NOTE 1 — ORGANIZATION AND BUSINESS OPERATIONS

Formation and Initial Public Offering 

Collective Acquisition Corp., (the “Company”), formerly known as Dune Acquisition Corporation II (see Note 10), is a blank check company incorporated as a Cayman Islands exempted company on September 13, 2024. 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”).

As of March 31, 2026, the Company had not commenced any operations. All activity for the period from September 13, 2024 (inception) through March 31, 2026 relates to the Company’s formation, initial public offering (the “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 on cash and cash equivalents in the form of interest income from the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end.

Prior to the Closing Date (as defined below), the Company’s Sponsor was Dune Acquisition Holdings II LLC (the “Original Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on May 6, 2025. On May 8, 2025, the Company consummated the Initial Public Offering of 14,375,000 units (the “Units”), which includes the full exercise by the underwriters of their over-allotment option in the amount of 1,875,000 Units, at $10.00 per Unit, generating gross proceeds of $143,750,000. Each Unit consists of one Class A ordinary share (“Public Share”) and three-quarters of one redeemable warrant (“Public Warrant”). Each whole warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share. Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 2,000,000 Private Placement Warrants (the “Private Placement Warrants”) to the Original Sponsor, at a price of $1.00 per warrant, generating gross proceeds of $2,000,000. The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial 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).

Transaction costs amounted to $6,637,469, consisting of $550,000 of cash underwriting fees, $5,750,000 of deferred underwriting fees and $337,469 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 of 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 is otherwise not 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.

Changes in Control of Registrant

On January 30, 2026, Collective Acquisition Sponsor LLC, a Delaware limited liability company (the “New Sponsor”), the Company, the Original Sponsor, Carter Glatt, as the managing member of the Original Sponsor (the “Sponsor Member”), certain members of the Original Sponsor named as signatories thereto (the “Non-Managing Members”) and certain other institutional investors signatories thereto (the “Non-Managing Investors”, together with the Non-Managing Members and the Sponsor Member, the “Original Sponsor Members”) entered into a Purchase and Sponsor Handover Agreement (the “Purchase Agreement”) pursuant to which the New Sponsor has agreed to purchase from the Original Sponsor, an aggregate of (i) 4,475,000 Class B ordinary shares, $0.0001 par value per share and (ii) 1,000,000 private placement warrants of the Company (the “Transferred Interests”), for an aggregate purchase price of $2,000,000 (the “Transaction”).

Pursuant to the Purchase Agreement, if a definitive business combination agreement is not entered into by May 7, 2026 (the “Option Date”), the Sponsor Member shall have the right (but not the obligation) to repurchase the Transferred Interests from the New Sponsor for a purchase price of $2,000,000 (the “Repurchase Right”). The Repurchase Right may be exercised only during the period commencing on the Option Date and ending at 5:00 p.m., New York City time, on the date that is five (5) days after the Option Date (the “Option Period”), by delivery of written notice of exercise to the New Sponsor in accordance with the terms set forth in the Purchase Agreement. If the Sponsor Member does not exercise the Repurchase Right within the Option Period, the Repurchase Right shall automatically terminate and be of no further force or effect.

The closing of the Transaction and such other transactions contemplated by the Purchase Agreement (the “Closing”) occurred on February 5, 2026 (the “Closing Date”). The Closing was conditioned upon the delivery of certain documents, as set forth in the Purchase Agreement, and upon other customary closing conditions.

Pursuant to the Purchase Agreement, among other matters, effective on the Closing Date:

On February 5, 2026, Elliot Richmond was appointed as Chief Executive Officer and Chief Financial Officer of the Company and Carter Glatt, the former Chairman and CEO of the Company, became a special advisor. On April 6, 2026, the 10th day following the mailing by the Company of an information statement to the shareholders of the Company advising them of the Transaction and the other transactions contemplated by the Purchase Agreement, including the change in control of a majority of the Board of Directors, pursuant to Section 14(f) of the Exchange Act, as amended, and Rule 14(f) thereunder (the “Schedule 14F Change in Control Date”), the existing members of the board of directors (the “Board”), Carter Glatt, Michael Castaldy, Ben Coates, Jeron Smith and Cecil White, each resigned as directors of the Company, Elliot Richmond was appointed as Chairman of the Board and David Bailin and Jeremy Sziklay were appointed as independent directors of the Board. David Bailin and Jeremy Sziklay each serve as members of the Audit Committee and the Compensation Committee.

