(UNAUDITED)

Note 1 — Description of Organization, Business Operations, Liquidity and Capital Resources

HCM III Acquisition Corp. (the “Company”) is a blank check company incorporated as a Cayman Islands exempted corporation on April 15, 2025. 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 April 15, 2025 (inception) through March 31, 2026 relates to the Company’s formation, the initial public offering (“Initial Public Offering”), which is described below, and subsequent to the Initial Public Offering, identifying a target company for a Business Combination. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company generates non-operating income in the form of interest income on cash equivalents from the proceeds derived from the Initial Public Offering (as defined below). The Company has selected December 31 as its fiscal year end.

The Company’s sponsor is HCM Investor Holdings III, LLC (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on July 31, 2025. On August 4, 2025, the Company consummated the Initial Public Offering of 25,300,000 units at $10.00 per unit (the “Units”), which is discussed in Note 3, which includes the full exercise of the underwriters’ over-allotment option of 3,300,000 Units, generating gross proceeds of $253,000,000.

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of an aggregate of 4,266,667 Private Placement Warrants (the “Private Placement Warrants”) to the Sponsor and Cantor Fitzgerald & Co., the representative of the underwriters of the Initial Public Offering, at a price of $1.50 per warrant, or $6,400,000 in the aggregate. Of those 4,266,667 Private Placement Warrants, the Sponsor purchased 3,533,333 Private Placement Warrants and Cantor Fitzgerald & Co. purchased 733,334 Private Placement Warrants. Each Unit that the Company is offering has a price of $10.00 and consists of one Class A ordinary share, and one-third of one redeemable warrant. Each whole warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share.

Transaction costs amounted to $17,106,910, consisting of $4,400,000 of cash underwriting fees, $12,045,000 of deferred underwriting fees, and $661,910 of other offering costs.

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.

NOTES TO THE CONDENSED FINANCIAL STATEMENTS

MARCH 31, 2026

(UNAUDITED)

Upon the closing of the Initial Public Offering on August 4, 2025, an amount of $253,000,000 ($10.00 per Unit) from the net proceeds of the sale of the Units, and a portion of the proceeds of the sale of the Private Placement Units, is held in a Trust Account (the “Trust Account”) and will only be invested 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 held in the Trust Account that may be released to the Company to pay its taxes, if any, the proceeds from the Initial 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 Initial 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 shareholders’ rights 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), divided by the number of then outstanding public shares, subject to the limitations. The amount in the Trust Account is initially anticipated to be $10.00 per public share.

The ordinary shares subject to redemption were recorded at a redemption value and classified as temporary equity upon the completion of the Initial 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 (less taxes payable and up to $100,000 of interest to pay dissolution expenses), divided by the number of then 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 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 Initial 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, 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 Initial 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.

Liquidity, Capital Resources and Going Concern

The Company’s liquidity needs up to August 4, 2025 had been satisfied through the loan under an unsecured promissory note. As of March 31, 2026, the Company had cash of $830,149 and working capital surplus of $61,223.

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 $1.50 per warrant at the option of the lender. The warrants would be identical to the Private Placement Warrants. As of March 31, 2026 and December 31, 2025, no such Working Capital Loans were outstanding.

In connection with the Company’s assessment of going concern considerations in accordance with ASC 205-40, “Presentation of Financial Statements - Going Concern”, as of March 31, 2026, the Company may need to raise additional capital through loans or additional investments from its Sponsor, shareholders, officers, directors, or third parties. The Company’s officers, directors and Sponsor may, but are not obligated to, loan the Company funds, from time to time or at any time, in whatever amount they deem reasonable in their sole discretion, to meet the Company’s working capital needs. Accordingly, the Company may not be able to obtain additional financing. If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could include, but not necessarily be limited to, curtailing operations, suspending the pursuit of a potential transaction, and reducing overhead expenses. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all.

