Strategic Update

Phillips 66 Partners is expanding the Sweeny to Pasadena Pipeline by 80,000 barrels per day (BPD). In addition, products storage capacity will be increased by 300,000 barrels at the Pasadena Terminal and new connectivity will be added to third-party terminals. The project is expected to be completed in the second quarter of 2020.

The Partnership is constructing the 900,000-BPD Gray Oak Pipeline, which will provide crude oil transportation from the Permian and Eagle Ford to destinations in Corpus Christi and Freeport, including the Phillips 66 Sweeny Refinery. Phillips 66 Partners will have a 42.25 percent ownership in the pipeline, which is anticipated to be in service by the end of 2019.

The Gray Oak Pipeline will connect to multiple terminals in Corpus Christi, including the new South Texas Gateway Terminal under development by Buckeye Partners, L.P. The marine terminal will have two deepwater docks and planned storage capacity of 6.5 million to 7 million barrels. Phillips 66 Partners owns a 25 percent interest in the terminal, which is expected to start up by mid-2020.

The Sand Hills Pipeline expansion was completed in the fourth quarter of 2018, increasing the capacity to 485,000 BPD. The pipeline transports natural gas liquids (NGL) from the Permian and Eagle Ford to the Texas Gulf Coast and is owned one-third by the Partnership.

The Bayou Bridge Pipeline operates from Nederland, Texas, to Lake Charles, Louisiana. Commercial operations for the extension from Lake Charles to St. James, Louisiana, are expected to begin in March. Phillips 66 Partners owns a 40 percent interest in the joint venture.

The Partnership is constructing a 25,000-BPD isomerization unit at the Phillips 66 Lake Charles Refinery to increase production of higher-octane gasoline blend components. The project includes a long-term agreement with Phillips 66 for processing services with a minimum volume commitment. Completion is expected in the third quarter of 2019.

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

OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

This news release contains certain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, which are intended to be covered by the safe harbors created thereby. Words and phrases such as “is anticipated,” “is estimated,” “is expected,” “is planned,” “is scheduled,” “is targeted,” “believes,” “continues,” “intends,” “will,” “would,” “objectives,” “goals,” “projects,” “efforts,” “strategies” and similar expressions are used to identify such forward-looking statements. However, the absence of these words does not mean that a statement is not forward-looking. Forward-looking statements relating to Phillips 66 Partners’ operations (including joint venture operations) are based on management’s expectations, estimates and projections about the company, its interests and the energy industry in general on the date this news release was prepared. These statements are not guarantees of future performance and 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 the continued ability of Phillips 66 to satisfy its obligations under our commercial and other agreements; the volume of crude oil, refined petroleum products and NGL we or our joint ventures transport, fractionate, terminal and store; the tariff rates with respect to volumes that we transport through our regulated assets, which rates are subject to review and possible adjustment by federal and state regulators; fluctuations in the prices for crude oil, refined petroleum products and NGL; liabilities associated with the risks and operational hazards inherent in transporting, fractionating, terminaling and storing crude oil, refined petroleum products and NGL; potential liability from litigation or for remedial actions, including removal and reclamation obligations under environmental regulations; the failure to complete construction of announced and future capital projects in a timely manner and any cost overruns associated with such projects; and other economic, business, competitive and/or regulatory factors affecting Phillips 66 Partners’ businesses generally as set forth in our filings with the Securities and Exchange Commission. Phillips 66 Partners 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.

Use of Non-GAAP Financial Information — This news release includes the terms “EBITDA,” “adjusted EBITDA,” “distributable cash flow,” and “coverage ratio.” These are non-GAAP financial measures. EBITDA and adjusted EBITDA are included to help facilitate comparisons of operating performance of the Partnership with other companies in our industry. EBITDA and distributable cash flow help facilitate an assessment of our ability to generate sufficient cash flow to make distributions to our partners. We believe that the presentation of EBITDA, adjusted EBITDA and distributable cash flow provides useful information to investors in assessing our financial condition and results of operations. Our coverage ratio is calculated as distributable cash flow divided by total cash distributions and is included to help indicate the Partnership’s ability to pay cash distributions from current earnings. The GAAP performance measure most directly comparable to EBITDA and adjusted EBITDA is net income. The GAAP liquidity measure most comparable to EBITDA and distributable cash flow is net cash provided by operating activities. The GAAP financial measure most comparable to our coverage ratio is calculated as net cash provided by operating activities divided by total cash distributions. These non-GAAP financial measures should not be considered as alternatives to GAAP net income or net cash provided by operating activities. They have important limitations as analytical tools because they exclude some but not all items that affect net income and net cash provided by operating activities. They should not be considered in isolation or as substitutes for analysis of our results as reported under GAAP. Additionally, because EBITDA, adjusted EBITDA and distributable cash flow may be defined differently by other companies in our industry, our definition of EBITDA, adjusted EBITDA and distributable cash flow may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.

A reconciliation of current quarter adjusted EBITDA to net income accompanies this release. The disaggregation of capital spending between expansion/growth and maintenance is not a distinction recognized under GAAP. We provide such disaggregation because the Partnership will generally fund maintenance capital spending with cash from operating activities and fund expansion/growth capital spending with financing activities. We believe this is an important distinction in our liquidity profile.

References in the release to earnings and capital spending refer to net income and capital spending attributable to the Partnership, respectively. References to EBITDA refer to earnings before interest, income taxes, depreciation and amortization.

Factors Affecting Comparability

The following tables present our financial results and operating data for each quarterly period of the current and prior fiscal years. During the periods covered by this report, we acquired businesses from Phillips 66 that were considered transfers of businesses between entities under common control, which requires them to be accounted for as if the transfers had occurred at the beginning of the period of transfer, with financial statements for prior periods retrospectively adjusted to furnish comparative information. Accordingly, the consolidated financial and operating information included in the following tables has been retrospectively adjusted to include the historical financial and operating results of these acquired businesses prior to the effective date of acquisition. We refer to the results of these pre-acquisition periods as those of our “Predecessors” in the tables below. Tables labeled “Phillips 66 Partners LP” exclude Predecessors, while tables labeled “Consolidated” include Predecessors. The statements of income provided on pages 1 through 3 are designed to enable users to evaluate the financial effect of these business combinations in accordance with Accounting Standard Codification 805-10-50-1.