The Trust Account and Business Combination

Following the closing of the Initial Public Offering on May 8, 2025, an amount of $144,109,375 ($10.025 per Unit) from the net proceeds of the sale of the Units and the sale of the Private Placement Warrants was held in a Trust Account (the “Trust Account”) and was initially 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; holding 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 it 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 potential status under the Investment Company Act), instruct the trustee to liquidate the investments held in the Trust Account and instead 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 for taxes payable or up to $100,000 of interest to pay dissolution expenses, 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 15 months from the closing of the Initial Public Offering or by such earlier liquidation date as the 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, regardless of whether they abstain, vote for, or against, the Company’s initial business combination, 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 (which interest shall be net of taxes payable) and not previously released to the Company, divided by the number of then outstanding public shares, subject to the limitations. The amount in the Trust Account was initially $10.025 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 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 (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter (and subject to lawfully available funds therefor), 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 (net of taxes payable and less up to $100,000 of interest to pay dissolution expenses), divided by the number of then-outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the board of directors, liquidate and dissolve, subject in each case to obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

The Original Sponsor, New 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) in favor of the initial Business Combination.

The Company’s New 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) $10.025 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 $10.025 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 New Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether the New Sponsor has sufficient funds to satisfy its indemnity obligations and the Company believes that the New Sponsor’s only assets are securities of the Company. Therefore, the Company cannot assure that the New Sponsor would be able to satisfy those obligations.

Liquidity, Capital Resources and Going Concern

As of March 31, 2026, the Company had operating cash and cash equivalents of $84,207 and a working capital surplus of $114,632. The Company intends 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 connection with the Company’s assessment of going concern considerations in accordance with ASC 205-40, “Going Concern,” as of March 31, 2026, the Company may need to raise additional capital through loans or additional investments from its New Sponsor, shareholders, officers, directors, or third parties. The Company’s officers, directors and New Sponsor may, but are not obligated to, loan funds to the Company, 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 would 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. The Company’s liquidity condition raises substantial doubt about the Company’s ability to continue as a going concern for a period of time within one year after the date that the accompanying unaudited condensed financial statements are issued. Management plans to address this uncertainty through a Business Combination.

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES

NOTE 3 — INITIAL PUBLIC OFFERING

Pursuant to the Initial Public Offering on May 8, 2025, the Company sold 14,375,000 Units at a purchase price of $10.00 per Unit, generating gross proceeds of $143,750,000. Each Unit consists of one Class A ordinary share and three-quarters 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, subject to adjustment. Each warrant will become exercisable on the later of 30 days after the completion of the initial Business Combination or 12 months from the closing of the Initial Public Offering and will expire seven years after the completion of the initial Business Combination, or earlier upon redemption or liquidation.

Warrants — As of March 31, 2026 and December 31, 2025, there were 12,781,250 warrants outstanding, including 10,781,250 public warrants and 2,000,000 Private Placement Warrants.

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, or a valid exemption from registration is available. 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, or a valid exemption from registration is not available, 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 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:

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 on May 8, 2025, the Original Sponsor purchased an aggregate of 2,000,000 Private Placement Warrants at a price of $1.00 per warrant, generating gross proceeds of $2,000,000. 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. On the Closing Date, pursuant to the Purchase Agreement, the Original Sponsor sold 1,000,000 private placement warrants of the Company to the New Sponsor.

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 Original Sponsor, the underwriters, 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 and (ii) will be entitled to registration rights.

NOTE 5 — RELATED PARTY TRANSACTIONS

Founder Shares

On September 27, 2024, the Original 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 6,900,000 founder shares to the Original Sponsor. On April 22, 2025, the Original Sponsor surrendered 1,150,000 Class B ordinary shares, where the number of outstanding founder shares was reduced to 5,750,000 in the aggregate. All share and per share data has been retrospectively presented. Up to 750,000 of the founder shares may be surrendered by the Original Sponsor for no consideration if the underwriters’ over-allotment is not fully exercised. On May 8, 2025, the underwriters exercised their over-allotment option in full as part of the closing of the Initial Public Offering. As such, the 750,000 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 Original Sponsor had agreed to loan the Company an aggregate of up to $150,000, as amended, 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, 2025 or the closing of the Initial Public Offering. As of May 8, 2025, the Company had borrowed $150,000 under the promissory note. This amount was repaid at the close of the Initial Public Offering and borrowings under this note are no longer allowed.

