GLOSSARY OF OIL AND NATURAL GAS TERMS
The following is a glossary of certain oil and natural gas industry terms used in this Quarterly Report on Form 10-Q (this “report”):
BasinA large depression on the earth’s surface in which sediments accumulate.
Bbl or barrelOne stock tank barrel, or 42 U.S. gallons liquid volume, used in reference to crude oil, natural gas liquids or other liquid hydrocarbons.
Bbl/dBbl per day.
BOEBarrels of crude oil equivalent, with six thousand cubic feet of natural gas being equivalent to one barrel of oil.
BOE/dBoe per day.
British Thermal Unit or BtuThe quantity of heat required to raise the temperature of one pound of water by one degree Fahrenheit.
CompletionThe process of treating a drilled well, followed by the installation of permanent equipment for the production of natural gas or oil or, in the case of a dry hole, the reporting of abandonment to the appropriate agency.
CondensateLiquid hydrocarbons associated with production that is primarily natural gas.
Crude oilLiquid hydrocarbons found in the earth, which may be refined into fuel sources.
Dry hole or dry wellA well found to be incapable of producing hydrocarbons in sufficient quantities such that proceeds from the sale of such production exceed production expenses and taxes.
FieldThe general area encompassed by one or more crude oil or natural gas reservoirs or pools that are located on a single geologic feature, or that are otherwise closely related to such geologic feature (either structural or stratigraphic).
Hydraulic FracturingThe process of creating and preserving a fracture or system of fractures in a reservoir rock, typically by injecting a fluid under pressure through a wellbore and into the targeted formation.
Hydrocarbon
HydrocarbonAn organic compound containing only carbon and hydrogen.
IRSThe Internal Revenue Service.
MBblOne thousand barrels.
MBbl/dOne thousand barrels per day.
MBoeOne thousand barrels of crude oil equivalent, determined using a ratio of six Mcf of natural gas to one Bbl of crude oil, condensate or natural gas liquids.
Mcf
McfOne thousand cubic feet of natural gas.
Mcf/dOne thousand cubic feet of natural gas per day.
MMBblOne million barrels.
MMBbl/dOne million barrels per day.
MMBoeOne million barrels of crude oil equivalent.
MMBoe/dOne million barrels of crude oil equivalent per day.
MMBtu
MMBtuOne million British Thermal Units.
MMcfMMBtu/dOne million cubic feet of natural gas.British Thermal Units per day.
Natural GasgasHydrocarbon gas found in the earth, composed of methane, ethane, butane, propane and other gases.
NGLThe combination of ethane, propane, butane and natural gasolines that, when removed from natural gas, becomes liquid under various levels of higher pressure and lower temperature.
Operator
OperatorThe individual or company responsible for the exploration and/or production of a crude oil or natural gas well or lease.
PlayA set of discovered or prospective crude oil and/or natural gas accumulations sharing similar geologic, geographic and temporal properties, such as source rock, reservoir structure, timing, trapping mechanism and hydrocarbon type.
Plugging and abandonmentRefers to the sealing off of fluids in the strata penetrated by a well so that the fluids from one stratum will not escape into another or to the surface. Regulations of all states require plugging of abandoned wells.

ii


Reserves
ReservesEstimated remaining quantities of crude oil and natural gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations. In addition, there must exist, or there must be a reasonable expectation that there will exist, the legal right to produce or a revenue interest in the production, installed means of delivering crude oil and natural gas or related substances to the market and all permits and financing required to implement the project. Reserves should not be assigned to adjacent reservoirs isolated by major, potentially sealing, faults until those reservoirs are penetrated and evaluated as economically producible. Reserves should not be assigned to areas that are clearly separated from a known accumulation by a non-productive reservoir (i.e., potentially recoverable resources from undiscovered accumulations).
ReservoirA porous and permeable underground formation containing a natural accumulation of producible natural gas and/or crude oil that is confined by impermeable rock or water barriers and is separate from other reservoirs.
SWDSaltwater disposal.
Throughput
ThroughputThe volume of product transported or passing through a pipeline, plant, terminal or other facility.

We do not intend to, and disclaim any obligation to, update or revise any forward-looking statements unless required by securities laws. You should not place undue reliance on these forward-looking statements. These forward-looking statements are subject to a number of risks, uncertainties and assumptions. Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time.

1.    ORGANIZATION AND BASIS OF PRESENTATION

Organization

Rattler Midstream LP (the “Partnership”)The Partnership is a publicly traded Delaware limited partnership the common units of which are listedfocused on the Nasdaq Global Select Market under the symbol “RTLR”. The Partnership was formed on July 27, 2018 by Diamondback Energy, Inc. (“Diamondback”) to own, operate, developowning, operating, developing and acquireacquiring midstream infrastructure assets in the Midland and Delaware Basins of the Permian Basin. Unless the context requires otherwise, references to “we,” “us,” “our” or “the Partnership” are intended to mean the business and operations of the Partnership and its consolidated subsidiary, Rattler Midstream Partners LLC (the “Operating Company” and, prior to May 28, 2019 for accounting purposes, the "Predecessor").

On January 31, 2018, Diamondback, through its wholly-owned subsidiary Tall City Towers LLC (“Tall Towers”), acquired from Fasken Midland LLC (“Fasken Midland”) certain real property and related assets in Midland, Texas (the “Fasken Center”). Tall Towers was contributed to the Predecessor effective January 31, 2018, see Note 5—Acquisitions.

The Predecessor’s assets, contributed from Diamondback, included (i) crude oil and natural gas gathering and transportation systems, (ii) saltwater gathering and disposal systems and (iii) fresh water sourcing and distribution systems. All of the Partnership’s businesses are located or operate in the Permian Basin in West Texas.

Prior to the closing on May 28, 2019 of the Partnership’s initial public offering (the “IPO”) of 38,000,000 common units representing limited partner interests, Diamondback owned all of the general and limited partner interests in the Partnership. On May 30, 2019, the underwriters purchased an additional 5,700,000 common units following the exercise in full of their over-allotment option on the same terms, at a price to the public of $17.50 per common unit. The Partnership received net proceeds of approximately $719.6 million from the sale of these common units after deducting offering expenses and underwriting discounts and commissions.

In connection with the closing of the IPO, the Partnership (i) issued 107,815,152 Class B units representing an aggregate 71% voting limited partner interest in the Partnership in exchange for a $1.0 million cash contribution from Diamondback, (ii) issued a general partner interest in the Partnership to Rattler Midstream GP LLC (the “General Partner”) in exchange for a $1.0 million cash contribution from the General Partner, and (iii) caused the Operating Company to make a distribution of approximately $726.5 million to Diamondback. Diamondback, as the holder of the Class B units, and the General Partner, as the holder of the general partner interest, are entitled to receive cash preferred distributions equal to 8% per annum on the outstanding amount of their respective $1.0 million capital contributions, payable quarterly.

As of June 30, 2019,2021, the General Partner held a 100% general partner interest in the Partnership.Partnership and Diamondback ownsbeneficially owned all of the Partnership'sPartnership’s 107,815,152 outstanding Class B units, that provide a 71% voting interest.representing approximately 72% of the Partnership’s total units outstanding. Diamondback owns and controls the General Partner.

As of June 30, 2019,2021, the Partnership owned a 29%28% controlling membership interest in the Operating Company and Diamondback owned, through its ownership of the Operating Company units, a 71%72% economic, non-voting interest in the Operating Company. However, asAs required by GAAP, the Partnership consolidates 100% of the assets and operations of the Operating Company in its financial statements and reflects a non-controlling interest.interest attributable to Diamondback. In addition to the Operating Company, other consolidated subsidiaries of the Partnership include Tall City Towers LLC (“Tall Towers”), Rattler Ajax Processing LLC and Rattler OMOG LLC.

The Partnership also owns indirect interests in OMOG JV LLC (“OMOG”), EPIC Crude Holdings, LP (“EPIC”), EPIC Crude Holdings GP, LLC, Wink to Webster Pipeline LLC (“Wink to Webster”) and Gray Oak Pipeline, LLC (“Gray Oak”), which are accounted for as equity method investments as discussed further in Note 7— Equity Method Investments.

Basis of Presentation

Prior to May 28, 2019, the Partnership's services were performed by the Predecessor. The consolidated financial statements include the results of the Predecessor for the periods presented prior to the closing of the IPO on May 28, 2019. The Predecessor financial statements have been prepared from the separate records maintained by the Partnership and may not necessarily be indicative of the actual results of operations that might have occurred if the Predecessor had been operated separately during the periods reported.

The consolidated results of operations following the completion of the IPO are presented together with the results of operations pertaining to the Predecessor. The assets of the Predecessor consist of SWD wells and related gathering systems, office buildings, surface land and an oil gathering system and asset retirement obligations related to these assets, which were contributed effective January 1, 2019. See Note 5—Acquisitions. The capital contribution of the net proceeds from the IPO to the Operating Company in exchange for 29% of the limited liability company units of the Operating Company was accounted for as a combination of entities under common control, with assets and liabilities transferred at their carrying amounts in a manner similar to a pooling of interests. The Partnership did not own any assets prior to May 28, 2019, the date of the equity contribution agreement by and between the Partnership and the Predecessor. Prior to the IPO, the Predecessor was a wholly owned subsidiary of Diamondback. For periods prior to May 28, 2019, the accompanying condensed consolidated financial statements and related notes thereto represent the financial position, results of operations, cash flows and changeswere prepared in members’ equity of the Predecessor and, for periods on and after May 28, 2019, the accompanying consolidated financial statements and related notes thereto represent the financial position, results of operations, cash flows and changes in partners’ equity of the Partnership and its partially owned subsidiary.

The consolidated financial statements include the accounts of the Partnership and its subsidiaries after allaccordance with GAAP. All significant intercompany balances and transactions have been eliminated upon consolidation.

