SUMMIT MIDSTREAM PARTNERS, LP AND SUBSIDIARIES
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
1. ORGANIZATION, BUSINESS OPERATIONS AND PRESENTATION AND CONSOLIDATION
Organization. Summit Midstream Partners, LP (including its subsidiaries, collectively “SMLP” or the “Partnership”) is a Delaware limited partnership that was formed in May 2012 and began operations in October 2012. SMLP is a value-oriented 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. The Partnership’s business activities are primarily conducted through various operating subsidiaries, each of which is owned or controlled by its wholly owned subsidiary holding company, Summit Holdings, a Delaware limited liability company.
Business Operations. The Partnership provides natural gas gathering, compression, treating and processing services as well as crude oil and produced water gathering services pursuant to primarily long-term, fee-based agreements with its customers. The Partnership’s results are primarily driven by the volumes of natural gas that it gathers, compresses, treats and/or processes as well as by the volumes of crude oil and produced water that it gathers. Other than the Partnership’s investments in Double E and Ohio Gathering, all of its business activities are conducted through wholly owned operating subsidiaries.
Presentation and Consolidation. The Partnership prepares its condensed consolidated financial statements in accordance with GAAP as established by the FASB and pursuant to the rules and regulations of the SEC pertaining to interim financial information. The unaudited condensed consolidated financial statements contained in this report include all normal and recurring material adjustments that, in the opinion of management, are necessary for a fair statement of the financial position, results of operations and cash flows for the interim periods presented herein. These unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with the consolidated financial statements and related notes that are included in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2022.
The Partnership makes estimates and assumptions that affect the reported amounts of assets and liabilities at the balance sheet dates, including fair value measurements, the reported amounts of revenues and expenses and the disclosure of commitments and contingencies. Although management believes these estimates are reasonable, actual results could differ from its estimates.
The unaudited condensed consolidated financial statements contained in this report include the assets, liabilities and results of operations of SMLP and its subsidiaries. All intercompany transactions among the consolidated entities have been eliminated in consolidation. Comprehensive income or loss is the same as net income or loss for all periods presented.
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND RECENTLY ISSUED ACCOUNTING STANDARDS APPLICABLE TO THE PARTNERSHIP
There have been no changes to the Partnership’s significant accounting policies since December 31, 2022.
Accounting standards recently implemented.
ASU No. 2020-4 Reference Rate Reform (“ASU 2020-4”). ASU 2020-4 provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by reference rate reform on financial reporting. The amendments in ASU 2020-4 are effective as of March 12, 2020 through December 31, 2022. The Partnership does not expect the provisions of ASU 2020-4 will have a material impact on its consolidated financial statements and disclosures.
New accounting standards not yet implemented.
ASU No. 2020-6 Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815–40) (“ASU 2020-6”). ASU 2020-6 simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. The ASU is part of the FASB’s simplification initiative, which aims to reduce unnecessary complexity in GAAP. The ASU’s amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. The Partnership does not expect the provisions of ASU 2020-6 will have a material impact on its consolidated financial statements and disclosures.
3. ACQUISITIONS AND DIVESTITURES
Acquisition of Outrigger DJ. On December 1, 2022, the Partnership completed the acquisition of 100% of the equity interests of Outrigger DJ Midstream LLC (“Outrigger DJ”) from Outrigger Energy II LLC for cash consideration of $165.0 million, subject to customary working capital adjustments. The acquisition of Outrigger DJ constituted a business combination and was accounted for using the acquisition method of accounting. For tax purposes, the acquisition was accounted for as an acquisition of assets. The acquisition significantly increased the Partnership’s gas processing capacity and footprint in the DJ Basin and diversified its customer base.

7. DEFERRED REVENUE
Certain of the Partnership’s gathering and/or processing agreements provide for monthly or annual MVCs. The amount of the shortfall payment is based on the difference between the actual throughput volume shipped and/or processed for the applicable period and the MVC for the applicable period, multiplied by the applicable gathering or processing fee.
Many of the Partnership’s gas gathering agreements contain provisions that can reduce or delay the cash flows that it expects to receive from MVCs to the extent that a customer's actual throughput volumes are above or below its MVC for the applicable contracted measurement period.
The balances in deferred revenue as of March 31, 2023 and December 31, 2022 are primarily related to contributions in aid of construction which will be recognized as revenue over the life of the contract.

The ABL Facility will mature on May 1, 2026; provided that, (a) if the outstanding amount of the 2025 Senior Notes (or any permitted refinancing indebtedness in respect thereof that has a final maturity, scheduled amortization or any other scheduled repayment, mandatory prepayment, mandatory redemption or sinking fund obligation prior to the date that is 120 days after the Termination Date (as defined in the ABL Agreement)) on such date equals or exceeds $50.0 million, then the ABL Facility will mature on December 13, 2024 and (b) if both (i) any amount of the 2025 Senior Notes (or any permitted refinancing indebtedness in respect thereof that has a final maturity, scheduled amortization or any other scheduled repayment, mandatory prepayment, mandatory redemption or sinking fund obligation prior to the date that is 120 days after the Termination Date) is outstanding on such date and (ii) Liquidity (as defined in the ABL Agreement) is less than an amount equal to the sum of the then aggregate outstanding principal amount of the 2025 Senior Notes (or any permitted refinancing indebtedness in respect thereof that has a final maturity, scheduled amortization or any other scheduled repayment, mandatory prepayment, mandatory redemption or sinking fund obligation prior to the date that is 120 days after the Termination Date) plus the Threshold Amount (as defined in the ABL Agreement) on such date, then the ABL Facility will mature on January 14, 2025.
As of March 31, 2023, the applicable margin under the adjusted LIBOR borrowings was 3.50%, the interest rate was 8.42% and the available borrowing capacity of the ABL Facility totaled $78.7 million after giving effect to the issuance of $4.3 million in outstanding but undrawn irrevocable standby letters of credit.
The ABL Facility requires that Summit Holdings not permit (i) the First Lien Net Leverage Ratio (as defined in the ABL Agreement) as of the last day of any fiscal quarter to be greater than 2.50:1.00, or (ii) the Interest Coverage Ratio (as defined in the ABL Agreement) as of the last day of any fiscal quarter to be less than 2.00:1.00. As of March 31, 2023, the First Lien Net

