Phillips 66: 10-K Risk Factor Changes

In connection with our separation from ConocoPhillips in 2012, we entered into an Indemnification and Release Agreement and certain other agreements pursuant to which ConocoPhillips agreed to indemnify us for certain liabilities, and we agreed to indemnify ConocoPhillips for certain liabilities. Indemnities that we may be required to provide are not subject to any cap and may be significant. Third parties could also seek to hold us responsible for any of the liabilities that ConocoPhillips has agreed to retain. Further, the indemnity from ConocoPhillips may not be sufficient to protect us against the full amount of such liabilities, and ConocoPhillips may not be able to fully satisfy its indemnification obligations. Each of these risks could negatively affect our business, results of operations and financial condition. 35 35 35 35 35 35 Table of ContentsIndex to Financial Statements Table of Contents Index to Financial Statements Table of Contents Index to Financial Statements

We conduct some of our operations, including parts of our Midstream, Refining and Marketing and Specialties (M&S) segments, and our entire Chemicals segment, through joint ventures in which we share control with our joint venture partners. Our joint venture partners may have economic, business or legal interests or goals that are inconsistent with ours or those of the joint venture, or our joint venture participants may be unable to meet their economic or other obligations, and we may be required to fulfill those obligations alone. Failure by us, or an entity in which we have a joint venture interest, to adequately manage the risks associated with any acquisitions or joint ventures could have a material adverse effect on the financial condition or results of operations of our joint ventures and, in turn, our business and operations.

Certain of our plans are based upon the assumption that societal sentiment will continue to enable, and existing regulations will remain in place to allow for, the future development, transportation and use of petroleum-based fuels. A portion of our growth strategy is dependent on our and our joint ventures’ ability to capture growth opportunities in the Midstream and Chemicals segments. Regulatory policy decisions relating to the production, refining, transportation, marketing and use of petroleum-based fuels are subject to political pressures and the influence and protests of environmental and other special interest groups. For example, the construction or expansion of pipelines can involve numerous regulatory, permitting, environmental, political, and legal uncertainties, many of which are beyond our control. We may not be able to identify or execute growth projects, and those that are identified may not be completed on schedule or at the budgeted cost, if at all. In addition, our revenues may not increase immediately upon the expenditure of funds on a particular project. Delays or cost increases related to capital spending programs or the inability to complete growth projects could negatively impact our reputation, results of operations, cash flows and our return on capital employed. Our Energy Research & Innovation organization works to develop new technologies and solutions focused on advancing our business units, including renewable and sustainable fuels research. Our efforts to research and develop new technologies is subject to a multitude of factors and conditions, many of which are out of our control. Examples of such factors include evolving government regulation, the pace of changes in technology, the successful development and deployment of existing or new technologies and business solutions on a commercial scale, competition from third parties in developing new technologies and the availability, timing and cost of equipment. The occurrence of these factors may delay or increase the cost of our efforts, which could negatively impact our reputation, results of operations, cash flows and our return on capital employed.

We maintain insurance coverage in amounts we believe to be prudent, including against many, but not all, potential liabilities arising from operating hazards. We rely on existing liquidity, financial resources and borrowing capacity to meet short-term obligations that would result from uninsured or underinsured liabilities arising from operating hazards, including but not limited to, explosions, fires, refinery or pipeline releases or other incidents involving our assets or operations, including weather events, which could reduce the funds available to us for capital and investment spending and could have a material adverse effect on our business, financial condition, results of operations and cash flows.

The operation of refineries, power plants, fractionators, pipelines, terminals, gas processing facilities and vessels is inherently subject to the risks of spills, discharges or other inadvertent releases of petroleum or hazardous substances. If any of these events had previously occurred or occurs in the future in connection with any of our refineries, pipelines or refined petroleum products terminals, or in connection with any facilities that receive our wastes or byproducts for treatment or disposal, other than events for which we are indemnified, we could be liable for all costs and penalties associated with their remediation under federal, state, local and international environmental laws or at common law, and could be liable for property damage to third parties caused by contamination from releases and spills. 27 27 27 27 27 27 Table of ContentsIndex to Financial Statements Table of Contents Index to Financial Statements Table of Contents Index to Financial Statements

