NYSE: TLLP Wells Fargo Securities Pipeline, MLP, and Energy Symposium December 2013 Tesoro Logistics LP Exhibit 99.1

2 This Presentation includes forward-looking statements. These statements relate to, among other things, the following: execution of our strategy, including growth and expansion projects and the resulting volumetric improvements, asset optimization opportunities, and growth in third party business and revenues; cash flows; the timing and amount of capital expenditures; our leverage targets and anticipated cost of capital; the proportion of Tesoro’s total consolidated EBITDA represented by our operations; and other aspects of future performance. We have used the words “anticipate,” “believe,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “predict,” “project,” “should,” “will,“ “potential” and similar terms and phrases to identify forward-looking statements in this Presentation. Although we believe the assumptions upon which these forward-looking statements are based are reasonable, any of these assumptions could prove to be inaccurate and the forward-looking statements based on these assumptions could be incorrect. Our operations involve risks and uncertainties, many of which are outside of our control, and any one of which, or a combination of which, could materially affect our results of operations and whether the forward-looking statements ultimately prove to be correct. Actual results and trends in the future may differ materially from those suggested or implied by the forward-looking statements depending on a variety of factors which are described in greater detail in our filings with the SEC. Please see our Risk Factor disclosures included in our 2012 Annual Report on Form 10-K and our quarterly reports on Form 10-Q. All future written and oral forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the previous statements. We undertake no obligation to update any information contained herein or to publicly release the results of any revisions to any forward- looking statements that may be made to reflect events or circumstances that occur, or that we become aware of, after the date of this Presentation. We have included annual EBITDA and distributable cash flow, each of which is a non-GAAP financial measure, for the company. Please see the Appendix for the definition and reconciliation of these amounts. Forward Looking Statements

Appendix

19 Non-GAAP Financial Measures (a) We believe that this presentation of our results of operations excluding results of our "Predecessors" will provide useful information to investors in assessing our financial condition and results of operations. We believe investors want to analyze operations of our business under our current commercial agreements with Tesoro. This non-GAAP financial metric should not be considered in isolation or as a substitute for analysis of our results as reported under U.S. GAAP. (b) We define earnings before interest, income taxes, depreciation and amortization expenses (“EBITDA”) as net income before depreciation and amortization expenses, net interest and financing costs and interest income. We define adjusted EBITDA as EBITDA plus costs incurred for the inspection and maintenance program associated with the Northwest Products System. We define distributable cash flow as adjusted EBITDA less maintenance capital expenditures and net interest and financing costs, plus reimbursement by Tesoro for certain maintenance capital expenditures and other reimbursements by Tesoro, non-cash unit-based compensation expense, loss on asset disposals, the change in deferred revenue, and interest income. EBITDA, adjusted EBITDA and distributable cash flow are not measures prescribed by U.S. GAAP (“non-GAAP”) but are supplemental financial measures that are used by management and may be used by external users of our financial statements, such as industry analysts, investors, lenders and rating agencies, to assess: • our operating performance as compared to other publicly traded partnerships in the midstream energy industry, without regard to 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.
