PETROFRONTIER CORP. ANNOUNCES CEASE TRADE ORDER

Further to the news releases issued on April 14, May 2, May 18, May 31 and June 13, 2025, whereby Petrofrontier Corp. announced that the Alberta Securities Commission issued a management cease trade order to Petrofrontier pursuant to its application under National Policy 12-203 (Management Cease Trade Orders) in respect of the default regarding the delay of the filing of its annual financial statements, accompanying management's discussion and analysis, and related chief executive officer and chief financial officer certifications for the financial year ended Dec. 31, 2024, the ASC issued a failure-to-file cease trade order on July 17, 2025. The CTO has resulted in the company's common shares being halted for trading on the TSX Venture Exchange. Petrofrontier is experiencing continued delays with respect to the annual filings related to the receipt of financial and other required information from the general partner of the company's limited partnership investment. The continued delays have impacted on the ability of the company's external auditor to complete the audit.

The company further announces that, because of the delay in filing the annual filings, the company's interim financial statements for the three months ended March 31, 2025, the accompanying management's discussion and analysis, and related chief executive officer and chief financial officer certifications will only be filed following filing of the annual filings.

The company's board of directors and its management are working diligently to meet Petrofrontier's obligations relating to the filing of the annual filings and first quarter filings.
