THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE EXTENSION PROPOSAL AND, IF PRESENTED, THE ADJOURNMENT PROPOSAL.

The sole purpose of the Extension Proposal is to provide the Company with sufficient time to complete an initial business combination.

The Charter provides that the Company has 18 months from the consummation of the IPO (such date being April 25, 2023), or up to 24 months (such date being October 25, 2023) from the consummation of the IPO at the Company’s election, in two separate three-month extensions from April 25, 2023 subject to satisfaction of certain conditions, including the deposit of up to $2,000,000 ($0.10 per unit in each case) for each three-month extension into the Trust Account, within which to complete an initial business combination. While the Company is currently in discussions regarding various business combination opportunities, the Company’s board of directors (the “Board”) has determined that there may not be sufficient time before April 25, 2023 to complete an initial business combination. Therefore, the Board has determined that it is in the best interests of the Company to extend the date by which the Company has to complete an initial business combination.

In connection with the Extension, public shareholders may elect to redeem their shares for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company, divided by the number of then-issued and outstanding Class A Ordinary Shares, regardless of how such public shareholders vote on the Extension Proposal or if they vote at all. If the Extension is approved by the requisite vote of shareholders, the remaining shareholders will retain their right to redeem their Class A Ordinary Shares upon consummation of the Company’s initial business combination when it is submitted to a vote of the shareholders, subject to any limitations set forth in the Charter, as amended. In addition, public shareholders will be entitled to have their shares redeemed for cash if the Company has not completed an initial business combination by the Extended Date or the Additional Extension Date, as applicable.

Based upon the amount held in the Trust Account as of December 31, 2022, which was $206,946,000, and estimated interest income and taxes post-December 31, 2022, the Company estimates that the per-share price at which public shares may be redeemed from cash held in the Trust Account will be approximately $10.35 at the time of the Extraordinary General Meeting. The closing price of a Class A Ordinary Share on March 10, 2023, was $10.43. The Company cannot assure shareholders that they will be able to sell their Class A Ordinary Shares in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in its securities when such shareholders wish to sell their shares.

Pursuant to the Charter, a public shareholder may request that the Company redeem all or a portion of such public shareholder’s public shares for cash if the Extension Proposal is approved. You will be entitled to receive cash for any public shares to be redeemed only if you:

(1) (a) hold public shares or (b) hold public shares as part of units and elect to separate such units into the underlying public shares and public warrants prior to exercising your redemption rights with respect to the public shares; and

(2) prior to                     , Eastern Time, on                     , 2023 (two business days prior to the vote at the Extraordinary General Meeting), (a) submit a written request to Continental Stock Transfer & Trust Company, the Company’s transfer agent, that the Company redeem your public shares for cash and (b) deliver your public shares to the transfer agent, physically or electronically through The Depository Trust Company.

Holders of units of the Company must elect to separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares. If holders hold their units in an account at a brokerage firm or bank, holders must notify their broker or bank that they elect to separate the units into the underlying public shares and public warrants, or if a holder holds units registered in its, his or her own name, the holder must contact the transfer agent directly and instruct it to do so. Public shareholders may elect to redeem all or a portion of their public shares even if they vote for the Extension Proposal.

If the Extension is not approved and the Company does not consummate an initial business combination by April 25, 2023 (or by October 25, 2023 at the election of the Company in two separate three-month extensions

subject to satisfaction of certain conditions, including the deposit of up to $2,000,000 ($0.10 per unit in each case) for each three-month extension, into the Trust Account), the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter subject to lawfully available funds therefor, redeem 100% of the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company (less taxes payable, and up to $100,000 of interest to pay dissolution expenses), divided by the total number of then-issued and outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the Board, liquidate and dissolve, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and other requirements of applicable law. There will be no redemption rights or liquidating distributions with respect to the Company’s warrants, which will expire worthless if the Company fails to complete the Company’s initial business combination by April 25, 2023, or by the applicable deadline as may be extended.

Approval of the Extension Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of the holders of at least two-thirds of the Class A Ordinary Shares and Class B ordinary shares, par value $0.0001 per share, of the Company (“Class B Ordinary Shares” and, together with the Class A Ordinary Shares, the “Ordinary Shares”) who, being present in person (including virtually) or represented by proxy and entitled to vote thereon and who do so in person or by proxy at the Extraordinary General Meeting. Ordinary Shares that are present virtually during the Extraordinary General Meeting constitute Ordinary Shares represented “in person.”

The Adjournment Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of the Ordinary Shares who, being present in person (including virtually) or represented by proxy and entitled to vote thereon and who do so in person or by proxy at the Extraordinary General Meeting.

The Board has fixed the close of business on March 7, 2023, as the record date for the Extraordinary General Meeting. Only shareholders of record on March 7, 2023, are entitled to notice of and to vote at the Extraordinary General Meeting or any postponement or adjournment thereof. Further information regarding voting rights and the matters to be voted upon is presented in the accompanying proxy statement.

You are not being asked to vote on an initial business combination at this time. If the Extension is implemented and you do not elect to redeem your public shares in connection with the Extension, you will retain the right to vote on an initial business combination if and when such transaction is submitted to shareholders and the right to redeem your public shares for cash from the Trust Account in the event a proposed initial business combination is approved and completed or the Company has not consummated an initial business combination by the Extended Date or the Additional Extension Date, as applicable. If an initial business combination is not consummated by the Extended Date or the Additional Extension Date, as applicable, assuming the Extension is implemented, and the Company does not obtain an additional extension, the Company will redeem its public shares.

All GTAC shareholders are cordially invited to attend the Extraordinary General Meeting via the Internet at https://www.cstproxy.com/gtac/2023. To ensure your representation at the Extraordinary General Meeting, however, you are urged to complete, sign, date and return your proxy card as soon as possible. If your shares are held in an account at a brokerage firm or bank, you must instruct your broker or bank on how to vote your shares. You may revoke your proxy card at any time prior to the Extraordinary General Meeting.

A shareholder’s failure to vote in person or by proxy will not be counted towards the number of Ordinary Shares required to validly establish a quorum. Abstentions and broker non-votes will be counted in connection with the determination of whether a valid quorum is established but will have no effect on the outcome of any of the Proposals.

YOUR VOTE IS IMPORTANT. Please sign, date and return your proxy card as soon as possible. You are requested to carefully read the proxy statement and accompanying Notice of Extraordinary General Meeting for a more complete statement of matters to be considered at the Extraordinary General Meeting.

If you have any questions or need assistance voting your ordinary shares, please contact Morrow Sodali LLC, the Company’s proxy solicitor, by calling (800) 662-5200, or banks and brokers can call collect at (203) 658-9400, or by emailing GTAC.info@investor.morrowsodali.com.

Approval of the Extension Proposal is a condition to the implementation of the Extension. In addition, the Company will not proceed with the Extension if the number of redemptions of the Company’s public shares causes the Company to have less than $5,000,001 of net tangible assets following approval of the Extension.

Approval of the Extension Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of the holders of at least two-thirds of the Class A Ordinary Shares and Class B ordinary shares, par value $0.0001 per share, of the Company (“Class B Ordinary Shares” and together with the Class A Ordinary Shares, the “Ordinary Shares”) who, being present in person (including virtually) or by proxy and entitled to vote thereon and who do so in person or by proxy at the Extraordinary General Meeting. Ordinary Shares that are present virtually during the Extraordinary General Meeting constitute Ordinary Shares represented “in person.”

Approval of the Adjournment Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of the Ordinary Shares who, being present in person (including virtually) or represented by proxy and entitled to vote thereon and who vote at the Extraordinary General Meeting.