Leverage Ratio was 1.24:1.00 and the Interest Coverage Ratio was 2.37:1.00 As of March 31, 2023, the Partnership was in compliance with the financial covenants of the ABL Facility.
Permian Transmission Credit Facility. On March 8, 2021, the Partnership’s unrestricted subsidiary, Permian Transmission, entered into a Credit Agreement which allows for $175.0 million of senior secured credit facilities (the “Permian Transmission Credit Facilities”), including a $160.0 million Term Loan Facility and a $15.0 million Working Capital Facility. The Permian Transmission Credit Facilities can be used to finance Permian Transmission’s capital calls associated with its investment in Double E, debt service and other general corporate purposes. Unexpended proceeds from draws on the Permian Transmission Credit Facilities are classified as restricted cash on the accompanying unaudited condensed consolidated balance sheets.
As of March 31, 2023, the applicable margin under adjusted LIBOR borrowings was 2.375%, the interest rate was 6.76% and the unused portion of the Permian Transmission Credit Facilities totaled $4.5 million, subject to a commitment fee of 0.7% after giving effect to the issuance of $10.5 million in outstanding but undrawn irrevocable standby letters of credit. Summit Permian Transmission, LLC entered into interest rate hedges with notional amounts representing approximately 90% of the Permian Term Loan facility at a fixed LIBOR rate of 1.49%. As of March 31, 2023, the Partnership was in compliance with the financial covenants of the Permian Transmission Credit Facilities.
Permian Transmission Term Loan. As described above, in January 2022, the Permian Term Loan Facility was converted into a Term Loan (the “Permian Transmission Term Loan”). The Permian Transmission Term Loan is due January 2028. As of March 31, 2023, the applicable margin under adjusted LIBOR borrowings was 2.375% and the interest rate was 6.76%. As of March 31, 2023, the Partnership was in compliance with the financial covenants governing the Permian Transmission Term Loan.
In accordance with the terms of the Permian Transmission Term Loan, Permian Transmission is required to make mandatory principal repayments. Below is a summary of the remaining mandatory principal repayments as of March 31, 2023:

2026 Secured Notes. In 2021, the Co-Issuers issued $700.0 million of 8.500% Senior Secured Second Lien Notes due 2026 to eligible purchasers pursuant to Rule 144A and Regulation S of the Securities Act, at a price of 98.5% of their face value. Additionally, in November 2022, in connection with the 2022 DJ Acquisitions, the Co-Issuers issued an additional $85.0 million of 2026 Secured Notes at a price of 99.26% of their face value.The Co-Issuers pay interest on the 2026 Secured Notes semi-annually in cash in arrears on April 15 and October 15 of each year, commencing on April 15, 2022, and will be jointly and severally guaranteed, on a senior second-priority secured basis (subject to permitted liens), by the Partnership and each restricted subsidiary of the Partnership (other than the Co-Issuers) that is an obligor under the ABL Agreement, or under the Co-Issuers’ 2025 Senior Notes on the issue date of the 2026 Secured Notes.
The 2026 Secured Notes are effectively subordinated to any of our or the guarantors’ current and future secured first lien indebtedness, including indebtedness incurred under the ABL Facility, to the extent of the value of the collateral securing such indebtedness, and our and the guarantors’ current and future debt that is secured by liens on assets other than the collateral, to the extent of the value of such assets. The 2026 Secured Notes are structurally subordinated to all indebtedness and other liabilities of our subsidiaries that do not guarantee the 2026 Secured Notes. The 2026 Secured Notes are effectively equal to our and the guarantors’ obligations under any future second lien indebtedness and effectively senior to all of our future junior lien indebtedness and existing and future unsecured indebtedness, including our outstanding senior unsecured notes, to the extent of the value of the collateral, and senior to any of our future subordinated indebtedness. The 2026 Secured Notes will mature on October 15, 2026.
Before October 15, 2023, the Co-Issuers may redeem the 2026 Secured Notes, in whole or in part, at a price equal to 100% of their principal amount, plus a make-whole premium, together with accrued and unpaid interest to, but not including the redemption date. On and after October 15, 2023, the Co-Issuers may redeem all or part of the 2026 Secured Notes at redemption prices (expressed as percentages of principal amount) equal to: (a) 104.250% for the twelve-month period beginning October 15, 2023; (b) 102.125% for the twelve-month period beginning October 15, 2024; and (c) 100.000% for the twelve-month period beginning on October 15, 2025 and at any time thereafter, in each case plus accrued and unpaid interest, if any, to, but not including, the redemption date. As of March 31, 2023, the Partnership was in compliance with the financial covenants governing its 2026 Secured Notes.
Starting in the first quarter of 2023 with respect to the fiscal year ended 2022, and continuing annually through the fiscal year ended 2025, the Partnership is required under the terms of the 2026 Secured Notes Indenture to, if it has Excess Cash Flow (as defined in the 2026 Secured Notes Indenture), and subject to its ability to make such an offer under the ABL Facility, offer to purchase an amount of the 2026 Secured Notes, at 100% of the principal amount plus accrued and unpaid interest, equal to
15

Table of Contents
100% of the Excess Cash Flow generated in the prior year. Excess Cash Flow is generally defined as consolidated cash flow minus the sum of capital expenditures and cash payments in respect of permitted investments and permitted restricted payments.
Generally, if the Partnership does not offer to purchase designated annual amounts of its 2026 Secured Notes or reduce its first lien capacity under the 2026 Secured Notes Indenture per annum from 2023 through 2025, the interest rate on the 2026 Secured Notes is subject to certain rate escalations. Per the terms of the 2026 Secured Notes Indenture, the designated amounts are to offer to purchase $50.0 million aggregate principal amount of the 2026 Secured Notes by April 1, 2023, otherwise the interest rate shall automatically increase by 50 basis points per annum; $100.0 million aggregate principal amount of the 2026 Secured Notes by April 1, 2024, otherwise the interest rate shall automatically increase by 100 basis points per annum (minus any amount previously increased); and $200.0 million aggregate principal amount of the 2026 Secured Notes by April 1, 2025, otherwise the interest rate shall automatically increase by 200 basis points per annum (minus any amount previously increased). Based on the amount of the Partnership’s Excess Cash Flow for the fiscal year ended 2022, the Partnership was not able to make offers to purchase in the designated amount for the fiscal year ended 2022; as a result, the interest rate on the 2026 Secured Notes increased 50 basis points to 9.00% effective with the first payment on April 1, 2023.
To the extent the Partnership makes an offer to purchase, and the offer is not fully accepted by the holders of the 2026 Secured Notes, the Partnership may use any remaining amount not accepted for any purpose not prohibited by the 2026 Secured Notes Indenture or the ABL Facility.
2025 Senior Notes. In February 2017, the Co-Issuers co-issued the 2025 Senior Notes. The Partnership pays 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 the Partnership’s existing and future senior obligations. The 2025 Senior Notes are effectively subordinated in right of payment to all of the Partnership’s secured indebtedness, to the extent of the collateral securing such indebtedness.
The Co-Issuers have the right to redeem all or part of the 2025 Senior Notes at a redemption price of 101.438% (with the redemption price declining ratably each year to 100.00% on April 15, 2023), plus accrued and unpaid interest, if any, to, but not including the redemption date.
As of March 31, 2023, the Partnership was in compliance with the financial covenants governing its 2025 Senior Notes.

