Here are 1-3 brief analogies to describe Phillips 66 (PSX):

• It's like the vast refining, pipeline, and chemical operations of an ExxonMobil or Shell, but operating as its own company without their oil drilling (upstream) business.
• Think of Phillips 66 as a hybrid of a major independent refiner like Valero Energy and a significant chemical producer akin to a focused division of Dow, all connected by extensive logistics infrastructure.

• Gasoline and Diesel: Fuels refined from crude oil primarily for transportation and power generation.
• Jet Fuel: A specialized kerosene-based fuel used to power turbine engines in aircraft.
• Lubricants: Oils and greases designed to reduce friction and wear in engines, machinery, and industrial applications.
• Natural Gas Liquids (NGLs): Hydrocarbon products like propane, butane, and ethane, which are separated from natural gas and crude oil.
• Petrochemicals: Base chemicals such as ethylene, propylene, and their derivatives, which are fundamental building blocks for plastics and other industrial products.
• Crude Oil and NGL Transportation & Storage: Midstream services involving the movement and holding of crude oil and natural gas liquids through pipelines and terminals.
• Refined Product Marketing: The distribution and sale of refined fuels and other petroleum products to retail stations, commercial customers, and industrial users.

Phillips 66 (NYSE: PSX) primarily operates as a business-to-business (B2B) company, selling its products and services to other companies rather than directly to individual consumers for the majority of its revenue.

Due to the diversified nature of its operations across refining, midstream, chemicals, and marketing, Phillips 66 serves a broad and varied customer base. As is common for large-scale energy and commodity producers, the company does not typically disclose the names of specific major customer companies that represent a significant portion (e.g., 10% or more) of its consolidated revenue in its public filings. Therefore, we cannot list specific customer names with their symbols.

Instead, Phillips 66's major customers generally fall into the following categories of businesses:

• Fuel Marketers and Distributors: These companies purchase gasoline, diesel, jet fuel, and other refined petroleum products in bulk from Phillips 66's refineries. They then distribute these products to a wide array of end-users, including branded and unbranded retail stations, commercial fleets, airlines, and various industrial clients.
• Airlines and Transportation Companies: Direct purchasers of jet fuel for commercial aviation and diesel for trucking, marine, and rail transportation sectors.
• Industrial and Commercial Users: Businesses that utilize petroleum products (such as fuels, lubricants, and asphalt) as essential inputs for their manufacturing processes, operational machinery, construction projects, or agricultural activities.
• Chemical Manufacturers and Processors: Through its 50/50 joint venture, Chevron Phillips Chemical Company LLC, customers include companies that use olefins and polyolefins to produce a vast range of products, such as plastics, synthetic fibers, packaging materials, automotive components, and various other industrial and consumer goods.
• Other Energy Companies: For its midstream operations, Phillips 66 provides services such as gathering, processing, transportation, and storage of crude oil, natural gas, and natural gas liquids (NGLs) to other upstream producers, refiners, and downstream energy companies.

The accelerated global energy transition towards electrification and renewable energy sources poses a clear emerging threat to Phillips 66. This transition is primarily driven by the rapid adoption of electric vehicles (EVs) globally, increasing government mandates and targets for phasing out internal combustion engine (ICE) vehicles, and significant investments by major automakers in EV production. As demand for gasoline, diesel, and jet fuel potentially declines in the long term, Phillips 66's core refining, marketing, and midstream segments, which rely heavily on the processing and distribution of these fossil fuels, face a fundamental challenge to their existing business model and asset utilization.

Phillips 66 (PSX) is expected to drive future revenue growth over the next 2-3 years through strategic initiatives focusing on its Midstream segment, the expansion of its renewable fuels business, and optimized refining operations.

Here are 3-5 expected drivers of future revenue growth:

1. Midstream Segment Expansion and Integration: Phillips 66 is significantly expanding its Midstream operations through strategic acquisitions and organic projects. The company's increased interest in DCP Midstream and the acquisition of Pinnacle Midstream, with an adjacent processing plant commencing operations in mid-2025, are anticipated to grow midstream assets and services. Furthermore, the acquisition of EPIC NGL (completed in January 2025) and expansion projects like the Dos Picos II NGL fractionator (expected online in Q3 2025) are projected to boost Midstream adjusted EBITDA to $4.5 billion by 2027. These expansions and integrations are expected to increase volumes and diversify earnings.
2. Renewable Fuels Production Growth: Phillips 66 is strategically shifting towards renewable fuels, with its Rodeo Renewable Energy Complex being a key growth driver. The execution of projects like "Rodeo Renewed" represents a commitment to new product lines, specifically renewable diesel and other renewable products, which will contribute to the company's top-line revenue as production scales up.
3. Optimized Refining Operations and Higher-Value Product Yields: Phillips 66 is enhancing its refining performance through actions designed to increase reliability, improve market capture, and reduce costs, while also increasing clean product yields. The company has achieved high utilization rates, reaching 99% in its refining segment in Q3 2024, the highest since 2018. Additionally, an improved clean product yield, which stands at 87% year-to-date from 84% three years ago, signifies the production of more valuable products from each barrel of crude processed, thereby increasing revenue. Full ownership of the Wood River and Borger refineries also presents additional high-return organic opportunities.

Share Repurchases

• Phillips 66 suspended its share repurchase program in March 2020 due to the global economic disruption and resumed it in the second quarter of 2022.
• The company had $2.5 billion available under its share repurchase authorization as of April 2022, which has no expiration date.
• Phillips 66 repurchased $1.5 billion in shares in 2022, $4.014 billion in 2023, and $3.451 billion in 2024. In 2023, Phillips 66 repurchased $4 billion in shares.

Outbound Investments

• Phillips 66 agreed to acquire the remaining 50% ownership interest in WRB Refining LP from Cenovus Energy Inc. for $1.4 billion, which was expected to close in the fourth quarter of 2025, giving Phillips 66 full ownership of the Wood River and Borger refineries.
• The company completed the acquisition of EPIC NGL (renamed Coastal Bend) for $2.2 billion, expanding its midstream NGL infrastructure.
• Phillips 66 acquired a Permian G&P asset for almost $600 million. The company also divested its 65% interest in its Germany and Austria retail marketing business for $1.6 billion.