Management plans to address this uncertainty primarily by consummating a Business Combination. In addition, the Sponsor or its affiliates have the ability and intent, although not an obligation, to provide the Company with additional working capital loans or advances to fund operating expenses and costs related to identifying and evaluating target businesses. Based on the Company’s current liquidity position and projected operating costs, the Company may not have sufficient liquidity to meet its obligations for at least twelve months from the issuance date of the unaudited condensed financial statements. Accordingly, there is substantial doubt about the Company’s ability to continue as a going concern.

Note 2 — Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 8 of Regulation S-X of the U.S. Securities and Exchange Commission (“SEC”). Certain information or footnote disclosures normally included in unaudited condensed financial statements prepared in accordance with GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, they do not include all the information and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows. In the opinion of management, the accompanying unaudited condensed financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position, operating results and cash flows for the period presented.

The accompanying unaudited condensed financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K as filed with the SEC on March 30, 2026. The interim results for the three months ended March 31, 2026, are not necessarily indicative of the results to be expected for the year ending December 31, 2026 or for any future periods.

Emerging Growth Company

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 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 the unaudited condensed 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 unaudited condensed financial statements. Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had cash of $83,840 and $52,484 and cash equivalents of $746,309 and $962,798 as of March 31, 2026 and December 31, 2025, respectively.

Marketable Securities Held in Trust Account

As of March 31, 2026 and December 31, 2025, the assets held in the Trust Account, amounting to $259,402,294 and $257,298,929, respectively, were held in money market funds which invest in U.S. Treasury securities.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation coverage limit of $250,000. Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company’s financial condition, results of operations, and cash flows.

Offering Costs

The Company complies with the requirements of the ASC 340-10-S99 and SEC Staff Accounting Bulletin Topic 5A, “Expenses of Offering.” Offering costs consist principally of professional and registration fees that are related to the Initial Public Offering. FASB ASC 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 Initial Public Offering proceeds from the Units between Class A ordinary shares and warrants, using the residual method by allocating Initial 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 were charged to temporary equity and offering costs allocated to the Public and Private Placement Warrants were charged to shareholders’ deficit as Public and Private Placement Warrants after management’s evaluation are accounted for under equity treatment.

Fair Value of Financial Instruments

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

Income Taxes

The Company accounts for income taxes under 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.

NOTES TO THE CONDENSED FINANCIAL STATEMENTS

MARCH 31, 2026

(UNAUDITED)

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 and December 31, 2025, 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.

Class A Shares Subject to Possible Redemption

The public shares contain a redemption feature which allows for the redemption of such public shares in connection with the Company’s liquidation, if there is a shareholder vote (A) to modify the substance or timing of the Company’s obligation to allow redemption in connection with a Business Combination or to redeem 100% of the public shares if the Company does not complete an initial Business Combination within the completion window or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial Business Combination activity, or if there is a shareholder vote or tender offer in connection with the Company’s initial Business Combination. In accordance with ASC 480-10-S99, the Company classifies public shares subject to redemption outside of permanent equity as the redemption provisions are not solely within the control of the Company. The Company recognizes changes in redemption value immediately as they occur and will adjust the carrying value of redeemable shares to equal the redemption value at the end of each reporting period. Immediately upon the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption value. The change in the carrying value of redeemable shares will result in charges against additional paid-in capital (to the extent available) and accumulated deficit. Accordingly, as of March 31, 2026 and December 31, 2025, Class A ordinary shares subject to possible redemption are presented at redemption value as temporary equity, outside of the shareholders’ deficit section of the Company’s condensed balance sheets. As of March 31, 2026 and December 31, 2025, the Class A ordinary shares subject to possible redemption reflected in the condensed balance sheets are reconciled in the following table:

Gross proceeds	$	253,000,000

Class A ordinary shares subject to possible redemption, March 31, 2026	$	259,402,294

Warrant Instruments

The Company accounts for the Public and Private Warrants issued in connection with the Initial 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 classified the warrant instruments under equity treatment at their assigned values.

