Re: Initial Public Offering

Ladies and Gentlemen:

This letter agreement (this “Letter Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into by and among GigCapital7 Corp., a Cayman Islands exempted company (the “Company”) and Craft Capital Management, LLC, as representative (the “Representative”) of the several underwriters named therein (the “Underwriter”), relating to an underwritten initial public offering (the “Public Offering”), of 25,000,000 units (the “Initial Units”) of the Company, and up to 3,750,000 Units that may be purchased to cover over-allotments, if any (together with the Initial Units, the “Units”), each comprised of one Class A ordinary share of the Company, par value $0.0001 per share (each, a “Class A Ordinary Share” and such shares included in the Units, the “Offering Shares”), and one redeemable warrant (a “Warrant” and the Warrants included in the Units sold, the “Offering Warrants”). Each whole Warrant entitles the holder thereof to purchase one Ordinary Share at a price of $11.50 per share, subject to adjustments provided for in the Warrant Agreement. The Units shall be sold in the Public Offering pursuant to a registration statement on Form S-1 and a prospectus (the “Prospectus”) filed by the Company with the Securities and Exchange Commission (the “Commission”). Certain capitalized terms used herein are defined in paragraph 13 hereof.

In order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the Public Offering and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, GigAcquisitions7 Corp., a Cayman Islands exempted company (the “Sponsor”), and each of the undersigned individuals, being an executive officer, director or director nominee of the Company and signing this Letter Agreement in his or her personal capacity and not on behalf of the Company (each, an “Insider” and collectively, the “Insiders”), hereby agrees with the Company as follows:

1. With respect to shareholder votes and associated conversion rights,

(a) if the Company solicits shareholder approval of a Business Combination via a proxy solicitation, then the undersigned will vote all then outstanding Ordinary Shares beneficially owned by him, her or it in favor of such Business Combination (including any proposals recommended by the Company’s board of directors in connection with such Business Combination); provided, that (i) the undersigned acknowledges and agrees that prior to entering into a Business Combination with a target business that is affiliated with the Sponsor or any Insiders, such transaction must be approved by a majority of the Company’s disinterested independent directors and the Company must obtain an opinion from an independent investment banking firm, or another independent entity that commonly renders valuation opinions on the type of target business the Company is seeking to acquire, that such Business Combination is fair to the Company’s unaffiliated shareholders from a financial point of view, and (ii) neither the Sponsor, nor any Insider, will be entitled to receive or accept a finder’s fee or any other compensation in the event such Insider originates a Business Combination;

(b) the undersigned hereby agrees not to propose for a shareholder approval any amendment to the Amended and Restated Memorandum and Articles of Association that would (i) affect the substance or timing of the Company’s obligation to redeem 100% of the Offering Shares if the Company does not complete a Business Combination within 21 months of the closing of the Public Offering (or such longer period set forth in the Company’s Amended and Restated Memorandum and Articles of Association, as may be amended from time to

time), or (ii) alter its provisions relating to the Company’s pre-Business Combination activity or the related shareholders’ rights prior to the consummation of such Business Combination, unless, in each case, the Company provides the holders of any Offering Shares with the opportunity to redeem their Offering Shares upon the approval of any such amendment. Such redemption must be at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest (which interest shall be net of franchise and income taxes payable by the Company), divided by the number of then outstanding Offering Shares; and

(c) the undersigned will not redeem any Founder Shares beneficially owned by him, her or it in connection with a solicitation for shareholder approval described in either of clauses (a) or (b) above, or sell any such Founder Shares in a tender offer undertaken by the Company in connection with a Business Combination.

2. If the Company fails to consummate a Business Combination within 21 months of the completion of the Public Offering (or such longer period set forth in the Company’s Amended and Restated Memorandum and Articles of Association, as may be amended from time to time), the Sponsor and each Insider will cause the Company to (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten (10) business days thereafter, redeem 100% of the Offering Shares, at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable by the Company and up to $100,000 of interest to pay dissolution expenses), divided by the number of then issued and outstanding Offering Shares, which redemption will completely extinguish all Public Shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Company’s board of directors, liquidate and dissolve, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

3. Each of the undersigned hereby waives any and all right, title, interest or claim of any kind the undersigned may have in the future in or to any distribution of the Trust Account and any remaining assets of the Company as a result of, or arising out of, any contracts or agreements with the Company and will not seek recourse against the Trust Account for any reason whatsoever; provided, that the foregoing waiver shall not apply with respect to liquidating distributions from the Trust Account made in connection with any Offering Shares purchased by the undersigned or its Affiliates during the Public Offering or on the open market after the completion of the Public Offering if the Company fails to complete a Business Combination within 21 months of the closing of the Public Offering (or such longer period set forth in the Company’s Amended and Restated Memorandum and Articles of Association, as may be amended from time to time). Each of the undersigned acknowledges and agrees that there will be no distribution from the Trust Account with respect to any of the Offering Warrants, all rights of which will terminate upon the Company’s liquidation.

