“During the quarter, we demonstrated our ability to grow the business through strong operational execution, organic growth from our existing assets and strategic acquisitions with the addition of the Alaska Storage and Terminalling assets," said Greg Goff, Chairman and Chief Executive Officer of TLLP’s general partner. “Although we continue to experience headwinds in the Gathering and Processing segments of our business, we had record throughput and revenue in our Terminalling and Transportation business. We remain committed to achieving our target of $635 million of annual net earnings and $1 billion of annual EBITDA in 2017.”

Net cash from operating activities was $176 million, up $39 million, or 28%, during 2016 compared to 2015. Distributable cash flow for the third quarter was $133 million, up $18 million, or 16%, from the third quarter 2015. On October 19, 2016, the Company announced its quarterly cash distribution of $0.875 per limited partner unit or $3.50 on an annualized basis. The declared distribution represents a 17% increase over the third quarter 2015 distribution of $0.75 per limited partner unit. This also represents the 22nd consecutive quarterly increase of approximately 4% or more. The distribution coverage ratio was 1.02 times and the Company ended the quarter with approximately $500 million of cash. Lower coverage primarily reflects distributions related to units issued in the June offering as well as units issued to Tesoro in connection with the acquisition of the Alaska Storage and Terminalling Assets. Coverage for the trailing twelve month period was 1.10x.

SEGMENT RESULTS

GATHERING. The Gathering segment generated $82 million of revenue in the third quarter compared to $87 million in the third quarter 2015. On a year-over-year basis, crude oil gathering volumes grew by 7 thousand barrels per day to 206 thousand barrels per day due to higher takeaway pipeline demand. Natural gas gathering volumes were 887 thousand MMBtu per day in the third quarter 2016 compared to 1,115 thousand MMBtu per day in 2015. The third quarter of 2015 included 142 thousand MMBtu per day of third-party throughput attributable to the Rendezvous Gas Services, L.L.C (“RGS”) joint venture prior to its deconsolidation. Year-over-year natural gas gathering volumes were also impacted by reduced customer activity due to the lower commodity price environment. However, natural gas gathering volumes improved sequentially due to increased drilling and completion activity. Segment operating income for the third quarter 2016 was $31 million compared to $42 million last year. Segment EBITDA totaled $50 million in the third quarter compared to $60 million in the third quarter 2015. The decline is primarily attributable to the exclusion of RGS from the 2016 quarter’s results, as well as lower volumes.

PROCESSING. The Processing segment generated $69 million of revenue in the third quarter, compared to $71 million a year ago. NGL processing volumes were 6.7 thousand barrels per day compared to 7.8 thousand barrels per day last year and fee-based processing volumes were 625 thousand MMBtu per day compared to 767 thousand MMBtu per day a year ago. Year-over-year volume declines were due to reduced natural gas production. Additionally, keep-whole processing volumes were impacted by a customer compression upset that curtailed their gas flow into the system for most of the quarter. Segment operating income was $29 million and segment EBITDA was $40 million in the third quarter and both were flat versus last year.

TERMINALLING AND TRANSPORTATION. The Terminalling and Transportation segment generated record revenue of $157 million in the third quarter, up 27% from $124 million in the third quarter 2015. Terminalling revenues were up primarily reflecting storage assets acquired as part of the Los Angeles Storage and Pipeline Assets acquisition in the fourth quarter 2015 and the Alaska Storage and Terminalling Assets acquisition this quarter. Additionally, Terminalling volumes increased to a record 1.02 million barrels per day from 964 thousand barrels per day and Transportation pipeline volumes increased to a record 908 thousand barrels per day from 838 thousand barrels per day a year ago. The record results in the quarter were driven by optimization, organic growth and the strategic acquisitions of the Los Angeles and Alaska assets. Segment operating income totaled $85 million, up 67% from third quarter 2015. Segment EBITDA totaled $103 million in the third quarter, up 49% from last year.

CAPITAL EXPENDITURES

Net capital expenditures for the third quarter totaled $37 million, reflecting $26 million of growth capital, and net spending of $11 million for maintenance capital.

