Forward-Looking Statements This presentation contains forward-looking statements within the meaning of the federal securities laws. Although these statements reflect the current views, assumptions and expectations of our management, the matters addressed herein involve certain risks and uncertainties that could cause actual activities, performance, outcomes and results to differ materially than those indicated. Such forward-looking statements include, but are not limited to, statements about future financial and operating results, guidance, projected or forecasted financial results, objectives, project timing, expectations and intentions and other statements that are not historical facts. Factors that could result in such differences or otherwise materially affect our financial condition, results of operations and cash flows include, without limitation, (a) the dependence on Devon for a substantial portion of the natural gas that we gather, process and transport, (b) our lack of asset diversification, (c) our vulnerability to having a significant portion of our operations concentrated in the Barnett Shale, (d) the amount of hydrocarbons transported in our gathering and transmission lines and the level of our processing and fractionation operations, (e) fluctuations in oil, natural gas and NGL prices, (f) construction risks in our major development projects, (g) our ability to consummate future acquisitions, successfully integrate any acquired businesses, realize any cost savings and other synergies from any acquisition, (h) changes in the availability and cost of capital, (i) competitive conditions in our industry and their impact on our ability to connect hydrocarbon supplies to our assets, (j) operating hazards, natural disasters, weather-related delays, casualty losses and other matters beyond our control, (k) a failure in our computing systems or a cyber-attack on our systems, and (l) the effects of existing and future laws and governmental regulations, including environmental and climate change requirements and other uncertainties. These and other applicable uncertainties, factors and risks are described more fully in EnLink Midstream Partners, LP s and EnLink Midstream, LLC s filings with the Securities and Exchange Commission, including EnLink Midstream Partners, LP s and EnLink Midstream, LLC s Annual Reports on Form 10-K, Quarterly Reports on Form 10- Q and Current Reports on Form 8-K. Neither EnLink Midstream Partners, LP nor EnLink Midstream, LLC assumes any obligation to update these forward-looking statements. The assumptions and estimates underlying the forecasted financial information included in the guidance information in this press release are inherently uncertain and, though considered reasonable by the EnLink Midstream management team as of the date of its preparation, are subject to a wide variety of significant business, economic, and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the forecasted financial information. Accordingly, there can be no assurance that the forecasted results are indicative of EnLink Midstream s future performance or that actual results will not differ materially from those presented in the forecasted financial information. Inclusion of the forecasted financial information in this press release should not be regarded as a representation by any person that the results contained in the forecasted financial information will be achieved. 2

Non-GAAP Financial Information This presentation contains non-generally accepted accounting principle financial measures that we refer to as adjusted EBITDA, distributable cash flow, gross operating margin, growth capital expenditures, adjusted EBITDA of EnLink Midstream Holdings (EMH) and maintenance capital expenditures. We define adjusted EBITDA as net income from continuing operations plus interest expense, provision for income taxes, depreciation and amortization expense, impairment expense, stock-based compensation, gain on noncash derivatives, transaction costs, distribution of equity investment and non-controlling interest and income on equity investment. We define distributable cash flow as net cash provided by operating activities plus adjusted EBITDA, net to EnLink Midstream Partners, LP less interest expense, litigation settlement adjustment, interest rate swap, cash taxes and other, maintenance capital expenditures and Predecessor adjusted EBITDA. Gross operating margin is defined as revenue minus the cost of purchased gas, NGL, condensate and crude oil. Growth capital expenditures are defined as all construction-related direct labor and material costs, as well as indirect construction costs including general engineering costs and the costs of funds used in construction. Adjusted EBITDA of EMH is defined as earnings plus depreciation, provisions for income taxes and distribution of equity investment less income on equity investment. The amounts included in the calculation of these measures are computed in accordance with generally accepted accounting principles (GAAP) with the exception of maintenance capital expenditures. Maintenance capital expenditures are capital expenditures made to replace partially or fully depreciated assets in order to maintain the existing operating capacity of the assets and to extend their useful lives. The Partnership and General Partner believe these measures are useful to investors because they may provide users of this financial information with meaningful comparisons between current results and prior-reported results and a meaningful measure of the Partnership s and the General Partner's cash flow after it has satisfied the capital and related requirements of its operations. 3
