SAN ANTONIO - November 8, 2017 - Andeavor Logistics LP ANDX today reported third quarter net earnings of $97 million, or $0.90 per diluted common limited partner unit compared to $81 million, or $0.46 per diluted common limited partner unit a year ago. EBITDA for the third quarter 2017 was $216 million compared to $177 million last year. Net earnings and EBITDA for the third quarter 2017 included a $19 million environmental accrual and $4 million of transaction costs related to the Western Refining Logistics, LP (WNRL) acquisition and IDR Buy-In. As the WNRL acquisition and IDR Buy-In occurred prior to the record date for Andeavor Logistics, distribution coverage for the third quarter 2017 reflects the impact of the units issued on October 30, 2017 while using standalone Andeavor Logistics distributable cash flow as reported on September 30, 2017.

(b)   For more information on EBITDA, Segment EBITDA, Distributable Cash Flow, Pro Forma Distributable Cash Flow, Pro Forma Distributions, Distribution Coverage Ratio, and Pro Forma Distribution Coverage Ratio, see "Non-GAAP Measures".

"Our performance during the quarter was strong, driven by record volume growth in terminalling and volume growth and increased throughput in gas gathering and processing," said Greg Goff, Chairman and Chief Executive Officer of Andeavor Logistics' general partner. "Including the Anacortes Logistics Assets drop down, we also achieved a significant milestone this quarter in reaching our run rate target of $525 million of annual net earnings or $1 billion of annual EBITDA at Andeavor Logistics."

"Building on our strong performance in the third quarter, the WNRL acquisition and the Anacortes Logistics Assets drop down, we are confident in our ability to achieve our target of $625 to $725 million of annual net earnings and $1.2 to $1.3 billion of annual EBITDA for 2018. In addition, we expect the IDR Buy-In and investment grade credit rating will drive a significant reduction in our cost of capital which positions us well to achieve our growth investment expectations of $1 billion annually," added Goff.

SEGMENT RESULTS
TERMINALLING AND TRANSPORTATION. Terminalling and Transportation segment operating income increased to $110 million for the third quarter 2017 from $80 million last year, and segment EBITDA increased to $137 million from $100 million a year ago. Terminalling volumes improved to 1,111 thousand barrels per day from 1,038 thousand barrels per day a year ago. The increase in volumes was primarily driven by strong operational performance and robust summer demand for refined products. The Anacortes Crude Rail Offloading Facility (CROF) experienced 12 thousand barrels per day higher volumes sequentially from the second quarter 2017 driven by crude oil and feedstock movements from the Bakken. The year-over-year increase in volumes was also attributable to contributions from the drop downs completed in 2016. Transportation pipeline volumes of 907 thousand barrels per day remained relatively flat compared to 908 thousand barrels per day in 2016.

GATHERING AND PROCESSING. Gathering and Processing segment operating income was $47 million for the third quarter 2017 compared to $54 million last year. Segment EBITDA increased to $85 million from $84 million a year ago. Results included a $19 million environmental accrual related to the expected final remediation costs for the 2013 crude oil pipeline release at Tioga, North Dakota. Crude oil and water gathering throughput for the third quarter 2017 increased to 238 thousand barrels per day from 206 thousand barrels per day in 2016. The increase in volumes was primarily attributable to contributions from the North Dakota Gathering and Processing Assets acquisition completed in early 2017. The average crude oil and water revenue per barrel improved to $1.96 sequentially from $1.55 in the second quarter 2017, benefiting from Andeavor's Mandan Refinery returning to full operations, resulting in longer haul crude oil movements, and increased production in crude oil and water gathering in the Belfield region of the Bakken.

Gas gathering and processing throughput for the third quarter 2017 increased to 961 thousand MMBtu per day from 885 thousand MMBtu per day a year ago, due to contributions from the North Dakota Gathering and Processing Assets acquisition. Production of Natural Gas Liquids either under Keep Whole or Percent of Proceeds arrangements increased to 7.0 thousand barrels per day in the third quarter 2017 from 6.8 thousand barrels per day last year. The increase in volumes was primarily driven by the North Dakota Gathering and Processing Assets acquisition.

