$220,000,000

22,000,000 Units

Art Technology Acquisition Corp. is a blank check company incorporated as a Cayman Islands exempted company for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, recapitalization, reorganization or similar business combination with one or more businesses, which we refer to throughout this prospectus as our initial business combination. We have not selected any specific business combination target and we have not, nor has anyone on our behalf, initiated any substantive discussions, directly or indirectly, with any business combination target.

This is an initial public offering of our securities. Each unit has an offering price of $10.00 and consists of one of our Class A ordinary shares and one-fourth of one redeemable warrant. Each whole warrant entitles the holder thereof to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment as provided herein, and only whole warrants are exercisable. No fractional warrants will be issued upon separation of the units and only whole warrants will trade. The warrants will become exercisable on the later of 30 days after the completion of our initial business combination and 12 months from the closing of this offering, and will expire five years after the completion of our initial business combination or earlier upon redemption or liquidation, as described in this prospectus. We have also granted the underwriters a 45-day option to purchase up to an additional 3,300,000 units to cover over-allotments, if any.

We will provide our public shareholders with the opportunity to redeem all or a portion of their Class A ordinary shares upon the completion of our initial business combination at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account described below (net of amounts withdrawn to fund our working capital requirements, subject to an annual limit of $400,000 of the interest earned on the funds held in the trust account, and to pay our taxes, other than excise taxes, if any (such amounts in the aggregate, “permitted withdrawals”)), divided by the number of then issued and outstanding Class A ordinary shares that were sold as part of the units in this offering, which we refer to collectively as our public shares, subject to the limitations described herein. See “Summary — The Offering — Redemption rights for public shareholders upon completion of our initial business combination” and “Summary — The Offering — Redemption of public shares and distribution and liquidation if no initial business combination” for more information.

Notwithstanding the foregoing redemption rights, if we seek shareholder approval of our initial business combination and we do not conduct redemptions in connection with our initial business combination pursuant to the tender offer rules, our amended and restated memorandum and articles of association provide that a public shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the shares sold in this offering without our prior consent. However, we would not restrict our shareholders’ ability to vote all of their shares (including all shares held by those shareholders that hold more than 15% of the shares sold in this offering) for or against our initial business combination. See “Summary — The Offering — Limitation on redemption rights of shareholders holding 15% or more of the shares sold in this offering if we hold shareholder vote” for further discussion on certain limitations on redemption rights.

Except for income taxes and permitted withdrawals, the proceeds placed in the trust account and the interest earned thereon shall not be used to pay for possible excise tax or any other fees or taxes that may be levied on the Company pursuant to any current, pending or future rules or laws, including without limitation any excise tax due under the Inflation Reduction Act of 2022 on any redemptions or share buybacks by the Company. If we have not completed our initial business combination within 24 months from the closing of this offering, or 27 months from the closing of this offering if we have executed a definitive agreement for our initial business combination within 24 months from the closing of this offering but have not completed our initial business combination within such 24-month period, we will 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 (net of permitted withdrawals and up to $100,000 of interest to pay dissolution expenses), divided by the number of then issued and outstanding public shares, subject to applicable law and as further described herein.

One of our sponsors, Art Technology Sponsor, LLC, a Delaware limited liability company, has committed to purchase 550,000 placement units at a price of $10.00 per unit ($5,500,000 in the aggregate) in a private placement that will close simultaneously with the closing of this offering, and Clear Street LLC (“Clear Street”) has committed to purchase an aggregate of 275,000 placement units at a price of $10.00 per unit ($2,750,000 in the aggregate) in a private placement that will close simultaneously with the closing of this offering. Each placement unit will be identical to the units sold in this offering, except as described in this prospectus. We refer to these units as the placement units throughout this prospectus. Certain institutional investors (none of which are affiliated with any member of our management or any other investor), which we refer to as the “non-managing sponsor investors” throughout this prospectus, have expressed an interest in acquiring, indirectly through the purchase of non-managing membership interests in the sponsor, up to all 550,000 placement units to be purchased by the sponsor. The sponsor also holds 8,708,333 Class B ordinary shares, which we refer to as “founder shares” as further described herein. Subject to each non-managing sponsor investor indirectly acquiring the placement units allocated to it in connection with the closing of this offering, the sponsor will issue additional membership interests at a nominal purchase price to the non-managing sponsor investors reflecting interests in an aggregate of approximately 2,750,000 founder shares held by our sponsor.

