PETROFRONTIER CORP. PROVIDES UPDATE ON THE FILING OF ITS 2024 ANNUAL FINANCIAL STATEMENTS

Further to Petrofrontier Corp.'s news release issued on May 2, 2025, whereby the company announced that the Alberta Securities Commission, as principal regulator of the company, issued a management cease trade order (MCTO) 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, there will be a continued delay in the filing of the annual filings.

Petrofrontier continues to work closely with its auditor MNP LLP and is making every effort to submit the annual filings in a timely fashion. It expects to file no later than May 30, 2025, and confirms that since the corporation's news release dated May 2, 2025, there is no other material information concerning the affairs of the company that has not been generally disclosed.

The MCTO prohibits the CEO and the CFO from trading in securities of Petrofrontier for so long as the annual filings are not filed. The issuance of the MCTO does not affect the ability of persons other than the CEO and the CFO of the company to trade in the company's securities.

Until the annual filings have been filed, the company confirms that it intends to continue to satisfy the provisions of the alternative information guidelines specified in NP 12-203 for so long as it remains in default as a result of the late filing of the annual filings by issuing biweekly default status reports in the form of further news releases.
