NOTE 1 — DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS

Plum Acquisition Corp. IV (the “Company” or “Plum IV”) is a blank check company incorporated as a Cayman Islands exempted corporation on June 10, 2024. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (“Business Combination”).

The Company is not limited to a particular industry or geographic region for purposes of completing a Business Combination. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies.

As of June 30, 2026, the Company had not commenced any operations. All activity for the period from June 10, 2024 (inception) through June 30, 2026 relates to the Company’s formation and the initial public offering (“Initial Public Offering”), which is described below, and, after 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 a Business Combination, at the earliest. The Company will generate non-operating income 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.

The registration statement for the Company’s Initial Public Offering was declared effective on January 14, 2025. On January 16, 2025, the Company consummated the Initial Public Offering of 17,250,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units being offered, the “Public Shares”), which included the full exercise by the underwriters of their over-allotment option in the amount of 2,250,000 Units, at $10.00 per Unit, generating gross proceeds of $172,500,000, which is discussed in Note 3.

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of an aggregate of 672,875 private placement units (each, a “Private Placement Unit”) at a price of $10.00 per Private Placement Unit, generating gross proceeds of $6,728,750, as follows: (i) by and among the Company and each of the underwriters for the purchase by the underwriters of an aggregate of 232,875 private placement units for an aggregate purchase price of $2,328,750 and (ii) by and between the Company and Plum Partners IV, LLC (the “Sponsor”) for the purchase by the Sponsor of an aggregate of 440,000 private placement units and 570,000 restricted Class A ordinary shares for an aggregate purchase price of $4,400,000. The private placement units are identical to the units sold in this offering, subject to certain limited exceptions as described in the prospectus.

Transaction costs amounted to $10,932,289, consisting of $3,450,000 of cash underwriting fee, $6,900,000 of deferred underwriting fee, and $582,289 of other offering costs.

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Securities, although substantially all of the net proceeds are intended to be applied generally toward completing a Business Combination. The Company must complete its initial Business Combination with one or more target businesses that together have a fair market value equal to at least 80% of the net assets held in the Trust Account (as defined below) (excluding any deferred underwriting commissions held in the Trust Account) at the time of the agreement to enter into a Business Combination. The Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the issued and outstanding voting securities of the target or otherwise acquires a controlling interest in the target business 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.

Following the closing of the Initial Public Offering, on January 16, 2025, an amount of $174,225,000 ($10.10 per Unit) from the net proceeds of the sale of the Units and the sale of the Private Placement Securities was placed in the trust account (the “Trust Account”) and invested or held in either (i) U.S. government treasury bills with a maturity of 185 days or less or in money market funds investing solely in U.S. Treasuries, (ii) uninvested cash, or (iii) an interest bearing bank demand deposit account or other accounts at a bank, as determined by the Company, until the earlier of: (i) the completion of a Business Combination or (ii) the distribution of the funds in the Trust Account to the Company’s shareholders, as described below. No later than 18 months after the closing of the Initial Public Offering or such earlier liquidation date as the Company’s board of directors may approve, or such later time as provided for in any amendment to the Company’s Amended and Restated Memorandum and Articles of Association (an “Extension Period”), subject to applicable law, the amounts held in the Trust Account are held as cash or cash items, including in demand deposit accounts.

(UNAUDITED)

The Company will provide its shareholders with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a general meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a Business Combination or conduct a tender offer will be made by the Company. The shareholders will be entitled to redeem their shares for a pro rata portion of the amount held in the Trust Account (initially $10.10 per share), calculated as of two business days prior to the completion of a Business Combination, including any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations. There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s public warrants.

If the Company seeks shareholder approval in connection with a Business Combination, it receives an ordinary resolution under Cayman Islands law approving a Business Combination, which requires the affirmative vote of a majority of the shareholders who vote at a general meeting of the Company. If a shareholder vote is not required under applicable law or stock exchange listing requirements and the Company does not decide to hold a shareholder vote for business or other reasons, the Company will, pursuant to its Amended and Restated Memorandum and Articles of Association, conduct the redemptions pursuant to the tender offer rules of the Securities and Exchange Commission (“SEC”), and file tender offer documents containing substantially the same information as would be included in a proxy statement with the SEC prior to completing a Business Combination.

If the Company seeks shareholder approval in connection with a Business Combination, the Sponsor has agreed to vote its Founder Shares (as defined in Note 5) and any Public Shares purchased in or after the Initial Public Offering in favor of approving a Business Combination and to waive its redemption rights with respect to any such shares in connection with a shareholder vote to approve a Business Combination. Additionally, each public shareholder may elect to redeem its Public Shares, without voting, and if they do vote, irrespective of whether they vote for or against a proposed Business Combination.

Notwithstanding the foregoing, if the Company seeks shareholder approval of a Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the Company’s Amended and Restated Memorandum and Articles of Association provides that a public shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the Public Shares without the Company’s prior written consent.

The Sponsor has agreed to (i) waive its redemption rights with respect to its private placement shares in connection with the completion of the initial business combination, (ii) waive its redemption rights with respect to its private placement shares in connection with a shareholder vote to approve an amendment to the amended and restated memorandum and articles of association (A) to modify the substance or timing of the obligation to allow redemption in connection with the initial Business Combination or to redeem 100% of the public shares if the Company fails to complete the initial Business Combination within 18 months from the closing of the Initial Public Offering or such earlier liquidation date as the Company’s board of directors may approve, or during any Extension Period, subject to applicable law or (B) with respect to any other provision relating to shareholders’ rights or pre-initial business combination activity and (iii) waive its rights to liquidating distributions from the Trust Account with respect to its private placement shares if the Company fails to complete the initial Business Combination within the prescribed timeframe. In addition, the Sponsor has agreed to vote any private placement shares held by it in favor of the initial Business Combination.

The Company will have until 18 months from the closing of the Initial Public Offering (the “Combination Period”) to complete a Business Combination. If the Company is unable to complete a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than 10 business days thereafter, redeem 100% of the outstanding Public Shares, at a per-share price, payable in cash, including interest earned on the funds held in the Trust Account (which interest shall be net of taxes payable and up to $100,000 of interest to pay dissolution expenses) and not previously released to the Company to pay its taxes, if any, 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 liquidation distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the Company’s board of directors, liquidate and dissolve, subject in each case to its obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

The Sponsor has agreed to waive its liquidation rights with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the Sponsor acquires Public Shares in or after the Initial Public Offering, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period. The underwriters have agreed to waive their rights to their deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than the initial amount held in the Trust Account ($10.10).

The 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 by a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (1) $10.10 per Public Share or (2) such lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of trust assets, in each case net of the amount of interest which may be withdrawn to pay taxes. This liability will not apply with respect to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account 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”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (other than the Company’s independent auditors), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

On July 10, 2026, the Company held an extraordinary general meeting of its shareholders (the “Shareholder Meeting”) to amend the Company’s amended and restated memorandum and articles of association (the “Articles”) to extend the date (the “Termination Date”) by which the Company has to consummate a business combination (the “Articles Extension”) from July 16, 2026 to January 16, 2027 (the “Articles Extension Date”) and to allow Plum IV, without another shareholder vote, to elect to extend the Termination Date to consummate a Business Combination on a monthly basis for up to six times by an additional one month each time after the Articles Extension Date, by resolution of the Company’s board of directors if requested by the Sponsor and upon five days’ advance notice prior to the applicable Termination Date, until July 16, 2027, or a total of up to twelve months after the Termination Date, unless the closing of a business combination shall have occurred prior to such date (the “Extension Amendment Proposal”).

In connection with the vote to approve the Extension Amendment Proposal, the holders of 13,540,384 Public Shares properly exercised their right to redeem their shares for cash at a redemption price of approximately $10.71 per share, for an aggregate redemption amount of approximately $145 million, leaving approximately $39.7 million in the Trust Account.

