Organization And Business	1. ORGANIZATION AND BUSINESS Organization We are a publicly-traded limited partnership formed in 2005 focused on the acquisition, development, and ownership of infrastructure critical to the transition of energy supply to lower carbon sources. We own natural gas gathering systems, pipelines, and processing facilities in South Texas and continue to pursue energy transition infrastructure opportunities. Our common units are currently listed on the NYSE American under the symbol “SNMP.” On February 26, 2021, in connection with our management team’s focus on expanding our business strategy to focus on the ongoing energy transition in the industries in which we operate, we changed our name from Sanchez Midstream Partners to Evolve Transition Infrastructure LP and our general partner changed its name to Evolve Transition Infrastructure GP LLC.

Basis Of Presentation And Summary Of Significant Accounting Policies
Basis of Presentation and Significant Accounting Policies	2. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation Accounting policies used by us conform to accounting principles generally accepted in the United States of America (“GAAP”). The accompanying financial statements include the accounts of us and our wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. These unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures, normally included in annual financial statements prepared in accordance with GAAP, have been condensed or omitted pursuant to those rules and regulations. We believe that the disclosures made are adequate to make the information presented not misleading. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary to fairly state the financial position, results of operations and cash flows with respect to the interim condensed consolidated financial statements have been included. The results of operations for the interim periods are not necessarily indicative of the results for the entire year. These unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2021, which was filed with the SEC on March 30, 2022. Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”), which are adopted by us as of the specified effective date. Unless otherwise discussed, management believes that the impact of recently issued standards, which are not effective, will not have a material impact on our consolidated financial statements upon adoption. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This ASU modifies the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in more timely recognition of losses. Additionally, in November 2019, the FASB issued ASU 2019-10, “Financial Instruments – Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates,” which changed the effective date for certain issuers to annual and interim periods in fiscal years beginning after December 15, 2022, and earlier adoption is permitted. We are currently in the process of evaluating the impact of adoption of this guidance on our condensed consolidated financial statements. Other accounting standards that have been issued by the FASB or other standards-setting bodies are not expected to have a material impact on the Partnership’s financial position, results of operations and cash flows. Use of Estimates The condensed consolidated financial statements are prepared in conformity with GAAP, which requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities and reported amounts of revenues and expenses. The estimates that are particularly significant to our financial statements include estimates of our reserves of natural gas, NGLs and oil; future cash flows from oil and natural gas properties; depreciation, depletion and amortization; asset retirement obligations; certain revenues and operating expenses; fair values of derivatives; and fair values of assets and liabilities. As fair value is a market-based measurement, it is determined based on the assumptions that market participants would use. These estimates and assumptions are based on management’s best judgment using the data available. Management evaluates its estimates and assumptions on an on-going basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. Such estimates and assumptions are adjusted when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ from the estimates. Any changes in estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.

Discontinued Operations	3. DISCONTINUED OPERATIONS Kodiak Sale On March 11, 2022, we entered into a purchase and sale agreement with Kodiak Gas Services, LLC (“Kodiak”), pursuant to which Evolve sold to Kodiak natural gas compression equipment for a purchase price of $250 thousand. We recorded a loss of approximately $2.2 million on the sale. Palmetto Divestiture On April 30, 2021, but effective March 1, 2021 (the “Palmetto Effective Time”), SEP Holdings IV, LLC (“SEP IV”), a wholly-owned subsidiary of the Partnership entered into a purchase agreement (the “Palmetto PSA”) with Westhoff Palmetto LP (“Palmetto Buyer”), pursuant to which SEP IV sold to Palmetto Buyer specified wellbores and other associated assets located in Gonzales and Dewitt Counties, Texas (the “Palmetto Assets”) for a base purchase price of approximately $11.5 million, including the impact of final post-closing adjustments (the “Palmetto Divestiture”). Pursuant to the Palmetto PSA, other than a limited amount of retained obligations, Palmetto Buyer agreed to assume all obligations relating to the Palmetto Assets that arose on or after the Palmetto Effective Time. The Palmetto PSA contains customary representations and warranties by SEP IV and Palmetto Buyer, and SEP IV and Palmetto Buyer have agreed to customary indemnities relating to breaches of representations, warranties and covenants and the payment of assumed and excluded obligations. The Palmetto Divestiture closed simultaneously with the execution of the Palmetto PSA and we recorded a gain of approximately $0.3 million on the sale. Maverick Divestitures On April 30, 2021, but effective March 1, 2021 (the “Maverick Effective Time”), SEP IV entered into a purchase agreement (the “Maverick PSA”) with Bayshore Energy TX LLC (“Maverick Buyer”), pursuant to which SEP IV sold to Maverick Buyer specified wellbores and other associated assets located in Zavala County, Texas (the “Maverick 1 Assets”) for a base purchase price of approximately $2.8 million, prior to post-closing adjustments (the “Maverick 1 Divestiture”). Pursuant to the Maverick PSA, other than a limited amount of retained obligations, Maverick Buyer agreed to assume all obligations relating to the Maverick 1 Assets that arose on or after the Maverick Effective Time. The Maverick PSA contains customary representations and warranties by SEP IV and Maverick Buyer, and SEP IV and Maverick Buyer agreed to customary indemnities relating to breaches of representations, warranties and covenants and the payment of assumed and excluded obligations. The Maverick 1 Divestiture closed simultaneously with the execution of the Maverick PSA. Also on April 30, 2021, SEP IV entered into a letter agreement with Maverick Buyer (the “Maverick Letter Agreement”) pursuant to which SEP IV agreed to sell additional other specified wellbores and other associated assets located in Zavala and Dimmit Counties, Texas (the “Maverick 2 Assets”) for a base purchase price of approximately $1.4 million, prior to post-closing adjustments (the “Maverick 2 Divestiture”). The closing of the Maverick 2 Divestiture was conditioned upon SEP IV obtaining certain consents and complying with other preferential rights related to the Maverick 2 Assets. Following the entrance into the Maverick Letter Agreement, SEP IV complied with the preferential rights and obtained multiple consents related to the Maverick 2 Assets. SEP IV did not obtain one of the required consents and, as a result, the Maverick 2 Assets subject to such consent were removed from the Maverick 2 Assets included in the Maverick 2 Divestiture (the “Updated Maverick 2 Assets”) and the base purchase price was adjusted downward by approximately $31,000. On May 14, 2021, but effective as of the Maverick Effective Time, SEP IV and Maverick Buyer entered into a purchase agreement (the “Maverick 2 PSA”) pursuant to which SEP IV sold to Maverick Buyer the Updated Maverick 2 Assets. Pursuant to the Maverick 2 PSA, other than a limited amount of retained obligations, Maverick Buyer agreed to assume all obligations and liabilities related to the Updated Maverick 2 Assets that arose on or after the Maverick Effective Time. The Maverick 2 PSA contains customary representations and warranties by SEP IV and Maverick Buyer, and SEP IV and Maverick Buyer agreed to customary indemnities relating to breaches of representations, warranties and covenants and the payment of assumed and excluded obligations. The Maverick 2 Divestiture closed simultaneously with the execution of the Maverick 2 PSA. On August 13, 2021, but effect as of the Maverick Effective Time, SEP IV and Maverick Buyer entered into a Purchase Agreement (the “Maverick 3 PSA”) pursuant to which SEP IV sold to Maverick Buyer specified wellbores and other associated assets located in Zavala County, Texas, including the remaining Maverick 2 Assets excluded from the original closing of the Maverick 2 Divestiture (the “Maverick 3 Assets”) for a base purchase price of approximately $31,000, prior to post-closing adjustments (the “Maverick 3 Divestiture,” and together with the Maverick 1 Divestiture and the Maverick 2 Divestiture, the “Maverick Divestitures”). Pursuant to the Maverick 3 PSA, other than a limited amount of retained obligations, Maverick Buyer agreed to assume all obligations and liabilities related to the Maverick 3 Assets that arose on or after the Maverick Effective Time. The Maverick 3 PSA contains customary representations and warranties by SEP IV and Maverick Buyer, and SEP IV and Maverick Buyer agreed to customary indemnities relating to breaches of representations, warranties and covenants and the payment of assumed and excluded obligations. The Maverick 3 Divestiture closed simultaneously with the execution of the Maverick 3 PSA. We recorded a net loss of approximately $0.3 million related to the Maverick Divestitures. Information related to the upstream oil and natural gas assets sold have been reflected in the condensed consolidated financial statements as discontinued operations.