Net Income per Ordinary Share

The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” Net income per ordinary share is computed by dividing net income by the weighted average number of shares of ordinary shares outstanding for the period. The Company has two classes of ordinary shares, which are referred to as Class A ordinary shares and Class B ordinary shares. Accretion associated with the redeemable shares of Class A ordinary shares is excluded from income per ordinary share as the redemption value approximates fair value.

The following table reflects the calculation of basic and diluted net income per ordinary share (in dollars, except per share amounts):

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 unaudited condensed financial statements.

Note 3 — Initial Public Offering

Pursuant to the Initial Public Offering on August 4, 2025, the Company sold 25,300,000 Units at a purchase price of $10.00 per Unit for a total of $253,000,000, which includes the full exercise of the underwriters’ over-allotment option in the amount of 3,300,000 Units. Each Unit has a price of $10.00 and consists of one Class A ordinary share, and one-third of one redeemable warrant. 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 — As of March 31, 2026 and December 31, 2025, there were 8,433,333 Public Warrants 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 issue 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, 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.

(UNAUDITED)

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 Initial Public Offering or a new registration statement 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 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

Simultaneously with the closing of the Initial Public Offering, the Sponsor and Cantor Fitgerald & Co. purchased an aggregate of 4,266,667 Private Placement Warrants, each exercisable to purchase one Class A ordinary share at $11.50 per share, at a price of $1.50 per warrant, in a private placement for an aggregate purchase price of $6,400,000. Of those 4,266,667 Private Placement Warrants, the Sponsor purchased 3,533,333 Private Placement Warrants and Cantor Fitzgerald & Co. purchased 733,334 Private Placement Warrants. 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 are identical to the Public Warrants sold in the Initial 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 to private placement warrants held by Cantor Fitzgerald & Co. and/or its designees, will not be exercisable more than five years from the commencement of sales in the Initial Public Offering in accordance with Financial Industry Regulatory Authority Rule 5110(g)(8).

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 (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 shareholders’ rights 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 Initial 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 April 16, 2025, the Sponsor paid $25,000, or approximately $0.004 per share, to cover certain of the Company’s offering costs in exchange for 7,666,667 founder shares. On May 29, 2025, the Company through a share recapitalization issued an additional 766,666 Class B ordinary shares to the Sponsor and therefore the Sponsor now holds 8,433,333 founder shares, at approximately, $0.003 per share. All share and per-share data have been retrospectively presented. Up to 1,100,000 of the founder shares would be surrendered by the Sponsor for no consideration depending on the extent to which the underwriters’ over-allotment option is exercised. On August 4, 2025, simultaneously with the closing of the Initial Public Offering, the underwriters exercised their over-allotment option in full as part of the closing of the Initial Public Offering. As such, the 1,100,000 founder shares are no longer subject to forfeiture.

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

The Sponsor had agreed to loan the Company an aggregate of up to $300,000 to be used for a portion of the expenses of the Initial Public Offering. The loan was non-interest bearing, unsecured and due at the earlier of December 31, 2026 or the closing of the Initial Public Offering. On August 4, 2025, the Company repaid $248,243 of the outstanding balance of the promissory note. Borrowings under the note are no longer available.

Commencing on July 31, 2025, the Company entered into an agreement with an affiliate of the Sponsor to pay an aggregate of $15,000 per month for office space, utilities, and secretarial and administrative support. These monthly fees will cease upon the completion of the initial Business Combination or the liquidation of the Company. For the three months ended March 31, 2026, the Company incurred and paid $45,000, of which $15,000 is included in accrued expenses in the accompanying condensed balance sheet.

Advisory Agreement

The Company engaged Zenith Securities, LLC (“Zenith”), an affiliate of a passive member of the Sponsor, to provide consulting and advisory services in connection with the Initial Public Offering, for which it earned customary advisory fees. Zenith represents the Company’s interests only, is independent of the underwriters and is not a party to any securities purchase agreement with the Company, the underwriters’, or investors in relation to Initial Public Offering. Zenith’s fee is equal to 0.20% of the aggregate proceeds of the Initial Public Offering (excluding the proceeds of the exercise of the over-allotment option) net of underwriters’ out-of-pocket expenses (the “Advisor IPO Fee”).

