• Record Free Cash Flow: $115 million of Free Cash Flow supporting return of capital commitments.

Duvernay Energy Quarterly Highlights

• Production: Second quarter production of 3,856 boe/d (80% Liquids), up ~100% from the first quarter and supported by production from new wells. Strong production results with restricted IP90s averaging ~1,000 boe/d (86% Liquids) for each well on the 2-well 100% working interest (“WI”) pad and approximate IP60s averaging ~1,000 boe/d (87% Liquids) for each well on the 3-well 30% WI pad.
• Cash Flow: Adjusted Funds Flow of $16 million with an Operating Netback of $51.46/boe.
• Capital Program: $14 million focused on drilling, completions and readiness for upcoming drilling.

Sanctioning of Leismer Expansion to 40,000 bbl/d

• Progressive Growth: The Company is sanctioning progressive growth to 40,000 bbl/d at Leismer in stages over the next three years. Estimated capital cost is $300 million (~$25,000/bbl/d capital efficiency). The Company expects incremental production in 2026 and 2027, reaching 40,000 bbl/d in 2028. Regulatory approvals are in place.
• Maximize Long-term Free Cash Flow Generation: Expanded scale is expected to drive additional margin growth. The Company can maintain 40,000 bbl/d for approximately fifty years (Proved plus Probable Reserves) at an estimated annual sustaining capital of ~$6/bbl, maximizing long-term Free Cash Flow generation.
• Financial Capacity for Growth and Continued Return of Capital: The Company expects incremental growth capital to be funded well within cash flow while continuing to allocate 100% of Free Cash Flow through its return of capital commitment.

Return of Capital

• 2024 Return of Capital Commitment: Athabasca (Thermal Oil) is allocating 100% of Free Cash Flow (not including Duvernay Energy) to share buybacks in 2024. Year to date the Company has completed $173 million in share buybacks (34.7 million shares at an average price of $4.99/sh) and forecasts 2024 Free Cash Flow of ~$350 million1.
• Focus on Per Share Metrics: A steadfast commitment to return of capital has driven an ~88 million reduction (~14%) in the Company’s fully diluted share count since March 31, 2023.

Corporate Consolidated – Strategic Update

• Value Creation: The Company’s Thermal Oil division provides a differentiated liquids weighted growth platform supported by financial resiliency to execute on return of capital initiatives. Athabasca’s subsidiary company, Duvernay Energy Corporation, is designed to enhance value for Athabasca’s shareholders by providing a clear path for self-funded production and cashflow growth in the Kaybob Duvernay resource play. Athabasca (Thermal Oil) and Duvernay Energy have independent strategies and capital allocation frameworks.
• Consolidated Free Cash Flow Growth: Athabasca’s capital allocation framework is designed to unlock shareholder value by prioritizing multi‐year cash flow per share growth. In 2024, Athabasca forecasts Corporate Consolidated Adjusted Funds Flow of ~$590 million or $1.07/sh, representing ~100% per share growth over 2022 when the Company sanctioned growth to 28,000 bbl/d at Leismer. The Company’s updated outlook targets a 13% net annual production growth (23% per share) and a >20% net Adjusted Funds Flow per share compound annual growth rate during the three-year time to 20272.