________
(1) Excludes applicable unamortized debt issuance costs and debt discounts.
The carrying values on the balance sheets of the ABL Facility and Permian Transmission Term Loan represents their fair value due to their floating interest rates. The fair values of the 2026 Secured Notes and 2025 Senior Notes are based on an average of nonbinding broker quotes as of March 31, 2023 and December 31, 2022. The use of different market assumptions or valuation methodologies may have a material effect on their estimated fair value.
Deferred earn-out. As a result of the acquisition of Sterling DJ, the Partnership assumed a deferred earn-out liability, which is remeasured each reporting period. As of March 31, 2023 and December 31, 2022, the estimated fair value of the deferred earn-out liability was $5.4 million and $5.2 million, respectively, and was estimated using a discounted cash flow technique based on estimated future fresh water deliveries and appropriate discount rates. Given the unobservable nature of the inputs, the fair value measurement of the deferred earn-out is deemed to use Level 3 inputs. The deferred earn-out sits within Centennial Water Pipelines LLC, one of the Partnership’s unrestricted subsidiaries.
Interest Rate Swaps. In connection with the Permian Transmission Term Loan, formerly the Permian Transmission Credit Facility, the Partnership entered into amortizing interest rate swap agreements. As of March 31, 2023 and December 31, 2022, the outstanding notional amounts of interest rate swaps were $137.6 million and $139.8 million, respectively. These interest rate swaps manage exposure to variability in expected cash flows attributable to interest rate risk. Interest rate swaps convert a
16

Table of Contents
portion of the Partnership’s variable rate debt to fixed rate debt. The Partnership chooses counterparties for its derivative instruments that it believes are creditworthy at the time the transactions are entered into, and the Partnership actively monitors the creditworthiness where applicable. However, there can be no assurance that a counterparty will be able to meet its obligations to the Partnership. The Partnership presents its derivative positions on a gross basis and does not net the asset and liability positions.
As of March 31, 2023 and December 31, 2022, the Partnership’s interest rate swap agreements had a fair value of $12.8 million and $15.2 million, respectively, and are recorded within other noncurrent assets within the unaudited condensed consolidated balance sheets. The derivative instruments’ fair value are determined using level 2 inputs from the fair value hierarchy. For the three months ended March 31, 2023, the Company recorded a loss on interest rate swaps of $1.3 million.

Series A Preferred Units. As of March 31, 2023, the Partnership had 65,508 Series A Preferred Units outstanding and $24.1 million of accrued and unpaid distributions on its Series A Preferred Units.
Series A Preferred Unit Exchange Offers. In January 2022, the Partnership completed an offer to exchange its Series A Preferred Units for newly issued common units (the “2022 Preferred Exchange Offer”), whereby it issued 2,853,875 SMLP common units, net of units withheld for withholding taxes, in exchange for 77,939 Series A Preferred Units. As a result of the transaction, the Partnership recognized a deemed contribution of $20.9 million from the Series A Preferred Unit holders to the common unit holders.
Subsidiary Series A Preferred Units. The Partnership records its Subsidiary Series A Preferred Units at fair value upon issuance, net of issuance costs, and subsequently records an effective interest method accretion amount each reporting period to accrete the carrying value to a most probable redemption value that is based on a predetermined internal rate of return measure. If the Partnership elects to make payment-in-kind (“PIK”) distributions to holders of its Subsidiary Series A Preferred Units, these PIK distributions increase the liquidation preference on each Subsidiary Series A Preferred Unit. Net Income (Loss) attributable to our common units includes adjustments for PIK distributions and redemption accretion.
As of March 31, 2023, the Partnership had 93,039 Subsidiary Series A Preferred Units issued and outstanding.
If the Subsidiary Series A Preferred Units were redeemed on March 31, 2023, the redemption amount would be $121.2 million when considering the applicable multiple of invested capital metric and make-whole amount provisions contained in the Subsidiary Series A Preferred Unit agreement.
The following table shows the change in our Subsidiary Series A Preferred Unit balance from January 1, 2023 to March 31, 2023, net of $2.1 million and $2.2 million of unamortized issuance costs at March 31, 2023 and December 31, 2022, respectively:

Cash Distribution Policy. The Partnership suspended its cash distributions to holders of its common units, commencing with respect to the quarter ended March 31, 2020. Upon the resumption of distributions, the Partnership Agreement requires that it distribute all available cash, subject to reserves established by its General Partner, within 45 days after the end of each quarter to unitholders of record on the applicable record date. The amount of distributions paid under this policy is subject to fluctuations based on the amount of cash the Partnership generates from its business and the decision to make any distribution is determined by the General Partner, taking into consideration the terms of the Partnership Agreement. There were no distributions paid during the three months ended March 31, 2023 or during the twelve months ended December 31, 2022.

SMLP Long-Term Incentive Plan. The Partnership’s Long-Term Incentive Plan (“SMLP LTIP”) provides for equity awards to eligible officers, employees, consultants and directors of the Partnership, thereby linking the recipients’ compensation directly to SMLP’s performance. Significant items to note: 
For the three-month period ended March 31, 2023, the Partnership granted 212,893 time-based phantom units and associated distribution equivalent rights to employees in connection with the Partnership’s annual incentive compensation award cycle. These awards had a grant date fair value of $16.00 per common unit and vest ratably over a 3-year period.
For the three-month period ended March 31, 2023, the Partnership granted 110,478 performance-based phantom units and associated distribution equivalent rights to certain members of management in connection with the
18

Partnership’s annual incentive compensation award cycle. The grant date fair value of these awards total $2.2 million.
For the three-month period ended March 31, 2023, the Partnership issued 38,100 common units to the Partnership’s six independent directors in connection with their annual compensation plan. These awards had a grant date fair value of $16.00 per common unit and vested immediately.
As of March 31, 2023, approximately 0.5 million common units remained available for future issuance under the SMLP LTIP, which includes the impact of 0.7 million granted but unvested phantom units.
14. COMMITMENTS AND CONTINGENCIES
Environmental Matters. Although the Partnership believes that it is in material compliance with applicable environmental regulations, the risk of environmental remediation costs and liabilities are inherent in pipeline ownership and operation. Furthermore, the Partnership can provide no assurances that significant environmental remediation costs and liabilities will not be incurred in the future. The Partnership is currently not aware of any material contingent liabilities that exist with respect to environmental matters, except as noted below.
As of March 31, 2023, the Partnership has recognized (i) a current liability for remediation effort expenditures expected to be incurred within the next 12 months and (ii) a noncurrent liability for estimated remediation expenditures expected to be incurred subsequent to March 31, 2024. Each of these amounts represent the Partnership’s best estimate for costs expected to be incurred. Neither of these amounts have been discounted to their present value.
An update of the Partnership’s undiscounted accrued environmental remediation is as follows and is primarily related to the 2015 Blacktail Release and other environmental remediation activities, as detailed below.

