Permex Petroleum Announces Closing of US$2,000,000 Private Placement of Convertible Debentures

VANCOUVER, BC, July 11, 2025 – Permex Petroleum Corporation (CSE: OIL) (FSE: 75P) (“Permex” or the “Company”) is pleased to announce that, further to its press releases dated July 4, 2025, the Company has closed a private placement (the “Offering”) of convertible debenture units of the Company (the “Units”) for gross proceeds of US$2,000,000.

Pursuant to the Offering, the Company issued 2,000 Units to a single arm’s length subscriber, with each Unit consisting of one convertible debenture (a “Debenture”) in the principal amount of US$1,000 and 393 common share purchase warrants (each, a “Warrant”). Each Warrant is exercisable for a period of five years from the date of issuance for one common share of the Company (a “Share”) at an exercise price of US$2.54.

The Debentures will mature (the “Maturity Date”) one-year from the date of issuance. The Debentures bear simple interest at a rate of 10%, payable on the Maturity Date or the date on which all or any portion of the Debenture is repaid. Interest will be paid in cash or Shares based on a conversion price of US$2.54 (the “Conversion Price”), subject to the approval of the Canadian Securities Exchange (the “Exchange”).

At any time during the term of the Debentures, a holder of Debentures may elect to convert the outstanding principal and any accrued and unpaid interest thereon into Shares at the Conversion Price. The Debentures will automatically convert into Shares, or if elected by the holder, cash, at the Conversion Price in the event the Company completes a financing of Shares for aggregate gross proceeds of at least US$7,500,000. Any conversion of the Debentures which would exceed certain dilution thresholds is subject to the appropriate approvals, including shareholder approval if required by the policies of the CSE.

The proceeds of the Offering are expected to be used for general working capital purposes. No finders’ fees were paid in connection with the Offering.

The Units offered in the Offering have been and will be offered only to persons who either qualify as an “accredited investor” as defined in Rule 501(a) of Regulation D under the United States Securities Act of 1933, as amended (the “U.S. Securities Act”) or who are located outside of the United States and are not a “U.S. person” as defined in Regulation S under the U.S. Securities Act. All securities issued pursuant to the Offering and underlying securities will be subject to a four-month hold period from the date of issuance pursuant to applicable Canadian securities laws, in addition to such other restrictions as may apply under the U.S. Securities Act and other applicable securities laws of jurisdictions outside of Canada.

None of the securities offered in the Offering have been and will not be registered under the U.S. Securities Act or under any U.S. state securities laws and may not be offered or sold in the United States absent registration or any applicable exemption from the registration requirements of the U.S. Securities Act and applicable U.S. state securities laws. This news release shall not constitute an offer to sell or the solicitation of an offer to buy securities in the United States, nor shall there be any sale of these securities in the United States or any jurisdiction in which such offer, solicitation or sale would be unlawful. This news release is being issued pursuant to and in accordance with Rule 135c under the U.S. Securities Act.
