Weather-related impacts. InFebruary 2021 , theU.S. experienced winter storm Uri, bringing extreme cold temperatures, ice, and snow to the centralU.S. , includingTexas , and inMarch 2021 ,Colorado experienced a historic blizzard. Winter storm Uri adversely affected our volumes for approximately ten days and the blizzard inColorado likewise disrupted our assets in that state. We estimate the impact of these weather events to have reduced net income and Adjusted EBITDA (as defined under the caption Key Performance Metrics within this Item 2) for the quarter endedMarch 31, 2021 , by approximately$30 million due to lower volumes, the impact of commodity-prices, and higher operating expenses related to utilities. The estimated impact of the adverse winter weather on our operations and financial results may change and those changes may be material. Any additional inclement weather in the future, or other adverse conditions, including resolution of litigation and other legal disputes and the COVID-19 pandemic and resulting mitigation factors, may have an adverse impact on our operations and financial results. 38
--------------------------------------------------------------------------------
Table of Contents COVID-19. During 2020, the global outbreak of COVID-19 caused a sharp decline in the worldwide demand for oil, natural gas, and NGLs, which contributed significantly to commodity-price declines and oversupplied commodities markets. These market dynamics have had an adverse impact on producers that provide throughput into our systems, and we have experienced decreased throughput at many of our locations. Additionally, many of our employees have been and may continue to be subject to pandemic-related work-from-home requirements, which require us to take additional actions to ensure that the number of personnel accessing our network remotely does not lead to excessive cyber-security risk levels. Similarly, we are working continually to ensure operational changes that we have made to promote the health and safety of our personnel during this pandemic do not unduly disrupt intracompany communications and key business processes. We consider our risk-mitigation efforts adequate; however, the ultimate impact of the ongoing pandemic is unpredictable, with direct and indirect impacts to our business. WES continues to monitor the COVID-19 situation closely, and as state and federal governments issue additional guidance, we will update our own policies in response to ensure the safety and health of our workforce and communities. The federal government has provided guidance to states on how to safely return personnel to the workplace, which we are following as our workforce returns to WES locations. All WES facilities, including field locations, have been conducting enhanced routine cleaning and disinfecting of common areas and frequently touched surfaces using CDC- and EPA-approved products. Our return-to-work protocols include daily required application-based health self-assessments that must be completed prior to accessing WES work locations. Commodity purchase and sale agreements. EffectiveApril 1, 2020 , changes to marketing-contract terms with AESC terminated AESC's prior status as an agent of the Partnership for third-party sales and established AESC as a customer of the Partnership. Accordingly, we no longer recognize service revenues and/or product sales revenues and the equivalent cost of product expense for the marketing services performed by AESC. Year-over-year variances for the three months endedMarch 31, 2021 , include the following impacts related to this change (i) decrease of$45.9 million in Service revenues - fee based, (ii) decrease of$20.4 million in Product sales, and (iii) decrease of$66.3 million in Cost of product expense. These changes had no impact to Operating income (loss), Net income (loss), the balance sheets, cash flows, or any non-GAAP metric used to evaluate our operations (see Key Performance Metrics within this Item 2). See Note 6-Related-Party Transactions in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q. 39

OUTLOOK We expect our business to continue to be affected by the below-described key trends and uncertainties. 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 incorrect, our actual results may vary materially from expected results. Impact of crude-oil, natural-gas, and NGLs prices. Crude-oil, natural-gas, and NGLs prices can fluctuate significantly, and have done so over time. Commodity-price fluctuations affect the level of our customers' activities and our customers' allocations of capital within their own asset portfolios. During the first quarter of 2020, oil and natural-gas prices decreased significantly, driven by the expectation of increased supply and sharp declines in demand resulting from the worldwide macroeconomic downturn that followed the global outbreak of COVID-19. For example, NYMEX West Texas Intermediate crude-oil daily settlement prices ranged from a high of$63.27 per barrel inJanuary 2020 to a low below$20.00 per barrel inApril 2020 , with prices rebounding to$59.16 per barrel atMarch 31, 2021 . While the extent and duration of the recent commodity-price volatility cannot be predicted, potential impacts to our business include the following:
•We have exposure to increased credit risk to the extent any of our customers, including Occidental, is in financial distress. See Liquidity and Capital Resources-Credit risk within this Item 2 for additional information.
