Overview

We are a value-driven limited partnership focused on developing, owning and operating midstream energy infrastructure assets that are strategically located in unconventional resource basins, primarily shale formations, in the continental United States.



We classify our midstream energy infrastructure assets into two categories, our
Core Focus Areas and our Legacy Areas. Further details on our Focus Areas and
Legacy Areas are summarized below.

• Core Focus Areas. Core producing areas of basins in which we expect our

gathering systems to experience greater long-term growth, driven by our

customers' ability to generate more favorable returns and support sustained

drilling and completion activity in varying commodity price environments. In

the near-term, we expect to concentrate the majority of our capital

expenditures in our Core Focus Areas. Our Utica Shale, Ohio Gathering,

Williston Basin, DJ Basin and Permian Basin reportable segments (as
      described below) comprise our Core Focus Areas.



• Legacy Areas. Production basins in which we expect volume throughput on our

gathering systems to experience relatively lower long-term growth compared

to our Core Focus Areas, given that our customers require relatively higher

commodity prices to support drilling and completion activities in these

basins. Upstream production served by our gathering systems in our Legacy

Areas is generally more mature, as compared to our Core Focus Areas, and the

decline rates for volume throughput on our gathering systems in the Legacy

Areas are typically lower as a result. We expect to continue to decrease our

near-term capital expenditures in these Legacy Areas. Our Piceance Basin,

Barnett Shale and Marcellus Shale reportable segments (as described below)


      comprise our Legacy Areas.




Our financial results are driven primarily by volume throughput across our
gathering systems and by expense management. We generate the majority of our
revenues from the gathering, compression, treating and processing services that
we provide to our customers. A majority of the volumes that we gather, compress,
treat and/or process have a fixed-fee rate structure which enhances the
stability of our cash flows by providing a revenue stream that is not subject to
direct commodity price risk. We also earn a portion of our revenues from the
following activities that directly expose us to fluctuations in commodity
prices: (i) the sale of physical natural gas and/or NGLs purchased under
percentage-of-proceeds or other processing arrangements with certain of our
customers in the Williston Basin, Piceance Basin, and Permian Basin segments,
(ii) the sale of natural gas we retain from certain Barnett Shale customers and
(iii) the sale of condensate we retain from our gathering services in the
Piceance Basin segment. During the year ended December 31, 2020, these
additional activities accounted for approximately 13% of total revenues.

We also have indirect exposure to changes in commodity prices in that
persistently low commodity prices may cause our customers to delay and/or cancel
drilling and/or completion activities or temporarily shut-in production, which
would reduce the volumes of natural gas and crude oil (and associated volumes of
produced water) that we gather. If certain of our customers cancel or delay
drilling and/or completion activities or temporarily shut-in production, the
associated MVCs, if any, ensure that we will earn a minimum amount of revenue.

--------------------------------------------------------------------------------

Table of Contents

Key Matters for the Year ended December 31, 2020. The following items are reflected in our financial results for the fiscal year ended December 31, 2020:

• GP Buy-In Transaction. In May 2020, the Partnership completed the GP Buy-In

Transaction whereby the Partnership acquired from its then private equity

sponsor, ECP, (i) Summit Investments, which indirectly owned the

Partnership's General Partner, (ii) through its ownership of SMP Holdings,

3,415,646 of its common units and (iii) a deferred purchase price obligation

receivable owed by the Partnership. Consideration paid to ECP included a

$35.0 million cash payment and warrants to purchase up to 666,667 common

units. In connection with the closing of the GP Buy-In Transaction, ECP's

management resigned from the Board of Directors and fully exited its

investment in the Partnership (other than retaining the aforementioned


      warrants). Refer to Note 1 - Organization, Business Operations and
      Presentation and Consolidation for details.

• Suspension of common and preferred unit distributions. In May 2020, and in

conjunction with the GP Buy-In Transaction, the Partnership suspended

distributions to holders of its common units and its Series A Preferred

Units, commencing with respect to the quarter ending March 31, 2020. The

suspension of distributions enabled the Partnership to retain an incremental

$76 million per annum of operating cash flow and reallocate this retained

cash to indebtedness reduction, liability management transactions and other


      corporate initiatives. The unpaid cash distributions on the Series A
      Preferred Units continue to accrue semi-annually, until paid.

July 2020 Series A Preferred Unit Exchange. In July 2020, the Partnership

completed the Preferred Exchange Offer, whereby it issued 837,547 SMLP

common units in exchange for 62,816 Series A Preferred Units. Upon closing

the Preferred Exchange Offer, it eliminated $66.5 million of the Series A

Preferred Unit liquidation preference amount, inclusive of $3.7 million of

accrued distributions due as of the settlement date.

• Open Market Repurchase of Senior Notes. Throughout 2020, the Partnership

completed its Open Market Repurchases, which resulted in the extinguishment

of $32.4 million of face value of the 2022 Senior Notes and $201.8 million


      of face value of the 2025 Senior Notes. Total cash consideration paid to
      repurchase the principal amounts outstanding of the 2022 Senior Notes and
      2025 Senior Notes, plus accrued interest totaled $150.3 million and the
      Partnership recognized a $86.4 million gain on the extinguishment of debt
      related to these Open Market Repurchases during 2020.