The Company contemplates raising private investment in public equity (“PIPE”) financing in connection with the proposed Business Combination to satisfy the minimum cash condition under the Business Combination Agreement. Accordingly, management does not believe that the reduction in the funds remaining in the Trust Account as a result of these redemptions will adversely affect the Company’s ability to satisfy the minimum cash condition, provided that the anticipated PIPE financing is successfully completed.

Proposed Business Combination

Business Combination Agreement

On March 8, 2026, the Company entered into a business combination agreement (the “Business Combination Agreement”) by and among the Company, Plum IV Merger Sub, Inc., a Delaware corporation and a direct wholly owned subsidiary of the Company (“Merger Sub”), and Controlled Thermal Resources Holdings Inc., a Delaware corporation (“CTR”), pursuant to which, among other things and subject to the terms and conditions contained therein, Merger Sub will merge with and into CTR (the “Merger”), with CTR continuing as the surviving company. The transactions contemplated by the Business Combination Agreement are referred to in this Quarterly Report as the “Business Combination.” The combined company’s business is expected to continue to operate through CTR. The proposed Merger is expected to be consummated after receipt of the required approvals by the Company’s shareholders and CTR’s stockholders and the satisfaction or waiver of certain other customary conditions.

Domestication

At least two (2) business days prior to the Closing Date (as defined in the Business Combination Agreement), subject to the satisfaction or waiver of the conditions of the Business Combination Agreement, the Company will transfer by way of continuation from the Cayman Islands to the State of Delaware and domesticate as a Delaware corporation (“Domesticated Plum IV”) in accordance with Section 388 of the General Corporation Law of the State of Delaware, as amended, and Part 12 of the Companies Act (as revised) of the Cayman Islands (such continuation and domestication, the “Domestication”).

By virtue of the Domestication upon its effectiveness, (a) each then issued and outstanding Class A ordinary share, par value $0.0001 per share, of the Company (each a “Class A Ordinary Share”) (other than any Class A Ordinary Share included in the Cayman Purchaser Units (as defined in the Business Combination Agreement)) shall convert automatically, on a one-for-one basis, into one (1) share of common stock of Domesticated Plum IV (the “Domesticated Purchaser Common Stock”); (b) each then issued and outstanding Class B ordinary share, par value $0.0001 per share, of the Company (each a “Class B Ordinary Share”) shall convert automatically, on a one-for-one basis, into one (1) share of Class B common stock of Domesticated Plum IV (the “Domesticated Purchaser Class B Common Stock”); (c) each then issued and outstanding warrant of the Company (other than any Cayman Purchaser Public Warrants (as defined in the Business Combination Agreement)) included in the Cayman Purchaser Units) (each a “Cayman Purchaser Warrant”) shall convert automatically into a warrant to acquire one (1) share of Domesticated Purchaser Common Stock (each a “Domesticated Purchaser Warrant”), pursuant to the Warrant Agreement (as defined in the Business Combination Agreement); and (d) each then issued and outstanding Cayman Purchaser Unit shall be cancelled and will thereafter entitle the holder thereof to one (1) share of Domesticated Purchaser Common Stock and one-half of one (1) Domesticated Purchaser Warrant, in each case without any action on the part of the Company, Merger Sub, the Company or any holder of securities of any of the foregoing.

The Merger and Consideration

Following the Domestication, at the Effective Time (as defined in the Business Combination Agreement), by virtue of the Merger, each share of capital stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall be automatically cancelled and extinguished and converted into one (1) share of common stock, par value $0.0001 per share, of the surviving company.

Subject to, and in accordance with the terms and conditions of the Business Combination Agreement, at the Effective Time (as defined in the Business Combination Agreement):

(vi)

each share of common stock of CTR (the “CTR Common Stock”) issued and outstanding (or deemed to be issued and outstanding under the terms of the Business Combination Agreement) immediately prior to the Effective Time, except for (a) shares held by the Company or Merger Sub (or any subsidiaries of the Company), (b) shares held by the CTR as treasury stock, if any (each share covered in subclause (a) and (b), an “Excluded Share”), (c) shares held by stockholders who have properly exercised and not withdrawn appraisal rights under Delaware law (the “Dissenting Shares”), and (d) shares of CTR Common Stock issued pursuant to an award of restricted stock that is, as of immediately prior to the Closing Date (as defined in the Business Combination Agreement), subject to a substantial risk of forfeiture and is not transferable (the “CTR Restricted Shares”), will be cancelled and converted into the right to receive the Per Share Merger Consideration (as defined in the Business Combination Agreement);

(vii)

each Excluded Share shall be automatically cancelled and retired without any conversion thereof and shall cease to exist, and no consideration shall be delivered in exchange therefor;

(viii)

each option to purchase shares of the CTR Common Stock (the “CTR Option”) that is outstanding immediately prior to the Effective Time will be automatically assumed by Domesticated Plum IV and converted into an option to purchase a number of shares of Domesticated Purchaser Common Stock equal to the product (rounded down to the nearest whole number) of (x) the number of shares of CTR Common Stock subject to such CTR Option immediately prior to the Effective Time and (y) the Exchange Ratio (as defined in the Business Combination Agreement), at an exercise price per share (rounded up to the nearest whole cent) equal to the quotient of (A) the exercise price per share of such CTR Option immediately prior to the Effective Time divided by (B) the Exchange Ratio;

(ix)

each award of the CTR Restricted Shares (the “CTR Restricted Share Award”) that is outstanding immediately prior to the Effective Time will be automatically assumed by Domesticated Plum IV such that each CTR Restricted Share Award will be converted into an award for a number of restricted shares of Domesticated Purchaser Common Stock equal to the product (rounded down to the nearest whole number) of (x) the number of shares of CTR Restricted Shares and (y) the Exchange Ratio; and

(x)

each warrant to purchase shares of the CTR Common Stock (the “CTR Warrant”) that is outstanding immediately prior to the Effective Time will be automatically assumed by the Domesticated Plum IV such that, as of the Effective Time, each CTR Warrant shall instead be converted into a warrant to purchase a number of shares of Domesticated Purchaser Common Stock equal to the product (rounded down to the nearest whole number) of (x) the number of shares of CTR Common Stock issuable upon exercise of such CTR Warrant and (y) the Exchange Ratio, at an exercise price per share (rounded up to the nearest whole cent) equal to the quotient of (A) the exercise price per share of such CTR Warrant immediately prior to the Effective Time divided by (B) the Exchange Ratio.

The Class B Conversion

At the Effective Time, by virtue of the Merger and the applicable provisions of the certificate of incorporation of Domesticated Plum IV (the “Domesticated Purchaser Charter”), each share of Domesticated Purchaser Class B Common Stock then issued and outstanding shall be automatically cancelled and extinguished and converted into one (1) share of Domesticated Purchaser Common Stock.

Amendments to Business Combination Agreement

On May 15, 2026, the Company and Merger Sub entered into an amendment to the Business Combination Agreement (the “First BCA Amendment”), which amends the Business Combination Agreement to, among other things, (i) extend the date by which the Company is required to deliver financial statements and pro forma financial information of the Company required to be included in the proxy statement/prospectus in the Registration Statement on Form S-4 from May 15, 2026 to June 15, 2026 and June 30, 2026, respectively; (ii) extend the date by which the Company and Merger Sub are required to make any filings or applications required under antitrust laws with respect to the Business Combination Agreement from April 17, 2026 to July 31, 2026; and (iii) extend the dates by which the Company is required to deliver certain material consents from May 7, 2026 to the dates listed on Schedule 8.01(m) to the Business Combination Agreement.

