The only asset-level economics disclosed this quarter, applied to the Upstream vertical alone. Co-venturers have invested more than $55B since 2014 and recovered it about two years ahead of the investment basis, generating more than $13B of incremental revenue and cost savings; the first four FPSOs run roughly 100 kbd above their original basis at about 98% reliability, the fifth sailed in June for 4Q26 startup with 250 kbd of capacity, and the company expects its share of Guyana free cash flow to more than double between 2025 and 2030. What this case does not achieve is the rest of the plan: Chemical and Specialty tonnage, the refining margin and the cost-savings target are all left exactly where the base case puts them, and the ~100 kbd entitlement step still lands in the first projected quarter.

ExxonMobil lifts oil-equivalent barrels and monetises most of them through intersegment transfers to Energy Products, so the reported Upstream line is only the third-party slice. Volume is disclosed every quarter and is the thing management guides to 2030; price is Brent, which nobody guides. The company itself models this segment as volume times unit earnings per oil-equivalent barrel, so a unit driver is the honest shape.

Assumptions & reasoning

  • Revenue per barrel here is $33.13, not the disclosed $97.58 U.S. crude realisation: the segment line is net of intersegment eliminations, so the realisation is a price sensitivity rather than this line's unit price.
  • The first projected quarter carries a 4.43% volume step down: the disclosed ~100 kbd fall in Guyana net entitlement from 3Q26 now that cost recovery is reached, plus the ~100 koebd of Qatar LNG capacity the company says stays offline. The Strait of Hormuz case is conditional and sits in the bear scenario instead.
  • Units are a quarterly barrel count built from the disclosed daily rate across 91 days, so quarters of 90 or 92 days carry about a 1% counting difference the model does not correct.
  • The 2Q26 U.S. natural gas realisation of $0.52/kcf against a $2.90/mbtu Henry Hub is disclosed and unexplained, far outside the $1.75 against $3.55 of 4Q25. It is not extrapolated; the disclosed $90M per $0.10/mbtu annual sensitivity is the gas lever this model relies on.
  • The EBITDA margin is held at 100%, the ceiling the control allows. The brief derives 127% for the basis quarter because transferred barrels sit in the numerator and not the denominator; the $3,664M the cap cannot hold is credited to Energy Products, which buys those barrels, so consolidated EBITDA still reconciles.
