consummated on January 1st, 2020.
