Notes to Condensed Consolidated Financial Statements (Unaudited)
1. Organization and Nature of Operations
Organization.Oasis Midstream Partners LP (the 'Partnership') is a leading gathering and processing master limited partnership formed by its sponsor, Oasis Petroleum Inc. (together with its subsidiaries, 'Oasis Petroleum') to own, develop, operate and acquire a diversified portfolio of midstream assets in North America.
The Partnership conducts its business through its wholly-owned subsidiaries: Bighorn DevCo LLC ('Bighorn DevCo'), Bobcat DevCo LLC ('Bobcat DevCo'), Beartooth DevCo LLC ('Beartooth DevCo') and Panther DevCo LLC ('Panther DevCo' and collectively with Bighorn DevCo, Bobcat DevCo and Beartooth DevCo, the 'DevCos').
As of March 31, 2021, the Partnership's assets in the DevCos were as follows:
DevCo Areas Served Service Lines
Bighorn DevCo Wild Basin
-Natural gas processing
-Crude oil terminaling
-Crude oil transportation
Bobcat DevCo Wild Basin
-Natural gas gathering
-Natural gas compression
-Gas lift supply
-Crude oil gathering
-Produced and flowback water gathering
-Produced and flowback water disposal
Beartooth DevCo Alger
Cottonwood
Hebron
Indian Hills
Red Bank
Wild Basin
-Produced and flowback water gathering
-Produced and flowback water disposal
-Freshwater supply and distribution
Panther DevCo Permian Basin
-Crude oil gathering
-Produced and flowback water gathering
-Produced and flowback water disposal

Nature of business.The Partnership generates a substantial majority of its revenues through fee-based contractual arrangements with Oasis Petroleum for midstream services. These services include (i) gas gathering, compression, processing, gas lift supply and natural gas liquids ('NGLs') storage services; (ii) crude oil gathering, terminaling and transportation services; (iii) produced and flowback water gathering and disposal services; and (iv) freshwater supply and distribution services. The revenue earned from these services is generally directly related to the volume of natural gas, crude oil, produced and flowback water and freshwater that flows through the Partnership's systems.
The Partnership's operations are supported by significant acreage dedications from Oasis Petroleum and commitments from third party producers in the Williston Basin and the Permian Basin.
The Partnership is not a taxable entity for United States federal income tax purposes and is not subject to income tax in the majority of states in which the Partnership operates. As taxes are generally borne by its partners through the allocation of taxable income, the Partnership does not record deferred taxes related to the aggregate difference in the basis of its assets for financial and tax reporting purposes. The Partnership is subject to a Texas margin tax due to its operations in the Permian Basin and recorded a de minimis state income tax provision for the three months ended March 31, 2021.

2. Summary of Significant Accounting Policies
Basis of Presentation
The accompanying condensed consolidated financial statements of the Partnership have not been audited by the Partnership's independent registered public accounting firm, except that the Condensed Consolidated Balance Sheet at December 31, 2020 is derived from audited financial statements. In the opinion of management, all adjustments, consisting of normal recurring adjustments necessary for fair statement of the Partnership's financial position have been included. Management has made certain estimates and assumptions that affect reported amounts in the condensed consolidated financial statements and disclosures of contingencies. Actual results may differ from those estimates. The results for interim periods are not necessarily indicative of annual results.
These interim financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ('SEC') regarding interim financial reporting. Certain disclosures have been condensed or omitted from these financial statements. Accordingly, they do not include all of the information and notes required by accounting principles generally accepted in the United States of America ('GAAP') for complete consolidated financial statements and should be read in conjunction with the Partnership's audited consolidated financial statements and notes thereto included in the Partnership's Annual Report on Form 10-K for the year ended December 31, 2020 ('2020 Annual Report').
Simplification Transaction
On March 30, 2021, the Partnership closed the Simplification Transaction (defined below) with Oasis Petroleum to acquire Oasis Petroleum's remaining ownership interests in Bobcat DevCo and Beartooth DevCo. In addition, the Simplification Transaction eliminated the incentive distribution rights held by the General Partner (the 'IDRs') (see Note 4 - Transactions with Affiliates).
Prior to the Simplification Transaction, the Contributed Assets (defined below) were reflected as non-controlling interests in the Partnership's unaudited condensed consolidated financial statements. In accordance with FASB authoritative guidance under ASC 810-10 for non-controlling interests in a common control transaction, the Partnership accounted for the Simplification Transaction as an equity transaction and adjusted the carrying amount of non-controlling interests in the condensed consolidated financial statements to reflect the change in ownership interests. Furthermore, as the Partnership acquired additional interests in previously consolidated subsidiaries, the Simplification Transaction did not result in a change in reporting entity, as defined under the FASB Accounting Standards Codification Topic 805, Business Combinations, and was accounted for on a prospective basis.
Consolidation
The Partnership's condensed consolidated financial statements include its accounts and the accounts of the DevCos, each of which is a wholly-owned subsidiary of the Partnership and controlled by the Partnership through the General Partner. All intercompany balances and transactions have been eliminated upon consolidation.
Risks and Uncertainties
Concentrations of market and credit risk. The Partnership has limited direct exposure to risks associated with fluctuating commodity prices due to the nature of its business and its long-term, fixed-fee contractual arrangements with its existing customers, including Oasis Petroleum. However, to the extent that the Partnership's future contractual arrangements with customers, including Oasis Petroleum or third parties, do not provide for fixed-fee structures, the Partnership may become subject to more substantial direct commodity price risk. In addition, in response to a prolonged low commodity price environment, the Partnership's customers could seek to amend existing contractual arrangements to reduce the volumetric fees the Partnership charges.
As a substantial majority of the Partnership's revenues are derived from Oasis Petroleum, the Partnership is indirectly subject to risks associated with fluctuating commodity prices to the extent that lower commodity prices adversely affect Oasis Petroleum's production, drilling schedule or financial condition.
Significant Accounting Policies
There have been no material changes to the Partnership's critical accounting policies and estimates from those disclosed in the 2020 Annual Report.
Recent Accounting Pronouncements
Reference rate reform.In March 2020, the Financial Accounting Standards Board issued Accounting Standards Update 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting
6
Table of Contents
('ASU 2020-04'). The amendments provide optional guidance for a limited time to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying GAAP guidance to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts and hedging relationships that reference the London Interbank Offered Rate or another reference rate expected to be discontinued due to reference rate reform. These amendments are effective immediately and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. The Partnership is currently evaluating its contracts and the optional expedients provided by ASU 2020-04 and the impact the new standard will have on its consolidated financial statements and related disclosures.
3. Revenue Recognition
Disaggregation of Revenues
The following table presents revenues associated with contracts with customers for the periods presented:
Three Months Ended March 31,
2021 2020
(In thousands)
Service revenues
Crude oil, natural gas and NGL revenues $ 45,094 $ 53,977
Produced and flowback water revenues 22,969 31,862
Total service revenues 68,063 85,839
Product revenues
Crude oil, natural gas and NGL revenues 30,589 14,436
Freshwater revenues 1,721 6,352
Total product revenues 32,310 20,788
Total revenues $ 100,373 $ 106,627

