EnLink Midstream Reports Second Quarter 2021, Expects 2021
Adjusted EBITDA in the Upper End of June Guidance

DALLAS, August 3, 2021 — EnLink Midstream, LLC (NYSE: ENLC) (EnLink) reported financial results for the second quarter of 2021.

Highlights

"EnLink delivered another solid quarter of operating and financial results as we continue to make progress on our strategic plan," said Barry E. Davis, EnLink Chairman and CEO. "With the tremendous execution by our team, continued momentum in producer activity on our footprint, and strong commodity prices, we expect to end 2021 in the upper end of our previously updated adjusted EBITDA guidance range of $1.02 to $1.06 billion, which was itself a 7% increase over our original full-year 2021 guidance at the midpoint.

"Our vision is to become the future of midstream by leading in innovation and creating sustainable value for EnLink and our unitholders. We took big steps toward achieving this vision with the creation of our Carbon Solutions Group, which will work on decarbonization projects that create compelling business opportunities for EnLink and our industrial partners, while also strengthening EnLink's leading role in the global energy transition. Our extensive network of pipelines in Louisiana and decades of operational excellence uniquely positions us to build a carbon capture and sequestration business that is mutually beneficial to EnLink and our existing customer base along the Mississippi River corridor, one of the highest CO₂-emitting regions in the country."

Adjusted EBITDA, segment cash flow, and free cash flow after distributions used in this press release are non-GAAP measures and are explained in greater detail under "Non-GAAP Financial Information" below.

Non-GAAP Financial Information

This press release contains non-generally accepted accounting principles financial measures that we refer to as adjusted EBITDA, free cash flow after distributions, and segment cash flow.

We define adjusted EBITDA as net income (loss) plus (less) interest expense, net of interest income; depreciation and amortization; impairments; (income) loss from unconsolidated affiliate investments; distributions from unconsolidated affiliate investments; (gain) loss on disposition of assets; (gain) loss on extinguishment of debt; unit-based compensation; income tax expense (benefit); unrealized (gain) loss on commodity swaps; relocation costs associated with the War Horse processing facility; accretion expense associated with asset retirement obligations; transaction costs; (non-cash rent); and (non-controlling interest share of adjusted EBITDA from joint ventures).

We define free cash flow after distributions as adjusted EBITDA, net to ENLC, plus (less) (growth capital expenditures, excluding capital expenditures that were contributed by other entities and relate to the non-controlling interest share of our consolidated entities); (maintenance capital expenditures, excluding capital expenditures that were contributed by other entities and relate to the non-controlling interest share of our consolidated entities); (interest expense, net of interest income); (distributions declared on common units); (accrued cash distributions on Series B Preferred Units and Series C Preferred Units paid or expected to be paid); (relocation costs associated with the War Horse processing facility); (payments to terminate interest rate swaps); non-cash interest (income)/expense; (current income taxes); and proceeds from the sale of equipment and land.

We define segment cash flow 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 and free cash flow after distributions are both used as metrics in our short-term incentive program for compensating employees.

Adjusted EBITDA, free cash flow after distributions, and segment 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.

Forward-Looking Reconciliation of Net Income to Adjusted EBITDA and Free Cash Flow After Distributions

(All amounts in millions)

(Unaudited)

EnLink Midstream does not provide a reconciliation of forward-looking Net Cash Provided by Operating Activities to Adjusted EBITDA and Excess Free Cash Flow because the companies are unable to predict with reasonable certainty changes in working capital, which may impact cash provided or used during the year. Working capital includes accounts receivable, accounts payable and other current assets and liabilities. These items are uncertain and depend on various factors outside the companies' control. For the same reasons, EnLink is unable to address the probable significance of the unavailable information, which could be material to future results.