Prior to 2018, The Partnership reports its operations in 1 reportable segment. Effective in the Partnership's operations comprised a single operating business segment; however, withfirst quarter of fiscal 2021, the contribution of Tall Towers,Partnership determined the Partnership's operations are now reported in two operating business segments: (i) midstream services and (ii)former real estate operations. See Note 20—Reportoperations segment no longer met the criteria to be an operating segment due to a change in focus and the relative immateriality of Operating Business Segments.the activity.

These condensed consolidated financial statements have been prepared by the Partnership without audit, pursuant to the rules and regulations of the SEC. They reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results for interim periods, on a basis consistent with the annual audited financial statements. All such adjustments are of a normal recurring nature. Certain information, accounting policies and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been omitted pursuant to SEC rules and regulations, although the Partnership believes the disclosures are adequate to make the information presented not misleading. This Quarterly Report on Form 10–Q should be read in conjunction with the Partnership’s most recent prospectus statement dated May 22, 2019 and filed withAnnual Report on Form 10-K for the SEC pursuant to Rule 424(b) under the Securities Act on May 24, 2019,fiscal year ended December 31, 2020, which contains a summary of the Partnership’s significant accounting policies and other disclosures.

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period financial statement presentation. These reclassifications had no effect on the previously reported total assets, total liabilities, unitholders’ equity, results of operations or cash flows.

2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

As of June 30, 2019, the Partnership's significant accounting policies are consistent with those discussed in Note 2—Summary of Significant Accounting Policies of its consolidated financial statements contained in the final prospectus dated May 22, 2019 and filed with the SEC pursuant to Rule 424(b) under the Securities Act on May 24, 2019.

Use of Estimates

Certain amounts included in or affecting the Partnership’s financial statements and related notes must be estimated by management, requiring certain assumptions to be made with respect to values or conditions that cannot be known with certainty at the time the financial statements are prepared. These estimates and assumptions affect the amounts the Partnership reports for assets and liabilities and the Partnership’s disclosure of contingent assets and liabilities atas of the date of the financial statements.

Condensed Notes to Consolidated Financial Statements - Continued

Making accurate estimates and assumptions is particularly difficult in the oil and natural gas industry given the challenges resulting from volatility in oil and natural gas prices. For instance, in 2020, the effects of COVID-19, and actions by OPEC members and other exporting nations on the supply and demand in global oil and natural gas markets, resulted in significant negative pricing pressure in the first half of 2020, followed by a recovery in pricing and an increase in demand in the second half of 2020 and into 2021. Many companies in the oil and natural gas industry, including Diamondback, changed their business plans in response to changing market conditions. Such circumstances generally increase the uncertainty in the Partnership’s accounting estimates, particularly those involving financial forecasts.

The Partnership evaluates these estimates on an ongoing basis, using historical experience, consultation with experts and other methods they considerit considers reasonable in theeach particular circumstances.circumstance. Nevertheless, actual results may differ significantly from management’sthe Partnership’s estimates. Any effects on the Partnership’s business, financial position or results of operations resulting from revisions to these estimates are recorded in the period in which the facts that give rise to the revision become known. Significant items subject to such estimates and assumptions include, but are not limited to, (i) revenue accruals, (ii) the fair value of long-lived assets, and (iii) asset retirement obligations (“ARO”).and (iv) income taxes.

Income Taxes

The Partnership is treated as a corporation for U.S. federalfollowing table provides changes in the components of accumulated other comprehensive income, net of related income tax purposes as a result of its election to be treated as a corporation effective May 24, 2019. Subsequent to the effective date of the Partnership’s election, it is subject to U.S. federal and state income tax at corporate rates. The Partnership uses the asset and liability method of accounting for income taxes, under which deferred tax assets and liabilities are recognized for the future tax consequences of (i) temporary differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities and (ii) operating loss and tax credit carryforwards. Deferred income tax assets and liabilities are based on enacted tax rates applicable to the future period when those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period the rate change is enacted. A valuation allowance is provided for deferred tax assets when it is more likely than not the deferred tax assets will not be realized.effects (in thousands):

The Partnership is subject to margin tax in the state of Texas pursuant to the Tax Sharing Agreement with Diamondback, as discussed further in Note 15—Income Taxes. The Predecessor’s 2016 through 2018 tax years, the periods during which the Predecessor's sole owner, Diamondback, was responsible for federal income taxes on the Predecessor's taxable income, remain open to examination by tax authorities. As of June 30, 2019, the Partnership had no unrecognized tax benefits that would have a material impact on the effective tax rate. The Partnership is continuing its practice of recognizing interest and penalties related to income tax matters as interest expense and general and administrative expenses, respectively. During the three and six months ended June 30, 2019, there was no interest or penalties associated with uncertain tax positions recognized in the Partnership’s consolidated financial statements.

Capital Contributions

A contribution of a set of assets and related liabilities (a “set”) to the Partnership from Diamondback is analyzed to determine whether the set meets the definition of a business in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 805, “Business Combinations”. A contribution of a set of assets that does not constitute a business is recognized at the date of the transfer at its carrying amount in the accounts of Diamondback in accordance with the guidance regarding transactions between entities under common control in ASC 805-50. Management then evaluates whether the asset contribution results in a change in the reporting entity, as defined in ASC Topic 250, “Accounting Changes and Error Corrections”. An asset contribution that does not constitute a change in the reporting entity is accounted for prospectively from the date of the transfer, while an asset contribution that constitutes a change in the reporting entity would result in retrospective application of the transaction.

For the six months ended June 30, 2019, the total capital contributions by Diamondback to the Predecessor were $456.1 million, of which $9.2 million related to an office building located in Midland Texas, $18.1 million related to land, $9.4 million related to fresh water assets, $228.3 million related to SWD assets, $35.8 million related to crude oil assets, $149.5 million related to the equity method investments in the EPIC and Gray Oak projects, $31.1 million related to elimination of current and deferred liabilities, and $(25.3) million in additional assets and liabilities, net, related to operations.

In January 2018, the FASB issued ASU 2018-01, “Leases - Land Easement Practical Expedient for Transition to Topic 842”. This update applies to any entity that holds land easements. The update allows entities to adopt a practical expedient to not evaluate existing or expired land easements under Topic 842 that were not previously accounted for as leases under the current leases guidance. An entity that elects this practical expedient should evaluate new or modified land easements under Topic 842 beginning at the date that the entity adopts Topic 842. The Partnership adopted this update effective January 1, 2019. It did not have a material impact on its financial position, results of operations or liquidity.

In July 2018, the FASB issued ASU 2018-10, “Codification Improvements to Topic 842, Leases”. This update provides clarification and corrects unintended application of certain sections in the new lease guidance. This update was effective for financial statements issued for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. The Partnership adopted this update effective January 1, 2019. It did not have a material impact on its financial position, results of operations or liquidity.

In July 2018, the FASB issued ASU 2018-11, “Lease (Topic 842): Targeted Improvements”.

3.    REVENUE FROM CONTRACTS WITH CUSTOMERS

The Partnership generates revenues by charging fees on a per unit basis for gathering crude oil and natural gas, delivering and storing freshsourced water, and collecting, recycling and disposing of produced water. The Partnership adopted ASC Topic 606, “Revenue from Contracts with Customers” (“ASC Topic 606”) on January 1, 2018, using the modified retrospective method. Under ASC Topic 606, performance obligations are the unit of account and generally represent distinct goods or services that are promised to customers. The adoption of ASC Topic 606 did not have a material impact on the recognition, measurement and presentation of the Partnership’s revenues and expenses.

Performance Obligations: For gathering crude oil and natural gas, delivering fresh water, and collecting, recycling and disposing of produced water, the Partnership’s performance obligations are satisfied over time using volumes delivered to measure progress. The Partnership records revenue related to the volumes delivered at the contract price at the time of delivery.

The Partnership began generating revenue from water sales during first quarter 2018 upon the contribution of fresh water assets from Diamondback. For its water sales, each unit sold is generally considered a distinct good and the related performance obligation is generally satisfied at a point in time (i.e. at the time control of the water is transferred to the customer). The Partnership recognizes revenue from the sale of water when its contracted performance obligation to deliver water is satisfied and control of the water is transferred to the customer. This usually occurs when the water is delivered to the location specified in the contract and the title and risks of rewards and ownership are transferred to the customer.

Transaction Price Allocated to Remaining Performance Obligations: The majority of the Partnership’s revenue agreements have a term greater than one year and, as such, the Partnership has utilized the practical expedient in ASC Topic 606, which states that the Partnership is not required to disclose the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Under its revenue agreements, each delivery generally represents a separate performance obligation; therefore, future volumes delivered are wholly unsatisfied and disclosure of the transaction price allocated to remaining performance obligations is not required.

The remainder of the Partnership’s revenue agreements, which relate to agreements with third parties, are short-term in nature with a term of one year or less. The Partnership has utilized an additional practical expedient in ASC Topic 606 which exempts it from disclosure of the transaction price allocated to remaining performance obligations if the performance obligation is part of an agreement that has an original expected duration of one year or less.

Contract Balances: Under the Partnership’s revenue agreements, the Partnership invoices customers after our performance obligations have been satisfied, at which point payment is unconditional. As such, the Partnership’s revenue agreements do not give rise to contract assets or liabilities under ASC Topic 606.

The following is a summary of the Partnership’s types of revenue agreements:

Crude Oil Gathering Agreement. Under the crude oil gathering agreement, the Partnership receives a volumetric fee per barrel (Bbl) for gathering and delivering crude oil produced by Diamondback within the dedicated acreage.

Gas Gathering and Compression Agreement. Under the gas gathering and compression agreement, the Partnership receives a volumetric fee per million British Thermal Unit (MMBtu) for gathering and processing all natural gas produced by Diamondback within the dedicated acreage.

