DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION Basis of presentation. The consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and include the accounts of the Partnership and entities in which it holds a controlling financial interest, including WES Operating, WES Operating GP, proportionately consolidated interests, and equity investments (see table below). All significant intercompany transactions have been eliminated. The following table outlines the ownership interests and the accounting method of consolidation used in the consolidated financial statements for entities not wholly owned (see Note 6) : Percentage Interest Full consolidation Chipeta (1) 75.00 % Proportionate consolidation (2) Springfield system 50.10 % Marcellus Interest systems 33.75 % Equity investments (3) Mi Vida JV LLC (“Mi Vida”) 50.00 % Front Range Pipeline LLC (“FRP”) 33.33 % Red Bluff Express Pipeline, LLC (“Red Bluff Express”) 30.00 % Enterprise EF78 LLC (“Mont Belvieu JV”) 25.00 % Rendezvous Gas Services, LLC (“Rendezvous”) 22.00 % Texas Express Pipeline LLC (“TEP”) 20.00 % Texas Express Gathering LLC (“TEG”) 20.00 % Whitethorn Pipeline Company LLC (“Whitethorn LLC”) 20.00 % Saddlehorn Pipeline Company, LLC (“Saddlehorn”) 20.00 % Panola Pipeline Company, LLC (“Panola”) 15.00 % White Cliffs Pipeline, LLC (“White Cliffs”) 10.00 % _________________________________________________________________________________________ (1) The 25 % third - party interest in Chipeta Processing LLC (“Chipeta”) is reflected within noncontrolling interests in the consolidated financial statements. See Noncontrolling interests below. (2) The Partnership proportionately consolidates its associated share of the assets, liabilities, revenues, and expenses attributable to these assets. (3) Investments in non - controlled entities over which the Partnership exercises significant influence are accounted for under the equity method of accounting. “Equity - investment throughput” refers to the Partnership’s share of average throughput for these investments. Certain information and note disclosures commonly included in annual financial statements have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, the accompanying consolidated financial statements and notes should be read in conjunction with the Partnership’s 2022 Form 10-K, as filed with the SEC on February 22, 2023. Management believes that the disclosures made are adequate to make the information not misleading. The consolidated financial results of WES Operating are included in the Partnership’s consolidated financial statements. Throughout these notes to consolidated financial statements, and to the extent material, any differences between the consolidated financial results of the Partnership and WES Operating are discussed separately. The Partnership’s consolidated financial statements differ from those of WES Operating primarily as a result of (i) the presentation of noncontrolling interest ownership (see Noncontrolling interests below), (ii) the elimination of WES Operating GP’s investment in WES Operating with WES Operating GP’s underlying capital account, (iii) the general and administrative expenses incurred by the Partnership, which are separate from, and in addition to, those incurred by WES Operating, (iv) the inclusion of the impact of Partnership equity balances and Partnership distributions, and (v) transactions between the Partnership and WES Operating that eliminate upon consolidation. 15 Table of Contents WESTERN MIDSTREAM PARTNERS, LP AND WESTERN MIDSTREAM OPERATING, LP NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 1.

The Partnership’s assets include assets owned and ownership interests accounted for by the Partnership under the equity method of accounting, through its 98.0 % partnership interest in WES Operating, as of June 30, 2023 (see Note 6 ). The Partnership also owns and controls the entire non - economic general partner interest in WES Operating GP, and the Partnership’s general partner is owned by Occidental. Use of estimates. In preparing financial statements in accordance with GAAP, management makes informed judgments and estimates that affect the reported amounts of assets, liabilities, revenues, and expenses. Management evaluates its estimates and related assumptions regularly, using historical experience and other reasonable methods. Changes in facts and circumstances or additional information may result in revised estimates, and actual results may differ from these estimates. Effects on the business, financial condition, and results of operations resulting from revisions to estimates are recognized when the facts that give rise to the revisions become known. The information included herein reflects all normal recurring adjustments which are, in the opinion of management, necessary for a fair presentation of the consolidated financial statements. Noncontrolling interests. The Partnership’s noncontrolling interests in the consolidated financial statements consist of (i) the 25 % third - party interest in Chipeta and (ii) the 2.0 % limited partner interest in WES Operating owned by an Occidental subsidiary. WES Operating’s noncontrolling interest in the consolidated financial statements consists of the 25 % third - party interest in Chipeta. See Note 4. Segments.

Working capital borrowings generally include borrowings made under a credit facility or similar financing arrangement and are intended to be repaid or refinanced within 12 months. In all cases, working capital borrowings are used solely for working capital purposes or to fund unitholder distributions. The Board of Directors of the general partner (the “Board”) declared the following cash distributions to the Partnership’s unitholders for the periods presented: thousands except per-unit amounts Quarters Ended Total Quarterly Per-unit Distribution Total Quarterly Cash Distribution Distribution Date Record Date 2022 March 31 $ 0.500 $ 206,197 May 13, 2022 May 2, 2022 June 30 0.500 197,744 August 12, 2022 August 1, 2022 September 30 0.500 197,065 November 14, 2022 October 31, 2022 December 31 0.500 196,569 February 13, 2023 February 1, 2023 2023 March 31 (1) $ 0.856 $ 336,987 May 15, 2023 May 1, 2023 June 30 0.5625 221,442 August 14, 2023 July 31, 2023 _________________________________________________________________________________________ (1) Includes the regular quarterly distribution of $ 0.500 per unit, or $ 196.8 million, as well as the Enhanced Distribution of $ 0.356 per unit discussed below. To facilitate the distribution of available cash, during 2022 the Partnership adopted a financial policy that provided for an additional distribution (“Enhanced Distribution”) to be paid in conjunction with the regular first-quarter distribution of the following year (beginning in 2023), in a target amount equal to Free cash flow generated in the prior year after subtracting Free cash flow used for the prior year’s debt repayments, regular-quarter distributions, and unit repurchases. This Enhanced Distribution is subject to Board discretion, the establishment of cash reserves for the proper conduct of the Partnership’s business and is also contingent on the attainment of prior year-end net leverage thresholds (the ratio of total principal debt outstanding less total cash on hand as of the end of such period, as compared to trailing-twelve-months Adjusted EBITDA), after taking the Enhanced Distribution for such prior year into effect. Free cash flow and Adjusted EBITDA are defined under the caption Reconciliation of Non-GAAP Financial Measures within Part I, Item 2 of this Form 10-Q. In April 2023, the Board approved an Enhanced Distribution of $ 0.356 per unit, or $ 140.1 million, related to the Partnership’s 2022 performance, which was paid in conjunction with the regular first-quarter 2023 distribution on May 15, 2023. 19 Table of Contents WESTERN MIDSTREAM PARTNERS, LP AND WESTERN MIDSTREAM OPERATING, LP NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 3.

