FutureCorp Space Acquisition 1

Note 1 — Organization and Business Operations

FutureCorp Space Acquisition 1 (the “Company”) is a blank check company incorporated as a Cayman Islands exempted corporation on March 12, 2026. The Company was incorporated for the purpose of effecting a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company has not selected any specific Business Combination target, and the Company has not, nor has anyone on its behalf, engaged in any substantive discussions, directly or indirectly, with any Business Combination target with respect to an initial Business Combination with the Company.

As of March 31, 2026, the Company has not commenced any operations. All activity for the period from March 12, 2026 (inception) through March 31, 2026 relates to the Company’s formation and the Proposed Public Offering (as defined below). The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income on the proceeds derived from the Proposed Public Offering (as defined below). The Company has selected December 31 as its fiscal year end.

The Company’s Sponsor is FutureCorp Space Acquisition 1 LLC (the “Sponsor”). The Company’s ability to commence operations is contingent upon obtaining adequate financial resources through a Proposed Public Offering of 20,000,000 units at $10.00 per unit (the “Units”) (or 23,000,000 Units if the underwriters’ over-allotment option is exercised in full), which is discussed in Note 3 (the “Proposed Public Offering”), and the sale of an aggregate of 6,000,000 Private Placement Warrants (whether or not the underwriters’ over-allotment option is exercised in full) (the “Private Placement Warrants”) to the Sponsor and Cantor Fitzgerald & Co., the representative of the underwriters of the Proposed Public Offering, at a price of $1.00 per warrant, or $6,000,000 in the aggregate, in a private placement that will close simultaneously with the Proposed Public Offering. Of those 6,000,000 Private Placement Warrants, the Sponsor has agreed to purchase 4,000,000 Private Placement Warrants (whether or not the underwriters’ over-allotment option is exercised in full) and Cantor Fitzgerald & Co. has agreed to purchase 2,000,000 Private Placement Warrants (whether or not the underwriters’ over-allotment option is exercised in full). Each whole warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share. The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Proposed Public Offering and the Private Placement Warrants, although substantially all of the net proceeds are intended to be generally applied toward consummating a Business Combination (less deferred underwriting commissions).

The Company’s Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the net balance in the Trust Account (as defined below) (excluding the amount of deferred underwriting discounts held and taxes payable on the income earned on the Trust Account) at the time of the signing an agreement to enter into a Business Combination. However, the Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). There is no assurance that the Company will be able to successfully effect a Business Combination.

Upon the closing of the Proposed Public Offering, management has agreed that an aggregate of $10.00 per Unit sold in the Proposed Public Offering will be held in a Trust Account (the “Trust Account”) and initially be invested only in U.S. government treasury obligations with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act which invest only in direct U.S. government treasury obligations; the holding of these assets in this form is intended to be temporary and for the sole purpose of facilitating the intended Business Combination. To mitigate the risk that the Company might be deemed to be an investment company for purposes of the Investment Company Act, which risk increases the longer that the Company holds investments in the Trust Account, the Company may, at any time (based on the management team’s ongoing assessment of all factors related to the Company’s potential status under the Investment Company Act), instruct the trustee to liquidate the investments held in the Trust Account and instead to hold the funds in the Trust Account in cash or in an interest bearing demand deposit account at a bank. Except with respect to interest earned on the funds

Note 1 — Organization and Business Operations (cont.)

held in the Trust Account that may be released to the Company to pay its taxes, if any (other than excise or similar taxes), and up to $100,000 of interest income to pay dissolution expenses, the proceeds from the Proposed Public Offering and the sale of the Private Placement Warrants will not be released from the Trust Account until the earliest of (i) the completion of the Company’s initial Business Combination, (ii) the redemption of the Company’s public shares if the Company is unable to complete the initial Business Combination within 24 months from the closing of the Proposed Public Offering or by such earlier liquidation date as the Company’s board of directors may approve (the “Completion Window”), subject to applicable law, or (iii) the redemption of the Company’s public shares properly submitted in connection with a shareholder vote to amend the Company’s amended and restated memorandum and articles of association to (A) modify the substance or timing of the Company’s obligation to allow redemption in connection with the initial Business Combination or to redeem 100% of the Company’s public shares if the Company has not consummated an initial Business Combination within the Completion Window or (B) with respect to any other material provisions relating to the rights of holders of Class A ordinary shares or pre-initial Business Combination activity. The proceeds deposited in the Trust Account could become subject to the claims of the Company’s creditors, if any, which could have priority over the claims of the Company’s public shareholders.

