Non-GAAP Financial Information

This press release contains non-generally accepted accounting principle financial measures that we refer to as adjusted EBITDA, distributable cash flow, gross operating margin, growth capital expenditures, maintenance capital expenditures and the General Partner’s cash available for distribution.  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, 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. We define cash available for distribution for the General Partner as distributions due to the General Partner from the Partnership and the General Partner’s 25% interest in the adjusted EBITDA of EnLink Midstream Holdings, LP (“Midstream Holdings”) less maintenance capital, which is distributed to the General Partner on a monthly basis, less specific general and administrative costs as a separate public reporting entity, the interest costs associated with the General Partner’s debt and current taxes attributable to earnings.

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 and the adjusted EBITDA of Midstream Holdings.  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. Adjusted EBITDA of Midstream Holdings is defined as earnings plus depreciation, provisions for income taxes and distribution of equity investment less income on equity investment.

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.

Gross operating margin, adjusted EBITDA, distributable cash flow, growth capital expenditures, maintenance capital expenditures and cash available for distribution, as defined above, are not measures of financial performance or liquidity under GAAP. They should not be considered in isolation or as an indicator of the Partnership’s and the General Partner’s performance. Furthermore, they should not be seen as a substitute for metrics prepared in accordance with GAAP. Reconciliations of these measures to their most directly comparable GAAP measures are included in the following tables.