• Debt Tender Offers. In September 2020, the Co-Issuers completed the Debt

Tender Offers to purchase a portion of their 2022 Senior Notes and 2025

Senior Notes. Upon completion of the Debt Tender Offers, the Co-Issuers


      repurchased $33.5 million principal amount of the 2022 Senior Notes
      and $38.7 million principal amount of the 2025 Senior Notes. Total cash
      consideration paid to repurchase the principal amounts outstanding of the

2022 and 2025 Senior Notes, plus accrued interest, totaled $48.7 million,

and the Partnership recognized a $23.3 million gain on the extinguishment of

debt related to the Debt Tender Offers during 2020.




   •  TL Restructuring. In November 2020, the Partnership completed the TL
      Restructuring. All of the Term Loan Lenders participated in the TL
      Restructuring. As part of the TL Restructuring, the Partnership paid SMP

Holdings $26.5 million in cash as consideration to fully settle the deferred

purchase price obligation, which SMP Holdings then paid to the Term Loan

Lenders. In addition, the Term Loan Lenders executed the Strict Foreclosure

on the 2,306,972 common units pledged as collateral under the SMPH Term Loan

in full satisfaction of SMP Holdings' outstanding obligations under the SMPH

Term Loan.

December 2020 Series A Preferred Unit Tender. On December 29, 2020, the

Partnership completed the Preferred Tender Offer, whereby it accepted 75,075


      Series A Preferred Units for a purchase price of $333.00 per Series A
      Preferred Unit and an aggregate purchase price of $25.0 million. Upon
      closing the Preferred Tender Offer, it eliminated $82.7 million of the

Series A Preferred Unit liquidation preference due as of the settlement

date, inclusive of $7.6 million of accrued distributions.

Double E Project. For the year ended December 2020, the Partnership's

proportionate share of capital calls due in 2020 totaled $99.9 million,

which includes $2.7 million in capitalized interest, and was funded with

$20.6 million of Partnership generated funds and the issuance of $85.3

million of Subsidiary Series A Preferred Units.

• 2020 Restructuring Costs. In the fourth quarter of 2020, we completed an

internal initiative to evaluate and transform our cost structure, enhance

margins and improve our competitive position in response to COVID-19 and the

related weakening of the economy. For the year ended December 31, 2020, we

incurred approximately $5.6 million in restructuring costs relating to this


      initiative (included in general and administrative expense).

• 2020 Impairments. In the fourth quarter of 2020, we recorded $8.6 million of

impairments related to certain long-lived assets, of which $5.1 million


      related to a January 2021 sale of compressor equipment for a total cash
      purchase price of $8.0 million.

Key Matters for the Year ended December 31, 2019. The following items are reflected in our financial results for the fiscal year ended 2019:

• Equity Method Investment Impairment. In December 2019, we identified certain

triggering events which indicated that our equity method investment in Ohio

Gathering could be impaired. We completed an other-than-temporary impairment

analysis to determine the potential equity method impairment charge to be

recorded on our consolidated financial statements. As a result, an

impairment charge of approximately $329.7 million was recorded in the loss


      from equity method investees caption on the consolidated statement of
      operations.

• Goodwill Impairment. In September 2019, in connection with our annual

impairment evaluation, we determined that the fair value of the Mountaineer

Midstream reporting unit did not exceed its carrying value and we recognized

a goodwill impairment charge of $16.2 million.

• Disposition. In March 2019, we identified certain triggering events which

indicated that certain long-lived assets in the DJ Basin and Barnett Shale

reporting segments could be impaired. Consequently, we performed a

recoverability assessment of certain assets within these reporting segments.

In the DJ Basin, we determined certain processing plant assets related to

our 20 MMcf/d plant would no longer be operational due to our expansion

plans for the Niobrara G&P system and we recorded an impairment charge of

$34.7 million related to these assets. In the Barnett Shale, we determined

certain compressor station assets would be shut down and de-commissioned and

we recorded an impairment charge of $9.7 million related to these assets.

Double E Project. In June 2019, we continued development of the Double E

Project after securing firm 10-year commitments under binding precedent

agreements for a substantial majority of the pipeline's initial throughput

capacity of 1.35 Bcf of gas per day and executing the joint venture

agreement (described below) with an affiliate of Double E's foundation

shipper. The Double E Project, which consists of an approximately 116-mile


      mainline and related facilities, will provide interstate natural gas
      transportation service from the Delaware Basin production area to the Waha
      Hub in Texas.

• Summit Permian Transmission. In connection with the Double E Project, Summit

Permian Transmission contributed total assets of approximately $23.6 million

for a 70% ownership interest in Double E. Concurrent with this contribution,

Double E distributed $7.3 million to the Partnership.

• Double E Financing. In December 2019, as part of our financing for the

Double E Project, we formed Permian Holdco, a newly created, unrestricted

subsidiary of SMLP that indirectly owns SMLP's 70% interest in Double E. In

connection with the formation of Permian Holdco, we entered into an

agreement with TPG Energy Solutions Anthem, L.P. ("TPG") on December 24,

2019 to fund up to $80 million of Permian Holdco's future capital calls

associated with the Double E Project. Simultaneously, on December 24, 2019,

Permian Holdco issued 30,000 Subsidiary Series A Preferred Units to TPG for

net proceeds of $27.4 million.