Developments aimed at reducing GHG emissions may decrease the demand or increase the cost for our transportation fuels. Societal attitudes toward these products and their relationship to the environment may significantly affect our effectiveness in marketing our products. Government efforts to steer the public toward non-petroleum-based fuel dependent modes of transportation may foster a negative perception toward transportation fuels or increase costs of our products, thus affecting the public’s attitude toward our major products. Advanced technology and increased use of vehicles that do not use petroleum-based transportation fuels or that are powered by hybrid engines would reduce demand for the motor fuel we produce. We may also incur increased production costs, which we may not be able to pass along to our customers. Additionally, renewable fuels, alternative energy mandates and energy conservation efforts could reduce demand for refined petroleum products. Tax incentives and other subsidies can make renewable fuels and alternative energy more competitive with refined petroleum products than they otherwise might be, which may reduce refined petroleum product margins and hinder the ability of refined petroleum products to compete with renewable fuels. The competition for renewable fuels feedstocks may also increase, negatively impacting the availability of such feedstocks or increasing their cost. These developments could potentially have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our basis for approving large-scale capital-intensive projects, such as the conversion of our San Francisco refinery into a renewable fuels facility, is the expectation that it will deliver an acceptable rate of return on the capital invested. We base these forecasted project economics on our best estimate of future market conditions including the regulatory and operating environment. Most large-scale projects take several years to complete. During this multiyear period, the political and regulatory environments or other market conditions can change from those we anticipate, and these changes could be significant. Supply chain disruptions may also delay projects or increase costs. Accordingly, we may not be able to realize our expected returns from a large investment in a capital project, and this could negatively impact our results of operations, cash flows and our return on capital employed.

Similar to other companies in the industry in which we operate, our financial results are largely affected by the relationship, or margin, between the prices at which we sell refined petroleum, petrochemical and plastics products and the prices for crude oil and other feedstocks used in manufacturing these products. Historically, margins have been volatile, and we expect they will continue to be volatile in the future. The cost of feedstocks and the prices at which we can ultimately sell our products depend on numerous factors beyond our control, including regional and global supply and demand, which are subject to, among other things, production levels, levels of refined petroleum product inventories, productivity and growth of economies, geopolitical risks, such as turmoil in the Middle East, Eastern Europe, and other producing regions, technology advancements and the pace of the energy transition, weather-related damage and disruptions due to other natural or human causes, consumer preferences and the use and availability of substitute products, and governmental regulation. We do not produce crude oil and other feedstocks and must purchase all of the feedstocks we process. The prices for crude oil and refined petroleum products can fluctuate based on global, regional and local market conditions, as well as by type and class of products, which can reduce margins and have a significant impact on our refining, wholesale marketing and retail operations, revenues, operating income and cash flows. The ability of the members of the Organization of Petroleum Exporting Countries (OPEC) to agree on and to maintain crude oil price and production controls and changes in trade flows from events such as the Russia-Ukraine war have also had, and are likely to continue to have, a significant impact on the market prices of crude oil and certain of our products. Also, crude oil supply contracts generally have market-based pricing provisions. We normally purchase our refinery feedstocks weeks before manufacturing and selling the refined petroleum products. We also purchase refined petroleum products produced by others for sale to our customers. Changes in prices that occur between the time we purchase feedstocks or products and when we sell the refined petroleum products could have a significant effect on our financial results. The price of natural gas and crude oil also influences prices for the petrochemical and plastics products we produce and the feedstocks used to manufacture those products. Our Chemicals segment uses feedstocks that are derivatively produced in the processing of natural gas and refining of crude oil, and those feedstock prices can fluctuate widely for a variety of reasons, including changes in worldwide energy prices and the supply and availability of the feedstocks. Due to the highly competitive nature of most of the products sold by our Chemicals segment, market position cannot necessarily be protected by product differentiation or by passing on cost increases to customers. As a result, price increases in raw materials may not correlate with changes in the prices at which petrochemical and plastics products are sold, thereby negatively affecting margins and the results of operations of our Chemicals segment. Sustained or prolonged declines in commodity prices and margins for our products may adversely affect our results of operations, liquidity, access to the capital markets, and our ability to fund our capital priorities, including share repurchases and dividends. 21 21 21 21 21 21 Table of ContentsIndex to Financial Statements Table of Contents Index to Financial Statements Table of Contents Index to Financial Statements