The Company also engaged Zenith as an advisor in connection with the initial Business Combination for which it earned an advisory fee of 0.45% of the proceeds of the Initial Public Offering (including proceeds from the IPO), net of underwriter’s out-of-pocket expenses (the “Advisor IBC Fee”). The Advisor IBC Fee and any portion of the aggregate 0.65% Advisor Fee attributable to the exercise of the over-allotment option will be payable at the closing of the Company’s initial Business Combination.

The underwriters will reimburse the Company for the advisory fees paid to Zenith in connection with the Initial Public Offering and the Business Combination, as set forth in this paragraph. On August 20, 2025, the underwriters paid Zenith $367,110. As of March 31, 2026 and December 31, 2025, the advisory fee payable is $1,204,500.

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 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 $1.50 per warrant at the option of the lender. The warrants would be identical to the Private Placement Warrants. As of March 31, 2026 and December 31, 2025, 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, 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.

Registration Rights

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 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 Business Combination pursuant to a registration rights agreement signed on the effective date of the Initial 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. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriters’ Agreement

The underwriters had a 45-day option from the date of the Initial Public Offering to purchase up to an additional 3,300,000 units to cover over-allotments, if any. On August 4, 2025, simultaneously with the closing of the Initial Public Offering, the underwriters elected to fully exercise the over-allotment option to purchase the additional 3,300,000 Units at a price of $10.00 per Unit.

HCM III ACQUISITION CORP.

NOTES TO THE CONDENSED FINANCIAL STATEMENTS

(UNAUDITED)

The underwriters were entitled to a cash underwriting discount of $4,400,000 (2.0% of the gross proceeds of the units offered in the Initial Public Offering, excluding any proceeds from units sold pursuant to the underwriters’ over-allotment option), which was paid at the closing of the Initial Public Offering. Additionally, the underwriters are entitled to a deferred underwriting discount of 4.50% of the gross proceeds of the Initial Public Offering held in the Trust Account other than those sold pursuant to the underwriters’ over-allotment option and 6.50% of the gross proceeds sold pursuant to the underwriters’ over-allotment option, $12,045,000 in the aggregate upon the completion of the Company’s initial Business Combination subject to the terms of the underwriting agreement.

Note 7 — Shareholders’ Deficit

Preference Shares — The Company is authorized to issue a total of 1,100,000 preference shares at par value of $0.0001 each. As of March 31, 2026 and December 31, 2025, there were no preference shares issued or outstanding.

Class A Ordinary Shares — The Company is authorized to issue a total of 200,000,000 Class A ordinary shares at par value of $0.0001 each. As of March 31, 2026 and December 31, 2025, there were no Class A ordinary shares issued or outstanding, excluding 25,300,000 shares subject to possible redemption.

Class B Ordinary Shares — The Company is authorized to issue a total of 20,000,000 Class B ordinary shares at par value of $0.0001 each. On April 16, 2025, the Sponsor paid $25,000, or approximately $0.004 per share, to cover certain of the Company’s offering costs in exchange for 7,666,667 founder shares. On May 29, 2025, the Company through a share recapitalization issued an additional 766,666 Class B ordinary shares to the Sponsor and therefore the Sponsor now holds 8,433,333 founder shares, at approximately, $0.003 per share. All share and per-share data have been retrospectively presented. The founder shares include an aggregate of up to 1,100,000 shares subject to forfeiture if the over-allotment option is not exercised by the underwriters in full. As of March 31, 2026 and December 31, 2025, there were 8,433,333 shares of Class B ordinary shares issued and outstanding. On August 4, 2025, the underwriters exercised their over-allotment option in full as part of the closing of the Initial Public Offering. As such, the 1,100,000 founder shares are no longer subject to forfeiture.

The founder shares will automatically convert into Class A ordinary shares 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 the Initial Public 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, 25% of the sum of (i) the total number of all ordinary shares outstanding upon the completion of the Initial Public Offering (including any Class A ordinary shares issued pursuant to the underwriters’ over-allotment option and excluding the Class A ordinary shares underlying the private placement warrants issued to the Sponsor), 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 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; 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 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 — Fair Value Measurements

The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities).

