Forward-Looking Statements
Certain statements included in this Current Report on Form 8-K and the exhibits hereto that
are not historical facts 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. These forward-looking
statements include, but are not limited to, statements regarding GigCapital4s and Targets respective industries, future events, the proposed transactions between GigCapital4, Merger Sub, Target and the Holdings, the estimated or
anticipated future results and benefits of the combined company following the proposed transactions, including the likelihood and ability of the parties to successfully consummate the proposed transactions, future opportunities for the combined
company, and other statements that are not historical facts. These statements are based on various assumptions, whether or not identified herein, and on the current expectations of Targets and GigCapital4s 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 Target and GigCapital4. 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
transactions, 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 transactions
or that the approval of GigCapital4s stockholders is not obtained; failure to realize the anticipated benefits of the proposed transactions; risks relating to the uncertainty of the projected financial information with respect to the Target;
risks related to the rollout of the Targets business and the timing of expected business milestones; the effects of competition on the Targets future business; the amount of redemption requests made by GigCapital4s public
stockholders; the ability of GigCapital4 or the combined company to issue equity or equity-linked securities in connection with the proposed transactions or in the future, and those factors discussed in GigCapital4s final prospectus dated
February 8, 2021 and Annual Report on Form 10-K for the fiscal year ended December 31, 2020, in each case, under the heading Risk Factors, and other documents of GigCapital4 filed, or to
be filed, with the SEC. If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that none of GigCapital4
or Target presently know or that GigCapital4 or Target 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
GigCapital4s and Targets expectations, plans or forecasts of future events and views as of the date of this Current Report on Form 8-K. GigCapital4 and Target anticipate that subsequent events and developments will cause
GigCapital4s and Targets assessments to change. However, while GigCapital4 and Target may elect to update these forward-looking statements at some point in the future, GigCapital4 and Target specifically disclaim any obligation to do so.
These forward-looking statements should not be relied upon as representing GigCapital4s and Targets 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. Certain market data information in this Current Report on Form 8-K is based on the estimates of Target and GigCapital4 management. Target and GigCapital4 obtained the industry, market and competitive position
data used throughout this Current Report on Form 8-K from internal estimates and research as well as from industry publications and research, surveys and studies conducted by third parties. Target and GigCapital4 believe their estimates to be
accurate as of the date of this Current Report on Form 8-K. However, this information may prove to be inaccurate because of the method by which the Target or GigCapital4 obtained some of the data for its estimates or because this information cannot
always be verified due to the limits on the availability and reliability of raw data, the voluntary nature of the data gathering process.
