⚠ The Hedge Only Works While Both Halves Are Still OwnedModerate threat

ExxonMobil (XOM) — threat to the moat

Every refinery ExxonMobil closes improves the return and narrows the hedge that justified owning refineries at all.

An internal hedge requires owning both sides of it, and ExxonMobil has been selling one side. Worldwide refinery throughput fell from 3,936 thousand barrels a day in the second quarter of 2025 to 3,562 in 2026. Europe went from 969 to 814 and Asia Pacific from 442 to 317 — a quarter of the Asian system in a year1. Over the same period the company exited Thailand operations, sold the Singapore retail fuels business, sold Mobil Argentina and sold Product Solutions affiliates in France2.

Refinery throughput, Q2 2025 against Q2 20261,908United States814Europe317Asia Pacific331CanadaQ2 2026, thousand barrels a day. Europe was 969 and Asia Pacific 442 a year earlier.
A quarter of the Asian refining system went in a year, and every closure narrows the hedge.

Each of those decisions is individually correct. A subscale European refinery competing against Middle Eastern and Indian plants built in the last decade earns nothing over a cycle, and ExxonMobil has been ruthless about divesting assets that no longer meet its strategic objectives3. Energy Products returned 19.7 per cent on capital employed in 2025 against 11.7 per cent in 20244, and part of that improvement is arithmetic from a smaller, better denominator.

The cost is that the hedge shrinks with the asset base. A company with 3.6 million barrels a day of refining capacity against 4.5 million of production is meaningfully hedged; one with two million against five is much less so. Every closure raises the company's net exposure to the crude price, which is the exposure the integration exists to damp.

There is a second-order effect that is easy to miss. The remaining system is concentrated in the United States Gulf Coast, where ExxonMobil has the advantaged position, and management cited strong Gulf Coast utilisation and record diesel production in the second quarter of 20265. Concentration improves the average return and reduces the geographic diversification of the hedge at the same time.

Follow the ratio of refinery throughput to oil-equivalent production. It was 3,979 to 4,736 thousand barrels a day in 2025 — about 0.846. If it keeps falling, ExxonMobil is becoming a producer with a refining business attached rather than an integrated company, and should be valued like one.

    Moat Explorer calculation from ExxonMobil's reported figures. Crude oil and product purchases of $184,248 million against total costs and other deductions of $290,970 million is 63.3% (2024: $199,454m of $300,712m = 66.3%; 2023: $193,029m of $291,799m = 66.2%). Intersegment revenue of $121,005 million against gross segment revenue of $452,209 million is 26.8%. Depreciation and depletion of $25,993 million against sales of $323,905 million is 8.0% (2023: $20,641m of $334,697m = 6.2%). Income tax of $11,504 million on pre-tax income of $41,268 million is 27.9% (2024: $13,810m of $48,873m = 28.3%; 2023: $15,429m of $52,783m = 29.2%). Revenue outside ASC 606 of $96,996 million of $323,905 million is 29.9% (2024: 27.7%; 2023: 23.4%). The three downstream segments sum to $17,493m (2023), $9,662m (2024) and $11,080m (2025), a rise of $1,418m in 2025 against an Upstream fall of $4,036m. Refinery throughput of 3,979 against production of 4,736 thousand barrels a day is 0.84. Specialty Products earned $2,857m on 7,791 thousand tonnes ($367/t) against $3,052m on 7,666 ($398/t). Free cash flow of $51,970m less $28,358m is $23,612m against distributions of $17,231m plus $20,273m = $37,504m. Energy Products averaged $7.9 billion a year across 2023-2025. — FY2023-FY2025 · publ.
