IV NOTES TO CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) NOTE 1 – DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS Plum Acquisition Corp. IV (the “Company”) 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 September 30, 2025, the Company had not commenced any operations. All activity for the period from June 10, 2024 (inception) through September 30, 2025 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. 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. 5 PLUM ACQUISITION CORP. IV NOTES TO CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) 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. 6 PLUM ACQUISITION CORP. IV NOTES TO CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) Risks and Uncertainties The United States and global markets are experiencing volatility and disruption following the geopolitical instability resulting from the ongoing Russia-Ukraine conflict and the Israel-Hamas conflict. In response to the ongoing Russia-Ukraine conflict, the North Atlantic Treaty Organization (“NATO”) deployed additional military forces to eastern Europe, and the United States, the United Kingdom, the European Union and other countries have announced various sanctions and restrictive actions against Russia, Belarus and related individuals and entities, including the removal of certain financial institutions from the Society for Worldwide Interbank Financial Telecommunication payment system. Certain countries, including the United States, have also provided and may continue to provide military aid or other assistance to Ukraine and to Israel, increasing geopolitical tensions among a number of nations. The invasion of Ukraine by Russia and the Israel-Hamas conflict and the resulting measures that have been taken, and could be taken in the future, by NATO, the United States, the United Kingdom, the European Union, Israel and its neighboring states and other countries have created global security concerns that could have a lasting impact on regional and global economies. Although the length and impact of the ongoing conflicts are highly unpredictable, they could lead to market disruptions, including significant volatility in commodity prices, credit and capital markets, as well as supply chain interruptions and increased cyberattacks against U.S. companies. Additionally, any resulting sanctions could adversely affect the global economy and financial markets and lead to instability and lack of liquidity in capital markets. Furthermore, there is currently significant uncertainty regarding the future relationship between the United States and various other countries arising from changes that may be implemented by the new presidential administration, including with respect to trade policies, treaties, tariffs, taxes, and other limitations on cross-border operations. Any actions taken by the United States’ federal government that restrict or could impact the economics of trade-including additional tariffs, trade barriers, and other similar measures-could have the potential to disrupt existing supply chains and trigger retaliatory efforts by other countries, including the imposition of tariffs, raising taxation, setting foreign exchange or capital controls, or establishing embargos, sanctions, or other import/export restrictions, thereby negatively impacting the Company’s business, both directly and indirectly. Any of the above-mentioned factors, or any other negative impact on the global economy, capital markets or other geopolitical conditions resulting from the Russian invasion of Ukraine, the Israel-Hamas conflict and subsequent sanctions or related actions, including the imposition of tariffs, could adversely affect the Company’s search for an initial business combination and any target business with which the Company may ultimately consummate an initial business combination. NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 8 of Regulation S-X of the SEC. Certain information or footnote disclosures normally included in unaudited condensed financial statements prepared in accordance with GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, they do not include all the information and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows. In the opinion of management, the accompanying unaudited condensed financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented. The accompanying unaudited condensed financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, as filed with the SEC on March 31, 2025. The interim results for the three and nine months ended September 30, 2025 are not necessarily indicative of the results to be expected for the year ending December 31, 2025 or for any future periods. Liquidity and Going Concern As of September 30, 2025, the Company had $ 469,208 in cash and a working capital of $ 138,786 . 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. In connection with the Company’s assessment of going concern considerations in accordance with Accounting Standards Codification (“ASC”) Topic 205-40, “Going Concern,” as of September 30, 2025, management has determined that mandatory liquidation, should a Business Combination not occur, and potential subsequent dissolution and the liquidity issue raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date the 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. 