Additional Information and Where to Find It

In connection with the proposed Business Combination, GigCapital5 filed with the Securities and Exchange Commission (the “SEC”) a registration statement on Form S-4 (together with all amendment to such registration statement, the “Registration Statement”), which includes a preliminary proxy statement/prospectus (the “BCA Proxy Statement”) to be distributed to holders of GigCapital5 Common Stock in connection with GigCapital5’s solicitation of proxies for the vote by GigCapital5’s stockholders with respect to the Business Combination and the other matters as described in the Registration Statement and a prospectus relating to the offer of the securities to be issued to the stockholders of QT Imaging in connection with the Business Combination. After the Registration Statement has been filed and declared effective, GigCapital will mail a definitive BCA Proxy Statement, when available, to its stockholders. Investors and security holders and other interested parties are urged to read the BCA Proxy Statement, any amendments thereto and any other documents filed with the SEC carefully and in their entirety when they become available because they will contain important information about GigCapital5, QT Imaging and the proposed Business Combination. Such persons can also read GigCapital5’s Annual Report on Form 10-K and Current Reports on Form 8-K for more information on the security holdings of its officers and directors and their respective interests as security holders in the consummation of the Transactions described in this Current Report. The BCA Proxy Statement, Registration Statement, the Extension Proxy Statement, and GigCapital5’s other reports can be obtained, without charge, at the SEC’s web site (www.sec.gov) and on GigCapital5’s website at www.gigcapital5.com.