Revenue Recognition

Revenue Recognition
Revenue Recognition	4. REVENUE RECOGNITION Revenue from Contracts with Customers The unit of account in ASC 606 is a performance obligation, which is a promise in a contract to transfer to a customer either a distinct good or service (or bundle of goods or services) or a series of distinct goods or services provided over a period of time. ASC 606 requires that a contract’s transaction price, which is the amount of consideration to which an entity expects to be entitled in exchange for transferring promised goods or services to a customer, is to be allocated to each performance obligation in the contract based on relative standalone selling prices and recognized as revenue when (point in time) or as (over time) the performance obligation is satisfied. Disaggregation of Revenue The Gathering Agreement is classified as an operating lease and is accounted for under ASC 842, “Leases” and is reported as gathering and transportation lease revenues in our condensed consolidated statements of operations. During the three months ended March 31, 2022 and 2021, we recognized revenue of approximately $15.1 million and $9.3 million, respectively, under ASC 842. Mesquite accounted for 100% and 79% of total revenue for the three months ended March 31, 2022, and 2021, respectively. We are highly dependent upon Mesquite as our most significant customer. During the three months ended March 31, 2022 and 2021, we did not record any revenue under ASC 606. We disaggregate revenue based on revenue and product type. In selecting the disaggregation categories, we considered a number of factors, including disclosures presented outside the financial statements, such as in our earnings release and investor presentations, information reviewed internally for evaluating performance, and other factors used by the Partnership or the users of its financial statements to evaluate performance or allocate resources. We have concluded that disaggregating revenue by revenue and product type appropriately depicts how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. We account for income from our unconsolidated equity method investments as earnings from equity investments in our condensed consolidated statements of operations. Earnings from these equity method investments are further discussed in Note 11 “Investments.” Contract Balances At March 31, 2022 and December 31, 2021, our accounts receivable from contracts with customers were approximately $27.8 million and $19.1 million, respectively, under ASC 842. The gathering and transportation lease revenues utilized to determine net loss for the three months ended March 31, 2022 do not net out the approximately $9.6 million of such revenues that have not been collected from Mesquite. As previously disclosed, on June 24, 2021, we increased the tariff rate for interruptible throughput volumes from Eastern Catarina. Despite the increase, Mesquite continues to short-pay invoices and is currently paying the fees being charged for throughput volumes from Western Catarina for all throughput volumes from Eastern Catarina. At March 31, 2022 and December 31, 2021, the amount Mesquite continues to short-pay invoices is approximately $25.8 million and $16.2 million, respectively. As previously disclosed, on August 30, 2021, Catarina Midstream, LLC, our wholly owned subsidiary (“Catarina Midstream”) initiated a non-administered arbitration against SN Catarina, LLC pursuant to the International Institute for Conflict Prevention & Resolution Non-Administered Arbitration Rules (the “Catarina Arbitration”). The Catarina Arbitration seeks to bring commercial resolution to the tariff rate on Eastern Catarina and all disputed amounts are being held in accounts receivable during the pendency of the Catarina Arbitration. We continue to evaluate the collectability of the amounts being held in accounts receivable. Additionally, we are also involved in adversary proceeding 21-03931 (MI), which Mesquite and SN Catarina, LLC initiated against us and Catarina Midstream in the Bankruptcy Court (the “Mesquite Adversary”). There can be no guarantee that we are able to reach any commercial resolution and our failure to do so could adversely affect our business, financial condition, cash flows and results of operations. Under our sales contracts, we invoice customers after our performance obligations have been satisfied, at which point payment is unconditional. Accordingly, our contracts do not give rise to contract assets or liabilities under ASC 606. At March 31, 2022 and December 31, 2021, our accounts receivables from contracts with customers was zero.