The Company will provide the Company’s public shareholders with the opportunity to redeem all or a portion of their public shares upon the completion of the initial Business Combination either (i) in connection with a general meeting called to approve the initial Business Combination or (ii) without a shareholder vote by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a proposed initial Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The public shareholders will be entitled to redeem their shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account calculated as of two business days prior to the consummation of the initial Business Combination, including interest earned on the funds held in the Trust Account (less taxes payable (other than excise or similar taxes)), divided by the number of then outstanding public shares, subject to the limitations. The Company will not use the proceeds placed in the Trust Account, or the interest earned on the proceeds placed in the Trust Account, to pay for possible excise or similar taxes that may be levied on the Company pursuant to any current, pending or future rules or laws, including any excise tax due under the Inflation Reduction Act of 2022 on any redemptions or stock buybacks by the Company, prior to the release of such funds from the Trust Account upon the initial Business Combination. The amount in the Trust Account is initially anticipated to be $10.00 per public share.

The ordinary shares subject to redemption will be recorded at a redemption value and classified as temporary equity upon the completion of the Proposed Public Offering, in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 480, “Distinguishing Liabilities from Equity.”

The Company will have only the duration of the Completion Window to complete the initial Business Combination. However, if the Company is unable to complete its initial Business Combination within the Completion Window, the Company will as promptly as reasonably possible but not more than ten business days thereafter, redeem 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 (which interest shall be net of taxes payable (other than excise or similar taxes) and up to $100,000 to pay dissolution expenses), divided by the number of then issued and outstanding public shares, which redemption will constitute full and complete payment for the public shares and completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation or other distributions, if any), subject to the Company’s obligations under Cayman Islands law to provide for claims of creditors and subject to the other requirements of applicable law.

The Sponsor, officers and directors have entered into a letter agreement with the Company, pursuant to which they have agreed to (i) waive their redemption rights with respect to their founder shares and public shares in connection with the completion of the initial Business Combination; (ii) waive their redemption rights with respect to their founder shares and public shares in connection with a shareholder vote to approve an amendment to the Company’s amended and restated memorandum and articles of association; (iii) waive their rights to liquidating distributions from the Trust Account with respect to their founder shares if the Company fails to complete the initial Business Combination

Note 1 — Organization and Business Operations (cont.)

within the Completion Window, although they will be entitled to liquidating distributions from the Trust Account with respect to any public shares they hold if the Company fails to complete the initial Business Combination within the Completion Window and to liquidating distributions from assets outside the Trust Account; and (iv) vote any founder shares held by them and any public shares purchased during or after the Proposed Public Offering (including in open market and privately negotiated transactions, aside from shares they may purchase in compliance with the requirements of Rule 14e-5 under the Exchange Act, which would not be voted in favor of approving the Business Combination) in favor of the initial Business Combination.

The Company’s Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or other similar agreement or Business Combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per public share and (ii) the actual amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per share due to reductions in the value of the trust assets, less taxes payable (other than excise or similar taxes), provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company’s indemnity of the underwriters of the Proposed Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). However, the Company has not asked the Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and the Company believes that the Sponsor’s only assets are securities of the Company. Therefore, the Company cannot assure that the Sponsor would be able to satisfy those obligations.

Going Concern Consideration

As of March 31, 2026, the Company had no cash and a working capital deficit of $55,810 (excluding deferred offering costs). The Company expects to continue to incur significant costs in pursuit of its acquisition plans. In connection with the Company’s assessment of going concern considerations in accordance with FASB ASC Topic 205-40, “Financial Presentation — Going Concern,” the Company lacks the financial resources it needs to sustain operations for a reasonable period of time, which is considered to be one year from the date of the issuance of the financial statements. This condition raises substantial doubt about the Company’s ability to continue as a going concern. Management plans to address this uncertainty through the Proposed Public Offering as discussed in Note 3. There is no assurance that the Company’s plans to raise capital will be successful. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Note 2 — Significant Accounting Policies

Basis of Presentation

The accompanying financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”).

Emerging Growth Company Status

The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404

Note 2 — Significant Accounting Policies (cont.)

of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates.

Deferred Offering Costs

The Company complies with the requirements of the FASB ASC Topic 340-10-S99 and SEC Staff Accounting Bulletin Topic 5A, “Expenses of Offering.” Deferred offering costs consist principally of professional and registration fees that are related to the Proposed Public Offering. FASB ASC Topic 470-20, “Debt with Conversion and Other Options,” addresses the allocation of proceeds from the issuance of convertible debt into its equity and debt components. The Company applies this guidance to allocate Proposed Public Offering proceeds from the Units between Class A ordinary shares and warrants, using the residual method by allocating Proposed Public Offering proceeds first to assigned value of the warrants and then to the Class A ordinary shares. Offering costs allocated to the Class A ordinary shares subject to possible redemption will be charged to temporary equity and offering costs allocated to the Public and Private Placement Warrants will be charged to shareholder’s equity as Public Warrants (defined below) and Private Placement Warrants after management’s evaluation will be accounted for under equity treatment. Should the Proposed Public Offering prove to be unsuccessful, these deferred costs, as well as additional expenses to be incurred, will be charged to operations.

