NOTES TO THE CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) NOTE 1 — ORGANIZATION AND BUSINESS OPERATIONS Indigo Acquisition Corp. (the “Company”) is a Cayman Islands exempted company formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization, or similar business combination with one or more businesses (a “Business Combination”). The Company is not limited to any industry or geographic region but intends to pursue a Business Combination with a target that can benefit from the expertise and capabilities of the Company’s management team. As of September 30, 2025, the Company had not commenced any operations. All activity for the period from June 7, 2024 (inception) through September 30, 2025 relates to the Company’s formation, the initial public offering (“Initial Public Offering”), which is described below, and subsequent to the Initial Public Offering, identifying a target company for a Business Combination. The Company will not generate any operating revenues until after the completion of an initial 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 Company’s sponsor is Indigo Sponsor Group, LLC (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on June 30, 2025. On July 2, 2025, the Company consummated the Initial Public Offering of 10,000,000 units (the “Units” and, with respect to the ordinary shares included in the Units sold, the “Public Shares”) at $ 10.00 per Unit, which is discussed in Note 3, generating gross proceeds of $ 100,000,000 . Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of an aggregate of 350,000 Units (the “Private Placement Units”) to the Sponsor and EarlyBirdCapital, Inc., the representative of the underwriters in the Initial Public Offering (“EBC”), and their designees, at a price of $ 10.00 per Private Placement Unit, generating gross proceeds of $ 3,500,000 . Of the 350,000 Private Placement Units, the Sponsor and it designees purchased 225,000 Private Placement Units and EBC purchased 125,000 Private Placement Units. On July 11, 2025, the Company consummated the closing of an additional 1,500,000 Units sold pursuant to the underwriters’ over-allotment option, generating gross proceeds of $ 15,000,000 . Simultaneously with the consummation of the over-allotment option on July 11, 2025, the Company also consummated the sale of an additional 30,000 Private Placement Units to the Sponsor and EBC ( 19,286 to the Sponsor and 10,714 to EBC) at a price of $ 10.00 per Private Placement Unit, generating gross proceeds of $ 300,000 . Transaction costs amounted to $ 6,741,773 , consisting of $ 2,300,000 of cash underwriting fee, $ 4,025,000 of deferred underwriting fee, and $ 416,773 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 Units, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. Pursuant to applicable stock exchange listing rules, the Company’s initial Business Combination must be with one or more businesses or assets with a fair market value equal to at least 80 % of the assets held in the Trust Account (as defined below) (excluding the amount of deferred underwriting commissions and taxes payable on the income earned on the Trust Account). The Company intends to 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. Upon the closing of the Initial Public Offering and the over-allotment option, an aggregate amount of $ 115,000,000 ($ 10.00 per Unit) from the net proceeds of the sale of the Units and Private Placement Units were held in a trust account (the “Trust Account as cash and subsequently invested in a Money Market Mutual Fund. The Company can hold the funds the Trust Account in demand deposit or cash accounts or invest such proceeds only in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or in any open-ended investment company that holds itself out as a money market fund investing solely in U.S. Treasuries and meeting certain conditions under Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of (i) the completion of a Business Combination and (ii) the distribution of the funds in the Trust Account to the Company’s shareholders, as described below. The Company will provide the holders of the outstanding Public Shares (the “Public Shareholders”) with the opportunity to redeem all or a portion of their Public Shares either (i) in connection with a shareholder meeting called to approve the Business Combination or (ii) by means of a tender offer in connection with the Business Combination. 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 in its sole discretion subject to requirements of corporate law. The Public Shareholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially anticipated to be $ 10.00 per Public Share, plus any pro rata interest then in the Trust Account, net of taxes payable). The Public 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 the Accounting Standards Codification (“ASC”) Topic 480 “ Distinguishing Liabilities from Equity .” 