In 2015, the Partnership learned of the rupture of a four-inch produced water gathering pipeline on the Meadowlark Midstream system near Williston, North Dakota (“2015 Blacktail Release”). On August 4, 2021, subsidiaries of the Partnership entered into the following agreements to resolve the U.S. federal and North Dakota state governments’ environmental claims with respect to the 2015 Blacktail Release: (i) a Consent Decree with the U.S. Department of Justice (“DOJ”), the U.S. Environmental Protection Agency (“EPA”), and the State of North Dakota (“Consent Decree”); (ii) a Plea Agreement with the United States (“Plea Agreement”); and (iii) a Consent Agreement with the North Dakota Industrial Commission (“Consent Agreement” together with the Consent Decree and Plea Agreement, the “Global Settlement”). As of March 31, 2023 and December 31, 2022, the accrued loss liability for the 2015 Blacktail Release was $28.3 million and are recorded within Other noncurrent liabilities and Accrued settlement payable within the unaudited condensed consolidated balance sheets.
Key terms of the Global Settlement included (i) payment of penalties and fines totaling $36.3 million, consisting of $1.25 million in natural resource damages payable to federal and state governments, a $25.0 million payable to the federal government over 5 years, and a $10.0 million payable to state governments over six years, with interest applied to unpaid amounts accruing at a fixed rate of 3.25%, and of which $6.7 million is expected to be paid within the next twelve months; (ii) continuation of remediation efforts at the site of the 2015 Blacktail Release; (iii) other injunctive relief including but not limited to control room management, environmental management system audit, training, and reporting; (iv) guilty pleas by Defendant subsidiary for (a) one charge of negligent discharge of a harmful quantity of oil and (b) one charge of knowing failure to immediately report a discharge of oil; and (v) organizational probation for a minimum period of three years from sentencing, including payment in full of certain components of the fines and penalty amounts. The agreements comprising the Global Settlement were subject to the approval of the U.S. District Court for the District of North Dakota (the “U.S. District Court”). The U.S. District Court entered an order making the civil components of the Global Settlement effective on September 28, 2021 and accepted the sentencing in the Plea Agreement on December 6, 2021, completing approval of the Global Settlement.
In conjunction with the criminal proceedings under the Plea Agreement, the U.S. District Court received two claims for restitution, including claims for diminution in property value and the cost of additional environmental testing. The prosecution notified the U.S District Court that the government declined to support the claims, citing “insufficient evidence to support the claims.” Defendant subsidiary of the Partnership has responded that restitution is not applicable in this matter because claimants did not provide any supporting evidence for their claims that showed any harm, and because the plea agreement in this matter does not permit restitution sought by the claimants. On August 4, 2022, the U.S. District Court denied the claims.

Table of Contents
Subsidiaries of the Partnership are also participating in two proceedings before the EPA as a result of the Plea Agreement becoming effective. Following the U.S. District Court’s entering judgment on Defendant subsidiary’s guilty plea to one count of negligent discharge of produced water in violation of the Clean Water Act, Defendant subsidiary was statutorily debarred by operation of law pursuant to 33 U.S.C. § 1368(a) to participate in federal awards performed at the “violating facility,” which EPA determined to be the Marmon subsystem of the produced water gathering system in North Dakota. The scope and effect of the debarment as defined do not materially affect our operations. Defendant has submitted a petition for reinstatement, which was denied by the EPA’s suspension and debarment office (“SDO”) on July 11, 2022. The SDO determined that the term of probation in the Plea Agreement was the appropriate period of time to demonstrate Defendant subsidiary’s change of corporate attitude, policies, practices, and procedures. The Partnership and certain subsidiaries have also received a show cause notice from the EPA requesting us to “show cause” why SDO should not issue a Notice of Proposed Debarment to the Defendant subsidiary and certain affiliates under 2 C.F.R. § 180.800(d), to which we have responded.
Legal Proceedings. The Partnership is involved in various litigation and administrative proceedings arising in the ordinary course of business. In the opinion of management, any liabilities that may result from these claims or those arising in the ordinary course of business would not individually or in the aggregate have a material adverse effect on the Partnership's financial position or results of operations.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
This Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) is intended to inform the reader about matters affecting the financial condition and results of operations of the Partnership and its subsidiaries for the periods since December 31, 2022. As a result, the following discussion should be read in conjunction with the unaudited condensed consolidated financial statements and notes thereto included in this report and the MD&A and the audited consolidated financial statements and related notes that are included in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2022 (the “2022 Annual Report”). Among other things, those financial statements and the related notes include more detailed information regarding the basis of presentation for the following information. This discussion contains forward-looking statements that constitute our plans, estimates and beliefs. These forward-looking statements involve numerous risks and uncertainties, including, but not limited to, those discussed in Forward-Looking Statements. Actual results may differ materially from those contained in any forward-looking statements.
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.
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 Rockies and Piceance segments, (ii) the sale of natural gas we retain from certain Barnett segment customers, (iii) the sale of condensate we retain from our gathering services in the Piceance segment and (iv) additional gathering fees that are tied to the performance of certain commodity price indexes which are then added to the fixed gathering rates.
We also have indirect exposure to changes in commodity prices such 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. Commodity prices have increased and remain at higher levels primarily due to recent production cuts by OPEC+ and Russia’s invasion of Ukraine which began in February 2022, which mitigates the risk of cancelled or delayed drilling and/or completion activities.

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 current Russia-Ukraine conflict and the international sanctions against Russia on commodity prices;
Natural gas, NGL and crude oil supply and demand dynamics;
Production from U.S. shale plays;
Capital markets availability and cost of capital; and
Inflation and shifts in operating costs.
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. For additional information, see the "Trends and Outlook" section of MD&A included in the 2022 Annual Report.
Strategic DJ Acquisitions. On December 1, 2022, we completed the 2022 DJ Acquisitions for total cash consideration of $305.0 million, subject to post-closing adjustments. As a result of the 2022 DJ Acquisitions, we acquired natural gas gathering and processing systems, a crude oil gathering system, freshwater rights, and a subsurface freshwater delivery system in the DJ Basin. The acquired assets of Outrigger DJ and Sterling DJ are located in Weld, Morgan, and Logan Counties, Colorado and Cheyenne County, Nebraska. In 2023, we will spend time and resources integrating the 2022 DJ Acquisitions into our existing DJ Basin assets and expect to attain capital and operating synergies in the future.
Cost structure optimization and portfolio management. The Partnership intends to improve its capital structure in the future by reducing its indebtedness with free cash flow, and when appropriate, it may pursue opportunistic transactions with the objective of increasing long term unitholder value. This may include opportunistic acquisitions (such as the 2022 DJ Acquisitions), divestitures (such as the disposition of the Lane G&P System and of Bison Midstream), re-allocation of capital to new or existing areas, and development of joint ventures involving our existing midstream assets or new investment opportunities. We believe that our internally generated cash flow, our ABL Facility, the Permian Term Loan Facility, and access to debt (such as the Additional 2026 Secured Notes) or equity will be adequate to finance our strategic initiatives. To attain our overall
23

