NOTES TO CONDENSED FINANCIAL STATEMENTS JUNE 30, 2026 (Unaudited) ​ NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS Idea Acquisition Corp. (the “Company”) is a blank check company incorporated in the Cayman Islands on September 18, 2025. The Company was formed for the purpose of effecting a merger, amalgamation share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (a “Business Combination”). The Company may pursue an initial Business Combination in any business or industry, but expects to target opportunities and companies operating in the software vertical that leverages large language models or other artificial intelligence tools. 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 September 18, 2025 (inception) through June 30, 2026 relates to the Company’s formation, the initial public offering (“Initial Public Offering” or “IPO”), which is described below, and subsequent to the Initial Public Offering, identifying a target company for a Business Combination. The Company will not generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company generates 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 February 10, 2026. On February 12, 2026, the Company consummated the Initial Public Offering of 35,000,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units offered, the “Public Shares”) at $ 10.00 per Unit, generating gross proceeds of $ 350,000,000 , which is discussed in Note 3. Each Unit consists of one Class A ordinary share and one -third of one redeemable warrant (each, a “Public Warrant”). Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of an aggregate of 6,000,000 warrants (the “Private Placement Warrants” and together with the Public Warrants, the “Warrants”), at a price of $ 1.50 per Private Placement Warrant, in a private placement to Idea Tender LLC (the “Sponsor”) and Cantor Fitzgerald & Co. (“Cantor”), the representative of the underwriters, and Odeon Capital Group, LLC (“Odeon” and together with the Representative, the “Underwriters”), generating gross proceeds of $ 9,000,000 . Of those 6,000,000 Private Placement Warrants, the Sponsor purchased 3,666,667 Private Placement Warrants and the Underwriters purchased an aggregate of 2,333,333 Private Placement Warrants. Transaction costs amounted to $ 21,662,847 , consisting of $ 7,000,000 of cash underwriting fee, $ 14,000,000 of deferred underwriting fee, and $ 662,847 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 Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80 % of the net balance in the Trust Account (as defined below) (excluding the amount of deferred underwriting discounts held and taxes payable on the income earned on the Trust Account) at the time of the signing an agreement to enter into a Business Combination. However, the Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50 % or more of the outstanding voting securities of the target company or otherwise acquires a controlling interest in the target company 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. 5 Table of Contents IDEA ACQUISITION CORP. NOTES TO CONDENSED FINANCIAL STATEMENTS JUNE 30, 2026 (Unaudited) Following the closing of the Initial Public Offering, on February 12, 2026 an amount of $ 350,000,000 ($ 10.00 per Unit) from the net proceeds of the sale of the Units, and a portion of the proceeds of the sale of the Private Placement Warrants was placed in the Trust Account (the “Trust Account”) located in the United States, with Continental Stock Transfer & Trust Company acting as trustee. The funds are initially invested only in U.S. government treasury obligations with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act of 1940, which invest only in direct U.S. government treasury obligations and/or held as cash or cash items (including in demand deposit accounts); the holding of these assets in this form is intended to be temporary and for the sole purpose of facilitating the intended Business Combination. To mitigate the risk that might be deemed to be an investment company for purposes of the Investment Company Act, which risk increases the longer that the Company holds investments in the Trust Account, the Company may, at any time (based on management team’s ongoing assessment of all factors related to the potential status under the Investment Company Act), instruct the trustee to liquidate the investments held in the Trust Account and instead to hold the funds in the Trust Account in cash or in an interest bearing demand deposit account at a bank. Except with respect to interest earned on the funds held in the Trust Account that may be released to the Company to pay its taxes, if any, the proceeds from the Initial Public Offering and the sale of the Private Placement Warrants will not be released from the Trust Account until the earliest of (i) the completion of the Company’s initial Business Combination, (ii) the redemption of the Public Shares if the Company is unable to complete the initial Business Combination within 24 months from the closing of the Initial Public Offering or (x) by such earlier liquidation date as the Company’s board of directors may approve (y) such other time period in which the Company must complete an initial Business Combination pursuant to an amendment to its amended and restated memorandum and articles of association (the “Completion Window”), subject to applicable law, or (iii) the redemption of the Public Shares properly submitted in connection with a shareholder vote to amend the Company’s amended and restated memorandum and articles of association to (A) modify the substance or timing of the Company’s obligation to allow redemption in connection with the initial Business Combination or to redeem 100 % of the Company’s Public Shares if the Company has not consummated an initial Business Combination within the Completion Window or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial Business Combination activity. The proceeds deposited in the Trust Account could become subject to the claims of the Company’s creditors, if any, which could have priority over the claims of the Company’s public shareholders. The Company will provide its public shareholders with the opportunity to redeem all or a portion of their Public Shares upon the completion of the initial Business Combination either (i) in connection with a general meeting called to approve the initial Business Combination or (ii) without a shareholder vote by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a proposed initial Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The public shareholders will be entitled to redeem their Public Shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account calculated as of two business days prior to the consummation of the initial Business Combination, including interest earned on the funds held in the Trust Account (which interest shall be net of taxes paid or payable, excluding any 1 % U.S. federal excise tax on stock repurchases under the Inflation Reduction Act of 2022, or similar tax, that is imposed on us, if any), divided by the number of then outstanding Public Shares, subject to certain limitations. The ordinary shares subject to redemption were recorded at a redemption value and classified as temporary equity upon the completion of the Initial Public Offering, in accordance with Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” The Company will have the Completion Window to complete the initial Business Combination. However, if the Company is unable to complete its initial Business Combination within the Completion Window, the Company will as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account (less taxes payable and up to $ 100,000 of interest to pay liquidation expenses), divided by the number of then outstanding Public Shares, which redemption will constitute full and complete payment for the Public Shares and completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), subject to the Company’s obligations under Cayman Islands law to provide for claims of creditors and subject to the other requirements of applicable law. There will be no redemption rights or liquidating distributions with respect to our Warrants, which will expire worthless if the Company fails to complete the initial Business Combination within the Completion Window. 