(UNAUDITED)

On July 6, 2026, the Company and Merger Sub entered into a second amendment to the Business Combination Agreement (the “Second BCA Amendment” and the Business Combination Agreement, as amended by the First BCA Amendment and the Second BCA Amendment, the “Amended BCA”), which amends the Business Combination Agreement to, among other things, (i) reduce the aggregate number of potential earnout shares issuable to the Company’s shareholders following the closing from 100,000,000 to 70,000,000, with each of the eight earnout tranches reduced proportionally from 12,500,000 to 8,750,000 shares; (ii) extend the date by which the parties are required to make any filings or applications required under antitrust laws with respect to the transactions contemplated by the Amended BCA from July 31, 2026 to September 30, 2026; (iii) increase the maximum number of shares issuable to Sponsor as reimbursement for founder shares issued to the Company’s shareholders, or issuable to the Company’s shareholders, who agree not to redeem their shares from 2,000,000 to 3,000,000; (iv) extend the date by which the closing must occur from December 31, 2026 to April 30, 2027; (v) reduce the valuation used to calculate the merger consideration from $4,500,000,000 to $3,150,000,000; and (vi) extend the deadlines by which the Company is required to deliver certain material consents to the dates listed on Schedule 8.01(m) to the Amended BCA.

Transaction Support Agreement

Simultaneously with the execution and delivery of the Business Combination Agreement, the Company and certain stockholders of CTR, who collectively have the right to cast at least 60% of the votes entitled to be cast at a special meeting of CTR’s stockholders (collectively, the “Supporting CTR Stockholders”) entered into a Transaction Support Agreement (the “Transaction Support Agreement”), pursuant to which the Supporting CTR Stockholders have agreed, among other things, to vote all of their shares of CTR’s common stock in favor of adopting and approving the Business Combination Agreement and the Business Combination.

Registration Rights Agreement

In connection with the Business Combination, simultaneously with the closing of the Business Combination (the “Closing”), the Company and certain holders will enter into an amended and restated Registration Rights Agreement (the “Amended and Restated Registration Rights Agreement”) that amends and restates the Registration Rights Agreement, dated January 14, 2025, by and among the Company, the Sponsor and certain other security holders named therein, pursuant to which, among other things, (i) the Company will agree to file, as soon as practicable (and in any event within thirty (30) calendar days) following the closing date, a registration statement covering the resale of certain equity securities held by the Sponsor and such other securityholders parties thereto; and (ii) such holders of registrable securities will be granted certain takedown, demand, block trade and piggyback registration rights with respect to their registrable securities, in each case, on the terms and subject to the conditions set forth in the Amended and Restated Registration Rights Agreement.

Lock-Up Agreement

In connection with the Business Combination, simultaneously with the closing, the Company, the Sponsor and certain stockholders of CTR (such holders, collectively, the “Lock-Up Parties”) will enter into a Lock-Up Agreement (the “Lock-Up Agreement”). The Lock-Up Agreement will provide that, during the applicable Lock-Up Period (as defined in the Lock-Up Agreement), subject to certain exceptions, the Lock-Up Parties will not, with respect to the Lock-Up Securities (as defined in the Lock-Up Agreement), (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent position or liquidation with respect to or decrease a call equivalent position, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any security, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (iii) publicly announce the intention to effect any transaction specified in clause (i) or (ii).

Risks and Uncertainties

The Company’s ability to complete an initial Business Combination may be adversely affected by various factors, many of which are beyond the Company’s control. The Company’s ability to consummate an initial Business Combination could be impacted by, among other things, changes in laws or regulations, downturns in the financial markets or in economic conditions, inflation, fluctuations in interest rates, increases in tariffs, supply chain disruptions, declines in consumer confidence and spending, public health considerations, and geopolitical instability, such as the military conflicts in Ukraine and the Middle East. The Company cannot at this time predict the likelihood of one or more of the above events, their duration or magnitude or the extent to which they may negatively impact the Company’s ability to complete an initial Business Combination.

NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited condensed consolidated 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 SEC. Certain information or footnote disclosures normally included in unaudited condensed consolidated 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 consolidated 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 periods presented.

PLUM ACQUISITION CORP. IV
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
JUNE 30, 2026
(UNAUDITED)

The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, as filed with the SEC on March 31, 2026. The interim results for the three and six months ended June 30, 2026 are not necessarily indicative of the results to be expected for the year ending December 31, 2026 or for any future periods.

Principles of Consolidation

Plum IV Merger Sub, Inc. (“Merger Sub”) was incorporated in Delaware on March 4, 2026, and was formed for the purpose of merging with the Company prior to the transactions contemplated in the Business Combination Agreement to facilitate the consummation of the proposed Business Combination. The Company has one wholly owned subsidiary, Merger Sub.

The accompanying consolidated financial statements include the accounts of the Company and Merger Sub. All significant intercompany balances and transactions have been eliminated in consolidation.

Liquidity and Going Concern

As of June 30, 2026, the Company had $288,518 in cash and cash equivalents and working capital deficit of $1,421,716. Further, the Company has incurred and expects to continue to incur significant costs in pursuit of its acquisition plans. There is no assurance that the Company’s plans to raise capital will be successful. Further, the Company has until January 16, 2027 to complete its initial business combination or it will liquidate absent any shareholder approved extensions (see Note 10). In connection with the Company’s assessment of going concern considerations in accordance with Accounting Standards Codification (“ASC”) Topic 205-40, “Presentation of Financial Statements - Going Concern,” as of June 30, 2026, management has determined that mandatory liquidation, should a Business Combination not occur, and potential subsequent dissolution and the liquidity condition issue raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date the unaudited condensed consolidated financial statements are issued.

No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after the Combination Period. The Company cannot assure that its plans to raise capital or to consummate an Initial Business Combination will be successful.

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 of 2002, 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 unaudited condensed consolidated 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 unaudited condensed consolidated 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 consolidated financial statements and the reported amounts of expenses during the reporting periods.

Making estimates requires management to exercise significant judgment. 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 consolidated 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 differ significantly 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 $30,000 in cash as of June 30, 2026 and December 31, 2025. The Company had $258,518 and $266,249 in cash equivalents as of June 30, 2026 and December 31, 2025, respectively.

Investments Held in Trust Account

As of June 30, 2026 and December 31, 2025, the investments held in the Trust Account, amounting to $184,416,026 and $181,285,220, were held in U.S. government treasury bills, respectively.

On July 10, 2026, in connection with the vote to approve the Extension Amendment Proposal, the holders of 13,540,384 Public Shares properly exercised their right to redeem their shares for cash at a redemption price of approximately $10.71 per share, for an aggregate redemption amount of approximately $145 million, leaving approximately $39.7 million in the trust account (see Note 10).

Offering Costs

The Company complies with the requirements of the Financial Accounting Standards Board (“FASB”) 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 directly 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 Public Shares were charged to temporary equity, and offering costs allocated to Public Warrants (as defined below) and Private Placement Units and Restricted Shares were charged to shareholders’ deficit as the Public and Private Placement Warrants (as defined below), after management’s evaluation, were accounted for under equity treatment.

Income Taxes

The Company accounts for income taxes under ASC 740, “Income Taxes” (“ASC 740”). ASC 740 requires the recognition of deferred tax assets and liabilities for both the expected impact of differences between the unaudited condensed consolidated financial statements and tax basis of assets and liabilities and for the expected future tax benefit to be derived from tax loss and tax credit carry forwards. ASC 740 additionally requires a valuation allowance to be established when it is more likely than not that all or a portion of deferred tax assets will not be realized.

ASC 740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s unaudited condensed consolidated financial statements and prescribes a recognition threshold and measurement process for unaudited condensed consolidated financial statements recognition and measurement of a tax position 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 recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of June 30, 2026 and December 31, 2025. 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 has been subject to income tax examinations by major taxing authorities since inception.

The Company is considered an exempted Cayman Islands Company 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 periods presented.