Administrative Services Agreement

Commencing on the effective date of the Initial Public Offering, May 6, 2025, the Company entered into an agreement with the Original Sponsor and subsequently New Sponsor or an affiliate of the New Sponsor to pay an aggregate of $15,000 per month for utilities and secretarial and administrative support. Upon completion of a Business Combination or its liquidation, the Company will cease paying these monthly fees. For the three months ended March 31, 2026 the Company incurred and paid $45,000 for these fees. There were no fees incurred or paid during the three months ended March 31, 2025

Working Capital Loans

In order to fund working capital deficiencies or finance transaction costs in connection with a Business Combination, following the Closing Date, the New Sponsor or an affiliate of the New 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 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 military escalations between the United States and Iran, the ongoing Russia-Ukraine conflict and the Israel-Hamas conflict. Ongoing military escalation between the United States and Iran has heightened risks to critical infrastructure, shipping routes, and energy supplies. Any further deterioration could drive sustained increases in oil prices, disrupt global trade, contribute to macroeconomic instability, and materially heighten the risk of a global recession. 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 Middle East 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, Iran, 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 these geopolitical conditions could reduce the pool of viable attractive target candidates for our initial business combination, the military escalations between the United States and Iran, 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.

Registration Rights

The holders of the (i) founder shares, which were issued in a private placement prior to the closing of the Initial Public Offering, (ii) private placement warrants which will be issued in a private placement simultaneously with the closing of the Initial Public Offering and the Class A ordinary shares underlying such private placement warrants and (iii) private placement warrants that may be issued upon conversion of working capital loans have registration rights to require the Company to register a sale of any of its securities held 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.

Underwriting Agreement

The underwriters were granted a 45-day option from the date of the Initial Public Offering to purchase up to an additional 1,875,000 units to cover over-allotments, if any. On May 8, 2025, the underwriters exercised their over-allotment option, closing on the 1,875,000 additional units simultaneously with the Initial Public Offering.

The underwriters were entitled to an underwriting discount of $550,000 which was paid in cash upon the closing of the Initial Public Offering.

In addition, the underwriters are also entitled to a deferred underwriting discount of $0.40 per unit, or up to $5,750,000, payable to the underwriters for deferred underwriting commissions and will be placed in the Trust Account. The $0.40 per unit will become payable to the underwriters from the amounts held in the Trust Account solely on amounts remaining in the Trust Account following all properly submitted shareholder redemption in connection with the consummation of the initial Business Combination.

Deferred Consulting Fees

On February 11, 2026, the Company entered into an agreement with the proxy solicitor to provide special meeting proxy solicitation agent services. All Fees pursuant to that agreement are due to be paid at closing of the Business Combination. As of and for the three months ended March 31, 2026, the Company incurred $45,000 of deferred fees under this agreement which are classified as a non-current liability in the accompanying condensed balance sheets.

Deferred Legal Fees

As of March 31, 2026 and December 31, 2025, the Company had incurred a total of $366,068 and $0, respectively, of deferred legal fees to be paid to the Company’s legal advisor upon consummation of the Business Combination. The deferred fees are classified as a non-current liability in the accompanying condensed balance sheets.

Representative Shares

The Company issued 107,813 Class A ordinary shares (“Representative Shares”) to the underwriter or its designee, for nominal consideration. With regard to the Representative Shares, the underwriters have agreed (i) not to transfer, assign or sell any such shares without the Company’s written consent until the completion of the initial Business Combination, (ii) to waive their redemption rights (or right to participate in any tender offer) with respect to such shares in connection with the completion of the initial Business Combination, and (iii) to waive their rights to liquidating distributions from the Trust Account with respect to such shares if the Company does not complete its initial Business Combination within 15 months from the closing of the Initial Public Offering.