Prior Period Performance Obligations
The Partnership records revenue when the performance obligations under the terms of its customer contracts are satisfied. The Partnership measures the satisfaction of its performance obligations using the output method based upon the volumes of crude oil, natural gas or water that flow through its systems. In certain cases, the Partnership is required to estimate these volumes during a reporting period and record any differences between the estimated volumes and actual volumes in the following reporting period. Such differences have historically not been significant. For the three months ended March 31, 2021 and 2020, revenues recognized related to performance obligations satisfied in prior reporting periods were not material.
Contract Balances
Contract balances are the result of timing differences between revenue recognition, billings and cash collections. Contract assets relate to revenue recognized for accrued deficiency fees associated with minimum volume commitments where the Partnership believes it is probable there will be a shortfall payment and that a significant reversal of revenue recognized will not occur once the related performance period is completed and the customer is billed. Contract liabilities relate to aid in construction payments received from customers, which are recognized as revenue over the expected period of future benefit. The Partnership does not recognize contract assets or contract liabilities under its customer contracts for which invoicing occurs once the Partnership's performance obligations have been satisfied and payment is unconditional. Contract balances are classified as current or long-term based on the timing of when the Partnership expects to receive cash for contract assets or recognize revenue for contract liabilities. The Partnership did not have any material contract asset balances as of March 31, 2021 or December 31, 2020.

2023 10,896
2024 11,089
2025 2,768
Total $ 54,792
The partially and wholly unsatisfied performance obligations presented in the table above are generally limited to customer contracts which have fixed pricing and fixed volume terms and conditions, which generally include customer contracts with minimum volume commitment payment obligations.
The Partnership has elected practical expedients, pursuant to Accounting Standards Codification 606, Revenue from Contracts with Customers, to exclude from the presentation of remaining performance obligations: (i) contracts with index-based pricing or variable volume attributes in which such variable consideration is allocated entirely to a wholly unsatisfied performance obligation or to a wholly unsatisfied promise to transfer a distinct service that forms part of a series of distinct services and (ii) contracts with an original expected duration of one year or less.
4. Transactions with Affiliates
Revenues. The Partnership generates the substantial majority of its revenues through fee-based contractual arrangements with wholly-owned subsidiaries of Oasis Petroleum for midstream services as described in Note 1 - Organization and Nature of Operations. In addition, the Partnership sells the residue gas and NGLs recovered from its gas processing plants attributable to its third-party natural gas purchase agreements to Oasis Petroleum to market and sell to non-affiliated purchasers.
Expenses. Oasis Petroleum provides substantial labor and overhead support to the Partnership pursuant to a services and secondment agreement. Oasis Petroleum performs centralized corporate, general and administrative services for the Partnership, such as legal, corporate recordkeeping, planning, budgeting, regulatory, accounting, billing, business development, treasury, insurance administration and claims processing, risk management, health, safety and environmental, information technology, human resources, investor relations, cash management and banking, payroll, internal audit, tax and engineering. Oasis Petroleum has also seconded to the Partnership certain of its employees to operate, construct, manage and maintain the Partnership's assets. The expenses of executive officers and non-executive employees of Oasis Petroleum are allocated to the Partnership based on the amount of time spent managing its business and operations. The Partnership reimburses Oasis Petroleum for direct and allocated general and administrative expenses incurred by Oasis Petroleum for the provision of these services.
The Partnership's general and administrative expenses includes $6.9 million and $7.6 million from affiliate transactions with Oasis Petroleum for the three months ended March 31, 2021 and 2020, respectively.
Simplification Transaction. On March 30, 2021, the Partnership consummated the transactions contemplated by the Contribution and Simplification Agreement (the 'Contribution and Simplification Agreement'), dated as of March 22, 2021, by and among the Partnership, OMS Holdings LLC ('OMS Holdings'), Oasis Midstream Services LLC ('OMS'), OMP GP LLC (the 'General Partner'), OMP Operating LLC ('OMP Operating'), OMP DevCo Holdings Corp, Beartooth DevCo LLC ('Beartooth DevCo'), Bobcat DevCo LLC ('Bobcat DevCo'), OMS Holdings Merger Sub, LLC, a wholly owned subsidiary of OMS Holdings ('GP Merger Sub'), and for limited purposes set forth therein, Oasis Petroleum.
Pursuant to the Contribution and Simplification Agreement, among other things, (a) Oasis Petroleum contributed to the Partnership its remaining limited liability company interests in Bobcat DevCo and Beartooth DevCo of 64.7% and 30.0%,

