About Phillips 66

CAUTIONARY STATEMENT FOR THE PURPOSES OF THE “SAFE HARBOR” PROVISIONS

OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

This news release contains forward-looking statements within the meaning of the federal securities laws. Words such as “adjusted EBITDA,” “anticipated,” “estimated,” “expected,” “planned,” “scheduled,” “targeted,” “believe,” “continue,” “intend,” “will,” “would,” “objective,” “goal,” “project,” “efforts,” “strategies” and similar expressions that convey the prospective nature of events or outcomes generally indicate forward-looking statements. However, the absence of these words does not mean that a statement is not forward-looking. Forward-looking statements included in this news release are based on management’s expectations, estimates and projections as of the date they are made. These statements are not guarantees of future performance and you should not unduly rely on them as they involve certain risks, uncertainties and assumptions that are difficult to predict. Therefore, actual outcomes and results may differ materially from what is expressed or forecast in such forward-looking statements. Factors that could cause actual results or events to differ materially from those described in the forward-looking statements include: fluctuations in NGL, crude oil, refined petroleum product and natural gas prices, and refining, marketing and petrochemical margins; changes in governmental policies or laws that relate to NGL, crude oil, natural gas, refined petroleum products, or renewable fuels that regulate profits, pricing, or taxation, or other regulations that limit or restrict refining, marketing and midstream operations or restrict exports; the effects of any widespread public health crisis and its negative impact on commercial activity and demand for refined petroleum products; our ability to timely obtain or maintain permits necessary for capital projects; changes to worldwide government policies relating to renewable fuels and greenhouse gas emissions that adversely affect programs including the renewable fuel standards program, low carbon fuel standards and tax credits for biofuels; our ability to achieve the expected benefits of the integration of DCP Midstream, LP, including the realization of synergies; the success of the company’s business transformation initiatives and the realization of savings and cost reductions from actions taken in connection therewith; unexpected changes in costs for constructing, modifying or operating our facilities; our ability to successfully complete, or any material delay in the completion of, asset dispositions or acquisitions that we may pursue; unexpected difficulties in manufacturing, refining or transporting our products; the level and success of drilling and production volumes around our midstream assets; risks and uncertainties with respect to the actions of actual or potential competitive suppliers and transporters of refined petroleum products, renewable fuels or specialty products; lack of, or disruptions in, adequate and reliable transportation for our NGL, crude oil, natural gas, and refined products; potential liability from litigation or for remedial actions, including removal and reclamation obligations under environmental regulations; failure to complete construction of capital projects on time and within budget; our ability to comply with governmental regulations or make capital expenditures to maintain compliance with laws; limited access to capital or significantly higher cost of capital related to illiquidity or uncertainty in the domestic or international financial markets, which may also impact our ability to repurchase shares and declare and pay dividends; potential disruption of our operations due to accidents, weather events, including as a result of climate change, acts of terrorism or cyberattacks; general domestic and international economic and political developments, including armed hostilities (such as the Russia-Ukraine war), expropriation of assets, and other political, economic or diplomatic developments; international monetary conditions and exchange controls; changes in estimates or projections used to assess fair value of intangible assets, goodwill and property and equipment and/or strategic decisions with respect to our asset portfolio that cause impairment charges; investments required, or reduced demand for products, as a result of environmental rules and regulations; changes in tax, environmental and other laws and regulations (including alternative energy mandates); political and societal concerns about climate change that could result in changes to our business or increase expenditures, including litigation-related expenses; the operation, financing and distribution decisions of equity affiliates we do not control; and other economic, business, competitive and/or regulatory factors affecting Phillips 66’s businesses generally as set forth in our filings with the Securities and Exchange Commission. Phillips 66 is under no obligation (and expressly disclaims any such obligation) to update or alter its forward-looking statements, whether as a result of new information, future events or otherwise.

This news release also includes the term “mid-cycle adjusted EBITDA,” which is a forward-looking non-GAAP financial measure. EBITDA is defined as estimated net income plus estimated net interest expense, income taxes, and depreciation and amortization. Adjusted EBITDA is defined as estimated EBITDA plus the proportional share of selected equity affiliates’ estimated net interest expense, income taxes, and depreciation and amortization less the portion of estimated adjusted EBITDA attributable to noncontrolling interests. Net income is the most directly comparable GAAP financial measure for the consolidated company and income before income taxes is the most directly comparable GAAP financial measure for operating segments. Mid-cycle adjusted EBITDA is defined as the average adjusted EBITDA generated over a complete economic cycle. Mid-cycle adjusted EBITDA estimates or targets depend on future levels of revenues and expenses, including amounts that will be attributable to noncontrolling interests, which are not reasonably estimable at this time. Accordingly, we cannot provide a reconciliation of projected mid-cycle adjusted EBITDA to consolidated net income or segment income before income taxes without unreasonable effort.

References in the release to earnings refer to net income attributable to Phillips 66. References in the release to shareholder distributions refers to the sum of dividends paid to Phillips 66 stockholders and proceeds used by Phillips 66 to repurchase shares of its common stock. References to run-rate cost savings includes cost savings and references to run-rate synergies include costs savings and other benefits that will be reflected in the sales and other operating revenues, purchased crude oil and products costs, operating expenses, selling, general and administrative expenses and equity in earnings of affiliates lines on our consolidated statement of income when realized. References to run-rate sustaining capital savings includes savings that will be reflected in the capital expenditures and investments on our consolidated statement of cash flows when realized. References to run-rate savings represent the sum of run-rate cost savings and run-rate sustaining capital savings.