Athabasca (Thermal Oil) – Strategic Update

• Large Resource Base: Athabasca’s top-tier assets underpin a strong Free Cash Flow outlook with low sustaining capital requirements. The long life, low decline asset base includes ~1.2 Billion barrels of Proved plus Probable reserves and ~1 Billion barrels of Contingent Resource.
• Strong Financial Position: Prudent long-term balance sheet management is a core tenet of Athabasca’s strategy. The Company has peer leading credit metrics including a Net Cash position of $125 million with Liquidity of $429 million (including $303 million cash). The Company intends to proactively refinance its existing term debt due in late 2026 (US$157 million outstanding) supported by strong business fundamentals and attractive credit markets. Maintaining a similar level of outstanding debt is expected to provide strategic flexibility and business resiliency throughout commodity price cycles.
• Leismer Expansions: Athabasca recently completed an expansion to 28,000 bbl/d at a competitive capital efficiency of $14,000/bbl/d. Following the success of this project and with the constructive commodity price environment, the Company has sanctioned a further expansion to 40,000 bbl/d. This will be completed utilizing a progressive build strategy that adds incremental production in 2026 and 2027 with the full 40,000 bbl/d achieved in 2028. The total capital for this project is estimated at $300 million for a capital efficiency of ~$25,000/bbl/d. The Company can maintain 40,000 bbl/d for approximately fifty years (Proved plus Probable Reserves).
• Hangingstone Activity: The Company recently spud the first of two ~1,400 meter well pairs. Well design with extended reach laterals is expected to drive project capital efficiencies of ~$15,000/bbl/d and will leverage off available infrastructure capacity. These sustaining well pairs will support base production in 2025 and beyond with the objective of ensuring Hangingstone continues to deliver meaningful cash flow contributions to the Company and maintaining competitive netbacks ($51.89/bbl Q2 2024 Operating Netback).
• Corner – Future Growth: The Company’s Corner asset is a large de-risked oil sands asset adjacent to Leismer with 351 million barrels of Proved plus Probable reserves and 520 million barrels Contingent Resource (Best Estimate Unrisked). There are over 300 delineation wells and ~80% seismic coverage, with reservoir qualities similar or better than Leismer. The asset has a 40,000 bbl/d regulatory approval for development with the existing pipeline corridor passing through the Corner lease. The Company has updated its development plans and is finalizing facility cost estimates. Athabasca intends to explore external funding options and does not plan to fund an expansion utilizing existing cash flow or balance sheet resources.
• Significant Multi-Year Free Cash Flow: Inclusive of the progressive growth at Leismer, Athabasca (Thermal Oil) expects to generate $1.4 billion of Free Cash Flow1 during the timeframe of 2024-27. Beyond 2028, the Company can maintain its production base for approximately fifty years (Proved plus Probable Reserves) at an estimated annual sustaining capital of ~$6/bbl, maximizing long-term Free Cash Flow generation. Free Cash Flow will continue to support the Company’s growth and return of capital initiatives.
• Thermal Oil Royalty Advantage: Athabasca has significant unrecovered capital balances on its Thermal Oil Assets that ensure a low Crown royalty framework (~7%1). Leismer is forecasted to remain pre-payout until 20271 and Hangingstone is forecasted to remain pre-payout beyond 20301.
• Exposure to Improving Heavy Oil Pricing: With the start-up of the Trans Mountain pipeline expansion (590,000 bbl/d) in early May, spare pipeline capacity is expected to drive tighter and less volatile WCS heavy differentials. Every $5/bbl WCS change impacts Athabasca (Thermal Oil) Adjusted Funds Flow by ~$85 million annually.
• Tax Free Horizon: Athabasca (Thermal Oil) has $2.5 billion of valuable tax pools and does not forecast paying cash taxes for approximately seven years.

Duvernay Energy – Strategic Update

• Value Creation: Duvernay Energy (“DEC”) is an operated, private subsidiary of Athabasca (owned 70% by Athabasca and 30% by Cenovus Energy). DEC accelerates value realization for Athabasca’s shareholders by providing a clear path for self-funded production and cash flow growth without compromising Athabasca’s capacity to fund its Thermal Oil assets or its return of capital strategy.
• Kaybob Duvernay Assets: Exposure to ~200,000 gross acres in the liquids rich and oil windows with ~500 gross future well locations, including ~46,000 gross acres with 100% working interest.
• Self-Funded Growth: Near-term activity will be funded within Adjusted Funds Flow and initial seed capital. The 2024 program includes drilling and completions of a two-well 100% WI pad and a three-well 30% WI pad along with spudding two additional multi-well pads in the Fall of 2024. The Company has self-funded growth potential to in excess of ~20,000 boe/d (75% Liquids) by the late 2020s1.

Operations Update

Athabasca (Thermal Oil)

Production for the second quarter of 2024 averaged 33,765 bbl/d. The Thermal Oil division generated Operating Income of $162 million (Operating Netbacks - $52.78/bbl at Leismer and $51.89/bbl at Hangingstone) during the period with capital expenditures of $34 million, primarily related to drilling and completions, and progressing the facility expansion at Leismer.

Leismer

Leismer produced a record 26,423 bbl/d during the quarter following the completion of the facility expansion. Current production levels are ~28,000 bbl/d with a steam oil ratio (“SOR”) of ~3x. In Q2 the first set of redrills at Leismer were brought on production. These wells develop bypassed pay utilizing existing facilities, resulting in capital efficiencies <$9,500/bbl/d. The Company plans to drill two additional redrills in Q4 to take advantage of these short-cycle opportunities.

The Company is continuing with progressive growth to increase Leismer production to 40,000 bbl/d (regulatory approved capacity) over the next three years. These capital projects are flexible and highly economic (~$25,000/bbl/d capital efficiency) and will maximize value creation when executed alongside the Company’s return of capital initiatives. Activity over the next three years will include drilling ~20 well pairs (sustaining and growth wells), expanding steam capacity to ~130,000 bbl/d and adding oil processing capacity at the central processing facility. The Company anticipates growth to ~32,000 bbl/d in mid-2026, ~35,000 bbl/d in 2027 and achieving ~40,000 bbl/d capacity in 2028. The project will benefit from installing opportunistically pre-purchased steam generators which reduce the timelines and costs for the project.

Leismer is forecasted to remain pre-payout under the Crown royalty structure until late 20271.