Net Income per Ordinary Share

Net income per ordinary share is computed by dividing net income by the weighted average number of ordinary shares issued and outstanding during the period, excluding ordinary shares subject to forfeiture. Weighted average shares were reduced for the effect of an aggregate of 750,000 Class B ordinary shares that were subject to forfeiture depending on the extent to which the underwriters’ over-allotment option is exercised (see Note 5). As of June 30, 2026 and June 30, 2025, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into ordinary shares and then share in the earnings of the Company. As a result, diluted income per ordinary share is the same as basic income per ordinary share for the period presented.

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 Depository Insurance Corporation coverage 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.

Fair Value of Financial Instruments

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

Warrant Instruments

The Company will account for the Public and Private Placement Warrants issued in connection with the Initial Public Offering, on January 16, 2025 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.

PLUM ACQUISITION CORP. IV
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
JUNE 30, 2026
(UNAUDITED)

The fair value of the Public Warrants was $603,750, or $0.04 per Public Warrant. The fair value of Public Warrants was determined using Monte Carlo Simulation Model. The Public Warrants have been classified within shareholders’ deficit and will not require remeasurement after issuance. The following table presents the quantitative information regarding market assumptions used in the Level 3 valuation of the Public Warrants (refer to Note 8 for more detail):

Class A Ordinary Shares Subject to Possible Redemption Classification

The public shares contain a redemption feature which allows for the redemption of such public shares in connection with the Company’s liquidation, 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 possible redemption outside of permanent deficit as the redemption provisions are not solely within the control of the Company. The Company recognizes changes in redemption value immediately as it occurs 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 amount 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 June 30, 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 consolidated balance sheets. As of June 30, 2026 and December 31, 2025, the Class A ordinary shares subject to possible redemption reflected in the condensed consolidated balance sheets are reconciled in the following table:

Share-Based Compensation

The Company records share-based compensation in accordance with FASB ASC Topic 718, “Compensation-Share Compensation” (“ASC 718”), guidance to account for its share-based compensation. It defines a fair value-based method of accounting for an employee share option or similar equity instrument. The Company recognizes all forms of share-based payments at their fair value on the grant date, which are based on the estimated number of awards that are ultimately expected to vest. Share-based payments are valued using a Black-Scholes option pricing model. Grants of share-based payment awards issued to non-employees for services rendered have been recorded at the fair value of the share-based payment, which is the more readily determinable value. The grants are amortized on a straight-line basis over the requisite service periods, which is generally the vesting period. If an award is granted, but vesting does not occur, any previously recognized compensation cost is reversed in the period related to the termination of service. Share-based compensation expenses are included in costs and operating expenses depending on the nature of the services provided in the unaudited condensed consolidated statements of operations.

Derivative Financial Instruments

The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, “Derivatives and Hedging.” For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then re-valued at each reporting date, with changes in the fair value reported in the unaudited condensed consolidated statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative liabilities are classified in the condensed consolidated balance sheets as current or non-current based on whether or not net cash settlement or conversion of the instrument could be required within 12 months of the condensed consolidated balance sheet date. The underwriters’ over-allotment option is deemed to be a freestanding financial instrument indexed on the contingently redeemable shares and would have been accounted for as a liability pursuant to ASC 480 if not fully exercised at the time of the Initial Public Offering. Because the over-allotment option was fully exercised at the time of the Initial Public Offering, no liability remained outstanding subsequent to the offering date.

Recently Issued Accounting Standards

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

NOTE 3 — INITIAL PUBLIC OFFERING

Pursuant to the Initial Public Offering on January 16, 2025, the Company sold 17,250,000 Public Shares, which includes a full exercise by the underwriters of their over-allotment option at a purchase price of $10.00 per Unit. Each Unit consists of one Class A ordinary share and one-half of one redeemable public warrant (“Public Warrant”). Each whole Public Warrant entitles the holder to purchase one Class A ordinary share at an exercise price of $11.50 per share, subject to adjustment (see Note 6).

NOTE 4 — PRIVATE PLACEMENT

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of an aggregate of 672,875 private placement units (each, a “Private Placement Unit”) at a price of $10.00 per Private Placement Unit, or Non-Managing Investor Private Placement Security (as defined below) generating gross proceeds of $6,728,750, as follows: (i) by and among the Company and each of the underwriters for the purchase by the underwriters of an aggregate of 232,875 Private Placement units for an aggregate purchase price of $2,328,750 and (ii) by and between the Company and the Sponsor for the purchase by the Sponsor of an aggregate of 440,000 Private Placement Units and 570,000 restricted Class A ordinary shares (the “Restricted Private Placement Shares,” the Restricted Private Placement Shares together with the Private Placement Units purchased by the Sponsor, collectively, the “Non-Managing Investor Private Placement Securities”) for an aggregate purchase price of $4,400,000.

Each Private Placement Unit has an offering price of $10.00 and consists of one Class A ordinary share and one-half of one redeemable Public Warrant. Each whole Public Warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share. The proceeds from the sale of the Private Placement Units and the Non-Managing Investor Private Placement Securities were added to the net proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the proceeds from the sale of the Private Placement Units and the Non-Managing Investor Private Placement Securities held in the Trust Account will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law) and the Private Placement Warrants expire worthless.

The Restricted Private Placement Shares are held by the Sponsor and will be transferred to the non-managing investors (or their designees) only upon the consummation of an initial business combination. Other than such permitted transfer, the Restricted Private Placement Shares will be subject to transfer restrictions for 90 days following the initial business combination and will be entitled to registration rights.

The fair value of the Restricted Private Placement Shares is $285,000, or $0.50 per Restricted Private Placement Shares. The fair value of the Restricted Private Placement Shares was determined using Monte Carlo Simulation Model. The Restricted Private Placement Shares have been classified within shareholders’ deficit and will not require remeasurement after issuance. The following table presents the quantitative information regarding market assumptions used in the valuation of the Restricted Private Placement Shares:

Unit value	$	10.02
Volatility		2.9	%

NOTE 5 — RELATED PARTY TRANSACTIONS

Founder Shares

On June 26, 2024, the Sponsor paid $25,000, or approximately $0.003 per share in consideration for 7,665,900 Class B ordinary shares (the “Founder Shares”) issued to the Sponsor. On December 6, 2024, the Sponsor surrendered 1,915,900 Founder Shares for no consideration. All share and per share amounts have been retroactively restated. The initial shareholders currently hold an aggregate of 5,750,000 Founder Shares.

The Founder Shares included an aggregate of up to 750,000 shares subject to forfeiture by the holders thereof depending on the extent to which the underwriters’ over-allotment option was exercised, so that the number of Founder Shares would have collectively represented 25% of the Company’s issued and outstanding shares upon the completion of the Initial Public Offering (not including the Restricted Private Placement Shares). On January 16, 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 Sponsor has agreed, subject to limited exceptions, not to transfer, assign or sell any of its Founder Shares until the earlier to occur of (A) one year after the completion of a Business Combination; and (B) subsequent to a Business Combination, (x) if the last reported sale 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 a Business Combination, or (y) the date on which the Company completes a liquidation, merger, amalgamation, share exchange, reorganization or other similar transaction 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.

During July and August 2024, the Sponsor transferred 75,000 Founder Shares to three director nominees (25,000 shares each) for an aggregate amount of $225, or approximately $0.003 per share. The sale of the Founder Shares to the Company’s directors and director’s nominees is in the scope of FASB ASC Topic 718, “Compensation-Stock Compensation” (“ASC 718”). Under ASC 718, stock-based compensation associated with equity-classified awards is measured at fair value upon the grant date. The fair value of the 75,000 shares granted to the Company’s director nominees was $36,750 or $0.49 per share. The Founder Shares were granted subject to a performance condition (i.e., named as directors at the occurrence of the Initial Public Offering). Compensation expense related to the Founder Shares is recognized only when the performance condition is probable of occurrence under the applicable accounting literature. Stock-based compensation was recognized upon the consummation of the Initial Public Offering in an amount equal to the number of Founder Shares times the grant date fair value per share (unless subsequently modified) less the amount initially received for the purchase of the Founder Shares.