The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities:

Level 1:

Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2:

Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active.

Level 3:

Unobservable inputs based on assessment of the assumptions that market participants would use in pricing the asset or liability.

The following table presents information about the Company’s assets that are measured at fair value as of March 31, 2026 and December 31, 2025 and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value:

Description	Level	March 31, 2026		December 31, 2025

The fair value of the Public Warrants issued in the Initial Public Offering is $3,078,167, or $0.365 per Public Warrant, and was determined using Monte Carlo Simulation Model. The Public Warrants issued in the Initial Public Offering have been classified within shareholders’ deficit and will not require remeasurement after issuance.

Note 9 — Segment Information

ASC Topic 280, “Segment Reporting,” establishes standards for companies to report in their financial statements 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 Executive Officer, who reviews the assets, operating results, and financial metrics for the Company as a whole to make decisions about allocating resources. Accordingly, management has determined that the Company only has one reportable segment.

HCM III ACQUISITION CORP.

NOTES TO THE CONDENSED FINANCIAL STATEMENTS

MARCH 31, 2026

(UNAUDITED)

The CODM assesses performance for the single segment and decides how to allocate resources. The measure of segment profit or loss is net income or loss as presented on the statement of operations. The measure of segment assets is reported on the condensed balance sheets 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:

	March 31,		December 31,
	2026		2025
Cash and cash equivalents	$	830,149	$	1,015,282
Marketable securities held in Trust Account	$	259,402,294	$	257,298,929

	For the Three Months Ended March 31, 2026
General and administrative costs	$	387,273
Interest earned on marketable securities held in Trust Account	$	2,103,365

The CODM reviews interest earned on the Trust Account to measure and monitor value and determine the most effective strategy of investment with the Trust Account funds while maintaining compliance with the trust agreement.

General and administrative expenses are reviewed and monitored by the CODM to manage and forecast cash to ensure enough capital is available to complete a Business Combination or similar transaction 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 unaudited condensed statement of operations, are the significant segment expenses provided to the CODM on a regular basis.

All other segment items included in net income are reported on the unaudited condensed statement of operations and described within their respective disclosures.

Note 10 — Subsequent Events

The Company evaluated subsequent events and transactions that occurred after the condensed balance sheet date through May 14, 2026, the date that the unaudited condensed 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 unaudited condensed financial statements.

Certain information contained in the discussion and analysis set forth below includes forward-looking statements that involve risks and uncertainties.

Special Note Regarding Forward-Looking Statements

This Quarterly Report includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of 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 Form 10-Q including, without limitation, statements in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations” regarding the completion of the Proposed Business Combination (as defined below), 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, including that the conditions of the Proposed Business Combination are not satisfied. 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 filed with the U.S. Securities and Exchange Commission (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.

Overview

We are a blank check company incorporated in the Cayman Islands on April 15, 2025 formed 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”). We intend to effectuate our Business Combination using cash derived from the proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, our shares, debt or a combination of cash, shares and debt.

We expect to incur significant costs in the pursuit of our acquisition plans. We cannot assure you that our plans to complete a Business Combination will be successful.

Results of Operations

We have neither engaged in any operations nor generated any revenues to date. Our only activities from April 15, 2025 (inception) through March 31, 2026 were organizational activities, those necessary to prepare for the Initial Public Offering, described below, and identifying a target company for a Business Combination. We do not expect to generate any operating revenues until after the completion of our Business Combination. Subsequent to the Initial Public Offering, we generate non-operating income in the form of interest income on marketable securities held in the Trust Account. We incur expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), as well as for due diligence expenses.

For the three months ended March 31, 2026, we had a net income of $1,724,603, which consists of interest earned on marketable securities held in Trust Account of $2,103,365 and interest earned on cash equivalents of $8,511, offset by general and administrative costs of $387,273.