Fair Value of Financial Instruments

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB ASC Topic 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the balance sheet, primarily due to its short-term nature.

Net Loss per Ordinary Share

Net loss per ordinary share is computed by dividing net loss by the weighted average number of ordinary shares outstanding during the period, excluding ordinary shares subject to forfeiture. Weighted average shares were reduced for the effect of an aggregate of 750,000 ordinary shares that are subject to forfeiture if the over-allotment option is

Note 2 — Significant Accounting Policies (cont.)

not exercised by the underwriters (see Note 7). At March 31, 2026, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into ordinary shares and then share in the earnings of the Company. As a result, diluted loss per ordinary share is the same as basic loss per ordinary share for the period presented.

Income Taxes

The Company accounts for income taxes under FASB ASC Topic 740, “Income Taxes,” which requires an asset and liability approach to financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed for differences between the financial statement and tax bases of assets and liabilities that will result in future taxable or deductible amounts, based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

FASB ASC Topic 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company’s management determined that the Cayman Islands is the Company’s major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. As of March 31, 2026, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position.

The Company is considered to be an exempted Cayman Islands company with no connection to any other taxable jurisdiction and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company’s tax provision was zero for the period presented.

Derivative Financial Instruments

The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with FASB ASC Topic 815, “Derivatives and Hedging”. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then re-valued at each reporting date, with changes in the fair value reported in the statement of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative liabilities are classified in the balance sheet as current or non-current based on whether or not net cash settlement or conversion of the instrument could be required within 12 months of the balance sheet date. The underwriters’ over-allotment option is deemed to be a freestanding financial instrument indexed on the contingently redeemable shares and will be accounted for as a liability pursuant to FASB ASC Topic 480 if not fully exercised at the time of the Proposed Public Offering.

Warrant Instruments

The Company will account for the Public Warrants (defined below) and Private Placement Warrants to be issued in connection with the Proposed Public Offering and the private placement in accordance with the guidance contained in FASB ASC Topic 815, “Derivatives and Hedging”. Accordingly, the Company evaluated and will classify the warrant instruments under equity treatment at their assigned values. There are no Public or Private Placement Warrants currently outstanding as of March 31, 2026.

Recent Accounting Pronouncements

Management does not believe that any recently issued, but not effective, accounting standards, if currently adopted, would have a material effect on the Company’s financial statements.

Note 3 — Proposed Public Offering

In the Proposed Public Offering, the Company will offer for sale up to 20,000,000 Units (or 23,000,000 Units if the underwriters’ over-allotment option is exercised in full) at a purchase price of $10.00 per Unit. Each Unit that the Company is offering has a price of $10.00 and consists of one Class A ordinary share, and one-half of one redeemable warrant (“Public Warrants”). Each whole warrant will entitle the holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment. Each warrant will become exercisable 30 days after the completion of the initial Business Combination and will expire five years after the completion of the initial Business Combination, or earlier upon redemption or liquidation.

Public Warrants —No Public Warrants are currently outstanding. Each whole warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment as discussed herein. The warrants cannot be exercised until 30 days after the completion of the initial Business Combination, and will expire at 5:00 p.m., New York City time, five years after the completion of the initial Business Combination or earlier upon redemption or liquidation.

The Company will not be obligated to deliver any Class A ordinary shares pursuant to the exercise of a warrant and will have no obligation to settle such warrant exercise unless a registration statement under the Securities Act with respect to the Class A ordinary shares underlying the warrants is then effective and a prospectus relating thereto is current. No warrant will be exercisable and the Company will not be obligated to issue a Class A ordinary share upon exercise of a warrant unless the Class A ordinary share issuable upon such warrant exercise has been registered on a registration statement on Form S-1, Form S-3, Form F-1, or Form F-3, as applicable, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants. In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a warrant, the holder of such warrant will not be entitled to exercise such warrant and such warrant may have no value and expire worthless. In no event will the Company be required to net cash settle any warrant. In the event that a registration statement is not effective for the exercised warrants, the purchaser of a unit containing such warrant will have paid the full purchase price for the unit solely for the Class A ordinary share underlying such unit.