Table of Contents
respectively, in exchange for total consideration of $512.5 million composed of (x) a cash distribution of $231.5 million, sourced from the net proceeds of the offering of the Senior Notes (defined below) and (y) 12,949,644 common units representing limited partner interests in the Partnership, (b) the Partnership's incentive distribution rights ('IDRs') were cancelled and converted into 1,850,356 common units representing limited partner interests in the Partnership (the 'IDR Elimination' and such common units, the 'IDR Conversion Common Units'), and (c) the IDR Conversion Common Units were distributed on a pro-rata basis by the General Partner to the holders of its Class A Units and Class B Units, such that following such distribution, Oasis Petroleum, through its wholly-owned subsidiary OMS Holdings, is the sole member of the General Partner (the foregoing clauses (a), (b) and (c), the 'Simplification Transaction'). The Contribution and Simplification Agreement also implemented among other things, a right of first refusal in favor of the Partnership with respect to the midstream opportunities in the Painted Woods and City of Williston operating areas of Oasis Petroleum and the amendment and restatement of the (x) agreement of limited partnership of the Partnership and (y) limited liability company agreement of the General Partner to reflect the Simplification Transaction.
The effective date of the Simplification Transaction was January 1, 2021 and was accounted for on the closing date of March 30, 2021. As a result, net income was allocated to Oasis Petroleum's non-controlling interests in Bobcat DevCo and Beartooth DevCo until the closing date. The cash distribution to Oasis Petroleum of $231.5 million includes: (i) $229.0 million cash component of the purchase price, (ii) $10.1 million upward adjustment to the purchase price related to the expanded project dedication to OMP in South Nesson and (iii) $7.6 million downward adjustment to the purchase price related to activity between the effective date and the close date. At March 30, 2021, Oasis Petroleum's non-controlling interests in Bobcat DevCo and Beartooth DevCo were eliminated, and Oasis Petroleum no longer owns any of the limited liability company interests of Bobcat DevCo or Beartooth DevCo.

Revolving Credit Facility
The Partnership has a revolving credit facility among OMP Operating, as borrower, Wells Fargo Bank, N.A., as Administrative Agent (the 'Administrative Agent') and the lenders party thereto (as amended, the 'Revolving Credit Facility'). On March 22, 2021, the Partnership entered into the Fourth Amendment to the Revolving Credit Facility to, among other things, (i) provide for the occurrence of the transactions pursuant to the Simplification Transaction, (ii) amend the consolidated total leverage ratio financial covenant to no greater than 5.00 to 1.00, (iii) amend the consolidated senior secured leverage ratio to no greater than 3.00 to 1.00, (iv) amend the consolidated interest coverage ratio to no less than 2.50 to 1.00, (v) provide for the issuance of the Senior Notes (defined below), (vi) decrease the aggregate lender commitments to $450.0 million, (vii) increase pricing for credit and (viii) extend the maturity date from September 25, 2022 until at least September 30, 2024. In connection with the Fourth Amendment to the Revolving Credit Facility, the Partnership accelerated $1.1 million of unamortized deferred financing costs.
The applicable margin for borrowings under the Revolving Credit Facility is based on the Partnership's most recently tested consolidated total leverage ratio and varies from (a) in the case of Eurodollar Loans, 2.25% to 3.25%, and (b) in the case of ABR Loans or swingline loans, 1.25% to 2.25%. The unused portion of the Revolving Credit Facility is subject to a commitment fee ranging from 0.375% to 0.500%.
At March 31, 2021, the aggregate commitments under the Revolving Credit Facility were $450.0 million, and the Partnership had $234.0 million of borrowings outstanding and $5.5 million of outstanding letters of credit, resulting in an unused borrowing capacity of $210.5 million. For the three months ended March 31, 2021, the weighted average interest rate incurred on borrowings under the Revolving Credit Facility was 2.1%. At December 31, 2020, the Partnership had $450.0 million of borrowings outstanding under the Revolving Credit Facility and a de minimis outstanding letter of credit. The fair value of the Revolving Credit Facility approximates its carrying value since borrowings under the Revolving Credit Facility bear interest at variable rates, which are tied to current market rates.
The Partnership was in compliance with the covenants under the Revolving Credit Facility at March 31, 2021. The Revolving Credit Facility contains customary events of default, as well as cross-default provisions with other indebtedness of the Partnership and its restricted subsidiaries. If an event of default occurs and is continuing, the lenders may declare all amounts outstanding under the Revolving Credit Facility to be immediately due and payable. There are no cross-default provisions between the Revolving Credit Facility and Oasis Petroleum's revolving credit facility.
Senior Unsecured Notes
On March 30, 2021, the Partnership and OMP Finance Corp. ('OMP Finance' and together with the Partnership, the 'Issuers') issued in a private placement $450.0 million of 8.00% senior unsecured notes due April 1, 2029 (the 'Senior Notes'). The Senior Notes were issued at par and resulted in net proceeds, after deducting the underwriters' gross spread, of $442.1 million. The Partnership used the net proceeds from the Senior Notes to: (i) make a distribution to OMS of $231.5 million in connection with the Simplification Transaction, (ii) repay $204.0 million of outstanding principal borrowings and $0.5 million of accrued interest under the Revolving Credit Facility and (iii) pay approximately $6.1 million in fees and other expenses. The Partnership recorded deferred financing costs of $9.8 million in connection with the Senior Notes offering, which are being amortized over the term of the Senior Notes.
Interest on the Senior Notes is payable semi-annually on April 1 and October 1 of each year, commencing on October 1, 2021. The fair value of the Senior Notes, which are publicly traded among qualified institutional investors and represent a Level 1 measurement, was $460.1 million at March 31, 2021.
The Senior Notes are fully and unconditionally guaranteed on a senior unsecured basis by the Issuers, along with the Partnership's wholly-owned subsidiaries (the 'Guarantors'). The Senior Notes guarantees are joint and several obligations of the Guarantors. The Issuers and Guarantors do not have any significant restrictions on the ability to obtain funds from its subsidiaries by dividend or loan. In addition, there are no restrictions on the subsidiaries to transfer funds, and as such, there are no restricted net assets to disclose.
The indenture governing the Senior Notes contains certain covenants that, subject to certain exceptions and qualifications, among other things, limit the Partnership's ability and the ability of its restricted subsidiaries, including OMP Finance, to incur