Promissory Note — Related Party

On June 26, 2024, the Company issued an unsecured promissory note to the Sponsor (as amended on January 6, 2025, the “Promissory Note”), pursuant to which the Company may borrow up to an aggregate principal amount of $500,000. The Promissory Note is non-interest bearing and payable on the earlier of (i) February 1, 2025 (as amended) or (ii) the consummation of the Initial Public Offering. As of January 16, 2025, the Company owed $284,023, which was repaid simultaneously with the closing of the Initial Public Offering. The Company paid the Sponsor a note balance of $285,318 causing an overpayment of $1,295. On January 22, 2025, the Sponsor returned $1,295 to the Company. Borrowings under this note are no longer available. As of June 30, 2026 and December 31, 2025, there were no outstanding under the Promissory Note, respectively.

On July 8, 2025, the Company issued an unsecured promissory note (the “Note”) in the principal amount of up to $1,500,000 to Sponsor which may be drawn down from time to time prior to the Maturity Date (as defined below) upon request by the Company. The Note does not bear interest and the principal balance will be payable on the date on which the Company consummates its Business Combination (the “Maturity Date”). In the event the Company consummates the Business Combination, the Sponsor has the option on the Maturity Date to convert the principal outstanding under the Note into that number of ordinary shares of the post-business combination company (the “New PubCo Shares”). The number of New PubCo Shares to be received by the Sponsor in connection with such optional conversion shall be an amount determined by dividing (x) the sum of the outstanding principal amount (or portion thereof) payable to such Sponsor by (y) $10.00. The Note is subject to customary events of default, the occurrence of certain of which automatically triggers the unpaid principal balance of the Note and all other sums payable with regard to the Note becoming immediately due and payable.

The Company accounts for the Note as a liability under ASC 470. The Company has not elected the fair value option under ASC 825-10. The embedded conversion feature is indexed to the Company’s own stock, meets the fixed-for-fixed criteria, and is not required to be bifurcated under ASC 815-15. Accordingly, the conversion feature qualifies for equity classification under ASC 815-40, provided there are sufficient authorized shares to settle the conversion, and no cash settlement contingencies exist. As a result, the Note is recognized at its principal amount, net of issuance costs, and presented and disclosed in accordance with ASC 470.

As of June 30, 2026 and December 31, 2025, there was $800,000 and $250,000 outstanding under the Note, respectively.

Consulting Services

The Chief Executive Officer and the Chief Financial Officer entered into agreements with the Company, commencing on January 16, 2025 through the closing of the Company’s Business Combination, to pay each officer an aggregate of $20,833 per month, subject to availability of sufficient funds from working capital held outside the Trust Account. For the three and six months ended June 30, 2026, the Company incurred approximately $125,000 and $250,000, respectively, in fees for these services. For the three and six months ended June 30, 2025, the Company incurred approximately $125,000 and $233,000 in consulting fees to the officers, respectively. As of June 30, 2026 and December 31, 2025, approximately $21,000 and $31,000 in unpaid consulting fees has been accrued and recorded under accrued expenses in the accompanying condensed consolidated balance sheets, respectively.

Related Party Loans

In order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, any of their respective affiliates or certain of the Company’s directors and officers may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a Business Combination, the Company would repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination does not close, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans, but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. The Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender’s discretion, up to $1,500,000 of such Working Capital Loans may be convertible into units at a price of $10.00 per unit. The units would be identical to the Private Placement Units. As of June 30, 2026 and December 31, 2025, there are no Working Capital Loans outstanding.

NOTE 6 — COMMITMENTS AND CONTINGENCIES

Registration Rights

The holders of the (i) Founder Shares, (ii) Restricted Private Placement Shares, (iii) Private Placement Units, issued in a private placement simultaneously with the closing of the Initial Public Offering, private placement shares, private placement warrants and the Class A ordinary shares underlying such private placement warrants and (iv) private placement units that may be issued upon conversion of working capital loans are entitled to registration rights pursuant to a registration rights agreement signed on the effective date of the Initial Public Offering requiring the Company to register such securities for resale (in the case of the Founder Shares, only after conversion to Class A ordinary shares). The holders of these securities will be entitled to make up to three demands, excluding short form registration demands, that the Company register such securities. In addition, the holders have certain piggyback registration rights with respect to registration statements filed subsequent to the completion of a Business Combination and rights to require the Company to register for resale such securities pursuant to Rule 415 under the Securities Act. However, the registration rights agreement provides that the Company will not be required to effect or permit any registration or cause any registration statement to become effective until termination of the applicable lock-up period. The registration rights agreement does not contain liquidating damages or other cash settlement provisions resulting from delays in registering the Company’s securities. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting Agreement

The Company has granted the underwriters a 45-day option to purchase up to 2,250,000 additional Units to cover over-allotments at the Initial Public Offering price, less the underwriting commissions. As of January 16, 2025, simultaneously with the closing of the Initial Public Offering, the underwriters elected to fully exercise the over-allotment option to purchase the additional 2,250,000 Units at a price of $10.00 per Unit

The underwriters were entitled to (1) an underwriting discount of $0.20 per Unit, or $3,450,000 in the aggregate, of which (i) $0.065 per unit was paid to the underwriters in cash at the closing of the Initial Public Offering and (ii) $0.135 per Unit was used by the underwriters to purchase Private Placement Units, and (2) a deferred fee of $0.40 per Unit, or $6,900,000. The deferred fee will become payable to the underwriters from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement and will be based on the amount of funds remaining in the Trust Account after shareholder redemptions of public shares in connection with the consummation of a Business Combination.

Warrants — As of June 30, 2026 and December 31, 2025, there were 8,961,438 warrants outstanding, including 8,625,000 Public Warrants and 336,438 Private Placement Warrants. Public Warrants may only be exercised for a whole number of shares. No fractional shares will be issued upon exercise of the Public Warrants. The Public Warrants will become exercisable on the later of (a) 30 days after the completion of a Business Combination and (b) 12 months from the closing of the Initial Public Offering. The Public Warrants will expire seven years from the completion of a Business Combination or earlier upon redemption or liquidation.

The Company will not be obligated to deliver any Class A ordinary shares pursuant to the exercise of a Public Warrant and will have no obligation to settle such Public Warrant exercise unless a registration statement under the Securities Act covering the issuance of the Class A ordinary shares issuable upon exercise of the warrants is then effective and a current prospectus relating thereto is available, subject to the Company satisfying its obligations with respect to registration, or a valid exemption from registration is available. No warrant will be exercisable for cash or on a cashless basis, and the Company will not be obligated to issue any shares to holders seeking to exercise their warrants, unless the issuance of the shares upon such exercise is registered or qualified under the securities laws of the state of the exercising holder, or an exemption is available.

The Company has agreed that as soon as practicable, but in no event later than 15 business days, after the closing of a Business Combination, it will use its commercially reasonable efforts to file with the SEC a registration statement covering the issuance, under the Securities Act, of the Class A ordinary shares issuable upon exercise of the warrants, and the Company will use its commercially reasonable efforts to cause the same to become effective within 60 business days after the closing of a Business Combination and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration of the warrants in accordance with the provisions of the warrant agreement. 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, but 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.

Redemption of Public Warrants — Once the warrants become exercisable, the Company may redeem the outstanding Public Warrants:

●

in whole and not in part;

●

at a price of $0.01 per Public Warrant;

●

upon not less than 30 days’ prior written notice of redemption to each warrant holder; and

●

if, and only if, the closing price of the Class A ordinary shares equals or exceeds $18.00 per share (as adjusted for share subdivisions, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to warrant holders.

