        processing project in the Delaware Basin for XTO Energy

Summit Midstream Partners, LP (NYSE: SMLP) announced today its financial and operating results for the three and six months ended June 30, 2017. SMLP reported net income of $11.2 million for the second quarter of 2017 compared to a net loss of $50.6 million for the prior-year period. Net cash provided by operations totaled $58.9 million in the second quarter of 2017 compared to $64.7 million in the prior-year period. Adjusted EBITDA totaled $72.6 million and distributable cash flow totaled $50.0 million for the second quarter of 2017 compared to $72.4 million and $51.0 million, respectively, for the prior-year period.

Natural gas volume throughput averaged 1,780 million cubic feet per day ("MMcf/d") in the second quarter of 2017, an increase of 17.7% compared to 1,512 MMcf/d in the prior-year period, and an increase of 9.4% compared to 1,627 MMcf/d in the first quarter of 2017. Crude oil and produced water volume throughput in the second quarter of 2017 averaged 68.9 thousand barrels per day ("Mbbl/d"), a decrease of 19.9% compared to 86.0 Mbbl/d in the prior-year period, and a decrease of 9.8% compared to 76.4 Mbbl/d in the first quarter of 2017. SMLP's natural gas volume throughput metrics exclude its proportionate share of volume throughput from its 40% ownership interest in Ohio Gathering.

Steve Newby, President and Chief Executive Officer, commented, "SMLP's financial and operating results for the second quarter of 2017 were in line with our expectations, and we continue to expect volume and cash flow growth in the second half of 2017. Based on recent feedback from certain customers, we expect well completion activity, particularly in the Williston, Piceance and Utica segments, to be slower than originally expected. In many cases, well completion activity will be pushed to later dates in the second half of 2017 and in some cases, from the second half of 2017 into the first half of 2018. As a result, we have lowered the midpoint of our 2017 adjusted EBITDA financial guidance by 4.1% from $305.0 million to $292.5 million.

SMLP had a number of positive developments in the second quarter of 2017 that we expect will benefit our business over the long term. We announced a new gathering and processing project for XTO Energy in the Delaware Basin which is expected to commence operations in the second quarter of 2018. Our largest customer, Encana, sold its Piceance acreage to a private equity-backed E&P company that we expect will be significantly more active behind our Piceance gathering system going forward. We commissioned the TPL-7 connector project behind our Summit Midstream Utica system which helped drive sequential quarterly volume growth on that system from 275 MMcf/d in the first quarter of 2017 to 413 MMcf/d in the second quarter of 2017. We amended our $1.25 billion revolving credit facility and extended the term of the facility from November 2018 to May 2022. Our customers continued their pace of drilling behind our systems with 11 to 12 rigs working throughout the second quarter.

We expect volume and cash flow growth from our existing asset base for the balance of 2017. We are encouraged by our team's commercial efforts, including our recently announced Delaware Basin organic development project, which is expected to be operational in the first half of 2018 at a total investment cost of $110.0 million. We are also currently evaluating a number of new commercial opportunities in and around our existing service area and we expect that these opportunities will lead to incremental growth beginning in 2018."

SMLP reported net income of $10.7 million for the first six months of 2017 compared to a net loss of $54.2 million for the prior-year period. Net cash provided by operations totaled $121.3 million for the first six months of 2017 compared to $131.5 million in the prior-year period. SMLP reported adjusted EBITDA of $144.0 million and distributable cash flow of $103.0 million compared to $142.4 million and $102.5 million, respectively for the prior-year period. Natural gas volume throughput averaged 1,704 MMcf/d for the first six months of 2017 compared to 1,518 MMcf/d in the prior-year period. Crude oil and produced water volume throughput averaged 72.6 Mbbl/d in the first six months of 2017 compared to 90.5 Mbbl/d in the prior-year period.

2017 Financial Guidance

On July 27, 2017, SMLP revised its 2017 financial guidance due to our expectation for a slower pace of well completions in the second half of 2017. The original 2017 adjusted EBITDA guidance range of $295.0 million to $315.0 million was revised to a new range of $285.0 million to $300.0 million. At the midpoint, 2017 adjusted EBITDA was reduced by 4.1% from $305.0 million to $292.5 million.