or guarantee additional indebtedness or issue certain redeemable or preferred equity, make certain investments, declare or pay dividends or make distributions on equity interests or redeem, repurchase or retire equity interests or subordinated indebtedness, transfer or sell assets including equity of restricted subsidiaries, agree to payment restrictions affecting the Partnership's restricted subsidiaries, consolidate, merge, sell or otherwise dispose of all or substantially all of its assets, enter into transactions with affiliates, incur liens and designate certain of the Partnership's subsidiaries as unrestricted subsidiaries. In addition, the indenture governing the Senior Notes contains cross-default provisions with other indebtedness of the Partnership and its restricted subsidiaries. There are no cross-default provisions between the Senior Notes and other indebtedness of the Partnership and its restricted subsidiaries.
8. Inventory
Inventory consists primarily of spare parts and equipment related to the Partnership's midstream infrastructure. Inventory is stated at the lower of cost and net realizable value with cost determined on an average cost method. The Partnership assesses the carrying value of inventory and uses estimates and judgments when making any adjustments necessary to reduce the carrying value to net realizable value. The carrying value of the Partnership's inventory was $7.0 million at March 31, 2021 and December 31, 2020.
9. Commitments and Contingencies
The Partnership has various contractual obligations in the normal course of its operations. Included below is a description of the Partnership's various future commitments as of March 31, 2021. There have been no material changes to the Partnership's commitments and contingencies disclosed in its 2020 Annual Report.
Litigation.The Partnership is party to various legal and/or regulatory proceedings from time to time arising in the ordinary course of business. When the Partnership determines that a loss is probable of occurring and is reasonably estimable, the Partnership accrues an undiscounted liability for such contingencies based on its best estimate using information available at the time. The Partnership discloses contingencies where an adverse outcome may be material, or where in the judgment of management, the matter should otherwise be disclosed.

11. Earnings (Loss) Per Limited Partner Unit
Earnings (loss) per limited partner unit is computed by dividing the respective limited partners' interest in earnings (loss) attributable to the Partnership by the weighted average number of common and subordinated units outstanding. For periods prior to the conversion of subordinated units and IDR Elimination, the Partnership had more than one class of participating securities and used the two-class method when calculating earnings (loss) per limited partner unit. The classes of participating securities include common units, subordinated units and IDRs.
Diluted earnings (loss) per limited partner unit reflects the potential dilution that could occur if securities or agreements to issue common units, such as awards under the LTIP, were exercised, settled or converted into common units. When it is determined that potential common units should be included in diluted net income (loss) per limited partner unit calculation, the impact is reflected by applying the treasury stock method. There are no adjustments made to net income (loss) attributable to Oasis Midstream Partners LP in the calculation of diluted earnings (loss) per unit. For the three months ended March 31, 2021 and 2020, the diluted earnings (loss) per share calculation excludes the anti-dilutive effect of unvested restricted unit awards.
The following is a calculation of the basic and diluted weighted average units outstanding for the periods presented:

developments in the global economy as well as the public health crisis related to the COVID-19 virus and resulting demand and supply for crude oil and natural gas;
uncertainty regarding the length of time it will take for the U.S. and the rest of the world to slow the spread of the COVID-19 virus to the point where applicable authorities are comfortable easing current restrictions on various commercial and economic activities; such restrictions are designed to protect public health but also have the effect of significantly reducing demand for crude oil and natural gas;
uncertainty regarding the future actions of foreign oil producers and the related impacts such actions have on the balance between the supply of and demand for crude oil and natural gas and therefore the demand for midstream services;
uncertainty regarding the timing, pace and extent of an economic recovery in the U.S. and elsewhere, which in turn will likely affect demand for crude oil and natural gas and therefore the demand for the midstream services we provide and the commercial opportunities available to us;
an inability of Oasis Petroleum or our other customers to meet their operational and development plans on a timely basis or at all;
the execution of our business strategies;
the demand for and price of crude oil and natural gas, on an absolute basis and in comparison to the price of alternative and competing fuels;
the fees we charge, and the margins we realize, from our midstream services;
the cost of achieving organic growth in current and new markets;
our ability to make acquisitions of other midstream infrastructure assets or other assets that complement or diversify our operations;
our ability to make acquisitions of other assets on economically acceptable terms from Oasis Petroleum;
our inability to perform our obligations under our contracts, whether due to non-performance by third parties, including our customers or other counterparties, market constraints, third-party constraints, legal constraints (including governmental orders or guidance), or other factors;
the lack of asset and geographic diversification;
the suspension, reduction or termination of our commercial agreements with Oasis Petroleum;

Overview
We are a leading gathering and processing master limited partnership formed by our sponsor, Oasis Petroleum (Nasdaq: OAS), to own, develop, operate and acquire a diversified portfolio of midstream assets in North America. We offer full service midstream solutions to our customers covering their oil, gas and water needs. Our full scale of operations includes natural gas services (gathering, compression, processing and gas lift supply), crude oil services (gathering, terminaling and transportation) and water services (gathering and disposal of produced and flowback water and freshwater distribution). Our current assets are located in the heart of the oil-rich Williston and Permian Basins and are integral to the crude oil and natural gas operations of Oasis Petroleum. Our assets are also strategically positioned to capture volumes from other producers. We generate the substantial majority of our revenues through long-term, fixed-fee contracts with Oasis Petroleum pursuant to which we provide crude oil, natural gas and water-related midstream services. We expect to grow acquisitively through accretive, dropdown acquisitions, as well as organically as Oasis Petroleum develops its acreage. We also expect to grow by increasing services provided to third parties and acquiring midstream assets from third parties.
We have significant acreage dedications from Oasis Petroleum and commitments from third party producers in both the Williston and Permian Basins. In the Williston Basin, we divide our operations into two primary areas with developed midstream infrastructure. In Wild Basin, we provide natural gas services (gathering, compression, processing and gas lift supply), crude oil services (gathering, terminaling and transportation), and water services (gathering and disposal of produced and flowback water and freshwater distribution) to our customers. Outside of Wild Basin, we provide water services (gathering and disposal of produced and flowback water and freshwater distribution) to our customers. In the Permian Basin, we operate strategically located infrastructure where we provide crude oil services (gathering) and water services (gathering and disposal of produced and flowback water) to our customers, with connection points to key market hubs.
We conduct our business through our wholly-owned subsidiaries: Bighorn DevCo LLC ('Bighorn DevCo'), Bobcat DevCo LLC ('Bobcat DevCo'), Beartooth DevCo LLC ('Beartooth DevCo') and Panther DevCo LLC ('Panther DevCo' and collectively with Bighorn DevCo, Bobcat DevCo and Beartooth DevCo, the 'DevCos').

