The disclosures set forth under Item 2.03 are incorporated by reference.

**Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant**

Pursuant to the amended and restated memorandum and articles of association (the "**Charter**") of Eureka Acquisition Corp, a Cayman Islands exempted company (the "**Company**"), the Company had until February 3, 2026 to complete its initial business combination, however the Company may extend the period of time to consummate a business combination up to July 3, 2026, each by a one-month extension, subject to the deposit of $150,000 (the "**Monthly Extension Fee**") into the trust account of the Company (the "**Trust Account**").

On February 3, 2026, an aggregate of $150,000 of the Monthly Extension Fee was deposited into the Trust Account for the public shareholders, which enables the Company to extend the period of time it has to consummate its initial business combination by one month from February 3, 2026 to March 3, 2026 (the "**Extension**"). The payment of the Monthly Extension Fee was made by Hercules Capital Management Corp, the sponsor of the Company (the "**Sponsor**"). The Company issued an unsecured promissory note in the aggregate principal amount of $150,000 (the "**Extension Note**") dated February 4, 2026 to the Sponsor in connection with the payment of the Monthly Extension Fee.

The Extension Note bears no interest and is payable in full upon the earlier to occur of (i) the consummation of the Company's business combination or (ii) the date of expiry of the term of the Company (the "**Maturity Date**"). The following shall constitute an event of default: (i) a failure to pay the principal within five business days of the Maturity Date; (ii) the commencement of a voluntary or involuntary bankruptcy action, (iii) the breach of the Company's obligations thereunder; (iv) any cross defaults; (v) an enforcement proceedings against the Company; and (vi) any unlawfulness and invalidity in connection with the performance of the obligations thereunder, in which case the Extension Note may be accelerated.

The payee of the Extension Note, the Sponsor, has the right, but not the obligation, to convert the Extension Note, in whole or in part, respectively, into private units (the "**Units**") of the Company, each consisting of one Class A ordinary share, par value $0.0001 per share (the "**Class A Ordinary Share**") and one right to receive one-fifth (1/5) of one Class A Ordinary Share upon the consummation of a business combination, as described in the prospectus of the Company (File No: 333-277780), by providing the Company with written notice of the intention to convert at least two business days prior to the closing of the business combination. The number of Units to be received by the Sponsor in connection with such conversion shall be an amount determined by dividing (x) the sum of the outstanding principal amount payable to the Sponsor by (y) $10.00.

The issuance of the Extension Note was made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act of 1933, as amended.

A copy of the Extension Note is attached as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference. The foregoing description of the Extension Note does not purport to be complete and is subject to, and is qualified in its entirety by, the full text of the Extension Note.

**Item 3.02 Unregistered Sales of Equity Securities**

The information disclosed under Item 2.03 of this Current Report on Form 8-K is incorporated by reference into this Item 3.02 to the extent required herein. The Units (and the underlying securities) issuable upon conversion of the Note, if any, (1) may not, subject to certain limited exceptions, be transferable or salable by the Sponsor until the completion of the Company's initial business combination and (2) are entitled to registration rights.

Dated: February 4, 2026

New York, New York

**FOR VALUE RECEIVED**, Eureka Acquisition Corp(the "**Maker**" or the "**Company**") promises to pay to the order of Hercules Capital Management Corp, or its registered assignees or successors in interest (the **"Payee**"), the principal sum of USD ONE HUNDRED AND FIFTY THOUSAND ONLY (US$150,000.00), on the terms and conditions described below. All payments on this Note shall be made by wire transfer of immediately available funds to such account as the Payee may from time to time designate by written notice in accordance with the provisions of this note (the "**Note**").

1. **Principal.** The principal balance of this Note shall be payable by the Maker to the Payee upon the date on which
 the Maker consummates a business combination or merger with a qualified target company (as described
 in its Prospectus (as defined below)) (a "**Business Combination**") or the date of expiry
 of the term of the Maker, whichever is earlier (such date, the "**Maturity Date** ").
 The principal balance may be prepaid at any time prior to the Maturity Date without penalty. Under no
 circumstances shall any individual, including but not limited to any officer, director, employee or
 stockholder of the Maker, be obligated personally for any obligations or liabilities of the Maker hereunder.