Produced and Flowback Water Gathering and Disposal Agreement. Under the produced and flowback water gathering and disposal agreement, the Partnership receives a fee for gathering or disposing of water produced from operating crude oil and natural gas wells within the dedicated acreage. The fee is comprised of a volumetric fee per Bbl for the produced water services the Partnership provides. In addition, the Partnership retains the skim oil that is a part of the produced water. The skim oil is processed by a third party, which provides the Partnership a volumetric fee per Bbl.

Fresh water Purchase and Services Agreement. Under the fresh water purchase and services agreement, the Partnership receives a fee for sourcing, transporting and delivering all raw fresh water and recycled fresh water required by Diamondback to carry out its oil and natural gas activities within the dedicated acreage. The fee is comprised of a volumetric fee per Bbl for the type of fresh water services the Partnership provides.

Real Estate Contracts: The Partnership recognizes rental revenue from tenants on a straight-line basis over the lease term when collectability is reasonably assured and the tenant has taken possession or controls the physical use of the leased asset. Rental income—related party is comprised of revenues earned from lease agreements with Diamondback and its affiliates. Other real estate revenue is derived from tenants’ use of parking, telecommunications and miscellaneous services. Parking and other miscellaneous service revenue is recognized when the related services are utilized by the tenants. Tenant recoveries related to reimbursement of real estate taxes, insurance, repairs and maintenance and other operating expenses are recognized as revenue in the period the applicable expenses are incurred. The reimbursements are recognized and presented gross, as the Partnership is generally the primary obligor with respect to purchasing goods and services from third-party suppliers, has discretion in selecting the supplier and bears the associated credit risk.

It is noted that surfaceSurface revenue, rental and real estate income and amortization of out of market leases isare outside the scope of ASC Topic 606.606, “Revenue from Contracts with Customers.”

4.    DIVESTITURES

On April 30, 2021, each of the Partnership and its joint venture partner, Amarillo Midstream, LLC, sold its 50% interest in Amarillo Rattler, LLC (“Amarillo Rattler”) to EnLink Midstream Operating, LP for aggregate total gross potential consideration of $75.0 million, consisting of $50.0 million at closing, $10.0 million upon the first anniversary of closing and up to $15.0 million in contingent earn-out payments over a three-year span based upon Diamondback's development activity. The earn-out payments are contingent on connected wells drilled in Diamondback’s leasehold acreage in the specified earn-out area during each year between 2023 and 2025. Net of transaction expenses and working capital adjustments, the Partnership received $23.5 million at closing, with an incremental $5.0 million due in April 2022, which resulted in a gain from sale of equity method investments of $23.0 million, which is included in gain (loss) on sale of equity method investments on the consolidated statement of operations. The Partnership’s share of the contingent earn-out payments, which cannot exceed $7.5 million in total over the three-year span, will be recorded if and when the contingent payments become realizable.

On June 28, 2021, the Partnership closed on the sale of 1 of its real estate properties located in Midland, Texas for proceeds of $9.1 million, including closing adjustments. The sale resulted in a loss on disposal of $1.6 million, which is included in (gain) loss on disposal of assets on the consolidated statement of operations.

8.    ASSET RETIREMENT OBLIGATIONSDepreciation expense related to property, plant and equipment was $13.8 million and $10.0 million for the three months ended June 30, 2021 and 2020, respectively, and $23.5 million and $20.5 million for the six months ended June 30, 2021 and 2020, respectively.

Asset retirement obligations consist primarilyCapitalized internal costs and capitalized interest related to property, plant and equipment were immaterial for the three and six months ended June 30, 2021 and 2020.

The Partnership evaluates its long-lived assets for potential impairment whenever events or circumstances indicate it is more likely than not that the carrying amount of the asset, or set of assets, is greater than the fair value. An impairment involves comparing the estimated costsfuture undiscounted cash flows of dismantlement, removal, site reclamation, plugging and abandonment and similar activities associatedan asset with the Partnership’s infrastructure assets. The following table reflectscarrying amount. If the changes incarrying amount of the Partnership’s asset retirement obligationexceeds the estimated future undiscounted cash flows, then an impairment charge is recorded for the following periods:

9.    EQUITY METHOD INVESTMENTS

In October 2014, Diamondback obtained a 25% interest in HMW Fluid Management LLC (“HMW LLC”), which was formed to develop, owndifference between the estimated fair value of the asset and operate an integrated water management system to gather, store, process, treat, distribute and dispose of water to exploration and production companies operating in Midland, Martin and Andrews Counties, Texas.

Onits carrying value. NaN such impairment charges were recorded during the three months ended June 30, 2018, HMW LLC’s operating agreement was amended. As a2021, or the three and six months ended June 30, 2020. It is possible that circumstances requiring additional impairment testing will occur in future interim periods, which could result in potentially material impairment charges being recorded. Abandonment charges of $3.4 million related to projects which had begun, but were later terminated, were recorded in depreciation, amortization and accretion on the amendment,consolidated statement of operations during the Partnership no longer recognizes an equity investment in HMW LLC but instead consolidates its undivided interest in the salt water disposal assets owned by HMW LLC. In exchange for the Partnership’s 25% investment, the Partnership received a 50% undivided ownership interest in two of the four SWD wells and associated assets previously owned by HMW LLC. The Partnership’s basis in the assets is equivalent to its basis in the equity investment in HMW LLC.

Basic and diluted net incomeearnings per common unit is calculated using the two-class method. The two-class method is an earnings allocation proportional to the respective ownership among holders of common units and participating securities. Basic earnings per common unit is calculated by dividing net income by the weighted-average number of common units outstanding during the period. Diluted earnings per common unit also considers the dilutive effect of unvested common units granted under the LTIP, calculated using the treasury stock method.

13.    INCOME TAXES

Prior toThe following table provides the Partnership’s IPO, all of the membership interests of the Predecessor were owned by a single member. Under applicable federal income tax provisions, the Predecessor’s legal existence as an entity separate from its sole owner was disregardedprovision for U.S. federal income tax purposes. As a result, the Predecessor’s owner, Diamondback, was responsible for federal(benefit from) income taxes on its share ofand the Predecessor’s taxable income. Similarly, the Predecessor had no tax attributes such as net operating loss carryforwards because such tax attributes are treated for federal income tax purposes as attributable to the Predecessor’s owner.

In certain circumstances, GAAP requires or permits entities such as the Predecessor to account for income taxes under the principles of ASC Topic 740, "Income Taxes" ("ASC Topic 740"), notwithstanding the fact that the separate legal entity’s activity is attributed to its owner for income tax purposes. Accordingly, the Predecessor has applied the principles of ASC Topic 740 to its financial statements herein, for periods prior to the Partnership’s IPO, as if the Predecessor had been subject to taxation as a corporation. Consistent with the overall basis of presentation as described in Note 1—Organization and Basis of Presentation, for the three and six months ended June 30, 2019 and 2018, net income for the period prior to the Partnership’s IPO reflects income taxes based on federal and state income tax rates, net of federal benefit, applicable to the Predecessor as if it had been subject to taxation as a corporation. In connection with the completion of the IPO, an adjustment of $31.1 million to equity of the Predecessor was recorded for the elimination of current and deferred tax liabilities related to the period prior to the IPO.

For the three and six months ended June 30, 2019, net income for the period prior to the IPO reflects income tax expense of $7.4 million and $18.2 million, respectively, and net income for the period subsequent to the IPO reflects income tax expense of $1.4 million.

The effective2020 differed from amounts computed by applying the United States federal statutory tax rate to pre-tax income tax rates for the period, primarily due to net income attributable to the non-controlling interest and to state taxes, net of federal benefit. For the three and six months ended June 30, 2018, were 20.9%2021 and 21.6%,2020, the Partnership recorded discrete income tax expense related to unit-based compensation of $0.2 million and $0.3 million, respectively.

The Partnership’s total net deferred tax assets consist primarily of the tax basis over the financial statement carrying value of its investment in the Operating Company and of net operating loss carryforwards. In the second quarter of 2020, the Partnership recorded an adjustment through unitholders’ equity to the carrying value of its investment in the Operating Company, resulting in a decrease in the effective incomePartnership’s deferred tax rates forliability related to its investment in the threeOperating Company. As a result of management’s assessment each period, including consideration of all available positive and six months endednegative evidence, management continued to determine that it is more likely than not that the Partnership will realize its deferred tax assets as of June 30, 2019, as compared to the three2021 and six months ended June 30, 2018, is primarily due to net income attributable to the noncontrolling interest in 2019 periods subsequent to the Partnership’s IPO.2020.


16.14.    FAIR VALUE MEASUREMENTS

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs.

The fair value hierarchy is based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value. The Partnership’s assessment of the significance of a particular input to the fair value measurements requires judgment and may affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy. The Partnership uses appropriate valuation techniques based on available inputs to measure the fair values of its assets and liabilities.

Level 1 - Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets as of the reporting date.

Level 2 - Observable market-based inputs or unobservable inputs that are corroborated by market data. These are inputs other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date.

Level 3 - Unobservable inputs that are not corroborated by market data and may be used with internally developed methodologies that result in management’s best estimate of fair value.

Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement.

The Partnership estimates asset retirement obligations pursuant to the provisions of FASB ASC Topic 410, “Asset RetirementAssets and Environmental Obligations.” The initial measurement of asset retirement obligationsLiabilities Measured at fair value is calculated using discounted cash flow techniques and basedFair Value on internal estimates of future retirement costs associated with SWD wells. Given the unobservable nature of the inputs, including plugging costs and useful lives, the initial measurement of the ARO liability is deemed to use Level 3 inputs. See Note 8—Asset Retirement Obligations for further discussion of the Partnership’s asset retirement obligations.a Nonrecurring Basis

17.    LEASES

The Partnership leases certain compression assets and other equipment.