7 PLUM ACQUISITION CORP. IV NOTES TO CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) 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 financial statement 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 condensed financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed financial statements 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 condensed financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could 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 $ 469,208 and $ 3,864 in cash as of September 30, 2025 and December 31, 2024, respectively. The Company had no cash equivalents as of September 30, 2025 and December 31, 2024. Investments Held in Trust Account As of September 30, 2025 and December 31, 2024, the investments held in the Trust Account, amounting to $ 179,493,580 and $0 , were held in U.S. government treasury bills, respectively. 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 Units 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 financial statement 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. 8 PLUM ACQUISITION CORP. IV NOTES TO CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) ASC 740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statement and prescribes a recognition threshold and measurement process for financial statement 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 September 30, 2025 and December 31, 2024. 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 (Loss) per Ordinary Share Net income (loss) per ordinary share is computed by dividing net income (loss) 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). At September 30, 2025 and December 31, 2024, 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 (loss) per ordinary share is the same as basic income (loss) per ordinary share for the period presented. The following table reflects the calculation of basic and diluted net income (loss) per ordinary share (in dollars, except per share amounts): For the Three Months Ended September 30, For the Nine Months Ended September 30, For the Period from June 10, 2024 (Inception) Through September 30, 2025 2024 2025 2024 Class A Class B Class A Class B Class A Class B Class A Class B Basic net income (loss) per share of common stock: Numerator: Allocation of net income (loss) $ 1,281,262 $ 398,383 $   — $ ( 44,788 ) $ 3,385,007 $ 1,105,920 $ — $ ( 73,051 ) Denominator: Weighted-average shares outstanding 18,492,875 5,750,000 — 5,000,000 17,473,047 5,708,640 — 5,000,000 Basic net income (loss) per ordinary share $ 0.07 $ 0.07 $ — $ ( 0.01 ) $ 0.19 $ 0.19 $ — $ ( 0.01 ) For the Three Months Ended September 30, For the Nine Months Ended September 30, For the Period from June 10, 2024 (Inception) Through September 30, 2025 2024 2025 2024 Class A Class B Class A Class B Class A Class B Class A Class B Diluted net income (loss) per share of common stock: Numerator: Allocation of net income (loss) $ 1,281,262 $ 398,383 $ — $ ( 44,788 ) $ 3,378,979 $ 1,111,948 $ — $ ( 73,051 ) Denominator: Weighted-average shares outstanding 18,492,875 5,750,000 — 5,000,000 17,473,047 5,750,000 — 5,000,000 Diluted net income (loss) per ordinary share $ 0.07 $ 0.07 $ — $ ( 0.01 ) $ 0.19 $ 0.19 $ — $ ( 0.01 ) 9 PLUM ACQUISITION CORP. IV NOTES TO CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) 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 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. The fair value of the Public Warrants was $ 603,750 , or $ 0.07 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 valuation of the Public Warrants: January 16, 2025 Underlying stock price $ 9.98 Exercise price $ 11.50 Remaining term (years) 6.74 Annual volatility 2.9 % Annual risk-free rate 4.39 % Pre-adjusted value per share $ 1.43 Market adjustment 5.0 % 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 September 30, 2025, Class A ordinary shares subject to possible redemption are presented at redemption value as temporary equity, outside of the shareholders’ deficit section of the Company’s condensed balance sheets. As of September 30, 2025, the Class A ordinary shares subject to possible redemption reflected in the condensed balance sheet are reconciled in the following table: Gross proceeds $ 172,500,000 Less: Proceeds allocated to Public Warrants ( 603,750 ) Class A ordinary shares issuance costs ( 10,872,242 ) Plus: Remeasurement of carrying value to redemption value 14,689,392 Class A ordinary shares subject to possible redemption, March 31, 2025 175,713,400 Plus: Remeasurement of carrying value to redemption value 1,867,009 Class A ordinary shares subject to possible redemption, June 30, 2025 177,580,409 Plus: Remeasurement of carrying value to redemption value 1,913,171 Class A ordinary shares subject to possible redemption, September 30, 2025 $ 179,493,580 10 PLUM ACQUISITION CORP. IV NOTES TO CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) 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 condensed 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 condensed 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 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 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. 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 condensed 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). 11 PLUM ACQUISITION CORP. IV NOTES TO CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) 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: January 16, 2025 Unit value $ 10.02 Volatility 2.9 % Risk free rate 4.39 % Public warrant value $ 0.04 Implied stock value $ 9.98 Market adjustment 5.0 % 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. 