Liquidity, Capital Resources and Going Concern

Until the consummation of the Initial Public Offering, our only source of liquidity was an initial purchase of shares of Class B Ordinary Shares, par value $0.0001 per share, by the Sponsor and loans from the Sponsor.

On August 4, 2025, we consummated the Initial Public Offering of 25,300,000 units at $10.00 per Units, which includes the full exercise of the underwriters’ over-allotment option of 3,300,000 Units, generating gross proceeds of $253,000,000. Simultaneously with the closing of the Initial Public Offering, we consummated the sale of an aggregate of 4,266,667 Private Placement Warrants to the Sponsor and Cantor Fitzgerald & Co., the representative of the underwriters of the Initial Public Offering, at a price of $1.50 per warrant, or $6,400,000 in the aggregate.

Following the Initial Public Offering, the full exercise of the over-allotment option, and the sale of the Units, a total of $253,000,000 was placed in the Trust Account. We incurred $17,106,910, consisting of $4,400,000 of cash underwriting fees, $12,045,000 of deferred underwriting fees, and $661,910 of other offering costs.

For the three months ended March 31, 2026, cash used in operating activities was $185,133. Net income of $1,724,603 was affected by interest earned on marketable securities held in the Trust Account of $2,103,365. Changes in operating assets and liabilities used $193,629 of cash for operating activities.

As of March 31, 2026, we had marketable securities held in the Trust Account of $259,402,294 (including approximately $2,103,365 of interest income) consisting of U.S. Treasury Bills with a maturity of 185 days or less. We may withdraw interest from the Trust Account to pay taxes, if any. We intend to use substantially all of the funds held in the Trust Account, including any amounts representing interest earned on the Trust Account (less income taxes payable), to complete our Business Combination. To the extent that our share capital or debt is used, in whole or in part, as consideration to complete our Business Combination, the remaining proceeds held in the Trust Account will be used as working capital to finance the operations of the target business or businesses, make other acquisitions and pursue our growth strategies.

As of March 31, 2026, we had cash of $830,149. We intend to use the funds held outside the Trust Account primarily to identify and evaluate target businesses, perform business due diligence on prospective target businesses, travel to and from the offices, plants or similar locations of prospective target businesses or their representatives or owners, review corporate documents and material agreements of prospective target businesses, and structure, negotiate and complete a Business Combination.

In order to fund working capital deficiencies or finance transaction costs in connection with a Business Combination, the Sponsor, or certain of our officers and directors or their affiliates may, but are not obligated to, loan us funds as may be required. If we complete a Business Combination, we would repay such loaned amounts. In the event that a Business Combination does not close, we may use a portion of the working capital held outside the Trust Account to repay such loaned amounts but no proceeds from our Trust Account would be used for such repayment. 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 $1.50 per warrant at the option of the lender. The warrants would be identical to the Private Placement Warrants.

We may need to raise additional funds in order to meet the expenditures required for operating our business. Moreover, if our estimate of the costs of identifying a target business, undertaking in-depth due diligence and negotiating a Business Combination are less than the actual amount necessary to do so, we may have insufficient funds available to operate our business prior to our Business Combination. Moreover, we may need to obtain additional financing either to complete our Business Combination or because we become obligated to redeem a significant number of our Public Shares upon consummation of our Business Combination, in which case we may issue additional securities or incur debt in connection with such Business Combination.

Off-Balance Sheet Arrangements

We have no obligations, assets or liabilities, which would be considered off-balance sheet arrangements as of March 31, 2026. We do not participate in transactions that create relationships with unconsolidated entities or financial partnerships, often referred to as variable interest entities, which would have been established for the purpose of facilitating off-balance sheet arrangements. We have not entered into any off-balance sheet financing arrangements, established any special purpose entities, guaranteed any debt or commitments of other entities, or purchased any non-financial assets.

Contractual Obligations

We do not have any long-term debt, capital lease obligations, operating lease obligations or long-term liabilities, other than an agreement with the Sponsor or an affiliate to pay an aggregate of $15,000 per month for office space, utilities, and secretarial and administrative support. These monthly fees will cease upon the completion of the initial Business Combination or the liquidation of the Company.