Hangingstone

Production during the quarter averaged 7,342 bbl/d. Non-condensable gas co-injection continues to assist in pressure support, reduced energy usage and an improved SOR averaging ~3.4x year to date. In July, the Company spud two ~1,400 meter well pairs. Well design with extended reach laterals is expected to drive project capital efficiencies of ~$15,000/bbl/d and will leverage off available infrastructure capacity. These sustaining well pairs will support base production in 2025 and beyond with the objective of ensuring Hangingstone continues to deliver meaningful cash flow contributions to the Company and maintaining competitive netbacks. Hangingstone is forecasted to remain pre-payout under the Crown royalty structure beyond 20301.

Alberta Wildfire Update

Athabasca is closely monitoring wildfires in the greater Fort McMurray area.

The safety and well-being of our employees and contractors is our top priority. At this time there has been no impact to operations. Athabasca has a comprehensive emergency response plan in place and is in close communication with relevant government agencies. Proactive measures have been taken over the past weeks, including building fire breaks and clearing trees around project sites.

Athabasca will continue to monitor the situation closely and will provide updates as material new information becomes available.

Duvernay Energy

Production for the second quarter of 2024 averaged 3,856 boe/d (80% Liquids). Duvernay Energy generated Operating Income of $18 million (Operating Netback - $51.46/boe) during the period.

Duvernay Energy brought its two-well 100% working interest pad at 03-18-64-17W5 on production in late April. The pad generated an average restricted 90-day rate of ~1,000 boe/d per well (86% liquids) per well. A three well pad (30% working interest) at 02-03-65-20W5 was brought on production in late May, with an approximate 60-day rate of ~1,000 boe/d (87% liquids) per well. Both pads are performing in-line with management’s expectations and exhibiting strong initial rates with high liquids content. The Company is preparing for the upcoming drilling program that will include spudding a three-well 100% working interest pad in September and a four-well 30% working interest pad in December.

Oil and Gas Information

“BOEs" may be misleading, particularly if used in isolation. A BOE conversion ratio of six thousand cubic feet of natural gas to one barrel of oil equivalent (6 Mcf: 1 bbl) is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. As the value ratio between natural gas and crude oil based on the current prices of natural gas and crude oil is significantly different from the energy equivalency of 6:1, utilizing a conversion on a 6:1 basis may be misleading as an indication of value.

Reserves Information

The McDaniel Report was prepared using the assumptions and methodology guidelines outlined in the COGE Handbook and in accordance with National Instrument 51-101 Standards of Disclosure for Oil and Gas Activities, effective December 31, 2023. There are numerous uncertainties inherent in estimating quantities of bitumen, light crude oil and medium crude oil, tight oil, conventional natural gas, shale gas and natural gas liquids reserves and the future cash flows attributed to such reserves. The reserve and associated cash flow information set forth above are estimates only. In general, estimates of economically recoverable reserves and the future net cash flows therefrom are based upon a number of variable factors and assumptions, such as historical production from the properties, production rates, ultimate reserve recovery, timing and amount of capital expenditures, marketability of oil and natural gas, royalty rates, the assumed effects of regulation by governmental agencies and future operating costs, all of which may vary materially. For those reasons, estimates of the economically recoverable reserves attributable to any particular group of properties, classification of such reserves based on risk of recovery and estimates of future net revenues associated with reserves prepared by different engineers, or by the same engineers at different times, may vary. The Company's actual production, revenues, taxes and development and operating expenditures with respect to its reserves will vary from estimates thereof and such variations could be material. Reserves figures described herein have been rounded to the nearest MMbbl or MMboe. For additional information regarding the consolidated reserves and information concerning the resources of the Company as evaluated by McDaniel in the McDaniel Report, please refer to the Company’s AIF.

Reserve Values (i.e. Net Asset Value) is calculated using the estimated net present value of all future net revenue from our reserves, before income taxes discounted at 10%, as estimated by McDaniel effective December 31, 2023 and based on average pricing of McDaniel, Sproule and GLJ as of January 1, 2024.

The 500 gross Duvernay drilling locations referenced include: 37 proved undeveloped locations and 76 probable undeveloped locations for a total of 113 booked locations with the balance being unbooked locations. Proved undeveloped locations and probable undeveloped locations are booked and derived from the Company's most recent independent reserves evaluation as prepared by McDaniel as of December 31, 2023 and account for drilling locations that have associated proved and/or probable reserves, as applicable. Unbooked locations are internal management estimates. Unbooked locations do not have attributed reserves or resources (including contingent or prospective). Unbooked locations have been identified by management as an estimation of Athabasca’s multi-year drilling activities expected to occur over the next two decades based on evaluation of applicable geologic, seismic, engineering, production and reserves information. There is no certainty that the Company will drill all unbooked drilling locations and if drilled there is no certainty that such locations will result in additional oil and gas reserves, resources or production. The drilling locations on which the Company will actually drill wells, including the number and timing thereof is ultimately dependent upon the availability of funding, commodity prices, provincial fiscal and royalty policies, costs, actual drilling results, additional reservoir information that is obtained and other factors.