STRATEGIC UPDATE

TLLP continues to execute its strategy to grow the business through asset optimization and organic investments, as well as strategic acquisitions from Tesoro and third parties. In the third quarter, TLLP made progress on several organic growth projects in the High Plains gathering system and Uinta basin, as well as enhancing the capabilities at several terminals. Additionally, the Company began construction on a natural gas gathering compression project in the Vermillion basin in Wyoming, which is anticipated to be in-service in the third quarter 2017. Additionally, on July 1, 2016 and September 16, 2016, TLLP acquired storage and terminalling assets in Alaska from Tesoro for a total consideration of $444 million. The combined assets are expected to provide annual net earnings of $36 million and annual EBITDA of $51 million. Regarding TLLP’s credit rating, on October 14, 2016, S&P Global Ratings upgraded TLLP's credit rating to BB+ with a stable outlook from the previous rating of BB. This rating is now the same rating as that of Tesoro and one level below investment grade.

OUTLOOK

The Company expects that Tesoro will offer the Northern California Terminalling and Storage Assets for acquisition in the fourth quarter 2016, which is expected to add an estimated $28 to $33 million of annual net earnings and $45 to $50 million of annual EBITDA. The Company expects full year 2016 net earnings of $345 to $365 million and EBITDA of $710 to $730 million, which includes contributions from the Alaska Storage and Terminalling Assets completed in the third quarter, but excludes any contributions from the potential acquisition of the Northern California Terminalling and Storage Assets. TLLP expects to achieve 17% annual distribution growth in 2016 while maintaining annual distribution coverage of 1.1 times. TLLP has reduced its 2016 capital expenditure guidance to $170 million, net of reimbursements from Tesoro, to reflect changes in producer activity, cost savings on projects currently underway and timing of project spend.

ITEMS IMPACTING COMPARABILITY

The Partnership’s future results of operations may not be comparable to the historical results of operations of the acquired assets from Tesoro (“Predecessor”) for the reasons described below.

On November 12, 2015, the Partnership purchased crude oil and refined product storage and pipeline assets in Los Angeles, California (the "LA Storage and Handling Assets") owned by subsidiaries of Tesoro Corporation for a total consideration of $500 million. The Partnership acquired 97 crude oil, feedstock, and refined product storage tanks with combined capacity of 6.6 million barrels and a 50% interest in a 16-mile pipeline that transports jet fuel from Tesoro’s Los Angeles refinery to the Los Angeles International Airport. The acquisition price of $500 million included cash of approximately $250 million and the issuance of common and general partner units to Tesoro, valued at approximately $250 million.

On July 1 and September 16, 2016, the Partnership purchased certain terminalling and storage assets in Anchorage, Fairbanks and at Tesoro’s Kenai Refinery (together, the “Alaska Storage and Terminalling Assets”) owned by Tesoro for total consideration of $444 million. The storage assets include tankage with a shell capacity of approximately 3.5 million barrels and ancillary facilities used for the operations at Tesoro’s Kenai Refinery. The refined product terminals are located in Anchorage and Fairbanks.

We have a 78% interest in Rendezvous Gas Services, L.L.C. (“RGS”), which owns and operates the infrastructure that transports gas from certain fields to several re-delivery points in southwestern Wyoming, including natural gas processing facilities that are owned by us or a third party. Prior to 2016, we consolidated RGS; however, upon performing the required reassessments in conjunction with our adoption of ASU 2015-02 as of January 1, 2016, we determined RGS represents a variable interest entity to us for which we are not the primary beneficiary resulting in the deconsolidation of RGS and the reporting of RGS as an equity method investment. We recognized an increase of $295 million to equity method investments as of January 1, 2016 as a result of the deconsolidation in addition to a cumulative effect reduction to opening equity of $2 million related to the difference in earnings under the equity method of accounting in prior periods.

Our financial information includes the historical results of our Predecessor and the results of TLLP for all periods presented. The financial statements of our Predecessor have been prepared from the separate records maintained by Tesoro and may not necessarily be indicative of the conditions that would have existed or the results of operations if our Predecessor had been operated as an unaffiliated entity.