• Red Rock. In December 2019, Red Rock Gathering and certain affiliates of

SMLP (collectively, "the Red Rock Parties") entered into a Purchase and Sale

Agreement (the "Red Rock PSA") pursuant to which the Red Rock Parties agreed

to sell certain Red Rock Gathering system assets for a cash purchase price

of $12.0 million (the "Red Rock Sale"). Prior to closing, we recorded an

impairment charge of $14.2 million based on the expected consideration and

the carrying value for the Red Rock Gathering system assets. On December 2,

2019, we closed the Red Rock Sale. The impairment is included in the

Long-lived asset impairment caption on the consolidated statement of

operations. The financial contribution of these assets (a component of the

Piceance Basin reportable segment) are included in our consolidated
      financial statements and footnotes for the period from January 1, 2019
      through December 1, 2019.

• Tioga Midstream. Until March 22, 2019, we owned Tioga Midstream, a crude

oil, produced water and associated natural gas gathering system in the

Williston Basin. On March 22, 2019, we sold the Tioga Midstream system to

affiliates of Hess Infrastructure Partners LP for a combined cash purchase

price of approximately $90 million and recorded a gain on sale of $0.9

million based on the difference between the consideration received and the

carrying value for Tioga Midstream at closing. The gain is included in the


      Gain on asset sales, net caption on the consolidated statement of
      operations. The financial results of Tioga Midstream (a component of the
      Williston Basin reportable segment) are included in our consolidated

financial statements and footnotes for the historical periods through March


      22, 2019. Refer to Note 18 to the consolidated financial statements for
      details on the sale of Tioga Midstream.

• 2019 Restructuring Costs. In the third quarter of 2019, we began an internal

initiative to evaluate and transform our cost structure, enhance margins and

improve our competitive position in response to a weakening commodity price

backdrop. For the year ended December 31, 2019, we incurred approximately

$5.0 million in restructuring costs relating to this initiative (included in

general and administrative expense). For the year ended December 31, 2020,

we incurred an additional $3.5 million related to this initiative.

Trends and Outlook

Our business has been, and we expect our future business to continue to be, affected by the following key trends:

• Ongoing impact of the COVID-19 pandemic and reduced demand and prices for


      oil;


  • Natural gas, NGL and crude oil supply and demand dynamics;


  • Production from U.S. shale plays;


  • Capital markets availability and cost of capital; and


  • Shifts in operating costs and inflation.

Our expectations are based on assumptions made by us and information currently available to us. To the extent our underlying assumptions about, or interpretations of, available information prove to be incorrect, our actual results may vary materially from our expected results.



Ongoing impact of the COVID-19 pandemic and reduced demand and prices for oil.
We are closely monitoring the impact of the outbreak of COVID-19 on all aspects
of our business, including how it has impacted and will impact our customers,
employees, supply chain and distribution network. We are unable to predict the
ultimate impact that COVID-19 and related factors may have on our business,
future results of operations, financial position or cash flows. Given the
dynamic nature of the COVID-19 pandemic and related market conditions, we cannot
reasonably estimate the period of time that these events will persist or the
full extent of the impact they will have on our business. The extent to which
our operations may be impacted by the COVID-19 pandemic will depend largely on
future developments, which are highly uncertain and cannot be accurately
predicted, including changes in the severity of the pandemic, countermeasures
taken by governments, businesses and individuals to slow the spread of the
pandemic, and the development and availability of treatments and vaccines and
the extent to which these treatments and vaccines may remain effective as
potential new strains of the coronavirus emerge. Furthermore, the impacts of a
potential worsening of global economic conditions and the continued disruptions
to and volatility in the financial markets remain unknown.

In response to the COVID-19 pandemic, we have modified our business practices,
including restricting employee travel, modifying employee work locations,
implementing social distancing and enhancing sanitary measures in our
facilities. Many of our suppliers, vendors and service providers have made
similar modifications. The resources available to employees working remotely may
not enable them to maintain the same level of productivity and efficiency, and
these and other employees may face additional demands on their time. Our
increased reliance on remote access to our information systems increases our
exposure to potential cybersecurity breaches. We may take further actions as
government authorities require or recommend or as we determine to be in the best
interests of our employees, customers, partners and suppliers. There is no
certainty that such measures will be sufficient to mitigate the risks posed by
the virus, in which case our employees may become sick, our ability to perform
critical functions could be impaired, and we may be unable to respond to the
needs of our business. The resumption of normal business operations after such
interruptions may be delayed or constrained by lingering effects of COVID-19 on
our suppliers, third-party service providers, and/or customers.

In addition to the significant reduction in global demand for oil and natural
gas caused by the economic effects of the COVID-19 pandemic, there were also
volatile oil prices during 2020 largely due to a supply and demand imbalance and
actions by members of OPEC and other foreign, oil-exporting countries. This
disrupted the oil and natural gas exploration and production industry and other
industries that serve exploration and production companies. These industry
conditions, coupled with those resulting from the COVID-19 pandemic, could lead
to significant global economic contraction generally and in our industry in
particular.

Over the past several months, we have collaborated extensively with our customer base regarding production reductions and delays to drilling and completion activities in light of the current commodity price backdrop and COVID-19 pandemic. Given


                                       74

--------------------------------------------------------------------------------

Table of Contents

continued volatility in market conditions since March 2020, and based on recently updated production forecasts and 2021 development plans from our customers, we currently expect our 2021 results to be affected by decreased drilling activity.