BALANCE SHEET AND CASH FLOW
Net cash from operating activities was $195 million in the third quarter 2017 compared to $172 million in 2016. Distributable cash flow for the third quarter increased to $148 million from $133 million last year. Pro forma distributable cash flow was $152 million for the third quarter, which excludes $4 million of transaction costs related to the acquisition of WNRL and the IDR Buy-In. The Company ended the third quarter 2017 with $16 million of cash. Andeavor Logistics has approximately $1.6 billion of availability under its revolving credit facilities.

Net capital expenditures for the third quarter 2017 were $44 million, which included $30 million of growth capital and $14 million of net maintenance capital. Andeavor Logistics now expects net capital expenditures for 2017 to be approximately $200 million, including $145 million of growth capital and $55 million of net maintenance capital. The revised capital expenditure estimate reflects changes in the Company's funding strategy for the Los Angeles Pipeline Interconnect System and the Conan Crude Oil Gathering Pipeline System (the Conan System). Andeavor anticipates transferring the Los Angeles Pipeline Interconnect System and the Conan System to Andeavor Logistics at cost when the projects are complete versus Andeavor Logistics making progress payments as capital expenditures during project construction. This change does not have any impact on Andeavor Logistics' 2018 expected growth plans or EBITDA targets.

On October 18, 2017, the Company announced its quarterly cash distribution of $0.9852 per limited partnership unit or $3.94 on an annualized basis. The declared distribution represents a 13% increase over the third quarter 2016 distribution of $0.875 per limited partner unit paid on November 14, 2016. This also represents the 26th consecutive quarterly increase. Due to the timing of closing the WNRL acquisition and the IDR Buy-In transaction, third quarter distributions will be paid on units issued for these transactions. WNRL unitholders will not receive a separate quarterly cash distribution from WNRL. The distribution coverage ratio was 0.74x for the third quarter and 0.98x year-to-date 2017. Pro forma distribution coverage ratio, which excludes the $4 million of transaction costs and assumes the acquisition of WNRL and IDR Buy-In occurred after the record date for the third quarter 2017 distribution, was 1.10x for the third quarter and 1.13x year-to-date 2017.

STRATEGIC UPDATE
COMPLETION OF MERGER AND IDR BUY-IN. On October 30, 2017, Andeavor Logistics completed its $1.7 billion acquisition of Western Refining Logistics. Immediately following the closing of the WNRL acquisition, Andeavor ANDV and Andeavor Logistics completed the IDR Buy-In transaction whereby Andeavor Logistics issued 78.0 million ANDX common units to Andeavor in exchange for the cancellation of Andeavor Logistics' IDRs and the conversion of its economic general partner interest into a non-economic general partner interest. The total value of the IDR Buy-In represents $3.6 billion in value based on Andeavor Logistics' closing unit price of $45.90 on October 30, 2017. The Company remains committed to achieving its target $625 to $725 million of annual net earnings and $1.2 to $1.3 billion of annual EBITDA for 2018, annual distribution growth of 6% or greater, distribution coverage ratio of approximately 1.1x and debt-to-EBITDA at or below 4.0x.

INVESTMENT GRADE CREDIT RATING ACHIEVED. On October 31, 2017, S&P Global Ratings raised Andeavor Logistics' corporate credit and senior unsecured issue ratings to "BBB-" with a stable outlook from "BB+". In February 2017, Fitch Ratings assigned a first-time Long-Term Issuer Default Rating of BBB- to Andeavor Logistics, marking the Company's inaugural investment grade credit rating. As a result of Andeavor Logistics achieving a "BBB-" credit rating at both S&P and Fitch, the Company's outstanding unsecured bond securities now meet the criteria to be included in the investment grade Bloomberg Barclays Global Aggregate and ICE BofAML Global Bond Indices. Andeavor Logistics is well positioned to enhance its existing capital structure and meet future financing needs at attractive rates with longer maturities in a more liquid market. Additionally, on October 26, 2017, Moody's Investors Service upgraded Andeavor Logistics' Corporate Family Rating to "Ba1" with a positive outlook from "Ba2".

