Oil Refining Industry

Direct Answer

9 SEC filers are classified under the Standard Industrial Classification code that describes the oil refining industry, and their latest annual reports show $1.01 trillion of combined revenue and a median operating margin of 2.6%. Investors should still evaluate its revenue model, industry-specific KPIs, valuation framework and the risks that can change the group's economics.

Industry Overview

Oil refiners buy crude oil and turn it into gasoline, diesel, jet fuel and other products, earning the difference between product prices and crude cost, called the crack spread. Plant complexity and location decide how much of the spread a refinery keeps. The first numbers to compare across companies here are throughput and utilization, refining margin per barrel and product yield.

Key Industry Metrics

• Throughput and utilization: Barrels of crude processed and the share of capacity used. High utilization spreads fixed costs; outages and turnarounds reduce it and can raise prices for other refiners.
• Refining margin per barrel: Profit per barrel processed, driven by the crack spread and crude differentials. It swings widely with fuel supply and demand, so use averages across the cycle.
• Product yield: Share of each barrel turned into high-value products such as gasoline, diesel and jet fuel. Higher yield from complex plants lifts margin versus those making more low-value output.
• Operating cost per barrel: Energy, labor and maintenance cost per barrel processed. Natural gas prices and plant scale affect it; lower costs preserve margin when spreads narrow.
• Turnaround schedule: Planned shutdowns for major maintenance. They lower throughput and add expense in that period, so plan timing explains part of quarterly variation.

Primary Macro Drivers

• Crack spreads and crude differentials: Margin is product prices less crude cost, so wider spreads and cheaper discounted crude raise refining margin per barrel.
• Fuel demand and inventories: Strong demand and low stocks support product prices, lifting margin and throughput, while high inventories weigh on prices.
• Refinery outages and capacity closures: Fewer operating plants tighten supply and raise spreads for plants still running, though outages at one's own site cut throughput.
• Environmental credit costs: Buying compliance credits adds to operating cost per barrel when a refinery cannot blend enough renewable fuel itself.

Major Risks

• Margin volatility: Spreads can narrow quickly when crude rises faster than product prices, so earnings fluctuate; watch refining margin per barrel and utilization.
• Unplanned outages: Fires or equipment faults stop production while costs continue and may raise product prices for others; watch turnaround schedules and incident reports.
• Credit and compliance costs: Rising prices for renewable credits and emissions rules raise cost per barrel; watch compliance cost disclosures and blending shortfalls.
• Long-term demand decline from electrification: More electric vehicles reduce fuel demand and plant use over time; watch demand forecasts, plant closure announcements and capital allocation.

Industry Characteristics

Oil Refining Filers in the SEC Record

9 companies with annual reports in the dataset are classified by the SEC in the Standard Industrial Classification code 2911. Their latest fiscal years end in 2025, and together they reported $1.01 trillion of revenue. Median revenue growth over the prior year was -5.5%. Median operating margin was 2.6% and median net margin 3.0%. Median total liabilities were 58% of total assets, and 6 of 9 reported a profit in their latest year.

The 8 largest of 9 by revenue. Source: each company's own annual report as filed with the SEC (XBRL data), figures in U.S. dollars. A company's SIC code reflects its main business as the SEC records it, so it can differ from how an index provider or analyst classifies the company, and a diversified group appears under only one code.
