PERPETUAL ENERGY INC. REPORTS SECOND QUARTER 2023 FINANCIAL AND OPERATING RESULTS AND CONFIRMS 2023 GUIDANCE

Perpetual Energy Inc. has released its second quarter 2023 financial and operating results, and reconfirmed 2023 guidance. Select financial and operational information is outlined below, and should be read in conjunction with Perpetual's unaudited condensed interim consolidated financial statements and related Management's Discussion and Analysis ("MD&A") for the three and six months ended June 30, 2023, which are available through the Company's website and SEDAR+.

SECOND QUARTER 2023 HIGHLIGHTS

• Second quarter production averaged 6,532 boe/d with production increases from two (1.0 net) wells drilled in East Edson, offset by approximately 574 boe/d of curtailed production related to the Alberta forest fires. The Company remains on track to achieve previous 2023 production guidance of 6,400 to 6,600 boe/d as a result of strong well performance from the new East Edson drills.
• Adjusted funds flow(1) was $3.7 million ($0.05/share) in the second quarter of 2023. On a unit-of-production basis, adjusted funds flow was $6.20/boe. Net cash flows from operating activities were $8.3 million.
• Perpetual invested $1.8 million to finish the completion, equip and tie-in of the two (1.0 net) wells drilled during the first quarter at East Edson targeting the Wilrich formation. In addition, $0.3 million was spent on asset retirement obligations ("ARO") during the second quarter to abandon wells that had reached their end of life and execute surface lease reclamation activities.
• Cash costs(1) were $10.0 million or $16.88/boe in the second quarter of 2023, inline with expectations for annual cash cost guidance of $16 to $18 per boe for 2023.
• Net loss for the second quarter of 2023 was $4.2 million.
• Net debt(1) was $56.7 million at June 30, 2023, an increase of $1.0 million from $55.7 million at December 31, 2022.
• Perpetual had available liquidity(1) at June 30, 2023 of $15.8 million, comprised of the $30.0 million borrowing limit of Perpetual's first lien credit facility, less current borrowings and letters of credit of $12.9 million and $1.3 million, respectively.

2023 OUTLOOK

Perpetual's Board of Directors previously approved annual exploration and development capital spending(1) of $25 - $32 million for 2023. As planned, two (1.0 net) wells were drilled at East Edson in the first quarter. The remainder of the 2023 capital program is expected to be concentrated in the third quarter of 2023 and focused primarily at East Edson. The 2023 capital program is forecast to be fully funded from the Company's credit facility and adjusted funds flow(1).

During the second half of 2023, Perpetual is planning to participate at its 50% working interest in an East Edson drilling program to drill, complete, equip and tie-in an additional four to six (2.0 to 2.8 net) horizontal wells to fill the West Wolf gas plant in order to optimize production and operating costs, meet transportation commitments and maximize natural gas and NGL sales through next winter.

At Mannville in Eastern Alberta, Perpetual continues to monitor performance of the horizontal, multi-lateral wells drilled in 2022 targeting heavy oil in the Sparky formation, and is operationally prepared to drill up to one follow-up multi-lateral well in the second half of 2023. Perpetual will also continue to focus on waterflood optimization and battery consolidation projects as well as abandonment and reclamation activities at the Mannville property.

Exploration and development capital spending for full year 2023 continues to be forecast at $25 to $32 million. The table below summarizes anticipated capital spending and drilling activities for Perpetual for the full year of 2023.

Total Company average production is expected to be stable year over year at 6,400 to 6,600 boe/d (22% oil and NGL) in 2023. Cash costs(1) are expected to be similar to 2022 levels with an average between $16 and $18 per boe for the calendar year.

2023 guidance assumptions, which are unchanged are as follows:

Perpetual will continue addressing end of life ARO, with total abandonment and reclamation expenditures of approximately $1.5 to $2.0 million planned for 2023. This exceeds the Company's annual area-based closure mandatory spending requirement of $1.4 million as calculated by the Alberta Energy Regulator ("AER").