In connection with the Extension, public shareholders may elect to redeem their shares for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes, divided by the number of then-issued and outstanding Class A Ordinary Shares, regardless of how such public shareholders vote on the Extension Proposal, or if they vote at all. If the Extension is approved by the requisite vote of shareholders, the remaining shareholders will retain their right to redeem their Class A Ordinary Shares upon consummation of the Company’s initial business combination when it is submitted to a vote of the shareholders, subject to any limitations set forth in the Charter. In addition, public shareholders will be entitled to have their shares redeemed for cash if the Company has not completed an initial business combination by the Extended Date or the Additional Extension Date, as applicable.

Pursuant to the Charter, a public shareholder may request that the Company redeem all or a portion of such public shareholder’s public shares for cash if the Extension is approved. You will be entitled to receive cash for any public shares to be redeemed only if you:

(1) (a) hold public shares or (b) hold public shares as part of units and elect to separate such units into the underlying public shares and public warrants prior to exercising your redemption rights with respect to the public shares; and

(2) prior to                     , Eastern Time, on                     , 2023 (two business days prior to the vote at the Extraordinary General Meeting), (a) submit a written request to Continental Stock Transfer & Trust Company, the Company’s transfer agent, that the Company redeem your public shares for cash and (b) deliver your public shares to the transfer agent, physically or electronically through The Depository Trust Company.

Holders of units must elect to separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares. If holders hold their units in an account at a brokerage firm or bank, holders must notify their broker or bank that they elect to separate the units into the underlying public shares and public warrants, or if a holder holds units registered in its, his or her own name, the holder must contact the transfer agent directly and instruct it to do so. Public shareholders may elect to redeem all or a portion of their public shares even if they vote for the Extension Proposal.

If the Extension is not approved and the Company does not consummate an initial business combination by April 25, 2023 (or by October 25, 2023 at the election of the Company in two separate three-month extensions subject to satisfaction of certain conditions, including the deposit of up to $2,000,000 ($0.10 per unit in each case) for each three-month extension, into the Trust Account), the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter subject to lawfully available funds therefor, redeem 100% of the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on

the funds held in the Trust Account and not previously released to the Company (less taxes payable, and up to $100,000 of interest to pay dissolution expenses), divided by the total number of then-issued and outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the Board, liquidate and dissolve, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and other requirements of applicable law.

The Company’s sponsor is Global Technology Acquisition I Sponsor LP, a Cayman Island exempted limited partnership (the “Sponsor”). The Sponsor and the Company’s directors and officers have agreed to waive their respective rights to liquidating distributions from the Trust Account in respect of any Class B Ordinary Shares held by it or them, as applicable, if the Company fails to complete an initial business combination by April 25, 2023, or by the applicable deadline as may be extended, although they will be entitled to liquidating distributions from the Trust Account with respect to any Class A Ordinary Shares they hold if the Company fails to complete its initial business combination by such date. There will be no redemption rights or liquidating distributions with respect to the Company’s 10,500,000 private placement warrants, which will expire worthless if the Company fails to complete its initial business combination by April 25, 2023 or by the applicable deadline as may be extended.

If the Company liquidates, the Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party (other than the Company’s independent auditors) for services rendered or products sold to us, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (1) $10.20 per public share or (2) such lesser amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the trust assets, in each case net of the interest which may be withdrawn to pay taxes, expenses relating to the administration of the Trust Account and limited withdrawals for working capital, 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 and except as to any claims under the Company’s indemnity of the underwriters of the IPO against certain liabilities, including liabilities under the Securities Act of 1933, as amended. The per-share liquidation price for the public shares is anticipated to be approximately $10.35 (based on the amount held in the Trust Account as of December 31, 2022 and estimated interest income and taxes post-December 31, 2022). Nevertheless, the Company cannot assure you that the per share distribution from the Trust Account, if the Company liquidates, will not be less than $10.35 due to unforeseen claims of potential creditors.

If the Extension Proposal is approved, such approval will constitute consent for the Company to (i) remove from the Trust Account an amount (the “Withdrawal Amount”) equal to the number of public shares properly redeemed multiplied by the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company, divided by the number of then outstanding public shares and (ii) deliver to the holders of such redeemed public shares their portion of the Withdrawal Amount. The funds remaining in the Trust Account after the removal of such Withdrawal Amount shall be available for use by the Company to complete an initial business combination on or before the Extended Date or the Additional Extension Date, as applicable. Holders of public shares who do not redeem their public shares now will retain their redemption rights and their ability to vote on an initial business combination through the Extended Date or the Additional Extension Date, if applicable, if the Extension Proposal is approved.

The withdrawal of the Withdrawal Amount will reduce the amount held in the Trust Account, and the amount remaining in the Trust Account may be significantly less than the $206,946,000 that was in the Trust Account as of December 31, 2022. In such an event, the Company may need to obtain additional funds to complete its initial business combination, and there can be no assurance that such funds will be available on terms acceptable to the parties or at all.

Only shareholders of record of the Company as of the close of business on March 7, 2023, are entitled to notice of, and to vote at, the Extraordinary General Meeting or any adjournment or postponement thereof. Each Ordinary Share entitles the holder thereof to one vote. On the record date, there were 25,000,000 Ordinary Shares

issued and outstanding, including 20,000,000 Class A Ordinary Shares and 5,000,000 Class B Ordinary Shares. The Company’s warrants do not have voting rights in connection with the proposals.

Your vote is important. Proxy voting permits shareholders unable to attend the Extraordinary General Meeting in person to vote their shares through a proxy. By appointing a proxy, your shares will be represented and voted in accordance with your instructions. You can vote your shares by completing and returning your proxy card or by completing the voting instruction form provided to you by your broker. Proxy cards that are signed and returned but do not include voting instructions will be voted by the proxy as recommended by the Board. You can change your voting instructions or revoke your proxy at any time prior to the Extraordinary General Meeting by following the instructions included in this proxy statement and on the proxy card.

It is strongly recommended that you complete and return your proxy card before the Extraordinary General Meeting date to ensure that your shares will be represented at the Extraordinary General Meeting. You are urged to review carefully the information contained in the enclosed proxy statement prior to deciding how to vote your shares. If you have any questions or need assistance voting your Ordinary Shares, please contact Morrow Sodali LLC, the Company’s proxy solicitor, by calling (800) 662-5200, or banks and brokers can call collect at (203) 658-9400, or by emailing GTAC.info@investor.morrowsodali.com .

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This proxy statement contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) that are not historical facts, and involve risks and uncertainties that could cause actual results to differ materially from those expected and projected. All statements, other than statements of historical fact included in this proxy statement including, without limitation, regarding the Company’s financial position, business strategy and the plans and objectives of management for future operations, are forward-looking statements. Words such as “expect,” “believe,” “anticipate,” “intend,” “estimate,” “seek” and variations and similar words and expressions are intended to identify such forward-looking statements. Such forward-looking statements relate to future events or future performance, but reflect management’s current beliefs, based on information currently available. A number of factors could cause actual events, performance or results to differ materially from the events, performance and results discussed in the forward-looking statements. For information identifying important factors that could cause actual results to differ materially from those anticipated in the forward-looking statements, please refer to the Risk Factors section of the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 16, 2022, the Company’s subsequent Quarterly Reports on Form 10-Q and elsewhere in the Company’s filings with the SEC. The Company’s securities filings can be accessed on the EDGAR section of the SEC’s website at www.sec.gov. Except as expressly required by applicable securities law, the Company disclaims any intention or obligation to update or revise any forward-looking statements whether as a result of new information, future events or otherwise.

