HORIZON PETROLEUM RECEIVES SHAREHOLDER APPROVAL FOR DEBT SETTLEMENT IN SHARES

Further to Horizon Petroleum Ltd.'s press release dated June 16, 2026, the company received shareholder approval at its July 28, 2026, annual general meeting, for its proposal to settle certain outstanding debt to management and fees to directors, and third party invoices for an aggregate amount of $524,000 in exchange for shares of the company at a price of 17.5 cents per common share. The price was the closing price of Horizon's common shares on July 15. The insider debt transaction amounts were a result of deferred salaries of $365,000 since September, 2024, and directors' fees in the amount of $25,000 per each of the four independent directors. The debt settlement in shares is subject to final approval by the TSX Venture Exchange.

Shares for management remuneration owing, directors' fees and third-party invoices

Between September, 2024, and May, 2026, the company accrued management salaries in order to conserve capital while the company advanced the development of its Polish concessions. Management has agreed to settle the outstanding fees and be paid in shares. Furthermore, this aligns management with shareholders and demonstrates their commitment to company and their belief in the long-term value potential of Horizon and the development of the Lachowice gas field in Poland.

The company will settle, subject to final approval by the TSX Venture Exchange, outstanding and accrued management compensation in the amount of $365,000, directors' fees in the amount of $100,000 in aggregate and third party invoices owing in the amount of $59,000 in aggregate, through the issuance of an aggregate of 2,994,286 common shares, at a price of 17.5 cents per common share. The debt settlement was approved by disinterested shareholders at the annual general meeting held on July 28, 2026.

The common shares will be subject to a four-month-and-one-day hold period from the date of issuance in accordance with applicable securities laws.

The participation of directors and officers in the insider debt transaction constitutes related party transactions of the company for purposes of Multilateral Instrument 61-101 -- Protection of Minority Security Holders in Special Transactions. The company is relying on the exemptions from the formal valuation and minority approval requirements found in sections 5.5(a) and 5.7(1)(a) of MI 61-101, as the fair market value of insider debt transaction (as it relates to the insiders' participation) is not more than 25 per cent of the company's market capitalization.
