Summit Midstream Partners, LP Reports First Quarter 2020

Financial and Operating Results

Houston, Texas (May 8, 2020) – Summit Midstream Partners, LP (NYSE: SMLP) announced today its financial and operating results for the three months ended March 31, 2020, including net income of $5.3 million, adjusted EBITDA of $66.1 million and DCF of $34.2 million.  Operated natural gas volume throughput averaged 1,281 MMcf/d and liquids volume throughput averaged 98 Mbbl/d in the quarter.  Natural gas volume throughput benefitted from the on-time commissioning of a five-well pad site behind our Utica Shale gathering system in mid-March 2020.  This pad site is generating aggregate production rates in excess of 160 MMcf/d, which exceeded the expectations set forth in our original financial guidance by more than 15%.  We expect this system will be a growth driver for us over the next several quarters as natural gas forward pricing has strengthened in the second half of 2020 and will incentivize upstream activity in this and other natural gas-focused basins in which we operate.

Heath Deneke, President and Chief Executive Officer, commented, “We are operating in unprecedented times given the prevailing commodity price backdrop and COVID-19 pandemic. As a result of the current environment, many of our customers have updated their forecasts to reflect the steps they are taking to reduce capital budgets, delay and defer drilling and completion activities, and on a limited scale, temporarily curtail existing production.  On May 3, 2020, we released updated 2020 adjusted EBITDA and capital expenditures guidance that was based on revised customer information.  As previously reported, we expect our 2020 adjusted EBITDA to trend towards the low-end of our original $260 million to $285 million guidance range and for our 2020 capital expenditures range to be down by 33% at the midpoint.  We will continue to monitor our customers’ month to month decisions regarding to what extent, if any, curtailments of production will continue beyond May 2020 and we will continue to work aggressively to find ways to further reduce operating expenses and capital expenditures.  I’m proud of how quickly our employees have adapted to the current environment, while maintaining their commitment to operate safely, effectively and focus on initiatives that are within our control.”

“Many of our customers, particularly in our liquids-focused areas such as the Williston and DJ basins, have responded to the current market conditions by reducing rig activity and deferring well completions.  Our customers currently have nearly 60 DUCs behind our liquids-oriented assets, which represent an identifiable catalyst once crude oil prices improve. Natural gas prices have strengthened in recent weeks and while that is encouraging over the longer term, at this time, we do not expect near term volumes in our natural gas-focused areas to change materially relative to our original financial guidance for 2020.  Challenging markets like the one we are currently in highlight the strength of Summit’s diversified business model.  For the first quarter of 2020, approximately 69% of our segment adjusted

EX 99.1-1

EBITDA originated from our natural gas-focused segments, which provide relative stability for SMLP while preserving significant upside relative to future improvements to crude oil and liquids prices.”

“In an effort to continue to reposition the business and transform our governance structure to be fully aligned with SMLP unitholders, on May 3, 2020, we entered into a definitive agreement with Energy Capital Partners II, LLC (“ECP”) to acquire Summit Midstream Partners, LLC, the private entity that owns SMP Holdings, as well as 5.9 million common units owned directly by ECP, for $35 million in cash plus warrants covering 10 million SMLP common units.  As a result of this acquisition, SMP Holdings will become an indirect, unrestricted subsidiary of SMLP, which will give us ownership of SMLP’s general partner, the $180.75 million DPPO receivable, and 45.3 million SMLP units.  SMP Holdings will remain liable for a $158.2 million term loan which is due in May 2022 and is secured by 34.6 million SMLP common units and the GP interest.  As an unrestricted subsidiary, SMP Holdings’ term loan will continue to be non-recourse indebtedness to SMLP and its operating subsidiaries.”

“This simplification transaction is transformational for SMLP and upon closing, the Board will consist of a majority of independent directors.  Concurrent with the closing of the transaction, we will also amend our partnership agreement to provide for the public election of directors beginning in 2022, which further aligns the interests of the Board and our public unitholders.  We are very excited about this transaction and believe it is in the best long-term interest of all of SMLP’s stakeholders.”

