EnLink Midstream Reports Fourth Quarter and Full-Year 2019 Results, Reaffirms 2020 Financial Guidance, and Provides Segment Updates

DALLAS, February 25, 2020 — EnLink Midstream, LLC (NYSE: ENLC) (EnLink) today reported financial results for the fourth quarter and full-year of 2019, reaffirmed previously announced 2020 financial guidance, and provided a segment level update.

Highlights:

CEO Commentary on 2019 and Forward Outlook

“EnLink finished off 2019 with strong adjusted EBITDA performance in the fourth quarter, driven by our diversified asset platform and solid execution. 2019 was a year of transition for EnLink, including the evolution from a period of high growth into an era of operational optimization. We continue to take necessary actions to position EnLink financially and operationally for long-term success, while maintaining an unrelenting commitment to deliver best-in-class services reliably and safely,” said Barry E. Davis, EnLink Chairman and Chief Executive Officer.

"Our large-scale, diversified platform generates significant, stable cash flows from our two growth platforms in the Permian and Louisiana, and our two strong, free-cash-flow-generating systems in Oklahoma and North Texas. The Permian continues to drive near-term growth, with producers remaining very active on our footprint, while our Louisiana platform provides long-term growth opportunities.

"We are confident that the earnings power of our platform combined with our execution plan will deliver superior returns for investors over the long-term. As we turn to 2020 and beyond, we believe our strategic asset platform will allow us to differentiate EnLink by generating excess free cash flow, supported by manageable capital needed to modestly grow adjusted EBITDA."

Adjusted EBITDA, distributable cash flow, and excess free cash flow used in this press release are non-GAAP measures and are explained in greater detail under “Non-GAAP Financial Information and Other Definitions” below.

Non-GAAP Financial Information and Other Definitions

This press release contains non-generally accepted accounting principles financial measures that we refer to as adjusted EBITDA, distributable cash flow available to common unitholders (distributable cash flow), excess free cash flow, and segment free cash flow all as defined below:

We define adjusted EBITDA as net income (loss) plus interest expense, net of interest income; income tax expense (benefit); depreciation and amortization; impairments; loss on secured term loan receivable; distributions from unconsolidated affiliate investments; (gain) loss on disposition of assets; unit-based compensation; transaction costs; (income) loss from unconsolidated affiliate investments; (gain) loss on non-cash derivatives; and accretion expense associated with asset retirement obligations; less non-cash revenue from contract restructuring; gain on extinguishment of debt; payments under onerous performance obligation; non-cash rent; and non-controlling interest.

We define distributable cash flow as adjusted EBITDA (defined above, net to ENLC), less interest expense, loss (gain) on settlement of interest rate swaps, current income taxes and other non-distributable cash flows, accrued cash distributions on EnLink Midstream Partners, LP’s (“ENLK”) Series B Cumulative Convertible Preferred Units (the “ENLK Series B Preferred Units”) and ENLK’s Series C Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units (“ENLK Series C Preferred Units”) paid or expected to be paid, and maintenance capital expenditures, excluding maintenance capital expenditures that were contributed by other entities and relate to the non-controlling interest share of our consolidated entities.

Excess free cash flow is defined as distributable cash flow less distributions declared on common units and growth capital expenditures, which are net to EnLink after giving effect to the contributions by other entities related to the non-controlling interest share of our consolidated entities

Segment Free Cash Flow is defined as segment profit less growth and maintenance capital expenditures, which are gross to EnLink prior to giving effect to the contributions by other entities related to the non-controlling interest share of our consolidated entities.

EnLink believes these measures are useful to investors because they may provide users of this financial information with meaningful comparisons between current results and previously reported results and a meaningful measure of the company’s cash flow after it has satisfied the capital and related requirements of its operations. In addition, adjusted EBITDA achievement is a primary metric used in our short-term incentive program for compensating employees.

Adjusted EBITDA, distributable cash flow, excess free cash flow and segment free cash flow, 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 EnLink’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. See ENLC’s filings with the Securities and Exchange Commission for more information.

Other definitions and explanations of terms used in this press release:

Distribution coverage is calculated by dividing distributable cash flow by distributions declared to common unitholders.

Growth capital expenditures generally include capital expenditures made for acquisitions or capital improvements that we expect will increase our asset base, operating income or operating capacity over the long-term. Maintenance capital expenditures generally include 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.

Segment profit (loss) is defined as operating income (loss) plus general and administrative expenses, depreciation and amortization, (gain) loss on disposition of assets, impairments, and (gain) loss on litigation settlement. Segment profit (loss) includes non-cash compensation expenses reflected in operating expenses. ​