Table of Contents
corporate strategic objectives, we may conduct an asset divestiture, or divestitures, at a transaction valuation that is less than the net book value of the divested asset.
Ongoing impact of the current Russia-Ukraine conflict and the international sanctions against Russia on commodity prices. Although the Partnership does not operate in Ukraine, Russia or other parts of Europe, there are certain impacts arising from Russia’s invasion of Ukraine that could have a potential effect on the Partnership, including, but not limited to, volatility in currencies and commodity prices, higher inflation, cost and supply chain pressures and availability and disruptions in banking systems and capital markets. As of the date of filing, there have been no material impacts on the Partnership.
Based on recently updated production forecasts and 2023 development plans from our customers, we currently expect that 2023 activity will be higher than 2022 and be at an activity level near our historical periods prior to COVID-19.
Impact of recent increases in interest rates. Increases in interest rates could adversely affect our future ability to obtain financing or materially increase the cost of existing and any additional financing. Since March 2022, the Federal Reserve has raised its target range for the federal funds rate ten times, to a current target range of 5.00-5.25%. The Federal Reserve may pause such rate hikes or increase its target range further. As of March 31, 2023, we had approximately $1.0 billion principal of fixed-rate debt, $317.0 million outstanding under our variable rate ABL Facility and $152.8 million outstanding under the variable rate Permian Transmission Term Loan (see Note 8 - Debt). As of March 31, 2023, we had $137.6 million of interest rate exposure hedged to offset the impact of changes in interest rates on our Permian Transmission Term Loan.
The Inflation Reduction Act of 2022 could accelerate the transition to a low carbon economy and will impose new costs on our operations. On August 16, 2022, the Inflation Reduction Act of 2022 (“IRA 2022”) was signed into law pursuant to the budget reconciliation process. The IRA 2022 contains hundreds of billions of dollars in incentives for the development of renewable energy, clean hydrogen, clean fuels, electric vehicles and supporting infrastructure and carbon capture and sequestration, among other provisions. These incentives could further accelerate the transition of the U.S. economy away from the use of fossil fuels towards lower- or zero-carbon emissions alternatives, which could decrease demand for the oil and gas and consequently materially and adversely affect our business and results of operations. We do not currently believe this legislation will have a material impact on our consolidated financial statements.
How We Evaluate Our Operations
We conduct and report our operations in the midstream energy industry through five reportable segments: Northeast, Rockies, Permian, Piceance and Barnett. 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. For additional information see Note 15 - Segment Information.
Our management uses a variety of financial and operational metrics to analyze our consolidated and segment performance. We view these metrics as important factors in evaluating our profitability. These metrics include:
throughput volume;
revenues;
operation and maintenance expenses;
capital expenditures; and
segment adjusted EBITDA.
We review these metrics on a regular basis for consistency and trend analysis. There have been no changes in the composition or characteristics of these metrics during the three months ended March 31, 2023.
Additional Information. For additional information, see the "Results of Operations" section herein and the notes to the unaudited condensed consolidated financial statements. For additional information on how these metrics help us manage our business, see the "How We Evaluate Our Operations" section of MD&A included in the 2022 Annual Report. For information on impending accounting changes that are expected to materially impact our financial results reported in future periods, see Note 2 – Summary of Significant Accounting Policies and Recently Issued Accounting Standards Applicable to the Partnership.

Volumes – Liquids. Crude oil and produced water throughput volumes at the Rockies segment increased for the three months ended March 31, 2023, compared to the three months ended March 31, 2022, primarily as a result of 53 new well connections that came online subsequent to March 31, 2022, offset by natural production declines and weather related downtime.
For additional information on volumes, see the "Segment Overview for the Three Months Ended March 31, 2023 and 2022" section herein.
Revenues. Total revenues increased $16.4 million during the three months ended March 31, 2023 compared to the prior year period, comprised of a $26.7 million increase in natural gas, NGLs and condensate sales, offset by a $6.6 million decrease in gathering services and related fees and a $3.7 million decrease in Other Revenue.
Gathering Services and Related Fees. Gathering services and related fees decreased $6.6 million compared to the three months ended March 31, 2022, primarily reflecting:
a $1.0 million decrease in the Piceance, primarily due to decreased volume throughput and the expiration of a customer’s minimum volume commitment;
a $1.9 million decrease in the Northeast, primarily due to decreased volume throughput;
a $2.5 million decrease in the Rockies, primarily due to the sale of Bison Midstream in September 2022.
Natural Gas, NGLs and Condensate Sales. Natural gas, NGLs and condensate revenues increased $26.7 million compared to the three months ended March 31, 2022, primarily reflecting:
a $33.7 million increase in revenues in the Rockies, primarily as a result of the 2022 DJ Acquisitions in December 2022; offset by
a $6.9 million decrease in revenues from the Permian as a result of the disposition of the Lane G&P System in June 2022.
Costs and Expenses. Total costs and expenses increased $13.4 million during the three months ended March 31, 2023 compared to the three months ended March 31, 2022.
Cost of Natural Gas and NGLs. Cost of natural gas and NGLs increased $8.6 million for the three months ended March 31, 2023 compared to the three months ended March 31, 2022, primarily driven by the acquisition of Sterling DJ in December 2022.
Operation and Maintenance. Operation and maintenance expense increased $6.9 million for the three months ended March 31, 2023 compared to the three months ended March 31, 2022 primarily as a result of the acquisitions of Sterling DJ and Outrigger DJ in December 2022, partially offset by the 2022 dispositions of the Lane G&P System in June 2022 and Bison Midstream in September 2022.
General and Administrative. General and administrative expense decreased $3.0 million for the three months ended March 31, 2023 compared to the three months ended March 31, 2022 primarily due to $2.4 million of employee severance costs incurred during the three months ended March 31, 2022.
Acquisition Integration Costs. Acquisition integration costs increased $1.5 million for the three months ended March 31, 2023, compared to the three months ended March 31, 2022 as a result of our December 2022 acquisitions of Sterling DJ and Outrigger DJ.
Depreciation and Amortization. Depreciation and amortization expense decreased $0.6 million for the three months ended March 31, 2023 compared to the three months ended March 31, 2022.
Interest Expense. The increase in interest expense for the three month period ended March 31, 2023, compared to three months ended March 31, 2022, primarily resulted from higher interest costs from the issuance of the additional principal amounts of the 2026 Secured Notes, borrowings on the Permian Transmission Term Loan, higher amortization expense of debt issuance costs

