Feedstock throughput capacity sets physical scale, while utilization and throughput show realized activity and product yield shows output mix. Refining margin per barrel is reduced by operating costs and depreciation and amortization to reach adjusted operating income per barrel, while RVO cost adds a separate compliance-cost benchmark whose treatment in realized margin must be checked.

About this market data
IEX historical data reflects IEX activity only and is presented as a source-scoped reference point, not as consolidated U.S. market history.
Screened reference metrics use K9-qualified IEX reference history and only explicitly registered positive split events. They do not assert complete split history, consolidated U.S. market performance, or canonical adjusted prices.
Data provided for free by IEX. By accessing or using IEX Historical Data, you agree to the IEX Historical Data Terms of Use.
The raw chart can show a discontinuity around a stock split because it is intentionally unadjusted. The screened metrics use only explicitly registered positive split events and do not assert complete split history.