Under the terms of the warrant agreement, the Company has agreed that, as soon as practicable, but in no event later than 20 business days after the closing of its Business Combination, it will use commercially reasonable efforts to file with the SEC a post-effective amendment to the registration statement for the Proposed Public Offering or a new registration statement on a registration statement on Form S-1, Form S-3, Form F-1, or Form F-3, as applicable, covering the registration under the Securities Act of the Class A ordinary shares issuable upon exercise of the warrants and thereafter will use its commercially reasonable efforts to cause the same to become effective within 60 business days following the Company’s initial business combination and to maintain a current prospectus relating to the Class A ordinary shares issuable upon exercise of the warrants until the expiration of the warrants in accordance with the provisions of the warrant agreement. If a registration statement covering the Class A ordinary shares issuable upon exercise of the warrants is not effective by the sixtieth (60 th) business day after the closing of the initial Business Combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company will have failed to maintain an effective registration statement, exercise warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption. Notwithstanding the above, if the Class A ordinary shares are at the time of any exercise of a warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of public warrants who exercise their warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elects, the Company will not be required to file or maintain in effect a registration statement, and in the event the Company does not so elect, the Company will use its commercially reasonable efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available.

If the holders exercise their public warrants on a cashless basis, they would pay the warrant exercise price by surrendering the warrants for that number of Class A ordinary shares equal to the quotient obtained by dividing (x) the product of the number of Class A ordinary shares underlying the warrants, multiplied by the excess of the “fair market

Note 3 — Proposed Public Offering (cont.)

value” of the Class A ordinary shares over the exercise price of the warrants by (y) the fair market value. The “fair market value” is the average reported closing price of the Class A ordinary shares for the 10 trading days ending on the third trading day prior to the date on which the notice of exercise is received by the warrant agent or on which the notice of redemption is sent to the holders of warrants, as applicable.

Redemption of Warrants When the Price per Class A Ordinary Share Equals or Exceeds $18.00: The Company may redeem the outstanding warrants:

• in whole and not in part;

• at a price of $0.01 per warrant;

• upon a minimum of 30 days’ prior written notice of redemption (the “30-day redemption period”); and

• if, and only if, the closing price of the Class A ordinary shares equals or exceeds $18.00 per share (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a warrant) for any 20 trading days within a 30-trading day period commencing at least 30 days after completion of the Company’s initial Business Combination and ending three business days before the Company sends the notice of redemption to the warrant holders.

Additionally, if the number of outstanding Class A ordinary shares is increased by a share capitalization payable in Class A ordinary shares, or by a subdivision of ordinary shares or other similar event, then, on the effective date of such share capitalization, subdivision or similar event, the number of Class A ordinary shares issuable on exercise of each warrant will be increased in proportion to such increase in the outstanding ordinary shares. A rights offering made to all or substantially all holders of ordinary shares entitling holders to purchase Class A ordinary shares at a price less than the fair market value will be deemed a share capitalization of a number of Class A ordinary shares equal to the product of (i) the number of Class A ordinary shares actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for Class A ordinary shares) and (ii) the quotient of (x) the price per Class A ordinary share paid in such rights offering and (y) the fair market value. For these purposes (i) if the rights offering is for securities convertible into or exercisable for Class A ordinary shares, in determining the price payable for Class A ordinary shares, there will be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) fair market value means the volume weighted average price of Class A ordinary shares as reported during the ten (10) trading day period ending on the trading day prior to the first date on which the Class A ordinary shares trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

Note 4 — Private Placement

The Sponsor and Cantor Fitzgerald & Co. have committed to purchase an aggregate of 6,000,000 Private Placement Warrants (whether or not the underwriters’ over-allotment option is exercised in full), each exercisable to purchase one Class A ordinary share at $11.50 per share, at a price of $1.00 per warrant, or $6,000,000 in the aggregate, in a private placement that will close simultaneously with the Proposed Public Offering. Of those 6,000,000 Private Placement Warrants, the Sponsor has agreed to purchase 4,000,000 Private Placement Warrants (whether or not the underwriters’ over-allotment option is exercised in full) and Cantor Fitzgerald & Co. has agreed to purchase 2,000,000 Private Placement Warrants (whether or not the underwriters’ over-allotment option is exercised in full). Each whole warrant entitles the registered holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment.

