Phillips 66

Moat components assessed as of late 2025: Efficient scale (midstream pipelines, fractionation, export terminal): strong in local basins and along PSX’s NGL path, aided by long lead times and permitting constraints; 70/100. Switching costs: moderate where long‑term contracts and destination optionality (fractionation/export) create friction; 60/100. Cost advantages: moderate from integrated crude‑to‑chemicals logistics, WRB consolidation, and refining cost reductions; 55/100. Intangibles/brands (Phillips 66/76): modest; 45/100. Network effects: minimal; 20/100. Weighted by relevance (efficient scale 35 percent, switching costs 25 percent, cost advantage 25 percent, intangibles 10 percent, network 5 percent) yields ~57/100. Durability is improving as PSX leans into midstream and CPChem projects, but refining remains price‑taker and chemicals are commodity‑like.

WRB consolidation and record NGL volumes bolster integration but not a fortress‑level moat.
