EnLink Midstream Reports First Quarter 2021 Results and Reaffirms 2021 Guidance

DALLAS, May 4, 2021 — EnLink Midstream, LLC (NYSE: ENLC) (EnLink) reported financial results for the first quarter of 2021 and reaffirmed 2021 financial guidance.

Highlights

"We are pleased with the results that EnLink achieved in the first quarter, made possible by the relentless hard work of the EnLink team working around the clock to minimize the impact from Winter Storm Uri," said Barry E. Davis, EnLink Chairman and CEO. "We are thankful for our employees who continue to execute our strategic plan, and, because of their hard work, all of our business segments generated strong cash flow, putting us on a path to achieve our previously announced guidance.

"After a 2020 that showed the resiliency of our business, we are continuing to focus on generating strong free cash flow, prudently managing our balance sheet, and growing the business. We see 2021 and beyond as an opportunity to transform how we operate and to get better, more efficient, and more sustainable. I look forward to sharing how EnLink is becoming the future of midstream through the execution of our strategic plan."

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.

First Quarter 2021 Financial Results and Highlights

*As calculated under EnLink's Revolver.

**Outstanding common units as of April 29, 2021, February 11, 2021, and April 30, 2020, respectively.

Winter Storm Uri Impact

Winter Storm Uri had a similar impact on EnLink as that experienced across the midstream industry with a temporary, but significant, decrease to the volumes across EnLink's geographically diverse asset footprint. The severe cold temperatures caused production freeze-offs and led some producers to proactively shut in their wells. This reduced production flow lasted approximately 10 days, during which EnLink saw peak volume declines range between 44% and 92%, depending on the region. However, thanks to the extraordinary efforts of our employees, EnLink did not experience any asset integrity issues or safety incidents during this period, and system volumes have returned to pre-Uri levels.

The extreme weather created a number of challenges that adversely impacted the first quarter. As a result of the temporary reduction in gathered and processed volumes, EnLink suffered marketing-related losses, including losses on derivative contracts and losses related to firm commodity sales agreements.

EnLink's employees worked diligently during the extreme weather to minimize the negative impacts on our business, to ensure customer needs were met to the extent possible, and to reduce the duration of the operational disruption.

In spite of these challenges, EnLink's resilient assets and focus on operational excellence helped to create offsetting operational savings. EnLink was able to make limited incremental gas sales to support local markets in less operationally affected regions and to use its storage capacity in Louisiana, including at the new Jefferson Island Storage Hub (JISH) facility, to help offset lower gas and NGL supply. Additionally, because of forced outages at facilities and elevated power prices, EnLink received approximately $40 million in credits for unused electricity which had been purchased on a firm basis. These credits may be used to offset future electricity costs. On a net basis, it is estimated Winter Storm Uri did not have a material impact to the first quarter of 2021 results.

The effects of Winter Storm Uri on our industry are far ranging and industrywide litigation and billing disputes arising out of the storm will take time to resolve. As a result, EnLink may be subject to additional financial impact in future quarters.

Amarillo Rattler Acquisition

On April 30, 2021, EnLink purchased Amarillo Rattler, the owner of a gathering and processing system located in the Midland Basin, which represents a great example of EnLink's opportunistic tuck-in acquisition strategy. In connection with the purchase, EnLink entered into an amended and restated gas gathering and processing agreement with Diamondback Energy, strengthening EnLink's dedicated acreage position and deepening its relationship with Diamondback Energy. EnLink acquired the system for $60 million (including $10 million to be paid in 2022) and an earnout capped at $15 million based on Diamondback Energy drilling activity above historical levels. At 6x 2022E EBITDA, the purchase price represents attractive economics relative to historical multiples in the Permian, partially driven by significant operating synergies, and improving over time as Diamondback Energy develops the acreage. In addition, the acquisition is anticipated to be modestly accretive to FCFAD in FY21.

Emissions Targets and Third Sustainability Report

EnLink will announce via a separate press release today its intention to reach net zero greenhouse gas emissions by 2050, positioning the company among industry leaders in sustainability. EnLink plans to execute substantial emissions reduction strategies along the way that will systematically move the company toward its net zero goal, including achieving a 30% reduction in methane emissions intensity by 2024 and a path to reach a 30% reduction in total carbon dioxide equivalent emissions intensity levels by 2030, both as compared to 2020 levels. The company's environmental commitment is further evidenced by its joining, in March 2021, of The Environmental Partnership, an industry organization focused on emissions reduction solutions. EnLink's emissions commitments and environmental management strategies are detailed in its third annual sustainability report, issued today at http://sustainability.enlink.com. Additionally, the report highlights 2020 governance and social responsibility achievements.

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 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; (gain) loss on disposition of assets; accretion expense associated with asset retirement obligations; (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.

Segment 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 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.

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

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 loss on secured term loan receivable. Segment profit (loss) includes non-cash compensation expenses reflected in operating expenses. See “Item 8. Financial Statements and Supplementary Data - Note 15 - Segment Information” in ENLC’s Annual Report on Form 10-K for the year ended December 31, 2020, and, when available, “Item 1. Financial Statements - Note 13—Segment Information” in ENLC’s Quarterly Report on Form 10-Q for the three months ended March 31, 2021, for further information about segment profit (loss).

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.
