Bigbear AI SPAC Presentation Deck

Safe Harbor (cont.) USE OF PROJECTIONS This Presentation contains projected financial information with respect to BigBear.ai, namely the Company's projected revenue, products sold, gross profit, Adjusted EBITDA and Adjusted EBITDA margin for 2021-2025. 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 projected financial information are inherently uncertain and are subject to a wide variety of significant business, economic, competitive and other risks and uncertainties that could cause actual results to differ materially from those contained in the projected financial information. See "Forward-Looking Statements" paragraph above. Actual results may differ materially from the results contemplated by the projected financial 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 the results reflected in such projections will be achieved. Neither the independent auditors of GigCapital4 nor the independent registered public accounting firm of the Company audited, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this Presentation and, accordingly, neither of them expressed an opinion or provided any other form of assurance with respect thereto for the purpose of this Presentation. 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 GigCapital4 and the Company's performance. Moreover, actual events are difficult to project and often depend upon factors that are beyond the control of GigCapital4 and the Company and its affiliates. 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, the Company 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. IMPORTANT INFORMATION FOR INVESTORS AND STOCKHOLDERS In connection with the proposed Business Combination, GigCapital4 intends to file a proxy statement with the SEC. The definitive proxy statement and other relevant documents will be sent or given to the stockholders of GigCapital4 and will contain important information about the proposed Business Combination and related matters. GigCapital4 stockholders and other interested persons are advised to read, when available, the proxy statement in connection with GigCapital4's solicitation of proxies for the meeting of stockholders to be held to approve the Business Combination because the proxy statement will contain important information about the proposed Business Combination. When available, the definitive proxy statement will be mailed to GigCapital4 stockholders 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, without charge, once available, at the SEC's website at www.sec.gov. PARTICIPANTS IN SOLICITATION GigCapital4, the Company and their respective directors, managers and officers may be deemed participants in the solicitation of proxies of stockholders in connection with the proposed Business Combination. GigCapital4 stockholders and other interested persons may obtain, without charge, more detailed information regarding the directors, managers and officers of GigCapital4 in GigCapital4's Registration Statement on Form S-1 initially filed with the SEC on January 22, 2021. Additional information will be available in the definitive proxy statement when it becomes available. USE OF NON-GAAP FINANCIAL MEASURES The financial information and data contained in this Presentation is unaudited and does not conform to Regulation S-X promulgated under the Act. Accordingly, such information and data may not be included in, may be adjusted in or may be presented differently in, any proxy statement to be filed by GigCapital4 with the SEC. Some of the financial information and data contained in this Presentation, such as Adjusted EBITDA and Adjusted EBITDA margin, have not been prepared in accordance with United States generally accepted accounting principles ("GAAP"). GigCapital4 and BigBear.ai believe these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to the Company's financial condition and results of operations. GigCapital4 and BigBear.ai believe that the use of these non-GAAP financial measures provide an additional tool for investors to use in evaluating projected operating results and trends in and in comparing BigBear.ai's financial measures with other similar companies, many of which present similar non-GAAP financial measures to investors. Management 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 the Company'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. In order to compensate for these limitations, management presents non-GAAP financial measures in connection with GAAP results. SEGMENT REPORTING The Company reports its results in two segments: Cyber and Engineering (C&E) and Analytics. Within the segments, the Chief Operating Decision Maker (CODM) evaluates performance and allocates resources based on Segment Gross Profit and Segment Gross Profit Margin, which are calculated by reducing the costs associated with development activities on Firm Fixed Price (FFP) and Time and Material (T&M) contracts from cost of revenue, where the Company retains intellectual property that can be repurposed for future use. Segment Gross Profit and Gross Profit Margin are not calculated on the same basis as Consolidated Gross Profit and Gross Profit Margin. In addition, Segment Gross Profit and Gross Profit Margin for the fiscal year ended December 31, 2020 are presented on a pro forma basis to reflect results of closed acquisitions and include management's estimates of segment results for the period during such fiscal year prior to the adoption of segment reporting. INDUSTRY AND MARKET DATA This Presentation has been prepared by GigCapital4 and BigBear.ai and includes market data and other statistical information from sources believed by GigCapital4 and the Company to be reliable, including independent industry publications, governmental publications or other published independent sources. Some data is also based on the good faith estimates of GigCapital4 and BigBear.ai, which are derived from its review of internal sources as well as the independent sources described above. Although GigCapital4 and the Company believe these sources are reliable, they have not independently verified the information and cannot guarantee its accuracy and completeness.