RISK FACTORS

You should consider carefully all of the risks described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on March 16, 2022, the Company’s subsequent Quarterly Reports on Form 10-Q and elsewhere in the Company’s filings with the SEC before making a decision to vote on the proposals described in this proxy statement or to invest in the Company’s securities. Furthermore, if any of the following events occur, the Company’s business, financial condition and operating results may be materially adversely affected or the Company could face liquidation. In that event, the trading price of the Company’s securities could decline, and you could lose all or part of your investment. The risks and uncertainties described in the aforementioned filings and below are not the only ones the Company faces. Additional risks and uncertainties that the Company is unaware of, or that the Company currently believes are not material, may also become important factors that adversely affect the Company’s business, financial condition and operating results or result in the Company’s liquidation.

To mitigate the risk that the Company might be deemed to be an investment company for purposes of the Investment Company Act, the Company expects to, prior to the end of the 24-month period after the effective date of the Company’s registration statement on Form S-1, instruct the trustee to transfer the securities held in the Trust Account and instead to hold the funds in the Trust Account in cash (which may include an interest bearing demand deposit account at a national bank) until the earlier of the consummation of the Company’s initial business combination or the Company’s liquidation. As a result, following sale of securities in the Trust Account, if any, the Company would likely receive minimal interest, if any, on the funds held in the Trust Account, which could reduce the dollar amount the public shareholders would receive upon any redemption or liquidation of the Company.

The funds in the Trust Account have, since the Company’s IPO, been held only in U.S. government treasury obligations with a maturity of 185 days or less or in money market funds investing solely in U.S. government treasury obligations and meeting certain conditions under Rule 2a-7 under the Investment Company Act. While the funds in the Trust Account continue to be invested in such instruments, to mitigate the risk of the Company being deemed to be an unregistered investment company (including under the subjective test of Section 3(a)(1)(A) of the Investment Company Act) and thus subject to regulation under the Investment Company Act, the Company expects to, prior to the 24-month anniversary of the effective date of the Company’s registration statement on Form S-1 (October 20, 2021), instruct the trustee with respect to the Trust Account to transfer the U.S. government treasury obligations or money market funds held in the Trust Account and thereafter, to hold all funds in the Trust Account in cash (which may include an interest bearing demand deposit account at a national bank) until the earlier of the consummation of the Company’s initial business combination or the liquidation of the Company. Following any such sale of the securities held in the Trust Account, the Company would likely receive minimal interest, if any, on the funds held in the Trust Account. However, interest previously earned on the funds held in the Trust Account still may be released to the Company to pay the Company’s taxes, if any, and certain other expenses as permitted. As a result, any decision to transfer the securities held in the Trust Account and thereafter to hold all funds in the Trust Account in cash (which may include an interest bearing demand deposit account at a national bank) could reduce the dollar amount the public shareholders would receive upon any redemption or liquidation of the Company.

In addition, even prior to the 24-month anniversary of the effective date of the Company’s registration statement on Form S-1, the Company may be deemed to be an investment company. The longer that the funds in the Trust Account are held in short-term U.S. government treasury obligations or in money market funds invested exclusively in such securities, even prior to the 24-month anniversary, the greater the risk that the Company may be considered an unregistered investment company under Section 3(a)(1)(A) of the Investment Company Act, in which case the Company may be required to liquidate. If the Company is required to liquidate, the Company’s shareholders will miss the opportunity to benefit from an investment in a target company and the potential appreciation in value of such investment through the Company’s initial business combination. Additionally, if the Company is required to liquidate, there will be no redemption rights or liquidating distributions with respect to

3

the Company’s warrants, which will expire worthless in the event of the Company’s winding up. The risk of being deemed subject to the Investment Company Act may increase the longer the Company holds securities (i.e., the longer past two years the securities are held), and also may increase to the extent the funds in the Trust Account are not held in cash (which may include an interest bearing demand deposit account at a national bank). Accordingly, the Company expects to, prior to the 24-month anniversary of the effective date of the Company’s registration statement on Form S-1, instruct the trustee with respect to the Trust Account to transfer the securities held in the Trust Account and instead hold all funds in the Trust Account in cash (which may include an interest bearing demand deposit account at a national bank), which could further reduce the dollar amount the public shareholders would receive upon any redemption or liquidation of the Company.

The Company’s cash and cash equivalents could be adversely affected if the financial institutions in which it holds its cash and cash equivalents fail.

The Company regularly maintains cash balances at third-party financial institutions, including Silicon Valley Bank, in excess of the Federal Deposit Insurance Corporation insurance limit. On March 10, 2023, the California Department of Financial Protection and Innovation closed Silicon Valley Bank and appointed Federal Deposit Insurance Corporation as receiver, and as a result the Company did not have access to its invested cash or cash equivalents that were not part of the Company’s Trust Account. Although the lack of access to funds with Silicon Valley Bank has been resolved, it is possible that another failure of a depository institution could further impact the Company’s access to its invested cash or cash equivalents and could adversely impact the Company’s operating liquidity and financial performance.

QUESTIONS AND ANSWERS ABOUT THE EXTRAORDINARY GENERAL MEETING

These Questions and Answers are only summaries of the matters they discuss. They do not contain all of the information that may be important to you. You should read carefully the entire document, including any annexes to this proxy statement.

Why am I receiving this proxy statement?

This proxy statement and the enclosed proxy card are being sent to you in connection with the solicitation of proxies by the Company’s Board for use at the Extraordinary General Meeting to be held in person or virtually on                     , 2023, or at any adjournments or postponement thereof. This proxy statement summarizes the information that you need to make an informed decision on the proposals to be considered at the Extraordinary General Meeting.

GTAC is a blank check company incorporated on February 9, 2021 as a Cayman Islands exempted company for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (an “initial business combination”).

In February 2021, the Sponsor paid $25,000, or approximately $0.004 per share, to cover certain of the Company’s offering and formation costs in consideration of 6,468,750 Class B Ordinary Shares, par value $0.0001. On June 30, 2021, the Sponsor surrendered 2,156,250 Class B Ordinary Shares for no consideration, resulting in 4,312,500 shares outstanding of which 562,500 were subject to forfeiture in the event the underwriters’ over-allotment option is not exercised. On October 20, 2021, the Company’s Board approved a 1.16666667 for 1 share dividend for each Class B Ordinary Share outstanding, resulting in 5,031,250 Class B Ordinary Shares outstanding of which 656,250 were subject to forfeiture in the event the underwriters’ over-allotment option was not exercised. As a result of the underwriters’ election to partially exercise their over-allotment option, on December 5, 2021, 31,250 Class B ordinary shares were forfeited, resulting in an aggregate of 5,000,000 Class B Ordinary Shares issued and outstanding. Prior to the initial investment in the company of $25,000 by the Sponsor, the company had no assets, tangible or intangible. The per share price of the Class B Ordinary Shares was determined by dividing the amount contributed to the company by the number of Class B Ordinary Shares issued. On July 11, 2021, the Sponsor transferred 40,000 Class B Ordinary Shares to each of the Company’s independent directors, other than Michael Zeisser, at their original purchase price.