As a result of our recently announced organic development project in the Delaware Basin, partially offset by slower capital spending across our other basins, SMLP also updated its 2017 capital expenditure guidance to a new range of $125.0 million to $150.0 million, including maintenance capex of $15.0 million to $20.0 million. SMLP's 2017 capex guidance reflects the inclusion of our contributions to equity method investees. SMLP expects its full year distribution coverage will range from 1.10x to 1.20x.

                     one-month lag.

Utica Shale

The Utica Shale reportable segment includes Summit Midstream Utica ("SMU"), the natural gas gathering system operated by SMLP which is currently in service and under development in Belmont and Monroe counties in southeastern Ohio. Summit Utica gathers and delivers dry natural gas to interconnections with a third-party intrastate pipeline that provides access to the Clarington Hub.

Segment adjusted EBITDA for the second quarter of 2017 totaled $9.5 million, up 102% from $4.7 million for the prior-year period, primarily due to higher volume throughput across the SMU system. Volume throughput at SMU averaged 413 MMcf/d in the second quarter of 2017 compared to 167 MMcf/d in the prior-year period and 275 MMcf/d in the first quarter of 2017. Volume throughput for the second quarter of 2017 increased relative to the prior-year period due to our customers' completion of six new wells behind the system in the first quarter of 2017 and another five new wells in the second quarter of 2017. In addition, in April 2017, we commissioned the TPL-7 connector project, a new pipeline designed to offload capacity constrained natural gas from a third-party gathering system adjacent to the SMU system. This project significantly increased volumes across SMU in the second quarter of 2017.

We have one drilling rig currently running behind our SMU system and we expect that our customers will complete another four wells behind the SMU system in the second half of 2017.

Ohio Gathering

The Ohio Gathering reportable segment includes our 40% ownership interest in Ohio Gathering, a natural gas gathering system spanning the condensate, liquids-rich and dry gas windows of the Utica Shale in Harrison, Guernsey, Noble, Belmont and Monroe counties in southeastern Ohio. This segment also includes our 40% ownership interest in Ohio Condensate, a condensate stabilization facility located in Harrison County, Ohio. Segment adjusted EBITDA for the Ohio Gathering segment includes our proportional share of adjusted EBITDA from Ohio Gathering and Ohio Condensate, based on a one-month lag.

Segment adjusted EBITDA for the first quarter of 2017 totaled $9.6 million, down 24.5% from $12.7 million for the prior-year period, primarily due to lower volume throughput on Ohio Gathering and lower stabilization revenue at Ohio Condensate. Segment adjusted EBITDA for the second quarter of 2017 was also negatively impacted by higher operating expenses related to compressor overhauls in the quarter. Volume throughput on the Ohio Gathering system, which is based on a one-month lag, averaged 706 MMcf/d, gross, in the second quarter of 2017 compared to 937 MMcf/d, gross, in the prior-year period and 769 MMcf/d, gross, in the first quarter of 2017. Volume throughput on Ohio Gathering in the second quarter of 2017 was impacted by natural production declines from existing wells on the system and was partially offset by volumes from 10 new condensate wells that were commissioned during the quarter. Dry natural gas volumes on the Ohio Gathering system were favorably impacted by the commissioning of the Larew Compressor Station in March 2017 which lowered pressures across the dry gas system and facilitated increased volumes.

Our customers are currently running two drilling rigs in Ohio Gathering's operating footprint. We expect to see the production volume increase beginning in the third quarter of 2017 based on our customers running five drilling rigs across the Ohio Gathering system in the first five months of 2017.