6 Table of Contents IDEA ACQUISITION CORP. NOTES TO CONDENSED FINANCIAL STATEMENTS JUNE 30, 2026 (Unaudited) The Sponsor and the Company’s officers and directors have entered into a letter agreement with the Company, dated February 10, 2026, pursuant to which they have agreed to (i) waive their redemption rights with respect to their Founder Shares (as described in Note 5) and any Public Shares in connection with the completion of the initial Business Combination; (ii) waive their redemption rights with respect to their Founder Shares and any Public Shares in connection with a shareholder vote to approve an amendment to the Company’s amended and restated memorandum and articles of association (A) to modify the substance or timing of the Company’s obligation to allow redemption in connection with the initial Business Combination or to redeem 100 % of the Public Shares if the Company has not consummated an initial Business Combination within the Completion Window or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial Business Combination activity; (iii) waive their rights to liquidating distributions from the Trust Account with respect to their Founder Shares if the Company fails to complete the initial Business Combination within the Completion Window, although they will be entitled to liquidating distributions from the Trust Account with respect to any Public Shares they hold if the Company fails to complete the initial Business Combination within the Completion Window and to liquidating distributions from assets outside the Trust Account; and (iv) vote the Founder Shares held by them and any Public Shares purchased during or after the Initial Public Offering (including in open market and privately-negotiated transactions) in favor of the initial Business Combination. The Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or other similar agreement or Business Combination agreement (except for the Company’s independent registered public accounting firm), reduce the amount of funds in the Trust Account to below the lesser of (i) $ 10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $ 10.00 per share due to reductions in the value of the Trust Account assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company’s indemnity of the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). However, the Company has not asked the Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and the Company believes that the Sponsor’s only assets are securities of the Company. Therefore, the Company cannot assure that the Sponsor would be able to satisfy those obligations. NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 8 of Regulation S-X of the U.S. Securities and Exchange Commission (“SEC”). Certain information or footnote disclosures normally included in 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, 2025 as filed with the SEC on March 31, 2026, as well as the Company’s Current Report on Form 8-K, as filed with the SEC on February 20, 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. Going Concern and Capital Resources The Company’s liquidity needs up to February 12, 2026 had been satisfied through the loan under an unsecured promissory note from the Sponsor of up to $ 300,000 . As of June 30, 2026, the Company had $ 1,168,048 of cash and had a working capital surplus of $ 878,328 . 7 Table of Contents IDEA ACQUISITION CORP. NOTES TO CONDENSED FINANCIAL STATEMENTS JUNE 30, 2026 (Unaudited) In order to finance transaction costs in connection with an initial Business Combination, the Sponsor or an affiliate of the Sponsor or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required (the “Working Capital Loans”). If the Company completes an initial Business Combination, the Company will repay such Working Capital Loans at that time. In the event that an initial Business Combination does not close, the Company may use a portion of the working capital held outside the Trust Account to repay the Working Capital Loans, including the repayment of loans from the Sponsor to pay for any amount deposited to pay for any extension of the Completion Window, but no proceeds from the Trust Account would be used for such repayment. Up to $ 1,500,000 of the Working Capital Loans may be converted into Private Placement Warrants of the post-Business Combination entity, at a price of $ 1.50 per warrant at the option of the lender. The warrants would be identical to the Private Placement Warrants. The terms of such Working Capital Loans by the Company’s officers and directors, if any, have not been determined and no written agreements exist with respect to such loans. As of June 30, 2026 and December 31, 2025, no such Working Capital Loans were outstanding. The Company has established an operating bank account; however, the cash balance in the account was $ 1,168,048 as of June 30, 2026. Certain operating and offering expenses were paid on behalf of the Company by the Sponsor and reduced the stock subscription receivable balance. In connection with the Company’s assessment of going concern considerations in accordance with ASC 205-40, management evaluated the Company’s liquidity and the mandatory liquidation date. The Company has projected negative cash flows and, unless it completes an initial Business Combination or obtains additional financing, may not have sufficient liquidity to meet its obligations through the mandatory liquidation date. Accordingly, management concluded that these conditions raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date these unaudited condensed financial statements are issued. Emerging Growth Company As an “emerging growth company”, as defined in Section 2(a) of the Securities Act and as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), the Company 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 non-binding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. 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 an emerging growth 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 financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Use of Estimates The preparation of the unaudited condensed financial statements in conformity with GAAP requires the Company’s 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. 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 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 from those estimates. 8 Table of Contents IDEA ACQUISITION CORP. NOTES TO CONDENSED FINANCIAL STATEMENTS JUNE 30, 2026 (Unaudited) 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 $ 1,168,048 of cash equivalents and had $ 0 cash as of June 30, 2026 and December 31, 2025, respectively. Cash and Marketable Securities Held in Trust Account As of June 30, 2026, the assets held in the Trust Account, amounting to $ 354,671,436 , were invested in U.S. Treasury securities through a government money market fund. There were no assets held in the Trust Account as of December 31, 2025. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation coverage limit of $250,000. Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company’s financial condition, results of operations, and cash flows. Offering Costs Associated with the Initial Public Offering The Company complies with the requirements of the FASB ASC Topic 340-10-S99 and SEC Staff Accounting Bulletin Topic 5A, “Expenses of Offering.” Offering costs consist principally of professional and registration fees that are related to the Initial Public Offering. FASB ASC Topic 470-20, “Debt with Conversion and Other Options,” addresses the allocation of proceeds from the issuance of convertible debt into its equity and debt components. The Company applies this guidance to allocate Initial Public Offering proceeds from the Units between Class A ordinary shares and Warrants, using the residual method by allocating Initial Public Offering proceeds first to assigned value of the Warrants and then to the Class A ordinary shares. Offering costs allocated to the Class A ordinary shares were charged to temporary equity and offering costs allocated to the Public Warrants (as described in Note 3) and Private Placement Warrants were charged to shareholders’ deficit as Public Warrants and Private Placement Warrants after management’s evaluation are accounted for under equity treatment. Income Taxes The Company accounts for income taxes under FASB ASC Topic 740, “Income Taxes,” which requires an asset and liability approach to financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed for differences between the unaudited condensed financial statements and tax bases of assets and liabilities that will result in future taxable or deductible amounts, based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. FASB ASC Topic 740 prescribes a recognition threshold and a measurement attribute for the unaudited condensed financial statements recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company’s management determined that the Cayman Islands is the Company’s major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. As of June 30, 2026 and December 31, 2025, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is considered to be an exempted Cayman Islands company with no connection to any other taxable jurisdiction and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company’s tax provision was zero for the periods presented. 9 Table of Contents IDEA ACQUISITION CORP. NOTES TO CONDENSED FINANCIAL STATEMENTS JUNE 30, 2026 (Unaudited) Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under the FASB ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the condensed balance sheets, primarily due to their short-term nature. Derivative Financial Instruments The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with FASB ASC Topic 815, “Derivatives and Hedging”. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then re-valued at each reporting date, with changes in the fair value reported in the unaudited condensed statement of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative liabilities are classified in the 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 sheets date. The underwriters’ over-allotment option is deemed to be a freestanding financial instrument indexed on the shares subject to redemption and are accounted for as a liability pursuant to FASB ASC Topic 480 since the underwriters’ over-allotment option was not exercised in full at the time of the Initial Public Offering. No derivative liabilities were outstanding as of June 30, 2026 and December 31, 2025. Warrants The Company accounts for the Public Warrants and Private Placement Warrants issued in connection with the Initial Public Offering 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. Class A Ordinary Shares Subject to Possible Redemption The Public Shares contain a redemption feature which allows for the redemption of such Public Shares in connection with the Company’s liquidation, or if there is a shareholder vote or tender offer in connection with the Company’s initial Business Combination. In accordance with FASB ASC Topic 480-10-S99, the Company classifies Public Shares subject to possible redemption outside of permanent equity as the redemption provisions are not solely within the control of the Company. The Company recognizes changes in redemption value immediately as they occur and will adjust the carrying value of redeemable shares to equal the redemption value at the end of each reporting period. Immediately upon the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption value. The change in the carrying value of redeemable shares will result in charges against additional paid-in capital (to the extent available) and accumulated deficit. Accordingly, as of 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 balance sheets. As of June 30, 2026 and December 31, 2025, the Class A ordinary shares subject to possible redemption reflected in the condensed balance sheets are reconciled in the following table: ​ ​ ​ ​ ​ Gross proceeds ​ ​ ​ $ 350,000,000 Less: ​ ​ Proceeds allocated to Public Warrants ​ ( 3,885,000 ) Proceeds allocated to over-allotment ​ ( 326,700 ) Public Shares issuance costs ​ ( 21,385,751 ) Plus: ​ ​ ​ Remeasurement of carrying value to redemption value ​ ​ 27,186,722 Class A ordinary shares subject to possible redemption, March 31, 2026 ​ $ 351,589,271 Plus: ​ ​ Remeasurement of carrying value to redemption value ​ 3,082,165 Class A ordinary shares subject to possible redemption, June 30, 2026 ​ $ 354,671,436 ​ 10 Table of Contents IDEA ACQUISITION CORP. NOTES TO CONDENSED FINANCIAL STATEMENTS JUNE 30, 2026 (Unaudited) Net Income (Loss) per Ordinary Share The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as Class A ordinary shares and Class B ordinary shares. Certain of its Class A ordinary shares are redeemable and certain of its Class A ordinary shares are non-redeemable. Income and losses are shared pro rata between its Class A redeemable shares and its Class B non-redeemable shares. This presentation assumes an initial Business Combination as the most likely outcome. The Company does not have any dilutive instruments. Net income (loss) per ordinary share is calculated by dividing the net income (loss) by the weighted average shares of ordinary shares outstanding for the respective period. Accretion associated with the Class A ordinary shares subject to possible redemption is excluded from earnings per share as the redemption value approximates fair value. The following tables reflect the calculation of basic and diluted net income (loss) per ordinary share (in dollars, except per share amounts): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Three Months Ended ​ ​ June 30, 2026 ​ ​ Class A ​ ​ ​ Class B Basic and diluted net income per ordinary share: ​ ​ ​ ​ ​ ​ Numerator: ​ ​ ​ ​ Allocation of net income ​ $ 2,283,102 ​ $ 570,776 Denominator: ​ ​ ​ ​ Basic and diluted weighted average ordinary shares outstanding ​ 35,000,000 ​ 8,750,000 Basic and diluted net income per ordinary share ​ $ 0.07 ​ $ 0.07 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Six Months Ended ​ ​ June 30, 2026 ​ ​ ​ ​ Class A ​ ​ ​ Class B Basic and diluted net loss per ordinary share: ​ ​ ​ ​ Numerator: ​ ​ ​ ​ Allocation of net loss ​ $ ( 1,150,687 ) ​ $ ( 404,199 ) Denominator: ​ ​ ​ ​ Basic and diluted weighted average ordinary shares outstanding ​ 26,685,083 ​ 9,373,619 Basic and diluted net loss per ordinary share ​ $ ( 0.04 ) ​ $ ( 0.04 ) ​ 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 applies 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 by multiplying the marketable value per founder share (defined in Note 5) by the probability of successful closing of an initial Business Combination. 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. Share-based compensation expense is recognized over the requisite service period, which is generally the vesting period, unless the awards are fully vested upon grant. For awards that are fully vested and not subject to future service or performance conditions, compensation expense is recognized immediately on the grant date. If vesting does not occur, any previously recognized compensation cost is reversed in the period related to the termination of service. 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 the Company’s unaudited condensed financial statements. 