4. In order to minimize potential conflicts of interest that may arise from multiple corporate affiliations,

(a) each of the undersigned shall present to the Company for its consideration, prior to presentation to any other entity, any target business in the technology, media, and telecommunications, artificial intelligence and machine learning, cybersecurity, medical technology and medical equipment, semiconductors and sustainable industries that has a fair market value of at least 80% of the assets held in the Trust Account (excluding any taxes payable on interest earned), subject to any pre-existing fiduciary or contractual obligations the undersigned might have; and

(b) each of the undersigned hereby acknowledges and agrees that (i) the Underwriters and the Company may be irreparably injured in the event of a breach of any of the obligations contained in this Letter Agreement, (ii) monetary damages may not be an adequate remedy for such breach, and (iii) the non-breaching party shall be entitled to injunctive relief, in addition to any other remedy that such party may have in law or in equity, in the event of such breach.

5. None of the undersigned or any of their Affiliates will be entitled to receive, and none of them may accept, any compensation or other cash payment prior to, or for services rendered in order to effectuate, the consummation of the Business Combination, except for the following:

(a) GigManagement, LLC, a Delaware limited liability company and an affiliate of the Sponsor, may receive compensation for office space, utilities, secretarial and administrative services, as provided for under that certain Administrative Services Agreement, dated as of [X], 2024, between the Company and GigManagement, LLC;

(b) The Chief Financial Officer of the Company will receive monthly payments of $20,000 per month; and

(c) any of the undersigned and their Affiliates may receive reimbursement of out-of-pocket expenses incurred by them in connection with certain activities on behalf of the Company, such as identifying and investigating possible business targets and business combinations, as well as advisory fees to directors pertaining to board committee service and extraordinary administrative and analytical services, and repayment upon consummation of a Business Combination of any loans which may be made by them or by their Affiliates to finance transaction costs in connection with an intended Business Combination. While the terms of any such loans have not been determined nor have any written agreements been executed with respect thereto, it is acknowledged and agreed that up to $1,500,000 of any such loans may be convertible into warrants of the post-business combination entity at a price of $1.00 per warrant at the option of the lender.

6. In the event that the Company receives either payment of a termination fee in connection with a Business Combination that is not consummated pursuant to a termination fee provision in a business combination agreement, or a settlement of a potential claim or dispute relating to a business combination (“Termination Assets”), the board of directors will, in fulfillment of their fiduciary duties, be empowered to determine whether to use such funds to pursue a different Business Combination, including by way of funding contributions to the Trust Account for the purpose of amending the Company’s Amended and Restated Memorandum and Articles of Association to allow for a longer period of time to close a Business Combination, or to liquidate or wind up the Company. If the board of directors determines to liquidate and wind up the Company and any Termination Assets are held by the Company outside of the Trust Account, then the undersigned agree that they will not act to cause the board of directors to not distribute such Termination Assets to all holders of Ordinary Shares as of the date of the determination of the board of directors to liquidate and wind up the Company, on a pro rata basis equal to the number of shares held by such holder of Ordinary Shares divided by the total number of Ordinary Shares as of such date.

7. The biographical information of the undersigned individuals previously furnished to the Company and the Representative is true and accurate in all respects, does not omit any material information with respect to the undersigned’s background and contains all of the information required to be disclosed pursuant to Item 401 of Regulation S-K, promulgated under the Securities Act. The undersigned’s FINRA Questionnaire previously furnished to the Company and the Representative is also true and accurate in all respects.

8. Each of the undersigned represents and warrants that (i) he, she or it is not subject to, or a respondent in, any legal action for any injunction, cease-and-desist order, or order or stipulation to desist or refrain from any act or practice relating to the offering of securities in any jurisdiction; (ii) he, she or it has never been convicted of or pleaded guilty to any crime involving any fraud, relating to any financial transaction or handling of funds of another person, or pertaining to any dealings in any securities and he, she or it is not currently a defendant in any such criminal proceeding; and (iii) he, she or it has never been suspended or expelled from membership in any securities or commodities exchange or association, or had a securities or commodities license or registration denied, suspended or revoked.

9. Each of the undersigned agrees that he, she or it shall not Transfer (as defined below): (i) with respect to any Founder Shares or any other Ordinary Shares of the Company (which are not Offering Shares) held by him, her, it or by their Affiliates until the earlier of (i) six months after the completion of a Business Combination or (ii) the date on which, subsequent to a Business Combination, (x) the last sale price of the Ordinary Shares equals or exceeds $11.50 per share (as adjusted for share splits, share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 90 days after a Business Combination, or (y) the Company completes a liquidation, merger, share exchange or other similar transaction that results in all of the Company’s shareholders having the right to exchange their Ordinary Shares for cash, securities or other property, and (ii) with respect to the Private Placement Warrants or any securities underlying the Private

