Phillips 66 buys crude oil and other feedstocks rather than producing its own, processes them at refineries in the United States and Europe, and supplies gasoline, diesel and aviation fuel to wholesale marketers, dealers and commercial customers. It also buys other producers’ fuels for resale. Its fuel network uses the Phillips 66, Conoco and 76 brands, and JET in the United Kingdom, alongside unbranded sales. Fuel sales account for most revenue, with marketing handling the largest share of sales to outside customers.
A second business serves oil and gas producers by gathering and processing natural gas and moving and storing oil, fuels and natural gas liquids—the liquids separated from natural gas. Transportation customers pay contractual fees, while parts of its natural gas liquids business also earn from commodity sales. Phillips 66 also co-owns Chevron Phillips Chemical Company (CPChem), which makes petrochemicals and plastics, and receives cash distributions from equity affiliates. Its Rodeo Complex and Humber Refinery turn renewable feedstocks into fuels for sale.
Cash generation depends heavily on fuel selling prices relative to purchased inputs, as well as natural gas liquids prices and chemicals margins. Its pipelines and processing plants need continuing supplies from producers. Renewable-fuel earnings also depend on regulatory-credit values. For U.S. petroleum-based motor fuels, Phillips 66 must meet renewable-fuel requirements by blending renewable fuels or buying compliance credits.
The risk section is the longest, dullest part of the filing. This keeps only what can really hurt you: where it hits, how hard, when it plays out.
Every company claims an edge. Each one is checked against hard numbers like margins and returns: which hold, and which line gives way first.
Marathon Petroleum rivals Phillips 66 in selling refined transportation fuels to retailers and wholesale buyers, with further overlap in natural-gas processing, liquids separated from gas and renewable fuels. Its gasoline and diesel sales offer a comparison for Phillips 66’s fuel business beyond the refinery gate.
Valero competes with Phillips 66 for wholesale transportation-fuel buyers in the United States and United Kingdom, and both sell renewable diesel. Watch Valero’s renewable-diesel business alongside Phillips 66’s sales of fuel made from renewable feedstocks.
HF Sinclair competes with Phillips 66 across U.S. refining, fuel sold through branded outlets, renewable diesel and lubricants. Its branded-fuel sales and lubricants results give separate comparisons for Phillips 66’s marketing and specialties business, rather than refining alone.
PBF Energy competes with Phillips 66 to sell wholesale gasoline, diesel and jet fuel in overlapping U.S. refining regions. Its sales of unbranded fuels to commercial customers and major oil companies are especially relevant to Phillips 66’s largely unbranded Gulf Coast and East Coast sales.
Chevron rivals Phillips 66 in refined fuels and lubricants but also co-owns CPChem, which makes and sells petrochemicals and accounts for Phillips 66’s chemicals business through its 50% stake. CPChem’s polyethylene and other chemical sales therefore matter directly to Phillips 66, not just as a competitor comparison.
Delek US competes with Phillips 66 by refining crude oil and supplying transportation fuels to wholesale buyers in inland U.S. markets. Its fuel sales to inland transportation and industrial customers provide a regional comparison for Phillips 66’s wholesale marketing business.
CVR Energy explicitly names Phillips 66’s Ponca refinery as a rival for Mid-Continent refined-fuel customers. Watch its fuel pricing and supply reliability at Coffeyville and Wynnewood, the concrete grounds on which it competes for those regional buyers.
Par Pacific competes with Phillips 66 in refining and selling fuel in the Northwest and Rocky Mountain regions. Its fuel-outlet business in Washington and Idaho offers a local comparison for Phillips 66’s fuel marketing, rather than a nationwide one.
ExxonMobil competes with Phillips 66 in selling petroleum products, petrochemicals and specialty products, but its oil and gas production makes total earnings a less direct comparison. Its results from selling those manufactured products are more relevant to Phillips 66 than the group total.
