Role in the system
What this sector controls
Downstream companies transform raw energy into usable products. Their refinery configurations, feedstock access, logistics, maintenance schedules, and product-market reach connect crude differentials to consumer and industrial demand.
Use this sector to compare downstream companies by refining role, feedstocks, product slate, logistics footprint, marketing channels, and exposure to regional fuel markets.