Natural gas, NGL and crude oil supply and demand dynamics. Natural gas continues
to be a critical component of energy supply and demand in the United States. The
average spot price of natural gas decreased by approximately 21% from 2020 to
2019, primarily due to natural gas supply exceeding demand. The average daily
Henry Hub Natural Gas Spot Price was $2.03 per MMBtu during 2020, compared with
$2.56 per MMBtu during 2019. Henry Hub closed at $2.36 per MMBtu on December 31,
2020. As of February 18, 2021, Henry Hub 12-month strip pricing closed at $3.11
per MMBtu. Natural gas prices continue to trade at lower-than-average historical
prices due in part to increased natural gas production and an elevated level of
natural gas in storage in the continental United States. The average amount of
working natural gas in underground storage in the continental U.S. was 3.05 Tcfe
in 2020, which was 23.4% higher than in 2019. In the near term, we believe that
until the supply of natural gas in storage has been reduced, natural gas prices
are likely to remain constrained. Over the long term, we believe that the
prospects for continued natural gas demand are favorable and will be driven
primarily by global population and economic growth, as well as the continued
displacement of coal-fired electricity generation by natural gas-fired
electricity generation. However, we note that over the last several years there
has been an increasing societal opposition to the production of hydrocarbons
generally, which may be reflected in legislation, executive orders or
regulations that may significantly restrict the domestic production of fossil
fuels, including natural gas.

In addition, certain of our gathering systems are directly affected by crude oil
supply and demand dynamics. Crude oil prices decreased in 2020, with the average
daily Cushing, Oklahoma West Texas Intermediate crude oil spot price decreasing
from an average $56.99 per barrel during 2019 to an average of $39.16 per barrel
during 2020, representing a 31.3% decrease, reflecting broader market concerns
for global oil supply and demand dynamics. In response to the general decrease
in crude oil prices, the number of active crude oil drilling rigs in the
continental United States decreased from 677 in December 2019 to 267 in December
2020, according to Baker Hughes. Over the next several years, we expect that
crude oil prices will support continued drilling activity and increasing
production in the Williston Basin, Permian Basin and, given the current
regulatory environment in Colorado, in rural parts of the DJ Basin.

Growth in production from U.S. shale plays. Over the past several years, natural
gas production from unconventional shale resources has increased significantly
due to advances in technology that allow producers to extract significant
volumes of natural gas from unconventional shale plays on favorable economic
terms relative to most conventional plays. In recent years, a number of
producers and their joint venture partners, including large international
operators, industrial manufacturers and private equity sponsors, have committed
significant capital to the development of these unconventional resources,
including the Piceance, Barnett, Bakken, Marcellus, Utica and Permian Basin
shale plays in which we operate, and we believe that these long-term capital
investments will support drilling activity in unconventional shale plays over
the long term.

Rate of growth in production from U.S. shale plays. Some of our producer
customers have adjusted their drilling and completion activities and schedules
to manage drilling and completion costs at levels that are achievable using
internally generated cash flow from their underlying operations. Historically,
as part of a strategy to accelerate production growth, these producers would
raise external capital to fund drilling and completion costs in excess of the
cash flows generated from their underlying assets. In general, we expect our
producer customers to maintain moderate completion and production activities
across many of our systems relative to our previous expectations as a result of
the commodity price environment and a continuation of the general trend of
producers constraining drilling and completion activity to levels that can be
satisfied with internally generated cash flow.

Capital markets availability and cost of capital. Credit markets were volatile
throughout 2019, as borrowing costs increased and investors assessed the impact
of rising rates on broader economic activity. Capital markets conditions,
including but not limited to availability and higher borrowing costs, could
affect our ability to access the debt capital markets to the extent necessary,
to fund our future growth. Furthermore, market demand for equity issued by
master limited partnerships has been significantly lower in recent years than it
has been historically, which may make it more challenging for us to finance our
capital expenditures with the issuance of additional equity. We announced the
elimination of our common unit distribution in May 2020 beginning with the
distribution paid in respect of the second quarter of 2020, and this action may
further reduce demand for our common units. In addition, interest rates on
future credit facilities and debt offerings could be higher than current levels,
causing our financing costs to increase accordingly.

Shifts in operating costs and inflation. Throughout most of the last five years,
high levels of crude oil and natural gas exploration, development and production
activities across the United States resulted in increased competition for
personnel and equipment as well as higher prices for labor, supplies, equipment
and other services. Beginning in 2015, this dynamic began to shift as prices for
crude oil and natural gas-related services decreased in line with overall
decline in demand for these goods and services. While we expect lower
service-related costs in the near term, we expect that over the longer term,
these costs will continue to have a high correlation to changes in the
prevailing price of crude oil and natural gas.

How We Evaluate Our Operations



We conduct and report our operations in the midstream energy industry through
eight reportable segments: Utica Shale, Ohio Gathering, Williston Basin, DJ
Basin, Permian Basin, Piceance Basin, Barnett Shale, and Marcellus Shale. Each
of our reportable segments provides midstream services in a specific geographic
area and our reportable segments reflect the way in which we internally report
the financial information used to make decisions and allocate resources in
connection with our operations (see Note 20 to the consolidated financial
statements). Our management uses a variety of financial and operational metrics
to analyze our consolidated and segment performance and we view these metrics as
important factors in evaluating our profitability. These metrics include (i)
throughput volume, (ii) revenues, (iii) operation and maintenance expenses, and
(iv) segment adjusted EBITDA.