None of the non-managing sponsor investors have expressed to us an interest in purchasing any of the units in this offering and neither we nor the representative have had discussions with any non-managing sponsor investors regarding any purchases of units in this offering. If the non-managing sponsor investors purchase units in the offering, and depending on how many public units are purchased by the non-managing sponsor investors, the post-offering trading volume, volatility and liquidity of our securities may be reduced relative to what they would have been had the units been more widely offered and sold to other public investors. We do not expect any potential purchases of units by the non-managing sponsor investors to negatively impact our ability to meet Nasdaq listing eligibility requirements. In addition, the underwriters have full discretion to allocate the units to investors and may determine to sell fewer units to the non-managing sponsor investors, or none at all, and the purchase of the non-managing sponsor membership interests is not contingent upon their participation in this offering or vice-versa. The underwriters will receive the same upfront discounts and commissions and deferred underwriting commissions on units purchased by the non-managing sponsor investors, if any, as they will on the other units sold to the public in this offering. In addition, none of the non-managing sponsor investors will have any obligation to vote any of their public shares in favor of our initial business combination. Nevertheless, the non-managing sponsor investors will be incentivized to vote any of their public shares in favor of a business combination due to their indirect ownership through the sponsor of founder shares and placement units. Additionally, the non-managing sponsor investors have the potential to realize enhanced economic returns from their investments compared to other investors in this offering.

Our sponsor has purchased an aggregate of 8,708,333 Class B ordinary shares for an aggregate of $25,000,1,100,000 of which are subject to forfeiture by the holder thereof depending on the extent to which the underwriters’ over-allotment option is exercised. The Class B ordinary shares will automatically convert into Class A ordinary shares in connection with the consummation of our initial business combination, or at any time and from time to time at the option of the holder, on a one-for-one basis, subject to adjustment as provided herein. Because our sponsor acquired the Class B ordinary shares at a nominal price, our public shareholders will incur an immediate and substantial dilution upon the closing of this offering. If we increase or decrease the size of the offering, we will effect a share capitalization or a share repurchase or redemption or other appropriate mechanism, as applicable, with respect to our Class B ordinary shares immediately prior to the consummation of the offering in such amount as to maintain the ownership of founder shares by our sponsor, on an as-converted basis, at 25% of our issued and outstanding ordinary shares upon the consummation of this offering. Any conversion of Class B ordinary shares described herein will result in material dilution to our public shareholders due to the anti-dilution rights, which will take effect as a compulsory redemption of Class B ordinary shares and an issuance of Class A ordinary shares as a matter of Cayman Islands law. Such dilution could materially increase to the extent that the anti-dilution provision of the founder shares results in the issuance of Class A ordinary shares on a greater than one-to-one basis upon conversion of the founder shares at the time of our initial business combination to maintain the number of founder shares at 25%. In the case that additional Class A ordinary shares, or equity-linked securities (as described herein), are issued or deemed issued in excess of the amounts issued in this offering and related to the closing of our initial business combination, the ratio at which the Class B ordinary shares will convert into Class A ordinary shares will be adjusted (unless the holders of a majority of the issued and outstanding Class B ordinary shares agree to waive such anti-dilution adjustment with respect to any such issuance or deemed issuance) so that the number of

Class A ordinary shares issuable upon conversion of all Class B ordinary shares will equal, in the aggregate, 25% of the aggregate of our issued and outstanding founder shares, placement shares and public shares after this offering and the private placement, plus all Class A ordinary shares and equity-linked securities issued or deemed issued in connection with our initial business combination, excluding any shares or equity-linked securities issued, or to be issued, to any seller in the business combination. Prior to our initial business combination, holders of the Class B ordinary shares will have the right to appoint all of our directors and may remove members of the board of directors for any reason. In the event that there are no longer any Class B ordinary shares outstanding prior to our initial business combination, holders of Class A ordinary shares will have the right to vote on the appointment or removal of any member of the board of directors. On any other matter submitted to a vote of our shareholders, holders of the Class B ordinary shares and holders of the Class A ordinary shares will vote together as a single class, except as required by law. See “Summary — The Offering — Sponsor Information,” “Summary — The Offering — Founder Shares,” “Summary — The Offering — Founder Shares Conversion and Anti-Dilution Rights” and “Description of Securities — Founder Shares” for further discussion on our sponsor’s and our affiliates’ securities and compensation.