EQUITY AND PARTNERS’ CAPITAL Holdings of Partnership equity. The Partnership’s common units are listed on the New York Stock Exchange under the ticker symbol “WES.” As of June 30, 2023, Occidental held 190,281,578 common units, representing a 48.3 % limited partner interest in the Partnership, and through its ownership of the general partner, Occidental indirectly held 9,060,641 general partner units, representing a 2.3 % general partner interest in the Partnership. The public held 194,332,356 common units, representing a 49.4 % limited partner interest in the Partnership. Partnership equity repurchases. In 2022, the Board authorized the Partnership to buy back up to $ 1.25 billion of the Partnership’s common units through December 31, 2024 (the “$1.25 billion Purchase Program”). The common units may be purchased from time to time in the open market at prevailing market prices or in privately negotiated transactions. During the six months ended June 30, 2023, the Partnership repurchased 287,322 common units for an aggregate purchase price of $ 7.1 million. During the six months ended June 30, 2022, the Partnership repurchased 3,314,562 common units on the open market for an aggregate purchase price of $ 79.2 million. The units were canceled immediately upon receipt. As of June 30, 2023, the Partnership had an authorized amount of $ 755.3 million remaining under the program. Holdings of WES Operating equity. As of June 30, 2023, (i) the Partnership, directly and indirectly through its ownership of WES Operating GP, owned a 98.0 % limited partner interest and the entire non - economic general partner interest in WES Operating and (ii) Occidental, through its ownership of WGRAH, owned a 2.0 % limited partner interest in WES Operating, which is reflected as a noncontrolling interest within the consolidated financial statements of the Partnership (see Note 1 ). Partnership’s net income (loss) per common unit. The common and general partner unitholders’ allocation of net income (loss) attributable to the Partnership was equal to their cash distributions plus their respective allocations of undistributed earnings or losses in accordance with their weighted - average ownership percentage during each period using the two - class method. The Partnership’s basic net income (loss) per common unit is calculated by dividing the limited partners’ interest in net income (loss) by the weighted - average number of common units outstanding during the period. Diluted net income (loss) per common unit includes the effect of outstanding units issued under the Partnership’s long-term incentive plans. The following table provides a reconciliation between basic and diluted net income (loss) per common unit: Three Months Ended June 30, Six Months Ended June 30, thousands except per-unit amounts 2023 2022 2023 2022 Net income (loss) Limited partners’ interest in net income (loss) $ 247,100 $ 299,550 $ 446,059 $ 601,484 Weighted-average common units outstanding Basic 384,614 403,027 384,542 403,140 Dilutive effect of non-vested phantom units 896 1,135 1,123 1,140 Diluted 385,510 404,162 385,665 404,280 Excluded due to anti-dilutive effect 1,159 618 873 731 Net income (loss) per common unit Basic $ 0.64 $ 0.74 $ 1.16 $ 1.49 Diluted $ 0.64 $ 0.74 $ 1.16 $ 1.49 WES Operating’s net income (loss) per common unit. Net income (loss) per common unit for WES Operating is not calculated because it has no publicly traded units. 21 Table of Contents WESTERN MIDSTREAM PARTNERS, LP AND WESTERN MIDSTREAM OPERATING, LP NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 5.

Includes distributions made from WES Operating to the Partnership that were used by the Partnership to repurchase common units. See Note 3 and Note 4 . Related-party revenues. Related - party revenues include amounts earned by the Partnership from services provided to Occidental and from the sale of natural gas, condensate, and NGLs to Occidental. Gathering and processing agreements. The Partnership has significant gathering, processing, and produced-water disposal arrangements with affiliates of Occidental on most of its systems. While Occidental is the contracting counterparty of the Partnership, these arrangements with Occidental include not just Occidental - produced volumes, but also, in some instances, the volumes of other working - interest owners of Occidental who rely on the Partnership’s facilities and infrastructure to bring their volumes to market. Natural-gas throughput (excluding equity-investment throughput) attributable to production owned or controlled by Occidental was 34 % and 35 % for the three and six months ended June 30, 2023, respectively, and 35 % and 36 % for the three and six months ended June 30, 2022, respectively. Crude-oil and NGLs throughput (excluding equity-investment throughput) attributable to production owned or controlled by Occidental was 87 % and 88 % for the three and six months ended June 30, 2023, respectively, and 88 % and 89 % for the three and six months ended June 30, 2022, respectively. Produced-water throughput attributable to production owned or controlled by Occidental was 76 % and 78 % for the three and six months ended June 30, 2023, respectively, and 81 % and 82 % for the three and six months ended June 30, 2022, respectively. The Partnership is currently discussing varying interpretations of certain contractual provisions with Occidental regarding the calculation of the cost - of - service rates under an oil - gathering contract related to the Partnership’s DJ Basin oil - gathering system. If such discussions are resolved in a manner adverse to the Partnership, such resolution could have a negative impact on the Partnership’s financial condition and results of operations, including a reduction in rates and a non - cash charge to earnings. In connection with the sale of its Eagle Ford assets in 2017, Anadarko remained the primary counterparty to the Partnership’s Brasada gas processing agreement and entered into an agency relationship with Sanchez Energy Corporation (“Sanchez”), now Mesquite Energy, Inc. (“Mesquite”), that allowed Mesquite to process gas under such agreement. In December 2021, the Brasada gas processing agreement was assigned from Anadarko to Mesquite effective July 1, 2023. For this reason, Anadarko is not liable for any obligations under the Brasada gas processing agreement after June 30, 2023. For all periods presented, Mesquite performed Anadarko’s obligations under the Brasada gas processing agreement pursuant to its agency arrangement with Anadarko. Further, in connection with the sale of its Uinta Basin assets in 2020, Kerr McGee Oil & Gas Onshore LP, a subsidiary of Occidental, retained the deficiency payment obligations under a gas processing agreement at the Chipeta plant. This contingent payment obligation ended as of September 30, 2022. Marketing Transition Services Agreement. During the year ended December 31, 2020, Occidental provided marketing-related services to certain of the Partnership’s subsidiaries (the “Marketing Transition Services Agreement”). While the Partnership still has some marketing agreements with affiliates of Occidental, on January 1, 2021, the Partnership began marketing and selling substantially all of its crude oil and residue gas, and a majority of its NGLs, directly to third parties. 