Fair Value Measurements

Fair Value Measurements
Fair Value Measurements	5. FAIR VALUE MEASUREMENTS Measurements of fair value of derivative instruments are classified according to the fair value hierarchy, which prioritizes the inputs to the valuation techniques used to measure fair value. Fair value is the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are classified and disclosed in one of the following categories: Level 1: Level 2: Level 3: Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. Management's assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of the fair value of assets and liabilities and their placement within the fair value hierarchy levels. The following table summarizes the fair value of our assets and liabilities that were accounted for at fair value on a recurring basis as of March 31, 2022 (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements at March 31, 2022 ​ ​ Active Markets for ​ Observable ​ ​ ​ ​ ​ ​ ​ Identical Assets ​ Inputs ​ Unobservable Inputs ​ ​ ​ (Level 1) (Level 2) (Level 3) Fair Value Fair value of warrants ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nuvve Holding Warrants ​ $ — ​ $ — ​ $ — ​ $ — Other liabilities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Stonepeak Warrant ​ ​ — ​ ​ (7,760) ​ ​ — ​ ​ (7,760) Total ​ $ — ​ $ (7,760) ​ $ — ​ $ (7,760) The following table summarizes the fair value of our assets and liabilities that were accounted for at fair value on a recurring basis as of December 31, 2021(in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements at December 31, 2021 ​ ​ Active Markets for ​ Observable ​ ​ ​ ​ ​ ​ ​ Identical Assets ​ Inputs ​ Unobservable Inputs ​ ​ ​ (Level 1) (Level 2) (Level 3) Fair Value Fair value of warrants ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nuvve Holding Warrants ​ $ — ​ $ 664 ​ $ — ​ $ 664 Other liabilities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Stonepeak Warrant ​ ​ — ​ ​ (7,197) ​ ​ — ​ ​ (7,197) Total ​ $ — ​ $ (6,533) ​ $ — ​ $ (6,533) ​ As of March 31, 2022 and December 31, 2021, the estimated fair value of cash and cash equivalents, accounts receivable, other current assets and current liabilities approximated their carrying value due to their short-term nature. Fair Value on a Non-Recurring Basis The Partnership follows the provisions of Topic 820-10, “Fair Value Measurement,” for nonfinancial assets and liabilities measured at fair value on a non-recurring basis. The fair value measurements of assets acquired and liabilities assumed are based on inputs that are not observable in the market and therefore represent Level 3 inputs under the fair value hierarchy. We periodically review oil and natural gas properties and related equipment for impairment when facts and circumstances indicate that their carrying values may not be recoverable. A reconciliation of the beginning and ending balances of the Partnership’s asset retirement obligations is presented in Note 9 “Asset Retirement Obligation.” Fair Value of Financial Instruments The estimated fair value amounts of financial instruments have been determined using available market information and valuation methodologies described below. We prioritize the use of the highest level inputs available in determining fair value such that fair value measurements are determined using the highest and best use as determined by market participants and the assumptions that they would use in determining fair value.

Debt

Debt	3 Months Ended

Debt
Debt	7. DEBT Credit Agreement We have entered into a credit facility with Royal Bank of Canada, as administrative agent and collateral agent, and the lenders party thereto, as amended through the date of the Twelfth Amendment to Third Amended and Restated Credit Agreement, dated as of August 20, 2021 (the “Credit Agreement”). The Credit Agreement provides a quarterly amortizing term loan of $65.0 million (the “Term Loan”) and a maximum revolving credit amount of $5.0 million (the “Revolving Loan”). The Credit Agreement matures on September 30, 2023. Borrowings under the Credit Agreement are secured by various mortgages of midstream properties that we own as well as various security and pledge agreements among us, certain of our subsidiaries and the administrative agent. Borrowings under the Credit Agreement are available for limited direct investment in midstream properties, acquisitions, and working capital and general business purposes. The Credit Agreement has a sub-limit of up to $2.5 million which may be used for the issuance of letters of credit. As of March 31, 2022, we had approximately $47.7 million of debt outstanding, consisting of approximately $46.2 million under the Term Loan and approximately $1.5 million under the Revolving Loan. We are required to make mandatory amortizing payments of outstanding principal on the Term Loan of (i) $3.0 million per fiscal quarter commencing with the quarter ending December 31, 2021, and (ii) $2.0 million per fiscal quarter commencing with the quarter ending March 31, 2023. As of March 31, 2022, we have met our mandatory amortizing payments of outstanding principal on the Term Loan through June 30, 2022. The maximum revolving credit amount is $5.0 million, leaving us with approximately $3.5 million in unused borrowing capacity. There were no letters of credit outstanding under our Credit Agreement as of March 31, 2022. At our election, interest for borrowings under the Credit Agreement are determined by reference to (i) the London Interbank Offered Rate (“LIBOR”) plus an applicable margin between 2.75% and 3.50% per annum based on net debt to EBITDA or (ii) a domestic bank rate (“ABR”) plus an applicable margin between 