ExxonMobil (XOM) — threat to the moat

A lubricant franchise is a claim on the number of internal combustion engines in the world, and on how often they need draining.

A lubricants franchise is a claim on the number of internal combustion engines running in the world, and that is the one variable in this business whose direction is not in doubt, only its speed.

Specialty Products: earnings per tonne$398/t2024$367/t2025$3,052m on 7,666 thousand tonnes, then $2,857m on 7,791. Volume up, realised margin down.
A product that gets better at the rate its market shrinks is running to stand still.

ExxonMobil lists it among the factors affecting demand for its products: technological improvements in energy efficiency, increased competitiveness of or government policy support for alternative energy sources, changes in technology that alter fuel choices, and changes in customer or consumer preferences including consumer demand for alternative-fuelled or electric transportation1. An electric vehicle uses a fraction of the lubricant a petrol car uses, and the fraction it does use is a different product.

The timing question is more forgiving than the headlines suggest. Passenger cars are a minority of lubricant volume by value; the profitable end is marine, aviation, mining, rail, industrial machinery and heavy transport, where electrification is slower, harder and in some cases not in prospect at all. A mining truck and a container ship will burn fuel and need oil for decades.

The more immediate pressure is different and less discussed: longer drain intervals. Every improvement in lubricant technology — including ExxonMobil's own — extends the time between oil changes, which reduces the volume sold per engine. A business whose product gets better at the rate its market shrinks is running to stand still, and Specialty Products volumes did exactly that in 2025, rising from 7,666 to 7,791 thousand metric tons2 while earnings fell from $3,052 million to $2,857 million3.

There is a real offset. ExxonMobil is directing the segment toward products where the end market is growing — performance chemicals, synthetics, elastomers and resins, and the Proxxima resin systems it has now committed a 120 thousand tonne a year Louisiana expansion to4.

Volume is not where the problem would show first. It is earnings per tonne. Specialty Products earned $2,857 million on 7,791 thousand tonnes in 2025 and $3,052 million on 7,666 in 20245 — $367 a tonne against $398. Two more years of that trend would mean the differentiation is eroding rather than the market.

    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.