•An extended period of diminished earnings may restrict our ability to fully access our RCF, which contains various customary covenants, certain events of default, and a maximum consolidated leverage ratio based on Adjusted EBITDA (as defined in the covenant) related to the trailing twelve-month period. Further, any future waivers or amendments to the RCF also may trigger pricing increases for available credit. See Liquidity and Capital Resources-Debt and credit facilities within this Item 2 for additional information. •As ofMarch 31, 2021 , it is reasonably possible that future commodity-price declines, prolonged depression of commodity prices, changes to producers' drilling plans in response to lower prices, and potential producer bankruptcies could result in future long-lived asset impairments. To the extent producers continue with development plans in our areas of operation, we will continue to connect new wells or production facilities to our systems to maintain throughput on our systems and mitigate the impact of production declines. However, our success in connecting additional wells or production facilities is dependent on the activity levels of our customers. Additionally, we will continue to evaluate the crude-oil, NGLs, and natural-gas price environments and adjust our capital spending plans to reflect our customers' anticipated activity levels, while maintaining appropriate liquidity and financial flexibility. ACQUISITIONS AND DIVESTITURESFort Union and Bison facilities. InOctober 2020 , we (i) sold our 14.81% interest inFort Union , which was accounted for under the equity method of accounting, and (ii) entered into an option agreement to sell the Bison treating facility, located inNortheast Wyoming , to a third party, initially exercisable during the first quarter of 2021 and subsequently extended toMay 9, 2021 . During the second quarter of 2021, the third party exercised its option to purchase the Bison treating facility and it satisfied the held-for-sale criteria. The sale is expected to close in the second quarter of 2021. See Note 3-Acquisitions and Divestitures in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q for further information. 40

Natural-gas sales increased by$10.9 million compared to the three months endedMarch 31, 2020 , primarily due to increases of (i)$16.3 million at theWest Texas complex attributable to an increase in average prices, partially offset by decreased volumes sold, (ii)$4.4 million at the MGR assets attributable to an increase in average prices, and (iii)$1.4 million resulting from a change in accounting for the marketing contracts with AESC effectiveApril 1, 2020 (see Executive Summary-Commodity purchase and sale agreements within this Item 2). These increases were offset partially by a decrease of$10.5 million at theDJ Basin complex attributable to a decrease in volumes, partially offset by increased average prices.
NGLs sales
NGLs sales increased by$25.9 million compared to the three months endedDecember 31, 2020 , primarily due to increases of (i)$17.6 million at theWest Texas Complex attributable to an increase in average prices, partially offset by decreased volumes sold, (ii)$2.5 million at the Chipeta complex attributable to an increase in average prices, and (iii)$2.4 million at theDJ Basin complex attributable to an increase in average prices and volumes sold. NGLs sales increased by$3.3 million compared to the three months endedMarch 31, 2020 , primarily due to increases of (i)$19.1 million at theWest Texas complex attributable to an increase in average prices, partially offset by decreased volumes sold and (ii)$3.6 million at the Chipeta complex and$2.6 million at the Granger complex attributable to increases in average prices. These increases were offset partially by a decrease of$21.8 million resulting from a change in accounting for the marketing contracts with AESC effectiveApril 1, 2020 (see Executive Summary-Commodity purchase and sale agreements within this Item 2).