1.75% and 2.50% per annum based on net debt to EBITDA plus (iii) a commitment fee of 0.50% per annum based on the unutilized portion of the Revolving Loan. Interest on the borrowings for ABR loans and the commitment fee are generally payable quarterly. Interest on the borrowings for LIBOR loans are generally payable at the applicable maturity date. The Credit Agreement contains various covenants that limit, among other things, our ability to incur certain indebtedness, grant certain liens, merge or consolidate, sell all or substantially all of our assets, make certain loans, acquisitions, capital expenditures and investments, and pay distributions to unitholders. In addition, we are required to maintain the following financial covenants: ● current assets to current liabilities, excluding any current maturities of debt, of at least 1.0 to 1.0 at all times; and ● senior secured net debt to consolidated adjusted EBITDA for the last twelve months, as of the last day of any fiscal quarter, of not greater than 3.25 to 1.00. The Credit Agreement also includes customary events of default, including events of default relating to non-payment of principal, interest or fees, inaccuracy of representations and warranties when made or when deemed made, violation of covenants, cross-defaults, bankruptcy and insolvency events, certain unsatisfied judgments, loan documents not being valid and a change in control. A change in control is generally defined as the occurrence of one of the following events: (i) our existing general partner ceases to be our sole general partner or (ii) certain specified persons shall cease to own more than 50% of the equity interests of our general partner or shall cease to control our general partner. If an event of default occurs, the lenders will be able to accelerate the maturity of the Credit Agreement and exercise other rights and remedies. At March 31, 2022, we were in compliance with the financial covenants contained in the Credit Agreement. We monitor compliance on an ongoing basis. If we are unable to remain in compliance with the financial covenants contained in our Credit Agreement or maintain the required ratios discussed above, the lenders could call an event of default and accelerate the outstanding debt under the terms of the Credit Agreement, such that our outstanding debt could become then due and payable. We may request waivers of compliance from the violated financial covenants from the lenders, but there is no assurance that such waivers would be granted. We are required to make mandatory amortizing payments of the outstanding principal on the Term Loan and we expect these quarterly amortizing payments will be made from our operating cash flows and other capital resources. However, there can be no assurance that operations and other capital resources will provide cash in sufficient amounts to make these mandatory amortizing payments. Debt Issuance Costs As of March 31, 2022 and December 31, 2021, our unamortized debt issuance costs were approximately $0.7 million and $0.6 million, respectively. These costs are amortized to interest expense in our consolidated statements of operations over the life of our Credit Agreement. Amortization of debt issuance costs recorded during the three months ended March 31, 2022 and 2021 was approximately $0.1 million and $0.2 million, respectively.

Asset Retirement Obligation
Asset Retirement Obligation	9. ASSET RETIREMENT OBLIGATION We recognize the fair value of a liability for an asset retirement obligation (“ARO”) in the period in which it is incurred if a reasonable estimate of fair value can be made. Each period, we accrete the ARO to its then present value. The associated asset retirement cost (“ARC”) is capitalized as part of the carrying amount of our oil and natural gas properties, equipment and facilities or gathering and transportation assets. Subsequently, the ARC is depreciated using the units-of-production method for production assets and the straight-line method for midstream assets. The AROs recorded by us relate to the plugging and abandonment of oil and natural gas wells and decommissioning of oil and natural gas gathering and other facilities. Inherent in the fair value calculation of AROs are numerous assumptions and judgments including the ultimate settlement amounts, inflation factors, credit adjusted discount rates, timing of settlement and changes in the legal, regulatory, environmental and political environments. To the extent future revisions to these assumptions result in adjustments to the recorded fair value of the existing ARO, a corresponding adjustment is made to the ARC capitalized as part of gathering and transportation assets. The following table is a reconciliation of changes in ARO for the three months ended March 31, 2022 and the year ended December 31, 2021 (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Year Ended ​ ​ March 31, 2022 ​ December 31, 2021 Asset retirement obligation, beginning balance ​ $ 4,700 ​ $ 4,313 Accretion expense ​ 102 ​ 387 Asset retirement obligation, ending balance ​ $ 4,802 ​ $ 4,700 ​ Additional AROs increase the liability associated with new oil and natural gas wells and other facilities as these obligations are incurred. Abandonments of oil and natural gas wells and other facilities reduce the liability for AROs. During the three months ended March 31, 2022 and the year ended December 31, 2021, there were no significant expenditures for abandonments and there were no assets legally restricted for purposes of settling existing AROs. During the year ended December 31, 2021, obligations were relieved as part of the Palmetto Divestiture and the Maverick Divestitures.