Table of Contents
We are party to long-term, fixed-fee contracts with Oasis Petroleum for natural gas services, crude oil services and water services. We are also party to a long-term transportation services agreement regulated by the Federal Energy Regulatory Commission governing the transportation of crude oil via pipeline from the Wild Basin area to Johnson's Corner. We generate the substantial majority of our revenues through these contracts, which minimizes our direct exposure to commodity prices. The amount of revenue we generate primarily depends on the volume of crude oil, natural gas and water for which we provide midstream services. While we have increased our customer diversification by providing midstream services to third parties, we are largely dependent on Oasis Petroleum as our most significant customer.
Recent Developments
Change in Board Chair
On April 14, 2021, Daniel E. Brown was elected to serve on the board of directors of OMP GP LLC (the 'General Partner'). On April 29, 2021, Mr. Brown was elected by the board of directors of the General Partner to serve as Board Chair. Mr. Brown replaces Douglas E.

Acquisition of Remaining Interests in Bobcat DevCo and Beartooth DevCo
On March 30, 2021, we consummated the transactions contemplated by the Contribution and Simplification Agreement (the 'Contribution and Simplification Agreement'), dated as of March 22, 2021, by and among the Partnership, OMS Holdings LLC ('OMS Holdings'), Oasis Midstream Services LLC ('OMS'), the General Partner, OMP Operating LLC ('OMP Operating'), OMP DevCo Holdings Corp, Beartooth DevCo LLC ('Beartooth DevCo'), Bobcat DevCo LLC ('Bobcat DevCo'), OMS Holdings Merger Sub, LLC, a wholly owned subsidiary of OMS Holdings ('GP Merger Sub'), and for limited purposes set forth therein, Oasis Petroleum.
Pursuant to the Contribution and Simplification Agreement, among other things, (a) Oasis Petroleum caused OMS to contribute to OMP Operating (i) its remaining 64.7% limited liability company interest in Bobcat DevCo and (ii) its remaining 30% limited liability company interest in Beartooth DevCo (the 'Contributed Assets'), and the Partnership paid to OMS Holdings consideration of $512.5 million (together with the IDR Conversion Common Units, the 'Total Consideration') composed of (x) a cash distribution of $231.5 million, sourced from the net proceeds of the offering of the Senior Notes (as defined below) and (y) 12,949,644 common units representing limited partner interests in the Partnership, (b) the Partnership and the General Partner caused the IDRs to be cancelled and converted into 1,850,356 common units representing limited partner interests in the Partnership (the 'IDR Elimination' and such common units, the 'IDR Conversion Common Units'), and (c) GP Merger Sub merged with and into the General Partner, with the General Partner surviving such merger (the 'GP Merger') and, in connection with the GP Merger, Class A Units and Class B Units representing membership interests in the General Partner were automatically converted into, and thereafter represented the right to receive, the IDR Conversion Common Units on a pro rata basis, and the IDR Conversion Common Units were distributed to the holders of such Class A Units and Class B Units, such that following the GP Merger, OMS Holdings is the sole member of the General Partner (the foregoing clauses (a), (b) and (c), the 'Simplification Transaction'). The Contribution and Simplification Agreement also implemented, among other things, a right of first refusal in favor of the Partnership with respect to midstream opportunities in the Painted Woods and City of Williston operating areas of Oasis Petroleum and the amendment and restatement of the (x) agreement of limited partnership of the Partnership and (y) limited liability company agreement of the General Partner to reflect the Simplification Transaction.
The effective date of the Simplification Transaction was January 1, 2021, and the closing date was March 30, 2021. Following the Simplification Transaction, Oasis Petroleum no longer owns any of the limited liability company interests of Bobcat DevCo or Beartooth DevCo.

Market Conditions and COVID-19
Market conditions have improved but remain uncertain as the worldwide response to COVID-19 continues to evolve. Federal, state and local public health and governmental authorities have begun implementation of programs to administer vaccines, and certain regions across the United States have begun to partially lift restrictions previously imposed to contain the spread of COVID-19. Global economic activity levels have improved as these restrictions have begun to be lifted, and energy demand has gradually increased. Despite moderate improvements in market conditions, uncertainties related to COVID-19 remain, including the impact of new virus strains, the risk of renewed restrictions and the uncertainty of successful administration of effective treatments and vaccines. In response to the current economic environment and impacts of COVID-19, we have adjusted our business to expected lower levels of activity and operate in a sustainable and cost-efficient manner.
In response to the outbreak of the COVID-19 pandemic in 2020, we adopted a work-from-home system for all office-based employees and deployed additional safety protocols at our operating sites in order to keep the field-based employees and contractors supporting our operations safe while continuing operations running without material disruption. In the first quarter of 2021, we began a phased return-to-office program, while continuing to follow enhanced safety standards and best practices, including enhanced daily cleaning in common spaces of office locations, required use of facial coverings in common spaces, restricting use of conference rooms and group gatherings, adherence to social distancing requirements and establishing training requirements and procedures.