As discussed in Note 2—Summary of Significant Accounting Policies, the Partnership adopted ASC Topic 842 on January 1, 2019 using the optional transition method of adoption. The Partnership elected a package of practical expedients that together allows an entity to not reassess (i) whether a contract is or contains a lease, (ii) lease classification and (iii) initial direct costs. In addition, the Partnership elected the following practical expedients: (i) to not reassess certain land easements; (ii) to not apply the recognition requirements under the standard to short-term leases; (iii) to not reassess lease terms for lease terms on leases entered into prior to the effective date of adoption and (iv) lessor accounting policy election to exclude lessor costs paid directly by the lessee.

For leases where the Partnership is the lessee, the Partnership recorded a total of $1.2 million in right-of-use assets and corresponding new lease liabilities on its Consolidated Balance Sheet representing the present value of its future operating lease payments. Adoption of the standard did not require an adjustment to the opening balance of retained earnings. The discount rate used to determine present value was based on the rate of interest that the Partnership estimated it would have to pay to borrow (on a collateralized-basis over a similar term) an amount equal to the lease payments in a similar economic environment as of January 1, 2019. The Partnership is required to reassess the discount rate for any new and modified lease contracts as of the lease effective date.

The right-of-use assets and lease liabilities recognized upon adoption of ASC Topic 842 were based on the lease classifications, lease commitment amounts and terms recognized under the prior lease accounting guidance. Leases with an initial term of twelve months or less are considered short-term leases and are not recorded on the balance sheet.

The following table summarizes operating leaseprovides the fair value of financial instruments that are not recorded at fair value in the condensed consolidated balance sheets:

The fair value of the Operating Company’s revolving credit facility approximates its carrying value based on borrowing rates available to the Partnership for bank loans with similar terms and maturities and is classified as Level 2 in the three and six months endedfair value hierarchy. The fair value of the Notes was determined using the June 30, 2019:2021 quoted market price, a Level 1 classification in the fair value hierarchy.

After giving effect to the casesale of a known contingency, the Partnership accrues a liability when the loss is probable and the amount is reasonably estimable. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum amount of the range is accrued. The Partnership discloses information regarding loss contingencies when, in the judgment of management, it is reasonably possible a loss has been incurred.

ITEM 2.         MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section and auditedour unaudited condensed consolidated financial statements and relatednotes thereto presented in this report as well as our audited financial statements and notes thereto included in our final prospectus dated May 22, 2019 and filed with the SEC pursuant to Rule 424(b) under the Securities Act on May 24, 2019, and with the unaudited consolidated financial statements and related notes thereto presented in this QuarterlyAnnual Report on Form 10-Q.10-K for the year ended December 31, 2020. The following discussion contains “forward-looking statements” that reflect our future plans, estimates, beliefs and expected performance. Actual results and the timing of events may differ materially from those contained in these forward-looking statements due to a number of factors. See “Cautionary Statement Regarding Forward-Looking Statements.”

Overview

We are a growth-oriented Delaware limited partnership formed by Diamondback in July 2018 to own, operate, develop and acquire midstream infrastructure assets in the Midland and Delaware Basins of the Permian Basin, one of the most prolific oil producing areas in the world. We are the only publicly-traded, pure-play Permian midstream company focused on the Midland and Delaware Basins. have elected to be treated as a corporation for U.S. federal income tax purposes.

We provide crude oil, natural gas and water-related midstream services (including fresh water sourcing and transportation and saltwaterproduced water gathering and disposal) to Diamondback under long-term, fixed-fee contracts. As of June 30, 2019, the assets Diamondback has contributed to us include 814 miles of pipeline across the Midland and Delaware Basins with approximately 236,000 Bbl/d of crude oil gathering capacity, 80,000 Mcf/d of natural gas compression capability, 150,000 Mcf/d of natural gas gathering capacity, 2.829 MMBbl/d of SWD capacity and 575,000 Bbl/d of fresh water gathering capacity. In addition to theour midstream infrastructure assets, that Diamondback contributed to us, we own equity interests in twothree long-haul crude oil pipelines, which upon completion, will run from the Permian to the Texas Gulf Coast. In addition, we own equity interests in third-party operated gathering systems and processing facilities supported by dedications from Diamondback. We are critical to Diamondback’s growthdevelopment plans because we provide a long-term midstream solution to its increasing crude oil, natural gas and water-related services needs through our robust infield gathering systems and SWDproduced water disposal capabilities.

As of June 30, 2019,2021, our General Partner hadgeneral partner held a 100% general partner interest in us and Diamondback ownedheld no common units and beneficially owned all of our 107,815,152 outstanding Class B units, representing approximately 71%72% of our total units outstanding.outstanding units. Diamondback also owns and controls our General Partner.general partner.

As of June 30, 2019,2021, we own a 29%28% controlling membership interest in the Operating Company and Diamondback owns, through its ownership of the Operating Company units, a 71%72% economic, non-voting interest in the Operating Company. However, as required by GAAP, we consolidate 100% of the assets and operations of the Operating Company in our financial statements and reflect a non-controlling interest.

Recent Developments
Initial Public Offering

COVID-19 and Commodity Prices
Prior
In early March 2020, oil prices dropped sharply and continued to decline briefly reaching negative levels as a result of multiple factors affecting the supply and demand in global oil and natural gas markets, including (i) actions taken by OPEC members and other exporting nations impacting commodity price and production levels, and (ii) a significant decrease in demand due to the closingCOVID-19 pandemic. However, certain restrictions on May 28, 2019conducting business that were implemented in response to the COVID-19 pandemic have since been lifted as improved treatments and vaccinations for COVID-19 have been rolled-out globally since late 2020. As a result, oil and natural gas prices have improved in response to the expected increase in demand for production.

We derive substantially all of our IPOrevenue from our commercial agreements with Diamondback, which do not contain minimum volume commitments. In response to the decrease in oil prices in early 2020 discussed above, Diamondback reduced its drilling and development plan on the acreage dedicated to us, which directly and adversely impacted Diamondback’s demand for our midstream services. Diamondback resumed completion activity to stem production declines and respond to rising commodity prices in the third and fourth quarters of 38,000,000 common units representing limited2020, but has kept production relatively flat during the first six months of 2021, using excess cash flows for debt repayment and to return capital to its stockholders rather than expanding its drilling program. As a result, we adjusted our operations to this new level of completion and production activity in the second half of 2020 and into 2021. We cannot predict the extent to which Diamondback’s business would be impacted if conditions in the energy industry were to deteriorate again, nor can we estimate the impact such conditions would have on Diamondback’s ability to execute its drilling and development plan on the dedicated acreage or to perform under our commercial agreements.

19

During 2021, we expect to reduce operated capital expenditures significantly to a level of less than half of 2020 amounts. Combined with our equity method joint venture build cycle nearing its end and changing from a net outflow of capital contributions to a net inflow of cash distributions, we believe that this stabilized volume outlook will present a meaningful free cash flow generation even in this volatile commodity price environment.

Divestitures

On April 30, 2021, we and our joint venture partner, interests, Diamondback owned all of the general and limited partnerAmarillo Midstream, LLC, each sold our respective 50% interests in our Predecessor. Amarillo Rattler to EnLink Midstream Operating, LP. Net of transaction expenses and working capital adjustments, we received $23.5 million at closing. An incremental $5.0 million is payable to us in April 2022, and we could receive up to $7.5 million in total contingent earn-out payments from 2023 to 2025.

On May 22, 2019,June 28, 2021, we priced 38,000,000 common units in our IPO at a price of $17.50 per share, andclosed on May 23, 2019 our common units began trading on the Nasdaq Global Select Market under the symbol “RTLR”. On May 30, 2019, the underwriters purchased an additional 5,700,000 common units following the exercise in full of their over-allotment option. We received estimated net proceeds of $719.6 million from the sale of these common units, after deductingone of our real estate properties located in Midland, Texas for proceeds of $9.1 million, including closing adjustments, which resulted in a loss on disposal of $1.6 million which is included in gain (loss) on disposal of property, plant and equipment on the underwriting discount and offering expenses.consolidated statement of operations.

Sources of Our IncomeRevenues
Our results are primarily driven by the volumes of crude oil that we gather, transport and deliver; natural gas that we gather, compress, transport and deliver; fresh water that we source, transport and deliver; and produced water that we gather, transport and dispose of, and the fees we charge per unit of throughput for our midstream services.
Our crude oil infrastructure assets consist of gathering pipelines and metering facilities, which collectively gather crude oil for our customers. Our facilities gather crude oil from horizontal and vertical wells in Diamondback’s ReWard, Spanish Trail, Pecos and Fivestones areas within the Permian. Our natural gas gathering and compression system consists of gathering pipelines, compression and metering facilities, which collectively service the production from Diamondback’s Pecos area assets within the Permian. Our fresh water sourcing and distribution assets consist of water wells, hydraulic fracturing pits, pipelines and water treatment facilities, which collectively gather and distribute water from Permian aquifers to the drilling and completion sites through buried pipelines and temporary surface pipelines. Our saltwater gathering and disposal system spans approximately 414 miles and consists of gathering pipelines along with SWD wells and facilities which collectively gather and dispose of saltwater from operations throughout Diamondback’s Permian acreage.
We have entered into multiplecurrently generate a substantial portion of our revenues under fee-based commercial agreements with Diamondback, each with an initial term ending in 2034, utilizing our infrastructure assets or our planned infrastructure assets to provide an array of essential services critical to Diamondback’s upstream operations on certain dedicated acreage in the Delaware and Midland Basins. Our agreements include substantial acreage dedications. Please read “Business—Our Acreage Dedication” included in our final prospectus dated May 22, 2019 and filed with the SEC pursuant to Rule 424(b) under the Securities Act on May 24, 2019.
We have indirect exposure to commodity price risk in that persistent low commodity prices may cause Diamondback or other customers to delay drilling or shut in production, which would reduce the volumes available for gathering and processing by our infrastructure assets. If Diamondback delays drilling or temporarily shuts in production due to persistently low commodity prices or for any other reason, our revenue could decrease, as our commercial agreements do not contain minimum volume commitments. Please read “Risk Factors—Risks Related to Our Business—Because of the natural decline in hydrocarbon production from existing wells, our success depends, in part, on our ability to maintain or increase hydrocarbon throughput volumes on our midstream systems, which depends on our customers’ levels of development and completion activity on our "Dedicated Acreage” and “Risk Factors—Risks Related to Our Business—Our construction of new midstream assets may not result in revenue increases and may be subject to regulatory, environmental, political, contractual, legal and economic risks, which could adversely affect our cash flow, results of operations and financial condition and, as a result, our ability to distribute cash to unitholders” included in our final prospectus dated May 22, 2019 and filed with the SEC pursuant to Rule 424(b) under the Securities Act on May 24, 2019.
Under each of our commercial agreements (other than the FERC-regulated crude oil gathering services agreement), the volumetric fees we charge are adjusted each calendar year by the amount of percentage change, if any, in the consumer price index from the preceding calendar year. No adjustment will be made if the percentage change would result in a fee below the initial fee set forth in the applicable commercial agreement and any adjustment to the volumetric fees shall not exceed 3% of the then-current fee. Further, the total adjustment of the fees shall never result in a cumulative volumetric fee adjustment of more than 30% of the initial fees set forth in the applicable commercial agreement. Please read “Business—Our Commercial Agreements with Diamondback” included in our final prospectus dated May 22, 2019 and filed with the SEC pursuant to Rule 424(b) under the Securities Act on May 24, 2019.