“Liquidity and balance sheet strength is paramount for SMLP, particularly during this volatile time in the crude oil and natural gas market, and we believe the GP Buy-in Transaction prioritizes this focus.  Concurrent with the GP Buy-in Transaction, we announced the suspension of approximately $76 million of annualized common and preferred distributions which otherwise would have been distributed out of the business.  In connection with the GP Buy-in Transaction, the $35 million of acquisition proceeds will be loaned back from ECP to Summit Midstream Holdings, LLC, thereby enhancing our liquidity and financial flexibility.  As a result of the decision to suspend our common and

EX 99.1-2

preferred distributions, SMLP expects to generate sufficient cash in 2020, after capital expenditures, to reduce outstanding indebtedness by more than $100 million.”

“We also continue to actively evaluate potential asset divestitures and joint ventures of certain of our Legacy and Core Focus Areas and will continue to do so in a patient and disciplined manner.  Our expectation is that any divestiture will serve to further accelerate de-leveraging of SMLP’s balance sheet.”

2020 Financial Guidance

SMLP is reaffirming the updated 2020 financial guidance that it provided on May 3, 2020.  Projections associated with this guidance are subject to risks and uncertainties as described in the “Forward-Looking Statements” section at the end of this release.

The financial guidance incorporates a slow-down in activity and a deferral of well completions from customers predominantly in the Williston Basin and DJ Basin reportable segments.  The guidance also incorporates instances of temporary economic shut-ins of existing production as a result of the low commodity price environment and prevailing storage constraints in certain crude oil and condensate production basins, including the Williston Basin, DJ Basin and the condensate window of the Utica Shale.  Although many producers in the Permian Basin have announced plans to reduce activity, we currently expect volume throughput and the activity from our customers to be in-line with the forecast used to produce our initial guidance range.  SMLP’s 2020 financial guidance remains largely unchanged relative to its initial guidance for its natural gas-focused reportable segments.

Our 2020 growth capital expenditures plan is relatively flexible and can adapt to changing market conditions given that most projects are aligned with the schedules of our customers and in many cases can be canceled or deferred.  As such, we reduced our planned investments for 2020, which are comprised of primarily growth capital reductions, by 33% relative to our original financial guidance at the midpoint.  Below is a summary of the updates that were released on May 3, 2020 to our 2020 financial guidance:

Updates to Financial Guidance (Released on May 3, 2020)

First Quarter 2020 Business Highlights

In the first quarter of 2020, SMLP’s average daily natural gas throughput for its operated systems decreased 5.5% relative to the fourth quarter of 2019, to 1,281 MMcf/d, and liquids volumes decreased 17.3% relative to the fourth quarter of 2019, to 98 Mbbl/d.  SMLP’s customers currently have approximately 89 DUCs in inventory upstream of our systems.

EX 99.1-6

Capital Expenditures

Capital expenditures totaled $18.6 million in the first quarter of 2020, including maintenance capital expenditures of $5.1 million, a decrease of 39.3% compared to the fourth quarter of 2019.  Capital expenditures in the first quarter of 2020 were primarily related to growth projects in our Williston Basin, DJ Basin and Permian Basin segments, as well as expenditures associated with the relocation of our corporate headquarters.   

__________

Capital & Liquidity

As of March 31, 2020, SMLP had $542.9 million of undrawn commitments under its $1.25 billion revolving credit facility.  Subject to covenant limits, and after accounting for a $9.1 million issued but undrawn letter of credit, our available borrowing capacity at March 31, 2020 was approximately $120 million.

Based upon the terms of SMLP’s revolving credit facility and total outstanding debt, net of cash, of $1.43 billion (inclusive of $800.0 million of senior unsecured notes), SMLP’s total leverage ratio and senior secured leverage ratio (as defined in the credit agreement) as of March 31, 2020, were 5.05 to 1.0 and 2.26 to 1.0, respectively, relative to maximum threshold limits of 5.50 to 1.0 and 3.75 to 1.0.

Double E Update

During the first quarter of 2020, SMLP made cash investments totaling $58.0 million with respect to its 70% equity investment in Double E Pipeline, LLC and as of March 31, 2020, $65 million of the $80 million Subsidiary Series A Preferred Units had been issued.  SMLP is actively pursuing a non-recourse commercial bank financing to fund the substantial majority of SMLP’s remaining Double E capital obligations, which would defer to 2021 any additional SMLP investment beyond the approximately $10 million expected in 2020.  The Double E project is proceeding in-line with our expected timeline.   In March, we received an environmental assessment report from the Federal Energy Regulatory Commission (“FERC”) and we continue to expect to receive a FERC 7(c) certificate for Double E in the third quarter of 2020.