Williston Basin

The Bison Midstream, Polar and Divide and Tioga Midstream systems provide our midstream services for the Williston Basin reportable segment. Bison Midstream gathers associated natural gas production in Mountrail and Burke counties in North Dakota and delivers to third-party pipelines serving a third-party processing plant in Channahon, Illinois. The Polar and Divide system gathers crude oil production in Williams and Divide counties in North Dakota and delivers to the COLT and Basin Transload rail terminals, as well as other third-party, intra- and interstate pipelines. The Polar and Divide system also gathers and delivers produced water to various third-party disposal wells in the region. Tioga Midstream is a crude oil, produced water and associated natural gas gathering system in Williams County, North Dakota. All crude oil and natural gas gathered on the Tioga Midstream system is delivered to third-party pipelines, and all produced water is delivered to third-party disposal wells.

Segment adjusted EBITDA for the Williston Basin segment totaled $17.2 million for the second quarter of 2017 compared to $19.2 million for the prior-year period. Compared to the prior-year period, second quarter 2017 volumes were negatively impacted due to a lack of new well completions behind our gathering systems during the quarter. In addition to lower volumes, a certain Williston customer has gathering rates that reset lower in July 2016 which negatively impacted our year-over-year comparisons. The Williston Basin segment benefitted in the second quarter of 2017 from the recognition of $2.8 million of gathering revenue related to (i) gathering services fees from previously billed but unearned revenue, and (ii) crude oil and produced water volumes that a customer trucked around our gathering system in the second half of 2016.

Liquids volumes averaged 68.9 Mbbl/d in the second quarter of 2017, a decrease of 19.9% over the prior-year period and a decrease of 9.8% compared to the first quarter of 2017. Lower liquids volumes were primarily related to natural production declines from existing wells on the Polar and Divide system as six new wells were completed late in the second quarter of 2017. Certain of our customers remain active across the Polar and Divide system, with four drilling rigs currently working and adding to an existing backlog of approximately 40 drilled uncompleted wells ("DUCs") currently behind our Polar and Divide gathering system. We expect many of these DUCs to begin to be completed over the next several months. Overall, we expect the pace of well completions by our customers on the Polar and Divide system to be slower than originally anticipated.

Associated natural gas volumes averaged 20 MMcf/d in the second quarter of 2017, a decrease of 16.7% over the prior-year period and up 17.6% from the first quarter of 2017. Relative to the prior-year period, volume declines were primarily related to natural production declines from existing wells on the Bison Midstream and Tioga Midstream systems as no new wells were connected during the quarter. Volumes increased relative to the first quarter of 2017 due to the severe winter weather that impacted natural gas volumes in this segment in the first quarter of 2017.

Piceance/DJ Basins

The Grand River and the Niobrara G&P systems provide our midstream services for the Piceance/DJ Basins reportable segment. These systems provide natural gas gathering and processing services for producers operating in the Piceance Basin located in western Colorado and eastern Utah and in the Denver-Julesburg ("DJ") Basin located in northeastern Colorado.

Segment adjusted EBITDA totaled $27.3 million for the second quarter of 2017, an increase of 4.0% from $26.2 million for the prior-year period. Second quarter 2017 volume throughput averaged 596 MMcf/d, an increase of 5.7% from 564 MMcf/d in the prior-year period and a decrease of 3.1% from 615 MMcf/d in the first quarter of 2017. Volume growth relative to the prior-year period was primarily due to ongoing drilling and completion activity from our single-basin focused, private equity-backed customers. These customers commissioned dozens of new wells across our Piceance and DJ Basin gathering systems in 2016, and in the first quarter of 2017, these customers commissioned another 31 new wells; seven new wells were commissioned behind our systems late in the second quarter of 2017. This activity was partially offset by the impact of our anchor customer's continued suspension of drilling activities in the basin and the resulting natural declines from existing production. This impact of our anchor customer's volume declines was partially offset by higher minimum volume commitment ("MVC") shortfall payment adjustments associated with our gas gathering agreements. Certain of our customers remain active across our Piceance and DJ gathering systems with four drilling rigs currently working. We expect drilling levels to increase and volume growth to follow as a result of Caerus' recent acquisition of Encana's acreage in the Piceance Basin.