Throughput Volume



The volume of (i) natural gas that we gather, compress, treat and/or process and
(ii) crude oil and produced water that we gather depends on the level of
production from natural gas or crude oil wells connected to our gathering
systems. Aggregate production volumes are impacted by the overall amount of
drilling and completion activity. Furthermore, because the production rate of
natural gas and crude oil wells decline over time, production can only be
maintained or increased by new drilling or other activity.

As a result, we must continually obtain new supplies of production to maintain
or increase the throughput volume on our systems. Our ability to maintain or
increase throughput volumes from existing customers and obtain new supplies of
throughput is impacted by:

• successful drilling activity within our AMIs;

• the level of work-overs and recompletions of wells on existing pad sites to


      which our gathering systems are connected;


  • the number of new pad sites in our AMIs awaiting connections;

• our ability to compete for volumes from successful new wells in the areas in

which we operate outside of our existing AMIs; and

• our ability to gather, treat and/or process production that has been

released from commitments with our competitors.




We report volumes gathered for natural gas in cubic feet per day. We aggregate
crude oil and produced water gathering and report volumes gathered in barrels
per day.

Revenues

Our revenues are primarily attributable to the volumes that we gather, compress,
treat and/or process and the rates we charge for those services. A majority of
our gathering and processing agreements are fee-based, which limits our direct
exposure to fluctuations in commodity prices. We also have percent-of-proceeds
arrangements with certain customers under which the gathering and processing
revenues that we earn correlate directly with the fluctuating price of natural
gas, condensate and NGLs.

Certain of our gathering and processing agreements contain MVCs pursuant to
which our customers agree to ship or process a minimum volume of production on
our gathering systems, or, in some cases, to pay a minimum monetary amount, over
certain periods during the term of the MVC. These MVCs help us generate stable
revenues and serve to mitigate the financial impact associated with declining
volumes.

Operation and Maintenance Expenses



We seek to maximize the profitability of our operations in part by minimizing,
to the extent appropriate, expenses directly tied to operating our assets.
Direct labor costs, compression costs, ad valorem taxes, repair and
non-capitalized maintenance costs, integrity management costs, utilities and
contract services comprise the most significant portion of our operation and
maintenance expense. Other than utilities expense, these expenses are largely
independent of volumes delivered through our gathering systems but may fluctuate
depending on the activities performed during a specific period.

Segment Adjusted EBITDA



Segment adjusted EBITDA is a supplemental financial measure used by management
and by external users of our financial statements such as investors, commercial
banks, research analysts and others.

                                       77

--------------------------------------------------------------------------------

Table of Contents

Segment 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 other


      companies 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 MVC shortfall

payments under our gathering agreements or (iii) the timing of impairments

or other noncash income or expense items.

Revenues. Total revenues decreased $60.1 million during the year ended December
31, 2020 compared to the prior year primarily comprised of a $24.0 million
decrease in gathering services and related fees and a $37.7 million decrease in
natural gas, NGLs and condensate sales.

Gathering services and related fees. Gathering services and related fees decreased $24.0 million compared to the year ended December 31, 2019, primarily reflecting:

• a $7.2 million decrease in gathering services and related fees in the

Barnett Shale primarily reflecting $7.5 million in lower gas gathering


      revenue attributable to a MVC with a customer in 2019 that expired in 2020.


   •  a $14.7 million decrease in gathering services and related fees in the

Piceance Basin relating to lower volume throughput due to a lack of drilling

and completion activity and natural production declines.

• a $4.6 million increase in gathering services and related fees in the Utica

Shale primarily due to the completion of new wells throughout 2019, and in

2020, and a more favorable volume and gathering rate mix from customers,

partially offset by natural production declines from existing wells.

• a $18.4 million decrease in gathering services and related fees in the

Williston Basin primarily reflecting a decrease in gathering services and

related fees attributable to the sale of the Tioga Midstream system on March

22, 2019, whose 2019 financial results are included for the period from

January 1, 2019 through March 22, 2019 as well as lower liquids volume

throughput, partially offset by the completion of new wells through 2019 and

2020.

• a $1.9 million increase in gathering services and related fees in the DJ

Basin primarily as a result of ongoing drilling and completion activity

across our service area, a more favorable volume and gathering rate mix from

customers and the commissioning of our new natural gas processing plant in

June 2019, partially offset by natural production declines and temporary

production curtailments associated with a significant reduction in crude oil

prices as a result of a decrease in demand attributable to the COVID-19

pandemic.

• a $6.5 million increase in gathering services and related fees in the

Permian Basin primarily as a result of an uptick in customer volumes,

partially offset by natural production declines from wells previously put in

service.

Costs and expenses. Total costs and expenses decreased $76.6 million during the year ended December 31, 2020 compared to the year ended December 31, 2019, primarily reflecting:

• a $31.2 million decrease in long-lived asset impairments in the DJ Basin in

2019.

• a $16.2 million decrease in goodwill impairment charge relating to the

Mountaineer Midstream system in the Marcellus Basin in 2019.