The underwriters were entitled to a cash underwriting discount of $4,400,000 (2.0% of the gross proceeds of the units offered in the Initial Public Offering, excluding any proceeds from units sold pursuant to the underwriters’ over-allotment option), which was paid at the closing of the Initial Public Offering. Additionally, the underwriters are entitled to a deferred underwriting discount of 4.50% of the gross proceeds of the Initial Public Offering held in the Trust Account other than those sold pursuant to the underwriters’ over-allotment option and 6.50% of the gross proceeds sold pursuant to the underwriters’ over-allotment option, or $12,045,000 in the aggregate upon the completion of the Company’s initial Business Combination subject to the terms of the underwriting agreement.

Critical Accounting Estimates

The preparation of unaudited condensed financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the unaudited condensed financial statements, and income and expenses during the periods reported. Making estimates requires management to exercise significant judgement. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the unaudited condensed financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could materially differ from those estimates. As of March 31, 2026, we did not have any critical accounting estimates to be disclosed.

Recent Accounting Standards

Management does not believe that any recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on our unaudited condensed financial statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Not required for smaller reporting companies.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are controls and other procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is accumulated and communicated to Management, including our Chief Executive Officer and Chief Financial Officer (together, the “Certifying Officers”), or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure.

As required by Rules 13a-15 and 15d-15 under the Exchange Act, our Chief Executive Officer and Chief Financial Officer carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of March 31, 2026. Based upon their evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) were effective. Accordingly, management believes that the unaudited condensed financial statements included in this Annual Report present fairly in all material respects our financial position, results of operations and cash flows for the period presented.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the fiscal quarter of 2025 covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

None

Item 1A. Risk Factors

Factors that could cause our actual results to differ materially from those in this report include the risk factors described in our Annual Report on Form 10-K filed with the SEC. As of the date of this Report, there have been no material changes to the risk factors disclosed in our Annual Report on Form 10-K filed with the SEC.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

On August 4, 2025, we consummated the Initial Public Offering of 25,300,000 units at $10.00 per Units, which includes the full exercise of the underwriters’ over-allotment option of 3,300,000 Units, generating gross proceeds of $253,000,000. Cantor acted as sole book-running manager of the Initial Public Offering. The securities in the offering were registered under the Securities Act on registration statement on Form S-1 (No. 333-287841). The Securities and Exchange Commission declared the registration statements effective on August 4, 2025.

Simultaneously with the closing of the Initial Public Offering, we consummated the sale of an aggregate of 4,266,667 Private Placement Warrants (to the Sponsor and Cantor Fitzgerald & Co., the representative of the underwriters of the Initial Public Offering, at a price of $1.50 per warrant, or $6,400,000 in the aggregate. Of those 4,266,667 Private Placement Warrants, the Sponsor purchased 3,533,333 Private Placement Warrants and Cantor Fitzgerald & Co. purchased 733,334 Private Placement Warrants. Each Unit that the Company is offering has a price of $10.00 and consists of one Class A ordinary share, and one-third of one redeemable warrant. Each whole warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share. The foregoing issuance was made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act.

The Private Warrants are identical to the warrants underlying the Units sold in the Initial Public Offering, except that the Private Warrants are not transferable, assignable or salable until after the completion of a Business Combination, subject to certain limited exceptions.

The Private Placement Warrants are identical to the warrants underlying the Units sold in the Initial Public Offering, except that the Private Placement Warrants are not transferable, assignable or salable until after the completion of a Business Combination, subject to certain limited exceptions.

Of the gross proceeds received from the Initial Public Offering and the proceeds of the sale of the Private Placement Warrants, an aggregate of $253,000,000 was placed in the Trust Account.

We paid a total of $17,106,910, consisting of $4,400,000 of cash underwriting fee, $12,045,000 of deferred underwriting fee, and $661,910 of other offering costs.