11 Table of Contents IDEA ACQUISITION CORP. NOTES TO CONDENSED FINANCIAL STATEMENTS JUNE 30, 2026 (Unaudited) NOTE 3. INITIAL PUBLIC OFFERING Pursuant to the closing of the Initial Public Offering on February 12, 2026, the Company sold 35,000,000 Units, at a purchase price of $ 10.00 per Unit, generating gross proceeds of $ 350,000,000 . Each Unit consists of one Class A ordinary share and one -third of one redeemable 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 7). NOTE 4. PRIVATE PLACEMENT Simultaneously with the closing of the Initial Public Offering on February 12, 2026, the Sponsor and the Underwriters purchased in a private placement an aggregate of 6,000,000 Private Placement Warrants, each exercisable to purchase one Class A ordinary share at $ 11.50 per share, at a price of $ 1.50 per Private Placement Warrant, generating gross proceeds of $ 9,000,000 . Of those 6,000,000 Private Placement Warrants, the Sponsor purchased 3,666,667 Private Placement Warrants and the Underwriters purchased an aggregate of 2,333,333 Private Placement Warrants. Each whole Private Placement Warrant entitles the registered holder to purchase one Class A ordinary share at a price of $ 11.50 per share, subject to adjustment. NOTE 5. RELATED PARTY TRANSACTIONS Founder Shares On September 22, 2025, the Sponsor was issued 10,062,500 Class B ordinary shares (the “Founder Shares”) for an aggregate price of $ 25,000 paid to cover certain expenses on behalf of the Company. The Founder Shares included an aggregate of up to 1,312,500 Class B ordinary shares subject to forfeiture by the Sponsor to the extent that the Underwriters’ over-allotment option was not exercised in full or in part. The Underwriters did not exercise their over-allotment option in full or in part. As a result, on March 27, 2026, the Sponsor forfeited, at no cost, 1,312,500 Class B ordinary shares to the Company. The Company’s initial shareholders have agreed not to transfer, assign or sell any of their Founder Shares and any Class A ordinary shares issued upon conversion thereof until the earlier to occur of (i) one year after the completion of the initial Business Combination or (ii) the date on which the Company completes a liquidation, merger, share exchange or other similar transaction after the initial Business Combination that results in all of the Company’s shareholders having the right to exchange their Class A ordinary shares for cash, securities or other property. Any permitted transferees will be subject to the same restrictions and other agreements of the Company’s initial shareholders with respect to any Founder Shares (the “Lock-up”). Notwithstanding the foregoing, if (1) the closing price of the Class A ordinary shares equals or exceeds $ 12.00 per share (as adjusted for share subdivisions, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30 -trading day period commencing at least 150 days after the initial Business Combination or (2) if the Company consummates a transaction after the initial Business Combination which results in the Company’s shareholders having the right to exchange their shares for cash, securities or other property, the Founder Shares will be released from the Lock-up. Share Based Compensation On February 10, 2026, the Sponsor granted membership interests in Idea Tender LLC equivalent to an aggregate of 2,100,000 Founder Shares and 879,997 Private Placement Warrants to certain independent directors and an officer of the Company. The independent directors received membership interests equivalent to 2,000,000 Founder Shares and 838,093 Private Placement Warrants, and the Chief Financial Officer received membership interests equivalent to 100,000 Founder Shares and 41,904 Private Placement Warrants. The awards are within the scope of ASC 718 and were determined to be equity-classified awards. Accordingly, the awards were measured at their grant-date fair value and will not be subsequently remeasured. The grant-date fair value of the Founder Shares was determined using a third-party valuation model that considered, among other assumptions, (i) an implied share price of $ 9.88 , (ii) a risk-free interest rate of 3.65 %, and (iii) a probability-weighted de-SPAC and market adjustment factor of 28.37 %. The grant-date fair value of the Private Placement Warrants was based on the fair value of the Public Warrants, as further described in Note 8. 12 Table of Contents IDEA ACQUISITION CORP. NOTES TO CONDENSED FINANCIAL STATEMENTS JUNE 30, 2026 (Unaudited) On the grant date, the Founder Shares had an aggregate fair value of approximately $ 5.9 million, or $ 2.80 per share, and the Private Placement Warrants had an aggregate fair value of approximately $ 0.3 million, or $ 0.33 per warrant. Because the Founder Shares were fully vested upon grant and not subject to any future service or performance conditions, the Company recognized the full fair value of the Founder Shares as share-based compensation expense on February 10, 2026. Promissory Note - Related Party The Sponsor has agreed to loan the Company an aggregate of up to $ 300,000 to be used for a portion of the expenses of the Initial Public Offering. The loan was non-interest bearing, unsecured and due at the earlier of June 30, 2026 or the closing of the Initial Public Offering. The Company had borrowed $ 250,689 under the promissory note which is still outstanding at June 30, 2026 and is due on demand. Borrowings under the promissory note are no longer available. Share Subscription Receivable On February 12, 2026, in connection with the sale of the Private Placement Warrants, the Sponsor should have deposited $ 2,000,000 into the Company’s bank account. Due to the timing of funds and the bank account opening process, these funds were not deposited on the expected date, and the Company had accounted for the amount due as a share subscription receivable within equity. Certain operating and offering expenses paid by the Sponsor on behalf of the Company reduced the outstanding share subscription receivable balance. On May 15, 2026, the Sponsor paid the remaining $ 2,000,000 , and the share subscription receivable was fully settled. Accordingly. As of June 30, 2026, there was no outstanding balance in the accompanying condensed balance sheet. Administrative Services and Indemnification Agreement Commencing on February 10, 2026, the Company entered into an agreement with the Sponsor to pay an aggregate of $ 20,000 per month for office space, secretarial and administrative services provided to members of the management team. These monthly fees will cease upon the earlier of the completion of the initial Business Combination or the liquidation of the Company. For the three and six months ended June 30, 2026, the Company incurred $ 92,857 of administrative services fees which was included in accrued expenses in the accompanying condensed balance sheets. Related Party Loans In order to finance transaction costs in connection with an initial Business Combination, the Sponsor or an affiliate of the Sponsor or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required. If the Company completes an initial Business Combination, the Company will repay such loaned amounts. In the event that initial Business Combination does not close, the Company may use a portion of the working capital held outside the Trust Account to repay such loaned amounts, including the repayment of loans from the Sponsor to pay for any amount deposited to pay for any extension of the time to complete an initial Business Combination, but no proceeds from the Trust Account would be used for such repayment. Up to $ 1,500,000 of such loans may be convertible into Private Placement Warrants of the post Business Combination entity, at a price of $ 1.50 per warrant at the option of the lender. The warrants would be identical to the Private Placement Warrants. The terms of such loans by the Company’s officers and directors, if any, have not been determined and no written agreements exist with respect to such loans. As of June 30, 2026 and December 31, 2025, no such Working Capital Loans were outstanding. 13 Table of Contents IDEA ACQUISITION CORP. NOTES TO CONDENSED FINANCIAL STATEMENTS JUNE 30, 2026 (Unaudited) NOTE 6. COMMITMENTS 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. Registration Rights Agreement The holders of the (i) Founder Shares, (ii) Private Placement Warrants and the Class A ordinary shares underlying such Private Placement Warrants and (iii) Private Placement Warrants that may be issued upon conversion of the Working Capital Loans have registration rights to require the Company to register a sale of any of the Company’s securities held by them and any other securities of the Company acquired by them prior to the consummation of the initial Business Combination pursuant to a registration rights agreement signed on the effective date of the Initial Public Offering. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company registers such securities. In addition, the holders have certain piggyback registration rights with respect to registration statements filed subsequent to the completion of the initial Business Combination. In addition, the Underwriters may participate in a piggyback registration only during the seven-year period beginning on the effective date of the Initial Public Offering. The Company will bear the expenses incurred in connection with the filing of any such registration statements. Underwriting Agreement The Underwriters had a 45 -day option from the date of the Initial Public Offering to purchase up to an additional 5,250,000 Units to cover over-allotments. The Underwriters did not exercise their over-allotment option in full or in part. As a result, on March 27, 2026, the Sponsor forfeited, at no t cost, 1,312,500 Class B ordinary shares to the Company. The Underwriters received a cash underwriting discount of $ 7,000,000 ( 2.0 % of the gross proceeds of the Units offered in the Initial Public Offering). Additionally, the Underwriters are entitled to a deferred underwriting discount of 4.0 % of the gross proceeds of the Initial Public Offering held in the Trust Account. NOTE 7. STOCKHOLDERS’ DEFICIT Preference shares - The Company is authorized to issue 5,000,000 preference shares with a par value of $ 0.0001 per share. 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 500,000,000 Class A ordinary shares with a par value of $ 0.0001 per share. As of June 30, 2026, there were no Class A ordinary shares issued or outstanding, excluding 35,000,000 shares subject to possible redemption. At December 31, 2025, there were no Class A ordinary shares issued or outstanding. Class B ordinary shares - The Company is authorized to issue 50,000,000 Class B ordinary shares with a par value of $ 0.0001 per share. As of June 30, 2026, there were 8,750,000 Class B ordinary shares issued and outstanding. As of December 31, 2025, there were 10,062,500 Class B ordinary shares issued and outstanding. 14 Table of Contents IDEA ACQUISITION CORP. NOTES TO CONDENSED FINANCIAL STATEMENTS JUNE 30, 2026 (Unaudited) The Founder Shares will automatically convert into Class A ordinary shares concurrently with or immediately following the consummation of the initial Business Combination or earlier at the option of the holder on a one -for-one basis, subject to adjustment for share subdivisions, share capitalizations, reorganizations, recapitalizations and the like, and subject to further adjustment as provided herein. In the case that additional Class A ordinary shares, or any other equity-linked securities, are issued or deemed issued in excess of the amounts sold in the Initial Public Offering and related to or in connection with the closing of the initial Business Combination, the ratio at which Class B ordinary shares convert into Class A ordinary shares will be adjusted (unless the holders of a majority of the outstanding Class B ordinary shares agree to waive such adjustment with respect to any such issuance or deemed issuance) so that the number of Class A ordinary shares issuable upon conversion of all Class B ordinary shares will equal, in the aggregate, 20 % of the sum of (i) the total number of all ordinary shares outstanding upon the completion of the Initial Public Offering (including any Class A ordinary shares issued pursuant to the Underwriters’ over-allotment option and excluding the Class A ordinary shares underlying the Private Placement Warrants issued to the Sponsor), plus (ii) all Class A ordinary shares and equity-linked securities issued or deemed issued, in connection with the closing of the initial Business Combination (excluding any shares or equity-linked securities issued, or to be issued, to any seller in the initial Business Combination and any Private Placement-equivalent Warrants issued to the Sponsor or any of its affiliates or to the Company’s officers or directors upon conversion of working capital loans) minus (iii) any redemptions of Class A ordinary shares by public shareholders in connection with an initial Business Combination; provided that such conversion of Founder Shares will never occur on a less than one -for-one basis. Holders of record of the Company’s Class A ordinary shares and Class B ordinary shares are entitled to one vote for each share held on all matters to be voted on by shareholders. Unless specified in the amended and restated memorandum and articles of association or as required by the Companies Act or stock exchange rules, an ordinary resolution under Cayman Islands law and the amended and restated memorandum and articles of association, which requires the affirmative vote of at least a majority of the votes cast by such shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the applicable general meeting of the company is generally required to approve any matter voted on by the Company’s shareholders. Approval of certain actions require a special resolution under Cayman Islands law, which (except as specified below) requires the affirmative vote of at least two-thirds of the votes cast by such shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the applicable general meeting, and pursuant to the Company’s amended and restated memorandum and articles of association, such actions include amending the amended and restated memorandum and articles of association and approving a statutory merger or consolidation with another company. There is no cumulative voting with respect to the appointment of directors, meaning, following the Company’s initial Business Combination, the holders of more than 50 % of the ordinary shares voted for the appointment of directors can elect all of the directors. Prior to the consummation of the initial Business Combination, only holders of the Class B ordinary shares will (i) have the right to vote on the appointment and removal of directors and (ii) be entitled to vote on continuing the Company in a jurisdiction outside the Cayman Islands (including any special resolution required to amend the constitutional documents or to adopt new constitutional documents, in each case, as a result of approving a transfer by way of continuation in a jurisdiction outside the Cayman Islands). Holders of the Class A ordinary shares will not be entitled to vote on these matters during such time. These provisions of the amended and restated memorandum and articles of association may only be amended if approved by a special resolution passed by the affirmative vote of at least 90 % (or, where such amendment is proposed in respect of the consummation of the initial Business Combination, two-thirds ) of the votes cast by such shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the applicable general meeting of the Company. Warrants – As of June 30, 2026, there were 11,666,667 Public Warrants and 6,000,000 Private Placement Warrants outstanding. At December 31, 2025, there were no Warrants outstanding. Each whole Warrant entitles the holder to purchase one Class A ordinary share at a price of $ 11.50 per share, subject to adjustment as discussed herein. The Warrants cannot be exercised until 30 days after the completion of the initial Business Combination, and will expire at 5:00 p.m., New York City time, five years after the completion of the initial Business Combination or earlier upon redemption or liquidation. 