Saudi Aramco is the world's largest hydrocarbon producer by volume and, by a wide margin, the most profitable energy company on earth. It is not primarily a commercial oil company; it is the operating arm of the Saudi state's hydrocarbon endowment, holding an exclusive 40-year Concession (extendable to 60 and potentially 100 years) over essentially all Kingdom hydrocarbons, and carrying a statutory obligation to satisfy domestic demand. That structure produces an unmatched cost position — $3.51 per barrel of oil equivalent lifting cost in 2025 — and reserves of 247.2 billion boe under the Concession term, versus 342.0 billion boe on the Kingdom's own basis. It also produces the company's defining constraint: production levels are a sovereign decision, not a management decision. Aramco is now redeploying that cash engine into three adjacent bets — an ~80% sales-gas capacity expansion to 2030, a global LNG trading portfolio, and large-scale artificial intelligence — while distributing roughly $85 billion a year to shareholders.

### What the Company Does
Aramco is a vertically integrated energy and chemicals group organised into two reporting segments — Upstream and Downstream — supported by six corporate functions (Technical Services, Law, Finance, Technology & Innovation, Strategy & Corporate Development, and Human Resources & Corporate Services).
**Upstream** explores for, develops and produces crude oil, condensate, natural gas and NGL, almost entirely inside Saudi Arabia (plus the Saudi-Kuwaiti Partitioned Zone via Al-Khafji Joint Operations and Aramco Gulf Operations Company). In 2025 the segment produced 12.891 mmboed of hydrocarbons — 10.678 mmbpd of liquids and 11,365 mmscfd of gas — and generated adjusted EBIT of $195.5 billion, which is approximately 98% of group adjusted EBIT before corporate costs and eliminations.
**Downstream** comprises refining, chemicals (principally through the 70%-held SABIC), supply and trading, distribution, retail, base oils, lubricants (Valvoline global products, Luberef) and captive power. Gross refining capacity was 7.8 mmbpd and net refining capacity 4.2 mmbpd at 31 December 2025; net chemicals production capacity was 59.3 mtpa. In 2025 Downstream generated adjusted EBIT of $10.0 billion — a fourfold-plus increase on 2024's $2.4 billion — but reported an IFRS EBIT loss of $2.5 billion after impairments and held-for-sale remeasurement charges concentrated in SABIC.
### The Company's Own Characterisation
Aramco states in the Annual Report 2025 that its vision is "to be the world's preeminent integrated energy and chemicals company, operating in a safe, sustainable, and reliable manner," and that it "strives to deliver value to its shareholders through business cycles by maintaining its preeminence in oil and gas production and its leading position in chemicals, aiming to capture value across the energy value chain, and profitably growing its portfolio." Chairman Al-Rumayyan frames the year around having "delivered multiple crude oil and gas megaprojects that reflect our continued focus on operational resilience and flexibility to support global energy security."
### Independent Characterisation of the Revenue Model
Aramco's revenue model is overwhelmingly **commodity product sales**, not services, subscriptions or licensing. Three structural features distinguish it from Western integrated peers:
**First, the royalty-and-tax structure is the real determinant of earnings, not the oil price alone.** Since 1 January 2020 the Concession Amendment applies a baseline crude royalty of 15% on production valued up to $70/bbl, a marginal 45% between $70 and $100/bbl, and a marginal 80% above $100/bbl. In 2025 Aramco paid SAR 139.6 billion of royalties and SAR 197.3 billion of income tax and zakat — SAR 336.9 billion ($89.8 billion) of statutory payments in a single year. The consequence is that Aramco's earnings are materially *less* geared to high oil prices than a Western major's: above $100/bbl, four-fifths of incremental crude value accrues to the state. The 2026 Strait of Hormuz price spike therefore converts to far less incremental net income than headline realised prices ($108.1/bbl in Q2 2026) would suggest.
**Second, a large slice of "revenue" is not third-party sales at all.** "Other income related to sales" — the price-equalisation compensation the Ministry of Energy pays Aramco for supplying domestic customers at regulated prices — was SAR 111.9 billion in 2025, down from SAR 164.4 billion in 2024. This line is a government transfer, and its decline (higher regulated prices, lower reference equalisation prices) accounted for roughly 40% of the group's 2025 revenue decline.
**Third, downstream exists mainly to place crude, not to earn a standalone return.** In 2025, 53% of Aramco's crude production was absorbed by its own downstream system; 29% went to in-Kingdom wholly-owned and affiliated refineries. Aramco's weighted average ownership in international refineries was 36%, yet it supplied 52% of the crude those refineries ran. Downstream is a demand-security instrument with an option on refining margin, and its FY2025 adjusted EBIT of $10.0 billion — 5% of group adjusted EBIT — should be read in that light.