(1)Increases or decreases refer to the comparison of the three months endedMarch 31, 2021 , to the three months endedMarch 31, 2020 . (2)Average for period. Calculated as Adjusted gross margin for natural-gas assets, divided by total throughput (MMcf/d) attributable to WES for natural-gas assets. (3)Average for period. Calculated as Adjusted gross margin for crude-oil and NGLs assets, divided by total throughput (MBbls/d) attributable to WES for crude-oil and NGLs assets. (4)Average for period. Calculated as Adjusted gross margin for produced-water assets, divided by total throughput (MBbls/d) attributable to WES for produced-water assets. Adjusted gross margin. We define Adjusted gross margin attributable toWestern Midstream Partners, LP ("Adjusted gross margin") as total revenues and other (less reimbursements for electricity-related expenses recorded as revenue), less cost of product, plus distributions from equity investments, and excluding the noncontrolling interest owners' proportionate share of revenues and cost of product. We believe Adjusted gross margin is an important performance measure of our operations' profitability and performance as compared to other companies in the midstream industry. Cost of product expenses include (i) costs associated with the purchase of natural gas and NGLs pursuant to our percent-of-proceeds, percent-of-product, and keep-whole contracts, (ii) costs associated with the valuation of gas imbalances, and (iii) costs associated with our obligations under certain contracts to redeliver a volume of natural gas to shippers, which is thermally equivalent to condensate retained by us and sold to third parties. To facilitate investor and industry analyst comparisons between us and our peers, we also disclose per-Mcf Adjusted gross margin for natural-gas assets, per-Bbl Adjusted gross margin for crude-oil and NGLs assets, and per-Bbl Adjusted gross margin for produced-water assets. Adjusted gross margin decreased by$33.8 million compared to the three months endedDecember 31, 2020 , primarily due to (i) decreased throughput and a lower average fee resulting from a cost-of-service rate redetermination effectiveJanuary 1, 2021 , at the DBM water systems, (ii) a decrease in distributions fromWhitethorn LLC and Cactus II, (iii) an annual cost-of-service rate adjustment at theSpringfield system that increased revenues in the fourth quarter of 2020, and (iv) decreased throughput at the DBM oil system. These decreases were partially offset by an increase at theDJ Basin oil system due to an annual cost-of-service rate adjustment made during the fourth quarter of 2020. Adjusted gross margin decreased by$86.7 million compared to the three months endedMarch 31, 2020 , primarily due to (i) decreased throughput at theWest Texas complex andDJ Basin oil system, (ii) a lower average gathering fee and decreased throughput at theDJ Basin complex, (iii) decreased throughput and the effect of the straight-line treatment of lease revenue under the operating and maintenance agreement with Occidental at the DBM oil system, and (iv) decreased throughput and a lower average fee resulting from a cost-of-service rate redetermination effectiveJanuary 1, 2021 at the DBM water systems. Per-Mcf Adjusted gross margin for natural-gas assets increased by$0.03 compared to the three months endedMarch 31, 2020 , primarily due to a higher cost-of-service rate effectiveJanuary 1, 2021 , at theWest Texas complex, partially offset by decreased throughput at theDJ Basin complex, which has a higher-than-average per-Mcf margin as compared to our other natural-gas assets. 50
--------------------------------------------------------------------------------
Table of Contents Per-Bbl Adjusted gross margin for crude-oil and NGLs assets decreased by$0.24 compared to the three months endedDecember 31, 2020 , primarily due to (i) an annual cost-of-service rate adjustment at theSpringfield system that increased revenues in the fourth quarter of 2020 and (ii) a decrease in distributions from Cactus II. These decreases were partially offset by an annual cost-of-service rate adjustment made during the fourth quarter of 2020 and increased throughput at theDJ Basin oil system. Per-Bbl Adjusted gross margin for crude-oil and NGLs assets increased by$0.03 compared to the three months endedMarch 31, 2020 , primarily due to a higher cost-of-service rate effectiveJanuary 1, 2021 , at theDJ Basin oil system, partially offset by (i) decreased throughput and the effect of the straight-line treatment of lease revenue under the operating and maintenance agreement with Occidental at the DBM oil system, which has a higher-than-average per-Bbl margin as compared to our other crude-oil and NGLs assets and (ii) a decrease in distributions from Cactus II. Per-Bbl Adjusted gross margin for produced-water assets decreased by$0.06 and$0.05 compared to the three months endedDecember 31, 2020 , andMarch 31, 2020 , respectively, primarily due to a lower average fee resulting from a cost-of-service rate redetermination effectiveJanuary 1, 2021 . Adjusted EBITDA. We define Adjusted EBITDA attributable toWestern Midstream Partners, LP ("Adjusted EBITDA") as net income (loss), plus (i) distributions from equity investments, (ii) non-cash equity-based compensation expense, (iii) interest expense, (iv) income tax expense, (v) depreciation and amortization, (vi) impairments, and (vii) other expense (including lower of cost or market inventory adjustments recorded in cost of product), less (i) gain (loss) on divestiture and other, net, (ii) gain (loss) on early extinguishment of debt, (iii) income from equity investments, (iv) interest income, (v) income tax benefit, (vi) other income, and (vii) the noncontrolling interest owners' proportionate share of revenues and expenses. We believe the presentation of Adjusted EBITDA provides information useful to investors in assessing our financial condition and results of operations and that Adjusted EBITDA is a widely accepted financial indicator of a company's ability to incur and service debt, fund capital expenditures, and make distributions. Adjusted EBITDA is a supplemental financial measure that management and external users of our consolidated financial statements, such as industry analysts, investors, commercial banks, and rating agencies, use, among other measures, to assess the following: •our operating performance as compared to other publicly traded partnerships in the midstream industry, without regard to financing methods, capital structure, or historical cost basis;
•the ability of our assets to generate cash flow to make distributions; and
•the viability of acquisitions and capital expenditures and the returns on investment of various investment opportunities.