On October 25, 2021, the Company consummated its initial public offering (“IPO”) of 20,000,000 units, which included the partial exercise of the underwriters’ option to purchase an additional 2,500,000 units, at $10.00 per unit. Each unit consists of one Class A ordinary share, par value $0.0001 per share, of the Company (“Class A Ordinary Shares” or “public shares”) and one-half of one redeemable warrant to purchase one Class A Ordinary Share. Simultaneously with the consummation of the IPO, GTAC completed the private placement of 10,500,000 private placement warrants (the “Private Placement” and collectively the “Private Placement Warrants”) at a purchase price of $1.00 per Private Placement Warrant to the Sponsor, generating gross proceeds to the Company of $10,500,000. Following the closing of the IPO and the Private Placement, a total of $204,000,000 of the net proceeds from its IPO and the Private Placement were placed in a trust account at JPMorgan Chase Bank, N.A. (the “Trust Account”) with Continental Stock Transfer & Trust Company (“Continental”) acting as trustee. The Company’s charter provides for the return of the IPO proceeds held in the Trust Account to the holders of public shares if the Company does not complete the Company’s initial business combination by April 25, 2023 (or by October 25, 2023 at the election of the Company in two separate three-month extensions subject to satisfaction of certain conditions, including the deposit of up to $2,000,000 ($0.10 per unit in each case) for each three-month extension, into the Trust Account).

While the Company is currently in discussions regarding various business combination opportunities, the Board has determined that there may not be sufficient time before April 25, 2023, or by the applicable deadline as may be extended, to complete an initial business combination. Therefore, the Board has determined that it is in

5

the best interests of the Company’s shareholders to extend the date by which the Company has to complete an initial business combination to the Extended Date or up to the Additional Extension Date, if the Company has entered into a definitive business combination agreement, in order that the Company’s shareholders are given the chance to participate in an investment opportunity.

What is being voted on?

You are being asked to vote on the following proposals:

(1) A proposal, by special resolution, to amend and restate the Company’s Amended and Restated Memorandum and Articles of Association (the “Charter”) pursuant to an amended and restated Charter in the form set forth in Annex A of the accompanying proxy statement to extend the date by which the Company must (a) consummate an initial business combination, (b) cease its operations except for the purpose of winding up if it fails to complete such initial business combination, and (c) redeem all of the Class A Ordinary Shares included as part of the units sold in the IPO, from April 25, 2023 to April 25, 2024 (the “Extended Date,”) or to October 25, 2024 (the “Additional Extension Date”) at the election of the Company in two separate three-month extensions subject to satisfaction of certain conditions, including the deposit of up to $2,000,000 ($0.10 per unit in each case) for each three-month extension, into the trust account established in connection with the IPO (the “Trust Account”) (the “Extension” and such proposal, the “Extension Proposal”); and

(2) A proposal, by ordinary resolution, to approve the adjournment of the Extraordinary General Meeting to a later date or dates, if necessary or convenient, to permit further solicitation and vote of proxies in the event that there are insufficient votes for, or otherwise in connection with, the approval of the Extension Proposal (the “Adjournment Proposal”), which will only be presented at the Extraordinary General Meeting if, based on the tabulated votes, there are not sufficient votes at the time of the Extraordinary General Meeting to approve the Extension Proposal, in which case the Adjournment Proposal will be the only proposal presented at the Extraordinary General Meeting.

You are not being asked to vote on an initial business combination at this time. If the Extension is implemented and you do not elect to redeem your public shares, you will retain the right to vote on the Company’s initial business combination if and when it is submitted to shareholders and the right to redeem your public shares for cash in the event an initial business combination is approved and completed or the Company has not consummated an initial business combination by the Extended Date or the Additional Extension Date, as applicable.

What is the effect of giving a proxy?

Proxies are solicited by and on behalf of the Board.                          and                          have been designated as proxies by the Board. When proxies are properly dated, executed and returned, the shares represented by such proxies will be voted at the Extraordinary General Meeting in accordance with the instructions of the shareholder. If no specific instructions are given, however, the shares will be voted in accordance with the recommendations of the Board as described below. If any matters not described in this proxy statement are properly presented at the Extraordinary General Meeting, the proxy holders will use their own judgment to determine how to vote the shares. If the Extraordinary General Meeting is adjourned, the proxy holders can vote the shares on the new Extraordinary General Meeting date as well, unless you have properly revoked your proxy instructions, as described elsewhere herein.

Can I attend the Extraordinary General Meeting?

The Extraordinary General Meeting will be held at                     , Eastern Time, on                     , 2023, at the offices of Latham & Watkins LLP, located at 1271 6th Ave, New York, New York 10020, or virtually via live webcast. You will be able to attend the Extraordinary General Meeting online, vote and submit your questions

6

during the Extraordinary General Meeting by visiting https://www.cstproxy.com/gtac/2023. The Extraordinary General Meeting will comply with the meeting rules of conduct. The rules of conduct will be posted on the virtual meeting web portal. The Company encourages you to access the Extraordinary General Meeting webcast prior to the start time. Online check-in will begin fifteen minutes prior to the start time of the Extraordinary General Meeting, and you should allow ample time for the check-in procedures. While shareholders are encouraged to attend the meeting virtually, you will be permitted to attend the Extraordinary General Meeting in person at the offices of Latham & Watkins LLP. You may submit your proxy by completing, signing, dating and returning the enclosed proxy card in the accompanying pre-addressed postage-paid envelope. If you hold your shares in “street name,” which means your shares are held of record by a broker, bank or nominee, you should contact your broker, bank or nominee to ensure that votes related to the shares you beneficially own are properly counted. In this regard, you must provide the broker, bank or nominee with instructions on how to vote your shares.

Why should I vote to approve the Extension?

The Board believes shareholders will benefit from the Company consummating an initial business combination and is proposing the Extension to extend the date by which the Company has to complete an initial business combination until the Extended Date, and up until the Additional Extension Date if applicable. The Extension would give the Company the opportunity to complete its initial business combination.

The Charter currently provides that if the Company does not complete an initial business combination by April 25, 2023, or by October 25, 2023 at the election of the Company in two separate three-month extensions subject to satisfaction of certain conditions, including the deposit of up to $2,000,000 ($0.10 per unit in each case) for each three-month extension, into the Trust Account, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter subject to lawfully available funds therefor, redeem 100% of the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company (less taxes payable, and up to $100,000 of interest to pay dissolution expenses) divided by the total number of then-issued and outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the Board, liquidate and dissolve, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and other requirements of applicable law.

The Company believes that the provisions of the Charter described in the preceding paragraph were included to protect the Company’s shareholders from having to sustain their investments for an unreasonably long period if the Company failed to find a suitable initial business combination in the timeframe contemplated by the Charter. The Company also believes, however, that given the Company’s expenditure of time, effort and money on pursuing an initial business combination and the Company’s belief that an initial business combination offers an attractive investment for the Company’s shareholders, the Extension is warranted.

In connection with the Extension, public shareholders may elect to redeem their shares for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes, divided by the number of then-issued and outstanding Class A Ordinary Shares, regardless of how such public shareholders vote on the Extension Proposal, or if they vote at all. The Company will not proceed with the Extension if redemptions of public shares cause the Company to have less than $5,000,001 of net tangible assets following approval of the Extension Proposal.

Liquidation of the Trust Account is a fundamental obligation of the Company to the public shareholders and the Company is not proposing and will not propose to change that obligation to the public shareholders. If

7

holders of public shares do not elect to redeem their public shares, such holders shall retain redemption rights in connection with an initial business combination. Assuming the Extension is approved, the Company will have until the Extended Date or the Additional Extension Date, as applicable, to complete an initial business combination, unless the Company obtains any additional extension.

The Board recommends that you vote in favor of the Extension Proposal, but expresses no opinion as to whether you should redeem your public shares.

How do the Company insiders intend to vote their shares?

The Sponsor, the Company’s directors, officers and initial shareholders and their permitted transferees (collectively, the “Initial Shareholders”) are expected to vote any Class A Ordinary Shares and Class B Ordinary Shares (together, the “Ordinary Shares”) over which they have voting control in favor of the Extension Proposal and, if presented, the Adjournment Proposal.