Increasing attention to global climate change has resulted in increased investor attention and an increased risk of public and private litigation, which could increase our costs or otherwise adversely affect our business. Additionally, cities, counties, and other governmental entities in several states in the U.S. began filing lawsuits against energy companies in 2017, including Phillips 66, seeking damages allegedly associated with climate change, and the plaintiffs are seeking unspecified damages and abatement under various tort theories. Similar lawsuits may be filed in other jurisdictions. While we believe these lawsuits are an inappropriate vehicle to address the challenges associated with climate change and will vigorously defend against them, the ultimate outcome and impact to us of any such litigation cannot be predicted with certainty, and we could incur substantial legal costs associated with defending these and similar lawsuits in the future. Additionally, governments and private parties are also increasingly filing lawsuits or initiating regulatory action based on allegations that certain public statements regarding climate change and other ESG-related matters and practices by companies are false or misleading “greenwashing” that violate deceptive trade practices and consumer protection statutes. Such claims are included in lawsuits filed against energy companies, including Phillips 66. Such lawsuits present a high degree of uncertainty regarding the extent to which energy companies face an increased risk of liability stemming from climate change or ESG disclosures and practices. Efforts have also been made by governments and private parties to shut down energy assets by challenging operating permits, the validity of easements or the compliance with easement conditions. Lawsuits and/or regulatory proceedings or actions of this nature could result in interruptions to construction or operations of current or future projects, delays in completing those projects and/or increased project costs, all of which may have a material, adverse effect on our business, financial condition, results of operation and cash flows. These risks may result in unexpected costs, negative sentiments about our company, disruptions in our operations, increases to our operating expenses and reduced demand for our products, which in turn could have an adverse effect on our business, financial condition and results of operations. 30 30 30 30 30 30 Table of ContentsIndex to Financial Statements Table of Contents Index to Financial Statements Table of Contents Index to Financial Statements

Increasing attention to global climate change has resulted in increased investor attention and an increased risk of public and private litigation, which could increase our costs or otherwise adversely affect our business. For example, shareholder activism has recently been increasing in our industry, and shareholders may attempt to effect changes to our business or governance, whether by shareholder proposals, public campaigns, proxy solicitations or otherwise. Additionally, cities, counties, and other governmental entities in several states in the U.S. began filing lawsuits against energy companies in 2017, including Phillips 66. The lawsuits seek damages allegedly associated with climate change, and the plaintiffs are seeking unspecified damages and abatement under various tort theories. Similar lawsuits may be filed in other jurisdictions. While we believe these lawsuits are an inappropriate vehicle to address the challenges associated with climate change and will vigorously defend against them for lacking factual and legal merit, the ultimate outcome and impact to us of any such litigation cannot be predicted with certainty, and we could incur substantial legal costs associated with defending these and similar lawsuits in the future. Additionally, governments and private parties are also increasingly filing lawsuits or initiating regulatory action based on allegations that certain public statements regarding climate change and other Environmental, Social and Corporate Governance (ESG) related matters and practices by companies are false and misleading “greenwashing” that violate deceptive trade practices and consumer protection statutes. While we are currently not a party to any of these lawsuits, they present a high degree of uncertainty regarding the extent to which energy companies face an increased risk of liability stemming from climate change or ESG disclosures and practices. Any of these risks could result in unexpected costs, negative sentiments about our company, disruptions in our operations, increases to our operating expenses and reduced demand for our products, which in turn could have an adverse effect on our business, financial condition and results of operations.