5 INDIGO ACQUISITION CORP. NOTES TO THE CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) If the Company seeks shareholder approval of the Business Combination, the Company will proceed with a Business Combination only if the Company receives an ordinary resolution under Cayman Islands law approving a Business Combination, which requires the affirmative vote of a majority of the shareholders who attend and vote at a general meeting of the Company, or such other vote as required by law or stock exchange rule. If a shareholder vote is not required and the Company does not decide to hold a shareholder vote for business or other legal 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 (the “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), its Private Shares (as defined in Note 4) and, subject to applicable securities laws, any Public Shares purchased after the Initial Public Offering (including in open market and privately negotiated transactions) in favor of approving a Business Combination. Additionally, each Public Shareholder may elect to redeem their 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 the Business Combination and the Company does not conduct redemptions pursuant to the tender offer rules, 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 and EBC and their designees have agreed (a) to waive their redemption rights with respect to any Founder Shares, EBC Founder Shares (as defined in Note 4) and Private Shares held by them in connection with the completion of a Business Combination, (b) to waive their redemption rights with respect to their Founder Shares, EBC Founder Shares and Private Shares in connection with a shareholder vote to approve an amendment to the amended and restated memorandum and articles of association to (1) delay or modify the substance or timing of the obligation to provide for the redemption of the public shares in connection with an initial Business Combination or to redeem 100 % of the public shares if the Company does not complete the initial Business Combination within 21 months from the closing of the Initial Public Offering or (2) with respect to any other provisions relating to shareholders’ rights or pre-initial Business Combination activity, and (c) to waive their rights to liquidating distributions from the Trust Account with respect to any Founder Shares, EBC Founder Shares and Private Shares held by them if the Company fails to complete the initial Business Combination within 21 months from the closing of the Initial Public Offering or such later date as may be approved by the Company’s shareholders. The Company has until 21 months from the closing of the Initial Public Offering to consummate a Business Combination (the “Combination Period”). If the Company has not completed a Business Combination within the Combination Period and the Combination Period is not extended by shareholders pursuant to an amendment to the Company’s amended and restated articles of association, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem 100 % of 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 and not previously released to the Company to pay its taxes, if any (less $ 100,000 to pay liquidation and dissolution expenses), divided by the number of then issued and outstanding Public Shares, which redemption will completely extinguish the rights of the Public Shareholders as shareholders (including the right to receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining Public Shareholders and its Board of Directors, liquidate and dissolve, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. In order to protect the amounts held in the Trust Account, the Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party (other than the Company’s independent registered public accounting firm) for services rendered or products sold to the Company, or 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 the lesser of (1) $ 10.00 per Public Share and (2) 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 Public Share, due to reductions in the value of trust assets, in each case net of the interest that may be withdrawn to pay taxes. This liability will not apply to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and as to any claims by the Company’s auditors or 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”). 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 registered public accounting firm), 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 INDIGO ACQUISITION CORP. NOTES TO THE CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) Liquidity and Going concern As of September 30, 2025, the Company had $ 717,051 in its operating bank account and working capital surplus of $ 780,033 . The Company initially has until April 2, 2027 to consummate the initial Business Combination (assume no extensions). If the Company does not complete a Business Combination, the Company will trigger an automatic winding up, dissolution and liquidation pursuant to the terms of the Amended and Restated Memorandum and Articles of Association. Notwithstanding management’s belief that the Company would have sufficient funds to execute its business strategy, there is a possibility that the business combination might not happen within the 24-month period from the date of the Initial Public Offering. In connection with the Company’s assessment of going concern considerations in accordance with ASC 205-40, “Going Concern”, as of September 30, 2025, the Company may need to raise additional capital through loans or additional investments from its Sponsor, shareholders, officers, directors, or third parties. The Company’s officers, directors and Sponsor may, but are not obligated to, loan the Company funds, from time to time or at any time, in whatever amount they deem reasonable in their sole discretion, to meet the Company’s working capital needs. Accordingly, the Company may not be able to obtain additional financing. If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could include, but not necessarily be limited to, curtailing operations, suspending the pursuit of a potential transaction, and reducing overhead expenses. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all. Management plans to address this uncertainty through a Business Combination. If a Business Combination is not consummated by the end of the Combination Period, currently April 2, 2027, there will be mandatory liquidation and subsequent dissolution of the Company. Management has determined that the liquidity condition raises substantial doubt about the Company’s ability to continue as a going concern. 