The Private Placement Warrants will be identical to the Public Warrants sold in the Proposed Public Offering except that, so long as they are held by the Sponsor, Cantor Fitzgerald & Co., or their permitted transferees, the Private Placement Warrants (i) may not (including the Class A ordinary shares issuable upon exercise of these Private Placement Warrants), subject to certain limited exceptions, be transferred, assigned or sold by the holders until 30 days after the completion of the initial Business Combination, (ii) will be entitled to registration rights and (iii) with respect

Note 4 — Private Placement (cont.)

to private placement warrants held by Cantor Fitzgerald & Co., will not be exercisable more than five years from the commencement of sales in this offering in accordance with Financial Industry Regulatory Authority (“FINRA”) Rule 5110(g)(8).

The Sponsor, and the officers and directors of the Company, have entered into a letter agreement with the Company, pursuant to which they have agreed to (i) waive their redemption rights with respect to their founder shares and public shares in connection with the completion of the initial Business Combination; (ii) waive their redemption rights with respect to their founder shares and public shares in connection with a shareholder vote to approve an amendment to the Company’s amended and restated memorandum and articles of association (A) to modify the substance or timing of the Company’s obligation to allow redemption in connection with the initial Business Combination or to redeem 100% of the public shares if the Company has not consummated an initial Business Combination within the Completion Window or (B) with respect to any other material provisions relating to the rights of holders of Class A ordinary shares or pre-initial Business Combination activity; (iii) waive their rights to liquidating distributions from the Trust Account with respect to their founder shares if the Company fails to complete the initial Business Combination within the Completion Window, although they will be entitled to liquidating distributions from the Trust Account with respect to any public shares they hold if the Company fails to complete the initial Business Combination within the Completion Window and to liquidating distributions from assets outside the Trust Account; and (iv) vote any founder shares held by them and any public shares purchased during or after the Proposed Public Offering (including in open market and privately negotiated transactions, aside from shares they may purchase in compliance with the requirements of Rule 14e-5 under the Exchange Act, which would not be voted in favor of approving the Business Combination) in favor of the initial Business Combination.

Note 5 — Related Party Transactions

Founder Shares

On March 31, 2026, the Sponsor made a capital contribution of $25,000, or approximately $0.004 per share, to cover certain of the Company’s expenses, for which the Company issued 5,750,000 founders shares to the Sponsor. Up to 750,000 of the founder shares may be surrendered by the Sponsor for no consideration depending on the extent to which the underwriters’ over-allotment option is exercised.

The Company’s initial shareholders have agreed not to transfer, assign or sell any of their founder shares and any Class A ordinary shares issued upon conversion thereof until the earlier to occur of (i) one year after the completion of the initial Business Combination or (ii) the date on which the Company completes a liquidation, merger, share exchange or other similar transaction after the initial Business Combination that results in all of the Company’s shareholders having the right to exchange their Class A ordinary shares for cash, securities or other property. Any permitted transferees will be subject to the same restrictions and other agreements of the Company’s initial shareholders with respect to any founder shares (the “Lock-up”). Notwithstanding the foregoing, if (1) the closing price of the Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share subdivisions, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the initial Business Combination or (2) if the Company consummates a transaction after the initial Business Combination which results in the Company’s shareholders having the right to exchange their shares for cash, securities or other property, the founder shares will be released from the Lock-up.

Promissory Note — Related Party

On March 31, 2026, the Sponsor agreed to loan the Company an aggregate of up to $400,000 to be used for a portion of the expenses of the Proposed Public Offering. The loan is non-interest bearing, unsecured and due at the earlier of December 31, 2026 or the closing of the Proposed Public Offering. The loan will be repaid out of the $750,000 of offering proceeds that has been allocated to the payment of offering expenses. As of March 31, 2026, the Company had no borrowings under the promissory note.

Note 5 — Related Party Transactions (cont.)

Administrative Services Agreement

The Company will enter into an agreement with the Sponsor to pay an aggregate of $20,000 per month for office space, utilities, secretarial and administrative support, and other related services rendered to members of the Company’s management team prior to the consummation of the initial Business Combination, which amounts will be accrued from the closing of the Proposed Public Offering and will only be payable upon the successful completion of the initial Business Combination. As of March 31, 2026, such arrangements had not been executed.

Related Party Loans

In order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required (the “Working Capital Loans”). If the Company completes a Business Combination, the Company would repay the Working Capital Loans. In the event that a Business Combination does not close, the Company may use a portion of the working capital held outside the Trust Account to repay the Working Capital Loans but no proceeds from the Trust Account would be used to repay the Working Capital Loans. Up to $1,500,000 of such Working Capital Loans may be convertible into private placement warrants of the post-Business Combination entity at a price of $1.00 per warrant at the option of the lender. The warrants would be identical to the Private Placement Warrants. As of March 31, 2026, no such Working Capital Loans were outstanding.

