⚠ The Price Is Set Somewhere ElseHigh threat

ExxonMobil (XOM) — threat to the moat

Seven hundred million dollars of earnings per dollar of Brent, decided by people who do not work for ExxonMobil.

Everything in this company is downstream of one sentence in its own risk factors: the oil, gas and petrochemical businesses are fundamentally commodity businesses, which means ExxonMobil's operations and earnings may be significantly affected by changes in oil, gas and petrochemical prices and by changes in margins on refined products1.

Net income, with the same assets, in $m20,8402018-22,440202055,740202228,8442025Bars show magnitude; the 2020 label carries the sign. A $78bn swing in two years.
Seven hundred million dollars of earnings per dollar of Brent, decided by people who do not work here.

The magnitude is disclosed. For 2026, a one dollar per barrel change in the Brent price would have an approximately $700 million annual after-tax effect on Upstream consolidated and equity company earnings, excluding derivatives2. A ten cent change in Henry Hub is worth about $90 million and a ten cent change in TTF about $20 million3.

Apply that to what actually happened. Realised Brent was $82.62 in 2023, $80.76 in 2024 and $69.06 in 20254. The $13.56 fall from 2023 to 2025 is worth roughly $9.5 billion of after-tax Upstream earnings. Net income over the same period went from $36,010 million to $28,844 million5 — a fall of $7,166 million. Everything ExxonMobil did over two years, across four segments, a record production year and $6.0 billion of structural cost savings, was a partial offset to a price move it had no part in.

The extreme version is 2020, when the company lost $22,440 million in a single year6 with essentially the same assets, the same people and the same technology it had used to earn $20,840 million in 20187. The swing from the 2020 loss to the 2022 peak of $55,740 million8 is $78 billion, and almost none of it was caused by anything inside the company.

Who sets the price is not a mystery. Saudi Arabia alone carries roughly three million barrels a day of spare capacity — more than half of ExxonMobil's entire production — and total OPEC+ spare capacity exceeds five million barrels a day, the highest since 20099. That capacity is withheld or released by governments, and ExxonMobil's earnings move by $700 million for every dollar the decision is worth.

The damage is limited by the cost position and the integration: low-cost barrels survive a low price, and three of the four segments benefit when crude falls10. Neither is a substitute for control.

The number to watch is realised Brent, which the company publishes every year. Below roughly $60 sustained, the $20 billion buyback stops before the dividend does; below $45 sustained, the 2020 arithmetic returns.

The number that tests this threat
Reported
After-tax earnings per dollar of Brent
approximately $700 million a year

ExxonMobil’s own disclosed 2026 sensitivity, excluding derivatives; a ten cent move in Henry Hub is worth about $90 million and in TTF about $20 million. Realised Brent went $82.62, $80.76, $69.06 across three years — a $13.56 fall worth roughly $9.5 billion, against a $7,166 million decline in net income. Watch realised Brent; below $60 sustained the buyback stops before the dividend does.