The Company will not redeem the warrants for cash unless a registration statement under the Securities Act covering the issuance of the shares of Class A ordinary shares issuable upon exercise of the warrants is then effective and a current prospectus relating to those Class A ordinary shares is available throughout the 30-day redemption period or the Company has elected to require the exercise of the public warrants on a cashless basis. If and when the warrants become redeemable by the Company, the Company may exercise its redemption right even if the Company is unable to register or qualify the underlying securities for sale under all applicable state securities laws.

If the Company calls the warrants for redemption as described in this paragraph, its management will have the option to require any holder that wishes to exercise his, her or its warrant following the notice of redemption to do so on a cashless basis. In the case of such a cashless exercise, each holder would pay the exercise price by surrendering the Public 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” less the exercise price of the warrants by (y) the fair market value. The “fair market value” as used in the preceding sentence shall mean the volume weighted average price of the Class A ordinary shares for the 10 trading days ending on the trading day prior to the date on which the notice of redemption is sent to the holders of the public warrants. If its management takes advantage of this option, the notice of redemption will contain the information necessary to calculate the number of shares of Class A ordinary shares to be received upon exercise of the warrants, including the “fair market value” in such case.

PLUM ACQUISITION CORP. IV
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
JUNE 30, 2026
(UNAUDITED)

The Company has established the $18.00 per share (as adjusted) redemption criterion discussed above to prevent a redemption call unless there is at the time of the call a significant premium to the public warrant exercise price. If the foregoing conditions are satisfied and the Company issues a notice of redemption of the Public Warrants, each Public Warrant holder will be entitled to exercise his, her or its Public Warrant prior to the scheduled redemption date. However, the price of the Class A ordinary shares may fall below the $18.00 redemption trigger price as well as the $11.50 Public Warrant exercise price after the redemption notice is issued.

In addition, if (x) the Company issues additional ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of its Initial Business Combination at an issue price or effective issue price of less than $9.20 per ordinary share (with such issue price or effective issue price to be determined in good faith by its board of directors and, in the case of any such issuance to either of the Sponsor or its affiliates, without taking into account any Founder Shares held by the Sponsor or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of its Initial Business Combination on the date of the completion of its Initial Business Combination (net of redemptions), and (z) the volume weighted average trading price of Class A ordinary shares during the 20 trading day period starting on the trading day prior to the day on which the Company consummates its initial business combination (such price, the “Market Value”) is below $9.20 per share, the exercise price of the public warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, the $18.00 per share redemption trigger price will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price.

The Private Placement Warrants are identical to the Public Warrants underlying the Units being sold in the Initial Public Offering, except that the Private Placement Warrants and the Class A ordinary shares issuable upon the exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be exercisable on a cashless basis and be non-redeemable.

NOTE 7 — SHAREHOLDERS’ DEFICIT

Preference Shares — The Company is authorized to issue 1,000,000 preference shares with a par value of $0.0001 per share, with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s board of directors. As of June 30, 2026 and December 31, 2025, there were no preference shares issued or outstanding.

Class A Ordinary Shares — The Company is authorized to issue 200,000,000 Class A ordinary shares, with a par value of $0.0001 per share. Holders of Class A ordinary shares are entitled to one vote for each share.

Only holders of Class B ordinary shares will have the right to vote on the election of directors prior to the Business Combination. Holders of Class A ordinary shares and holders of Class B ordinary shares will vote together as a single class on all other matters submitted to a vote of the Company’s shareholders except as otherwise required by law.

The Class B ordinary shares will automatically convert into Class A ordinary shares at the time of a Business Combination or earlier at the option of the holder, on a one-for-one basis, subject to adjustment.

On July 9, 2026, the Sponsor and the Company’s independent directors voluntarily converted an aggregate of 5,749,999 Class B Ordinary Shares into 5,749,999 Class A Ordinary Shares, as permitted by the Company’s Articles. The Class B Ordinary Shares that converted into Class A Ordinary Shares will not be entitled to receive funds from the Trust Account through redemptions or otherwise and will remain subject to the existing transfer restrictions. Following the conversions and redemptions, there are a total of 10,702,490 Class A Ordinary Shares outstanding and one Class B Ordinary Share outstanding, which Class B Ordinary Share is held by the Sponsor.

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 and liabilities that are measured at fair value on a recurring basis as of June 30, 2026 and indicates the fair value hierarchy of the valuation techniques that the Company utilized to determine such fair value:

	Maturity Date:	Level		June 30, 2026		December 31, 2025
Asset:
Investments held in Trust Account – U.S. Treasury Securities	July 16, 2026		1	$	184,416,026	$	181,285,220

Upon maturity, the proceeds were subsequently invested in accordance with the investment provisions set forth in the Trust Account Agreement.

NOTE 9 — SEGMENT REPORTING

ASC Topic 280, “Segment Reporting,” establishes standards for companies to report in their unaudited condensed consolidated financial statements information about operating segments, products, services, geographic areas, and major customers. Operating segments are defined as components of an enterprise that engage in business activities from which it may recognize revenues and incur expenses, and for which separate financial information is available that is regularly evaluated by the Company’s chief operating decision maker (“CODM”), or group, in deciding how to allocate resources and assess performance.

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

PLUM ACQUISITION CORP. IV
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

The CODM assesses performance for the single segment and decides how to allocate resources based on net income or loss that also is reported on the unaudited condensed consolidated statements of operations as net income or loss. The measure of segment assets is reported on the condensed consolidated balance sheets as total assets. When evaluating the Company’s performance and making key decisions regarding resource allocation, the CODM reviews the below key metric included in net income or loss:

	For the Three Months Ended June 30, 2026		For the Three Months Ended June 30, 2025		For the Six Months Ended June 30, 2026		For the Six Months Ended June 30, 2025
General and administrative expenses	$	1,105,308	$	237,782	$	1,358,023	$	544,127
Interest earned on investments held in Trust Account	$	1,680,837	$	1,867,009	$	3,130,806	$	3,355,409

	June 30, 2026		December 31, 2025
Cash	$	288,518	$	296,249
Investments held in Trust Account	$	184,416,026	$	181,285,220

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 expenses to manage, maintain and enforce all contractual agreements to ensure costs are aligned with all agreements and budget. General and administrative expenses, as reported on the unaudited condensed consolidated statements of operations, are the significant segment expenses provided to the CODM on a regular basis.

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

NOTE 10 — SUBSEQUENT EVENTS

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

On July 10, 2026, the Company held the Shareholder Meeting to amend the Company’s Articles to extend the date by which the Company has to consummate a business combination from July 16, 2026 to January 16, 2027 and to allow Plum IV, without another shareholder vote, to elect to extend the Termination Date to consummate a Business Combination on a monthly basis for up to six times by an additional one month each time after the Articles Extension Date, by resolution of the Company’s board of directors if requested by the Sponsor and upon five days’ advance notice prior to the applicable Termination Date, until July 16, 2027, or a total of up to twelve months after the Termination Date, unless the closing of a business combination shall have occurred prior to such date.

On March 8, 2026, we entered into a business combination agreement (the “Business Combination Agreement”) by and among us, Plum IV Merger Sub, Inc., a Delaware corporation and our direct wholly owned subsidiary (“Merger Sub”) and our direct wholly owned subsidiary, and Controlled Thermal Resources Holdings Inc., a Delaware corporation (“CTR”), pursuant to which, among other things and subject to the terms and conditions contained therein, Merger Sub will merge with and into CTR (the “Merger”), with CTR continuing as the surviving company. The combined company’s business is expected to continue to operate through CTR. The proposed Merger is expected to be consummated after receipt of the required approvals by our shareholders and CTR’s stockholders and the satisfaction or waiver of certain other customary conditions.