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 intends to complete the initial Business Combination before the end of the Combination Period. However, there can be no assurance that the Company will be able to consummate any Business Combination by the end of the Combination Period. 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 (“US 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 (the “SEC”). Certain information or footnote disclosures normally included in financial statements prepared in accordance with US 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 prospectus for its Initial Public Offering as filed with the SEC on July 1, 2025, as well as the Company’s Current Report on Form 8-K, as filed with the SEC on July 10, 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 fiscal year ending December 31, 2025 or for any future periods. 7 INDIGO ACQUISITION CORP. NOTES TO THE 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 of 1933, as amended (the “Securities Act”), as modified by the Jumpstart Our Business Startups Act of 2012, as amended (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 independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Use of Estimates The preparation of the unaudited condensed financial statements in conformity with US 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 and the reported amounts of revenues and expenses during the reporting period. 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 significantly from those estimates. 8 INDIGO ACQUISITION CORP. NOTES TO THE CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (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 has $ 717,051 and $0 in cash as of September 30, 2025 and December 31, 2024, respectively, and no cash equivalents as of September 30, 2025 and December 31, 2024. Marketable Securities Held in Trust Account As of September 30, 2025 and December 31, 2024, the assets held in the Trust Account, amounting to $ 116,165,212 and $ 0 , were held in a Money Market Mutual Fund. 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 federally insured limits. The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. Offering Costs Associated with the Initial Public Offering The Company complies with the requirements of the ASC 340-10-S99 and SEC Staff Accounting Bulletin (“SAB”) Topic 5A — “Expenses of Offering”. Offering costs consist of underwriting, legal, and other expenses incurred through the balance sheet date that are directly related to the Initial Public Offering and were charged to shareholders’ deficit upon the completion of the Initial Public Offering. Income Taxes The Company follows the asset and liability method of accounting for income taxes under ASC 740, “ Income Taxes .” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. ASC 740 prescribes a recognition threshold and a measurement attribute for the 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. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of September 30, 2025 (unaudited) 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 may be subject to potential examination by foreign taxing authorities in the area of income taxes. These potential examinations may include questioning the timing and amount of deductions, the nexus of income among various tax jurisdictions and compliance with foreign tax laws. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months. The Company is considered to be 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. In accordance with Cayman income tax regulations, income taxes are not levied on the Company. Consequently, income taxes are not reflected in the Company’s financial statements. Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC 820, “ Fair Value Measurement ,” approximates the carrying amounts represented in the balance sheet, primarily due to their short-term nature. 9 INDIGO ACQUISITION CORP. NOTES TO THE CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) 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, if there is a shareholder vote (A) to modify the substance or timing of the Company’s obligation to allow redemption in connection with a Business Combination or to redeem 100 % of the Public Shares if the Company does not complete an initial business combination within the completion window or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial Business Combination activity, or if there is a shareholder vote or tender offer in connection with the Company’s initial Business Combination. In accordance with ASC 480-10-S99, the Company classifies Public Shares subject to redemption outside of permanent equity as the redemption provisions are not solely within the control of the Company. The Company recognizes changes in redemption value immediately as they occur and will adjust the carrying value of redeemable shares to equal the redemption value at the end of each reporting period. Immediately upon the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption value. The change in the carrying value of redeemable shares will result in charges against additional paid-in capital (to the extent available) and accumulated deficit. Accordingly, as of September 30, 2025 the ordinary shares subject to possible redemption are presented at redemption value as temporary equity, outside of the shareholders’ deficit section of the Company’s balance sheet. As of September 30, 2025, the ordinary shares subject to possible redemption reflected in the balance sheet are reconciled in the following table: Gross proceeds $ 115,000,000 Less: Proceeds allocated to Public Rights ( 2,530,000 ) Proceeds allocated to over-allotment ( 127,802 ) Ordinary shares issuance cost ( 6,572,939 ) Plus: Accretion of carrying value to redemption value 10,395,953 Ordinary Shares subject to possible redemption, September 30, 2025 $ 116,165,212 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 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. 