Adjusted EBITDA decreased by$40.9 million compared to the three months endedDecember 31, 2020 , primarily due to (i) a$54.5 million increase in cost of product (net of lower of cost or market inventory adjustments), (ii) an$8.0 million decrease in distributions from equity investments, (iii)$7.0 million increase in general and administrative expenses excluding non-cash equity-based compensation expense, and (iv)$3.3 million increase in property taxes. These amounts were offset partially by (i) a$27.5 million increase in total revenues and other and (ii) a$3.9 million decrease in operation and maintenance expenses. Adjusted EBITDA decreased by$70.5 million compared to the three months endedMarch 31, 2020 , primarily due to (i) a$99.3 million decrease in total revenues and other, (ii) a$4.7 million decrease in distributions from equity investments, and (iii) a$3.2 million increase in general and administrative expenses excluding non-cash equity-based compensation expense. These amounts were offset partially by (i) an$18.9 million decrease in operation and maintenance expenses, (ii) a$14.1 million decrease in cost of product (net of lower of cost or market inventory adjustments), and (iii) a$4.1 million decrease in property taxes. The above-described variances in cost of product and total revenues and other include the impacts resulting from a change in accounting for the marketing contracts with AESC effectiveApril 1, 2020 , which had no net impact on Adjusted EBITDA (see Executive Summary-Commodity purchase and sale agreements within this Item 2). 51
--------------------------------------------------------------------------------
Table of Contents Free cash flow. We define "Free cash flow" as net cash provided by operating activities less total capital expenditures and contributions to equity investments, plus distributions from equity investments in excess of cumulative earnings. Management considers Free cash flow an appropriate metric for assessing capital discipline, cost efficiency, and balance-sheet strength. Although Free cash flow is the metric used to assess WES's ability to make distributions to unitholders, this measure should not be viewed as indicative of the actual amount of cash that is available for distributions or planned for distributions for a given period. Instead, Free cash flow should be considered indicative of the amount of cash that is available for distributions, debt repayments, and other general partnership purposes. Free cash flow decreased by$250.9 million compared to the three months endedDecember 31, 2020 , primarily due to (i) a decrease of$244.0 million in net cash provided by operating activities and (ii) an increase of$9.0 million in capital expenditures. Free cash flow decreased by$0.8 million compared to the three months endedMarch 31, 2020 , primarily due to a decrease of$131.8 million in net cash provided by operating activities, partially offset by (i) a decrease of$113.0 million in capital expenditures, (ii) a decrease of$10.9 million in contributions to equity investments, and (iii) a$7.1 million increase in distributions from equity investments in excess of cumulative earnings. See Capital Expenditures and Historical Cash Flow within this Item 2 for further information. 52

Table of Contents Reconciliation of non-GAAP financial measures. Adjusted gross margin, Adjusted EBITDA, and Free cash flow are not defined in GAAP. The GAAP measure used by us that is most directly comparable to Adjusted gross margin is operating income (loss). Net income (loss) and net cash provided by operating activities are the GAAP measures used by us that are most directly comparable to Adjusted EBITDA. The GAAP measure used by us that is most directly comparable to Free cash flow is net cash provided by operating activities. Our non-GAAP financial measures of Adjusted gross margin, Adjusted EBITDA, and Free cash flow should not be considered as alternatives to the GAAP measures of operating income (loss), net income (loss), net cash provided by operating activities, or any other measure of financial performance presented in accordance with GAAP. Adjusted gross margin, Adjusted EBITDA, and Free cash flow have important limitations as analytical tools because they exclude some, but not all, items that affect operating income (loss), net income (loss), and net cash provided by operating activities. Adjusted gross margin, Adjusted EBITDA, and Free cash flow should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP. Our definitions of Adjusted gross margin, Adjusted EBITDA, and Free cash flow may not be comparable to similarly titled measures of other companies in our industry, thereby diminishing their utility as comparative measures. Management compensates for the