The increase in interest expense for the three months ended March 31, 2023, compared to three months ended March 31, 2022, primarily resulted from higher interest costs from the issuance of the additional principal amounts of the 2026 Secured Notes and borrowings on the Permian Transmission Term Loan, higher amortization expense of debt issuance costs and an increase of 50 basis points on the interest rate of our 2026 Secured Notes. Interest expense does not include the impact of gains or losses from our interest rate swaps entered into for the Permian Transmission Credit Facility.
Liquidity and Capital Resources
We rely primarily on internally generated cash flows as well as external financing sources, including our ABL Facility, and the issuance of debt, equity and preferred equity securities, and proceeds from potential asset divestitures to fund our capital expenditures. We believe that our ABL Facility and Permian Transmission Credit Facility, together with internally generated cash flows and access to debt or equity capital markets, will be adequate to finance our operations for the next twelve months without adversely impacting our liquidity.
We may enter into off-balance sheet arrangements and transactions that can give rise to material off-balance sheet obligations. As of March 31, 2023, our material off-balance sheet arrangements and transactions include (i) letters of credit outstanding against our ABL Facility aggregating to $4.3 million, and (ii) letters of credit outstanding against our Permian Transmission Credit Facility aggregating to $10.5 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.

Indebtedness Compliance as of March 31, 2023. As of March 31, 2023, we were in compliance with all covenants contained in the Senior Notes, the ABL Facility and the Permian Transmission Credit Facility. The ABL Facility requires that Summit Holdings not permit (i) the First Lien Net Leverage Ratio (as defined in the ABL Agreement) as of the last day of any fiscal quarter to be greater than 2.50:1.00, or (ii) the Interest Coverage Ratio (as defined in the ABL Agreement) as of the last day of any fiscal quarter to be less than 2.00:1.00. As of March 31, 2023, the First Lien Net Leverage Ratio and Interest Coverage Ratio was 1.24:1.00 and 2.37:1.00, respectively.
Credit Agreements and Financing Activities
ABL Facility. As of March 31, 2023, we had a $400.0 million revolving ABL Facility with a maturity date of May 1, 2026. As of March 31, 2023, the outstanding balance of the ABL Facility was $317.0 million and the available borrowing capacity totaled $78.7 million after giving effect to the issuance thereunder of $4.3 million of outstanding but undrawn irrevocable standby letters of credit.
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 March 31, 2023, the outstanding balance of the 2025 Senior Notes was $259.5 million. 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. As of March 31, 2023, the Co-Issuers could redeem all or part of the 2025 Senior Notes at a redemption price of 101.438% (and such redemption price has subsequently declined to 100.000% on April 15, 2023), plus accrued and unpaid interest, if any, to, but not including, the redemption date.
2026 Secured Notes. In November 2021, we issued $700.0 million of the 2026 Secured Notes, at a price of 98.5% of face value. Additionally, in November 2022, in connection with the 2022 DJ Acquisitions, we issued an additional $85.0 million of 2026 Secured Notes at a price of 99.26% of their face value. The Co-Issuers pay interest on the 2026 Secured Notes semi-annually on April 15 and October 15 of each year, and the 2026 Secured Notes are jointly and severally guaranteed, on a senior second-priority secured basis (subject to permitted liens), by us and each of our restricted subsidiaries that is an obligor under the ABL Facility, or under the 2025 Senior Notes on the issue date of the 2026 Secured Notes. As of March 31, 2023, the outstanding balance of the 2026 Secured Notes was $785.0 million.
The 2026 Secured Notes will mature on October 15, 2026; provided that, if the outstanding amount of the 2025 Senior Notes (or any refinancing indebtedness in respect thereof that has a final maturity on or prior to the date that is 91 days after the Initial Maturity Date (as defined in the 2026 Secured Notes Indenture)) is greater than or equal to $50.0 million on January 14, 2025, which is 91 days prior to the scheduled maturity date of the 2025 Senior Notes, then the 2026 Secured Notes will mature on January 14, 2025.
Starting in the first quarter of 2023 with respect to the fiscal year ended 2022, and continuing annually through the fiscal year ended 2025, we are required under the terms of the 2026 Secured Notes Indenture to, if it has Excess Cash Flow (as defined in the 2026 Secured Notes Indenture), and subject to its ability to make such an offer under the ABL Facility, offer to purchase an amount of the 2026 Secured Notes, at 100% of the principal amount plus accrued and unpaid interest, equal to 100% of the Excess Cash Flow generated in the prior year. Generally, if we do not offer to purchase designated annual amounts of its 2026 Secured Notes or reduce its first lien capacity under the 2026 Secured Notes Indenture per annum from 2023 through 2025, the interest rate on the 2026 Secured Notes is subject to certain rate escalations. Per the terms of the 2026 Secured Notes Indenture, the designated amounts are $50.0 million aggregate principal amount of the 2026 Secured Notes by April 1, 2023, otherwise the interest rate shall automatically increase by 50 basis points per annum; $100.0 million aggregate principal amount of the 2026 Secured Notes by April 1, 2024, otherwise the interest rate shall automatically increase by 100 basis points per annum (minus any amount previously increased); and $200.0 million aggregate principal amount of the 2026 Secured Notes by April 1, 2025, otherwise the interest rate shall automatically increase by 200 basis points per annum (minus any amount previously increased).
To the extent we make an offer to purchase, and the offer is not fully accepted by the holders of the 2026 Secured Notes, we may use any remaining amount not accepted for any purpose not prohibited by the 2026 Secured Notes Indenture, or the ABL Facility. Based on the amount of our Excess Cash Flow for the fiscal year ended 2022, we were not able to make offers to purchase in the designated amount for the fiscal year ended 2022; as a result, the interest rate on the 2026 Secured Notes increased 50 basis points to 9.00% effective with the first payment on April 1, 2023, resulting in increased annual interest expense of approximately $3.9 million.
We may in the future use a combination of cash, secured or unsecured borrowings and issuances of our common units or other securities and the proceeds from asset sales to retire or refinance our outstanding debt or Series A Preferred Units through privately negotiated transactions, open market repurchases, redemptions, exchange offers, tender offers or otherwise, but we are under no obligation to do so.