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 statement of operations. Share Rights The Company accounts for the public and private placement rights issued in connection with the Initial Public Offering and the private placement in accordance with the guidance contained in FASB ASC Topic 815, “Derivatives and Hedging”. Accordingly, the Company evaluated and classified the rights under equity treatment at their assigned values. Net (Loss) Income per Share The Company complies with accounting and disclosure requirements of ASC 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as ordinary shares subject to possible redemption and non-redeemable ordinary shares. Income and losses are shared pro rata between the two classes of shares. Net income (loss) per ordinary share is calculated by dividing the net income (loss) by the weighted average ordinary shares outstanding for the respective period. Diluted net income (loss) per share attributable to ordinary shareholders adjusts the basic net income (loss) per share attributable to ordinary shareholders and the weighted-average ordinary shares outstanding for the potentially dilutive impact of private placement. With respect to the accretion of ordinary shares subject to possible redemption and consistent with ASC Topic 480-10-S99-3A, the Company treated accretion in the same manner as a dividend paid to the shareholders in the calculation of the net income (loss) per ordinary share. 10 INDIGO ACQUISITION CORP. NOTES TO THE CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) The following table reflects the calculation of basic and diluted net income per ordinary share: For the Three Months Ended September 30, 2025 2024 Non- Non- Redeemable redeemable Redeemable redeemable Basic net income per ordinary share Numerator: Allocation of net income $ 786,577 $ 226,621 $ — $ — Denominator: Basic weighted average ordinary shares outstanding 11,103,261 3,198,967 — 2,500,000 Basic net income per ordinary share $ 0.07 $ 0.07 $ — $ — For the Three Months Ended September 30, 2025 2024 Non- Non- Redeemable redeemable Redeemable redeemable Diluted net income per ordinary share Numerator: Allocation of net income $ 784,119 $ 229,079 $ — $ — Denominator: Diluted weighted average ordinary shares outstanding 11,103,261 3,243,804 — 2,500,000 Diluted net income per ordinary share $ 0.07 $ 0.07 $ — $ — For the Nine Months Ended September 30, 2025 For the Period from June 7, 2024 (Inception) through September 30, 2024 Non- Non- Redeemable redeemable Redeemable redeemable Basic net (loss)income per ordinary share Numerator: Allocation of net (loss) income $ 471,868 $ 343,821 $ — $ ( 16,532 ) Denominator: Basic weighted average ordinary shares outstanding 3,755,515 2,736,415 — 2,500,000 Basic net (loss) income per ordinary share $ 0.13 $ 0.13 $ — $ ( 0.01 ) For the Nine Months Ended September 30, 2025 For the Period from June 7, 2024 (Inception) through September 30, 2024 Non- Non- Redeemable redeemable Redeemable redeemable Diluted net (loss)income per ordinary share Numerator: Allocation of net (loss) income $ 453,474 $ 362,215 $ — $ ( 16,532 ) Denominator: Diluted weighted average ordinary shares outstanding 3,755,515 2,999,743 — 2,500,000 Diluted net (loss) income per ordinary share $ 0.12 $ 0.12 $ — $ ( 0.01 ) 11 INDIGO ACQUISITION CORP. NOTES TO THE CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) Recent Accounting Standards In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures”. The amendments in this ASU require disclosures, on an annual and interim basis, of significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”), as well as the aggregate amount of other segment items included in the reported measure of segment profit or loss. The ASU requires that a public entity disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. Public entities will be required to provide all annual disclosures currently required by Topic 280 in interim periods, and entities with a single reportable segment are required to provide all the disclosures required by the amendments in this ASU and existing segment disclosures in Topic 280. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company adopted ASU 2023-07 on June 7, 2024, the date of incorporation. On July 4, 2025, President Trump signed into law the One Big Beautiful Bill Act (“OBBA”). ASC 740, “Income Taxes”, requires the effects of changes in tax laws to be recognized in the period in which the legislation is enacted. The Company is currently evaluating the impact of the new law. However, none of the tax provisions are expected to have a significant impact on the Company’s financial statements. 