NON-GAAP MEASURES

Our management uses certain performance and liquidity non-GAAP measures to analyze operating segment performance. Our management also uses additional measures that are known as “non-GAAP” financial measures in its evaluation of past performance and prospects for the future to supplement our financial information presented in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). These measures are important factors in assessing our operating results and profitability and include the following:

• Financial non-GAAP measures:

◦ U.S. GAAP-based net earnings before interest, income taxes, and depreciation and amortization expenses (“EBITDA”); and

◦ Segment EBITDA is defined as a segment’s U.S. GAAP-based operating income before depreciation and amortization expenses plus equity in earnings (loss) of equity method investments and other income (expense), net.

• Liquidity non-GAAP measures:

◦ Distributable Cash Flow is derived from our U.S. GAAP-based net cash flow from operating activities plus or minus changes in working capital, amounts determined to be “special items” by our management based on their relative significance to cash flow in a certain period, amounts spent on maintenance capital net of reimbursements and other adjustments not expected to settle in cash;

◦ Pro Forma Distributable Cash Flow is Distributable Cash Flow plus or minus adjustments for the acquisition of noncontrolling interest in connection with that the merger of QEPM with TLLP completed in July 2015;

◦ Distribution Coverage Ratio is calculated as Distributable Cash Flow divided by total distributions; and

◦ Pro Forma Distribution Coverage Ratio is calculated as Pro Forma Distributable Cash Flow divided by total distributions.

Tesoro Logistics LP | 6

We present the performance and liquidity measures defined above because we believe these measures help us analyze our results of operations and liquidity in conjunction with our U.S. GAAP results. Investors, analysts, lenders and ratings agencies may also use these measures to help analyze our results of operations and liquidity in conjunction with our U.S. GAAP results, including but not limited to the following:

• 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.

In addition, these measures are used by management to assess internal performance. We believe these measures, when supplemental to information presented under U.S. GAAP, may provide meaningful information to the users of our financial statements. Each of the performance and liquidity measures should not be used in isolation from their comparable U.S. GAAP measure and thus should not be considered as alternatives to any U.S. GAAP measure. 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.

(f) We exclude maintenance capital expenditures including tank restoration costs and expenditures required to ensure the safety, reliability, integrity and regulatory compliance of our assets with an offset for any reimbursements received for such expenditures.

(g) Prior to 2016 for noncontrolling interests associated with QEPM and Rendezvous Gas Services, L.L.C. (“RGS”), we excluded $2 million of undistributed earnings along with other adjustments to reflect gross cash available for distribution net of noncontrolling interest impacts.

(h) We adjust net cash from operating activities to reflect cash distributions received from equity method investments attributed to the period reported for the purposes of calculating distributable cash flow.

(i) Other includes items that had a non-cash impact on our operations and should not be considered in distributable cash flow. Non-cash items for the nine months ended September 30, 2016 and 2015 include primarily the exclusion of the non-cash gain of $6 million recognized relating the settlement of the Questar Gas Company litigation as discussed in Note 6 to our condensed combined consolidated financial statements and the inclusion of $13 million for acquired deficiency revenue billings to customers in 2015.

(l) Prior to the deconsolidation of RGS as of January 1, 2016, fees paid by us to RGS were eliminated upon consolidation and third-party transactions, including revenue and throughput volumes, were included in our results of operations. Third party volumes associated with RGS, included in gas gathering volume for the three and nine months ended September 30, 2015, were 142 thousand and 145 thousand MMBtu/d, respectively, and reduced our average gas gathering revenue per MMBtu by $0.05 for both periods.

(m) Management uses average revenue per barrel, average revenue per MMBtu and average keep-whole fee per barrel of NGLs to evaluate performance and compare profitability to other companies in the industry. There are a variety of ways to calculate these measures; other companies may calculate these in different ways. We calculate average revenue per barrel as revenue divided by total throughput (barrels). We calculate average revenue per MMBtu as revenue divided by total volume (MMBtu). We calculate average keep-whole fee per barrel as revenue divided by total volume (barrels).