24 Table of Contents WESTERN MIDSTREAM PARTNERS, LP AND WESTERN MIDSTREAM OPERATING, LP NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 5. RELATED-PARTY TRANSACTIONS Related-party expenses. Operation and maintenance expense includes amounts accrued for or paid to related parties for field - related costs, shared field offices, and easements (see Related-party commercial agreement below) supporting the Partnership’s operations at certain assets. A portion of general and administrative expense is paid by Occidental, which results in related - party transactions pursuant to the reimbursement provisions of the Partnership’s and WES Operating’s agreements with Occidental. Cost of product expense includes amounts related to certain continuing marketing arrangements with affiliates of Occidental, related - party imbalances, and transactions with affiliates accounted for under the equity method of accounting. Related - party expenses bear no direct relationship to related - party revenues, and third - party expenses bear no direct relationship to third - party revenues. Services Agreement. Occidental performed certain centralized corporate functions for the Partnership and WES Operating pursuant to the agreement dated as of December 31, 2019, by and among Occidental, Anadarko, and WES Operating GP (“Services Agreement”). Most of the administrative and operational services previously provided by Occidental fully transitioned to the Partnership by December 31, 2021, with certain limited transition services remaining in place pursuant to the terms of the Services Agreement. Construction reimbursement agreements and purchases and sales with related parties . From time to time, the Partnership enters into construction reimbursement agreements with Occidental providing that the Partnership will manage the construction of certain midstream infrastructure for Occidental in the Partnership’s areas of operation. Such arrangements generally provide for a reimbursement of costs incurred by the Partnership on a cost or cost-plus basis. Additionally, from time to time, in support of the Partnership’s business, the Partnership purchases and sells equipment, inventory, and other miscellaneous assets from or to Occidental or its affiliates. Related-party commercial agreement. During the first quarter of 2021, an affiliate of Occidental and certain wholly owned subsidiaries of the Partnership entered into a Commercial Understanding Agreement (“CUA”). Under the CUA, certain West Texas surface - use and salt - water disposal agreements were amended to reduce usage fees owed by the Partnership in exchange for the forgiveness of certain deficiency fees owed by Occidental and other unrelated contractual amendments. The present value of the reduced usage fees under the CUA was $ 30.0 million at the time the agreement was executed. Also, as a result of the amendments under the CUA, these agreements are classified as operating leases and a $ 30.0 million right-of-use (“ROU”) asset, included in Other assets on the consolidated balance sheets, was recognized during the first quarter of 2021. The ROU asset is being amortized to Operation and maintenance expense through 2038, the remaining term of the agreements. Customer concentration. Occidental was the only customer from which revenues exceeded 10% of consolidated revenues for all periods presented in the consolidated statements of operations. 25 Table of Contents WESTERN MIDSTREAM PARTNERS, LP AND WESTERN MIDSTREAM OPERATING, LP NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 6.

Long-lived asset impairments. During the six months ended June 30, 2023, the Partnership recognized a long-lived asset impairment of $ 52.1 million for assets located in the Rockies due to a reduction in estimated future cash flows resulting from a contract termination notice received in the first quarter of 2023. This asset was impaired to its estimated fair value of $ 22.8 million. The fair value was measured using the income approach and Level-3 fair value inputs. The income approach was based on the Partnership’s projected future earnings before interest, taxes, depreciation, and amortization (“EBITDA”) and free cash flows, which requires significant assumptions including, among others, future throughput volumes based on current expectations of producer activity and operating costs. 27 Table of Contents WESTERN MIDSTREAM PARTNERS, LP AND WESTERN MIDSTREAM OPERATING, LP NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 8.

DEBT AND INTEREST EXPENSE WES Operating Senior Notes. WES Operating issued the Fixed - Rate 3.100 % Senior Notes due 2025, 4.050 % Senior Notes due 2030, 5.250 % Senior Notes due 2050, and the Floating - Rate Senior Notes due 2023 in January 2020. 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 3.791 %, 4.671 %, and 5.869 %, respectively, at June 30, 2023, and were 3.790 %, 4.671 %, and 5.869 %, respectively, at June 30, 2022. The effective interest rate of these notes is subject to adjustment from time to time due to a change in credit rating. During the second quarter of 2023, WES Operating completed the public offering of $ 750.0 million in aggregate principal amount of 6.150 % Senior Notes due 2033. Interest is payable semi-annually on April 1st and October 1st of each year, with the initial interest payment being due on October 1, 2023. Net proceeds from the offering were used to repay borrowings under the RCF and for general partnership purposes. Also during the second quarter of 2023, WES Operating purchased and retired $ 117.6 million of certain of its senior notes via open-market repurchases (see Debt activity above). For the three months ended June 30, 2023, a gain of $ 6.8 million was recognized for the early retirement of portions of these notes. Subsequent to June 30, 2023, WES Operating purchased and retired $ 159.1 million of certain of its senior notes via open-market repurchases. During the first quarter of 2023, WES Operating redeemed the total principal amount outstanding on the Floating-Rate Senior Notes due 2023 at par value with cash on hand. During the second quarter of 2022, WES Operating (i) redeemed the total principal amount outstanding of the 4.000 % Senior Notes due 2022 at par value and (ii) purchased and retired $ 1.4 million of the 3.100 % Senior Notes due 2025 via open-market repurchases. As of June 30, 2023, WES Operating was in compliance with all covenants under the relevant governing indentures. Revolving credit facility. In April 2023, WES Operating (i) repaid all then-outstanding borrowings under its senior unsecured revolving credit facility (“RCF”) with proceeds from the 6.150 % Senior Notes due 2033 offering, and (ii) entered into an amendment to its RCF to, among other things, extend the maturity date to April 2028 and provide for a maximum borrowing capacity up to $ 2.0 billion, expandable to maximum of $ 2.5 billion, through the maturity date. As of June 30, 2023, 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. As of June 30, 2023 and 2022, the interest rate on any outstanding RCF borrowings was 6.44 % and 3.12 %, respectively. The facility - fee rate was 0.20 % and 0.25 % at June 30, 2023 and 2022, respectively. As of June 30, 2023, WES Operating was in compliance with all covenants under the RCF. Interest expense.