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. NOTE 3 — INITIAL PUBLIC OFFERING Pursuant to the Initial Public Offering on July 2, 2025, the Company sold 10,000,000 Units at a price of $ 10.00 per Unit for a total of $ 100,000,000 . On July 11, 2025, the Company consummated the closing of an additional 1,500,000 Units sold pursuant to the underwriters’ over-allotment option, generating gross proceeds of $ 15,000,000 . Each Unit consists of one Public Share and one right (“Public Right”), with each Public Right entitling the holder to receive one-tenth of one ordinary share upon consummation of a Business Combination. NOTE 4 — PRIVATE PLACEMENTS Simultaneously with the closing of the Initial Public Offering, the Sponsor, EBC and their designees purchased an aggregate of 350,000 Private Placement Units at a price of $ 10.00 per Private Placement Unit for an aggregate purchase price of $ 3,500,000 . Of those 350,000 Private Placement Units, the Sponsor and its designees purchased 225,000 Private Placement Units and EBC purchased 125,000 Private Placement Units. Simultaneously with the closing of the over-allotment option on July 11, 2025, the Company consummated the sale of an additional 30,000 Private Placement Units to the Sponsor and EBC at a price of $ 10.00 per Unit, generating gross proceeds of $ 300,000 . Of those 30,000 Private Placement Units, the Sponsor and its designees purchased 19,286 Private Placement Units and EBC purchased 10,714 Private Placement Units. Each Private Placement Unit consists of one ordinary share (each, a “Private Share”), and one right (each, a “Private Right”), with each Private Right entitling the holder to receive one-tenth of one ordinary share upon consummation of a Business Combination. The proceeds from the sale of the Private Placement Units was 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 held in the Trust Account will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law). The Private Placement Units and underlying securities will not be transferable, assignable, or salable until the completion of a Business Combination, subject to certain exceptions. 12 INDIGO ACQUISITION CORP. NOTES TO THE CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) Certain investors (the “non-managing investors”) committed, pursuant to written agreements, and purchased, indirectly through the purchase of non-managing membership interests in the Sponsor, an aggregate of 195,112 Private Placement Units out of the 210,000 Private Placement Units purchased by the Sponsor. In exchange for each non-managing sponsor investor purchasing the Private Placement Units allocated to it in connection with the closing of the Initial Public Offering, the Sponsor issued additional membership interests at a nominal purchase price to the non-managing investors reflecting interests in an aggregate of approximately 1.5 million Founder Shares. The agreement with the non-managing investors was entered into directly with the Sponsor entity and it makes reference to the Private Placement Units and Founder Shares of the Company. The interests and units associated in the agreement are supported on one for one basis with the Company’s underlying Private Placement Units and Founder Shares. The fact that the Sponsor provided the non-managing members with Founder Shares for their participation in the transaction is considered an inducement and falls under SAB Topic 5A. As such, the Company has obtained a valuation of the Founder Shares, as of the Initial Public Offering date to account for the charge of such transfer of interests to the non-managing members. The valuation determined the fair value of the Founder Shares to be $ 1.96 per share as of the close of the Initial Public Offering, on July 2, 2025. Since the cost of these interest allocations to the non-managing members is considered an offering cost, the Company recorded the fair value of this transaction into equity at the Initial Public Offering date calculated as 1,459,862 interests in Founder Shares allocated to non-managing members at a fair value of $ 1.96 ,or $ 2,861,330 . The third-party valuation firm valued the Founder Shares as of July 2, 2025. The likelihood of completing the Business Combination was assumed to be 23.0 %; the implied ordinary share price was $ 9.78 ; and a discount for lack of marketability was 13 %. The transferred interests to the non-managing members are classified as Level 3 at the measurement date due to the use of unobservable inputs including the probability of a business combination, and other risk factors. NOTE 5 — RELATED PARTIES Founder Shares On June 7, 2024, the Company issued 2,875,000 ordinary shares to EBC Holdings, Inc. (“EBC Holdings”) for an aggregate purchase price of $ 5,000 , or approximately $ 0.0017 . Up to 375,000 of such ordinary shares were subject to forfeiture to the extent that the underwriters’ over-allotment was not exercised in full. On July 11, 2025, the underwriters fully exercised their over-allotment option resulting in such 375,000 Founder Shares no longer being subject to forfeiture. On March 7, 2025, EBC Holdings transferred 2,090,000 of its shares to the Sponsor for a purchase price of approximately $ 0.0017 per share and an aggregate purchase price of $ 3,636 . Additionally, on March 7, 2025, EBC Holdings transferred 75,000 of such shares to three director nominees ( 25,000 shares each) for a purchase price of $ 0.0017 per share and an aggregate purchase price of $ 43 each (such shares, together with the 2,090,000 shares transferred to the Sponsor, the “Founder Shares,” and the 710,000 shares retained by EBC Holdings, the “EBC Founder Shares”). The sale of the Founders Shares to the Company’s director 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 transferred to the Company’s director nominees was $ 108,750 , or $ 1.45 per share. The Founders Shares were transferred to the director nominees on March 7, 2025 without any agreements or limitations to performance conditions. Compensation expense related to the Founders Shares is recognized immediately at the time of transfer as stock compensation in