The Initial Shareholders are not entitled to redeem any Ordinary Shares held by them. On the record date, the Initial Shareholders beneficially owned and were entitled to vote 5,000,000 Ordinary Shares, which represents 20% of the Company’s issued and outstanding Ordinary Shares.

Subject to applicable securities laws (including with respect to material nonpublic information), the Sponsor, the Company’s directors, officers, advisors or any of their respective affiliates may (i) purchase public shares from institutional and other investors (including those who vote, or indicate an intention to vote, against any of the proposals presented at the Extraordinary General Meeting, or elect to redeem, or indicate an intention to redeem, public shares), (ii) enter into transactions with such investors and others to provide them with incentives to not redeem their public shares, or (iii) execute agreements to purchase such public shares from such investors or enter into non-redemption agreements in the future. In the event that the Sponsor, the Company’s directors, officers, advisors or any of their respective affiliates purchase public shares in situations in which the tender offer rules restrictions on purchases would apply, they (a) would purchase the public shares at a price no higher than the price offered through the Company’s redemption process (i.e., approximately $10.35 per share, based on the amounts held in the Trust Account as of December 31, 2022); (b) would represent in writing that such public shares will not be voted in favor of approving the Extension; and (c) would waive in writing any redemption rights with respect to the public shares so purchased.

To the extent any such purchases by the Sponsor, the Company’s directors, officers, advisors or any of their respective affiliates are made in situations in which the tender offer rules restrictions on purchases apply, the Company will disclose in a Current Report on Form 8-K prior to the Extraordinary General Meeting the following: (i) the number of public shares purchased outside of the redemption offer, along with the purchase price(s) for such public shares; (ii) the purpose of any such purchases; (iii) the impact, if any, of the purchases on the likelihood that the Extension will be approved; (iv) the identities of the securityholders who sold to the Sponsor, the Company’s directors, officers, advisors or any of their respective affiliates (if not purchased on the open market) or the nature of the securityholders (e.g., 5% security holders) who sold such public shares; and (v) the number of Ordinary Shares for which the Company has received redemption requests pursuant to its redemption offer.

The purpose of such share purchases and other transactions would be to increase the likelihood of (i) otherwise limiting the number of public shares electing to redeem and (ii) the Company’s net tangible assets (as determined in accordance with Rule 3a51(g)(l) of the Exchange Act) being at least $5,000,001.

If such transactions are effected, the consequence could be to cause the Extension to be effectuated in circumstances where such effectuation could not otherwise occur. Consistent with SEC guidance, purchases of shares by the persons described above would not be permitted to be voted for the Extension at the Extraordinary General Meeting and could decrease the chances that the Extension would be approved. In addition, if such

8

purchases are made, the public “float” of the Company’s securities and the number of beneficial holders of the Company’s securities may be reduced, possibly making it difficult to maintain or obtain the quotation, listing or trading of the Company’s securities on a national securities exchange.

The Company hereby represents that any Company securities purchased by the Sponsor, the Company’s directors, officers, advisors or any of their respective affiliates in situations in which the tender offer rules restrictions on purchases would apply would not be voted in favor of approving the Extension Proposal.

Who is the Company’s Sponsor?

The Company’s sponsor is Global Technology Acquisition I Sponsor LP, a Cayman Island exempted limited partnership. The Sponsor currently owns an aggregate of 4,880,000 Ordinary Shares, all of which are Class B Ordinary Shares. Global Technology Acquisition I Sponsor GP Ltd. is the general partner of the Sponsor and has voting and investment discretion with respect to the Ordinary Shares held of record by the Sponsor. Arnau Porto, Fabrice Grinda and Jeffery Weinstein are the directors of Global Technology Acquisition I Sponsor GP Ltd. Arnau Porto has two votes and Fabrice Grinda and Jeffery Weinstein each have one vote, and the approval of Arnau Porto and either Fabrice Grinda or Jeffery Weinstein is required to approve an action of Global Technology Acquisition I Sponsor GP Ltd.

The Company’s ability to complete an initial business combination with a U.S. target company may be impacted if such initial business combination is subject to U.S. foreign investment regulations and review by a U.S. government entity, such as the Committee on Foreign Investment in the United States (“CFIUS”), and ultimately prohibited.

The Sponsor, Global Technology Acquisition I Sponsor LP, is a Cayman Island exempted limited partnership and is controlled and majority-owned by non-U.S. nationals. In the event the Sponsor is considered a foreign person, however, the Company could also be considered a foreign person and would continue to be considered as such in the future for so long as the Sponsor has the ability to exercise control over the Company for purposes of CFIUS’s regulations. The Company could likewise be considered a foreign person if a foreign investor acquires a significant interest in the Company and is viewed as having the ability to exercise control over the Company. As such, an initial business combination with a U.S. business may be subject to CFIUS review, the scope of which includes controlling investments, as well as certain non-passive, non-controlling investments in sensitive U.S. businesses and certain acquisitions of real estate even with no underlying U.S. business. If the Company’s potential initial business combination with a U.S. business falls within CFIUS’s jurisdiction, the Company may determine that it is required to make a mandatory filing or that it will submit a voluntary filing to CFIUS, or to proceed with the initial business combination without notifying CFIUS and risk CFIUS intervention, before or after closing the initial business combination. CFIUS may decide to delay the initial business combination, impose conditions to mitigate national security concerns with respect to such initial business combination or recommend that the U.S. president block the initial business combination or order the Company to divest all or a portion of a U.S. business of the combined company, which may limit the attractiveness of or prevent the Company from pursuing certain initial business combination opportunities that it believes would otherwise be beneficial to the Company and its shareholders. As a result, the pool of potential targets with which the Company could complete an initial business combination may be impacted, and it may be adversely affected in terms of competing with other special purpose acquisition companies which do not have similar potential foreign ownership issues.

Moreover, the process of government review, whether by the CFIUS or otherwise, could be lengthy and the Company has limited time to complete its initial business combination. If the Company cannot complete its initial business combination by April 25, 2023, or by the applicable deadline as may be extended, or by the Extended Date or the Additional Extension Date, as applicable, if the Extension is approved, or such later date that may be approved by the Company’s shareholders, because the review process extends beyond such timeframe or because the initial business combination is ultimately prohibited by CFIUS or another U.S.

9

government entity, the Company may be required to liquidate. If the Company liquidates, its public shareholders may only receive approximately $10.35 per share (based on the amount held in the Trust Account as of December 31, 2022 and estimated interest income and taxes post-December 31, 2022, and assuming the Extension is not approved), and the Company’s warrants will expire worthless. This will also cause you to lose the investment opportunity in a target company and the chance of realizing future gains on your investment through any price appreciation in the combined company.

What vote is required to approve the Extension Proposal?

Approval of the Extension Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of the holders of at least two-thirds of the Ordinary Shares who, being present in person (including virtually) or represented by proxy and entitled to vote thereon and who do so in person or by proxy at the Extraordinary General Meeting. Ordinary Shares that are present virtually during the Extraordinary General Meeting constitute Ordinary Shares represented “in person.”

What vote is required to approve the Adjournment Proposal?

Approval of the Adjournment Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of the Ordinary Shares who, being present in person (including virtually) or represented or by proxy and entitled to vote thereon and who do so in person or by proxy at the Extraordinary General Meeting.

What if I want to vote against or don’t want to vote for any of the proposals?

If you do not want any of the proposals to be approved, you must abstain, not vote or vote against such proposal. A shareholder’s failure to vote by proxy or to vote in person at the Extraordinary General Meeting will not be counted towards the number of Ordinary Shares required to validly establish a quorum. Abstentions will be counted in connection with the determination of whether a valid quorum is established.