12 PLUM ACQUISITION CORP. IV NOTES TO CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) 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 Founders 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. 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. Concurrently with the issuance of the Note, the Company drew an initial amount of $ 250,000 . Due to Officer As of September 30, 2025 and December 31, 2024, the Company owes an officer of the Company $0 and $ 12,374 for travel related expenses, 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. During the three and nine months ended September 30, 2025, the Company incurred approximately $ 125,000 and $ 354,000 in consulting fees to the officers, respectively. As of September 30, 2025, approximately $ 21,000 in unpaid consulting fees has been accrued and recorded under accrued expenses in the accompanying balance sheet. 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 September 30, 2025 and December 31, 2024, there are no Working Capital Loans outstanding. 13 PLUM ACQUISITION CORP. IV NOTES TO CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) 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 September 30, 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. 14 PLUM ACQUISITION CORP. IV NOTES TO CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) 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. 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. 15 PLUM ACQUISITION CORP.

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. 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 September 30, 2025 and indicates the fair value hierarchy of the valuation techniques that the Company utilized to determine such fair value: Level September 30, 2025 Asset: Maturity Date: Investments held in Trust Account – U.S. Treasury Securities October 16, 2025 1 $ 179,493,580 16 PLUM ACQUISITION CORP. IV NOTES TO CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) NOTE 9 — SEGMENT REPORTING ASC Topic 280, “Segment Reporting,” establishes standards for companies to report in their financial statement information about operating segments, products, services, geographic areas, and major customers. Operating segments are defined as components of an enterprise 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. 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 condensed statements of operations as net income or loss. The measure of segment assets is reported on the condensed balance sheets as total assets. When evaluating the Company’s performance and making key decisions regarding resource allocation, the CODM reviews the below key metric included in net income or loss: For the Three Months Ended September 30, 2025 For the Three Months Ended September 30, 2024 For the Nine Months Ended September 30, 2025 For the Period from June 10, 2024 (Inception) Through September 30, 2024 General and administrative expenses $ 236,000 $ 44,788 $ 780,127 $ 73,051 Interest earned on marketable securities held in Trust Account 1,913,171 — 5,268,580 — As of September 30, 2025 As of December 31, 2024 Cash $ 469,208 $ 3,864 Investments held in Trust Account 179,493,580 — 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 condensed 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 condensed 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 balance sheet date up to the date that the unaudited condensed financial statements were issued. Based upon this review, the Company did not identify any subsequent events that would have required adjustment or disclosure in the condensed financial statements. 17 Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations References in this Quarterly Report on Form 10-Q (the “Quarterly Report”) to “we,” “us” or the “Company” refer to Plum Acquisition Corp. IV. References to our “management” or our “management team” refer to our officers and directors, and references to the “sponsor” refer to Plum Partners IV, LLC. The following discussion and analysis of the Company’s financial condition and results of operations should be read in conjunction with the financial statements and the notes thereto contained elsewhere in this Quarterly Report. Certain information contained in the discussion and analysis set forth below includes forward-looking statements that involve risks and uncertainties. Special Note Regarding Forward-Looking Statements This Quarterly Report includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) that are not historical facts and involve risks and uncertainties that could cause actual results to differ materially from those expected and projected. All statements, other than statements of historical fact included in this Quarterly Report including, without limitation, statements in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations” regarding the completion of an initial business combination, the Company’s financial position, business strategy and the plans and objectives of management for future operations, are forward-looking statements. Words such as “expect,” “believe,” “anticipate,” “intend,” “estimate,” “seek” and variations and similar words and expressions are intended to identify such forward-looking statements. Such forward-looking statements relate to future events or future performance, but reflect management’s current beliefs, based on information currently available. A number of factors could cause actual events, performance or results to differ materially from the events, performance and results discussed in the forward-looking statements. For