DROP DOWN OF ANACORTES LOGISTICS ASSETS. Andeavor Logistics today announced it has acquired logistics assets located in Anacortes, Washington from Andeavor for total consideration of $445 million. The Anacortes Logistics Assets include 3.9 million barrels of crude oil, feedstock and refined products storage at Andeavor's Anacortes Refinery, the Anacortes marine terminal with approximately 73 thousand barrels per day of feedstock and refined product throughput, a manifest rail facility with approximately 4 thousand barrels of throughput and crude oil and refined products pipelines with approximately 111 thousand barrels per day of throughput combined.

The Anacortes Logistics Assets are expected to provide annual net earnings of $30 to $35 million and annual EBITDA of $50 to $55 million. This represents a multiple of approximately 8.5 times annual EBITDA, and the transaction is expected to be immediately accretive to unitholders. In connection with the acquisition, Andeavor and Andeavor Logistics entered into long-term, fee-based agreements which are expected to provide stable cash flows to Andeavor Logistics. Andeavor Logistics paid $445 million, including $400 million of cash financed with borrowings on Andeavor Logistics revolving credit facilities and approximately $45 million in common units issued to Andeavor for the drop down. The equity consideration was based on the average daily closing price of Andeavor Logistics' common units for the 10 trading days prior to closing, or $45.37 per unit in the form of 980,802 common units.

CONAN CRUDE OIL GATHERING PIPELINE SYSTEM. During the quarter, Andeavor announced that it received sufficient commitments from third party shippers to warrant construction of the Conan Crude Oil Gathering Pipeline system in the Delaware Basin. The Conan Crude Oil Gathering Pipeline system will be approximately 130 miles in length and transport crude oil from origins in Lea County, New Mexico and Loving County, Texas to a terminal to be constructed in Loving County, Texas, where the gathering system interconnects with long-haul pipeline carriers. The first phase of the Conan Crude Oil Gathering Pipeline system will provide capacity of approximately 250,000 barrels per day. Future phases of the system may expand capacity up to 500,000 barrels per day.

The system is under construction and is expected to begin commercial service in mid-2018. The estimated capital investment for the first phase of the gathering system is approximately $225 million of which $75 million is expected to be spent in 2017. This project is expected to be transferred to Andeavor Logistics at cost upon completion in 2018.

FOURTH QUARTER 2017 GUIDANCE (Unaudited)

NON-GAAP MEASURES

As a supplement to our financial information presented in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"), our management uses certain "non-GAAP" measures to analyze our results of operations, assess internal performance against budgeted and forecasted amounts and evaluate future impacts to our financial performance as a result of capital investments, acquisitions, divestitures and other strategic projects. These measures are important factors in assessing our operating results and profitability and include:

• Financial non-GAAP measures:
  • EBITDA-U.S. GAAP-based net earnings before interest, income taxes, and depreciation and amortization expense; and
  • Segment EBITDA-a segment's U.S. GAAP-based operating income before depreciation and amortization expense plus equity in earnings (loss) of equity method investments and other income (expense), net.
     
• Liquidity non-GAAP measures:
  • Distributable Cash Flow-U.S. GAAP-based net cash flow from operating activities plus or minus changes in working capital, amounts spent on maintenance capital net of reimbursements and other adjustments not expected to settle in cash;
  • Pro Forma Distributable Cash Flow-Distributable Cash Flow plus or minus adjustments for the WNRL Merger;
  • Pro Forma Distributions-Distributions expected to be paid adjusted for common units issued in connection with the WNRL Merger and the IDR/GP Buy-in;
  • Distribution Coverage Ratio-Distributable Cash Flow divided by total distributions to be paid for the reporting period; and
  • Pro Forma Distribution Coverage Ratio-Pro Forma Distributable Cash Flow divided by Pro Forma Distributions.
     