Cenovus remains a U.S. refining rival after selling its stakes in Wood River and Borger to Phillips 66 on October 1, 2025. Its remaining Lima, Superior and Toledo operations—not the two former joint-venture refineries—are the relevant comparison for sales of refined fuels such as gasoline and diesel.
BP competes with Phillips 66 by refining oil and selling fuel through branded outlets. Its customers & products results cover that rivalry, though the segment also includes oil trading and other customer-facing businesses, so it is not a pure refining comparison.
Sunoco both buys branded fuel from Phillips 66—one of its largest suppliers by volume—and competes with it to supply dealers and commercial fuel buyers. Its branded-fuel supply agreements, generally starting with three- to five-year terms, are worth watching for Phillips 66’s wholesale sales channel.
SunocoCorp gives investors exposure to Sunoco’s fuel-distribution business, which competes with Phillips 66 to supply dealers and commercial buyers. Sunoco’s fuel-distribution results are the relevant comparison for Phillips 66’s wholesale fuel sales, rather than its refining operations.
Enbridge and Phillips 66 both transport oil and gas and share economic interests in DCP Midstream and Gray Oak Pipeline, tying them to North American production and pipeline volumes. Enbridge’s news on Gray Oak is particularly relevant because it manages the ownership class linked to that pipeline, while Phillips 66 holds an indirect stake.
Calumet competes with Phillips 66 in lubricants sold to consumer-facing and industrial markets, and in renewable diesel and aviation fuel for western North America. Its Montana Renewables fuel sales offer a comparison for Phillips 66’s Rodeo production, which mainly serves California, Oregon and Washington customers.
EIA Crude Oil Stocks Change (Oct/16)
For Phillips 66, weekly crude-oil and gasoline stock counts show whether supply is building or tightening against demand, which can move the crude and fuel prices behind refinery margins and the volumes using its refineries, pipelines and terminals.
Read crude and gasoline stocks together for clues about supply and demand: building stocks may signal weaker demand or more supply, pressuring Phillips 66's refining margins and potentially throughput; falling stocks may signal tighter conditions that support margins and volumes.
Valero Energy Corporation earningsVLO
Valero’s report will show how buyers’ demand and pricing for renewable diesel inform the market for Phillips 66’s renewable-feedstock fuels.
Look at Valero’s renewable-diesel sales and business results. Improving sales and results would indicate stronger demand or pricing in this shared market, a more supportive setting for Phillips 66’s renewable-fuel sales. Weakening sales or results would indicate that buyer demand or prices are not supporting the market, adding pressure to Phillips 66’s renewable-fuel business.
PHILLIPS 66 earningsThis company
Phillips 66’s report will show whether the gap between refined-fuel prices and the crude and other inputs it buys is turning into profit in its own refining business.
Read realized refining margin alongside Refining income before taxes. The margin tracks refinery-product revenue less feedstock costs; segment income also reflects throughput, product yields, turnaround activity and operating costs. A higher margin with a narrower loss or a profit would show better product pricing reaching the refining business. A higher margin without improved segment income would show costs or operating factors absorbing the gain.
Chevron Corporation earningsCVX
Chevron’s report on CPChem will show how chemical customers’ demand and prices affect the business Phillips 66 owns half of.
Look at CPChem’s chemical sales volumes alongside its earnings contribution. Rising sales and higher earnings would show customers buying more, or prices supporting profits, and a stronger contribution to Phillips 66. Falling sales or earnings would point to weaker demand, pricing or margins, and less support from Phillips 66’s chemicals investment.
SUNOCO L.P. earningsSUN
Sunoco’s report will show what its branded-fuel purchases and distribution say about demand through Phillips 66’s wholesale channel.
Read Sunoco’s fuel purchases alongside its distribution results. More purchases and steady distribution would show fuel continuing to move through this major customer to dealers and commercial buyers, supporting Phillips 66’s wholesale channel. Weaker purchases or distribution would point to softer demand through that route, but Sunoco’s results alone cannot establish a change in Phillips 66’s sales.