Our information technology and infrastructure, or information technology and infrastructure of our third-party service providers (e.g., cloud-based service providers), may be vulnerable to attacks by malicious actors or breached due to human error, malfeasance or other disruptions, including ransomware and other malware, phishing and social engineering schemes, malicious software, data privacy breaches by employees, insiders or others with authorized access, attempts to gain unauthorized access to our data and systems; and other cybersecurity incidents. Any such incidents could compromise our networks and the information stored there could be accessed, publicly disclosed, lost or stolen. Any such unauthorized access, disclosure or other loss of information could result in one or more of the following outcomes: (i) unauthorized access to or a loss or misuse of intellectual property, proprietary information, or employee, customer or vendor data; (ii) public disclosure of sensitive information; (iii) increased costs to prevent, respond to, or mitigate cybersecurity events, such as deploying additional personnel and protection technologies, training employees, and engaging third-party experts and consultants; (iv) systems interruption; (v) disruption of our business operations; (vi) remediation costs for repairs of system damage, or regulatory fines or penalties; (vii) reputational damage that adversely affects customer or investor confidence; (viii) exposure to legal liability; and (ix) damage to our competitiveness, stock price, and long-term stockholder value. Any of the foregoing can be exacerbated by a delay or failure to detect a cybersecurity incident or the full extent of such incident. Further, we have exposure to cybersecurity incidents and the negative impacts of such incidents related to our critical data and proprietary information housed on third-party IT systems, including cloud-based systems. Additionally, authorized third-party IT systems or software can be compromised and used to gain access or introduce malware to our IT systems that can materially impact our business. Although we devote significant resources to prevent cybersecurity incidents and protect our system and data, we have experienced actual and attempted cybersecurity incidents, and while we do not believe that any of these incidents has had a material effect on our business, operations or financial condition, it is possible that a future incident may have such an effect. A cybersecurity incident may also result in legal claims or proceedings against us by our shareholders, employees, customers, vendors, and governmental authorities (U.S. and non-U.S.). Our infrastructure protection technologies and disaster recovery plans may not be able to prevent a technology systems breach or systems failure, which could have a material adverse effect on our financial position or results of operations. Furthermore, the continuing and evolving threat of cyberattacks has resulted in increased regulatory focus on prevention. To the extent we face increased regulatory requirements, we may be required to expend significant additional resources to meet such requirements. 31 31 31 31 31 31 Table of ContentsIndex to Financial Statements Table of Contents Index to Financial Statements Table of Contents Index to Financial Statements

There have been efforts in recent years aimed at the investment community, including investment advisors, sovereign wealth funds, public pension funds, universities, and other groups, to promote the divestment of fossil fuel companies, as well as to pressure lenders, insurers, and other financial services companies to limit or curtail activities with fossil fuel companies. If these or similar efforts are continued, our stock price, our ability to access capital markets or insure our operations, and our cost of capital may be negatively impacted. Members of the investment community are also increasing their focus on environmental and social (E&S) matters, including practices related to GHG emissions, climate change, business resilience, diversity and inclusion, environmental justice and other E&S matters. As a result, we may face increasing pressure regarding our E&S disclosures and practices. Additionally, members of the investment community may screen companies such as ours for E&S performance before investing in our stock or participating in our financing activities. If we are unable to meet the E&S standards set by these investors, we may lose investors, our stock price may be negatively impacted, our access to capital markets and lenders may be curtailed, and our reputation may be negatively affected. Our efforts to accurately report on E&S-related issues expose us to operational, reputational, financial, legal, and other risks. Standards for tracking and reporting on E&S-related matters, including climate-related matters, have not been harmonized and continue to evolve. Processes and controls for reporting on E&S matters are subject to evolving and disparate standards of identification, measurement, and reporting on such metrics, including any climate change and E&S-related public company disclosure requirements adopted by the SEC, and such standards may change over time, which could result in significant revisions to our current E&S practices and disclosures. 33 33 33 33 33 33 Table of ContentsIndex to Financial Statements Table of Contents Index to Financial Statements Table of Contents Index to Financial Statements