What happens if the Extension Proposal is not approved?

If the Extension Proposal is not approved and the Company does not consummate an initial business combination by April 25, 2023, or by the applicable deadline as may be extended, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter subject to lawfully available funds therefor, redeem 100% of the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company (less taxes payable, and up to $100,000 of interest to pay dissolution expenses), divided by the total number of then-issued and outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the Board, liquidate and dissolve, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and other requirements of applicable law.

The Initial Shareholders have agreed to waive their respective rights to liquidating distributions from the Trust Account in respect of any Class B Ordinary Shares held by it or them, as applicable, if the Company fails to complete an initial business combination by April 25, 2023, or by the applicable deadline as may be extended, although they will be entitled to liquidating distributions from the Trust Account with respect to any Class A Ordinary Shares they hold if the Company fails to complete its initial business combination by such date. There will be no redemption rights or liquidating distributions with respect to the Company’s warrants, which will expire worthless if the Company fails to complete its initial business combination by April 25, 2023 or by the applicable deadline as may be extended. The Company will pay the costs of liquidation from its remaining assets outside of the Trust Account.

10

If the Extension is approved, what happens next?

The Company is continuing its efforts to complete its initial business combination. The Company is seeking approval of the Extension because the Company may not be able to complete an initial business combination prior to April 25, 2023, or by the applicable deadline as may be extended. If the Extension is approved, the Company expects to continue evaluating business combination opportunities in pursuit of entering into a business combination agreement and seeking shareholder approval of an initial business combination. If shareholders approve an initial business combination, the Company expects to consummate such initial business combination as soon as possible following shareholder approval and satisfaction of the other conditions to the consummation of such initial business combination.

Upon approval of the Extension Proposal by a special resolution under Cayman Islands law, being the affirmative vote of the holders of at least two-thirds of the Ordinary Shares present in person (including virtually) or represented by proxy and entitled to vote thereon and who do so at the Extraordinary General Meeting, the Company will file an amended and restated Charter with the Cayman Islands Registrar of Companies (the “Cayman Registrar”) in the form attached as Annex A hereto. The Company will remain a reporting company under the Exchange Act, and its units, Class A Ordinary Shares and public warrants will remain publicly traded.

If the Extension is approved, any removal of any Withdrawal Amount (defined as an amount equal to the number of public shares properly redeemed multiplied by the aggregate amount then on deposit in the Trust Account), including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes or fund the Company’s working capital requirements, from the Trust Account will reduce the amount remaining in the Trust Account and increase the percentage interest of Ordinary Shares held by the Sponsor through the Class B Ordinary Shares. The Company will not proceed with the Extension if redemptions of public shares cause the Company to have less than $5,000,001 of net tangible assets following approval of the Extension.

If the Extension is approved, the Sponsor will continue to have the right to receive payments from the Company of $10,000 per month for office space, administrative and support services until the earlier of the Company’s consummation of an initial business combination or the Company’s liquidation pursuant to the Administrative Services Agreement, dated as of October 20, 2021, by and between the Company and the Sponsor (the “Administrative Services Agreement”).

Where will I be able to find the voting results of the Extraordinary General Meeting?

The Company will announce preliminary voting results at the Extraordinary General Meeting. The Company will also disclose voting results on a Current Report on Form 8-K that the Company will file with the SEC within four business days after the Extraordinary General Meeting. If final voting results are not available to the Company in time to file a Current Report on Form 8-K within four business days after the Extraordinary General Meeting, the Company will file a Current Report on Form 8-K to publish preliminary results and will provide the final results in an amendment to such Current Report on Form 8-K as soon as they become available.

Would I still be able to exercise my redemption rights in connection with a vote to approve a proposed initial business combination?

Yes. Assuming you are a shareholder as of the record date for voting on a proposed initial business combination, you will be able to vote on a proposed initial business combination if and when it is submitted to shareholders. If you disagree with an initial business combination, you will retain your right to redeem your public shares upon consummation of such initial business combination, subject to any limitations set forth in the Company’s Charter.

11

How do I change my vote?

Shareholders may send a later-dated, signed proxy card to the Company at 19 W 24th Street, 10th Floor, New York, New York 10010, attn.: Chief Executive Officer, so that it is received prior to the vote at the Extraordinary General Meeting (which is scheduled to take place on                     , 2023). Shareholders also may revoke their proxy by sending a notice of revocation to the Company’s Chief Executive Officer, which must be received prior to the vote at the Extraordinary General Meeting, or by attending the Extraordinary General meeting, revoking their proxy and voting in person. However, if your shares are held in “street name” by your broker, bank or another nominee, you must contact your broker, bank or other nominee to change your vote.

How are votes counted?

Votes will be counted by the inspector of election appointed for the meeting, who will separately count “FOR” and “AGAINST” votes, for each of the proposals. A shareholder’s failure to vote by proxy or to vote in person at the meeting will not be counted towards the number of Ordinary Shares required to validly establish a quorum. Abstentions and broker non-votes will be counted in connection with the determination of whether a valid quorum is established but will have no effect on the outcome on any of the Proposals.

If my shares are held in “street name,” will my broker automatically vote them for me?

If you do not give instructions to your broker, your broker can vote your shares with respect to “discretionary” items, but not with respect to “non-discretionary” items. The Company believes that each of the proposals are “non-discretionary” items.

Your broker can vote your shares with respect to “non-discretionary” items only if you provide instructions on how to vote. You should instruct your broker to vote your shares. Your broker can tell you how to provide these instructions. If you do not give your broker instructions, your shares will be treated as broker non-votes with respect to all proposals. Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, will not count as votes cast at the Extraordinary General Meeting and will have no outcome on any of the Proposals.

What is a quorum?

A quorum is the minimum number of shares required to be present at the Extraordinary General Meeting for the Extraordinary General Meeting to be properly held under the Company’s Charter and the Companies Act (As Revised) of the Cayman Islands (the “Companies Act”). The presence, in person, by proxy, or if a corporation or other non-natural person, by its duly authorized representative or proxy, of the holders of a majority of the issued and outstanding Ordinary Shares entitled to vote at the Extraordinary General Meeting constitutes a quorum. Proxies that are marked “abstain” and proxies relating to “street name” shares that are returned to the Company but marked by brokers as “not voted” (so-called “broker non-votes”) will be treated as shares present for purposes of determining the presence of a quorum on all matters but will have no effect on the outcome of the Proposals. If a shareholder does not give the broker voting instructions, under applicable self-regulatory organization rules, its broker may not vote its shares on “non-discretionary” matters. The Company believes that each of the proposals is a “nondiscretionary” matter.

Who can vote at the Extraordinary General Meeting?

Holders of the Company’s Ordinary Shares as of the close of business on March 7, 2023, the record date, are entitled to vote at the Extraordinary General Meeting. As of the record date, there were 25,000,000 Ordinary Shares issued and outstanding, consisting of 20,000,000 Class A Ordinary Shares and 5,000,000 Class B Ordinary Shares. In deciding all matters at the Extraordinary General Meeting, each shareholder will be entitled to one vote for each share held by them on the record date. Holders of Class A Ordinary Shares and holders of

12

Class B Ordinary Shares will vote together as a single class on all matters submitted to a vote of the Company’s shareholders except as required by law. The Initial Shareholders own all of the Company’s issued and outstanding Class B Ordinary Shares, constituting approximately 20% of the Company’s issued and outstanding Ordinary Shares.

Registered Shareholders. If the Company’s shares are registered directly in your name with the Company’s transfer agent, Continental, you are considered the shareholder of record with respect to those shares. As the shareholder of record, you have the right to grant your voting proxy directly to the individuals listed on the proxy card or to vote in person at the Extraordinary General Meeting.