Note 6 — Commitments and Contingencies

Risks and Uncertainties

The United States and global markets are experiencing volatility and disruption following the geopolitical instability resulting from the ongoing Russia-Ukraine conflict and the Israel-Hamas conflict. In response to the ongoing Russia-Ukraine conflict, the North Atlantic Treaty Organization (“NATO”) deployed additional military forces to eastern Europe, and the United States, the United Kingdom, the European Union and other countries have announced various sanctions and restrictive actions against Russia, Belarus and related individuals and entities, including the removal of certain financial institutions from the Society for Worldwide Interbank Financial Telecommunication payment system. Certain countries, including the United States, have also provided and may continue to provide military aid or other assistance to Ukraine and to Israel, increasing geopolitical tensions among a number of nations. The invasion of Ukraine by Russia and the Israel-Hamas conflict and the resulting measures that have been taken, and could be taken in the future, by NATO, the United States, the United Kingdom, the European Union, Israel and its neighboring states and other countries have created global security concerns that could have a lasting impact on regional and global economies. Although the length and impact of the ongoing conflicts are highly unpredictable, they could lead to market disruptions, including significant volatility in commodity prices, credit and capital markets, as well as supply chain interruptions and increased cyberattacks against U.S. companies. Additionally, any resulting sanctions could adversely affect the global economy and financial markets and lead to instability and lack of liquidity in capital markets.

Any of the above mentioned factors, or any other negative impact on the global economy, capital markets or other geopolitical conditions resulting from the Russian invasion of Ukraine, the Israel-Hamas conflict and subsequent sanctions or related actions, could adversely affect the Company’s search for an initial Business Combination and any target business with which the Company may ultimately consummate an initial Business Combination.

The holders of the founder shares, Private Placement Warrants and the Class A ordinary shares underlying such Private Placement Warrants and Private Placement Warrants and warrants that may be issued upon conversion of the Working Capital Loans will have registration rights to require the Company to register a sale of any of the Company’s securities held by them and any other securities of the Company acquired by them prior to the consummation of the initial

Note 6 — Commitments and Contingencies (cont.)

Business Combination pursuant to a registration rights agreement to be signed prior to or on the effective date of the Proposed Public Offering. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company registers such securities. In addition, the holders have certain piggyback registration rights with respect to registration statements filed subsequent to the completion of the initial Business Combination. Notwithstanding anything to the contrary, Cantor Fitzgerald & Co. may only make a demand on one occasion and only during the five-year period beginning from the commencement of sales in the Proposed Public Offering. In addition, Cantor Fitzgerald & Co. may participate in a piggyback registration only during the seven-year period beginning from the commencement of sales in the Proposed Public Offering. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriters’ Agreement

The underwriters have a 45-day option from the date of the Proposed Public Offering to purchase up to an additional 3,000,000 units to cover over-allotments, if any.

The underwriters will be entitled to a cash underwriting discount of $4,000,000 (2.0% of the gross proceeds of the units offered in the Proposed Public Offering, excluding any proceeds from units sold pursuant to the underwriters’ over-allotment option). Additionally, the underwriters will be entitled to a deferred underwriting discount of 4.0% of the gross proceeds of the Proposed Public Offering held in the Trust Account other than those sold pursuant to the underwriters’ over-allotment option and 6.0% of the gross proceeds sold pursuant to the underwriters’ over-allotment option, $8,000,000 in the aggregate (or up to $9,800,000 in the aggregate if the underwriters’ over-allotment option is exercised in full) upon the completion of the Company’s initial Business Combination subject to the terms of the underwriting agreement.

Note 7 — Shareholder’s Equity

Preference Shares — The Company is authorized to issue a total of 5,000,000 preference shares at par value of $0.0001 each. At March 31, 2026, there were no preference shares issued or outstanding.

Class A Ordinary Shares— The Company is authorized to issue a total of 500,000,000 Class A ordinary shares at par value of $0.0001 each. At March 31, 2026, there were no shares of Class A ordinary shares issued or outstanding.

Class B Ordinary Shares— The Company is authorized to issue a total of 50,000,000 Class B ordinary shares at par value of $0.0001 each. On March 31, 2026, the Company issued 5,750,000 Class B ordinary shares to the Sponsor for $25,000, or approximately $0.004 per share. The founder shares include an aggregate of up to 750,000 shares subject to forfeiture if the over-allotment option is not exercised by the underwriters in full.