• a $14.2 million decrease in long-lived asset impairments relating to the

sale of certain Red Rock Gathering system assets in the Piceance Basin in

2019.

Cost of natural gas and NGLs. Cost of natural gas and NGLs decreased $26.8 million during the year ended December 31, 2020 compared to the year ended December 31, 2019, primarily driven by lower natural gas, NGL and crude oil marketing activity.



Operation and maintenance. Operation and maintenance expense decreased $12.7
million for the year ended December 31, 2020 compared to the year ended December
31, 2019.

Depreciation and amortization. The increase in depreciation and amortization
expense during 2020 compared to the year ended December 31, 2019 was primarily
due to the assets placed into service in the Permian Basin.

Interest Expense. The decrease in interest expense in the year ended December
31, 2020 compared to the year ended December 31, 2019, was primarily a result of
our liability management initiatives which included our Open Market Repurchases
and Tender Offers, partially offset by a higher outstanding balance on the
Revolving Credit Facility.

Gain on early extinguishment of debt. The $203.1 million gain on the early
extinguishment of debt is primarily related to liability management initiatives
undertaken during 2020 that resulted in a $86.4 million gain from the Open
Market Repurchases, a $23.3 million gain from the Debt Tender Offers, and a
$93.9 million gain from our TL Restructuring. Further details of our liability
management results are summarized below.

Volume throughput increased compared to the year ended December 31, 2020
primarily due to new wells that came online in the fourth quarter of 2019 and
through the first three quarters of 2020. In addition, volume throughput was
impacted by an increase in temporary production curtailments, completion
activity and other operational downtime associated with customers on existing
pad sites.

* Not considered meaningful

Volume throughput for the Ohio Gathering system in 2020 decreased compared to
the year ended December 31, 2019 as a result of natural production declines on
existing wells on the system, fewer well connections, temporary production
shut-ins and was partially offset by the completion of new wells.

Natural gas. Natural gas volume throughput in 2020 increased compared to the
year ended December 31, 2019, primarily reflecting the completion of new wells
behind the Bison Midstream system in the fourth quarter of 2019 and through 2020
partially offset by natural production declines and the sale of Tioga Midstream.

Liquids. Liquids volume throughput in 2020 decreased compared to the year ended
December 31, 2019, primarily associated with natural production declines,
deferral of completion activities, shut-ins and temporary production
curtailments associated with a significant reduction in crude oil prices as a
result of a decrease in demand attributable to the COVID-19 pandemic, partially
offset by the completion of new wells throughout 2019 and 2020.

Total Revenues. Total revenues attributable to Corporate and Other was due to
gathering services, natural gas, and condensate sales. The decrease of $25.0
million compared to the year ended December 31, 2019 was primarily attributable
to the wind down of our marketing group in 2020 as well as lower natural gas
activity.

Cost of Natural Gas and NGLs. Cost of natural gas and NGLs attributable to
Corporate and Other was due to natural gas, NGL and crude oil marketing services
in 2019. The decrease of $26.1 million compared to the year ended December 31,
2019 was attributable to the wind down of our marketing group in 2020.

General and administrative. General and administrative expense attributable to
Corporate and Other increased by $16.5 million, primarily related to a $17.0
million loss contingency accrual in 2020, see note 11 of the consolidated
financial statements for additional information.

Transaction costs. Transaction costs recognized during the year ended December
31, 2020 are primarily related to costs associated with our liability management
initiatives.

Interest Expense. Interest expense decreased $13.1 million compared to the year ended December 31, 2019 primarily as a result of our liability management initiatives which included our Open Market Repurchases and Tender Offers, partially offset by a higher outstanding balance on the Revolving Credit Facility.



Gain on Early Extinguishment of Debt. The gain on the early extinguishment of
debt is primarily related to liability management initiatives undertaken during
2020 that resulted in a $86.4 million gain from the Open Market Repurchases, a
$23.3 million gain from the Debt Tender Offers, and a $93.9 million gain from
our TL Restructuring.

Liquidity and Capital Resources



We depend primarily on funds generated from our operations, our Revolving Credit
Facility, our cash and cash equivalents balance, and capital markets as our
primary sources of liquidity. Looking forward to 2021, we will seek to reduce
indebtedness and extend our indebtedness maturities. As a result, we expect to
fund future expenditures from cash generated by our operations, our Revolving
Credit Facility, our cash equivalents on hand. If optimal, we may also consider
accessing the capital markets, opportunistic divestitures or joint ventures
involving our existing midstream assets.

