Item 1.01 Entry into a Material Definitive Agreement.

 

As of May 6, 2026, Pono Capital Four, Inc. (the “Company”) issued an unsecured promissory note (the “Note”) in the principal amount of up to $100,000 to Mehana Capital LLC (the “Sponsor”). The Company can draw down on the Note up to $100,000 and the Sponsor will fund each request no later than five business days after receipt thereof. The funds are for costs reasonably related to the Company’s business combination. The Note bears no interest and is payable in full upon the consummation of the Company’s initial business combination (the “Maturity Date”).

PROMISSORY NOTE

 

Principal Amount: Up to $100,000 Dated as of May 6, 2026

 

Pono Capital Four, Inc., a Cayman Islands exempted company (the “Maker”), promises to pay to the order of Mehana Ventures LLC, its registered assigns or successors in interest (the “Payee”), the principal sum of up to One Hundred Thousand Dollars ($100,000) in lawful money of the United States of America, on the terms and conditions described below. All payments on this promissory note (the “Note”) shall be made by check or wire transfer of immediately available funds or as otherwise determined by the Maker to such account as the Payee may from time to time designate by written notice in accordance with the provisions of this Note.

 

1.Principal. Maker and Payee agree that Maker may request up to One Hundred Thousand Dollars ($100,000.00) for costs reasonably related to Maker’s initial business combination. The principal balance of this Note shall be repayable on the date on which Maker consummates an initial business combination (such date, the “Maturity Date”). The principal balance may be prepaid at any time.

 

2.Interest. No interest shall accrue on the unpaid principal balance of this Note.

 

3.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 (without limitation) reasonable attorney’s fees, then to the payment in full of any late charges and finally to the reduction of the unpaid principal balance of this Note.

 

4.Drawdown Requests. The principal of this Note may be drawn down from time to time prior to the Maturity Date upon written request from Maker to Payee (each, a “Drawdown Request”). Each Drawdown Request must state the amount to be drawn down agreed upon by Maker and Payee. Payee shall fund each Drawdown Request no later than five (5) business days after receipt of a Drawdown Request; provided, however, that the maximum amount of drawdowns collectively under this Note is One Hundred Thousand Dollars ($100,000). Once an amount is drawn down under this Note, it shall not be available for future Drawdown Requests even if prepaid. No fees, payments or other amounts shall be due to Payee in connection with, or as a result of, any Drawdown Request by Maker. Notwithstanding the foregoing, 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 (without limitation) reasonable attorneys’ fees, and then to the reduction of the unpaid principal balance of this Note.

 

 

 

5.Events of Default. The following shall constitute an event of default (“Event of Default”):

 

(a)Failure to Make Required Payments. Failure by Maker to pay the principal of this Note within five (5) business days following the date when due.

(c)Involuntary Bankruptcy, Etc. The entry of a decree or order for relief by a court having jurisdiction in the premises in respect of maker in an involuntary case under any applicable bankruptcy, insolvency or similar law, for the appointing of a receiver, liquidator, assignee, custodian, trustee, restructuring officer, sequestrator (or similar official) for Maker or for any substantial part of its property, or ordering the winding-up or liquidation of the affairs of Maker, and the continuance of any such decree or order unstayed and in effect for a period of 60 consecutive days.

(b)Upon the occurrence of an Event of Default specified in Sections 4(b) and 4(c), the unpaid principal balance of this Note, and all other sums payable with regard to this Note, shall automatically and immediately become due and payable, in all cases without any action on the part of Payee.