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 producer activity. Our business is primarily driven by the level of production of crude-oil and natural gas by producers in our areas of operation. This activity, however, can be impacted negatively by, among other things, commodity-price fluctuations and operational challenges. Fluctuating crude - oil, natural - gas, and NGLs prices can reduce the level of our customers’ activities and change the allocation of capital within their own asset portfolios. Such fluctuations can also impact us directly to the extent we take ownership of and sell certain volumes at the tailgate of our plants for our own account. During 2020, oil and natural - gas prices were negatively impacted by the worldwide macroeconomic downturn that followed the global outbreak of COVID - 19. In 2021, prices began to increase and in the first quarter of 2022, commodity prices increased significantly in connection with the war in Ukraine. For example, the New York Mercantile Exchange (“NYMEX”) West Texas Intermediate crude - oil daily settlement prices during 2022 ranged from a high of $123.70 per barrel in March 2022 to a low of $71.02 per barrel in December 2022, and prices during the six months ended June 30, 2023, ranged from a high of $83.26 per barrel in April 2023 to a low of $66.74 per barrel in March 2023. The extent and duration of commodity - price volatility, and the associated direct and indirect impact on our business, cannot be predicted. To address the risks posed by fluctuating commodity prices, we intend to continue evaluating the relevant price environments and adjust our capital spending plans to reflect our customers’ anticipated activity levels, while maintaining appropriate liquidity and financial flexibility. Additionally, even when the commodity-price environments are favorable, our customers must manage numerous operational challenges, including severe weather disruptions, downstream and produced-water takeaway constraints, seismicity concerns, new regulatory requirements, and the ability to optimize the efficiency and results of large, complex drilling programs. Our producers’ ability to mitigate or manage such challenges can have a significant impact on the volumes available for us to service in the short term. For this reason, we strive to work proactively with our customers whenever possible to provide high levels of reliability on our systems and help them meet these operational challenges as they arise. Impact of inflation and supply-chain disruptions. The U.S. economy has recently experienced significant inflation relative to historical precedent, from, among other things, supply-chain disruptions caused by, or governmental stimulus or fiscal policies adopted in response to, the COVID-19 crisis and in connection with the war in Ukraine. More specifically, the bottlenecks and disruptions from the lingering effects of the COVID-19 crisis have caused difficulties within the U.S. and global supply chains, creating logistical delays along with labor shortages. Continued inflation has raised our costs for labor, materials, fuel, and services, which has increased our operating costs and capital expenditures. Increases in inflationary pressure could materially and negatively impact our financial results. To the extent permitted by regulations and escalation provisions in certain of our existing agreements, we have the ability to recover a portion of increased costs in the form of higher fees. Impact of interest rates. Short- and long-term interest rates increased during 2022, and have continued to increase during 2023, resulting in increased interest expense on RCF borrowings. Any future increases in interest rates likely will result in additional increases in financing costs. As with other yield-oriented securities, our unit price could be impacted by our implied distribution yield relative to market interest rates. Therefore, changes in interest rates, either positive or negative, may affect the yield requirements of investors who invest in our units, and a rising interest-rate environment could have an adverse impact on our unit price and our ability to issue additional equity, or increase the cost of issuing equity, to make acquisitions, to reduce debt, or for other purposes. However, we expect our cost of capital to remain competitive, as our competitors face similar interest-rate dynamics. 36 Table of Contents ACQUISITIONS AND DIVESTITURES Cactus II. In November 2022, we sold our 15.00% interest in Cactus II to two third parties for $264.8 million, which includes a $1.8 million pro-rata distribution through closing. Total proceeds were received during the fourth quarter of 2022, resulting in a net gain on sale of $109.9 million that was recorded as Gain (loss) on divestiture and other, net in the consolidated statements of operations. Ranch Westex. In September 2022, we acquired the remaining 50% interest in Ranch Westex from a third party for $40.1 million. Subsequent to the acquisition, (i) we are the sole owner and operator of the asset, (ii) Ranch Westex is no longer accounted for under the equity method of accounting, and (iii) the Ranch Westex processing plant is included as part of the operations of the West Texas complex.

(2) For all periods presented, includes (i) the 2.0% limited partner interest in WES Operating owned by an Occidental subsidiary and (ii) for natural - gas assets, the 25% third - party interest in Chipeta, which collectively represent WES’s noncontrolling interests. Natural-gas assets Total throughput attributable to WES for natural - gas assets increased by 147 MMcf/d for the three months ended June 30, 2023, primarily due to (i) higher volumes at the Chipeta complex due to volumes being diverted away from the plant for part of December 2022 through February 2023, (ii) higher volumes at the West Texas complex due to increased production in the area, (iii) higher volumes on Red Bluff Express, (iv) higher volumes around the Granger complex due to production declines and extended winter weather conditions during the first quarter of 2023, and (v) higher volumes at the MIGC system. Total throughput attributable to WES for natural - gas assets increased by 16 MMcf/d for the six months ended June 30, 2023, primarily due to higher volumes at the West Texas complex due to increased production in the area. This increase was offset partially by (i) lower volumes due to production declines in the areas around the Marcellus Interest systems and DJ Basin complex, (ii) decreased volumes at the Ranch Westex plant, which we acquired in the third quarter of 2022 and is included as part of the West Texas complex subsequent to the acquisition, (iii) lower volumes due to production declines and extended winter weather conditions during the first quarter of 2023 in areas around the Granger and Red Desert complexes, (iv) lower volumes at the Brasada complex due to downstream issues causing volumes to be diverted away from the plant and maintenance activities, (v) lower volumes at the Chipeta complex due to volumes being diverted away from the plant for part of December 2022 through February 2023, and (vi) lower volumes at the Mi Vida plant. 38 Table of Contents Crude-oil and NGLs assets Total throughput attributable to WES for crude - oil and NGLs assets increased by 15 MBbls/d for the three months ended June 30, 2023, primarily due to (i) higher volumes on the GNB NGL pipeline due to higher volumes received from the Chipeta complex compared to the first quarter of 2023 along with increased producer activity and (ii) higher volumes on the Saddlehorn pipeline. Total throughput attributable to WES for crude - oil and NGLs assets decreased by 51 MBbls/d for the six months ended June 30, 2023, primarily due to (i) lower volumes on the Cactus II pipeline, which was sold in the fourth quarter of 2022, and (ii) lower volumes at the DJ Basin oil system resulting from production declines in the area. These decreases were offset partially by (i) increased volumes on the Whitethorn pipeline and (ii) higher volumes at the DBM oil system resulting from increased production in the area. Produced-water assets Total throughput attributable to WES for produced - water assets increased by 142 MBbls/d for the six months ended June 30, 2023, due to higher production and new third-party connections brought online during the first half of 2023.