Intangible Assets	10. INTANGIBLE ASSETS Intangible assets are comprised of customer and marketing contracts. The intangible assets balance as of March 31, 2022, is related to the Gathering Agreement with Mesquite that was entered into as part of the acquisition of the Western Catarina gathering system. The Western Catarina gathering system (“Western Catarina Midstream”) is located on the western portion of Mesquite’s acreage position in Dimmit, La Salle and Webb counties, Texas (the western portion of such acreage, “Western Catarina”). Pursuant to the 15 -year agreement, Mesquite tenders all of its crude oil, natural gas and other hydrocarbon-based product volumes produced in the Western Catarina of the Eagle Ford Shale in Texas for processing and transportation through Western Catarina Midstream, with a right to tender additional volumes outside of the dedicated acreage. These intangible assets are being amortized using the straight-line method over the 15 -year life of the agreement. Amortization expense for each of the three months ended March 31, 2022 and 2021 was approximately $3.4 million. These costs are amortized to depreciation, depletion, and amortization expense in our condensed consolidated statements of operations. The following table is a reconciliation of changes in intangible assets (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, ​ December 31, ​ ​ 2022 ​ 2021 Beginning balance $ 118,329 $ 131,786 Amortization ​ ​ (3,365) ​ ​ (13,457) Ending balance $ 114,964 $ 118,329 ​

Investments	11. INVESTMENTS In July 2016, we completed a transaction pursuant to which we acquired from Mesquite a 50% interest in Carnero Gathering, LLC (“Carnero Gathering”), a joint venture that was 50% owned and operated by Targa Resources Corp. (NYSE: TRGP) (“Targa”), for an initial payment of approximately $37.0 million and the assumption of remaining capital commitments to Carnero Gathering, estimated at approximately $7.4 million as of the acquisition date (the “Carnero Gathering Transaction”). The fair value of the intangible asset for the contractual customer relationship related to Carnero Gathering was valued at approximately $13.0 million. This amount is being amortized over a contract term of 15 years and decreases earnings from equity investments in our condensed consolidated statements of operations. As part of the Carnero Gathering Transaction, we are required to pay Mesquite an earnout based on natural gas received above a threshold volume and tariff at designated delivery points from Mesquite and other producers. See Note 5 “Fair Value Measurements” for further discussion of the earnout derivative. In November 2016, we completed a transaction pursuant to which we acquired from Mesquite a 50% interest in Carnero Processing, LLC (“Carnero Processing”), a joint venture that was 50% owned and operated by Targa, for aggregate cash consideration of approximately $55.5 million and the assumption of remaining capital contribution commitments to Carnero Processing, estimated at approximately $24.5 million as of the date of acquisition. In May 2018, we executed a series of agreements with Targa and other parties pursuant to which, among other things: (1) the parties merged their respective 50% interests in Carnero Gathering and Carnero Processing (the “Carnero JV Transaction”) to form an expanded 50 / 50 joint venture in South Texas, within Carnero G&P, LLC (the “Carnero JV”), (2) Targa contributed 100% of the equity interest in the Silver Oak II Gas Processing Plant (“Silver Oak II”), located in Bee County, Texas, to the Carnero JV, which expands the processing capacity of the Carnero JV from 260 MMcf/d to 460 MMcf/d, (3) Targa contributed certain capacity in the 45 miles of high pressure natural gas gathering pipelines owned by Carnero Gathering that connect Western Catarina Midstream to nearby pipelines and the Raptor Gas Processing Facility (the “Carnero Gathering Line”) to the Carnero JV resulting in the Carnero JV owning all of the capacity in the Carnero Gathering Line, which has a design limit (without compression) of 400 MMcf/d, (4) the Carnero JV received a new dedication from Mesquite and its working interest partners of over 315,000 acres located in the Western Eagle Ford on Mesquite’s acreage in Dimmit, Webb, La Salle, Zavala and Maverick counties, Texas (such acreage is collectively referred to as Mesquite’s “Comanche Asset”) pursuant to a new long-term firm gas gathering and processing agreement. The agreement with Mesquite, which was approved by all of the unaffiliated Comanche Asset working interest partners, establishes commercial terms for the gathering of gas on the Carnero Gathering Line and processing at the Raptor Gas Processing Facility and Silver Oak II. Prior to execution of the agreement, volumes from the Comanche Asset were gathered and processed on an interruptible basis, with the processing capabilities of the Carnero JV limited by the capacity of the Raptor Gas Processing Facility. As a result of the Carnero JV Transaction, we now record our share of earnings and losses from the Carnero JV using the Hypothetical Liquidation at Book Value (“HLBV”) method of accounting. HLBV is a balance-sheet approach that calculates the amount we would have received if the Carnero JV were liquidated at book value at the end of each measurement period. The change in our allocated amount during the period is recognized in our condensed consolidated statements of operations. In the event of liquidation of the Carnero JV, available proceeds are first distributed to any priority return and unpaid capital associated with