Capital Requirements
Overall.
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.
37

Table of Contents
For the three months ended March 31, 2023, cash paid for capital expenditures totaled $16.4 million which included $4.2 million of maintenance capital expenditures. For the three months ended March 31, 2023, there were no contributions to Ohio Gathering and we contributed $3.5 million to Double E.
We rely primarily on internally generated cash flows as well as external financing sources, including commercial bank borrowings and the issuance of debt, equity and preferred equity securities, and proceeds from potential asset divestitures to fund our capital expenditures. We believe that our internally generated cash flows, our ABL Facility and the Permian Transmission Credit Facility, and access to debt or equity capital markets, will be adequate to finance our operations for the next twelve months without adversely impacting our liquidity.
We estimate that our 2023 capital program will range from $45.0 million to $65.0 million, including between $10.0 million and $15.0 million of maintenance capital expenditures. We estimate that our 2023 investment in our Double E equity method investee will be approximately $5.0 million.
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 agreements with third parties; (ii) prevailing conditions and outlook in the natural gas, crude oil and NGLs and markets, and (iii) our ability to obtain financing from commercial banks, the capital markets, or other financing sources.
Excess Cash Flow Offers to Purchase.
Starting in the first quarter of 2023 with respect to the fiscal year ended 2022, and continuing annually through the fiscal year 2025, we are required under the terms of the 2026 Secured Notes Indenture to, if it has Excess Cash Flow (as defined in the 2026 Secured Notes Indenture), and subject to its ability to make such an offer under the ABL Facility, offer to purchase an amount of the 2026 Secured Notes, at 100% of the principal amount plus accrued and unpaid interest, equal to 100% of the Excess Cash Flow generated in the prior year. Excess Cash Flow is generally defined as consolidated cash flow minus the sum of capital expenditures and cash payments in respect of permitted investments and permitted restricted payments.
Generally, if we do not offer to purchase designated annual amounts of its 2026 Secured Notes or reduce its first lien capacity under the 2026 Secured Notes Indenture per annum from 2023 through 2025, the interest rate on the 2026 Secured Notes is subject to certain rate escalations. Per the terms of the 2026 Secured Notes Indenture, the designated amounts are to offer to purchase $50.0 million aggregate principal amount of the 2026 Secured Notes by April 1, 2023, otherwise the interest rate shall automatically increase by 50 basis points per annum; $100.0 million aggregate principal amount of the 2026 Secured Notes by April 1, 2024, otherwise the interest rate shall automatically increase by 100 basis points per annum (minus any amount previously increased); and $200.0 million aggregate principal amount of the 2026 Secured Notes by April 1, 2025, otherwise the interest rate shall automatically increase by 200 basis points per annum (minus any amount previously increased). Based on the amount of our Excess Cash Flow for the fiscal year ended 2022, we did not make offers to purchase the designated amount for the fiscal year ended 2022; and as a result, the interest rate on the 2026 Secured Notes increased 50 basis points to 9.00% effective with the first payment on April 1, 2023, resulting in increased annual interest expense of approximately $3.9 million. To the extent we makes an offer to purchase, and the offer is not fully accepted by the holders of the 2026 Secured Notes, we may use any remaining amount not accepted for any purpose not prohibited by the 2026 Secured Notes Indenture or the ABL Facility.
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 potential customer, may 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.