limitations of Adjusted gross margin, Adjusted EBITDA, and Free cash flow as analytical tools by reviewing the comparable GAAP measures, understanding the differences between Adjusted gross margin, Adjusted EBITDA, and Free cash flow compared to (as applicable) operating income (loss), net income (loss), and net cash provided by operating activities, and incorporating this knowledge into its decision-making processes. We believe that investors benefit from having access to the same financial measures that our management considers in evaluating our operating results. The following tables present (i) a reconciliation of the GAAP financial measure of operating income (loss) to the non-GAAP financial measure of Adjusted gross margin, (ii) a reconciliation of the GAAP financial measures of net income (loss) and net cash provided by operating activities to the non-GAAP financial measure of Adjusted EBITDA, and (iii) a reconciliation of the GAAP financial measure of net cash provided by operating activities to the non-GAAP financial measure of Free cash flow: Three Months Ended December 31, thousands March 31, 2021 2020 March 31, 2020

Table of Contents
LIQUIDITY AND CAPITAL RESOURCES Our primary cash uses include quarterly distributions, debt service, capital expenditures, customary operating expenses, and distributions to our noncontrolling interest owners. Our sources of liquidity as ofMarch 31, 2021 , included cash and cash equivalents, cash flows generated from operations, available borrowing capacity under the RCF, and potential issuances of additional equity or debt securities. We believe that cash flows generated from these sources will be sufficient to satisfy our short-term working capital requirements and long-term capital-expenditure requirements. The amount of future distributions to unitholders will depend on our results of operations, financial condition, capital requirements, and other factors, and will be determined by the Board of Directors on a quarterly basis. We may rely on external financing sources, including equity and debt issuances, to fund capital expenditures and future acquisitions. However, we also may use operating cash flows to fund capital expenditures or acquisitions, which could result in borrowings under the RCF to pay distributions or to fund other short-term working capital requirements. Under our partnership agreement, we distribute all of our available cash (beyond proper reserves as defined in our partnership agreement) within 55 days following each quarter's end. Our cash flow and resulting ability to make cash distributions are dependent on our ability to generate cash flow from operations. Generally, our available cash is our cash on hand at the end of a quarter after the payment of our expenses and the establishment of cash reserves and cash on hand resulting from working capital borrowings made after the end of the quarter. The general partner establishes cash reserves to provide for the proper conduct of our business, including (i) reserves to fund future capital expenditures, (ii) to comply with applicable laws, debt instruments, or other agreements, or (iii) to provide funds for unitholder distributions for any one or more of the next four quarters. We have made cash distributions to our unitholders each quarter since our initial public offering in 2012. The Board of Directors declared a cash distribution to unitholders for the first quarter of 2021 of$0.31500 per unit, or$133.0 million in the aggregate. The cash distribution is payable onMay 14, 2021 , to our unitholders of record at the close of business onApril 30, 2021 . InNovember 2020 , we announced a buyback program of up to$250.0 million of our common units throughDecember 31, 2021 . The common units may be purchased from time to time in the open market at prevailing market prices or in privately negotiated transactions. The timing and amount of purchases under the program will be determined based on ongoing assessments of capital needs, our financial performance, the market price of the common units, and other factors, including organic growth and acquisition opportunities and general market conditions. The program does not obligate us to purchase any specific dollar amount or number of units and may be suspended or discontinued at any time. During the quarter endedMarch 31, 2021 , we repurchased 1,115,808 common units on the open market for an aggregate purchase price of$16.2 million . We canceled the units immediately upon receipt. As ofMarch 31, 2021 , we had an authorized amount of$201.2 million remaining under the Purchase Program. Management continuously monitors our leverage position and coordinates our capital expenditures and quarterly distributions with expected cash inflows and