Debt

Revolving Credit Facility. We have a $1.1 billion senior secured Revolving Credit Facility with a maturity of May 2022 (see Note 9 to the consolidated financial statements). As of December 31, 2020, the outstanding balance of the Revolving Credit Facility was $857.0 million and the unused portion totaled $238.9 million, after giving effect to the issuance thereunder of a $4.1 million


                                       90

outstanding but undrawn irrevocable standby letter of credit. Based on covenant
limits, our available borrowing capacity under the Revolving Credit Facility as
of December 31, 2020 was approximately $105 million. There were no defaults or
events of default during 2020, and as of December 31, 2020, we were in
compliance with the financial covenants in the Revolving Credit Facility. Our
total leverage ratio and senior secured leverage ratio (as defined in the
Revolving Credit Agreement) was 5.1 to 1.0 and 3.2 to 1.0, respectively,
relative to maximum threshold limits of 5.75 to 1.0 and 3.5 to 1.0. Given
further deterioration of market conditions, decreased drilling activity, the
deferral of well completions from customers, limitations on our ability to
access the capital markets at a competitive cost to fund our capital
expenditures and, on a limited scale, temporary production curtailments, we
could have total leverage and senior secured leverage ratios that are higher
than the levels prescribed in the applicable indebtedness agreements. Adverse
developments in our areas of operation could materially adversely impact our
financial condition, results of operations and cash flows. See Note 9 to the
consolidated financial statements for more information on the Revolving Credit
Facility and the issuance of the $4.1 million letter of credit.

2022 Senior Notes. In July 2014, Summit Holdings and its 100% owned finance
subsidiary, Finance Corp. (together with Summit Holdings, the "Co-Issuers")
co-issued $300.0 million of 5.5% senior unsecured notes maturing August 15, 2022
(the "2022 Senior Notes" and, together with the 2025 Senior Notes (defined
below), the "Senior Notes"). As of December 31, 2020, the outstanding balance of
the 2022 Senior Notes is $234.0 million. We pay interest on the 2022 Senior
Notes semi-annually in cash in arrears on February 15 and August 15 of each
year. The 2022 Senior Notes are senior, unsecured obligations and rank equally
in right of payment with all of our existing and future senior obligations. The
2022 Senior Notes are effectively subordinated in right of payment to all
secured indebtedness, to the extent of the collateral securing such
indebtedness. The Co-Issuers may redeem all or part of the 2022 Senior Notes at
a redemption price of 100.000%, plus accrued and unpaid interest, if any. Debt
issuance costs of $5.1 million are being amortized over the life of the 2022
Senior Notes. As of and during the year ended December 31, 2020, we were in
compliance with the financial covenants governing our 2022 Senior Notes.

2025 Senior Notes. In February 2017, the Co-Issuers co-issued $500.0 million of
5.75% senior unsecured notes maturing April 15, 2025 (the "2025 Senior Notes").
As of December 31, 2020, the outstanding balance of the 2025 Senior Notes was
$259.5 million. We pay interest on the 2025 Senior Notes semi-annually in cash
in arrears on April 15 and October 15 of each year. The 2025 Senior Notes are
senior, unsecured obligations and rank equally in right of payment with all of
our existing and future senior obligations. The 2025 Senior Notes are
effectively subordinated in right of payment to all of our secured indebtedness,
to the extent of the collateral securing such indebtedness.

The Co-Issuers may redeem all or part of the 2025 Senior Notes at a redemption
price of 104.313% (with the redemption price declining ratably each April 15 to
100.000% on April 15, 2023), plus accrued and unpaid interest, if any, to, but
not including, the redemption date. Debt issuance costs of $7.7 million are
being amortized over the life of the 2025 Senior Notes. As of and during the
year ended December 31, 2020, we were in compliance with the financial covenants
governing our 2025 Senior Notes.

For additional information on our long-term debt, see Note 9 to the consolidated
financial statements.

(1) The Partnership issued a parental guaranty on behalf of its wholly owned

subsidiary to fund the subsidiary's pro rata share of required Double E

construction project capital calls. As of December 31, 2020, this amount

represents the Partnership's best estimate of its remaining obligation to

fund Double E for the construction of the Double E Project.




  (2) For the purposes of calculating future interest payments we assumed no
      change in balance or rate from December 31, 2020. See Note 9 to the
      consolidated financial statements.

Capital Requirements



Our business is capital intensive, requiring significant investment for the
maintenance of existing gathering systems and the acquisition or construction
and development of new gathering systems and other midstream assets and
facilities. Our Partnership Agreement requires that we categorize our capital
expenditures as either:

• maintenance capital expenditures, which are cash expenditures (including

expenditures for the addition or improvement to, or the replacement of, our

capital assets or for the acquisition of existing, or the construction or

development of new, capital assets) made to maintain our long-term operating

income or operating capacity; or

• expansion capital expenditures, which are cash expenditures incurred for

acquisitions or capital improvements that we expect will increase our

operating income or operating capacity over the long term.




For the year ended December 31, 2020, cash paid for capital expenditures totaled
$43.1 million which included $14.1 million of maintenance capital expenditures.
For the year ended December 31, 2020, we contributed $99.9 million to Double E.

We rely primarily on internally generated cash flow as well as external
financing sources, including commercial bank borrowings and the issuance of
debt, equity and preferred equity securities, and proceeds from asset
divestitures to fund our capital expenditures. We believe that our Revolving
Credit Facility, together with internally generated cash flow and access to debt
or equity capital markets, will be adequate to finance our business for the next
twelve months without adversely impacting our liquidity.