Silver Oak II, and then to members in accordance with their capital accounts. As of March 31, 2022, the Partnership had paid approximately $124.4 million for its investment in the Carnero JV related to the initial payments and contributed capital. The Partnership has accounted for this investment using the equity method. Targa is the operator of the Carnero JV and has significant influence with respect to the normal day-to-day capital and operating decisions. We have included the investment balance in the equity investments caption on the condensed consolidated balance sheets. For the three months ended March 31, 2022, the Partnership recorded earnings in equity investments from the Carnero JV of approximately $3.7 million, which was offset by approximately $0.3 million related to the amortization of the contractual customer intangible asset. We have included these equity method earnings in the earnings from equity investments line within the condensed consolidated statements of operations. Cash distributions of approximately $1.3 million were received during the three months ended March 31, 2022. As of December 31, 2021, an impairment of approximately $173.2 million was recorded at the JV level with approximately $55.0 million allocated to our net loss based on the Partnership’s proportionate share of aggregate capital contributions. At March 31, 2022, the carrying value of our investment in the Carnero JV was approximately $22.3 million. Summarized financial information of unconsolidated entities is as follows (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ March 31, ​ ​ 2022 2021 Sales $ 34,772 $ 22,829 Total expenses ​ ​ 28,028 ​ ​ 19,578 Net income ​ $ 6,744 ​ $ 3,251 ​

Common Unit Issuances We entered into a letter agreement with SP Holdings providing that during the period beginning with the fiscal quarter ended September 30, 2019 and continuing until the end of the fiscal quarter after the fiscal quarter in which we redeem all of our issued and outstanding Class C Preferred Units, SP Holdings agrees to delay receipt of its fees, not including reimbursement of costs, as a result, we have not issued any common units to SP Holdings in connection with providing services under the Shared Services Agreement for any quarter following the quarter ended June 30, 2019. As of March 31, 2022, the number of units to be issued under the Shared Services Agreement is 15,993,892. Class C Preferred Units On August 2, 2019, Stonepeak exchanged all of their current equity ownership for newly issued Class C Preferred Units and the Stonepeak Warrant in a private placement transaction (the “Exchange”). The holders of the Class C Preferred Units receive a quarterly distribution of 14.0% per annum payable in cash. To the extent that Available Cash (as defined in our partnership agreement) is insufficient to pay the distribution in cash, all or a portion of the distribution may be paid in Class C Preferred PIK Units (as defined in our partnership agreement). Distributions are to be paid on or about the last day of each of February, May, August and November following the end of each quarter and are charged to interest expense in our condensed consolidated statements of operations. Beginning January 1, 2022, Adjusted Available Cash (as defined in our partnership agreement) will be distributed to holders of the Class C Preferred Units to redeem a number of Class C Preferred Units to be determined based on the amount of Adjusted Available Cash. The Class C Preferred Units are accounted for as a current liability on our condensed consolidated balance sheet consisting of the following (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ March 31, ​ December 31, ​ ​ 2022 ​ 2021 Class C Preferred Units, beginning balance ​ $ 397,387 ​ $ 345,205 Accretion of discount ​ ​ — ​ ​ 52,182 Class C Preferred Units, ending balance ​ $ 397,387 ​ $ 397,387 On November 16, 2020, the Partnership and Stonepeak entered into the Stonepeak Letter Agreement wherein the parties agreed that the distribution on the Class C Preferred Units for the three months ended September 30, 2020 would be paid in common units instead of Class C Preferred PIK Units, cash or a combination thereof. The Stonepeak Letter Agreement also provides that Stonepeak will be able to elect to receive distributions on the Class C Preferred Units in common units for any quarter following the third quarter of 2020 by providing written notice to the Partnership no later than the last day of the calendar month following the end of such quarter. The table below reflects distributions on Class C Preferred Units which were elected to be paid in common units related to the periods indicated. ​ ​ ​ ​ ​ ​ ​ Class C Preferred Date of Three Months Ended Distribution of Common Units Distribution September 30, 2020 ​ ​ 22,274,869 ​ February 1, 2021 December 31, 2020 ​ ​ 12,445,491 ​ February 25, 2021 March 31, 2021 ​ ​ 13,763,249 ​ May 20, 2021 June 30, 2021 ​ ​ 8,012,850 ​ August 20, 2021 September 30, 2021 ​ ​ 10,832,186 ​ November 22, 2021 December 31, 2021 ​ ​ 24,502,356 ​ February 22, 2022 Stonepeak Warrant On August 2, 2019 , in connection with the Exchange, the Partnership issued to Stonepeak the Stonepeak Warrant, which entitles the holder to receive junior securities representing ten percent of junior securities deemed outstanding when exercised. The Stonepeak Warrant expires on the later of August 2, 2026 or 30 d ays following the full redemption of the Class C Preferred Units. There is no strike price associated with the exercise of the Stonepeak Warrant. The Stonepeak Warrant is accounted for as a