projected debt service requirements. We will continue to evaluate funding alternatives, including additional borrowings and the issuance of debt or equity securities, to secure funds as needed or to refinance maturing debt balances with longer-term debt issuances. Our ability to generate cash flows is subject to a number of factors, some of which are beyond our control. Read Risk Factors under Part II, Item 1A of this Form 10-Q. Working capital. As ofMarch 31, 2021 , we had a$120.9 million working capital surplus, which we define as the amount by which current assets exceed current liabilities. Working capital is an indication of liquidity and potential needs for short-term funding. Working capital requirements are 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, and the level and timing of our spending for acquisitions, maintenance, and other capital activities. As ofMarch 31, 2021 , there was$2.0 billion available for borrowing under the RCF. See Note 10-Selected Components of Working Capital and Note 11-Debt and Interest Expense in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q. 56
--------------------------------------------------------------------------------
Table of Contents Capital expenditures. Our business is capital intensive, requiring significant investment to maintain and improve existing facilities or to develop new midstream infrastructure. Capital expenditures includes maintenance capital expenditures, which include those expenditures required to maintain existing operating capacity and service capability of our assets, such as to replace system components and equipment that have been subject to significant use over time, become obsolete, or reached the end of their useful lives, to remain in compliance with regulatory or legal requirements, or to complete additional well connections to maintain existing system throughput and related cash flows; and expansion capital expenditures, which include expenditures to construct new midstream infrastructure and expenditures incurred to extend the useful lives of our assets, reduce costs, increase revenues, or increase system throughput or capacity from current levels, including well connections that increase existing system throughput. Capital expenditures in the consolidated statements of cash flows reflect capital expenditures on a cash basis, when payments are made. Capital incurred is presented on an accrual basis. Acquisitions and capital expenditures as presented in the consolidated statements of cash flows and capital incurred were as follows: Three Months Ended March 31, thousands 2021 2020 Acquisitions (1)$ 2,000 $ - Capital expenditures (2) 59,783 172,816 Capital incurred (2) 59,565 151,714

Capital expenditures decreased by$113.0 million for the three months endedMarch 31, 2021 , primarily due to decreases of (i)$56.2 million at theWest Texas complex primarily attributable to decreases in pipeline and well connection projects, (ii)$21.4 million at theDJ Basin complex primarily related to the completion of Latham Train II that commenced operations in the first quarter of 2020 and decreases in pipeline, well connection, and compression projects, (iii)$18.2 million at the DBM water systems primarily due to reduced construction of additional water-disposal facilities and gathering projects, and (iv)$16.5 million at the DBM oil system primarily related to the completion of the Loving ROTF Trains III and IV that commenced operations during the first and third quarters of 2020, respectively, and decreases in pipeline and well connection projects. 57

Table of Contents Debt and credit facilities. As ofMarch 31, 2021 , the carrying value of outstanding debt was$7.4 billion . See Note 11-Debt and Interest Expense in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q. WES Operating Senior Notes. Inmid-January 2020 , WES Operating issued the Fixed-Rate 3.100% Senior Notes due 2025, 4.050% Senior Notes due 2030, and 5.250% Senior Notes due 2050 and the Floating-Rate Senior Notes due 2023. Including the effects of the issuance prices, underwriting discounts, and interest-rate adjustments, the effective interest rates of the Senior Notes due 2025, 2030, and 2050, were 4.542%, 5.424%, and 6.629%, respectively, atMarch 31, 2021 . The interest rate on the Floating-Rate Senior Notes was 2.33% atMarch 31, 2021 . The effective interest rate of these notes is subject to adjustment from time to time due to a change in credit rating. During the first quarter of 2021, WES Operating redeemed the total principal amount outstanding of the 5.375% Senior Notes due 2021 at par value, pursuant to the optional redemption terms in WES Operating's indenture. AtMarch 31, 2021 , WES Operating was in compliance with all covenants under the