Forward-Looking Statements

This press release contains forward-looking statements within the meaning of Section 27A of the Securities Act, and Section 21E of the Exchange Act. Forward-looking statements may be identified by the use of words such as “estimate,” “plan,” “project,” “forecast,” “intend,” “will,” “expect,” “anticipate,” “believe,” “seek,” “target” or other 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 estimates and forecasts of other financial and performance metrics, and projections of market opportunity and market share. These statements are based on various assumptions, whether or not identified in this press release, and on the current expectations of management of the Company 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 the Company. These forward-looking statements are subject to a number of risks and uncertainties, including changes in domestic and foreign business, market, financial, political, and legal conditions; the inability of the parties to successfully or timely consummate the proposed business combination, including the risk that any required 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 proposed business combination or that the approval of stockholders is not obtained; failure to realize the anticipated benefits of the proposed business combination; risks relating to the uncertainty of the projected financial information with respect to the Company; risks related to the rollout of BigBear.ai’s business and the timing of expected business milestones; the effects of competition on the Company’s future business; the amount of redemption requests made by GigCapital4’s public stockholders; the ability of GigCapital4 or the combined company to issue equity or equity-linked securities in connection with the proposed business combination or in the future. If any of these risks materialize or the Company’s assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. Additional factors that could cause actual results to differ are discussed under the heading “Risk Factors” and in other sections of GigCapital4’s filings with the SEC, and in GigCapital4’s current and periodic reports filed or furnished from time to time with the SEC. There may be additional risks that neither GigCapital4 nor the Company presently know or that they 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 GigCapital4 and BigBear.ai’s expectations, plans or forecasts of future events and views as of the date of this press release, based on information available to GigCapital4 and BigBear.ai as of the date hereof. GigCapital4 and the Company assume no obligation to update any forward-looking statement, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws. While GigCapital4 and the Company may elect to update these forward-looking statements at some point in the future, GigCapital4 and the Company specifically disclaim any obligation to do so. These forward-looking statements should not be relied upon as representing GigCapital4’s and the Company’s assessments as of any date subsequent to the date of this press release.