Three months ended March 31, 2021 as compared to three months ended December 31, 2020
Total midstream revenues increased $9.8 million to $100.4 million during the three months ended March 31, 2021 as compared to the three months ended December 31, 2020. This increase was driven by a $5.7 million increase in service revenues and a $4.0 million increase in product sales.
The $5.7 million increase in service revenues was driven by a $7.4 million increase in crude oil and natural gas service revenues due to an increase in natural gas volumes from Oasis Petroleum in the Williston Basin, offset by a $1.6 million decrease in produced and flowback water service revenues due to a $1.1 million decrease in revenues from Oasis Petroleum primarily due to fewer volumes in the Williston Basin and a $0.5 million decrease in revenues from third parties.
The $4.0 million increase in product sales was driven by a $4.8 million increase in natural gas product sales to Oasis Petroleum driven by an increase in residue gas and NGL prices, partially offset by a $0.9 million decrease in freshwater product sales due to a decrease in freshwater deliveries to Oasis Petroleum for well completions.

Three months ended March 31, 2021 as compared to .three months ended March 31, 2020
Total midstream revenues decreased $6.3 million to $100.4 million during the three months ended March 31, 2021 as compared to the three months ended March 31, 2020. This decrease was driven by a a $17.8 million decrease in service revenues, partially offset by an $11.5 million increase in product sales.
The $17.8 million decrease in service revenues was driven by an $8.9 million decrease in produced and flowback water service revenues due to a $7.1 million decrease in revenues from Oasis Petroleum due to fewer volumes, and a $1.8 million decrease in revenues from third parties due to fewer volumes. In addition, there was an $8.9 million decrease in crude oil and natural gas service revenues primarily related to a decrease in crude oil and natural gas volumes in the Williston Basin.
The $11.5 million increase in product sales was driven by a $16.1 million increase in natural gas product sales to Oasis Petroleum driven by higher residue gas and NGL prices, partially offset by a $4.6 million decrease in freshwater product sales due to a decrease in freshwater deliveries to Oasis Petroleum for well completions.

Three months ended March 31, 2021 as compared to three months ended December 31, 2020
Costs of product sales. Costs of product sales increased $7.0 million to $22.8 million for the three months ended March 31, 2021 as compared to the three months ended December 31, 2020.The increase was primarily driven by a $7.2 million increase in natural gas costs of product sales due to an increase in natural gas purchase costs related to higher residue gas and NGL prices, partially offset by a $0.2 million decrease in freshwater costs of product sales related to lower activity.
Operating and maintenance. Operating and maintenance expenses decreased $0.8 million to $13.1 million for the three months ended March 31, 2021 as compared to the three months ended December 31, 2020. The decrease was primarily driven by a $0.5 million decrease in produced and flowback water operating and maintenance expenses related to lower activity, coupled with a $0.3 million decrease in crude oil and natural gas operating and maintenance expenses primarily related to lower crude oil expenses associated with reductions in contract labor costs.

Table of Contents
Depreciation and amortization. Depreciation and amortization expenses were $9.0 million for the three months ended March 31, 2021 and the three months ended December 31, 2020. No assets were placed into service during the three months ended March 31, 2021.
General and administrative ('G&A') expenses.G&A expenses decreased $0.3 million to $8.5 million for the three months ended March 31, 2021 as compared to the three months ended December 31, 2020. The decrease was primarily a result of a reduction in allocated charges from Oasis Petroleum for G&A services.
Interest expense, net of capitalized interest. Interest expense, net of capitalized interest, increased $1.5 million to $4.1 million for the three months ended March 31, 2021 as compared to the three months ended December 31, 2020. The increase was primarily due to the acceleration of $1.1 million of unamortized deferred financing costs in connection with the Fourth Amendment to the Revolving Credit Facility.
Three months ended March 31, 2021 as compared to three months ended March 31, 2020
Costs of product sales. Cost of product sales increased $14.3 million to $22.8 million for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020. The increase was primarily driven by a $16.4 million increase in natural gas costs of product sales due to an increase in natural gas purchase costs related to higher residue gas and NGL prices, partially offset by a $2.2 million decrease in freshwater costs of product sales related to lower activity.
Operating and maintenance. Operating and maintenance expenses decreased $3.7 million to $13.1 million for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020.The decrease was primarily driven by a $2.0 million decrease in produced and flowback water operating and maintenance expenses, a $1.4 million decrease in natural gas operating and maintenance expenses and a $0.3 million decrease in crude oil operating and maintenance expenses, each related to reductions in activity.
Impairment. No impairment loss was recorded for the three months ended March 31, 2021. We recorded an impairment loss of $101.8 million for the three months ended March 31, 2020 to adjust the carrying value of our property, plant and equipment to fair value due to lower forecasted throughput volumes.
Depreciation and amortization. Depreciation and amortization expenses decreased $1.2 million to $9.0 million for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020. The decrease was driven by a reduction in the carrying value of assets following impairment charges taken in the first quarter of 2020.
G&A expenses.G&A expenses remained flat at $8.5 million for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020.
Interest expense, net of capitalized interest. Interest expense, net of capitalized interest, decreased $26.2 million to $4.1 million for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020. The decrease was primarily due to an additional interest charge of $25.9 million recorded in the first quarter of 2020. In the fourth quarter of 2020, we received a waiver for such additional interest charge.
Liquidity and Capital Resources
Our primary sources of liquidity are cash flows generated from operations, borrowings under our Revolving Credit Facility and the issuance of the Senior Notes, as defined below. We believe cash generated from these sources will be sufficient to meet our short-term working capital needs, long-term capital expenditure requirements and quarterly cash distributions. We expect to fund future expansion capital expenditures and acquisitions primarily through a combination of borrowings under our Revolving Credit Facility and, if necessary, the issuance of additional equity or debt securities.
Our primary uses of cash have been for capital expenditures for our midstream infrastructure, the acquisition of Oasis Petroleum's remaining ownership interests in Bobcat DevCo and Beartooth DevCo, the acquisition of midstream infrastructure in the Permian Basin from Oasis Petroleum, distributions to our unitholders and payments associated with cash requirements for working capital. We expect our future cash requirements relating to working capital, maintenance capital expenditures and quarterly cash distributions to our unitholders will be funded from cash flows internally generated from our operations.
Revolving credit facility.At March 31, 2021, we had $450.0 million of commitments under the Revolving Credit Facility. The Revolving Credit Facility is available to fund working capital and to finance acquisitions and other capital expenditures and does not mature until at least September 30, 2024.
At March 31, 2021, we had $234.0 million of borrowings outstanding under the Revolving Credit Facility and $5.5 million of outstanding letters of credit, resulting in an unused borrowing capacity of $210.5 million. For three months ended March 31, 2021 and 2020, the weighted average interest rate incurred on borrowings under the Revolving Credit Facility was 2.1% and 3.6%, respectively.

