Overview of Athabasca Oil Corporation

Athabasca Oil Corporation (“AOC”) is a unique liquids-weighted intermediate energy producer. At AOC, we

proudly and responsibly produce Canadian energy to improve people’s lives. We are passionate, take ownership

of our work, get things done and are great at what we do.

Athabasca currently produces ~40,000 boe/d with a significant growth program underway. Athabasca has

exposure to Canada’s premier resource plays. Thermal Oil boasts >1 billion barrels of top quartile reserves and a

deep inventory of future projects. In addition, Athabasca’s private subsidiary company Duvernay Energy

Corporation is a unique standalone self-funded entity that offers investors pure-play exposure to the Kaybob

Duvernay play and is expected to grow to over 15,000 bbl/d by 2030. Strategically Athabasca has two companies

with independent strategies and capital allocation frameworks.

AOC has positioned itself with strong financial liquidity of ~$445 million (including $316 million in cash), putting it

in an enviable position relative to its peers. The company is resilient to commodity price volatility and is expecting

to generate ~$1.1 Billion of free cash flow over the next five years, while funding its growth initiatives. All free

cash flow is currently returned to shareholders in the form of share buybacks. The combination of production

growth and reduced share count is resulting in cash flow per share growth. The corporate strategy is to continue

to grow our assets, generate significant free cash and provide superior returns to shareholders over the long term.

Sustainability is core to the business with strong governance and a commitment to reducing emissions through its

technology roadmap.