MVC Shortfall Payments

SMLP billed its customers $12.9 million in the first quarter of 2020 related to MVC shortfalls.  For those customers that do not have MVC shortfall credit banking mechanisms in their gathering agreements, the MVC shortfall payments are accounted for as gathering revenue in the period in which they are earned.  In the first quarter of 2020, SMLP recognized $20.6 million of gathering revenue associated with MVC shortfall payments.  SMLP also recognized $5.4 million of negative adjustments to MVC shortfall payments in the first quarter of 2020 related to shortfall payment adjustments from customers in the Williston Basin segment and the Piceance Basin segment.  SMLP’s MVC shortfall payment mechanisms contributed $15.1 million of total adjusted EBITDA in the first quarter of 2020.

Quarterly Distribution Update

On May 3, 2020, the board of directors of SMLP’s general partner suspended the distribution payable on its common units and on its 9.50% Series A fixed-to-floating rate cumulative redeemable perpetual preferred units.  The suspension of the common and preferred distributions will enable SMLP to retain an incremental approximately $76 million of cash in the business annually, which it intends to use to de-lever the balance sheet, enhance liquidity and increase financial flexibility.  The unpaid distributions on the preferred units will continue to accrue.

First Quarter 2020 Earnings Call Information

SMLP will host a conference call at 10:00 a.m. Eastern on Friday, May 8, 2020, to discuss its quarterly operating and financial results.  Interested parties may participate in the call by dialing 847-585-4405 or toll-free 888-771-4371 and entering the passcode 49631232.  The conference call, webcast live and archive of the call can be accessed through the Investors section of SMLP's website at www.summitmidstream.com.

Use of Non-GAAP Financial Measures

We report financial results in accordance with U.S. generally accepted accounting principles (“GAAP”).  We also present adjusted EBITDA and distributable cash flow, each a non-GAAP financial measure.  We define adjusted EBITDA as net income or loss, plus interest expense, income tax expense, depreciation and amortization, our proportional adjusted EBITDA for equity method investees, adjustments related to MVC shortfall payments, adjustments related to capital reimbursement activity, unit-based and noncash compensation, the change in the Deferred Purchase Price Obligation present value, impairments, items of income or loss that we characterize as unrepresentative of our ongoing operations and other noncash expenses or losses, less interest income, income tax benefit, income (loss) from equity method investees and other noncash income or gains.  We define distributable cash flow as adjusted EBITDA plus cash interest received and cash taxes received, less cash interest paid, senior notes interest adjustment, distributions to Series A Preferred unitholders, Series A Preferred units distribution adjustment, cash taxes paid and maintenance capital expenditures.  Because adjusted EBITDA and distributable cash flow may be defined differently by other entities in our industry, our definitions of these non-GAAP financial measures may not be comparable to similarly titled measures of other entities, thereby diminishing their utility.

Management uses these non-GAAP financial measures in making financial, operating and planning decisions and in evaluating our financial performance. Furthermore, management believes that these non-GAAP financial measures may provide external users of our financial statements, such as investors, commercial banks, research analysts and others, with additional meaningful comparisons between current results and results of prior periods as they are expected to be reflective of our core ongoing business.

Adjusted EBITDA and distributable cash flow are used as supplemental financial measures by external users of our financial statements such as investors, commercial banks, research analysts and others.

EX 99.1-8

Adjusted EBITDA is used to assess:

Distributable cash flow is used to assess:

Both of these measures have limitations as analytical tools and investors should not consider them in isolation or as a substitute for analysis of our results as reported under GAAP.  For example:

We compensate for the limitations of adjusted EBITDA and distributable cash flow as analytical tools by reviewing the comparable GAAP financial measures, understanding the differences between the financial measures and incorporating these data points into our decision-making process.  Reconciliations of GAAP to non-GAAP financial measures are attached to this press release.

We do not provide the GAAP financial measures of net income or loss or net cash provided by operating activities on a forward-looking basis because we are unable to predict, without unreasonable effort, certain components thereof including, but not limited to, (i) income or loss from equity method investees and (ii) asset impairments.  These items are inherently uncertain and depend on various factors, many of which are beyond our control.  As such, any associated estimate and its impact on our GAAP performance and cash flow measures could vary materially based on a variety of acceptable management assumptions.