Street Name Shareholders. If the Company’s shares are held on your behalf in a brokerage account or by a bank or other nominee, you are considered the beneficial owner of those shares held in “street name,” and your broker or nominee is considered the shareholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker or nominee as to how to vote your shares. However, since a beneficial owner is not the shareholder of record, you may not vote your Ordinary Shares at the Extraordinary General Meeting unless you follow your broker’s procedures for obtaining a legal proxy. Throughout this proxy, the Company refers to shareholders who hold their shares through a broker, bank or other nominee as “street name shareholders.”

Does the Board recommend voting for the approval of the proposals?

Yes. After careful consideration of the terms and conditions of these proposals, the Board has determined that each of the proposals are in the best interests of the Company and its shareholders. The Board recommends that the Company’s shareholders vote “FOR” each of the proposals.

What interests do the Sponsor and the Company’s directors and officers have in the approval of the proposals?

The Sponsor and the Company’s directors and officers have interests in the proposals that may be different from, or in addition to, your interests as a shareholder. These interests include ownership of Class B Ordinary Shares and Private Placement Warrants that may become exercisable in the future and the possibility of future compensatory arrangements. See the section entitled “Proposal No. 1 — The Extension Proposal—Interests of the Sponsor and the Company’s Directors and Officers.”

Are there any dissenter’s or appraisal or similar rights for dissenting shareholders?

Neither the Companies Act nor the Company’s Charter provide for appraisal or other similar rights for dissenting shareholders in connection with any of the proposals to be voted upon at the Extraordinary General Meeting. Accordingly, the Company’s shareholders will have no right to dissent and obtain payment for their shares.

What happens to the Company’s warrants if the Extension is not approved?

If the Extension is not approved and the Company does not consummate an initial business combination by April 25, 2023, or by the applicable deadline as may be extended, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter subject to lawfully available funds therefor, redeem 100% of the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company (less taxes payable, and up to $100,000 of interest to pay dissolution expenses) divided by the total number of then-issued and outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as

13

promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the Board, liquidate and dissolve, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and other requirements of applicable law. There will be no redemption rights or liquidating distributions with respect to the Company’s warrants, which will expire worthless if the Company fails to complete the Company’s initial business combination by April 25, 2023 or by the applicable deadline as may be extended.

What happens to the Company’s warrants if the Extension is approved?

If the Extension is approved, the Company will continue to attempt to consummate an initial business combination until the Extended Date and up to the Additional Extension Date, as applicable, and will retain the blank check company restrictions previously applicable to it. The warrants will remain outstanding in accordance with their terms.

How are the funds in the Trust Account currently being held?

With respect to the regulation of special purpose acquisition companies like the Company (“SPACs”), on March 30, 2022, the SEC issued proposed rules (the “SPAC Rule Proposals”) relating to, among other items, disclosures in business combination transactions involving SPACs and private operating companies; the condensed financial statement requirements applicable to transactions involving shell companies; the use of projections by SPACs in SEC filings in connection with proposed business combination transactions; the potential liability of certain participants in proposed business combination transactions; and the extent to which SPACs could become subject to regulation under the Investment Company Act of 1940, as amended (the “Investment Company Act”), including a proposed rule that would provide SPACs a safe harbor from treatment as an investment company if they satisfy certain conditions that limit a SPAC’s duration, asset composition, business purpose and activities.

Following the IPO, the funds in the Trust Account were held in U.S. government treasury obligations with a maturity of 185 days or less or in money market funds investing solely in U.S. government treasury obligations and meeting certain conditions under Rule 2a-7 under the Investment Company Act.

How do I vote?

If you were a holder of record of Ordinary Shares on March 7, 2023, the record date for the Extraordinary General Meeting, you may vote in person or by virtual attendance at the Extraordinary General Meeting or by submitting a proxy for the Extraordinary General Meeting. You may submit your proxy by completing, signing, dating and returning the enclosed proxy card in the accompanying pre-addressed postage-paid envelope. If you hold your shares in “street name,” which means your shares are held of record by a broker, bank or nominee, you should contact your broker, bank or nominee to ensure that votes related to the shares you beneficially own are properly counted. In this regard, you must provide the broker, bank or nominee with instructions on how to vote your shares or, if you wish to attend the Extraordinary General Meeting and vote in person, obtain a valid proxy from your broker, bank or nominee.

How do I redeem my Ordinary Shares?

Pursuant to the Charter, a public shareholder may request that the Company redeem all or a portion of such public shareholder’s public shares for cash if the Extension Proposal is approved. You will be entitled to receive cash for any public shares to be redeemed only if you:

(1) (a) hold public shares or (b) hold public shares as part of units and elect to separate such units into the underlying public shares and public warrants prior to exercising your redemption rights with respect to the public shares; and

14

(2) prior to                     , Eastern Time, on                     , 2023 (two business days prior to the vote at the Extraordinary General Meeting), (a) submit a written request to Continental, the Company’s transfer agent, that the Company redeem your public shares for cash and (b) deliver your public shares to the transfer agent, physically or electronically through The Depository Trust Company.

Holders of units must elect to separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares. If holders hold their units in an account at a brokerage firm or bank, holders must notify their broker or bank that they elect to separate the units into the underlying public shares and public warrants, or if a holder holds units registered in its own name, the holder must contact the transfer agent directly and instruct it to do so. Public shareholders may elect to redeem all or a portion of their public shares even if they vote for the Extension Proposal.

Based upon the amount held in the Trust Account as of December 31, 2022, which was $206,946,000, and estimated interest income and taxes post-December 31, 2022, the Company estimates that the per-share price at which public shares may be redeemed from cash held in the Trust Account will be approximately $10.35 at the time of the Extraordinary General Meeting. The closing price of a Class A Ordinary Share on March 10, 2023, was $10.43. The Company cannot assure shareholders that they will be able to sell their Class A Ordinary Shares in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in its securities when such shareholders wish to sell their shares.

What should I do if I receive more than one set of voting materials?

You may receive more than one set of voting materials, including multiple copies of this proxy statement and multiple proxy cards or voting instruction cards, if your shares are registered in more than one name or are registered in different accounts. For example, if you hold your shares in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold shares. Please complete, sign, date and return each proxy card and voting instruction card that you receive in order to cast a vote with respect to all of your shares.

Who is paying for this proxy solicitation?

The Board is soliciting proxies for use at the Extraordinary General Meeting. All costs associated with this solicitation will be borne directly by the Company. The Company has engaged Morrow Sodali LLC (“Morrow”) to assist in the solicitation of proxies for the Extraordinary General Meeting. The Company has agreed to pay Morrow a fee of $25,000, plus associated disbursements for the Extraordinary General Meeting, and will reimburse Morrow for its reasonable out-of-pocket expenses and indemnify Morrow against certain losses, damages, expenses, liabilities or claims. The Company will also reimburse banks, brokers and other custodians, nominees and fiduciaries representing beneficial owners of Class A Ordinary Shares for their expenses in forwarding soliciting materials to beneficial owners of Class A Ordinary Shares and in obtaining voting instructions from those owners. The Company’s directors and officers may also solicit proxies by telephone, by facsimile, by mail, on the Internet or in person. They will not be paid any additional amounts for soliciting proxies.