Recent Acquisitions
Effective January 1, 2019, Diamondback contributed to our Predecessor the Ajax Assets within the Permian Basin that it acquired from Ajax as part of an upstream acquisition in the fourth quarter of 2018. These assets included 17 water wells, four SWD wells and one related gathering system (35,000 Bbl/d of capacity), a field office, surface land, five hydraulic fracturing pits (4.4 MMBbls of capacity) and one related fresh water transportation system (25,000 Bbl/d of capacity). Prior to their contribution, these assets were fully integrated into the upstream business acquired from Ajax and used for disposal of produced water generated or fresh water sourcing when drilling. All assets contributed have estimated remaining useful lives of between 20-30 years.

Effective January 1, 2019, Diamondback contributed to our Predecessor the Energen Assets within the Permian Basin that it acquired from Energen as part of an upstream acquisition in the fourth quarter of 2018. These assets included 56 SWD wells (1.2 MMBbl/d of permitted capacity) and related gathering systems (1.0 MMBbl/d of capacity), an office building located in Midland Texas, surface land and an oil gathering system (16,000 Bbl/d of capacity). Prior to their contribution, these assets were fully integrated into the upstream business acquired from Energen and used for disposal of produced water generated or delivering oil under upstream contracts. All assets contributed have estimated remaining useful lives of 30 years.

Diamondback funded and our Predecessor acquired a 10% equity interest in each of the EPIC and Gray Oak projects, long-haul crude oil pipelines under development that we expect, following commencement of operations, will provide us with a steady, oil-weighted cash flow stream. These pipelines will also provide Diamondback with long-term long-haul transportation capacity for a portion of its Delaware and Midland Basin crude oil production. These pipelines will provide Diamondback a total takeaway capacity of up to 200,000 Bbl/d.

Principal Components of Our Cost Structure

General and Administrative

In connection with the closing of the IPO, we entered into the Services and Secondment Agreement with Diamondback under which we will pay fees to Diamondback with respect to certain operational services Diamondback will provide in support of our operations. The Partnership Agreement requires us to reimburse our General Partner for all direct and indirect expenses incurred or paid on our behalf and all other expenses allocable to us or otherwise incurred by our General Partner in connection with operating our business. The Partnership Agreement does not set a limit on the amount of expenses for which our General Partner and its affiliates may be reimbursed. These expenses include salary, bonus, incentive compensation and other amounts paid to persons who perform services for us or on our behalf and expenses allocated to our General Partner by its affiliates. Our General Partner is entitled to determine the expenses that are allocable to us.

Depreciation, Amortization and Accretion

This represents the depreciation, amortization and accretion on the assets and liabilities of the Operating Company.

Income Taxes

Prior to our IPO, our Predecessor was organized as a disregarded entity for income tax purposes. As a result, our Predecessor's sole owner, Diamondback, was responsible for federal income taxes on the Predecessor's taxable income. Subsequent to the IPO, we are subject to federal income taxes at the corporate statutory rate of 21%.

We are subject to the Texas margin tax. For the three and six months ended June 30, 2019, we accrued $31,814 for Texas margin tax payable pursuant to the Tax Sharing Agreement with Diamondback.

Other income (expense)

Interest income

This represents the interest received on our cash and cash equivalents.

Interest expense

We have financed a portion of our working capital requirements, capital expenditures and acquisitions with borrowings under our revolving credit facility. We incur interest expense that is affected by both fluctuations in interest rates and our financing decisions. We reflect interest paid to our lender in interest expense. In addition, we include the amortization of deferred financing costs (including origination and amendment fees), commitment fees and annual agency fees in interest expense.

Expense from equity investments

This represents our proportional expense from our equity investments.

Factors Affecting the Comparability of Our Financial Results

Our future results of operations may not be comparable to our Predecessor’s historical results of operations for the reasons described below:

Contribution of Midstream Assets

During the period from 2014 through 2017, Diamondback constructed and/or acquired various midstream and related assets located in the Delaware and Midland Basins, which Diamondback contributed to our Predecessor during fiscal years 2016 and 2017. These assets included 20 SWD wells and related gathering systems, two oil gathering systems, surface land, and other pipelines not yet placed into service. Prior to their contribution, these assets were fully integrated into Diamondback’s upstream operations.

Effective February 28, 2017, Diamondback contributed to our Predecessor certain midstream assets in the Pecos area within the Permian that it acquired from Brigham Resources Operating, LLC, Brigham Resources Midstream, LLC and other unrelated third parties. These assets included five SWD wells and seven hydraulic fracturing ponds across one main gathering system, and various pipelines and compression assets related to a gas gathering system and an oil gathering system, the majority of which were not yet in service. Prior to their contribution from Diamondback, these assets were owned by Brigham and were fully integrated into Brigham’s upstream operations where the assets were already in service. All of the assets contributed have estimated remaining useful lives of between 20-30 years.


Effective January 1, 2018, Diamondback contributed to our Predecessor the Fresh Water Assets located within the Permian Basin. These assets included numerous fresh water wells and 28 hydraulic fracturing ponds, located across nine fresh water transportation systems, that had previously been used to store and transport fresh water for Diamondback’s drilling operations. All of the assets contributed have estimated remaining useful lives of between 20-30 years.

Throughout 2018, Diamondback continued to assist our Predecessor in the construction of various other gathering assets, which included additional oil and gas and produced water pipelines, SWD wells and hydraulic fracturing ponds. These assets were never used as part of upstream operations, but were contributed immediately upon completion.

Effective January 1, 2019, Diamondback contributed to our Predecessor the Ajax Assets within the Permian Basin that it acquired from Ajax as part of an upstream acquisition in the fourth quarter of 2018. These assets included 17 water wells, four SWD wells and one related gathering system (35,000 Bbl/d of capacity), a field office, surface land, five hydraulic fracturing pits (4.4 MMBbls of capacity) and one related fresh water transportation system (25,000 Bbl/d of capacity). Prior to their contribution, these assets were fully integrated into the upstream business acquired from Ajax and used for disposal of produced water generated or fresh water sourcing when drilling. All assets contributed have estimated remaining useful lives of between 20-30 years.

Effective January 1, 2019, Diamondback contributed to our Predecessor the Energen Assets within the Permian Basin that it acquired from Energen, as part of an upstream acquisition in the fourth quarter of 2018. These assets included 56 SWD wells (1.2 MMBbl/d of permitted capacity) and related gathering systems (1.0 MMBbl/d of capacity), an office building located in Midland, Texas, surface land and an oil gathering system (16,000 Bbl/d of capacity). Prior to their contribution, these assets were fully integrated into the upstream business acquired from Energen and used for disposal of produced water generated or delivering oil under upstream contracts. All assets contributed have estimated remaining useful lives of 30 years.

Contribution of Fasken Center

Effective January 31, 2018, Diamondback contributed to our Predecessor all of its membership interest in its wholly-owned subsidiary, Tall Towers, which acquired from Fasken Midland LLC on January 31, 2018 certain real property consisting of land and two office towers in Midland, Texas, which we refer to as the Fasken Center, for a purchase price of approximately $110.0 million. With the asset contribution, our Predecessor also acquired third-party leases, which were valued as part of Diamondback’s purchase price. All of the assets contributed have estimated remaining useful lives of between 15-30 years.

Equity Investments

On February 1, 2019, Diamondback funded and our Predecessor acquired a 10% equity interest in the EPIC project and on February 15, 2019, Diamondback funded and our Predecessor acquired a 10% equity interest in the Gray Oak project.

Revenues

Prior to their contribution to our Predecessor, infrastructure assets were part of the integrated operations of Diamondback and were financed from cash flows from operations and funding from Diamondback. Commencing January 1, 2016, our Predecessor began to earn revenues under our long-term commercial agreements with Diamondback and began receiving separate fixed fees for the midstream services that we provide.

Our Predecessor real estate assets were contributed by Diamondback effective January 31, 2018 and we earn revenue from these assets through various lease agreements.

Operating Expenses

In connection with our IPO, we entered into the Services and Secondment Agreement with Diamondback under which we pay fees to Diamondback with respect to certain operational services Diamondback provides in support of our operations. Our Predecessor recorded direct costs of running our businesses as well as certain costs allocated

from Diamondback. As such, we expect that there will be differences in the results of our operations between our Predecessor’s historical financial statements and our future financial statements.