15 Table of Contents IDEA ACQUISITION CORP. NOTES TO CONDENSED FINANCIAL STATEMENTS JUNE 30, 2026 (Unaudited) The Company will not be obligated to deliver any Class A ordinary shares pursuant to the exercise of a Warrant and will have no obligation to settle such Warrant exercise unless a registration statement under the Securities Act with respect to the Class A ordinary shares underlying the Warrants is then effective and a prospectus relating thereto is current. No Warrant will be exercisable and the Company will not be obligated to issue a Class A ordinary share upon exercise of a Warrant unless the Class A ordinary share issuable upon such Warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the Warrants. In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a Warrant, the holder of such Warrant will not be entitled to exercise such Warrant and such Warrant may have no value and expire worthless. In no event will the Company be required to net cash settle any Warrant. In the event that a registration statement is not effective for the exercised Warrants, the purchaser of a Unit containing such Warrants will have paid the full purchase price for the Unit solely for the Class A ordinary share underlying such Unit. Under the terms of the Warrant agreement, the Company has agreed that, as soon as practicable, but in no event later than 20 business days after the closing of its Business Combination, it will use commercially reasonable efforts to file with the SEC a post-effective amendment to the registration statement for the Initial Public Offering or a new registration statement covering the registration under the Securities Act of the Class A ordinary shares issuable upon exercise of the Warrants and thereafter will use its commercially reasonable efforts to cause the same to become effective within 60 business days following the Company’s initial Business Combination and to maintain a current prospectus relating to the Class A ordinary shares issuable upon exercise of the Warrants until the expiration of the Warrants in accordance with the provisions of the Warrant agreement. If a registration statement covering the Class A ordinary shares issuable upon exercise of the Warrants is not effective by the sixtieth (60th) business day after the closing of the initial Business Combination, Warrant holders may, until such time as there is an effective registration statement and during any period when the Company will have failed to maintain an effective registration statement, exercise Warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption. Notwithstanding the above, if the Class A ordinary shares are at the time of any exercise of a Warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their Warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elects, the Company will not be required to file or maintain in effect a registration statement, and in the event the Company does not so elect, the Company will use its commercially reasonable efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available. If the holders exercise their Public Warrants on a cashless basis, they would pay the Warrant exercise price by surrendering the Warrants for that number of Class A ordinary shares equal to the quotient obtained by dividing (x) the product of the number of Class A ordinary shares underlying the Warrants, multiplied by the excess of the “fair market value” of the Class A ordinary shares over the exercise price of the Warrants by (y) the fair market value. The “fair market value” is the average reported closing price of the Class A ordinary shares for the 10 trading days ending on the third trading day prior to the date on which the notice of exercise is received by the Warrant agent or on which the notice of redemption is sent to the holders of Warrants, as applicable. Redemption of Warrants When the Price per Class A Ordinary Share Equals or Exceeds $ 18.00 : The Company may redeem the outstanding Warrants: ● in whole and not in part; ● at a price of $ 0.01 per warrant; ● upon a minimum of 30 days ’ prior written notice of redemption (the “30-day redemption period”); and ● if, and only if, the closing price of the Class A ordinary shares equals or exceeds $ 18.00 per share (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a warrant) for any 20 trading days within a 30 -trading day period commencing at least 30 days after completion of the Company’s initial Business Combination and ending three business days before the Company sends the notice of redemption to the warrant holders. 16 Table of Contents IDEA ACQUISITION CORP. NOTES TO CONDENSED FINANCIAL STATEMENTS JUNE 30, 2026 (Unaudited) Additionally, if the number of outstanding Class A ordinary shares is increased by a share capitalization payable in Class A ordinary shares, or by a subdivision of ordinary shares or other similar event, then, on the effective date of such share capitalization, subdivision or similar event, the number of Class A ordinary shares issuable on exercise of each warrant will be increased in proportion to such increase in the outstanding ordinary shares. A rights offering made to all or substantially all holders of ordinary shares entitling holders to purchase Class A ordinary shares at a price less than the fair market value will be deemed a share capitalization of a number of Class A ordinary shares equal to the product of (i) the number of Class A ordinary shares actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for Class A ordinary shares) and (ii) the quotient of (x) the price per Class A ordinary share paid in such rights offering and (y) the fair market value. For these purposes (i) if the rights offering is for securities convertible into or exercisable for Class A ordinary shares, in determining the price payable for Class A ordinary shares, there will be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) fair market value means the volume weighted average price of Class A ordinary shares as reported during the ten ( 10 ) trading day period ending on the trading day prior to the first date on which the Class A ordinary shares trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights. NOTE 8. FAIR VALUE MEASUREMENTS Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include: ● Level 1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets; ● Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and ● Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. The following table presents information about the Company’s assets that are measured at fair value as of June 30, 2026 and December 31, 2025 and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ ​ ​ December 31, Description ​ Level ​ 2026 ​ 2025 Assets: ​ ​ ​ ​ ​ ​ ​ ​ Cash and marketable securities held in Trust Account ​ 1 ​ $ 354,671,436 ​ $ — ​ The over-allotment option was accounted for as a liability in accordance with FASB ASC Topic 815-40 and was presented within liabilities on the condensed balance sheets. The over-allotment option liability is measured at fair value at inception and on a recurring basis, with changes in fair value presented within changes in fair value of over-allotment option liability in the unaudited condensed statement of operations. 17 Table of Contents IDEA ACQUISITION CORP. NOTES TO CONDENSED FINANCIAL STATEMENTS JUNE 30, 2026 (Unaudited) The fair value of the over-allotment option liability was $ 326,700 . The Company used a Black-Scholes model to value the over-allotment option. The over-allotment option liability was classified within Level 3 of the fair value hierarchy at the measurement dates due to the use of unobservable inputs inherent in pricing models are assumptions related to expected share-price volatility, expected life and risk-free interest rate. The Company estimates the volatility of its ordinary shares based on historical volatility that matches the expected remaining life of the option. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the option. The expected life of the option is assumed to be equivalent to their remaining contractual term. On March 27, 2026, the underwriters’ over-allotment option expired unexercised. Accordingly, the over-allotment option liability was reduced to zero as of June 30, 2026, and the related change in fair value was recognized in the unaudited condensed statement of operations for the three months ended March 31, 2026. The key inputs into the Black-Scholes model were as follows at initial measurement of the over-allotment option: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ February 12, ​ ​ 2026 ​ Volatility ​ 2.51 % Expected term (years) ​ 0.12 ​ Risk-free rate ​ 3.71 % Exercise price ​ $ 10.00 ​ Fair value of over-allotment unit ​ $ 0.06 ​ ​ The fair value of the Public Warrants issued in the Initial Public Offering was $ 3,885,000 , or $ 0.33 per Public Warrant and was determined using Monte Carlo Simulation Model. The Public Warrants issued in the Initial Public Offering have been classified within shareholders’ deficit and will not require remeasurement after issuance. The following table presents the quantitative information regarding market assumptions used in the Level 3 valuation of the Public Warrants issued in the Initial Public Offering: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ February 12, ​ ​ 2026 ​ Underlying stock price ​ $ 9.82 Exercise price ​ $ 11.50 ​ Volatility ​ 5.00 % Probability of De-SPAC and market adjustment ​ 27.7 % Risk-free rate ​ 3.80 % Warrant term (years) ​ 7.00 ​ ​ ​ NOTE 9. SEGMENT INFORMATION FASB ASC Topic 280, “Segment Reporting,” establishes standards for companies to report in their unaudited condensed 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 Executive Officer, who reviews the assets, operating results and financial metrics for the Company as a whole to make decisions about allocating resources and assessing financial performance. Accordingly, management has determined that the Company only has one reportable segment. 18 Table of Contents IDEA ACQUISITION CORP. NOTES TO CONDENSED FINANCIAL STATEMENTS JUNE 30, 2026 (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 statement 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 several key metrics, which include the following: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ ​ ​ December 31, ​ ​ 2026 ​ 2025 Cash and cash equivalents ​ $ 1,168,048 ​ $ — Cash and marketable securities held in Trust Account ​ $ 354,671,436 ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Three ​ ​ ​ For the Six ​ ​ Months Ended ​ Months Ended ​ ​ June 30, 2026 ​ June 30, 2026 General and administrative costs ​ $ 228,287 ​ $ 370,703 Interest earned on marketable securities held in Trust Account ​ $ 3,082,165 ​ $ 4,671,436 ​ The CODM reviews general and administrative costs to manage and forecast cash to ensure enough capital is available to complete an initial Business Combination or similar transaction within the Completion Window. The CODM also reviews general and administrative costs to manage, maintain and enforce all contractual agreements to ensure costs are aligned with all agreements and budget. General and administrative costs, as reported on the unaudited condensed statement of operations, are the significant segment expenses provided to the CODM on a regular basis. The CODM reviews the position of total assets as reported in the Company’s condensed balance sheets to assess if the Company has sufficient resources available to discharge its liabilities. The CODM is provided with details of cash and liquid resources available with the Company. Additionally, the CODM regularly reviews the status of deferred offering costs incurred to assess if these are in line with the planned use of proceeds raised from the Initial Public Offering. The CODM will review the interests and/or dividends that will be earned and accrued on investments held in Trust Account to measure and monitor shareholder value and determine the most effective strategy of investment with the Trust Account funds while maintaining compliance with the Trust Agreement. NOTE 10. SUBSEQUENT EVENTS The Company evaluated subsequent events and transactions that occurred after the condensed balance sheet dates through August 13, 2026, 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 unaudited condensed financial statements. ​ ​ 19 Table of Contents Item 2.

Words such as “expect,” “believe,” “anticipate,” “intend,” “estimate,” “seek” and variations and similar words and expressions are intended to identify such forward-looking statements. Such forward-looking statements relate to future events or future performance, but reflect management’s current beliefs, based on information currently available. A number of factors could cause actual events, performance or results to differ materially from the events, performance and results discussed in the forward-looking statements, including that the conditions of the Business Combination are not satisfied. For information identifying important factors that could cause actual results to differ materially from those anticipated in the forward-looking statements, please refer to the Risk Factors section of the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 as filed with the SEC on March 31, 2026. 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 September 18, 2025. We are formed for the purpose of effecting a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or similar Business Combination with one or more businesses. We may pursue an initial Business Combination in any business or industry but expect to target opportunities and companies that are operating in the software vertical that leverages large language models or other AI tools. 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 revenues to date. Our only activities from September 18, 2025 (inception) through June 30, 2026 were organizational activities, those necessary to prepare for the Initial Public Offering, described below, and identifying a target company for a Business Combination. We do not expect to generate any operating revenues until after the completion of our Business Combination. We generate non-operating income in the form of interest income on marketable securities held in the Trust Account. We incur expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), as well as for due diligence expenses. For the three months ended June 30, 2026, we had a net income of $2,853,878 which consists of interest income on marketable securities held in the Trust Account of $3,082,165, offset by operating costs of $228,287. For the six months ended June 30, 2026, we had a net loss of $1,554,886, which consists of operating costs of $370,703 and compensation expense of $6,182,319, offset by interest income on marketable securities held in the Trust Account of $4,671,436 and change in overallotment liability of $326,700. The weighted average number of Class A ordinary shares outstanding for the three and six months ended June 30, 2026 reflects the timing of the consummation of the Company’s Initial Public Offering on February 12, 2026. Accordingly, the weighted average shares outstanding for the period represent the portion of the quarter during which the Public Shares were outstanding. 20 Table of Contents Going Concern and Capital Resources Until the consummation of the Initial Public Offering, our only source of liquidity was an initial purchase of shares, par value $0.0001 per share, by the Sponsor and loans from the Sponsor. On February 12, 2026, we consummated the Initial Public Offering of 35,000,000 Units at $10.00 per Unit, generating gross proceeds of $350,000,000. Simultaneously with the closing of the Initial Public Offering, we consummated the sale of an aggregate of 6,000,000 Private Placement Warrants, at a price of $1.50 per Private Placement Warrant, in a private placement to the Sponsor and the Underwriters, generating gross proceeds of $9,000,000. Certain operating and offering expenses have been paid on behalf of the Company by the Sponsor and reduced the outstanding share subscription receivable balance. Following the Initial Public Offering and the sale of the Private Placement Warrants, a total of $350,000,000 was placed in the Trust Account. We incurred $21,662,847 in IPO related costs, consisting of $7,000,000 of cash underwriting fees, $14,000,000 of deferred underwriting fees, and $662,847 of other costs. For the six months ended June 30, 2026, cash used in operating activities was $502,373. Net loss of $1,554,886 was affected by interest earned on marketable securities held in the Trust Account of $4,671,436, compensation expense of $6,182,319 and change in fair value of overallotment liability of $326,700. Changes in operating assets and liabilities used $131,670 of cash for operating activities. The compensation expense primarily related to the grant of membership interests equivalent to Founder Shares and Private Placement Warrants by the Sponsor to certain independent directors and an officer of the Company. The awards were accounted for as equity-classified