The founder shares will automatically convert into Class A ordinary shares (such Class A ordinary shares delivered upon conversion will not have any redemption rights or be entitled to liquidating distributions from the Trust Account if the Company fails to consummate an initial Business Combination) concurrently with or immediately following the consummation of the initial Business Combination or earlier at the option of the holder on a one-for-one basis, subject to adjustment for share subdivisions, share capitalizations, reorganizations, recapitalizations and the like, and subject to further adjustment as provided herein. In the case that additional Class A ordinary shares, or any other equity-linked securities, are issued or deemed issued in excess of the amounts sold in this offering and related to or in connection with the closing of the initial Business Combination, the ratio at which Class B ordinary shares convert into Class A ordinary shares will be adjusted (unless the holders of a majority of the outstanding Class B ordinary shares agree to waive such 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, 20% of the sum of (i) all ordinary shares issued and outstanding upon the completion of the Proposed Public Offering (including any Class A ordinary shares issued pursuant to the underwriters’ over-allotment option and excluding the Class A ordinary shares issuable upon the exercise of the private placement warrants), plus (ii) all Class A ordinary shares and equity-linked securities issued or deemed issued, in connection with the closing of the initial Business Combination (excluding any

Note 7 — Shareholder’s Equity (cont.)

shares or equity-linked securities issued, or to be issued, to any seller in the initial Business Combination and any private placement-equivalent warrants issued to the Sponsor or any of its affiliates or to the Company’s officers or directors upon conversion of working capital loans) minus (iii) any redemptions of Class A ordinary shares by public shareholders in connection with an initial Business Combination and any redemptions of Class A ordinary shares by public shareholders in connection with any amendment to the amended and restated memorandum and articles of association made prior to the consummation of the initial Business Combination (A) to modify the substance or timing of the Company’s obligation to allow redemption in connection with the initial Business Combination or to redeem 100% of the public shares if the Company does not complete the initial Business Combination within the Completion Window or (B) with respect to any other material provisions relating to the rights of holders of Class A ordinary shares or pre-business combination activity; provided that such conversion of founder shares will never occur on a less than one-for-one basis.

Holders of record of the Company’s Class A ordinary shares and Class B ordinary shares are entitled to one vote for each share held on all matters to be voted on by shareholders. Unless specified in the amended and restated memorandum and articles of association or as required by the Companies Act or stock exchange rules, an ordinary resolution under Cayman Islands law and the amended and restated memorandum and articles of association, which requires the affirmative vote of at least a simple majority of the votes cast by such shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the applicable general meeting of the Company is generally required to approve any matter voted on by the Company’s shareholders. Approval of certain actions require a special resolution under Cayman Islands law, which (except as specified below) requires the affirmative vote of at least two-thirds of the votes cast by such shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the applicable general meeting, and pursuant to the Company’s amended and restated memorandum and articles of association, such actions include amending the amended and restated memorandum and articles of association and approving a statutory merger or consolidation with another company. There is no cumulative voting with respect to the appointment of directors, meaning, following the Company’s initial Business Combination, the holders of more than 50% of the ordinary shares voted for the appointment of directors can elect all of the directors. Prior to the consummation of the initial Business Combination, only holders of the Class B ordinary shares will (i) have the right to vote on the appointment and removal of directors and (ii) be entitled to vote on continuing the Company in a jurisdiction outside the Cayman Islands (including any special resolution required to amend the constitutional documents or to adopt new constitutional documents, in each case, as a result of approving a transfer by way of continuation in a jurisdiction outside the Cayman Islands). Holders of the Class A ordinary shares will not be entitled to vote on these matters during such time. These provisions of the amended and restated memorandum and articles of association may only be amended if approved by a special resolution passed by the affirmative vote of at least 90% (or, where such amendment is proposed in respect of the consummation of the initial Business Combination, two-thirds) of the votes cast by such shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the applicable general meeting of the Company.

Note 8 — Segment Information

FASB ASC Topic 280, “Segment Reporting,” establishes standards for companies to report in their financial statement information about operating segments, products, services, geographic areas, and major customers. Operating segments are defined as components of an enterprise for which separate financial information is available that is regularly evaluated by the Company’s chief operating decision maker (“CODM”), or group, in deciding how to allocate resources and assess performance.

The Company’s CODM has been identified as the Chief Financial Officer, who reviews the assets, operating results, and financial metrics for the Company as a whole to make decisions about allocating resources and assessing financial performance. Accordingly, management has determined that the Company only has one reportable segment.

Note 8 — Segment Information (cont.)