• Operating performance non-GAAP measure:
  • Average Margin on Natural Gas Liquids ("NGLs") Sales per Barrel-NGL sales revenues minus amounts recognized as NGL expense divided by our NGL sales volumes in barrels.

We present these measures because we believe they may help investors, analysts, lenders and ratings agencies analyze our results of operations and liquidity in conjunction with our U.S. GAAP results, including but not limited to:

• our operating performance as compared to other publicly traded partnerships in the midstream energy industry, without regard to historical cost basis or financing methods;
• the ability of our assets to generate sufficient cash flow to make distributions to our unitholders;
• our ability to incur and service debt and fund capital expenditures; and
• the viability of acquisitions and other capital expenditure projects and the returns on investment of various investment opportunities.

Management also uses these measures to assess internal performance, and we believe they may provide meaningful supplemental information to the users of our financial statements. Non-GAAP measures have important limitations as analytical tools, because they exclude some, but not all, items that affect net earnings, operating income and net cash from operating activities. These measures should not be considered substitutes for their most directly comparable U.S. GAAP financial measures. See  "Reconciliation of Amounts Reported Under U.S. GAAP," "Segment Reconciliation of Amounts Reported Under U.S. GAAP," "Average Margin on NGL Sales per Barrel" and "Reconciliation of EBITDA to Amounts Under U.S. GAAP" for reconciliations between non-GAAP measures and their most directly comparable U.S. GAAP measures.

ITEMS IMPACTING COMPARABILITY

The Partnership's results of operations may not be comparable to the historical results of operations for the reasons described below.

ACQUISITIONS AND MERGERS.  Effective October 30, 2017, Andeavor Logistics closed its merger with Western Refining Logistics, LP ("WNRL") (the "WNRL Merger") exchanging all outstanding common units of WNRL with units of Andeavor Logistics, representing an equity value of $1.7 billion. WNRL public unitholders received 0.5233 units of Andeavor Logistics for each WNRL unit held while Andeavor effectively received 0.4639 units as certain units held by Andeavor's subsidiaries were canceled in the transaction. The combined effective exchange ratio for the WNRL Merger was 0.4921 units of Andeavor Logistics for every unit of WNRL. Concurrently with the closing of the WNRL Merger, WNRL GP Merger Sub LLC, a direct, wholly-owned subsidiary of Andeavor Logistics merged with and into Western Refining Logistics GP, LLC ("WNRL General Partner") with WNRL General Partner being the surviving entity and becoming a wholly-owned subsidiary of Andeavor Logistics.

The closing of the WNRL Merger was conditioned upon, among other things, the adoption and effectiveness of the Second Amended and Restated Agreement of Limited Partnership of Andeavor Logistics LP, pursuant to which, simultaneously with the closing of the WNRL Merger: (i) the incentive distribution rights in Andeavor Logistics (the "IDRs") held by Tesoro Logistics GP, LLC ("TLGP"), our general partner, were canceled (the "IDR Exchange"), (ii) the general partner interests in Andeavor Logistics held by TLGP were converted into a non-economic general partner interest in Andeavor Logistics (together with the IDR Exchange, the "IDR/GP Transaction"), and (iii) Andeavor and its affiliates, including TLGP, agreed to increase and extend existing waivers on distributions to Andeavor and its affiliates by $60 million to an aggregate of $160 million between 2017 and 2019. As consideration for the IDR/GP Transaction, TLGP was issued 78.0 million common units in Andeavor Logistics simultaneously with the closing of the WNRL Merger.

On January 1, 2017, the Partnership acquired crude oil, natural gas and produced water gathering systems and two natural gas processing facilities (the "North Dakota Gathering and Processing Assets"). The North Dakota Gathering and Processing Assets include over 650 miles of crude oil, natural gas, and produced water gathering pipelines, 170 MMcf per day of natural gas processing and 18,700 barrels per day of fractionation capacity in the Sanish and Pronghorn fields of the Williston Basin in North Dakota. The operating results for this acquisition are reflected in our Gathering and Processing segment.