Income Tax Expense (Benefit) We are not a taxable entity for U.S. federal income tax purposes; therefore, our federal statutory rate is zero percent. However, income apportionable to Texas is subject to Texas margin tax. 43 Table of Contents RECONCILIATION OF NON-GAAP FINANCIAL MEASURES Adjusted gross margin. We define Adjusted gross margin attributable to Western 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 and NGLs imbalances, (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, and (iv) costs associated with our offload commitments with third parties providing firm-processing capacity. The electricity-related expenses included in our Adjusted gross margin definition relate to pass-through expenses that are reimbursed by certain customers (recorded as revenue with an offset recorded as Operation and maintenance expense). Adjusted EBITDA. We define Adjusted EBITDA attributable to Western 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. 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. 44 Table of Contents Adjusted gross margin, Adjusted EBITDA, and Free cash flow are not defined in GAAP. The GAAP measure that is most directly comparable to Adjusted gross margin is gross margin. Net income (loss) and net cash provided by operating activities are the GAAP measures that are most directly comparable to Adjusted EBITDA. The GAAP measure 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 gross margin, 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 gross margin, 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) gross margin, 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 gross margin 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 Six Months Ended thousands June 30, 2023 March 31, 2023 June 30, 2023 June 30, 2022 Reconciliation of Gross margin to Adjusted gross margin Total revenues and other $ 738,273 $ 733,982 $ 1,472,255 $ 1,634,716 Less: Cost of product 44,746 51,459 96,205 221,404 Depreciation and amortization 143,492 144,626 288,118 273,618 Gross margin 550,035 537,897 1,087,932 1,139,694 Add: Distributions from equity investments 54,075 51,975 106,050 121,811 Depreciation and amortization 143,492 144,626 288,118 273,618 Less: Reimbursed electricity-related charges recorded as revenues 23,286 23,569 46,855 37,446 Adjusted gross margin attributable to noncontrolling interests (1) 16,914 15,774 32,688 37,256 Adjusted gross margin $ 707,402 $ 695,155 $ 1,402,557 $ 1,460,421 _________________________________________________________________________________________ (1) For all periods presented, includes (i) the 25% third - party interest in Chipeta and (ii) the 2.0% limited partner interest in WES Operating owned by an Occidental subsidiary, which collectively represent WES’s noncontrolling interests. 45 Table of Contents To facilitate investor and industry analysis, 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. Adjusted gross margin increased by $12.2 million for the three months ended June 30, 2023, primarily due to (i) increased throughput at the Chipeta, DJ Basin, and Granger complexes, and (ii) an increase in distributions from Saddlehorn. Adjusted gross margin decreased by $57.9 million for the six months ended June 30, 2023, primarily due to (i) a decrease in distributions from Cactus II, which was sold in the fourth quarter of 2022, (ii) decreased deficiency fees and throughput at the Chipeta complex, (iii) decreased throughput at the DJ Basin complex, DJ Basin oil system, and Granger complex, and (iv) a decrease in distributions from Ranch Westex, which was acquired in the third quarter of 2022 and is included in the West Texas complex subsequent to the acquisition. These decreases were partially offset by increased throughput at the West Texas complex. Per - Mcf Adjusted gross margin for natural - gas assets decreased by $0.04 for the three months ended June 30, 2023, primarily due to higher throughput across several assets that have lower-than average per-Mcf margins as compared to our other natural-gas assets. Per - Mcf Adjusted gross margin for natural - gas assets decreased by $0.07 for the six months ended June 30, 2023, primarily due to contract mix and lower commodity prices, partially offset by increased throughput at the West Texas complex. Per - Bbl Adjusted gross margin for crude - oil and NGLs assets decreased by $0.07 for the three months ended June 30, 2023, primarily due to decreases in demand-fee revenue and throughput at the DJ Basin oil system, which has a higher-than-average per-Bbl margin as compared to our other crude-oil and NGLs assets. Per - Bbl Adjusted gross margin for crude - oil and NGLs assets increased by $0.11 for the six months ended June 30, 2023, primarily due to (i) decreases in throughput and distributions from Cactus II, which was sold in the fourth quarter of 2022, and had lower-than-average per-Bbl margin as compared to our other crude-oil and NGLs assets and (ii) increases in distributions from FRP and TEP. Per - Bbl Adjusted gross margin for produced - water assets increased by $0.02 for the three months ended June 30, 2023, primarily due to increased throughput on certain fee-based contracts. Per - Bbl Adjusted gross margin for produced - water assets decreased by $0.13 for the six months ended June 30, 2023, primarily due to a lower average fee resulting from a cost-of-service rate redetermination effective January 1, 2023, and lower deficiency fee revenues. 49 Table of Contents Adjusted EBITDA. Adjusted EBITDA decreased by $10.3 million for the three months ended June 30, 2023, primarily due to (i) an $11.7 million increase in property and other taxes and (ii) a $9.2 million increase in operation and maintenance expenses. These amounts were offset partially by (i) a $6.7 million decrease in cost of product (net of lower of cost or market inventory adjustments), (ii) a $4.3 million increase in total revenues and other, and (iii) a $2.1 million increase in distributions from equity investments. Adjusted EBITDA decreased by $100.3 million for the six months ended June 30, 2023, primarily due to (i) a $162.5 million decrease in total revenues and other, (ii) a $60.5 million increase in operation and maintenance expenses, (iii) a $15.8 million decrease in distributions from equity investments, and (iv) an $8.0 million increase in general and administrative expenses excluding non - cash equity - based compensation expense. These amounts were offset partially by (i) a $125.5 million decrease in cost of product (net of lower of cost or market inventory adjustments) and (ii) a $15.7 million decrease in property and other taxes. Free cash flow. Free cash flow increased by $198.5 million for the three months ended June 30, 2023, primarily due to (i) a $188.4 million increase in net cash provided by operating activities and (ii) an $11.6 million decrease in capital expenditures. Free cash flow decreased by $90.7 million for the six months ended June 30, 2023, primarily due to a $143.2 million increase in capital expenditures, offset partially by (i) a $49.8 million increase in net cash provided by operating activities and (ii) a $4.9 million decrease in contributions to equity investments. See Capital Expenditures and Historical Cash Flow within this Item 2 for further information. LIQUIDITY AND CAPITAL RESOURCES Our primary cash uses include equity and debt service, operating expenses, and capital expenditures. Our sources of liquidity as of June 30, 2023, 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 and debt-service requirements. The amount of future distributions to unitholders will be determined by the Board on a quarterly basis. 