information identifying important factors that could cause actual results to differ materially from those anticipated in the forward-looking statements, please refer to the Risk Factors section of the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2024 (the “Annual Report on Form 10-K”) filed with the U.S. Securities and Exchange Commission (the “SEC”), on March 31, 2025. The Company’s securities filings can be accessed on the EDGAR section of the SEC’s website at www.sec.gov. Except as expressly required by applicable securities law, the Company disclaims any intention or obligation to update or revise any forward-looking statements whether as a result of new information, future events or otherwise. Overview We are a blank check company incorporated in the Cayman Islands on June 10, 2024, formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or other similar business combination with one or more businesses. We intend to effectuate our business combination using cash derived from the proceeds of the initial public offering and the sale of the private placement unit, our shares, debt or a combination of cash, shares and debt. We expect to continue to incur significant costs in the pursuit of our acquisition plans. We cannot assure you that our plans to complete a business combination will be successful. Results of Operations We have neither engaged in any operations nor generated any operating revenues to date. Our only activities from inception through September 30, 2025 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 September 30, 2025, we had a net income of $1,679,645, which consists of interest earned on investments held in Trust Account of $1,913,171 and interest earned on operating account of $2,474, offset by general and administrative expenses of $236,000. For the nine months ended September 30, 2025, we had a net income of $4,490,927, which consists of interest earned on investments held in Trust Account of $5,268,580 and interest earned on operating account of $2,474, offset by general and administrative expenses of $780,127. For the three months ended September 30, 2024, we had a net loss of $44,788, which consists of formation and operational costs. For the period from June 10, 2024 (inception) through September 30, 2024, we had a net loss of $73,051, which consists of formation and operational costs. 18 Liquidity and Capital Resources As of September 30, 2025, we had cash of $469,208. 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 nine months ended September 30, 2025, cash used in operating activities was $696,547. Net income of $4,490,927 was affected by interest earned on investments held in trust account of $5,268,580, compensation expense of $36,750 and payment of operation costs through promissory note of $8,550. Changes in operating assets and liabilities provided $35,806 of cash for operating activities. For the period from June 10, 2024 (inception) through September 30, 2024, cash used in operating activities was $15,438 . Net loss of $73,051 was affected by payment of operation costs through promissory note of $20,820. Changes in operating assets and liabilities used $36,793 of cash for operating activities. As of September 30, 2025, we had investments held in the trust account of $179,493,580. 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 September 30, 2025, we had cash of $469,208 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 (as defined below) 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. 19 Going Concern As of September 30, 2025, we had $469,208 in cash and a working capital of $138,786 . 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 September 30, 2025, management has determined that mandatory liquidation, should a Business Combination not occur, and potential subsequent dissolution and the liquidity issue raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date the financial statements are issued. No adjustments have been made to the carrying amounts of assets or liabilities should we be required to liquidate after July 16, 2026, 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 September 30, 2025. 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 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 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 financial statements. 20 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 the end of the quarterly period ended September 30, 2025. Changes in Internal Control over Financial Reporting There was no change in our internal control over financial reporting during the quarterly period ended September 30, 2025 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. 21 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 September 30, 2025, we had $469,208 in cash and a working capital of $138,786. 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 July 16, 2026, 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. 22 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 None. Item 4. Mine Safety Disclosures Not applicable. Item 5. Other Information Trading Arrangements During the quarterly period ended September 30, 2025, none of our directors or officers (as defined in Rule 16a-1(f) promulgated under the Exchange Act) adopted or terminated any “Rule 10b5-1 trading arrangement” or any “non-Rule 10b5-1 trading arrangement,” as each term is defined in Item 408 of Regulation S-K. Additional Information None. 23 Item 6. Exhibits The following exhibits are filed as part of, or incorporated by reference into, this Report.
