Calgary, Alberta--(Newsfile Corp. - August 5, 2026) - Prospera Energy Inc. (TSXV: PEI) (OTC Pink: GXRFF) ("Prospera", "PEI", the "Corporation", or the "Company")

Prospera is pleased to announce the commencement of service rig operations across its core Saskatchewan heavy oil properties. The rig marks the launch of the Company's second half 2026 workover and reactivation campaign, a program designed to convert Prospera's deep inventory of workover and reactivation candidates into near-term, capital-efficient production growth.

Program Overview
The service rig has been mobilized to Luseland and is now executing the first phase of the campaign. This initial program consists of well reactivations with demonstrated historical productivity and significant remaining recoverable reserves, backstopped by success of the 2024/2025 reactivation program as detailed in our Key Wells Report and as seen by the following graph:

This 2024/2025 reactivation program consisted of 17 wells for a total capital expenditure of $1.64MM and which has generated total net operating income of $1.70MM as of June 30, 2026 with several wells continuing to rise in production and cash flows. 5 wells on this program have achieved more than 2X payout demonstrating the robust economics and cash flow generation potential of this prolific asset which is ready to scale.

Capital-Efficient Growth
Reactivations remain the most capital-efficient barrels available to Prospera. The Company's existing wellbores, field infrastructure, and now consolidated 100% working interest position across its Saskatchewan core heavy oil properties allow production to be brought online at a small fraction of the cost of drilling. Prior phases of the reactivation strategy have already proven the model, with wells shut in for more than 20 years successfully returned to production and now contributing meaningfully to corporate volumes.

This campaign builds directly toward the Company's 2026 growth plan and positions Prospera to exit the year at a materially higher production rate. Incremental barrels benefit from a low variable operating cost structure, supportive heavy oil pricing environment and the Company's WCS differential hedge all flowing through to funds from operations and reinforcing Prospera's ongoing balance sheet strengthening initiatives.

Board Update
Further to the news release issued August 3^rd, 2026, Prospera Energy Inc. clarifies that Mr. Christopher Moore's resignation from the Board of Directors, effective July 8^th, 2026, was complete and final due to medical and personal reasons. Mr. Moore does not hold an advisory role, nor does he participate in corporate decision-making or operations for the Company.