The CODM assesses performance for the single segment and decides how to allocate resources based on net income or loss that also is reported on the statement of operations as net income or loss. The measure of segment assets is reported on the balance sheet as total assets. When evaluating the Company’s performance and making key decisions regarding resource allocation the CODM reviews several key metrics, which include the following:

General and administrative costs are reviewed and monitored by the CODM to manage and forecast cash to ensure enough capital is available to complete a Proposed Public Offering and eventually a Business Combination within the business combination period. The CODM also reviews general and administrative costs to manage, maintain and enforce all contractual agreements to ensure costs are aligned with all agreements and budget. General and administrative costs, as reported on the statement of operations, are the significant segment expenses provided to the CODM on a regular basis.

Note 9 — Subsequent Events

The Company evaluated subsequent events and transactions that occurred after the balance sheet date through May 4, 2026, the date that the financial statements were available to be issued. Based upon this review, the Company did not identify any subsequent events that would have required adjustment or disclosure in the financial statements.

Until , 2026 (25 days after the date of this prospectus), all dealers that buy, sell or trade our units, Class A ordinary shares or public warrants, whether or not participating in this offering, may be required to deliver a prospectus.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 13. Other Expenses of Issuance and Distribution.

The estimated expenses payable by us in connection with the offering described in this registration statement (other than the underwriting discount and commissions) will be as follows:

Item 14. Indemnification of Directors and Officers.

Cayman Islands law does not limit the extent to which a company’s memorandum and articles of association may provide for indemnification of officers and directors, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against willful default, willful neglect, actual fraud or the consequences of committing a crime. Our amended and restated memorandum and articles of association will provide for indemnification of our officers and directors to the maximum extent permitted by law, including for any liability incurred in their capacities as such, except through their own actual fraud, willful default or willful neglect. We will enter into agreements with our directors and officers to provide contractual indemnification in addition to the indemnification provided for in our amended and restated memorandum and articles of association. We expect to purchase a policy of directors’ and officers’ liability insurance that insures our officers and directors against the cost of defense, settlement or payment of a judgment in some circumstances and insures us against our obligations to indemnify our officers and directors.

Our officers and directors have agreed to waive any right, title, interest or claim of any kind in or to any monies in the trust account, and have agreed to waive any right, title, interest or claim of any kind they may have in the future as a result of, or arising out of, any services provided to us and will not seek recourse against the trust account for any reason whatsoever (except to the extent they are entitled to funds from the trust account due to their ownership of public shares). Accordingly, any indemnification provided will only be able to be satisfied by us if (i) we have sufficient funds outside of the trust account or (ii) we consummate an initial business combination.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, we have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Item 15. Recent Sales of Unregistered Securities.

On March 31, 2026, FutureCorp Space Acquisition 1 LLC, paid $25,000, or approximately $0.004 per share, to cover certain of our offering costs and expenses in exchange for 5,750,000 Class B ordinary shares. Such securities were issued in connection with our organization pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act. The number of founder shares outstanding was determined based on the expectation that the total size of this offering would be a maximum of 23,000,000 units if the underwriters’ over-allotment option is exercised in full and therefore that such founder shares would represent 20% of the issued and outstanding ordinary shares upon the consummation of this offering. Up to 750,000 of these shares will be surrendered for no consideration depending on the extent to which the underwriters’ over-allotment option is exercised.

Our sponsor is an accredited investor for purposes of Rule 501 of Regulation D. Each of the equity holders in our sponsor is an accredited investor under Rule 501 of Regulation D. The sole business of our sponsor is to act as the company’s sponsor in connection with this offering. The limited liability company agreement of our sponsor provides that its membership interests may only be transferred to our officers or directors or other persons affiliated with our sponsor, or in connection with estate planning transfers.

Our sponsor and Cantor Fitzgerald & Co. have committed to, pursuant to written agreements, purchase an aggregate of 6,000,000 private placement warrants (whether or not the underwriters’ over-allotment option is exercised), each exercisable to purchase one Class A ordinary share at $11.50 per share, at a price of $1.00 per warrant, or $6,000,000 in the aggregate, in a private placement that will close simultaneously with the closing of this offering. Of those 6,000,000 private placement warrants, our sponsor has agreed to purchase 4,000,000 warrants (whether or not the underwriters’ over-allotment option is exercised) and Cantor Fitzgerald & Co. has agreed to purchase an aggregate of 2,000,000 warrants (whether or not the underwriters’ over-allotment option is exercised). This issuance will be made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act.

No underwriting discounts or commissions were paid with respect to such sales.

(a) The undersigned registrant hereby undertakes to provide to the underwriters at the closing specified in the underwriting agreement, certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

(b) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

(c) The undersigned registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) For the purpose of determining liability under the Securities Act of 1933 of any purchaser, if the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(4) For the purpose of determining liability of a registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of an undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by an undersigned registrant;