relevant governing indentures. We may, from time to time, seek to retire, rearrange, or amend some or all of our outstanding debt or debt agreements through cash purchases, exchanges, open-market repurchases, privately negotiated transactions, tender offers, or otherwise. Such transactions, if any, will depend on prevailing market conditions, our liquidity position and requirements, contractual restrictions, and other factors. The amounts involved may be material. Revolving credit facility. WES Operating's$2.0 billion senior unsecured revolving credit facility is expandable to a maximum of$2.5 billion , and matures inFebruary 2025 for each extending lender. The non-extending lender's commitments mature inFebruary 2024 and represent$100.0 million out of$2.0 billion of total commitments from all lenders. As ofMarch 31, 2021 , there were no outstanding borrowings and$5.1 million of outstanding letters of credit, resulting in$2.0 billion of available borrowing capacity under the RCF. AtMarch 31, 2021 , the interest rate on any outstanding RCF borrowings was 1.61% and the facility-fee rate was 0.25%. AtMarch 31, 2021 , WES Operating was in compliance with all covenants under the RCF. The RCF contains certain covenants that limit, among other things, WES Operating's ability, and that of certain of its subsidiaries, to incur additional indebtedness, grant certain liens, merge, consolidate, or allow any material change in the character of its business, enter into certain related-party transactions and use proceeds other than for partnership purposes. The RCF also contains various customary covenants, certain events of default, and a maximum consolidated leverage ratio as of the end of each fiscal quarter (which is defined as the ratio of consolidated indebtedness as of the last day of a fiscal quarter to Consolidated EBITDA for the most-recent four-consecutive fiscal quarters ending on such day) of 5.0 to 1.0, or a consolidated leverage ratio of 5.5 to 1.0 with respect to quarters ending in the 270-day period immediately following certain acquisitions. As a result of certain covenants contained in the RCF, our capacity to borrow under the RCF may be limited. Finance lease liabilities. During the first quarter of 2020, WES entered into finance leases with third parties for equipment and vehicles extending through 2029. As ofMarch 31, 2021 , we have future finance-lease payments of$6.3 million for the remainder of 2021 and a total of$28.2 million in years thereafter. 60
--------------------------------------------------------------------------------
Table of Contents Credit risk. We bear credit risk through exposure to non-payment or non-performance by our counterparties, including Occidental, financial institutions, customers, and other parties. Generally, non-payment or non-performance results from a customer's inability to satisfy payables to us for services rendered, minimum-volume-commitment deficiency payments owed, or volumes owed pursuant to gas-imbalance agreements. We examine and monitor the creditworthiness of customers and may establish credit limits for customers. A substantial portion of our throughput is sourced from producers, including Occidental, that recently received credit-rating downgrades. We are subject to the risk of non-payment or late payment by producers for gathering, processing, transportation, and disposal fees. Additionally, we continue to evaluate counterparty credit risk and, in certain circumstances, are exercising our rights to request adequate assurance. We expect our exposure to the concentrated risk of non-payment or non-performance to continue for as long as our commercial relationships with Occidental generate a significant portion of our revenues. While Occidental is our contracting counterparty, gathering and processing arrangements with affiliates of Occidental on most of our systems include not just Occidental-produced volumes, but also, in some instances, the volumes of other working-interest owners of Occidental who rely on our facilities and infrastructure to bring their volumes to market. We also are party to agreements with Occidental under which Occidental is required to indemnify us for certain environmental claims, losses arising from rights-of-way claims, failures to obtain required consents or governmental permits, and income taxes with respect to the assets previously acquired fromAnadarko . See Note 6-Related-Party Transactions in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q. Our ability to make cash distributions to our unitholders may be adversely impacted if Occidental becomes unable to perform under the terms of gathering, processing, transportation, and disposal agreements; the contribution agreements; or the Services Agreement.