the statement of operations. The Company established the initial fair value for the director nominees’ Founder Shares on March 7, 2025, the date of the issuance, through a third-party valuation which takes into consideration the probability of completion of the Initial Public Offering, an implied probability of the completion of a Business Combination and a Discount for Lack of Marketability calculation. The transferred Founder Shares are classified as Level 3 at the measurement date due to the use of unobservable inputs including the probability of a business combination, the probability of the Initial Public Offering, and other risk factors. On June 30, 2025, the Sponsor transferred 105,000 ordinary shares to an independent third party joining the Sponsor group and EBC transferred 190,379 ordinary shares to EBCH Indigo LLC. The Sponsor has agreed, subject to limited exceptions, not to transfer, assign or sell any of the Founder Shares until the earlier to occur of: (A) six months after the completion of the initial Business Combination and (B) the date on which the Company completes a liquidation, merger, share exchange, reorganization or other similar transaction after the initial Business Combination that results in all public shareholders having the right to exchange their ordinary shares for cash, securities or other property; provided that 50 % of the Founder Shares shall be released earlier from the foregoing lockup provisions if the closing price of the Company’ ordinary shares equals or exceeds $ 12.00 per share (as adjusted for share subdivisions, share capitalizations, reorganizations, recapitalizations and the like) for any 10 trading days within any 20 -trading day period. 13 INDIGO ACQUISITION CORP. NOTES TO THE CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) Promissory Note — Related Party On March 25, 2025, April 17, 2025 and June 13, 2025, the Sponsor and EBC entered agreements (collectively, the “Promissory Note”) to loan the Company an aggregate of $ 95,000 , $ 70,000 and $ 10,000 , respectively, to be used for a portion of the expenses of the Initial Public Offering. The loans were non-interest bearing, unsecured and due at the earlier of December 31, 2025 or the closing of the Initial Public Offering. As of September 30, 2025 and December 31, 2024, there were no outstanding balance, respectively, outstanding under the Promissory Note. On July 2, 2025, the Company repaid $ 174,000 of the outstanding balance of the Promissory Note and on July 7, 2025, the Company repaid the remaining $ 1,000 to the Sponsor. Borrowings under the Promissory Note are no longer available. Administration Fee Commencing on the effective date of the Initial Public Offering, June 30, 2025, the Company entered into an agreement with the Sponsor to pay an aggregate of $ 10,000 per month for office space, administrative and support services. These monthly fees will cease upon the completion of the initial Business Combination or the liquidation of the Company. For the three and nine months ended September 30, 2025, the Company incurred and paid $ 30,000 for these services. Related Party Loans In order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor or the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required. If the Company completes a Business Combination, the Company would repay the Working Capital Loans. In the event that a Business Combination does not close, the Company may use a portion of the working capital held outside the Trust Account to repay the Working Capital Loans but no proceeds from the Trust Account would be used to repay the Working Capital Loans. Up to $ 1,500,000 of such Working Capital Loans may be convertible into private placement units of the post Business Combination entity at a price of $ 10.00 per unit at the option of the lender. The units would be identical to the Private Placement Units. As of September 30, 2025 and December 31, 2024, no such Working Capital Loans were outstanding. NOTE 6 — COMMITMENTS AND CONTINGENCIES Registration Rights The holders of the Founder Shares, EBC Founder Shares, Private Placement Units and any units that may be issued upon conversion of working capital loans (and all underlying securities) are entitled to registration rights pursuant to a registration rights agreement signed on the effective date of Initial Public Offering requiring the Company to register such securities for resale. 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 “piggy-back” registration rights with respect to registration statements filed subsequent to 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. In compliance with FINRA Rule 5110(f)(2)(G), the registration rights granted to EBC and EBC Holdings are limited to demand and “piggyback” rights for periods of five and seven years, respectively, from the effective date of the Initial Public Offering and EBC and EBC Holdings may only exercise demand rights on one occasion. The Company will bear the expenses incurred in connection with the filing of any such registration statements. Underwriting Agreement The underwriters were granted a 45 -day option from June 30, 2025, the effective date of the Initial Public Offering, to purchase up to 1,500,000 additional Units to cover over-allotments at the Initial Public Offering price less the underwriting discounts and commissions. The over-allotment option was exercised in full by the underwriters on July 8, 2025 and consummated on July 11, 2025. The underwriters are entitled to a cash underwriting discount of $ 0.20 per Unit, or $ 2,300,000 in the aggregate, which was paid upon the closing of the Initial Public Offering. Additionally, the underwriters are entitled to a deferred underwriting discount equal to 3.5 % of the gross proceeds, or an aggregate of $ 4,025,000 , of the Initial Public Offering. 