Actions of federal, state, local and international governments through legislation or regulation, executive order, permit or other review of infrastructure or facility development, and commercial restrictions could delay projects, increase costs, limit development, or otherwise reduce our profitability both in the United States and abroad. Any such actions may affect many aspects of our operations, including: •Establishing maximum margins that can be earned on sales of motor fuels or imposing financial penalties on profits earned above established maximum margins. •Limiting or prohibiting our ability to undertake turnaround or other maintenance activities at our refineries. 25 25 25 25 25 25 Table of ContentsIndex to Financial Statements Table of Contents Index to Financial Statements Table of Contents Index to Financial Statements •Requiring permits or other approvals that may impose unforeseen or unduly burdensome conditions or potentially cause delays in our operations. •Further limiting or prohibiting construction or other activities in environmentally sensitive or other areas. •Requiring increased capital costs to construct, maintain or upgrade equipment, facilities or infrastructure. •Restricting the locations where we may construct facilities or requiring the relocation of facilities. For example, in March 2023, the California legislature adopted Senate Bill No. 2 (such statute, together with any regulations contemplated or issued thereunder, SBx 1-2), which, among other things, (i) authorizes the establishment of a maximum gross gasoline refining margin (maximum margin) and the imposition of a financial penalty for profits above the maximum margin, (ii) significantly expands reporting obligations relating to the maintenance and business of our California refineries, which includes reporting requirements to the California Energy Commission (CEC) for all participants in the petroleum industry supply chain in California, (iii) creates the Division of Petroleum Market Oversight within the CEC to analyze the data provided under SBx 1-2, and (iv) authorizes the CEC to regulate the timing and other aspects of refinery turnaround and other maintenance activities in certain instances. The CEC is currently in rulemaking with respect to various aspects of SBx 1-2, and the potential implementation of a financial penalty or any restrictions or delays on our ability to undertake turnaround or other maintenance activities creates uncertainty due to the potential adverse effects on our refining, marketing and midstream operations in California, which may be material to our results of operations, financial condition, profitability and cash flows. We anticipate that other jurisdictions may contemplate similarly focused legislation or actions. The ultimate timing and impacts of SBx 1-2 and any other similarly focused legislation or actions are subject to considerable uncertainty due to a number of factors, including technological and economic feasibility, legal challenges, and potential changes in law, regulation, or policy, and it is not currently possible to predict the ultimate effects of these matters and developments, but they may be significant. For example, adverse effects on the financial performance of our operations in the state of California or the useful lives of the assets related to such operations may result in the recognition of material asset impairment charges and asset retirement obligations. Furthermore, the U.S. government can prevent or restrict us from doing business in foreign countries and from doing business with entities affiliated with foreign governments, which can include state oil companies and U.S. subsidiaries of those companies. The Office of Foreign Assets Control (OFAC) of the U.S. Department of the Treasury administers and enforces economic and trade sanctions based on U.S. foreign policy and national security matters. The effect of any such OFAC sanctions could disrupt transactions with or operations involving entities affiliated with sanctioned countries, and could limit our ability to obtain optimum crude slates and other refinery feedstocks and effectively distribute refined petroleum products. We may face other regulatory changes in the U.S. including, but not limited to, the enactment of tax law changes that adversely affect our industry, new emissions standards, restrictive flaring regulations, and more stringent requirements for environmental impact studies and reviews. Hostilities in the Middle East, Russia or elsewhere or the occurrence or threat of future terrorist attacks could adversely affect the economies of the U.S. and other countries. Other political and economic risks include global health crises; financial market turmoil; economic volatility and global economic slowdown; currency exchange rate fluctuations; short-term and long-term inflationary pressures; rising or prolonged periods of high interest rates; import or export restrictions and changes in trade regulations; supply chain disruptions; civil unrest and other political risks; limitations in the availability of labor to develop, staff and manage operations; and potentially adverse tax developments. If any of these events occur, our businesses and results of operations may be adversely affected. 26 26 26 26 26 26 Table of ContentsIndex to Financial Statements Table of Contents Index to Financial Statements Table of Contents Index to Financial Statements

Other political and economic risks include global pandemics; financial market turmoil; economic volatility and global economic slowdown; currency exchange rate fluctuations; short-term and long-term inflationary pressures; import or export restrictions and changes in trade regulations; supply chain disruptions; acts of terrorism, war, civil unrest and other political risks; limitations in the availability of labor to develop, staff and manage operations; and potentially adverse tax developments. If any of these events occur, our businesses and results of operations may be adversely affected.