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) 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. The Board declared a cash distribution to unitholders for the second quarter of 2023 of $0.5625 per unit, a 12.5% increase from the prior quarter, or $221.4 million in the aggregate. The cash distribution is payable on August 14, 2023, to our unitholders of record at the close of business on July 31, 2023. To facilitate the distribution of available cash, during 2022 we adopted a financial policy that provided for an additional distribution (“Enhanced Distribution”) to be paid in conjunction with the regular first-quarter distribution of the following year (beginning in 2023), in a target amount equal to Free cash flow generated in the prior year after subtracting Free cash flow used for the prior year’s debt repayments, regular-quarter distributions, and unit repurchases. This Enhanced Distribution is subject to Board discretion, the establishment of cash reserves for the proper conduct of our business and is also contingent on the attainment of prior year-end net leverage thresholds (the ratio of our total principal debt outstanding less total cash on hand as of the end of such period, as compared to our trailing-twelve-months Adjusted EBITDA), after taking the Enhanced Distribution for such prior year into effect. Free cash flow and Adjusted EBITDA are defined under the caption Reconciliation of Non-GAAP Financial Measures within this Item 2. In April 2023, the Board approved an Enhanced Distribution of $0.356 per unit, or $140.1 million, related to our 2022 performance, which was paid in conjunction with our regular first-quarter 2023 distribution on May 15, 2023. 50 Table of Contents In 2022, we announced a common-unit buyback program of up to $1.25 billion through December 31, 2024. 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 our 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 six months ended June 30, 2023, we repurchased 287,322 common units for an aggregate purchase price of $7.1 million. The units were canceled immediately upon receipt. As of June 30, 2023, we had an authorized amount of $755.3 million remaining under the program. For the year ended December 31, 2023, capital expenditures are expected to range between $700.0 million to $800.0 million (accrual-based, includes equity investments, excludes capitalized interest, and excludes capital expenditures associated with the 25% third-party interest in Chipeta), representing a $125.0 million increase to the midpoint of our previously announced guidance in February 2023. Total-year capital expenditures guidance includes capital expenditures attributable to (i) a portion of Mentone Train III, (ii) a portion of the North Loving plant, a new 250 MMcf/d cryogenic processing plant in the North Loving area of our West Texas complex that was sanctioned in May 2023, and (iii) additional expansion capital needed to support new commercial activity. Management continuously monitors our leverage position and other financial projections to manage the capital structure according to long-term objectives. We may, from time to time, seek to retire, rearrange, or amend some or all of our outstanding debt or financing 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 and the amounts involved may be material. 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 . 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 of June 30, 2023, we had a $175.7 million working capital surplus, which we define as the amount by which current assets exceed current liabilities. As of June 30, 2023, there was $2.0 billion available for borrowing under the RCF. See Note 8—Selected Components of Working Capital and Note 9—Debt and Interest Expense in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q. 51 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 include maintenance capital expenditures, which include those expenditures required to maintain existing operating capacity and service capability of our assets, and expansion capital expenditures, which include expenditures to construct new midstream infrastructure and expenditures incurred to reduce costs, increase revenues, or increase system throughput or capacity from current levels. 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. Capital expenditures as presented in the consolidated statements of cash flows and capital incurred were as follows: Six Months Ended June 30, thousands 2023 2022 Capital expenditures (1) $ 334,570 $ 191,357 Capital incurred (1) 368,683 207,996 _________________________________________________________________________________________ (1) For the six months ended June 30, 2023 and 2022, included $5.1 million and $2.0 million, respectively, of capitalized interest. Capital expenditures increased by $143.2 million for the six months ended June 30, 2023, primarily due to increases of (i) $66.5 million at the West Texas complex, primarily attributable to facility expansion, including ongoing construction of Mentone Train III, and pipeline projects, (ii) $54.3 million at the DBM water systems due to construction of additional water - disposal wells and facilities and pipeline projects, and (iii) $17.1 million at the DBM oil system, primarily related to an increase in pipeline, oil treating, and oil pumping projects. Historical cash flow . The following table and discussion present a summary of our net cash flows provided by (used in) operating, investing, and financing activities: Six Months Ended June 30, thousands 2023 2022 Net cash provided by (used in): Operating activities $ 793,247 $ 743,439 Investing activities (330,668) (170,947) Financing activities (535,282) (677,057) Net increase (decrease) in cash and cash equivalents $ (72,703) $ (104,565) Operating activities . Net cash provided by operating activities increased for the six months ended June 30, 2023, primarily due to the impact of changes in assets and liabilities. This increase was partially offset by (i) lower cash operating income, (ii) lower distributions from equity investments, and (iii) higher interest expense. Refer to Operating Results within this Item 2 for a discussion of our results of operations as compared to the prior periods. Investing activities . Net cash used in investing activities for the six months ended June 30, 2023, primarily included the following: • $334.6 million of capital expenditures, primarily related to construction, expansion, and asset - integrity projects at the West Texas complex, DBM water systems, DBM oil system, and DJ Basin complex; • $19.1 million of increases to materials and supplies inventory; and • $23.2 million of distributions received from equity investments in excess of cumulative earnings. Net cash used in investing activities for the six months ended June 30, 2022, primarily included the following: • $191.4 million of capital expenditures, primarily related to construction, expansion, and asset - integrity projects at the West Texas complex, DBM water systems, DJ Basin complex, and DBM oil system; 52 Table of Contents • $5.0 million of capital contributions primarily paid to Red Bluff Express; and • $25.4 million of distributions received from equity investments in excess of cumulative earnings. Financing activities . Net cash used in financing activities for the six months ended June 30, 2023, primarily included the following: • $595.0 million of repayments of outstanding borrowings under the RCF; • $548.2 million of distributions paid to WES unitholders and noncontrolling interest owners; • $213.1 million to redeem the total principal amount outstanding on the Floating-Rate Senior Notes due 2023 at par value; • $110.2 million to purchase and retire portions of certain of WES Operating’s senior notes via open-market repurchases; • $7.1 million of unit repurchases; • $740.9 million of net proceeds from the 6.150% Senior Notes due 2033 issued in April 2023, which were used to repay borrowings under the RCF and for general partnership purposes; and • $220.0 million of borrowings under the RCF, which were used for general partnership purposes. Net cash used in financing activities for the six months ended June 30, 2022, primarily included the following: • $883.5 million to redeem the total principal amount outstanding of WES Operating’s 4.000% Senior Notes due 2022 and repay borrowings under the RCF; • $340.9 million of distributions paid to WES unitholders; • $79.2 million of unit repurchases; • $8.8 million of distributions paid to the noncontrolling interest owner of WES Operating; • $3.2 million of distributions paid to the noncontrolling interest owner of Chipeta; • $634.0 million of borrowings under the RCF, which were used for general partnership purposes and to redeem portions of certain of WES Operating’s senior notes; and • $13.0 million of increases in outstanding checks. 