Phillips 66 turns crude oil into money by processing it at refineries, moving it through pipelines, and selling the finished products at the pump. The company runs five separate businesses: Midstream (pipelines and natural gas processing), Chemicals (a 50% stake in a plastics maker called Chevron Phillips Chemical Company), Refining (10 refineries across the US and Europe), Marketing and Specialties (selling gasoline and lubricants to customers), and Renewable Fuels (making cleaner fuels from plant-based materials at its Rodeo complex in California). Each piece of the business earns money in a different way, but they all connect to the same basic fact: people need fuel, and Phillips 66 sits in the middle of getting it to them. The diagram below traces where the money goes.
Five years of financial data tell a story with a sharp peak and a troubling slide. Revenue jumped from $111.5 billion in 2021 to $170.0 billion in 2022, then fell every single year after that, landing at $132.4 billion in 2025. That peak was not a business breakthrough. It was crude oil prices spiking after Russia invaded Ukraine. When prices normalized, revenue followed them down.
Cash generation tells a similar story, and the direction is harder to ignore. Operating cash flow was $10.8 billion in 2022. By 2024 it had fallen to $4.2 billion. It recovered slightly to $5.0 billion in 2025, but free cash flow after capital spending was just $2.7 billion, compared to $8.9 billion in 2022. At the same time, net debt climbed from $11.1 billion in 2022 to $18.6 billion in 2025. The company is generating less cash while carrying more debt.
The Refining segment, historically the biggest profit engine, lost money in both 2024 and 2025. The West Coast operations were the worst performer, losing $1.248 billion before taxes in 2025 alone. Phillips 66 responded by shutting its Los Angeles Refinery in the fourth quarter of 2025. The Midstream and Marketing and Specialties segments kept the company profitable overall, with Midstream contributing $2.817 billion and Marketing and Specialties contributing $4.500 billion before taxes in 2025. But a large part of that Marketing figure came from one-time asset sales, including a $1.9 billion gain from selling part of its Germany and Austria retail business and a $1.0 billion gain from selling its stake in a Swiss fuel company called Coop.
Refining profitability swings with crack spreads, and those swings are violent. The worldwide realized refining margin was $17.26 per barrel in 2023. It fell to $8.84 per barrel in 2024, then recovered slightly to $10.88 per barrel in 2025. The company cannot choose its margin. It can only try to run its plants efficiently and hope the spread cooperates.
The risks attached to this business are specific and documented. California passed a law called Senate Bill 2 in March 2023 that lets the state set a maximum profit margin on gasoline refining and fine the company if profits exceed that limit. The state can also restrict when Phillips 66 does maintenance at its refineries. California has separately banned new gas-powered cars starting in 2035 and requires carbon neutrality by 2045. These rules could shrink the market that California refineries serve, and the company may not be able to pass all the costs to customers.
The company also faces a mandatory renewable fuel blending requirement from the EPA. If it cannot blend enough renewable fuel itself, it must buy RINs on the open market. When RIN prices rise, that cost comes straight out of refining margins. The Renewable Fuels segment, built partly to address this problem through the Rodeo complex in California, has lost money in both 2024 and 2025. A court also ordered Phillips 66 to pay over $600 million related to a lawsuit with Propel Fuels over trade secrets, and the company recorded $605 million in litigation charges related to that case in 2024 and $262 million more in 2025. The federal government charged Phillips 66 in November 2024 with violating the Clean Water Act by polluting sewers with refinery wastewater.
The company's stated plan is to shrink its refining exposure and grow the Midstream and Chemicals businesses, which carry more predictable, fee-based income. Management has targeted reducing total debt to $17 billion by the end of 2027 and aims to return more than 50% of operating cash flow to shareholders through dividends and share repurchases. The board raised the quarterly dividend to $1.27 per share in February 2026. Those are the goals. Whether the cash engine is strong enough to fund them simultaneously is the unresolved question sitting at the center of the investment case.