Barnett Shale

The DFW Midstream system provides our midstream services for the Barnett Shale reportable segment. This system gathers and delivers low-pressure natural gas received from pad sites, primarily located in southeastern Tarrant County, Texas, to downstream intrastate pipelines serving various natural gas hubs in the region.

Segment adjusted EBITDA for the Barnett Shale segment totaled $13.0 million for the second quarter of 2017, a decrease of 6.6% from the prior-year period. Volume throughput of 271 MMcf/d in the second quarter of 2017 was down 20.5% compared to the prior-year period average of 341 MMcf/d and down 5.2% from 286 MMcf/d in the first quarter of 2017. No new wells were completed behind the DFW gathering system in the second quarter of 2017, but two of our customers resumed drilling activity behind the DFW system beginning in April 2017. The two new rigs were added by single basin-focused, private equity-backed customers who acquired the underlying acreage in the last 18 months. Two workover rigs also continue to operate behind our system and return several dormant wells to service. We expect this workover activity will continue across the second half of 2017 and, together with the expected completions of the new wells currently being drilled, will increase volume throughput beginning in the fourth quarter of 2017.

Marcellus Shale

The Mountaineer Midstream system provides our midstream services for the Marcellus Shale reportable segment. This system gathers high-pressure natural gas received from upstream pipeline interconnections with Antero Midstream Partners, LP and Crestwood Equity Partners LP. Natural gas on the Mountaineer Midstream system is delivered to the Sherwood Processing Complex located in Doddridge County, West Virginia.

Segment adjusted EBITDA for the Marcellus Shale segment totaled $5.4 million for the second quarter of 2017, an increase of 13.3% from $4.8 million for the prior-year period, primarily due to an increase in volume throughput, partially offset by $0.5 million of right-of-way repair expenses incurred during the quarter. Volume throughput for this segment averaged 480 MMcf/d in the second quarter of 2017, an increase of 15.4% from 416 MMcf/d in the prior-year period, and an increase of 10.6% from 434 MMcf/d in the first quarter of 2017. Volume throughput increased relative to the first quarter of 2017 as a result of our customer completing 11 new wells behind our system. Although there are no rigs currently working behind our system, we expect our customer to continue to complete its inventory of DUCs behind the Mountaineer Midstream system throughout the balance of the year, which we expect to drive volumes higher in the third and fourth quarter of 2017.

MVC Shortfall Payments

SMLP billed its customers $9.0 million in the second quarter of 2017 related to MVCs. For those customers that do not have credit banking mechanisms in their gathering agreements, or do not have the ability to use MVC shortfall payments as credits, the MVC shortfall payments are accounted for as gathering revenue in the period that they are earned. For the second quarter of 2017, SMLP recognized $10.2 million of gathering revenue associated with MVC shortfall payments from certain customers in the Williston Basin, Piceance/DJ Basins, Barnett Shale and Marcellus Shale reportable segments.

MVC shortfall payment adjustments in the second quarter of 2017 totaled $5.6 million and included ($1.2) million of deferred revenue related to MVC shortfall payments and $6.8 million related to MVC shortfall payment adjustments from certain customers in the Piceance/DJ Basins, Williston Basin and Barnett Shale reportable segments.

SMLP's MVC shortfall payment mechanisms contributed $15.7 million of adjusted EBITDA in the second quarter of 2017.

                     due to equity method

Capital Expenditures

Capital expenditures totaled $42.2 million in the second quarter of 2017, including $10.7 million of contributions to equity method investees and maintenance capital expenditures of approximately $5.9 million. Development activities during the second quarter of 2017 were primarily related to the ongoing expansion of our Summit Midstream Utica natural gas gathering system as well as the continued development of certain pipeline and compression expansion projects in the Williston and Piceance/DJ Basins segment.

Capital & Liquidity

As of June 30, 2017, SMLP had $759.0 million of available borrowing capacity under its $1.25 billion revolving credit facility, subject to covenant limits. Based upon the terms of SMLP's revolving credit facility and total outstanding debt of $1.291 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 June 30, 2017 were 4.35 to 1.0 and 1.65 to 1.0, respectively.