53 Table of Contents Debt and credit facilities. As of June 30, 2023, the carrying value of outstanding debt was $6.8 billion, we have no borrowings due within the next year, and have $2.0 billion of available borrowing capacity under WES Operating’s $2.0 billion RCF. During the second quarter of 2023, WES Operating (i) completed the public offering of $750.0 million in aggregate principal amount of 6.150% Senior Notes due 2033, (ii) entered into an amendment to our RCF to, among other things, extend the maturity date to April 2028 and provide for a maximum borrowing capacity up to $2.0 billion through the maturity date, and (iii) purchased and retired $117.6 million of certain of its senior notes via open-market repurchases. In May 2023, Fitch Ratings upgraded WES Operating’s long-term debt from “BB+” to “BBB-.” WES Operating’s senior unsecured debt ratings is now investment grade at Standard and Poor’s, Moody’s Investors Services, and Fitch Ratings. As a result of the upgrade, annualized borrowing costs will decrease by $6.9 million on WES Operating’s senior notes that are subject to effective interest-rate adjustments from a change in credit rating. Subsequent to June 30, 2023, WES Operating purchased and retired $159.1 million of certain of its senior notes via open-market repurchases. For additional information on our senior notes and the RCF, see Note 9—Debt and Interest Expense in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q. Offload commitments. We have entered into offload agreements with third parties providing firm-processing capacity through 2025. As of June 30, 2023, we have future minimum payments under offload agreements totaling $9.2 million for the remainder of 2023 and a total of $11.7 million in years thereafter. Pipeline commitments. We have entered into transportation contracts with volume commitments on multiple pipelines through 2033. As of June 30, 2023, we have estimated future minimum-volume-commitment fees totaling $3.1 million for the remainder of 2023, and a total of $51.7 million in years thereafter. 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- or NGLs-imbalance agreements. We examine and monitor the creditworthiness of customers and may establish credit limits for customers. 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. See Note 5—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. 54 Table of Contents ITEMS AFFECTING THE COMPARABILITY OF FINANCIAL RESULTS WITH WES OPERATING Our consolidated financial statements include the consolidated financial results of WES Operating. Our results of operations do not differ materially from the results of operations and cash flows of WES Operating, which are reconciled below. Reconciliation of net income (loss). The differences between net income (loss) attributable to WES and WES Operating are reconciled as follows: Three Months Ended Six Months Ended thousands June 30, 2023 March 31, 2023 June 30, 2023 June 30, 2022 Net income (loss) attributable to WES $ 252,921 $ 203,645 $ 456,566 $ 615,034 Limited partner interest in WES Operating not held by WES (1) 5,185 4,161 9,346 12,584 General and administrative expenses (2) 1,186 232 1,418 1,362 Other income (expense), net (129) (25) (154) (7) Net income (loss) attributable to WES Operating $ 259,163 $ 208,013 $ 467,176 $ 628,973 _________________________________________________________________________________________ (1) Represents the portion of net income (loss) allocated to the limited partner interest in WES Operating not held by WES.

(2) Represents general and administrative expenses incurred by WES separate from, and in addition to, those incurred by WES Operating. Reconciliation of net cash provided by (used in) operating and financing activities. The differences between net cash provided by (used in) operating and financing activities for WES and WES Operating are reconciled as follows: Six Months Ended June 30, thousands 2023 2022 WES net cash provided by operating activities $ 793,247 $ 743,439 General and administrative expenses (1) 1,418 1,362 Non - cash equity - based compensation expense (287) (276) Changes in working capital (14,327) (7,835) Other income (expense), net (154) (7) WES Operating net cash provided by operating activities $ 779,897 $ 736,683 WES net cash provided by (used in) financing activities $ (535,282) $ (677,057) Distributions to WES unitholders (2) 533,556 340,946 Distributions to WES from WES Operating (3) (545,277) (431,653) Increase (decrease) in outstanding checks — 104 Unit repurchases 7,102 79,217 Other 13,415 7,007 WES Operating net cash provided by (used in) financing activities $ (526,486) $ (681,436) _________________________________________________________________________________________ (1) Represents general and administrative expenses incurred by WES separate from, and in addition to, those incurred by WES Operating. (2) Represents distributions to WES common unitholders paid under WES’s partnership agreement. See Note 3—Partnership Distributions and Note 4—Equity and Partners’ Capital in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q. (3) Difference attributable to elimination in consolidation of WES Operating’s distributions on partnership interests owned by WES. See Note 3—Partnership Distributions and Note 4—Equity and Partners’ Capital in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q. 55 Table of Contents Noncontrolling interest. WES Operating’s noncontrolling interest consists of the 25% third - party interest in Chipeta. See Note 1—Description of Business and Basis of Presentation in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q. WES Operating distributions. WES Operating distributes all of its available cash on a quarterly basis to WES Operating unitholders in proportion to their share of limited partner interests in WES Operating. See Note 3—Partnership Distributions in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q. CRITICAL ACCOUNTING ESTIMATES The preparation of consolidated financial statements in accordance with GAAP requires management to make informed judgments and estimates that affect the amounts of assets and liabilities as of the date of the financial statements and the amounts of revenues and expenses recognized during the periods reported. There have been no significant changes to our critical accounting estimates from those disclosed in our annual report on Form 10-K for the fiscal year ended December 31, 2022. Item 3. Quantitative and Qualitative Disclosures About Market Risk Commodity-price risk. There have been no significant changes to our commodity-price risk discussion from the disclosure set forth under Part II, Item 7A in our Form 10-K for the year ended December 31, 2022, except as noted below and in Outlook under Part I, Item 2 of this Form 10-Q. For the six months ended June 30, 2023, 95% of our wellhead natural - gas volume (excluding equity investments) and 100% of our crude - oil and produced - water throughput (excluding equity investments) were serviced under fee - based contracts. A 10% increase or decrease in commodity prices would not have a material impact on our operating income (loss), financial condition, or cash flows for the next 12 months, excluding the effect of imbalances. Interest-rate risk. The Federal Open Market Committee increased its target range seven times for the federal funds rate in 2022 and increased its target range three times during the six months ended June 30, 2023. Any future increases in the federal funds rate likely will result in an increase in financing costs. As of June 30, 2023, WES Operating had no outstanding borrowings under the RCF that bear interest at a rate based on the Secured Overnight Financing Rate (“SOFR”) or an alternative base rate at WES Operating’s option. While a 10% change in the applicable benchmark interest rate would not materially impact interest expense on our outstanding borrowings at June 30, 2023, it would impact the fair value of the senior notes. Additional variable - rate debt may be issued in the future, either under the RCF or other financing sources, including commercial paper borrowings or debt issuances. 