2 Forward Looking Statements and Non-GAAP Measures This presentation contains certain forward-looking statements within the meaning of the federal securities law. Words such as anticipates, believes, expects, intends, will, should, may, estimate and similar expressions may be used to identify forward-looking statements. Forward-looking statements are not statements of historical fact and reflect Noble Midstream Partners LP s ( the Partnership or Noble Midstream ) current views about future events. No assurances can be given that the forward-looking statements contained in this presentation will occur as projected, and actual results may differ materially from those projected. Forward-looking statements are based on current expectations, estimates and assumptions that involve a number of risks and uncertainties that could cause actual results to differ materially from those projected. These risks include, without limitation, Noble Energy Inc. s ability to meet their drilling and development plans, changes in general economic conditions, competitive conditions in the Partnership s industry, actions taken by third-party operators, gatherers, processors and transporters, the demand for crude oil and natural gas gathering and processing services, the Partnership s ability to successfully implement its business plan, the Partnership s ability to complete internal growth projects on time and on budget, the price and availability of debt and equity financing, the availability and price of crude oil and natural gas to the consumer compared to the price of alternative and competing fuels, and other risks inherent in the Partnership s business that are discussed in its most recent registration statement on Form S-1 and in the Partnership s other reports on file with the Securities and Exchange Commission ( SEC ). These reports are also available from the Partnership s office or website, www.nblmidstream.com. Forward-looking statements are based on the estimates and opinions of management at the time the statements are made. Noble Midstream does not assume any obligation to update forward-looking statements should circumstances or management's estimates or opinions change. This presentation also contains certain non-gaap measures of financial performance that management believes are good tools for internal use and the investment community in evaluating Noble Midstream s overall financial performance. Please see the attached schedules for reconciliations of the non-gaap financial measures used in this presentation to the most directly comparable GAAP financial measures. In this presentation, we refer to certain results as attributable to the Partnership. Unless otherwise noted herein, this reflects the results of the Partnership as if it had been in existence for the entire second and third quarters of 2016 and excludes the non-controlling s in the development companies ( DevCos ) retained by Noble Energy in connection with the closing of our IPO on September 20, 2016. We believe the results attributable to the Partnership provide the best representation of the ongoing operations from which our unitholders will benefit. Unless otherwise noted herein, all other results included in this presentation reflect the results of our predecessor for accounting purposes (our Predecessor ), for periods prior to the closing of the IPO, as well as the results of our Partnership, for the 10 day period subsequent to the closing of the IPO.

19 EBITDA Reconciliation Non-GAAP Financial Measures This presentation includes EBITDA and Distributable Cash Flow, both of which are non- GAAP measures which may be used periodically by management when discussing our financial results with investors and analysts. The following presents a reconciliation of each of these non-gaap financial measures to their nearest comparable GAAP measure. $ in millions 4Q '16 Current Est. 3Q '16 Actual We define EBITDA as net income before income taxes, net expense, depreciation and amortization. EBITDA is used as a supplemental financial measure by management and by external users of our financial statements, such as investors, industry analysts, lenders and ratings agencies, to assess: our operating performance as compared to those of other companies in the midstream energy industry, without regard to financing methods, historical cost basis or capital structure; the ability of our assets to generate sufficient cash flow to make distributions to our partners; 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. We define Distributable Cash Flow as EBITDA less estimated maintenance capital expenditures. Distributable Cash Flow is used by management to evaluate our overall performance. Our partnership agreement requires us to distribute all available cash on a quarterly basis, and Distributable Cash Flow is one of the factors used by the board of directors of our general partner (the Board ) to help determine the amount of available cash that is available to our unitholders for a given period. We believe that the presentation of EBITDA and Distributable Cash Flow provide information useful to investors in assessing our financial condition and results of operations. The GAAP measure most directly comparable to EBITDA and Distributable Cash Flow is net income. EBITDA and Distributable Cash Flow should not be considered alternatives to net income, net cash provided by (used in) operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP. Net Income $34 - $37 $22.4 Add: Depreciation and Amortization 2 3 2.3 Add: Interest Expense, Net of Amount Capitalized 0 2.5 Add: Income Tax Provision 0 11.1 EBITDA $36 - $40 $38.2 Less: EBITDA Attributable to Noncontrolling Interests 10 11 8.6 EBITDA Attributable to NBLX $26 - $29 $29.6 Less: Maintenance Capital Expenditures 2 1.9 Distributable Cash Flow of NBLX $24 - $27 $27.7 EBITDA and Distributable Cash Flow exclude some, but not all, items that affect net income, and these measures may vary from those of other companies. As a result, EBITDA and Distributable Cash Flow as presented herein may not be comparable to similarly titled measures of other companies. EBITDA and Distributable Cash Flow should not be considered as alternatives to GAAP measures, such as net income, operating income, cash flow from operating activities, or any other GAAP measure of financial performance.

Crude oil treating fee is not acreage based. NBLX receives monthly fee for each Noble operated well producing in paying quantities in Weld County not connected to NBLX crude oil gathering systems during each month, which was 4,480 wells as of June 30, 2016. 2. NBLX currently has limited midstream infrastructure assets in the Mustang IDP and no midstream infrastructure assets in the Bronco IDP. The assets in these IDP areas currently consist primarily of dedications to us from Noble for future production in these IDP areas. In the Mustang IDP, NBLX also owns one fresh water storage pond and certain rights-of-way and surface rights. NBLX anticipates the first centralized facility servicing the Mustang IDP and related gathering infrastructure to be in service by the end of 2017. 3. NBLX assets in Greeley Crescent IDP currently consist of dedications from Noble and an unaffiliated third party. On May 3, 2016, Noble announced a sale of approximately 33,000 net acres to such third party. All acreage in the Greeley Crescent IDP remains subject to the dedication in favor of NBLX for crude oil gathering, produced water services and fresh water services. 4. On June 15, 2016, Noble entered into an acreage swap pursuant to which Noble will increase its holdings in the Wells Ranch IDP by approximately 11,700 net acres in exchange for reducing its in the Bronco IDP by approximately 13,500 net acres. Upon completion, all of the outbound acreage in the Bronco IDP will be released from the prior dedications to NBLX, and the inbound acreage in the Wells Ranch IDP will become dedicated to NBLX. After giving effect to this acreage swap, the dedication in the Wells Ranch IDP is approximately 79,000 net acres and the dedication in the Bronco IDP is approximately 36,000 net acres. 5. Includes acreage currently dedicated to other providers for produced water services and committed to NBLX upon expiration of existing dedications. The majority of these dedications will expire or are expected to be terminated by Noble by the time NBLX s planned infrastructure is operational in 2017. 6. NBLX currently provides produced water services through third party transportation providers and saltwater disposal facilities, and may provide additional produced water services in the future.
