IMPERIAL OIL LTD (IMO) stock intrinsic value fair value estimate & owner earnings analysis

Imperial Oil is one of Canada's largest integrated oil companies and is about 69.6% owned by ExxonMobil. It produces bitumen and synthetic crude from the Kearl oil sands mine (70.96% share), the Cold Lake in-situ field and a 25% share of Syncrude, and refines crude at Strathcona (Alberta) and Sarnia and Nanticoke (Ontario), about 434,000 barrels a day of capacity, selling fuels under the Esso and Mobil brands across Canada. Gross production averaged 438,000 oil-equivalent barrels a day in 2025, the highest in over 30 years. Imperial reports in Canadian dollars; per-share values here are converted to US dollars at about US$0.72 per Canadian dollar so they can be compared with the NYSE American quote. How we measure earnings: we start from operating cash flow, remove year-to-year swings in working capital, and subtract all capital spending. Because Imperial's revenue rises and falls with oil prices rather than with new capacity, we treated all capital spending as upkeep; it runs close to the annual depletion charge. Share-based pay is already deducted in reported earnings and is not added back, so no further charge was needed. Depletion and write-downs (including the 2025 impairment of the Calgary campus and the accelerated end of the Norman Wells field) are non-cash and were added back; the using-up of the reserves is instead reflected in how long each case lets cash flow continue. Before interest, the business produced about C$3.2 billion in 2018, C$2.0 billion in 2019, C$0.1 billion in 2020 (the price collapse), C$3.4 billion in 2021, C$7.5 billion in 2022, C$4.9 billion in 2023, C$4.8 billion in 2024 and C$3.7 billion in 2025. We use the middle of 2018-2025, about C$3.58 billion a year (about US$5.31 per share on today's 484.9 million diluted shares), because that window covers a full oil cycle from the 2020 collapse to the 2022 spike. We left out 2016 and 2017, which were hit by the Fort McMurray wildfire and the Syncrude fire. Cash flow fell 22% in 2025, but about C$536 million of pre-tax charges for restructuring and an inventory clean-up were one-time, and first-half 2026 net income of C$3.13 billion was well above the C$2.24 billion of a year earlier, so the base case starts at the cycle level (4% below 2025's actual) rather than extending the decline. The strong 2026 results reflect high oil prices (WTI averaged about US$93 in the second quarter) and are not used to raise the level. Base case (about US$60.69 per share): cash flow holds at C$3.58 billion a year for 15 years, roughly the life of Imperial's 2,036 million barrels of proved reserves at the 2025 production rate, then fades to zero by year 30. The extension beyond proved reserves rests on the record of Cold Lake (producing since 1985, with the Leming redevelopment reaching first oil in November 2025) and Syncrude (since 1978), where routine sustaining spending has kept replacing produced barrels. No production growth, no savings from the 2025 restructuring and no higher oil prices are credited. Bear case (about US$32.65): cash flow of C$2.4 billion a year, slightly below the average of the five weakest years since 2018, when wide Canadian heavy-oil discounts, Alberta production curtailments and the 2020 collapse hit earnings, for 12 years, fading to zero by year 20 with no credit for replacing proved reserves. Rising carbon costs and refining setbacks sit behind this case; Imperial has already cut its 2026 refinery utilization outlook to 85-88% because of unplanned downtime and a rail logistics problem at Strathcona. Bull case (about US$91.09): cash flow of C$4.5 billion a year, in line with 2023-2025 after removing the 2025 one-time charges, supported by record Kearl and Cold Lake volumes and the narrower heavy-oil discount since the Trans Mountain pipeline expansion entered service in May 2024. It holds for 25 years and fades to zero by year 40 on the long-lived oil sands resource. Debt: Imperial owes C$3.45 billion on a variable-rate loan from ExxonMobil (2.7% at year-end 2025; the agreement runs to June 2035 but ExxonMobil can cancel it on 370 days' notice) plus about C$550 million of finance leases, against C$2.84 billion of cash at June 30, 2026, of which we treat about C$2.34 billion as surplus. Net debt is about C$1.66 billion, or US$2.46 per share. The business is worth roughly US$35.11, US$63.15 and US$93.55 per share in the bear, base and bull cases before debt, leaving US$32.65, US$60.69 and US$91.09 for shareholders. Roughly one year of cash flow would repay the loan, so even a cancellation by ExxonMobil would not threaten the company. What changed: our previous estimates were in Canadian dollars and used a higher discount rate with a permanent growth assumption. We now value each case as an explicit story limited by reserve life and show values in US dollars. In Canadian dollars the base case is about C$84 per share, close to the previous C$86, while the bear case is higher (C$45 versus C$32) and the bull case lower (C$127 versus C$153). The margin-of-safety price is about US$37, roughly 39% below the base case, a margin suited to a business whose earnings swing with oil prices, and close to the bear-case value. What would make this wrong: a lasting shift in oil prices or Canadian heavy-oil discounts; reserve additions that run well beyond what we credit (upside); stricter emissions rules or carbon costs that shorten the oil sands' economic life (downside); and ExxonMobil's control over capital allocation and the related-party loan.