On May 15, 2026, we and Merger Sub entered into an amendment to the Business Combination Agreement (the “First BCA Amendment”), which amends the Business Combination Agreement to, among other things, (i) extend the date by which we are required to deliver financial statements and pro forma financial information of the Company required to be included in the proxy statement/prospectus of the Registration Statement on Form S-4 from May 15, 2026 to June 15, 2026 and June 30, 2026, respectively; (ii) extend the date by which we and Merger Sub are required to make any filings or applications required under antitrust laws with respect to the Business Combination Agreement from April 17, 2026 to July 31, 2026; and (iii) extend the dates by which we are required to deliver certain material consents from May 7, 2026 to the dates listed on Schedule 8.01(m) to the Business Combination Agreement.

On July 6, 2026, we and Merger Sub entered into a second amendment to the Business Combination Agreement (the “Second BCA Amendment” and the Business Combination Agreement, as amended by the First BCA Amendment and the Second BCA Amendment, the “Amended BCA”), which amends the Business Combination Agreement to, among other things, (i) reduce the aggregate number of potential earnout shares issuable to our shareholders following the closing from 100,000,000 to 70,000,000, with each of the eight earnout tranches reduced proportionally from 12,500,000 to 8,750,000 shares; (ii) extend the date by which the parties are required to make any filings or applications required under antitrust laws with respect to the transactions contemplated by the Amended BCA from July 31, 2026 to September 30, 2026; (iii) increase the maximum number of shares issuable to our sponsor as reimbursement for founder shares issued to our shareholders, or issuable to our shareholders, who agree not to redeem their shares from 2,000,000 to 3,000,000; (iv) extend the date by which the closing must occur from December 31, 2026 to April 30, 2027; (v) reduce the valuation used to calculate the merger consideration from $4,500,000,000 to $3,150,000,000; and (vi) extend the deadlines by which we are required to deliver certain material consents to the dates listed on Schedule 8.01(m) to the Amended BCA.

For more information about the Business Combination Agreement, the Amended BCA and the Business Combination, see Note 1- “Proposed Business Combination”.

Transaction Support Agreement

Simultaneously with the execution and delivery of the Business Combination Agreement, we and certain stockholders of CTR (collectively, the “Supporting CTR Stockholders”), who collectively have the right to cast at least 60% of the votes entitled to be cast at a special meeting of CTR’s stockholders entered into a transaction support agreement (the “Transaction Support Agreement”), pursuant to which the Supporting CTR Stockholders have agreed, among other things, to vote all of their shares of CTR’s common stock in favor of adopting and approving the Business Combination Agreement and the Business Combination.

Registration Rights Agreement

In connection with the Business Combination, simultaneously with the closing of the Business Combination (the “Closing”), we and certain holders will enter into an (the “Amended and Restated Registration Rights Agreement”) Amended and Restated Registration Rights Agreement that amends and restates the Registration Rights Agreement, dated January 14, 2025, by and among us, our sponsor and certain other security holders named therein, pursuant to which, among other things, (i) we will agree to file, as soon as practicable (and in any event within thirty (30) calendar days) following the closing date, a registration statement covering the resale of certain equity securities held by the sponsor and such other securityholders parties thereto; and (ii) such holders of registrable securities will be granted certain takedown, demand, block trade and piggyback registration rights with respect to their registrable securities, in each case, on the terms and subject to the conditions set forth in the Amended and Restated Registration Rights Agreement.

Lock-Up Agreement

In connection with the Business Combination, simultaneously with the Closing, we, our sponsor and certain stockholders of CTR (such holders, collectively, the “Lock-Up Parties”) will enter into a Lock-Up Agreement (the “Lock-Up Agreement”). The Lock-Up Agreement will provide that, during the applicable Lock-Up Period (as defined in the Lock-Up Agreement), subject to certain exceptions, the Lock-Up Parties will not, with respect to the Lock-Up Securities (as defined in the Lock-Up Agreement), (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent position or liquidation with respect to or decrease a call equivalent position, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any security, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (iii) publicly announce the intention to effect any transaction specified in clause (i) or (ii).

July 2025 Promissory Note

On July 8, 2025, we issued an unsecured promissory note in the principal amount of up to $1,500,000 to the sponsor which may be drawn down from time to time prior to the Maturity Date (as defined below) upon our request. The Note (as defined below) does not bear interest and the principal balance will be payable on the date on which we consummate our initial business combination. In the event we consummate the business combination, the sponsor has the option on the Maturity Date to convert the principal outstanding under the Note into that number of ordinary shares of the post-business combination company. The number of New PubCo Shares (as defined below) to be received by the sponsor in connection with such optional conversion will be an amount determined by dividing (x) the sum of the outstanding principal amount (or portion thereof) payable to the sponsor by (y) $10.00. The Note is subject to customary events of default, the occurrence of certain of which automatically triggers the unpaid principal balance of the Note and all other sums payable with regard to the Note becoming immediately due and payable.

Shareholder Meeting

On July 10, 2026, we held an extraordinary general meeting of our shareholders (the “Shareholder Meeting”) to amend our amended and restated memorandum and articles of association (the “Articles”) to extend the date (the “Termination Date”) by which we have to consummate a business combination (the “Articles Extension”) from July 16, 2026 to January 16, 2027 (the “Articles Extension Date”) and to allow us, without another shareholder vote, to elect to extend the Termination Date to consummate a Business Combination on a monthly basis for up to six times by an additional one month each time after the Articles Extension Date, by resolution of the Company’s board of directors if requested by the Sponsor and upon five days’ advance notice prior to the applicable Termination Date, until July 16, 2027, or a total of up to twelve months after the Termination Date, unless the closing of a business combination shall have occurred prior to such date (the “Extension Amendment Proposal”).

In connection with the vote to approve the Extension Amendment Proposal, the holders of 13,540,384 public shares properly exercised their right to redeem their shares for cash at a redemption price of approximately $10.71 per share, for an aggregate redemption amount of approximately $145 million, leaving approximately $39.7 million in the trust account.

Results of Operations

We have neither engaged in any operations nor generated any operating revenues to date. Our only activities for the period from June 10, 2024 (inception) through June 30, 2026 were organizational activities and those necessary to prepare for the initial public offering, described below and, after our initial public offering, identifying a target company for a business combination. We do not expect to generate any operating revenues until after the completion of our initial business combination. We expect to generate non-operating income in the form of interest income on marketable securities held after the initial public offering. We expect that we will incur increased expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), as well as for due diligence expenses in connection with searching for, and completing, a business combination.

For the three months ended June 30, 2026, we had a net income of $577,124, which consists of interest earned on investments held in Trust Account of $1,680,837 and interest earned on operating account of $1,595, offset by general and administrative expenses of $1,105,308.

For the three months ended June 30, 2025, we had a net income of $1,629,227, which consists of interest earned on investments held in Trust Account of $1,867,009 offset by general and administrative expenses of $237,782.

For the six months ended June 30, 2026, we had a net income of $1,776,258, which consists of interest earned on investments held in Trust Account of $3,130,806 and interest earned on operating account of $3,475, offset by general and administrative expenses of $1,358,023.

For the six months ended June 30, 2025, we had a net income of $2,811,282, which consists of interest earned on investments held in Trust Account of $3,355,409 offset by general and administrative expenses of $544,127.

Liquidity and Capital Resources

As of June 30, 2026, we had cash of $288,518. Until the consummation of the initial public offering, our only source of liquidity was an initial purchase of ordinary shares by the sponsor and loans from our sponsor.

On January 16, 2025, we consummated the initial public offering of 17,250,000 units, at a price of $10.00 per unit, which included the full exercise by the underwriters of their over-allotment option in the amount of 2,250,000 units, generating gross proceeds of $172,500,000. Simultaneously with the closing of the initial public offering, we consummated the sale of an aggregate of 672,875 private placement units to the sponsor at a price of $10.00 per private placement unit generating gross proceeds of $6,728,750.

