Andeavor Logistics LP Reports First-Quarter 2019 Results


•	Reported first-quarter net earnings of $157 million and EBITDA of $319 million, which provided 1.06x distribution coverage and resulted in 3.9x leverage


•	Terminalling and Transportation segment operating income of $152 million and EBITDA of $191 million driven by drop downs and strong pipeline transportation volumes


•	Gathering and Processing segment operating income of $63 million and EBITDA of $129 million impacted by lower Rockies volumes, offset by Permian crude oil and Bakken natural gas volume growth


•	Reported net cash from operating activities of $219 million and DCF attributable to common unitholders of $255 million


•	Announced agreement to be acquired by MPLX

FINDLAY, Ohio, May 8, 2019 - Andeavor Logistics LP (NYSE: ANDX) today reported first-quarter 2019 net earnings of $157 million, compared with $131 million in 2018. Earnings before interest, taxes, depreciation and amortization (EBITDA) was $319 million, compared with $275 million in first-quarter 2018. The increase in earnings and EBITDA was driven by the 2018 Drop Down completed in August 2018, which contributed $33 million of net earnings and $47 million of EBITDA in 2019, and the SLC Core Pipeline System acquisition completed in May 2018. Terminalling and Transportation reported segment operating income of $152 million and segment EBITDA of $191 million for the quarter, up $48 million for both, respectively, on a year-over-year basis. Gathering and Processing reported segment operating income of $63 million and segment EBITDA of $129 million for the quarter, down $14 million and $4 million, respectively, versus the first-quarter of last year.

The company also announced that MPLX LP (NYSE: MPLX) and Andeavor Logistics have entered into a definitive merger agreement whereby MPLX will acquire ANDX in a unit-for-unit exchange. “This merger creates a leading, large-scale, diversified midstream company anchored by fee-based cash flows,” said Gary R. Heminger, chairman and chief executive officer. “The combined entity will have an expanded geographic footprint with enhanced long-term growth opportunities. We are confident about the midstream growth and value-creation opportunities that exist across this combined platform in the best basins in the U.S.

“Andeavor Logistics’ first-quarter results increased year-over-year, driven by the 2018 Drop Down, higher pipeline transportation volumes, and increased crude oil volumes in the Permian,” added Heminger. “The positives in first quarter offset headwinds associated with lower Rockies natural gas gathering and processing volumes, lower NGL sales from ethane rejection, and extreme winter weather impacting Bakken crude oil gathering volumes.

“Looking forward, we expect solid results in the Terminalling and Transportation segment, driven by the 2018 Drop Down and seasonally strong demand through our terminal and pipeline assets,” Heminger continued. “We also expect strong results in the Gathering and Processing

segment from continued growth in Permian crude, Bakken gas, and full operations on our NGL Logistics Hub project.”

The company generated $219 million in net cash from operating activities and distributable cash flow (DCF) attributable to common unitholders of $255 million during the quarter. On April 29, 2019, Andeavor Logistics announced a quarterly cash distribution of $1.03 per limited partnership unit, or $4.12 on an annualized basis, which was flat with the prior quarter, and finished the quarter with coverage of 1.06x and leverage of 3.9x.

Segment Results

Terminalling and Transportation

Terminalling and Transportation segment operating income was $152 million for the first-quarter 2019, an increase of $48 million from the prior year, and segment EBITDA was $191 million, an increase of $48 million from the prior year. The year-over-year increase was primarily attributable to contributions from the 2018 Drop Down, stronger year-over-year pipeline transportation volumes associated with lower refinery turnaround activity, and the SLC Core Pipeline System acquisition. During the quarter, the 2018 Drop Down contributed $19 million of segment operating income and $26 million of segment EBITDA.