Table of Contents
On March 22, 2021, we entered into the Fourth Amendment to the Revolving Credit Facility. See 'Item 1. - Financial Statements (Unaudited) - Note 7- Long-Term Debt' for more information.
Senior unsecured notes.On March 30, 2021, we issued $450.0 million of 8.00% senior unsecured notes due April 1, 2029 (the 'Senior Notes'). The Senior Notes were issued at par and resulted in net proceeds of $442.1 million. We used the net proceeds from the Senior Notes to: (i) make a distribution to OMS of $231.5 million in connection with the Simplification Transaction, (ii) repay $204.0 million of outstanding principal borrowings and $0.5 million of accrued interest under the Revolving Credit Facility and (iii) pay approximately $6.1 million in fees and other expenses. See 'Item 1. - Financial Statements (Unaudited) - Note 7- Long-Term Debt' for more information.
Cash flows
Our cash flows for the three months ended March 31, 2021 and 2020 are presented below:
Three Months Ended March 31,
2021 2020
(In thousands)
Net cash provided by operating activities $ 39,441 $ 61,665
Net cash used in investing activities (887) (31,811)
Net cash used in financing activities (36,543) (10,121)
Increase in cash and cash equivalents $ 2,011 $ 19,733
Cash flows provided by operating activities
Net cash provided by operating activities was $39.4 million and $61.7 million for the three months ended March 31, 2021 and 2020, respectively. The $22.2 million decrease in cash flows from operating activities for the three months ended March 31, 2021, as compared to 2020, was primarily due to net changes in working capital items, offset by higher net income after adjusting for non-cash items.
Working capital. Our working capital is driven by changes in accounts receivable and accounts payable and other factors, such as credit extended to, and the timing of collections from, our customers. As of March 31, 2021, we had a working capital balance of $52.7 million, and we had $217.7 million of liquidity available, including $7.2 million in cash and cash equivalents and $210.5 million in unused borrowing capacity on our Revolving Credit Facility.
We expect to have adequate liquidity to meet our future working capital requirements; however, extended disruptions in the financial markets and/or energy price volatility that adversely affect our business may have a material adverse effect on our financial position, results of operations or cash flows.
Cash flows used in investing activities
Net cash used in investing activities was $0.9 million and $31.8 million for the three months ended March 31, 2021 and 2020, respectively. The $30.9 million decrease in net cash used in investing activities for the three months ended March 31, 2021, as compared to 2020, was primarily attributable to capital spending in the first quarter of 2020 related to the construction of two additional compressor stations around Wild Basin, which were placed into service during the first quarter of 2020.
Cash flows used in financing activities
Net cash used in financing activities was $36.5 million for the three months ended March 31, 2021 and $10.1 million for the three months ended March 31, 2020. The $26.4 million increase in net cash used in financing activities was primarily attributable to the cash distribution of $231.5 million to Oasis Petroleum in connection with the Simplification Transaction and an increase in repayment of outstanding borrowings under the Revolving Credit Facility, partially offset by net cash proceeds associated with the issuance of Senior Notes and a reduction in distributions to Oasis Petroleum associated with their retained interests in Bobcat DevCo and Beartooth DevCo.

2021 Revised Capital Program.Our revised 2021 capital program, excluding acquisitions, will accommodate a capital expenditure level of approximately $53.0 million to $58.0 million, which was adjusted downward to reflect $10.1 million of capital expenditures which were settled in the purchase price of the Simplification Transaction. We expect to spend approximately 7% to 8% of EBITDA for maintenance capital expenditures, which is included in our total capital expenditure program.
We will continue to evaluate the level of capital spending throughout the year based on the following factors, among others:

pace of our customers' development;
operating and construction costs;
our ability to achieve material supplier price reductions;
indebtedness levels; and

Cash distributions
On May 3, 2021, the Board of Directors of the General Partner declared the quarterly distribution for the first quarter of 2021 of $0.55 per unit. This distribution will be payable on May 27, 2021 to unitholders of record as of May 17, 2021.
The board of directors of our General Partner may change our cash distribution policy at any time, and we do not have a legal or contractual obligation to pay cash distributions quarterly or on any other basis or at our minimum quarterly distribution rate.
Non-GAAP Financial Measures
Cash Interest, Adjusted EBITDA, Distributable Cash Flow and Free Cash Flow are supplemental non-GAAP financial measures that are used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies. These non-GAAP financial measures should not be considered in isolation or as a substitute for interest expense, net income (loss), operating income (loss), net cash provided by (used in) operating activities or any other measures prepared under GAAP. Because Cash Interest, Adjusted EBITDA, Distributable Cash Flow and Free Cash Flow exclude some but not all items that affect interest expense, net income and net cash provided by operating activities and may vary among companies, the amounts presented may not be comparable to similar metrics of other companies.
Cash Interest
We define Cash Interest as interest expense plus capitalized interest less amortization of deferred financing costs included in interest expense. Cash Interest is not a measure of interest expense as determined by GAAP. Management believes that the presentation of Cash Interest provides useful additional information to investors and analysts for assessing the interest charges incurred on our debt, excluding non-cash amortization, and our ability to maintain compliance with our debt covenants.
The following table presents a reconciliation of the GAAP financial measure of interest expense, net of capitalized interest, to the non-GAAP financial measure of Cash Interest for the periods presented:

Table of Contents
Adjusted EBITDA
We define Adjusted EBITDA as earnings before interest expense (net of capitalized interest), income taxes, depreciation, amortization, equity-based compensation expenses and other similar non-cash adjustments. We define Adjusted EBITDA attributable to Oasis Midstream Partners LP as Adjusted EBITDA less Adjusted EBITDA attributable to Oasis Petroleum's retained interests in two of our DevCos. Adjusted EBITDA should not be considered an alternative to net income, net cash provided by operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP. Management believes that the presentation of Adjusted EBITDA provides information useful to investors and analysts for assessing our results of operations, financial performance and our ability to generate cash from our business operations without regard to our financing methods or capital structure coupled with our ability to maintain compliance with our debt covenants. The GAAP measures most directly comparable to Adjusted EBITDA are net income and net cash provided by operating activities.
Distributable Cash Flow and Free Cash Flow
We define Distributable Cash Flow as Adjusted EBITDA attributable to Oasis Midstream Partners LP less Cash Interest and maintenance capital expenditures attributable to Oasis Midstream Partners LP. We define Free Cash Flow as Distributable Cash Flow less expansion capital expenditures attributable to Oasis Midstream Partners LP less distributions to our unitholders. Distributable Cash Flow and Free Cash Flow should not be considered an alternative to net income, net cash provided by operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP. Management believes that the presentation of Distributable Cash Flow and Free Cash Flow provides information useful to investors and analysts for assessing our results of operations, financial performance and our ability to generate cash from our business operations without regard to our financing methods or capital structure, coupled with our ability to make distributions to our unitholders. The GAAP measures most directly comparable to Distributable Cash Flow and Free Cash Flow are net income and net cash provided by operating activities.

Critical Accounting Policies and Estimates
There have been no material changes to our critical accounting policies and estimates from those disclosed in our 2020 Annual Report other than as disclosed in Note 2 to our unaudited condensed consolidated financial statements.
Item 3. - Quantitative and Qualitative Disclosures About Market Risk
The primary objective of the following information is to provide forward-looking quantitative and qualitative information about our potential exposure to market risk. The term 'market risk' refers to the risk of loss arising from adverse changes in commodity prices and interest rates. The disclosures are not meant to be precise indicators of expected future losses, but rather indicators of reasonably possible losses. This forward-looking information provides indicators of how we view and manage our ongoing market risk exposures.
27
Table of Contents
Concentration of customer credit risk. We are dependent on Oasis Petroleum as our most significant customer, and we expect to derive a substantial majority of our revenues from Oasis Petroleum for the foreseeable future. As a result, any event, whether in our dedicated areas or otherwise, that adversely affects Oasis Petroleum's production, drilling schedule, financial condition, leverage, market reputation, liquidity, results of operations or cash flows may adversely affect our revenues and cash available for distribution. Further, we are subject to the risk of non-payment or non-performance by Oasis Petroleum. We cannot predict the extent to which Oasis Petroleum's business would be impacted if conditions in the energy industry were to deteriorate, nor can we estimate the impact such conditions would have on Oasis Petroleum's ability to execute its drilling and development program or to perform under our agreements. Any material non-payment or non-performance by Oasis Petroleum could reduce our ability to make distributions to our unitholders. We did not experience any significant defaults on accounts receivable during the three months ended March 31, 2021.
Commodity price risk.We have limited direct exposure to risks associated with fluctuating commodity prices due to the nature of our business and our long-term, fixed-fee arrangements with Oasis Petroleum. However, to the extent that our future contractual arrangements with Oasis Petroleum or third parties do not provide for fixed-fee structures, we may become subject to commodity price risk. Additionally, as a substantial portion of our revenues are derived from Oasis Petroleum, we will be indirectly subject to risks associated with fluctuating commodity prices to the extent that lower commodity prices adversely affect Oasis Petroleum's production, drilling schedule, financial condition, leverage, market reputation, liquidity, results of operations or cash flows.
Interest rate risk.At March 31, 2021, we had outstanding $450.0 million of senior unsecured notes at a fixed cash interest rate of 8.00% per annum. At March 31, 2021 we had $234.0 million of borrowings outstanding under the Revolving Credit Facility. Borrowings under the Revolving Credit Facility bear interest at a rate per annum equal to the applicable margin (as described below) plus (i) with respect to Eurodollar Loans, the Adjusted LIBO Rate (as defined in the Revolving Credit Facility) or (ii) with respect to ABR Loans (as defined in the Revolving Credit Facility), the greatest of (a) the Prime Rate in effect on such day, (b) the Federal Funds Effective Rate in effect on such day plus 1/2 of 1.00% or (c) the Adjusted LIBO Rate for a one-month interest period on such day plus 1.00% (each as defined in the Revolving Credit Facility). The applicable margin for borrowings under the Revolving Credit Facility is based on the Partnership's most recently tested consolidated total leverage ratio and varies from (a) in the case of Eurodollar Loans, 2.25% to 3.25%, and (b) in the case of ABR Loans or swingline loans, 1.25% to 2.25%. The unused portion of the Revolving Credit Facility is subject to a commitment fee ranging from 0.375% to 0.500%.
At March 31, 2021, the outstanding borrowings under our Revolving Credit Facility bore interest at the London Interbank Offered Rate plus a 2.50% margin. We do not currently, but may in the future, utilize interest rate derivatives to reduce interest rate exposure in an attempt to reduce interest rate expense related to debt issued under our Revolving Credit Facility.

Evaluation of disclosure controls and procedures.As required by Rule 13a-15(b) under the Securities Exchange Act of 1934, as amended (the 'Exchange Act'), we have evaluated, under the supervision and with the participation of our management, including our Chief Executive Officer ('CEO'), our principal executive officer, and our Chief Financial Officer ('CFO'), our principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of March 31, 2021. Our disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed by us in the reports filed or submitted by us under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our CEO and CFO as appropriate, to allow timely decisions regarding required disclosure. Based on this evaluation, our CEO and CFO have concluded that our disclosure controls and procedures were effective at March 31, 2021.
Changes in internal control over financial reporting.There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) and Rule 15d-15(f) under the Exchange Act) that occurred during the three months ended March 31, 2021, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