With the completion of our 60 MMcf/d DJ Basin processing plant and compression
expansions in the Permian Basin, capital expenditures began to decline in the
third and fourth quarter of 2019 and continued throughout 2020. We will remain
disciplined with respect to future capital expenditures, which will be primarily
concentrated on the Double E Project and accretive expansions of our existing
systems in our Core Focus Areas. We continue to advance our financing plans for
our equity interest in Double E, which we intend to be credit positive to
Summit. We are currently targeting a financing structure that limits cash
payments by us during 2021, and which shifts a substantial majority of our
Double E capital commitments to third parties, including commercial banks. On
December 24, 2019, we entered into an agreement with TPG to fund up to $80.0
million of Permian Holdco's future capital calls associated with the Double E
Project. For the years ended December 31, 2020 and 2019, Permian Holdco issued
55,251 and 30,000 Subsidiary Series A Preferred Units to TPG for net proceeds of
$48.7 million and $27.4 million, respectively.

We estimate that our 2021 capital program will range from $20.0 million to $35.0 million, including approximately $10.0 million of maintenance capital expenditures.



There are a number of risks and uncertainties that could cause our current
expectations to change, including, but not limited to, (i) the ability to reach
agreement with third parties; (ii) prevailing conditions and outlook in the
natural gas, crude oil and NGL industries and markets and (iii) our ability to
obtain financing from commercial banks, the capital markets, or other financing
sources.

Credit and Counterparty Concentration Risks



We examine the creditworthiness of counterparties to whom we extend credit and
manage our exposure to credit risk through credit analysis, credit approval,
credit limits and monitoring procedures, and for certain transactions, we may
request letters of credit, prepayments or guarantees.

Certain of our customers may be temporarily unable to meet their current
obligations. While this may cause disruption to cash flows, we believe that we
are properly positioned to deal with the potential disruption because the vast
majority of our gathering assets are strategically positioned at the beginning
of the midstream value chain. The majority of our infrastructure is connected
directly to our customers' wellheads and pad sites, which means our gathering
systems are typically the first third-party infrastructure through which our
customers' commodities flow and, in many cases, the only way for our customers
to get their production to market.

We have exposure due to nonperformance under our MVC contracts whereby a
customer, who was not meeting its MVCs, does not have the wherewithal to make
its MVC shortfall payments when they become due. We typically receive payment
for all prior-year MVC shortfall billings in the quarter immediately following
billing. Therefore, our exposure to risk of nonperformance is limited to and
accumulates during the current year-to-date contracted measurement period.

Off-Balance Sheet Arrangements



We may enter into off-balance sheet arrangements and transactions that can give
rise to material off-balance sheet obligations. As of December 31, 2020, our
material off-balance sheet arrangements and transactions include (i) a parental
guaranty issued on behalf of a wholly owned subsidiary to fund the subsidiary's
pro rata share of required Double E Project construction related capital calls,
with the wholly owned subsidiary having an estimated $172.4 million of remaining
capital calls due for construction based on the Partnership's best estimate at
December 31, 2020, (ii) letters of credit outstanding against our Revolving
Credit Facility aggregating to $4.1 million, and (iii) outstanding surety bonds
aggregating to $7.1 million. There are no other transactions, arrangements or
other relationships with unconsolidated entities or other persons that are
reasonably likely to materially affect our liquidity or availability of our
capital resources.

Summarized Financial Information



On March 2, 2020, the SEC issued Final Rule Release No. 33-10762, Financial
Disclosures about Guarantors and Issuers of Guaranteed Securities and Affiliates
Whose Securities Collateralize a Registrant's Securities ("Release 33-10762"),
that amends the disclosure requirements related to certain registered securities
that are guaranteed and those that are collateralized by the securities of an
affiliate.

Under Release 33-10762, an SEC registrant may continue to omit separate
financial statements of subsidiary issuers and guarantors when (1) the
subsidiary issuer is consolidated with the parent company and its security is
either (a) co-issued jointly and severally with the parent company's security or
(b) the subsidiary issuer's security is fully and unconditionally guaranteed by
the parent company and (2) the parent company provides supplemental financial
and non-financial disclosure about the subsidiary issuers and/or guarantors and
the guarantees.

The rules become effective January 4, 2021, with voluntary compliance permitted
immediately. The Senior Notes are fully and unconditionally guaranteed, jointly
and severally, on a senior unsecured basis by SMLP and the Guarantor
Subsidiaries (see Note 9 - Debt). SMLP has concluded that it is eligible to
provide Alternative Disclosures under the amended disclosure requirements and
has early adopted Release 33-10762.

The supplemental summarized financial information below reflects SMLP's separate
accounts, the combined accounts of the Co-Issuers and the Guarantor Subsidiaries
(the Co-Issuers and, together with the Guarantor Subsidiaries, the "Obligor
Group") for the dates and periods indicated. The financial information of the
Obligor Group is presented on a combined basis and intercompany balances and
transactions between the Co-Issuers and Guarantor Subsidiaries have been
eliminated. There were no reportable transactions between the Co-Issuers and
Obligor Group and the subsidiaries that were not issuers or guarantors of the
Senior Notes.

Payments to holders of the Senior Notes are affected by the composition of and
relationships among the Co-Issuers, the Guarantor Subsidiaries and Non-Guarantor
Subsidiaries, who are unrestricted subsidiaries of SMLP and are not issuers or
guarantors of the Senior Notes. The assets of our unrestricted subsidiaries are
not available to satisfy the demands of the holders of the Senior Notes. In
addition, our unrestricted subsidiaries are subject to certain contractual
restrictions related to the payment of dividends, and other rights in favor of
their non-affiliated stakeholders, that limit their ability to satisfy the
demands of the holders of the Senior Notes.