share-based compensation under ASC 718 and were measured at grant-date fair value. Because the awards were fully vested upon grant and not subject to future service conditions, the full fair value of the awards was recognized immediately as non-cash compensation expense during the period. As of June 30, 2026, we had marketable securities held in the Trust Account of $354,671,436 (including approximately $4,671,436 of interest income) consisting of U.S. Treasury Bills with a maturity of 185 days or less. We may withdraw interest from the Trust Account to pay taxes, if any. We intend to use substantially all of the funds held in the Trust Account, including any amounts representing earnings on the Trust Account (less taxes payable, if any), to complete our Business Combination. To the extent that our share capital or debt is used, in whole or in part, as consideration to complete our Business Combination, the remaining proceeds held in the Trust Account will be used as working capital to finance the operations of the target business or businesses, make other acquisitions and pursue our growth strategies. As of June 30, 2026, we had $1,168,048 of cash. We intend to use the funds held outside the Trust Account primarily to identify and evaluate target businesses, perform business due diligence on prospective target businesses, travel to and from the offices, plants or similar locations of prospective target businesses or their representatives or owners, review corporate documents and material agreements of prospective target businesses, and structure, negotiate and complete a Business Combination. In order to fund working capital deficiencies or finance transaction costs in connection with a Business Combination, the Sponsor or certain of our officers and directors or their affiliates may, but are not obligated to, loan us funds as may be required. If we complete a Business Combination, we would repay such loaned amounts. In the event that a Business Combination does not close, we may use a portion of the working capital held outside the Trust Account to repay such loaned amounts, but no proceeds from our Trust Account would be used for such repayment. Up to $1,500,000 of such Working Capital Loans may be convertible into Private Placement Warrants of the post-Business Combination entity, at a price of $1.50 per warrant at the option of the lender, upon consummation of an initial Business Combination. The warrants would be identical to the Private Placement Warrants. In connection with the Company’s assessment of going concern considerations in accordance with ASC 205-40, management evaluated the Company’s liquidity and mandatory liquidation date. Management determined that the Company’s projected cash flows and mandatory liquidation date raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date these unaudited condensed financial statements are issued. Management’s plans are discussed above; however, there can be no assurance that such plans will be successfully implemented. 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. 21 Table of Contents Contractual obligations Administrative Services and Indemnification Agreement We do not have any long-term debt, capital lease obligations, operating lease obligations or long-term liabilities, other than the Administrative Services and Indemnification Agreement (see Note 5). The Company agreed to indemnify and hold harmless the Sponsor and the Company’s directors, officers, employees, principals, managers, partners, members, shareholders, equity holders, control persons, affiliates, agents, advisors, consultants and representatives (the “Indemnitees”) from any claims, losses, liabilities, obligations, causes of action, proceedings (whether pending or threatened), investigations, damages, awards, settlements, judgments, decrees, fees, costs, penalties, amounts paid in settlement or expenses (including interest, assessments and other charges in connection therewith and reasonable fees and disbursements of attorneys and other professional advisors and costs of suit) arising out of or relating to any pending or threatened claim, action, suit, proceeding or investigation against any of them or in which any of them may be a participant or may otherwise be involved (including as a witness) that arises out of or relates to (i) the IPO of the Company’s securities or the Company’s operations or conduct of its business (including, for the avoidance of doubt, a Business Combination), or (ii) any claim against the Sponsor alleging any expressed or implied management or endorsement by the Sponsor of any activities of the Company or any express or implied association between the Sponsor, on the one hand, and the Company or any of its affiliates, on the other hand. Underwriting Agreement The Underwriters received a cash underwriting discount of $0.20 per Unit sold in the IPO, or $7,000,000 in the aggregate. In addition, the Underwriters are entitled to a deferred underwriting fee of $0.40 per Unit sold in the IPO, or $14,000,000 in the aggregate. 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, but such $0.40 per Unit shall be due to the Underwriters solely on amounts remaining in the Trust Account following all properly submitted shareholder redemptions, including in connection with the consummation of the Company’s initial Business Combination, subject to the terms of the underwriting agreement. Registration Rights Agreement The holders of the (i) Founder Shares, (ii) Private Placement Warrants and the Class A ordinary shares underlying such Private Placement Warrants and (iii) Private Placement Warrants that may be issued upon conversion of the Working Capital Loans have registration rights to require the Company to register a sale of any of the Company’s securities held by them and any other securities of the Company acquired by them prior to the consummation of the initial Business Combination pursuant to a registration rights agreement signed on the effective date of the Initial Public Offering. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company registers such securities. In addition, the holders have certain piggyback registration rights with respect to registration statements filed subsequent to the completion of the initial Business Combination. In addition, Cantor may participate in a piggyback registration only during the seven-year period beginning on the effective date of the Initial Public Offering. The Company will bear the expenses incurred in connection with the filing of any such registration statements. Critical Accounting Estimates The preparation of the unaudited condensed financial statements and related disclosures in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the unaudited condensed financial statements, and income and expenses during the period reported. Making estimates requires management to exercise significant judgement. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the unaudited condensed financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could materially differ from those estimates. As of June 30, 2026, we did not have any critical accounting estimates to be disclosed. Recent Accounting Standards Management does not believe that any recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on our unaudited condensed financial statements. 22 Table of Contents Item 3. Quantitative and Qualitative Disclosures About Market Risk We are a smaller reporting company as defined by Rule 12b-2 of the Securities Exchange Act of 1934, as amended, and are not required to provide the information otherwise required under this item. Item 4. Controls and Procedures Evaluation of Disclosure Controls and Procedures Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information 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 June 30, 2026. Changes in Internal Control over Financial Reporting There were no changes in our internal control over financial reporting that occurred during the fiscal quarter of 2026 covered by this Quarterly Report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. ​ 23 Table of Contents PART II - OTHER INFORMATION Item 1.