As more fully discussed in “Management — Conflicts of Interest,” certain of our officers and directors presently has, and any of them in the future may have, additional fiduciary, contractual or other obligations or duties to one or more other entities pursuant to which such officer or director is or will be required to present a business combination opportunity to such entities prior to or rather than to us. The low price that our sponsor, executive officers and directors (directly or indirectly) paid for the founder shares creates an incentive whereby our officers and directors could potentially make a substantial profit even if we select an acquisition target that subsequently declines in value and is unprofitable for public shareholders. If we are unable to complete our initial business combination within the completion window, or by such earlier liquidation date as our board of directors may approve, the founder shares and placement units may expire worthless, except to the extent they receive liquidating distributions from assets outside the trust account, which could create an incentive for our sponsor, executive officers and directors to complete a transaction even if we select an acquisition target that subsequently declines in value and is unprofitable for public shareholders. Further, each of our officers and directors may have a conflict of interest with respect to evaluating a particular business combination if the retention or resignation of any such officers or directors was included by a target business as a condition to any agreement with respect to our initial business combination. Additionally, we will pay our sponsor or its affiliate or designee a total of $30,000 per month for office space, utilities and shared personnel support services, as described elsewhere in this prospectus. We may also pay our Chief Financial Officer, R. Maxwell Smeal, up to $12,500 per month, and our Chief Operating Officer, Emmanuelle Cohen, up to $8,333 per month. Upon consummation of this offering, we will repay up to $300,000 in loans made to us by our sponsor to cover offering-related and organizational expenses. In order to finance transaction costs in connection with an intended initial business combination, our sponsor or one of its affiliates may, but is not obligated to, loan us additional funds to fund our additional working capital requirements and transaction costs. If we complete our initial business combination, we would repay such loaned amounts out of the proceeds of the trust account released to us. Otherwise, such loans would be repaid only out of funds held outside the trust account. Up to $2,500,000 of such loans may be convertible into units at the time of the business combination at a price of $10.00 per unit at the option of the lender. See the sections titled “Summary — The Offering — Sponsor Information,” “Summary — The Offering — Conflicts of Interest”, “Risk Factors — Risks Relating to our Search for, Consummation of, or Inability to Consummate, a Business Combination and Post-Business Combination Risks — Since our sponsor, officers and directors and any other holder of our founder shares, including any non-managing sponsor investors, will lose their entire investment in us if our initial business combination is not completed (other than with respect to any public shares they may acquire during or after this offering), and because our sponsor, officers and directors and any other holder of our founder shares, including any non-managing sponsor investors, directly or indirectly may profit substantially from a business combination as a result of their ownership of founder shares even under circumstances where our public shareholders would experience losses in connection with their investment, a conflict of interest may arise in determining whether a particular business combination target is appropriate for our initial business combination, including in connection with the shareholder vote in respect thereto.” and “Management — Conflicts of Interest” for more information.

Prior to this offering, there has been no public market for our units, Class A ordinary shares or warrants. We have applied to list our units on the Global Market tier of The Nasdaq Stock Market, or Nasdaq, under the symbol “ARTCU” on or promptly after the date of this prospectus. We cannot guarantee that our securities will be approved for listing on Nasdaq; however, Nasdaq listing approval of our securities is a condition to the closing of this offering.

The Class A ordinary shares and warrants comprising the units will begin separate trading on the 52 nd day following the date of this prospectus unless Clear Street informs us of its decision to allow earlier separate trading, subject to our filing a Current Report on Form 8-K with the Securities and Exchange Commission, or the SEC, containing an audited balance sheet reflecting our receipt of the gross proceeds of this offering, and issuing a press release announcing when such separate trading will begin. Once the securities comprising the units begin separate trading, we expect that the Class A ordinary shares and warrants will be listed on Nasdaq under the symbols “ARTC” and “ARTCW,” respectively.

We are responsible for the information contained in this prospectus. We have not authorized anyone to provide any information or to make any representations other than those contained in this prospectus. We and the underwriters take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. This prospectus is an offer to sell only the units offered hereby, but only under circumstances and in jurisdictions where it is lawful to do so. The information contained in this prospectus is current only as of its date.