Gathering and Processing

Gathering and Processing segment operating income was $63 million for the first-quarter 2019, a decrease of $14 million from the prior year, and segment EBITDA was $129 million, a decrease of $4 million from the prior year. The decrease was primarily attributable to lower natural gas gathering, processing, and NGL sales volumes in the Rockies as well as an expiration of a natural gas gathering contract in the Rockies. This was partially offset by Permian Basin crude oil volume growth and higher natural gas gathering and processing volumes in the Bakken from the expanded capacity at the Robinson Lake processing facility. Results were also impacted by a non-cash accrual due to a legal reserve associated with an ongoing contract dispute. During the quarter, the 2018 Drop Down contributed $17 million of segment operating income and $21 million of segment EBITDA.

Wholesale

Wholesale segment operating income was $5 million for the first-quarter 2019, an increase of $1 million from the prior year, and segment EBITDA for the first-quarter 2019 was $8 million, an increase of $1 million from the prior year. The slight year-over-year increase was driven by higher volumes and a favorable wholesale margin environment.

Balance Sheet and Cash Flow

Net cash from operating activities was $219 million in the first-quarter 2019, and distributable cash flow attributable to common unitholders for the first-quarter was $255 million. As of March 31, 2019, Andeavor Logistics had $29 million of cash and $1.2 billion of availability under its credit facilities and intercompany loan with Marathon Petroleum Corporation (NYSE: MPC). Total debt of $5.2 billion resulted in a leverage ratio of 3.9x at March 31, 2019.

Net capital expenditures for the first-quarter 2019 were $106 million, which included $100 million of net growth investments and $6 million of net maintenance capital.

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;


◦	Distributable Cash Flow - U.S. GAAP-based net cash flow from EBITDA adjusted for amounts spent on maintenance capital net of reimbursements and other adjustments;


◦	Pro forma LTM EBITDA - Last twelve months (“LTM”) of our EBITDA adjusted for pro forma contributions from acquisitions; 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 adjusted for changes in working capital, amounts spent on maintenance capital net of reimbursements and other adjustments not expected to settle in cash;


◦	Distributable Cash Flow Attributable to Common Unitholders - Distributable Cash Flow minus distributions associated with the preferred units;


◦	Distribution Coverage Ratio - Distributable Cash Flow Attributable to Common Unitholders divided by total distributions to be paid to common unitholders for the reporting period; and


◦	Leverage Ratio - Total debt divided by Pro forma LTM EBITDA.


•	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,” and “Average Margin on NGL Sales per Barrel” 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

Other than certain assets acquired from the 2018 Drop Down, our Predecessors did not record revenues with Andeavor and our Predecessors recorded general and administrative expenses and financed operations differently than the Partnership. As previously mentioned, on August 6, 2018, we completed the 2018 Drop Down for total consideration of $1.55 billion. As an entity under common control with Andeavor, who merged with and became a wholly-owned subsidiary of MPC effective October 1,

2018, we accounted for the transfers of businesses as if the transfer occurred at the beginning of the period, and prior periods are retrospectively adjusted to furnish comparative information. Accordingly, the accompanying results of operations have been retrospectively adjusted to include the historical results of the assets acquired prior to the effective date of the acquisition.

•	Average margin on NGL sales per barrel—calculated as the difference between the NGL sales revenues and the amounts recognized as NGL expense divided by our NGL sales volumes presented in Mbpd multiplied by 1,000 and multiplied by the number of days in the period as outlined above;


•	Average gas gathering and processing revenue per MMBtu—calculated as total gathering and processing fee-based revenue divided by gas gathering throughput presented in thousands of MMBtu per day (“MMBtu/d”) multiplied by 1,000 and multiplied by the number of days in the period as outlined above;


•	Average crude oil and water gathering revenue per barrel—calculated as total crude oil and water gathering fee-based revenue divided by crude oil and water gathering throughput presented in Mbpd multiplied by 1,000 and multiplied by the number of days in the period as outlined above; and


•	Wholesale fuel sales per gallon—calculated as wholesale fuel revenues divided by our total wholesale fuel sales volume in gallons.

There are a variety of ways to calculate these measures; other companies may calculate these in a different way. Amounts may not recalculate due to rounding of dollar and volume information.
