⚠ High Returns on a Tiny Base Attract Capital That Lowers ThemLow threat

ExxonMobil (XOM) — threat to the moat

Every route to making the best business bigger runs through something that makes it worse.

A business earning 35.4 per cent on $8 billion is a wonderful thing to own and an almost impossible thing to grow. Every route to making it larger runs through something that lowers the return.

Every route to making a 35 per cent business bigger runs through something that makes it worse.

Buying share means cutting price, and price is the whole of the differentiation — a lubricant that competes on cost is a lubricant that has stopped being specified. Buying a competitor means paying a multiple that reflects the returns, which converts a 35 per cent business into a mid-teens one the moment the goodwill lands on the balance sheet. Building capacity means adding capital to a market that is not growing: Specialty Products volumes went from 7,666 to 7,791 thousand metric tons in a year1, and the world does not need much more lubricant than it currently uses.

The evidence that ExxonMobil understands this is the spending. Specialty Products consumed $623 million of cash capital expenditure in 2025, about two per cent of the company's total2, and the segment's capital employed has been essentially flat at around $8 billion3. That is a company harvesting a good business rather than trying to scale it, which is usually the right answer and is also an admission that the best thing it owns cannot be made bigger.

Where growth is being attempted is at the edges, in products whose markets do not exist at scale yet: the 120 thousand tonne a year Proxxima blending expansion in Louisiana, taken to final investment decision in 20264, sits in a resin systems business that is a rounding error today.

There is a further wrinkle. Segment returns are calculated on transfers at estimated market prices5, so the basestock that Energy Products supplies to Specialty Products is charged at a market price. A change in that internal transfer price would move earnings between the two segments and change the 35.4 per cent without anything happening in the world.

The warning sign would be the return itself falling as capital rises. Specialty Products at 35.4 per cent on $8,073 million6 is the base case. A segment at twenty per cent on twenty billion would be worth more in dollars and would mean the differentiation had been diluted to buy the growth.
