ExxonMobil (XOM): What This Company Actually Does

How ExxonMobil makes money

ExxonMobil pulls crude oil and natural gas out of the ground, converts it at refineries into gasoline, diesel, and plastic feedstock, and sells it to drivers, airlines, and factories worldwide. But the profit isn't evenly spread across that chain: Upstream (drilling) is only 12% of revenue but generated 74% of 2025's profit, while Energy Products (refining and marketing) makes up 76% of revenue but passes most of the crude-oil cost straight through to customers, leaving thin margins.

Where the revenue comes from

Margin = after-tax profit ÷ revenue. Source: 10-K FY2025, p.27-29, 80-81.

Geographically (2025): the U.S. is 42.5% ($137.6B) of revenue, and outside the U.S. is 57.5% ($186.3B). The filing splits geography only into U.S./non-U.S. — no country-level breakdown is disclosed. With more than half of revenue coming from abroad, ExxonMobil is exposed to currency risk and country-specific policy or nationalization risk.

Customers and competitors

Customers are broadly diversified: consumers at gas stations, airlines and shipping companies (jet fuel and marine fuel), chemical and plastics manufacturers (polymer feedstock), and industrial buyers (lubricants). Given the commodity nature of the business, no single customer accounts for 10% or more of revenue — none is disclosed in the filings.

• Chevron (CVX) — the closest direct U.S. competitor, with a heavier weighting toward the Permian Basin and Kazakhstan's Tengiz field, making it relatively more Upstream-dependent than ExxonMobil.
• Shell (SHEL) — a European supermajor with a much larger LNG trading business and a more aggressive push into renewables and low-carbon operations.
• BP (BP) — a smaller supermajor that expanded into renewables in recent years before pivoting back toward a fossil-fuel-centered strategy, shifting direction more frequently than its peers.

The metric that matters most in this sector

Barrel-of-oil-equivalent production shows the true scale of a drilling company, while Return on Average Capital Employed (ROCE) shows how efficiently invested capital converts into profit.

The 2024 Pioneer acquisition pushed Permian production sharply higher, and growth continued into 2025 (the company's highest annual production in 40 years). ROCE, meanwhile, spiked to 24.9% during 2022's high oil prices before easing back to 9.3% as prices normalized.

Leadership and ownership

CEO Darren W. Woods has served as Chairman and CEO since 2017 (elected to the board in 2016) — an internal promotion after joining in 1992 and leading multiple business units over 33 years. There's no founder involvement (the company traces to an 1882 founding, having split off from Standard Oil long ago). The largest shareholders are index-fund managers Vanguard, BlackRock, and State Street — a typical large-cap ownership structure with no controlling founding family.

Capital returns

ExxonMobil has raised its per-share dividend for 43 consecutive years — one of the longest streaks among large-cap stocks. In 2025, it paid 59.7% of net income ($17.2B) as dividends and spent $20.3B on buybacks, returning $37.2B to shareholders in total.

How this company could fail

• Oil and commodity price volatility — with three-quarters of profit coming from a single segment (drilling), a drop in oil prices shakes the entire company. Net income already halved from $55.7B (2022) to $28.8B (2025).
• Energy transition and climate regulation — expanding EV adoption and tightening carbon regulation could structurally reduce long-term oil and gas demand; low-carbon businesses (hydrogen, carbon capture) remain small relative to the company's overall size.
• Geopolitical and political risk — major production facilities sit in politically unstable regions like Guyana and Kazakhstan. In Q2 FY2026, Middle East conflict temporarily halted about 10% of the company's drilling volume.

Five-year financials

ExxonMobil doesn't report a separate "operating income" line, so pretax income (before interest) is used here as the profitability measure. FCF = operating cash flow minus capex. Source: 10-K FY2025, p.71, 73, 74; 10-K FY2023, p.77, 79, 80.

What we still don't know

• When and why the CFO changed from Kathryn Mikells to Neil Hansen isn't determinable from these materials — checking a separate 8-K filing or press release would be needed.
• How much of the 10% production halted by Middle East conflict in Q2 2026 was restored in Q3 requires checking the next quarter's 10-Q.
• What practical effect the July 2026 reincorporation from New Jersey to Texas has on taxes and shareholder rights requires further confirmation.