On November 21, 2016, we acquired certain terminalling and storage assets located in Martinez, California (the "Northern California Terminalling and Storage Assets") purchased from subsidiaries of Andeavor. The Northern California Terminalling and Storage Assets include 5.8 million barrels of crude oil, feedstock, and refined product storage capacity at Andeavor's Martinez Refinery along with the Avon marine terminal capable of handling 80,000 bpd of feedstock and refined product throughput. Additionally, on July 1 and September 16, 2016, the Partnership purchased certain terminalling and storage assets in Anchorage, Fairbanks and at Andeavor's Kenai Refinery (together, the "Alaska Storage and Terminalling Assets") owned by Andeavor. The storage assets include tankage with a shell capacity of approximately 3.5 million barrels and ancillary facilities used for the operations at Andeavor's Kenai Refinery. The refined product terminals are located in Anchorage and Fairbanks. The operating results for these acquisitions from Andeavor are reflected in our Terminalling and Transportation segment.

PREDECESSOR IMPACTS.  Our financial information includes the historical results of the acquired assets from Andeavor ("Predecessors") and the results of Andeavor Logistics for all periods presented. The financial statements of our Predecessors have been prepared from the separate records maintained by Andeavor and may not necessarily be indicative of the conditions that would have existed or the results of operations if our Predecessors had been operated as an unaffiliated entity.

CHANGE IN SEGMENT PRESENTATION.  We changed our operating segment presentation in the first quarter of 2017 to reflect our expanded gathering and processing assets and operations and how our chief operating decision maker manages our business. With the completion of the North Dakota Gathering and Processing Assets acquisition on January 1, 2017, our gathering and processing assets and operations expanded significantly and enhanced our ability to offer integrated gathering and processing services to our customers. Given the business's focus on providing integrated services along with the revised reporting structure implemented by management to assess performance and make resource allocation decisions, we determined our operating segments, which are the same for reporting purposes, are the (i) Gathering and Processing segment and (ii) Terminalling and Transportation segment. Comparable prior period information for the newly presented Gathering and Processing segment has been recast to reflect our current presentation. No changes were deemed necessary to our Terminalling and Transportation segment. In addition, management revised its methodology for the allocation of corporate general and administrative expenses. Comparable prior period segment information has been recast to reflect our revised allocation methodology.

SELECTED OPERATING SEGMENT DATA (Unaudited)
(In millions, except volumes, margin per barrel, revenue per barrel and revenue per MMBtu)

(j)     For the three months ended September 30, 2017, Andeavor Logistics had 21.1 Mbpd of gross natural gas liquids ("NGL") sales under percent of proceeds ("POP") and keep-whole arrangements, of which Andeavor Logistics retained 7.0 Mbpd. For the nine months ended September 30, 2017, Andeavor Logistics had 21.0 Mbpd of gross NGL sales under POP and keep-whole arrangements, of which Andeavor Logistics retained 7.3 Mbpd. The difference between gross sales barrels and barrels retained is reflected in NGL expense resulting from the gross presentation required for the POP arrangements associated with the North Dakota Gathering and Processing Assets.
(k)   Included in NGL expense for the nine months ended September 30, 2017 were approximately $2 million of cost of sales related to crude oil volumes obtained in connection with the North Dakota Gathering and Processing Assets acquisition, respectively. There were no crude oil volumes included in NGL expense for the three months ended September 30, 2017. The corresponding revenues were recognized in pass-thru and other revenue. As such, the calculation of the average margin on NGL sales per barrel excludes this amount.
(l)     Operating expenses include an imbalance settlement gain of $1 million and $4 million for the three and nine months ended September 30, 2017, respectively and $1 million and $2 million for the three and nine months ended September 30, 2016, respectively.

(m)  Volumes represent barrels sold under our keep-whole arrangements, net barrels retained under our POP arrangements and other associated products.