General and Administrative Expenses

Our Predecessor’s general and administrative expense included an allocation of charges for the management and operation of our assets by Diamondback for general and administrative services, such as information technology, treasury, accounting, human resources and legal services and other financial and administrative services. Following the completion of our IPO, Diamondback charges us a combination of direct and allocated charges for general and administrative services pursuant to the Partnership Agreement and the Services and Secondment Agreement.

We anticipate incurring approximately $1.4 million annually of incremental general and administrative expenses attributable to being a publicly traded partnership, which includes expenses associated with annual, quarterly and current reporting with the SEC, tax return preparation, Sarbanes-Oxley compliance, listing on Nasdaq, independent auditor fees, legal fees, investor relations expenses, transfer agent and registrar fees, incremental salary and benefits costs of seconded employees, outside director fees and insurance expenses. These incremental general and administrative expenses and the variable component of the general and administrative costs that we anticipate incurring under the Services and Secondment Agreement are not reflected in our historical financial statements.

Financing

There are differences in the way we will finance our operations as compared to the way our Predecessor historically financed operations. Historically, our Predecessor’s operations were financed as part of Diamondback’s integrated operations. Our sources of liquidity following our IPO include cash generated from operations and borrowings under our new revolving credit facility.

Income Taxes

Income tax expense includes U.S. federal and state taxes on operations, as applicable. Prior to our IPO, our Predecessor was organized as a disregarded entity for income tax purposes. As a result, our Predecessor’s sole owner, Diamondback, was responsible for federal income taxes on our Predecessor’s taxable income. Even though we are organized as a limited partnership under state law, we are treated as a corporation for U.S. federal income tax purposes and are subject to U.S. federal and state income tax at corporate rates, subsequent to the effective date of our election to be treated as a corporation. As such, our net income for the three and six months ended June 30, 2019 reflects a provision for income taxes for the period subsequent to our IPO. For the periods prior to our IPO, net income for the three and six months ended June 30, 2019 and 2018 reflects on a pro forma basis, a provision for income taxes as if our Predecessor had been treated as a corporation for U.S. federal income tax purposes.

Other Factors Impacting Our Business

We expect our business to continue to be affected by the following key factors. 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.

Supply and Demand for Crude Oil and Natural Gas

We currently generate a substantial portion of our revenues under fee-based commercial agreements with Diamondback. We expect these contracts to promote cash flow stability and minimize our direct exposure to commodity price fluctuations, since we generally do not own any of the crude oil, natural gas or water that we gather and do not engage in the trading of crude oil or natural gas. However, the volumetric fees we charge are adjusted each calendar year by the amount of percentage change, if any, in the consumer price index from the preceding calendar year. No adjustment will be made if the percentage change would result in a fee below the initial fee set forth in the applicable commercial agreement and any adjustment to the volumetric fees shall not exceed 3% of the then-current fee. Further, the total adjustment of the fees shall never result in a cumulative volumetric fee adjustment of more than 30% of the initial fees set forth in the applicable commercial agreement.


Additionally, commodityCommodity price fluctuations indirectly influence our activities and results of operations over the long-term, since they can affect production rates and investments by Diamondback and third-parties in the development of new crude oil and natural gas reserves. Generally, drilling and production activity will increase as crude oil and natural gas prices increase. Our throughput volumes depend primarily on the volumes of crude oil and natural gas produced by Diamondback in the Permian and, with respect to fresh water, the number of wells drilled and completed. Commodity prices are volatile and influenced by numerous factors beyond our or Diamondback’s control, including the domestic and global supply of and demand for crude oil and natural gas. The commodities trading markets, as well as other supply and demand factors, may also influence the selling prices of crude oil and natural gas. Furthermore, our ability to execute our growthdevelopment strategy in the Permian will depend on crude oil and natural gas production in that area, which is also affected by the supply of and demand for crude oil and natural gas.

Regulatory Compliance

The regulation of crude oil and natural gas gathering and transportation and water services activities by federal and state regulatory agencies has a significant impact on our business. Please read “Business—Regulation of Operations” included in our final prospectus dated May 22, 2019 and filed with the SEC pursuant to Rule 424(b) under the Securities Act on May 24, 2019. Our operations are also impacted by new regulations, which have increased the time that it takes to obtain required permits.

Additionally, increased regulation of crude oil and natural gas producers in our areas of operation, including regulation associated with hydraulic fracturing, could reduce regional supply of crude oil, natural gas and water and, therefore, throughput on our infrastructure assets. For more information, see “Business—Regulation of Operations” included in our final prospectus dated May 22, 2019 and filed with the SEC pursuant to Rule 424(b) under the Securities Act on May 24, 2019.

Comparison of the Three Months Ended June 30, 20192021 and 20182020 and Six Months Ended June 30, 2021 and 2020

Revenues.

Revenues increased by $62.0$12.4 million or 124%, to $111.8$101.1 million for the three months ended June 30, 20192021 from $49.8$88.7 million for the three months ended June 30, 2018. This increase was2020, primarily due to increasedan increase in sourced water, produced water and gas volumes. The increase in these volumes stems from an overall recovery in Diamondback’s drilling and production activities after curtailments in the second quarter of 2020 in response to the COVID-19 pandemic and other economic factors.

Revenues decreased by $18.2 million to $199.9 million for the six months ended June 30, 2021 from $218.1 million for the six months ended June 30, 2020. This decrease relates primarily to a reduction in sourced water, produced water and oil volumes due to Diamondback’s lower level of drilling and completion activity in first quarter of 2021. In addition, the February 2021 winter storms in the Permian Basin caused the further loss of approximately four to five days of Diamondback’s total net production. This decrease was partially offset by an increase in gas volumes largely due to the contributioncontinued build out of certain crude oil gathering, SWD wells and land and buildingsmidstream assets that Diamondback acquired pursuant to the Ajax acquisition and the Energen acquisition, which Diamondback contributed to us, on January 1, 2019, as well as the additional build out of historical Partnership systems.



Direct Operating Expense. Expenses

Direct operating expense was $26.3 million and $58.8 million for the three and six months ended June 30, 2021, respectively, compared to $37.4 million and $70.3 million for the three and six months ended June 30, 2020. The decreases in the 2021 periods compared to the 2020 periods are largely due to a focus on cost cutting efforts along with a reduction in expenses related to declining volumes in 2021.

Cost of Goods Sold

Cost of goods sold (exclusive of depreciation and amortization) increased by $15.4$5.6 million or 140%, to $26.4$10.3 million for the three months ended June 30, 20192021 from $11.0 million for three months ended June 30, 2018. This increase was primarily due to increased volumes largely due to the contribution of certain crude oil gathering, SWD wells and land and buildings that Diamondback acquired pursuant to the Ajax acquisition and the Energen acquisition, which Diamondback contributed to us on January 1, 2019, as well as the additional build out of historical Partnership systems.

Cost of Goods Sold. Cost of goods sold expense increased by $7.6 million, or 92%, to $15.8$4.7 million for the three months ended June 30, 2019 from $8.3 million for the three months ended June 30, 2018. The increase relates to the increased build out of historical fresh water systems of the Operating Company.

Real Estate Operating Expenses. Real estate operating expense increased by $0.2 million, or 29%, to $0.7 million for the three months ended June 30, 2019 from $0.5 million for the three months ended June 30, 2018.2020. The increase primarily relates to the addition of new tenants.

Depreciation, Amortization and Accretion. Depreciation, amortization and accretion expense increased by $4.2 million, or 70%, to $10.2 million for the three months ended June 30, 2019 from $6.0 million for the three months ended June 30, 2018. This increase was primarilyhigher sourced water volumes due to asset contributions fromDiamondback’s increased level of drilling and completion activity in the second quarter of 2021 compared to the second quarter of 2020 during which Diamondback curtailed a portion of its drilling and further development of existing gathering, transportation and disposal systems.completion activity.


GeneralCost of goods sold (exclusive of depreciation and Administrative Expense. General and administrative expense increasedamortization) decreased by $2.6$1.6 million to $3.1 million for the three months ended June 30, 2019 from $0.4 million for the three months ended June 30, 2018. This increase was primarily due to increased shared service allocations and additional professional service fees due to business growth and the contribution of additional midstream assets.

Expense from Equity Investments. Expense from equity investments decreased by $1.3 million, or 92%, from$1.5 million for the three months ended June 30, 2018 to $0.1 million for the three months ended June 30, 2019. The expense from equity investments for the three months ended June 30, 2019 was due to interest expense incurred on Gray Oak's promissory note. The expense from equity investments for the three months ended June 30, 2018 was due to the de-recognition of income from HMW LLC, which we no longer recognize as an equity investment.

(Gain) loss on Sale of Property, Plant and Equipment. Loss on sale of property, plant and equipment was $2.6 million for the three months ended June 30, 2018, and was due to the exchange of interest in SWD assets.

Provision for Income Taxes. We recorded income tax expense of $8.7 million and $4.1 million for the three months ended June 30, 2019 and 2018, respectively. The change in our income tax provision was primarily due to an increase in pre-tax income for the three months ended June 30, 2019, partially offset by the impact of net income attributable to non-controlling interest for the 2019 period subsequent to our IPO. Total income tax expense for the three months ended June 30, 2019 differed from amounts computed by applying the federal statutory tax rate to pre-tax income for the period primarily due to net income attributable to the non-controlling interest.

This increase2020. The decrease primarily relates to increaseda reduction in sourced water volumes largely due to Diamondback’s lower level of drilling and completion activity in the contributionfirst quarter of certain crude oil gathering, SWD wells2021, which was partially offset by an increased level of drilling and land and buildings that Diamondback acquired pursuant tocompletion activity in the Ajax acquisition and the Energen acquisition, which Diamondback contributed to us on January 1, 2019,second quarter of 2021 as well as the additional build out of historical Partnership systems.discussed above.