Placement Warrants, until 30 days after the completion of a Business Combination (clauses (i) and (ii) collectively, the “Lock-up Period”). Notwithstanding the foregoing, during the Lock-up Period, Transfers of Founder Shares or any other Ordinary Shares of the Company (which are not Offering Shares), the Private Placement Warrants and Ordinary Shares issued or issuable upon the exercise or conversion of the Private Placement Warrants or the Founder Shares, are permitted to be made (a) amongst Sponsor and its Affiliates, to the Company’s executive officers or directors, or to any Affiliate or family member of any of the Company’s executive officers or directors; (b) in the case of an entity, as a distribution to its partners, shareholders or members upon its liquidation; (c) in the case of an individual, (1) by bona fide gift to such person’s immediate family or to a trust, the beneficiary of which is a member of such person’s immediate family, an Affiliate of such person or to a charitable organization, (2) by virtue of the laws of descent and distribution upon death of such person, (3) pursuant to a qualified domestic relations order; (d) in the case of a trust, by distribution to one or more permissible beneficiaries of such trust; (e) by certain pledges to secure obligations incurred in connection with purchases of the Company’s securities; (f) through private sales or transfers made in connection with the consummation of a Business Combination at prices no greater than the price at which such securities were originally purchased; (g) to the Company for no value for cancellation in connection with the consummation of a Business Combination; (h) in the event of the Company’s liquidation prior to the consummation of a Business Combination; (i) by virtue of the laws of the Cayman Islands, by virtue of Sponsor’s memorandum and articles of association or other constitutional, organizational or formational documents, as amended, upon dissolution of the Sponsor, or by virtue of the constitutional, organizational or formational documents of a subsidiary of Sponsor that holds any securities upon liquidation or dissolution of such subsidiary; or (j) in the event of the Company’s completion of a liquidation, merger, share exchange, reorganization or other similar transaction which results in all of the Company’s shareholders having the right to exchange their Ordinary Shares for cash, securities or other property subsequent to the completion of the Company’s initial Business Combination; provided, that, in case of clauses (a) through (f), these permitted transferees must enter into a written agreement agreeing to be bound by these transfer restrictions and the other terms described in this Letter Agreement to the extent and for the duration that such terms remain in effect at the time of the Transfer.

10. Notwithstanding the foregoing paragraph 9, each of the undersigned agrees that during the period commencing on the effective date of the Underwriting Agreement and ending 180 days after such date, none of them nor any of their Affiliates, may, without the prior written approval of the Underwriters, offer, sell, contract to sell, pledge, or otherwise dispose of, directly or indirectly, or hedge the Company’s Units, Warrants, Ordinary Shares or any other securities convertible into or exchangeable or exercisable for Ordinary Shares, or publicly announce an intention to effect any such transaction. The foregoing sentence shall not apply to (i) the registration of the offer and sale of Units contemplated by the Underwriting Agreement, (ii) the sale of the Units to the Underwriters, and (iii) the forfeiture of any Founder Shares pursuant to their terms or any transfer of Founder Shares to any current or future independent director of the Company (as long as such current or future independent director transferee is subject to this Letter Agreement or executes an agreement substantially identical to the terms of this Letter Agreement, as applicable to directors and officers at the time of such transfer; and as long as, to the extent any Section 16 reporting obligation is triggered as a result of such transfer, any related Section 16 filing includes a practical explanation as to the nature of the transfer).

11. In the event of the liquidation of the Trust Account, Sponsor (the “Indemnitor”) agrees to indemnify and hold harmless the Company against any and all loss, liability, claim, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred in investigating, preparing or defending against any litigation, whether pending or threatened, or any claim whatsoever) to which the Company may become subject as a result of any claim by (i) any third party for services rendered or products sold to the Company, or (ii) a prospective target business with which the Company has entered into an acquisition agreement; provided, however, that such indemnification of the Company by the Indemnitor shall apply only to the extent necessary to ensure that such claims by a third party for services rendered (other than the Company’s independent public accountants) or products sold to the Company or a target do not reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per share of the Offering Shares, or (ii) such lesser amount per share of the Offering Shares held in the Trust Account due to reductions in the value of the trust assets as of the date of the liquidation of the Trust Account, in each case, net of the amount of interest earned on the property in the Trust Account which may be withdrawn to pay taxes, except as to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account (whether or not such agreement is enforceable) and as to any claims under the Company’s indemnity of the Underwriters against certain liabilities, including liabilities under the Securities Act. In the event that any such executed waiver is deemed to be unenforceable against such third party,

the Indemnitor shall not be responsible for any liability as a result of any such third-party claims. The Indemnitor shall have the right to defend against any such claim with counsel of its choice reasonably satisfactory to the Company if, within fifteen (15) days following written receipt of notice of the claim to the Indemnitor, the Indemnitor notifies the Company in writing that it shall undertake such defense.

12. Sponsor has full right and power, without violating any agreement by which it is bound, to enter into this Letter Agreement.