56 Table of Contents Item 4. Controls and Procedures Evaluation of Disclosure Controls and Procedures . The Chief Executive Officer and Chief Financial Officer of WES’s general partner and WES Operating GP (for purposes of this Item 4, “Management”) performed an evaluation of WES’s and WES Operating’s disclosure controls and procedures as defined in Rules 13a - 15(e) and 15d - 15(e) of the Exchange Act. WES’s and WES Operating’s disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports that are filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the SEC, and to ensure that the information required to be disclosed in the reports that are filed or submitted under the Exchange Act is accumulated and communicated to management, including the principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Based on this evaluation, Management concluded that WES’s and WES Operating’s disclosure controls and procedures were effective as of June 30, 2023. Changes in Internal Control Over Financial Reporting . On April 1, 2023, WES and WES Operating implemented a new Enterprise Resource Planning (“ERP”) system. As a result of this implementation, certain internal controls over financial reporting have been automated, modified, or implemented to address the new environment associated with the implementation of this type of system. While WES and WES Operating believe that this system will strengthen the internal control system, there are inherent risks in implementing any new system and WES and WES Operating will continue to evaluate these control changes as part of their assessments of internal control over financial reporting. Other than the ERP implementation, there have been no changes in WES or WES Operating’s internal control over financial reporting that occurred during the quarter ended June 30, 2023, that materially affected, or are reasonably likely to materially affect, WES or WES Operating’s internal control over financial reporting during the most recent fiscal quarter. 57 Table of Contents PART II. OTHER INFORMATION Item 1. Legal Proceedings In 2020, the U.S. Department of Justice, on behalf of the U.S. Environmental Protection Agency (the “EPA”), and the State of Colorado, on behalf of the Colorado Department of Public Health and the Environment (the “CDPHE”) commenced an enforcement action in the United States District Court for the District of Colorado against Kerr - McGee Gathering LLC (“KMG”), a wholly owned subsidiary of WES, for alleged non - compliance with the leak detection and repair requirements of the federal Clean Air Act and the Colorado Air Pollution Prevention and Control Act at its Fort Lupton, Platte Valley, and Lancaster facilities in the DJ Basin complex. We reached an agreement to resolve these allegations with the EPA and the CDPHE pursuant to a consent decree that became effective on June 15, 2023. While such resolution includes an injunctive relief component and payment of a civil penalty, which exceeds the disclosure threshold amount required by Item 103 of Regulation S-K, the resolution of these claims did not have a material impact on WES’s results of operations, cash flows, or financial condition. On October 29, 2020, WGR Operating, LP (“WGR”), on behalf of itself and derivatively on behalf of Mont Belvieu JV, filed suit against Enterprise Products Operating, LLC (“Enterprise”) and Mont Belvieu JV (as a nominal defendant) in the District Court of Harris County, Texas. Our lawsuit seeks a declaratory judgment regarding proper revenue allocation as set forth in the Operating Agreement between Mont Belvieu JV (of which WGR is a 25% owner) and Enterprise (the “Operating Agreement”) related to fractionation trains at the Mont Belvieu complex in Chambers County, Texas. Specifically, the Operating Agreement sets forth a revenue allocation structure, whereby revenue would be allocated to the various fracs at the Mont Belvieu complex in sequential order, with Fracs VII and VIII (which are owned by Mont Belvieu JV) following Fracs I through VI, but preceding any “Later Frac Facilities.” Subsequent to the construction of Fracs VII and VIII, Enterprise built Fracs IX, X, and XI, which it wholly owns, and has treated such subsequent fracs as outside the Mont Belvieu revenue allocation. We do not believe Enterprise’s attempt to bypass the agreed - to revenue allocation is proper under the parties’ agreements and now seek judicial determination. We currently sue only for declaratory judgment to avoid potential future damages. We cannot make any assurances regarding the ultimate outcome of this proceeding and its resulting impact on WGR or WES. On November 22, 2022, WGR filed suit against Enterprise Crude Oil LLC (“ECO”) in the District Court of Harris County, Texas. Our lawsuit alleges that ECO breached a contract related to the Whitethorn joint venture pursuant to which ECO must share with WGR certain of the profits and losses generated by ECO’s hydrocarbon trading activity conducted utilizing the Whitethorn pipeline. Specifically, we claim that ECO has engaged in trades knowing that the revenue to be realized would be less than the minimum floor set under the contract and has failed to allocate revenues and expenses as prescribed by the contract, resulting in improper losses to WGR. Enterprise has filed a counterclaim to our lawsuit, alleging that, between 2017 and 2019, it had mistakenly overpaid WGR approximately $12.0 million in trading profits and seeking recovery of such amount. We cannot make any assurances regarding the ultimate outcome of this proceeding and its resulting impact on WGR or WES. Except as discussed above, we are not a party to any legal, regulatory, or administrative proceedings other than proceedings arising in the ordinary course of business. Management believes that there are no such proceedings for which a final disposition could have a material adverse effect on results of operations, cash flows, or financial condition, or for which disclosure is otherwise required by Item 103 of Regulation S - K. 58 Table of Contents Item 1A. Risk Factors Security holders and potential investors in our securities should carefully consider the risk factors set forth under Part I, Item 1A in our Form 10 - K for the year ended December 31, 2022, together with all of the other information included in this document, and in our other public filings, press releases, and public discussions with management.

See Note 4—Equity and Partners’ Capital in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q for additional details. Item 5. Other Information Insider Trading Arrangements Rule 10b5-1 under the Exchange Act provides an affirmative defense that enables prearranged transactions in securities in a manner that avoids concerns about initiating transactions at a future date while possibly in possession of material nonpublic information. Our Insider Trading Policy permits our directors and executive officers to enter into trading plans designed to comply with Rule 10b5-1. During the three months ended June 30, 2023, none of our executive officers or directors adopted or terminated a Rule 10b5-1 trading plan or adopted or terminated a non-Rule 10b5-1 trading arrangement (as defined in Item 408(c) of Regulation S-K). 59 Table of Contents Item 6.