Following the initial public offering, on January 16, 2025, the full exercise of the over-allotment option, and the sale of the private placement units, a total of $174,225,000 was placed in the trust account, and we had $971,550 of cash held outside of the trust account, after payment of costs related to the initial public offering, and available for working capital purposes. We incurred $10,932,289 in transaction costs, including $3,450,000 of underwriting fees, $6,900,000 of deferred underwriting fees and $582,289 of other offering costs.

For the six months ended June 30, 2026, cash used in operating activities was $482,731. Net income of $1,776,258 was affected by interest earned on investments held in trust account of $3,130,806. Changes in operating assets and liabilities provided $871,817 of cash for operating activities.

For the six months ended June 30, 2025, cash used in operating activities was $539,932. Net income of $2,811,282 was affected by interest earned on investments held in trust account of $3,355,409, compensation expense of $36,750 and payment of operation costs through promissory note of $8,550. Changes in operating assets and liabilities used $41,105 of cash for operating activities.

As of June 30, 2026, we had investments held in the trust account of $184,416,026. We intend to use substantially all of the funds held in the trust account, including any amounts representing interest earned on the trust account, which interest shall be net of taxes payable, to complete our business combination. We may withdraw interest from the trust account to pay taxes, if any. To the extent that our share capital or debt is used, in whole or in part, as consideration to complete a 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 June 30, 2026, we had cash of $288,518 for working capital purpose. 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, structure, negotiate and complete a business combination.

In order to fund working capital deficiencies or finance transaction costs in connection with a business combination, our sponsor or an affiliate of our sponsor or certain of our officers and directors may, but are not obligated to, loan us funds as may be required. If we complete a business combination, we may repay such loaned amounts out of the proceeds of the trust account released to us. 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 loans may be convertible into units, at a price of $10.00 per unit, at the option of the lender. The units would be identical to the private placement units.

On July 8, 2025, we issued an unsecured promissory note (the “Note”) in the principal amount of up to $1,500,000 to the sponsor which may be drawn down from time to time prior to the Maturity Date upon our request. The Note does not bear interest and the principal balance will be payable on the date on which we consummate our initial business combination (the “Maturity Date”). In the event we consummate the business combination, the sponsor has the option on the Maturity Date to convert the principal outstanding under the Note into that number of ordinary shares of the post-business combination company (the “New PubCo Shares”). The number of New PubCo Shares to be received by the sponsor in connection with such optional conversion will be an amount determined by dividing (x) the sum of the outstanding principal amount (or portion thereof) payable to the sponsor by (y) $10.00. The Note is subject to customary events of default, the occurrence of certain of which automatically triggers the unpaid principal balance of the Note and all other sums payable with regard to the Note becoming immediately due and payable.

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 initial 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 completion of our business combination, in which case we may issue additional securities or incur debt in connection with such business combination.

Going Concern

As of June 30, 2026, we had $288,518 in cash and working capital deficit of $1,421,716. Further, we have incurred and expect to continue to incur significant costs in pursuit of our acquisition plans. There is no assurance that our plans to raise capital will be successful. In connection with our assessment of going concern considerations in accordance with Accounting Standards Codification (“ASC”) Topic 205-40, “Going Concern,” as of June 30, 2026, management has determined that mandatory liquidation, should a business combination not occur, and potential subsequent dissolution and the liquidity issue raise substantial doubt about our ability to continue as a going concern for one year from the date the unaudited condensed consolidated financial statements are issued.

No adjustments have been made to the carrying amounts of assets or liabilities should we be required to liquidate after January 16, 2027, or such earlier liquidation date as our board of directors may approve to complete our initial business combination. We cannot assure that our plans to raise capital or to consummate an initial business combination will be successful.

Off-Balance Sheet Arrangements

We have no obligations, assets or liabilities, which would be considered off-balance sheet arrangements as of June 30, 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, excluding the promissory note – related party, capital lease obligations, operating lease obligations or long-term liabilities, other than an agreement to pay each officer an aggregate of $20,833 per month, subject to availability of sufficient funds from working capital held outside the trust account. We began incurring these fees on January 16, 2025, and will continue to incur these fees monthly until the earlier of the completion of the business combination and our liquidation.

The underwriters were entitled to (1) an underwriting discount of $0.20 per unit, or $3,450,000 in the aggregate, of which (i) $0.065 per unit was paid to the underwriters in cash at the closing of the initial public offering and (ii) $0.135 per unit was used by the underwriters to purchase private placement units, and (2) a deferred fee of $0.40 per unit, or $6,900,000. The deferred fee will become payable to the underwriters from the amounts held in the trust account solely in the event that we complete a business combination, subject to the terms of the underwriting agreement and will be based on the amount of funds remaining in the trust account after shareholder redemptions of public shares in connection with the consummation of a business combination.

Critical Accounting Estimates and Policies

The preparation of unaudited condensed consolidated 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 consolidated financial statements, and income and expenses during the periods reported. Actual results could materially differ from those estimates. We have not identified any critical accounting policies.

Recent Accounting Standards

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

Under the supervision and with the participation of our management, including our Certifying Officers, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on the foregoing, our Certifying Officers concluded that our disclosure controls and procedures were effective as of June 30, 2026.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting during the quarterly period ended June 30, 2026 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 Quarterly Report are any of the risks described in the section titled “Risk Factors” contained in our Annual Report on Form 10-K and below. Any of these factors could result in a significant or material adverse effect on our results of operations or financial condition. Additional risk factors not presently known to us or that we currently deem immaterial may also impair our business or results of operations. As of the date of this Quarterly Report, there have been no material changes to the risk factors disclosed in our Annual Report on Form 10-K and below, however, we may disclose changes to such risk factors or disclose additional risk factors from time to time in our future filings with the SEC.

There is substantial doubt about our ability to continue as a going concern.

As of June 30, 2026, we had $288,518 in cash and a working capital deficit of $1,421,716. Further, we have incurred and expect to continue to incur significant costs in pursuit of our acquisition plans. There is no assurance that our plans to raise capital will be successful. Management has determined that our liquidity condition raises substantial doubt about our ability to continue as a going concern. No adjustments have been made to the carrying amounts of assets or liabilities should we be required to liquidate after January 16, 2027, or such earlier liquidation date as our board of directors may approve to complete our initial business combination. We cannot assure that our plans to raise capital or to consummate an initial business combination will be successful.

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

On January 16, 2025, we consummated the initial public offering of 17,250,000 units. The units were sold at an offering price of $10.00 per unit, generating gross proceeds of $172,500,000. Cohen & Company Capital Markets acted as lead book-running manager, Seaport Global Securities acted as joint book runner and Benjamin Securities, Inc. acted as co-manager, of the initial public offering. The securities in the offering were registered under the Securities Act on a registration statement on Form S-1 (File No. 333-281144). The SEC declared the registration statement effective on January 14, 2025.

Simultaneously with the closing of the initial public offering, we consummated the sale of an aggregate of 672,875 private placement units at a price of $10.00 per private placement unit, generating gross proceeds of $6,728,750. Each private placement unit has an offering price of $10.00 and consists of one Class A ordinary share and one-half of one redeemable public warrant. Each whole public warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share. The issuance was made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act.

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.

On January 16, 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.

We paid a total of $10,932,289, consisting of $3,450,000 of cash underwriting fee, $6,900,000 of deferred underwriting fee, and $582,289 of other offering costs.

For a description of the use of the proceeds generated in our initial public offering, see Part I, Item 2 of this Quarterly Report.

Item 3. Defaults Upon Senior Securities

Item 4. Mine Safety Disclosures