The Representative Shares have been deemed compensation by FINRA and are therefore subject to a lock-up for a period of 180 days immediately following the commencement of sales of the Initial Public Offering. Pursuant to FINRA Rule 5110(e)(1), these securities may not be sold, transferred, assigned, pledged or hypothecated nor may they be the subject of any hedging, short sale, derivative, put or call transaction that would result in the economic disposition of the securities by any person for a period of 180 days immediately following the commencement of the Initial Public Offering except to any underwriter and selected dealer participating in the Initial Public Offering and their officers or partners, registered persons or affiliates or as otherwise permitted under FINRA Rule 5110(e)(2).

NOTE 7 — SHAREHOLDERS’ DEFICIT

Preference Shares — The Company is authorized to issue a total of 1,000,000 preference shares at par value of $0.0001 each. At 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 ordinary shares at par value of $0.0001 each. At March 31, 2026 and December 31, 2025, there were 107,813 Class A ordinary shares issued and outstanding, excluding 14,375,000 Class A ordinary 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 September 27, 2024, the Company issued 6,900,000 Class B ordinary shares to the Original Sponsor for $25,000, or approximately $0.004 per share. On April 22, 2025, the Original Sponsor surrendered 1,150,000 Class B ordinary shares, where the number of outstanding founder shares was reduced to 5,750,000 in the aggregate. All share and per share data have been retrospectively presented. The founder shares included an aggregate of up to 750,000 Class B ordinary shares subject to forfeiture if the over-allotment option is not exercised by the underwriters in full. On May 8, 2025, the underwriters exercised their over-allotment option in full as part of the closing of the Initial Public Offering. As such, the 750,000 founder shares are no longer subject to forfeiture. At March 31, 2026 and December 31, 2025, there were 5,750,000 Class B ordinary shares issued and outstanding.

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. 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, 28.4% of the sum of (i) the total number of all Class A 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 Original Sponsor or any of its affiliates or to officers and 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 Company’s amended and restated memorandum and articles of association, which requires the affirmative vote of 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, voting together as a single class, and includes a unanimous written resolution. Approval of certain actions requires a special resolution under Cayman Islands law, which (except as specified below) requires the affirmative vote of a majority 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 of the Company, and pursuant to the 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 initial Business Combination, the holders of more than 50% of 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:

The Public Warrants were valued using a Monte-Carlo methodology. The Public Warrants have been classified within shareholders’ deficit and will not require remeasurement after issuance. On May 9, 2025, a fair value of $0.09 per Public Warrant was determined. The following table presents the quantitative information regarding market assumptions used in the valuation of the Public Warrants:

NOTE 9 — SEGMENT REPORTING

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 a group that includes the Company’s Chief Financial Officer and Chief Executive Officer, that collectively review the operating results 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 operating segment.

The key measures of segment profit or loss reviewed by our CODM are interest earned on the Trust Account and formation and general and administrative expenses. The CODM reviews interest earned on the Trust Account to measure and monitor shareholder value and determine the most effective strategy of investment with the Trust Account funds while maintaining compliance with the trust agreement. Formation and 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 within the business combination period. The CODM also reviews formation and general and administrative costs to manage, maintain and enforce all contractual agreements to ensure costs are aligned with all agreements and budget.

NOTE 10 — SUBSEQUENT EVENTS 

The Company evaluated subsequent events and transactions that occurred after the condensed balance sheet date up to the date that the unaudited condensed financial statements were issued. Based upon this review, other than as described below or within these unaudited condensed financial statements, the Company did not identify any subsequent events that would have required adjustment or disclosure in the unaudited condensed financial statements.

Change in Officers, Directors and Company Name

Effective as of April 6, 2026, the existing members of the board of directors (the “Board”), Carter Glatt, Michael Castaldy, Ben Coates, Jeron Smith and Cecil White, each resigned as directors of the Company and Elliot Richmond was appointed Chairman of the Board and David Bailin and Jeremy Sziklay were appointed as independent directors of the Board. David Bailin and Jeremy Sziklay each serve as members of the Audit Committee and the Compensation Committee.

On April 21, 2026, the Company held an extraordinary general meeting to approve the change of the name of the Company from “Dune Acquisition Corporation II” to “Collective Acquisition Corp.” and an amendment to the Company’s Amended and Restated Memorandum and Articles of Association to reflect the change of name of the Company (the “Name Change Proposal”). The Name Change Proposal was approved and a copy of such amendment was included in the Company’s Current Report on Form 8-K as filed with the SEC on April 27, 2026.