14 INDIGO ACQUISITION CORP. NOTES TO THE CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) NOTE 7 — SHAREHOLDERS’ DEFICIT Ordinary Shares — The Company is authorized to issue 200,000,000 ordinary shares with a par value of $ 0.0001 per share. Holders of ordinary shares are entitled to one vote for each share. As of September 30, 2025 and December 31, 2024, there were 3,255,000 and 2,875,000 respectively ordinary shares issued and outstanding, of which an aggregate of up to 375,000 ordinary shares were subject to forfeiture to the extent that the underwriters’ over-allotment option was not exercised in full or in part so that the number of Founder Shares and EBC Founder Shares would equal, in the aggregate, 20 % of the Company’s issued and outstanding ordinary shares after the Initial Public Offering (excluding Private Shares). On July 8, 2025, the underwriters fully exercised their over-allotment option and the sale of units pursuant thereto was consummated on July 11, 2025 resulting in 375,000 Founder Shares no longer being subject to forfeiture. Rights — Except in cases where the Company is not the surviving company in a business combination, each holder of a right will automatically receive one-tenth (1/10) of one ordinary share upon consummation of the initial Business Combination. The Company will not issue fractional shares in connection with an exchange of rights. Fractional shares will either be rounded down to the nearest whole share or otherwise addressed in accordance with the applicable provisions of Cayman law. In the event the Company is not the surviving company upon completion of the initial business combination, each holder of a right will be required to affirmatively convert his, her or its rights in order to receive the one-tenth (1/10) of one ordinary share underlying each right upon consummation of the Business Combination. If the Company is unable to complete the initial Business Combination within the required time period and the Company will redeem the public shares for the funds held in the Trust Account, holders of rights will not receive any of such funds for their rights and the rights will expire worthless. 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 our assessment of the assumptions that market participants would use in pricing the asset or liability. The following table presents information about the Company’s assets that are measured at fair value on as of September 30, 2025, and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value : Description Level September 30, 2025 Assets: Marketable securities held in Trust account 1 $ 116,165,212 15 INDIGO ACQUISITION CORP. NOTES TO THE CONDENSED FINANCIAL STATEMENTS SEPTEMBER 30, 2025 (UNAUDITED) NOTE 9 — SEGMENT INFORMATION 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 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 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. 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 statement of operations as net income or loss. When evaluating the Company’s performance and making key decisions regarding resource allocation the CODM reviews several key metrics, which include the following: 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 7, 2024 (inception) through September 30, 2024 Formation and operating costs $ 152,601 $ — $ 241,360 $ 16,532 Dividend earn on marketable securities held in Trust Account $ 1,165,212 $ — $ 1,165,212 $ — Formation and operating costs 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 formation and operating costs to manage, maintain and enforce all contractual agreements to ensure costs are aligned with all agreements and budget. Formation and operating costs are the significant segment expenses provided to the CODM on a regular basis. NOTE 10 — SUBSEQUENT EVENTS The Company evaluated subsequent events and transactions that occurred after the balance sheet date and through the date that the unaudited 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 financial statements. 16 Item 2.

Overview We are a blank check company incorporated in the Cayman Islands on June 7, 2024, formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization, or 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 Units, our shares, debt or a combination of cash, shares and debt. We expect to incur significant costs in the pursuit of our acquisition plans. We cannot assure you that our plans to complete a Business Combination will be successful. Results of Operations We have neither engaged in any operations nor generated any revenues to date. Our only activities from June 7, 2024 (inception) through September 30, 2025 were organizational activities, those necessary to prepare for the Initial Public Offering, described below, and subsequent to the 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 Business Combination. We generate non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering and the sale of the Private Placement Units 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 September 30, 2025, we had a net income of $1,013,198, which consists of formation and operating costs of $152,601, offset by other income from change on overallotment liability of $587 and interest income of $1,165,212. For the nine months ended September 30, 2025, we had a net income of $815,689, which consists of share based compensation expense of $108,750 and formation and operating costs of $241,360, offset by interest income of $1,165,212 and by other income from change on overallotment liability of $587. For the three months ended September 30, 2024, we had no income or loss. For the period from June 7, 2024 (inception) through September 30, 2024, we had a net loss of $16,532, which consists of formation and operating costs. 