Non-GAAP Financial Measures
Depreciation, Amortization and Accretion
. Depreciation, amortization and accretion expense increased by $8.3 million, or 70%, to $20.1 million for the six months ended June 30, 2019 from $11.8 million for the six months ended June 30, 2018. This increase was primarily due to asset contributions from Diamondback and further development of existing gathering, transportation and disposal systems.

General and Administrative Expense. General and administrative expense increased by $3.8 million to $4.4 million for the six months ended June 30, 2019 from $0.7 million for the six months ended June 30, 2018. This increase was primarily due to increased shared service allocations and additional professional service fees due to business growth and the contribution of additional midstream assets.

Expense from Equity Investments. Expense from equity investments was $0.1 million for the six months ended June 30, 2019, and was related to interest expense incurred on Gray Oak's promissory note. There was no income or expense from equity investments for the six months ended June 30, 2018.

(Gain) loss on Sale of Property, Plant and Equipment. Loss on sale of property, plant and equipment was $2.6 million for the six months ended June 30, 2018, and was due to the exchange of interest in SWD assets.

Provision for Income Taxes. We recorded income tax expense of $19.6 million and $8.2 million for the six months ended June 30, 2019 and 2018, respectively. The change in our income tax provision was primarily due to an increase in pre-tax income for the six months ended June 30, 2019, partially offset by the impact of net income attributable to non-controlling interest for the 2019 period subsequent to our IPO. Total income tax expense for the six months ended June 30, 2019 differed from amounts computed by applying the federal statutory tax rate to pre-tax income for the period primarily due to net income attributable to the non-controlling interest.

Adjusted EBITDA

Adjusted EBITDA is a supplemental non-GAAP financial measure used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies. We believe Adjusted EBITDA is useful because it allows us to more effectively evaluate our operating performance and compare the results of our operations period to period without regard to our financing methods or capital structure.

We define Adjusted EBITDA as net income before(loss) attributable to Rattler Midstream LP plus net income taxes,(loss) attributable to non-controlling interest before interest expense net(net of amount capitalized, interest expense related to equity investments, non-cash unit-based compensation expense and depreciation, amortization and accretion.  Depreciation, amortization and accretion includescapitalized), depreciation, amortization and accretion on assets and liabilities of the Operating Company, in addition toour proportional depreciation amortization and accretion on our equity investments. Interestinterest expense related to equity method investments, represents our proportional impairments and abandonments related to equity method investments, non-cash unit-based compensation expense, impairment and abandonments, (gain) loss on disposal of assets, (gain) loss from sale of equity method investment, provision for income (loss) from equity investments plus interest on that amount.taxes and other. The GAAP measure most directly comparable to Adjusted EBITDA is net income. income (loss). However, Adjusted EBITDA is not a measure of net income (loss) as determined by GAAP. We exclude the items listed above from net income (loss) in arriving at Adjusted EBITDA because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Certain items excluded from Adjusted EBITDA are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as historic costs of depreciable assets.

Adjusted EBITDA should not be considered an alternative to net income (loss) or any other measure of financial performance or liquidity presented in accordance with GAAP. Our computation of Adjusted EBITDA excludes some, but not all, items that affect net income (loss), and these measures may vary from those of other companies. As a result, Adjusted EBITDA as presented below may not be comparable to similarly titled measures of other companies.

Liquidity and Capital Resources

Liquidity and Financing Arrangements

Overview
Our sources of liquidly and capital resources are provided by operating cash flow, cash on hand, borrowings under our revolving credit facility, and capital market transactions. We believe the combination of these capital resources will be sufficient to meet our working capital requirements, expected quarterly cash distributions and fund our operations through year-end 2019.

Historically, ourOur primary sources of liquidity were based on cash flow from operations and funding from Diamondback.

We do not have any commitment from Diamondback or our General Partner or any of their respective affiliates to fund our cash flow deficits or provide other direct or indirect financial assistance to us. Our sources of liquidity following the IPO includebeen cash generated from operations, borrowings under our new revolving credit facilitythe Credit Agreement and if necessary, the issuance of additional equity or debt securities.the Notes. We believe that cash generated from these sources will be sufficient to meet our short-term working capital requirements and long-term capital expenditure requirements and to make quarterly cash distributions. We do not have any commitment from Diamondback, our general partner or any of their respective affiliates to fund our cash flow deficits or provide other direct or indirect financial assistance to us. Should we require additional capital, the indirect effect of volatile commodity markets and/or adverse macroeconomic conditions may limit our access to, or increase our cost of, capital or make capital unavailable on terms acceptable to us or at all.

Cash Distributions on Common Units

On August 2, 2021, the board of directors of our general partner approved a cash distribution for the second quarter of 2021 of $0.25 per common unit, payable on August 23, 2021, to common unitholders of record at the close of business on August 16, 2021. The board of directors of our General Partner adopted a cashgeneral partner may change the distribution policy pursuantat any time and from time to which we will distribute $0.25 per common unit within 60 days after the end of each quarter, beginning with the quarter ending September 30, 2019, subject to applicable lawtime. See Note 10 Unitholders’ Equity and our obligations under certain contractual agreements. Please read “Cash Distribution Policy and Restrictions on Distributions" Distributionsincluded in the condensed notes to the consolidated financial statements included elsewhere in this report for additional discussion of our final prospectus dated May 22, 2019 and filed with the SEC pursuant to Rule 424(b) under the Securities Act on May 24, 2019.distribution policy.

The increase was2020, due to increased operations as additional assets have been placed into service and the contribution of certain crude oil gathering, SWD wells and land and buildings that Diamondback acquired pursuantprimarily to the Ajax acquisition$18.2 million decline in revenues and an increase in cash paid for interest of $9.2 million. These decreases were partially offset by reductions of $11.5 million in direct operating expenses and $1.6 million in cost of goods sold, and distributions representing returns on investment from our equity method investments of $9.1 million. The remaining decrease stems from largely offsetting changes in working capital due primarily to the Energen acquisition, which Diamondback contributedtiming of when collections are made on accounts receivable and payments are made on accounts payable and accrued liabilities. See Results of Operations for further discussion of changes in revenue, operating expenses and interest expense and Note 7 — Equity Method Investments included in the condensed notes to us on January 1, 2019.the consolidated financial statements included elsewhere in this report for further discussion of distributions.

Investing Activities

Net cash provided by investing activities was $17.8 million during the six months ended June 30, 2021, and primarily consists of $23.5 million of proceeds from the sale of our Amarillo Rattler equity method investment, $9.1 million in proceeds from the sale of a real estate asset, and $9.1 million in distributions considered to be returns of investment received from our equity method investments. These proceeds were partially offset by capital expenditures for property, plant and equipment of $17.7 million and contributions to our equity method investments of $6.5 million, which continue to decrease as discussed in Recent Developments.

Net cash used in investing activities was $140.3 million and $84.7$139.7 million during the six months ended June 30, 2019 and 2018, respectively,2020, and primarily related to additions to property, plant and equipment and contributions to our EPIC andequity method investments, which were partially offset by distributions considered to be returns of investment received from our Gray Oak and OMOG equity method investments. See Note 9—Equity Method Investments.

Financing Activities

Net cash used in financing activities was $3.9$152.6 million during the six months ended June 30, 2019,2021, and primarily related to (i) distributions of $59.6 million to our unitholders, (ii) net proceeds frompayments on the credit facility of $74.0 million as we continue to reduce our IPOborrowings and (iii) $16.3 million in repurchases of common units under our repurchase program during the period.

Net cash provided by financing activities was $8.4 million during the six months ended June 30, 2020, and primarily related to proceeds from borrowings on the Operating Company’s revolving credit facility of $719.6 million, a contribution of $1.0 million from our General Partner for its general partner interest in the Partnership, a contribution of $1.0 million from Diamondback for its Class B units and borrowings, net of repayment of $1.0$99.0 million, partially offset by distributions to our unitholders of $726.5$88.0 million during the period.

Common Unit Repurchase Program

On October 29, 2020, the board of directors of our general partner approved a common unit repurchase program to acquire up to $100 million of our outstanding common units. The common unit repurchase program is authorized to extend through December 31, 2021 and we intend to purchase common units under the repurchase program opportunistically with cash providedon hand and free cash flow from operations. The repurchase program may be suspended from time to time, modified, extended or discontinued by or used in financing activities duringthe board of directors of our general partner at any time. During the six months ended June 30, 2018.2021, we repurchased approximately $16.3 million of common units under the repurchase program. As of June 30, 2021, $68.9 million remained available for use to repurchase common units under our program.

Capital Requirements and Sources of Liquidity

The midstream energy business is capital intensive, requiring the maintenance of existing gathering systems and other midstream assets and facilities and the acquisition or construction and development of new gathering systems and other midstream assets and facilities. However, with respect to capital expenditures incurred for acquisitions or capital improvements, we have some discretion and control. In times of reduced operational activity, we may choose to defer a portion of our budgeted capital expenditures until later periods to achieve the desired balance between sources and uses of liquidity and prioritize capital projects that we believe have the highest expected returns and potential to generate near-term cash flow. Subject to financing alternatives, we may also increase our capital expenditures significantly to take advantage of opportunities we consider to be attractive. We consistently monitor and may adjust our projected capital expenditures in response to factors both within and outside our control.
For the six months ended June 30, 2021, our total capital expenditures were $17.7 million, which primarily consisted of $13.9 million related to produced water disposal assets, $1.2 million related to crude oil gathering assets, $1.3 million related to natural gas gathering assets, and $1.2 million related to real estate assets. We estimate that our total capital expenditures related to midstream assets for 20192021 will be between $225.0$30 million and $250.0$50 million, excluding our anticipated total capital commitments associated withrelated to our equity interest in certain pipeline projects. Formethod investments of approximately $5 million to $15 million. We also estimate that distributions from our equity method investments will be between $35 million to $45 million. However, this range could decrease due to the six months ended June 30, 2019, our total capital expenditures were $102.9 million,continued impact, either directly or indirectly, of which $43.9 million were related to SWD assets, $21.1 million were related tothe COVID-19 pandemic or volatile crude oil gathering assets, $16.1 million were relatedprices on our business.
We own equity interests in the EPIC, Gray Oak, Wink to natural gas gathering assets, $21.2 million were related to fresh water assetsWebster and $0.6 million were related to other assetsOMOG joint ventures. Each of these joint ventures is accounted for using the equity method.