In May 2017, SMLP executed an amendment and extension of its $1.25 billion revolving credit facility. The maturity date of the revolving credit facility was extended by approximately 3.5 years, from November 2018 to May 2022. The facility includes a $250.0 million accordion and has the same pricing and a similar covenant package to the previous facility. The total leverage ratio financial covenant, as defined in the credit agreement, was increased from 5.00 to 1.00 to 5.50 to 1.00 in exchange for including a new senior secured leverage ratio financial covenant of 3.75 to 1.00.

During the second quarter of 2017, SMLP issued 745,848 common units under its $150.0 million At-The-Market program raising gross proceeds of $17.3 million.

Deferred Purchase Price Obligation

The consideration for the 2016 Drop Down consisted of (i) an initial $360.0 million cash payment (the "Initial Payment") which was funded on March 3, 2016 with borrowings under SMLP's revolving credit facility and (ii) a deferred payment which will be paid no later than December 31, 2020 (the "Deferred Purchase Price Obligation" or the "Deferred Payment," as defined below). At the discretion of the board of directors of SMLP's general partner, the Deferred Payment can be made in either cash or SMLP common units, or a combination thereof.

The Deferred Payment will be equal to: (a) six-and-one-half (6.5) multiplied by the average Business Adjusted EBITDA of the 2016 Drop Down Assets for 2018 and 2019; less (b) the Initial Payment; less (c) all capital expenditures incurred for the 2016 Drop Down Assets between March 3, 2016 and December 31, 2019; plus (d) all Business Adjusted EBITDA from the 2016 Drop Down Assets between March 3, 2016 and December 31, 2019. SMLP currently estimates that the undiscounted future value of the Deferred Payment will be approximately $800.0 million.

Quarterly Distribution

On July 27, 2017, the board of directors of SMLP's general partner declared a quarterly cash distribution of $0.575 per unit on all of its outstanding common units, or $2.30 per unit on an annualized basis, for the quarter ended June 30, 2017. This quarterly distribution remains unchanged from the previous quarter and from the quarter ended June 30, 2016. This distribution will be paid on August 14, 2017, to unitholders of record as of the close of business on August 7, 2017.

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, unit-based and noncash compensation, Deferred Purchase Price Obligation, early extinguishment of debt expense, impairments 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, 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.

Adjusted EBITDA is used to assess:

    --  the ability of our assets to generate cash sufficient to make cash
        distributions and support our indebtedness;
    --  the financial performance of our assets without regard to financing
        methods, capital structure or historical cost basis;
    --  our operating performance and return on capital as compared to those of
        other entities in the midstream energy sector, without regard to
        financing or capital structure;
    --  the attractiveness of capital projects and acquisitions and the overall
        rates of return on alternative investment opportunities; and
    --  the financial performance of our assets without regard to (i) income or
        loss from equity method investees, (ii) the impact of the timing of
        minimum volume commitments shortfall payments under our gathering
        agreements or (iii) the timing of impairments or other noncash income or
        expense items.

Distributable cash flow is used to assess:

    --  the ability of our assets to generate cash sufficient to make future
        cash distributions and
    --  the attractiveness of capital projects and acquisitions and the overall
        rates of return on alternative investment opportunities.

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:

    --  certain items excluded from adjusted EBITDA and distributable cash flow
        are significant components in understanding and assessing an entity's
        financial performance, such as an entity's cost of capital and tax
        structure;
    --  adjusted EBITDA and distributable cash flow do not reflect our cash
        expenditures or future requirements for capital expenditures or
        contractual commitments;
    --  adjusted EBITDA and distributable cash flow do not reflect changes in,
        or cash requirements for, our working capital needs; and
    --  although depreciation and amortization are noncash charges, the assets
        being depreciated and amortized will often have to be replaced in the
        future, and adjusted EBITDA and distributable cash flow do not reflect
        any cash requirements for such replacements.

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, (ii) deferred purchase price obligation and (iii) 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.