17 Liquidity and Going concern On July 2, 2025, we consummated the Initial Public Offering of 10,000,000 Units at $10.00 per Unit, generating gross proceeds of $100,000,000. Simultaneously with the closing of the Initial Public Offering, we consummated the sale of an aggregate of 350,000 Private Placement Units to the Sponsor and EBC and their designees, at a price of $10.00 per Unit, generating gross proceeds of $3,500,000. Of the 350,000 Private Placement Units, the Sponsor and its designees purchased 225,000 Private Placement Units and EBC purchased 125,000 Private Placement Units. On July 11, 2025, we consummated the closing of an additional 1,500,000 Units sold pursuant to the underwriters’ over-allotment option, generating gross proceeds of $15,000,000. Simultaneously with the closing of the over-allotment option on July 11, 2025, we also consummated the sale of an additional 30,000 Private Placement Units, generating total proceeds of $300,000. Of those 30,000 Private Placement Units, the Sponsor and its designees purchased 19,286 Private Placement Units and EBC purchased 10,714 Private Placement Units. Following the closing of the Initial Public Offering, the Private Placement and the over-allotment option, a total of $115,000,000 was placed in the Trust Account. We incurred $6,741,773, consisting of $2,300,000 of cash underwriting fee, $4,025,000 of deferred underwriting fee, and $416,773 of other offering costs. For the nine months ended September 30, 2025, cash used in operating activities was $425,844. Net income of $815,689 was affected by compensation expense to directors of $108,750, Interest earned on marketable securities held in Trust Account of $1,165,212, and Change in FV of Overallotment liability of $587. Changes in operating assets and liabilities used $184,484 of cash for operating activities. For the period from June 7, 2024 (inception) through September 30, 2024, cash used in operating activities was $10,000. Net loss of $16,532 was affected by payment of formation costs through issuance of ordinary shares of $5,000. Changes in operating assets and liabilities used $1,532 of cash for operating activities. As of September 30, 2025, we had marketable securities held in the Trust Account of $116,165,212 (including approximately $1,165,212 of interest income) consisting of U.S. Treasury Bills with a maturity of 185 days or less. We may withdraw interest from the Trust Account to pay taxes, if any. We intend to use substantially all of the funds held in the Trust Account, including any amounts representing interest earned on the Trust Account (less income taxes payable), to complete our Business Combination. To the extent that our share capital or debt is used, in whole or in part, as consideration to complete our Business Combination, the remaining proceeds held in the Trust Account will be used as working capital to finance the operations of the target business or businesses, make other acquisitions and pursue our growth strategies. As of September 30, 2025, we had cash of $717,051. 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 units of the post Business Combination entity at a price of $10.00 per unit at the option of the lender. The units and the underlying securities would be identical to the Private Placement Units. We plan to address this uncertainty through a Business Combination. If a Business Combination is not consummated by the end of the Combination Period, currently April 2, 2027, there will be mandatory liquidation and subsequent dissolution of the Company. We have determined that the liquidity condition raises substantial doubt about the Company’s ability to continue as a going concern. 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 intends to complete the initial Business Combination before the end of the Combination Period. However, there can be no assurance that the Company will be able to consummate any Business Combination by the end of the Combination Period. 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. 18 Contractual obligations We do not have any long-term debt, capital lease obligations, operating lease obligations or long-term liabilities, other than an agreement pay an aggregate of $10,000 per month for office space, administrative and support services. We began incurring these fees on July 1, 2025 and will continue to incur these fees monthly until the earlier of the completion of the Business Combination and our liquidation. The underwriters are entitled to a deferred underwriting discount equal to 3.5% of the gross proceeds, or an aggregate of $4,025,000, of the Initial Public Offering. Critical Accounting Estimates The preparation of unaudited financial statements in conformity with accounting principles generally accepted in the United States of America requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the unaudited 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 financial statements, which Management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, actual results could materially differ from those estimates. As of September 30, 2025, we did not have any critical accounting estimates to be disclosed. 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 that occurred during the fiscal quarter of 2025 covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. 19 PART II - OTHER INFORMATION Item 2.