liability in accordance with ASC 480 and is presented within other liabilities on the condensed consolidated balance sheet. Changes in the fair value of the Stonepeak Warrant are charged to interest expense in our condensed consolidated statements of operations. During the three months ended March 31, 2022 and 2021, we recorded interest expense related to the Class C Preferred distributions of approximately $14.4 million and $12.9 million, respectively, which are recorded in interest expense on the income statement. These are non-cash interest expense items. Earnings per Unit Net income (loss) per common unit for the period is based on any distributions that are made to the unitholders (common units) plus an allocation of undistributed net income (loss) based on provisions of our partnership agreement, divided by the weighted average number of common units outstanding. The two-class method dictates that net income (loss) for a period be reduced by the amount of distributions and that any residual amount representing undistributed net income (loss) be allocated to common unitholders and other participating unitholders to the extent that each unit may share in net income (loss) as if all of the net income for the period had been distributed in accordance with our partnership agreement. Unit-based awards granted but unvested are eligible to receive distributions. The underlying unvested restricted unit awards are considered participating securities for purposes of determining net income (loss) per unit. Undistributed income is allocated to participating securities based on the proportional relationship of the weighted average number of common units and unit-based awards outstanding. Undistributed losses (including those resulting from distributions in excess of net income) are allocated to common units based on provisions of our partnership agreement. Undistributed losses are not allocated to unvested restricted unit awards as they do not participate in net losses. Distributions declared and paid in the period are treated as distributed earnings in the computation of earnings per common unit even though cash distributions are not necessarily derived from current or prior period earnings. The Partnership’s general partner does not have an economic interest in the Partnership and, therefore, does not participate in the Partnership’s net income.

The accompanying financial statements include the accounts of us and our wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. These unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures, normally included in annual financial statements prepared in accordance with GAAP, have been condensed or omitted pursuant to those rules and regulations. We believe that the disclosures made are adequate to make the information presented not misleading. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary to fairly state the financial position, results of operations and cash flows with respect to the interim condensed consolidated financial statements have been included. The results of operations for the interim periods are not necessarily indicative of the results for the entire year. These unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2021, which was filed with the SEC on March 30, 2022.
Recent Accounting Pronouncements	Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”), which are adopted by us as of the specified effective date. Unless otherwise discussed, management believes that the impact of recently issued standards, which are not effective, will not have a material impact on our consolidated financial statements upon adoption. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This ASU modifies the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in more timely recognition of losses. Additionally, in November 2019, the FASB issued ASU 2019-10, “Financial Instruments – Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates,” which changed the effective date for certain issuers to annual and interim periods in fiscal years beginning after December 15, 2022, and earlier adoption is permitted. We are currently in the process of evaluating the impact of adoption of this guidance on our condensed consolidated financial statements. Other accounting standards that have been issued by the FASB or other standards-setting bodies are not expected to have a material impact on the Partnership’s financial position, results of operations and cash flows.
Use of Estimates	Use of Estimates The condensed consolidated financial statements are prepared in conformity with GAAP, which requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities and reported amounts of revenues and expenses. The estimates that are particularly significant to our financial statements include estimates of our reserves of natural gas, NGLs and oil; future cash flows from oil and natural gas properties; depreciation, depletion and amortization; asset retirement obligations; certain revenues and operating expenses; fair values of derivatives; and fair values of assets and liabilities. As fair value is a market-based measurement, it is determined based on the assumptions that market participants would use. These estimates and assumptions are based on management’s best judgment using the data available. Management evaluates its estimates and assumptions on an on-going basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. Such estimates and assumptions are adjusted when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ from the estimates. Any changes in estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.