THE EXTRAORDINARY GENERAL MEETING

Date, Time, Place and Purpose of the Extraordinary General Meeting

The Extraordinary General Meeting will be held in person or by proxy on                     , 2023, at                     , Eastern Time, at the offices of Latham & Watkins LLP, located at 1271 6th Ave, New York, New York 10020, or virtually via live webcast at https://www.cstproxy.com/gtac/2023, to consider and vote upon the proposals to be put to the Extraordinary General Meeting. While shareholders are encouraged to attend the meeting virtually, you will be permitted to attend the Extraordinary General Meeting in person at the offices of Latham & Watkins LLP.

At the Extraordinary General Meeting, you will be asked to consider and vote on proposals to:

(1) Proposal No. 1—The Extension Proposal—a proposal, by special resolution, to amend and restate the Company’s Charter pursuant to an amended and restated Charter in the form set forth in Annex A of the accompanying proxy statement to extend the date by which the Company must (a) consummate a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination (an “initial business combination”), (b) cease its operations except for the purpose of winding up if it fails to complete such initial business combination and (c) redeem all of the Class A Ordinary Shares, from April 25, 2023 to the Extended Date or to the Additional Extension Date at the election of the Company in two separate three-month extensions subject to satisfaction of certain conditions, including the deposit of up to $2,000,000 ($0.10 per unit in each case) for each three-month extension, into the Trust Account; and

(2) Proposal No. 2—The Adjournment Proposal—a proposal, by ordinary resolution, to approve the adjournment of the Extraordinary General Meeting to a later date or dates, if necessary or convenient, to permit further solicitation and vote of proxies in the event that there are insufficient votes for, or otherwise in connection with, the Extension Proposal, which will only be presented at the Extraordinary General Meeting if, based on the tabulated votes, there are not sufficient votes at the time of the Extraordinary General Meeting to approve the Extension Proposal, in which case the Adjournment Proposal will be the only proposal presented at the Extraordinary General Meeting.

Voting Power; Record Date

Only shareholders of record of the Company as of the close of business on March 7, 2023, are entitled to notice of, and to vote at, the Extraordinary General Meeting or any adjournment or postponement thereof. Each Ordinary Share entitles the holder thereof to one vote. If your shares are held in “street name” or are in a margin or similar account, you should contact your broker to ensure that votes related to the shares you beneficially own are properly counted. On the record date, there were 25,000,000 Ordinary Shares issued and outstanding, including 20,000,000 Class A Ordinary Shares and 5,000,000 Class B Ordinary Shares. The Company’s warrants do not have voting rights in connection with the proposals.

Quorum and Vote of Shareholders

A quorum is the minimum number of shares required to be present at the Extraordinary General Meeting for the Extraordinary General Meeting to be properly held under the Company’s Charter and the Companies Act. The presence, in person, by proxy, or if a corporation or other non-natural person, by its duly authorized representative or proxy, of the holders of a majority of the issued and outstanding Ordinary Shares entitled to vote at the Extraordinary General Meeting constitutes a quorum. Ordinary Shares that are present virtually during the Extraordinary General Meeting constitute Ordinary Shares represented “in person.” Proxies that are marked “abstain” and proxies relating to “street name” shares that are returned to the Company but marked by brokers as “not voted” (so-called “broker non-votes”) will be treated as shares present for purposes of determining the presence of a quorum on all matters but will have no effect on the outcome of the Proposals. If a shareholder does not give the broker voting instructions, under applicable self-regulatory organization rules, its broker may not vote its shares on “non-discretionary” matters. The Company believes each of the proposals constitutes a “non-discretionary” matter.

17

Votes Required

Approval of the Extension Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of holders of at least two-thirds of the Ordinary Shares who, being present in person (including virtually) or represented by proxy and entitled to vote thereon and who do so at the Extraordinary General Meeting. Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, will not count as votes cast at the Extraordinary General Meeting and will have no effect on the outcome of the Proposals.

Approval of the Adjournment Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of the Ordinary Shares who, being present in person (including virtually) or represented by proxy and entitled to vote thereon and who vote at the Extraordinary General Meeting. Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, will not count as votes cast at the Extraordinary General Meeting.

If you do not want any of the proposals to be approved, you must abstain, not vote or vote against such proposal. A shareholder’s failure to vote by proxy or to vote in person at the Extraordinary General Meeting will not be counted towards the number of Ordinary Shares required to validly establish a quorum. Broker non-votes and abstentions will be counted in connection with the determination of whether a valid quorum is established but will have no effect on the outcome of the Proposals.

Voting

The Board is asking for your proxy. Giving the Board your proxy means you authorize it to vote your shares at the Extraordinary General Meeting in the manner you direct. You may vote for or withhold your vote for the proposal or you may abstain from voting. All valid proxies received prior to the Extraordinary General Meeting will be voted. All shares represented by a proxy will be voted, and where a shareholder specifies by means of the proxy a choice with respect to any matter to be acted upon, the shares will be voted in accordance with the specification so made. If no choice is indicated on the proxy, the shares will be voted “FOR” each of the proposals and as the proxy holders may determine in their discretion with respect to any other matters that may properly come before the Extraordinary General Meeting.

You can vote your shares at the Extraordinary General Meeting in person or by proxy. You may attend the Extraordinary General Meeting via live webcast. You will be able to attend the Extraordinary General Meeting online, vote and submit your questions during the Extraordinary General Meeting by visiting https://www.cstproxy.com/gtac/2023. You may submit your proxy by completing, signing, dating and returning the enclosed proxy card in the accompanying pre-addressed postage-paid envelope. If you hold your shares in “street name,” which means your shares are held of record by a broker, bank or nominee, you should contact your broker, bank or nominee to ensure that votes related to the shares you beneficially own are properly counted. In this regard, you must provide the broker, bank or nominee with instructions on how to vote your shares or, if you wish to attend the Extraordinary General Meeting and vote in person, obtain a valid proxy from your broker, bank or nominee.

Proxies that are marked “abstain” and proxies relating to “street name” shares that are returned to the Company but marked by brokers as “not voted” (so-called “broker non-votes”) will be treated as shares present for purposes of determining the presence of a quorum on all matters. Abstentions and broker-non-votes will have no effect on the outcome of the Proposals. If a shareholder does not give the broker voting instructions, under applicable self-regulatory organization rules, its broker may not vote its shares on “non-discretionary” matters. The Company believes each of the proposals constitutes a “non-discretionary” matter.

Shareholders who have questions or need assistance in completing or submitting their proxy cards should contact the Company’s proxy solicitor, Morrow Sodali LLC, at (800) 662-5200 or by sending a letter to 333 Ludlow Street, 5th Floor, Stamford, Connecticut 06902, or by emailing GTAC.info@investor.morrowsodali.com.

Shareholders also may revoke their proxy by sending a notice of revocation to the Company’s Chief Executive Officer, which must be received prior to the vote at the Extraordinary General Meeting. However, if your shares are held in “street name” by your broker, bank or another nominee, you must contact your broker, bank or other nominee to change your vote.

In this regard, you must provide the broker, bank or nominee with instructions on how to vote your shares or, if you wish to attend the Extraordinary General Meeting and vote in person, obtain a valid proxy from your broker, bank or nominee.

Some banks and brokers have customers who beneficially own Ordinary Shares listed of record in the names of nominees. The Company intends to request banks and brokers to solicit such customers and will reimburse them for their reasonable out-of-pocket expenses for such solicitations. If any additional solicitation of the holders of the Company’s outstanding Ordinary Shares is deemed necessary, the Company (through its directors and officers) anticipates making such solicitation directly.

Dissenters’ Rights of Appraisal

Neither the Companies Act nor the Company’s Articles provide for appraisal or other similar rights for dissenting shareholders in connection with any of the proposals to be voted upon at the Extraordinary General Meeting. Accordingly, the Company’s shareholders will have no right to dissent and obtain payment for their shares.
