⚠ Three Years of Buybacks Left More Shares OutstandingModerate threat

ExxonMobil (XOM) — threat to the moat

Three years and fifty-eight billion dollars of buybacks left ninety-seven million more shares outstanding than it started with.

ExxonMobil ended 2022 with 4,082 million shares outstanding. Over the next three years it repurchased 165 million, 170 million and 182 million shares — 517 million in total, at a cost of roughly $58 billion1. It ended 2025 with 4,179 million shares outstanding2.

Shares outstanding at year end, in millions4,08220223,97120234,35320244,1792025517 million shares repurchased across the three years, and 545 million issued for Pioneer.
Roughly $58 billion of buybacks, and ninety-seven million more shares outstanding than it started with.

The reconciliation is a single line. In 2024 the company issued 545 million shares for acquisitions3: Pioneer, at a fair value of $63 billion4. Three years at a $20 billion-a-year pace, and the owner of one share at the end of 2022 owns a slightly smaller fraction of the company today.

That is not a scandal and it is not hidden — the share activity table is printed in the 10-K. But it reframes what the buyback is. A repurchase that shrinks the share count returns capital and concentrates ownership. A repurchase that offsets stock issued for an acquisition is a cash payment for an asset, routed through the market, and should be judged on what the asset earns rather than on the buyback yield.

The scale of the commitment makes this more than a historical point. ExxonMobil repurchased $20 billion of stock in 2025 and said in its December 2025 Corporate Plan Update that it expects to continue at a $20 billion pace through 2026, assuming reasonable market conditions5. It bought $10.0 billion in the first half of 20266. At the current price that is roughly three per cent of the company a year, which does shrink the count if no more shares are issued.

The honest counter is that Pioneer's assets will produce for decades and the shares were issued once. Whether that was a good trade is a question about oil prices in the 2030s.

Shares outstanding requires no interpretation at all: 4,082 million at the end of 2022, 3,971 million in 2023, 4,353 million in 2024, 4,179 million in 20257, and roughly 4.11 billion in September 20268. Four consecutive years of a $20 billion buyback should take that number decisively below four billion. If it does not, something else is being funded.