2. **Conversion Rights**. The Payee has the right, but not the obligation, to convert this Note, in whole or in part,
 into private unit (the "**Units**") of the Maker, each consisting of one Class A ordinary
 share and one right to receive one-fifth (1/5) of one Class A ordinary share upon the consummation of
 a Business Combination, as described in the Prospectus of the Maker (File No. 333-277780) (the "**Prospectus** "),
 by providing the Maker with written notice of its intention to convert this Note at least two business
 days prior to the closing of a Business Combination. The number of Units to be received by the Payee
 in connection with such conversion shall be an amount determined by dividing (x) the sum of the outstanding
 principal amount payable to such Payee by (y) $10.00.

&nbsp;&nbsp;&nbsp;&nbsp;(a) **Fractional Units**. No fractional Units will be issued upon conversion of this Note. In lieu of any
 fractional Units to which Payee would otherwise be entitled, the Maker will pay to Payee
 in cash the amount of the unconverted principal balance of this Note that would otherwise
 be converted into such fractional Units.

&nbsp;&nbsp;&nbsp;&nbsp;(b) **Effect of Conversion**. If the Maker timely receives notice of the Payee's intention to
 convert this Note at least two business days prior to the closing of a Business Combination,
 this Note shall be deemed to be converted on such closing date. At its expense, the Maker
 will, upon receipt of such conversion notice, as soon as practicable after consummation of
 a Business Combination, issue and deliver to Payee, at Payee's address as requested
 by Payee in its conversion notice, a certificate or certificates for the number of Units
 to which Payee is entitled upon such conversion (bearing such legends as are customary pursuant
 to applicable state and federal securities laws), including a check payable to Payee for
 any cash amounts payable as a result of any fractional Units as described herein.

3. **Interest.** This Note does not carry any interest on the unpaid principal balance of this Note, provided, that,
 any overdue amounts shall accrue default interest at a rate per annum equal to the interest rate which
 is the prevailing short term United States Treasury Bill rate, from the date on which such payment is
 due until the day on which all sums due are received by the Payee.

4. **Application of Payments.** All payments shall be applied first to payment in full of any costs incurred in the
 collection of any sum due under this Note, including but not limited to reasonable attorney's
 and auditor's fees and expenses, then to the payment in full of any late charges, and finally
 to the reduction of the unpaid principal balance of this Note.

5. **Events of Default.** The following shall constitute an event of default (each, an "**Event of Default** "):

&nbsp;&nbsp;&nbsp;&nbsp;(a) **Failure to Make Required Payments.** Failure by the Maker to pay the principal amount due pursuant
 to this Note more than 5 business days of the Maturity Date.

 by it to the appointment of or taking possession by a receiver, liquidator, assignee, trustee,
 custodian, sequestrator (or other similar official) of the Maker or for any substantial part
 of its property, or the making by it of any assignment for the benefit of creditors, or the
 failure of the Maker generally to pay its debts as such debts become due, or the taking of
 corporate action by the Maker in furtherance of any of the foregoing.

&nbsp;&nbsp;&nbsp;&nbsp;(c) **Involuntary Bankruptcy, etc.** The entry of a decree or order for relief by a court having jurisdiction
 in the premises in respect of the Maker in an involuntary case under any applicable bankruptcy,
 insolvency or other similar law, or appointing a receiver, liquidator, assignee, custodian,

 property, or ordering the winding-up or liquidation of its affairs, and the continuance of
 any such decree or order unstayed and in effect for a period of 60 consecutive days.

&nbsp;&nbsp;&nbsp;&nbsp;(d) **Breach of Other Obligations.** The Maker fails to perform or comply with any one or more of its
 obligations under this Note.

&nbsp;&nbsp;&nbsp;&nbsp;(e) **Cross Default.** Any present or future indebtedness of the Maker in respect of moneys borrowed
 or raised becomes (or becomes capable of being declared) due and payable prior to its stated
 maturity by reason of any event of default, or any such indebtedness is not paid when due
 or, as the case may be, within any applicable grace period.