For further discussion regarding these investments see Note 7 — Equity Method Investment included in aggregate. With respectthe condensed notes to the Wink to Webster Pipeline, which we joined as a member on July 30, 2019, we expect capital contributions for the balance of 2019 to be less than $20 million.consolidated financial statements included elsewhere in this report.


Based upon current expectations for 2019,2021, we believe that our cash flowflows from operations, cash on hand and borrowing under our revolving credit facility will be sufficient to fund our operations and anticipated future capital commitments through year-end 2019.the 12-month period following the filing of this report and thereafter.

The Operating Company’s Revolving Credit AgreementFacility

The Operating Company’s credit agreement provides for a revolving credit facility in the maximum credit amount of $600 million. Loan principal may be optionally repaid from time$600.0 million, which is expandable to time without premium or penalty (other than$1.0 billion upon our election, subject to obtaining additional lender commitments and satisfaction of customary LIBOR breakage), and is required to be paid at the maturity date of May 28, 2024. The loan is guaranteed by us and Tall City, and is secured by substantially all of our, the Operating Company and Tall City's assets.conditions. As of June 30, 2019, we had $1.02021, there was $5.0 million of outstanding borrowings, and $599.0$595.0 million available for future borrowings, under the Credit Agreement.

Operating Company’s revolving credit facility. The outstandingweighted average interest rate on borrowings under the Credit Agreement bear interest at a per annum rate elected by Rattler LLC that is based onwas 1.36% and 1.39% for the prime rate or LIBOR, in each case plus an applicable margin. The applicable margin ranges from 0.250% to 1.250% per annum for prime-based loansthree and 1.250% to 2.250% per annum for LIBOR loans, in each case depending on the Consolidated Total Leverage Ratio (as defined in the Credit Agreement). The Operating Company is obligated to pay a quarterly commitment fee ranging from 0.250% to 0.375% per annum on the unused portion of the commitment, which fee is also dependent on the Consolidated Total Leverage Ratio.

The Credit Agreement contains various affirmative and negative covenants. These covenants, among other things, limit additional indebtedness, additional liens, sales of assets, mergers and consolidations, distributions and other restricted payments, transactions with affiliates, and entering into certain swap agreements, in each case with us, the Operating Company and our restricted subsidiaries. The covenants are subject to exceptions set forth in the Credit Agreement, including an exception allowing the Operating Company or us to issue unsecured debt securities, and an exception allowing payment of distributions if no default exists. The Credit Agreement may be used to fund capital expenditures, to finance working capital, for general company purposes, to pay fees and expenses related to the Credit Agreement, and to make distributions permitted under the Credit Agreement.

The Credit Agreement also contains financial maintenance covenants that require the maintenance of the financial ratios described below:
Financial CovenantRequired Ratio
Consolidated Total Leverage Ratio commencing with the fiscal quarter ending September 30, 2019Not greater than 5.00 to 1.00 (or not greater than 5.50 to 1.00 for 3 fiscal quarters following certain acquisitions), but if the Consolidated Senior Secured Leverage Ratio (as defined in the Credit Agreement) is applicable, then not greater than 5.25 to 1.00)
Consolidated Senior Secured Leverage Ratio commencing with the last day of any fiscal quarter in which the Financial Covenant Election (as defined in the Credit Agreement) is madeNot greater than 3.50 to 1.00
Consolidated Interest Coverage Ratio (as defined in the Credit Agreement) commencing with the fiscal quarter ending September 30, 2019Not less than 2.50 to 1.00

For purposes of calculating the financial maintenance covenants prior to the fiscal quarter endingsix months ended June 30, 2020, EBITDA (as defined in the Credit Agreement) will be annualized based2021, respectively. The credit agreement matures on the actual EBITDA for the preceding fiscal quarters starting with the fiscal quarter ending September 30, 2019.May 28, 2024.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risk, including the effects of adverse changes in commodity prices and interest rates as described below. The primary objective of the following information is to provide quantitative and qualitative information about our potential exposure to market risks. The term “market risk” refers to the risk of loss arising from adverse changes in oil and natural gas prices and interest rates. The disclosures are not meant to be precise indicators of expected future losses, but rather indicators of reasonably possible losses.
Commodity Price Risk

We currently generate the majority of our revenues pursuant to fee-based agreements with Diamondback under which we are paid based on volumetric fees, rather than the underlying value of the commodity. Consequently, our existing operations and cash flowflows have little direct exposure to commodity price risk. However, Diamondback and our other customers are exposed to commodity price risk, and extended reduction in commodity prices could reduce the production volumes available for our midstream services in the future below expected levels. Although we intend to maintain fee-based pricing terms on both new contracts and existing contracts for which prices have not yet been set, our efforts to negotiate such terms may not be successful, which could have a materially adverse effect on our business.

We may acquire or develop additional midstream assets in a manner that increases our exposure to commodity price risk. Future exposure to the volatility of crude oil, natural gas and natural gas liquids prices could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to make cash distributions to our unitholders.

Credit Risk

We are subject to counterparty credit risk related to our midstream commercial contracts, lease agreements and joint venture receivables. We derive substantially all of our revenue from our commercial agreements with Diamondback, which agreements do not contain minimum volume commitments, as well as volumes attributable to third-party interest owners that participate in Diamondback’s operated wells and are charged under short-term contracts at market sensitive rates.Diamondback. As a result, we are subjectdirectly affected by changes to theDiamondback’s business related to operational and business risks of Diamondback, the most significant of which include the following:
a reduction in or slowing of Diamondback’s drilling and development plan on the dedicated acreage, which would directly and adversely impact Diamondback’s demand for our midstream services;
the volatility of crude oil, natural gas and natural gas liquids prices, which could have a negative effect on Diamondback’s drilling and development plan on the dedicated acreage or Diamondback’s ability to finance its operations and drilling and completion costs on that acreage;
the availability of capital on an economic basis to fund Diamondback’s exploration and development activities, if needed;
drilling and operating risks, including potential environmental liabilities, associated with Diamondback’s operations on the dedicated acreage;
future wells, or wells that are currently in the process of being completed, on acreage that is dedicated to us do not produce sufficient hydrocarbons or are dry holes, which would directly and adversely impact the hydrocarbon volumes on our systems and our revenue;
downstream processing and transportation capacity constraints and interruptions, including the failure of Diamondback to have sufficient contracted processing or transportation capacity; and
adverse effects of increased or changed governmental and environmental regulation or enforcement of existing regulation.
In addition, we are indirectly subject to the business risks of Diamondback generally and other factors; including, among others:
Diamondback’s financial condition, credit ratings, leverage, market reputation, liquidity and cash flow;
Diamondback’s ability to maintain or replace its reserves;
adverse effects of governmental and environmental regulation on Diamondback’s upstream operations; and
losses from pending or future litigation.

Further, we have no control over Diamondback’s business decisions and operations, and Diamondback is under no obligation to adopt a business strategy that is favorable to us. Thus, we are subject to the risk that Diamondback could cancel its planned development, breach its commitments with respect to future dedications or otherwise fail to pay or perform, including with respect to our commercial agreements.otherwise. We cannot predict the extent to which Diamondback’s businessesbusiness would be impacted if conditions in the energy industry were to deteriorate, nor can we estimate the impact such conditions would have on Diamondback’s ability to execute its drilling and development plan on the dedicated acreageprogram or to perform under our commercial agreements. Any material non-payment or non-performanceWhile we monitor the creditworthiness of purchasers, lessees and joint venture partners with which we conduct business, we are unable to predict sudden changes in solvency of these counterparties and may be exposed to associated risks. Nonperformance by Diamondback under our commercial agreements would have a counterparty could result in significant adverse impact on our business, financial condition, results of operations and cash flow and could therefore materially adversely affect our ability to make cash distributions to our common unitholders.
Our commercial agreements with Diamondback provide for temporary or permanent releases of volumes or acreage from the acreage dedication under certain circumstances. Any temporary or permanent release of volumes or acreage from the acreage dedication could materially adversely affect our business, financial condition, results of operations, cash flow and ability to make cash distributions. For more information, see “Business-Our Commercial Agreements with Diamondback” included in our final prospectus dated May 22, 2019 and filed with the SEC pursuant to Rule 424(b) under the Securities Act on May 24, 2019.
Our commercial agreements with Diamondback carry initial terms ending in 2034, and there is no guarantee that we will be able to renew or replace these agreements on equal or better terms, or at all, upon their expiration. Our ability to renew or replace our commercial agreements following their expiration at rates sufficient to maintain our current revenues and cash flow could be adversely affected by activities beyond our control, including the activities of federal and state regulators, our competitors and Diamondback.

The terms of our revolving credit facilitythe Credit Agreement provide for interest at a rate elected by the Operating Company that is based on the prime rate or LIBOR, in each case plus margins ranging from 0.250% to 1.250% for prime-based loans and 1.250% to 2.250% per annum for LIBOR loans, in each case depending on the Consolidated Total Leverage Ratio (as defined in the Credit Agreement). The Operating Company is obligated to pay a quarterly commitment fee ranging from 0.250% to 0.375% per annum on the unused portion of the commitment, which fee is also dependent on the Consolidated Total Leverage Ratio.