We are an “emerging growth company” under applicable federal securities laws and will be subject to reduced public company reporting requirements. Investing in our securities involves risks. See “Risk Factors” on page 48. Investors will not be entitled to protections normally afforded to investors in Rule 419 blank check offerings.

(1) $0.20 per unit, or $4,400,000 in the aggregate, is payable upon the closing of this offering, independent of whether the underwriters’ over-allotment option is exercised or not. In addition, (i) $0.40 per unit sold in the base offering, or $8,800,000 in the aggregate, and (ii) $0.60 per unit sold pursuant to the underwriters’ over-allotment option, if any, or up to an additional $1,980,000 in the aggregate, is payable to the underwriters for deferred underwriting commissions to be placed in a trust account located in the United States as described herein. The deferred commissions will be released to Clear Street for its own account concurrently with completion of an initial business combination, but such deferred commissions shall be due and payable, with respect to up to 75% of such deferred commissions, in our sole discretion. Does not include certain fees and expenses payable to the underwriters in connection with this offering. See also “Underwriting” for a description of underwriting compensation payable to the underwriters.

Of the proceeds we receive from this offering and the sale of the placement units described in this prospectus, $220.0 million or $253.0 million if the underwriters’ over-allotment option is exercised in full ($10.00 per unit in either case) will be deposited into a U.S.-based trust account maintained with Continental Stock Transfer & Trust Company acting as trustee. Except with respect to interest earned on the funds held in the trust account that may be released to us for permitted withdrawals, the funds held in the trust account will not be released from the trust account until the earliest to occur of (a) the completion of our initial business combination, (b) the redemption of any public shares properly submitted in connection with a shareholder vote to amend our amended and restated memorandum and articles of association (i) to modify the substance or timing of our obligation to redeem 100% of our public shares if we do not complete our initial business combination within the completion window, or (ii) with respect to any other provisions relating to shareholders’ rights or pre-initial business combination activity and (c) the redemption of our public shares if we are unable to complete our business combination within the completion window, subject to applicable law. The proceeds deposited in the trust account could become subject to the claims of our creditors, if any, which could have priority over the claims of our public shareholders.

Because our sponsor acquired the founder shares at a nominal price, our public shareholders will incur an immediate and substantial dilution upon the closing of this offering, assuming no value is ascribed to the warrants included in the units. Additionally, the Class A ordinary shares issuable in connection with the conversion of the founder shares may result in material dilution to our public shareholders due to the anti-dilution rights of our founder shares that may result in an issuance of Class A ordinary shares on a greater than one-for-one basis upon conversion. Further, the Class A ordinary shares issuable in connection with the exercise of the placement warrants underlying placement units, including those placement units converted from working capital loans (as described in this prospectus), may result in material dilution to our public shareholders if the $11.50 exercise price of the placement

warrants is significantly less than the market price of our shares at the time such placement warrants are exercised or if the placement warrants are exercised on a cashless basis. See the section titled “Risk Factors — Risks Relating to our Management Team — The nominal purchase price paid by our sponsor for the founder shares may result in significant dilution to the implied value of your public shares upon the consummation of our initial business combination, and our sponsor is likely to make a substantial profit on its investment in us in the event we consummate an initial business combination, even if the business combination causes the trading price of our ordinary shares to materially decline.”

The following table illustrates the difference between the public offering price per unit and our net tangible book value per share (NTBV), as adjusted to give effect to this offering and assuming the redemption of our public shares at varying levels and the exercise in full and no exercise of the over-allotment option. See the section entitled “Dilution” for more information.

Our sponsor and members of our management team will directly or indirectly own our securities following this offering, and accordingly, they may have a conflict of interest in determining whether a particular target business is an appropriate business with which to effectuate our initial business combination. Additionally, each of our officers and directors presently has, and any of them in the future may have additional, fiduciary, contractual or other obligations or duties to one or more other entities pursuant to which such officer or director is or will be required to present a business combination opportunity to such entities prior to or rather than to us. As a result, there may be actual or potential material conflicts of interest between our sponsor and its affiliates on one hand, and purchasers in this offering on the other. See the sections titled “Proposed Business — Sourcing of Potential Business Combination Targets” and “Management — Conflicts of Interest” for more information.

The underwriters are offering the units for sale on a firm commitment basis. Delivery of the units will be made on or about , 2025.

Neither the SEC nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

No offer or invitation to subscribe for securities may be made to the public in the Cayman Islands.
