ORGANIZATION AND BUSINESS OPERATIONS	NOTE 1 — ORGANIZATION AND BUSINESS OPERATIONS Organizational and General Cayson Acquisition Corp (the “Company”) was incorporated in the Cayman Islands on May 27, 2024. The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, or similar business with one or more businesses (the “Business Combination”). The Company is not limited to a particular industry or sector for purposes of consummating a Business Combination. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. The Company’s sponsors are Yawei Cao and Cayson Holding LP, a Delaware limited partnership (the “Sponsors”). As of June 30, 2026, the Company had not commenced any operations. All activity for the period from May 27, 2024 (inception) through June 30, 2026 relates to the Company’s formation and the initial public offering (“Initial Public Offering” or “IPO”), which is described below, and identifying a target company for our initial Business Combination. The Company will not generate any operating revenues until after the completion of an initial Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end. The registration statement for the Company’s IPO (the “Registration Statement”) was declared effective on September 19, 2024. On September 23, 2024, the Company consummated the IPO of 6,000,000 units, (“Units” and, with respect to the ordinary shares included in the Units being offered, the “Public Shares”), generating gross proceeds of $60,000,000, which is described in Note 3, and the sale of 230,000 Units (the “Private Placement Units”) at a price of $10.00 per Private Placement Unit in a private placement to the Sponsors, that was closed simultaneously with the IPO. Additionally, on October 15, 2024, the underwriters’ over-allotment option expired and the Sponsors forfeited an aggregate of 225,000 founder shares. Transaction costs amounted to $3,722,528 (net of $300,000 underwriters cash reimbursement of deferred offering cost), consisting of $1,200,000 of cash underwriting fees, $2,100,000 of deferred underwriting commission and $422,528 (net of $300,000 underwriters cash reimbursement of deferred offering cost) of other offering costs. These costs were charged to additional paid-in capital or accumulated deficit to the extent additional paid-in capital is fully depleted upon completion of the IPO. The Company originally had up to 21 months to consummate an initial Business Combination, if the Company extended the time to complete a Business Combination as provided in the Registration Statement (the “Combination Period”). The Combination Period was extended in December 2025 as indicated below. If the Company does not complete an initial Business Combination within the Combination Period and such time period is not further extended by the Company’s shareholders, 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 on the funds held in the trust account and not previously released to us to pay our taxes (less up to $100,000 of interest to pay liquidation and dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and our board of directors, dissolve and liquidate, subject in each case to our obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. *The Trust Account* On September 23, 2024, a total of $60,000,000 of the net proceeds from the Initial Public Offering, including proceeds of the sale of the Private Placement Units, was deposited in a trust account (the “Trust Account”) and will be invested 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. *Proposed Business Combination* The Company has entered into an Agreement and Plan of Merger (the “Merger Agreement”), dated as of July 11, 2025 and amended on September 11, 2025, April 14, 2026 and June 24, 2026, by and among the Company, Mango Financial Group Limited, a Cayman Islands exempted company ( “Mango Group” or “MFG”), North Water Investment Group Holdings Limited (“North Water”), the parent company of Mango Financial Limited (“Mango Financial”), and Mango Temp Limited, a Cayman Islands exempted company and a wholly-owned subsidiary of Mango Group (“Merger Sub”). Each of the foregoing parties is referred to herein as a “Party” and collectively as the “Parties”. Pursuant to the Agreement, upon the closing of the transactions contemplated by the Merger Agreement, the Company will become a wholly owned subsidiary of Mango Group, which will become the parent company of Mango Financial. *Extension of Time to Consummate Business Combination* Effective as of September 17, 2025, Cayson Holding LP, one of the Company’s Sponsors, and Mango Financial loaned the Company an aggregate of $600,000. Such funds were deposited into escrow account managed by the Company’s trustee, Continental. On October 10, 2025, the Company’s trustee, deposited $600,000 into the Trust Account. Such funds are subject to possible redemption by the Company’s public shareholders in accordance with the terms of the Trust Account, and were used to extend the period of time the Company has to consummate a Business Combination from September 23, 2025 to December 23, 2025. Effective as of December 17, 2025, Mango Financial loaned the Company an aggregate of $600,000. On December 23, 2025, such funds were deposited into the Trust Account. Such funds are subject to possible redemption by the Company’s public shareholders in accordance with the terms of the Trust Account, and were used to extend the period of time the Company has to consummate a Business Combination from December 23, 2025 to March 23, 2026. On March 18, 2026, the Company held an extraordinary general meeting virtually, solely with respect to voting on (i) the proposal to extend the date by which the Company must complete its initial business combination on a monthly basis, up to twelve (12) months (or until March 23, 2027) (the “Extended Date”) (the “2026 Extension Amendment Proposal”), (ii) the proposal to remove the limitation that the Company shall not redeem public shares to the extent that such redemptions would cause the Company’s net tangible assets to be less than $5,000,001 (the “Redemption Limitation Proposal”), and (iii) the proposal to amend the Company’s investment management trust agreement, dated September 19, 2024, by and between the Company and the Trustee to allow the Company to extend the Termination Date up to twelve times from the Termination Date to March 23, 2027 with all twelve extensions comprised of one month each by providing five days’ advance notice to the Trustee and depositing into the Trust Account a payment of $125,000 per extension (the “Extension Payment”) until March 23, 2027. In connection with the vote to approve the 2026 Extension Amendment Proposal and the Redemption Limitation Proposal at the Extraordinary General Meeting on March 18, 2026, the holders of 2,541,908 Ordinary Shares properly exercised their rights to redeem their shares for cash at a redemption price of approximately $10.83 per share, for an aggregate redemption amount of approximately $27,536,647. Effective as of March 18, 2026, Mango Financial agreed to lend the Company an aggregate of $750,000. $625,000 of such amount has been loaned to the Company and the Company deposited such amounts into the trust account established by the Company in connection with its initial public offering pursuant to the Company’s Amended and Restated Memorandum and Articles of Association and trust agreement, as amended, governing the trust account in order to extend the time that the Company has to consummate an initial business combination (a “Business Combination”) as described below. The loans are evidenced by a promissory note (the “Note”) issued by the Company to Mango Financial. The Note bears no interest and is repayable in full upon consummation of a Business Combination. On each of March 19, 2026, April 22, 2026, May 21, 2026, June 23, 2026 and July 22, 2026 , $125,000 was deposited into the trust Account, extending in monthly increments the deadline from March 23, 2026 to August 23, 2026. *Going Concern Consideration* As of June 30, 2026, the Company had $54,485 in its operating bank account and a working capital deficit of $1,719,032. Further, the Company has incurred and expects to continue to incur significant costs in pursuit of its financing and acquisition plans in pursuit of a Business Combination. In connection with the Company’s assessment of going concern considerations in accordance with Financial Accounting Standard Board’s Accounting Standards Update (“ASU”) 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” management has determined that these conditions raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued. In addition, if the Company is unable to complete a Business Combination within the Combination Period, the Company’s board of directors would proceed to commence a voluntary liquidation and thereby a formal dissolution of the Company. There is no assurance that the Company’s plans to consummate a Business Combination will be successful within the Combination Period. As a result, management has determined that such additional condition also raises substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.