Summarized Financial Information
The supplemental summarized financial information below reflects SMLP's separate accounts, the combined accounts of Summit Holdings and Finance Corp. (together, the “Co-Issuers”) and its guarantor subsidiaries (the “Guarantor Subsidiaries” and together with the Co-Issuers, 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 Permian Holdco and Summit Permian Transmission, both of which 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.
On June 30, 2022, we completed the sale of all the equity interests in Summit Permian and Permian Finance to a third party. Additionally, on September 19, 2022, we completed the sale of Bison Midstream to a third party. In connection with these dispositions, the status of Bison Midstream, Summit Permian and Permian Finance as guarantor subsidiaries, was modified prior to the occurrence of each respective disposition.
On December 1, 2022, we completed the acquisition of Outrigger DJ for cash consideration of $165.0 million, subject to post-closing adjustments, and Sterling DJ for cash consideration of $140.0 million, subject to post-closing adjustments. In connection with the acquisitions, Summit DJ - O, LLC (formerly Outrigger DJ Midstream, LLC), Summit DJ - O Operating, LLC (formerly Outrigger DJ Operating, LLC), Summit DJ - S, LLC (formerly Sterling Energy Investments, LLC), Grasslands Energy Marketing, LLC and Centennial Water Pipelines, LLC became newly acquired entities. With the exception of Centennial Water Pipeline, LLC, all acquired entities guarantee our obligations under the 2025 Senior Notes and 2026 Secured Notes.
The summarized financial information below presents the activities and balances of Bison Midstream, Summit Permian and Summit Finance as guarantor subsidiaries for all summarized income statement periods and balance sheet dates presented in which they were owned by the Partnership. Bison Midstream, Summit Permian and Permian Finance were not included in the Partnership’s balance sheet as of December 31, 2022.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.
Interest Rate Risk
Our interest rate risk exposure, which is largely related to our indebtedness, has not changed materially since December 31, 2022. As of March 31, 2023, we had approximately $1.0 billion principal of fixed-rate debt, $317.0 million outstanding under our variable rate ABL Facility and $152.8 million outstanding under the variable rate Permian Transmission Term Loan (see Note 8 - Debt). As of March 31, 2023, we had $137.6 million of interest rate exposure hedged to offset the impact of changes in interest rates on our Permian Transmission Term Loan. While existing fixed-rate debt mitigates the downside impact of fluctuations in interest rates, future issuances of long-term debt could be impacted by increases in interest rates, which could result in higher overall interest costs. In addition, the borrowings under our ABL Facility, which have a variable interest rate, also expose us to the risk of increasing interest rates. For additional information, see the "Interest Rate Risk" section included in Item 7A. Quantitative and Qualitative Disclosures About Market Risk of the 2022 Annual Report and updates to our risk factors included herein.
Commodity Price Risk
We generate a majority of our revenues pursuant to primarily long-term and fee-based gathering agreements, many of which include MVCs and areas of mutual interest. Our direct commodity price exposure relates to (i) the sale of physical natural gas and/or NGLs purchased under percentage-of-proceeds and other processing arrangements with certain of our customers in the Rockies and Piceance segments, (ii) the sale of natural gas we retain from certain Barnett segment customers and (iii) the sale of condensate we retain from certain gathering services in the Piceance segment. Our gathering agreements with certain Barnett customers permit us to retain a certain quantity of natural gas that we sell to offset the power costs we incur to operate our electric-drive compression assets. We manage our direct exposure to natural gas and power prices through the use of forward power purchase contracts with wholesale power providers that require us to purchase a fixed quantity of power at a fixed heat rate based on prevailing natural gas prices on the Henry Hub Index. We sell retainage natural gas at prices that are based on the Atmos Zone 3 Index. By basing the power prices on a system and basin-relevant market, we are able to closely associate the relationship between the compression electricity expense and natural gas retainage sales. We do not enter into risk management contracts for speculative purposes. Our current commodity price risk exposure has not changed materially since December 31, 2022. For additional information, see the "Commodity Price Risk" section included in Item 7A. Quantitative and Qualitative Disclosures About Market Risk of the 2022 Annual Report.
Item 4. Controls and Procedures.
Under the direction of our General Partner's Chief Executive Officer and Chief Financial Officer, we evaluated our disclosure controls and procedures and internal control over financial reporting and concluded that (i) our disclosure controls and procedures were effective as of March 31, 2023 and (ii) no change in internal control over financial reporting occurred during the quarter ended March 31, 2023, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION
Item 1. Legal Proceedings.
Although we may, from time to time, be involved in litigation and claims arising out of our operations in the ordinary course of business, we are not currently a party to any significant legal or governmental proceedings, except as described below. In addition, we are not aware of any significant legal or governmental proceedings contemplated to be brought against us, under the various environmental protection statutes to which we are subject.
Fiberspar Corporation. On May 3, 2022, Fiberspar Corporation filed a petition in state court alleging over $5.0 million owed but not paid for orders of pipeline product from Fiberspar. The petition asserts causes of action for breach of contract and suit on sworn account. A civil action on the same claims had been filed by Fiberspar in 2016 but was dismissed without prejudice pursuant to a standstill and tolling agreement that expired in 2021. We filed an answer on September 6, 2022 denying Fiberspar’s claims and asserting counter claims. The case is pending in the District Court of Harris County, Texas. It is currently set for trial in July 2023, but the parties have filed a joint motion for a continuance seeking a trial date in or after October 2023. We are unable to predict the final outcome of this matter.
Global Settlement. On August 4, 2021, the Partnership and several of its subsidiaries entered into agreements to resolve government investigations into the previously disclosed 2015 Blacktail Release, from a pipeline owned and operated by Meadowlark Midstream, which at the time was a wholly owned subsidiary of Summit Investments, (together with Meadowlark Midstream, the “Companies”). The Companies entered into the following agreements to resolve the U.S. federal and North Dakota state governments’ environmental claims against the Companies with respect to the 2015 Blacktail Release: (i) a Consent Decree with (a) the DOJ, on behalf of the U.S. Environmental Protection
Agency and the U.S. Department of Interior, and (b) the State of North Dakota, on behalf of the North Dakota Department of Environmental Quality and the North Dakota Game and Fish Department, lodged with the U.S. District Court; (ii) a Plea Agreement with the United States, by and through the U.S. Attorney for the District of North Dakota, and the Environmental Crimes Section of the DOJ; and (iii) a Consent Agreement with the North Dakota Industrial Commission.
The Consent Decree provides for, among other requirements and subject to the conditions therein, (i) payment of total civil penalties and reimbursement of assessment costs of $21.25 million, with the federal portion of penalties payable over up to five years and the state portion of penalties payable over up to six years, with interest accruing at a fixed rate of 3.25%; (ii) continuation of remediation efforts at the site of the 2015 Blacktail Release; (iii) other injunctive relief including but not limited to control room management, an environmental management system audit, training, and reporting; and (iv) no admission of liability to the U.S. or North Dakota. The Consent Decree was entered by the U.S. District Court on September 28, 2021.
The Consent Agreement settles a complaint brought by the NDIC in an administrative action against the Companies for alleged violations of the North Dakota Administrative Code (“NDAC”) arising from the 2015 Blacktail Release on the following terms: (i) the Companies admit to three counts of violating the NDAC; (ii) the Companies agree to follow the terms and conditions of the Consent Decree, including payment of penalty and reimbursement amounts set forth in the Consent Decree; and (iii) specified conditions in the Consent Decree regarding operation and testing of certain existing produced water pipelines shall survive until those pipelines are properly abandoned.
Under the Plea Agreement, the Companies agreed to, among other requirements and subject to the conditions therein, (i) enter guilty pleas for one charge of negligent discharge of a harmful quantity of oil and one charge of knowing failure to immediately report a discharge of oil; (ii) sentencing that includes payment of a fine of $15.0 million plus mandatory special assessments over a period of up to five years with interest accruing at the federal statutory rate; (iii) organizational probation for a minimum period of three years from sentencing, which will include payment in full of certain components of the fines and penalty amounts; and (iv) compliance with the remedial measures in the Consent Decree.
On December 6, 2021, the U.S. District Court accepted the Plea Agreement. This settlement resulted in losses amounting to $36.3 million and will be paid over six years, of which we have paid $8.0 million as of March 31, 2023.
Verdad Resources. Verdad Resources LLC (“Verdad”) filed a complaint in Colorado state court for the district of Weld County against Sterling Energy Investments LLC (“Sterling”), Golden Resources, Inc., and Grasslands Energy Marketing LLC (“Grasslands”) on October 20, 2022, and amended on December 6, 2022 to exclude Golden Resources, Inc. as a defendant. In connection with the 2022 DJ Acquisitions, Sterling and Grasslands became subsidiaries of the Partnership. Verdad claims that Sterling did not have the right to assess marketing fees passed through from Grasslands’ purchase and resale of residue natural gas and natural gas liquids from Sterling. The relief requested by Verdad includes approximately $3.6 million in damages plus pre-judgment interest as well as declaratory relief and recovery of costs. We are unable to predict the final outcome of this matter.

Highpoint Operating Corporation. Sterling and Highpoint Operating Corporation (“Highpoint”) are parties to a gas gathering agreement (the “Highpoint Agreement”). Sterling sued Highpoint in Colorado state court for the district of Denver County on June 15, 2020, alleging that Highpoint breached the Highpoint Agreement and seeking damages. Highpoint asserted counterclaims alleging that Sterling breached the Highpoint Agreement. In October 2021, after a bench trial, the court found against Sterling and in favor of Highpoint’s counterclaims. The court awarded Highpoint $2.4 million in damages. In December 2021, Sterling posted an appeal bond and filed its Notice of Appeal. In February 2022, the Colorado Court of Appeals granted Sterling’s Motion to Stay Execution of Judgment. On March 7, 2023, Summit DJ-S and Highpoint entered into a Confidential Settlement and Release Agreement that fully resolved all claims between the parties. On March 27, 2023, Highpoint filed a Notice of Satisfaction of Merits Judgment and Costs Award and the matter is now closed.
Sage Natural Resources. In July 2022, the Partnership’s subsidiary DFW Midstream Services LLC filed a petition in the District Court of Dallas County, Texas seeking payment of almost $1.0 million in electric power costs for gathering services provided to Sage Natural Resources, LLC in 2021-2022. Sage has denied the amounts are owed and has filed counterclaims seeking damages and other relief for DFW’s alleged breaches of the gathering agreement. A non-jury trial is currently scheduled for February 2024, and we are unable to predict the final outcome of this matter.
