Western Midstream Operating, LP

General. Western Midstream Partners, LP (the “Partnership”) is a Delaware master limited partnership formed in September 2012. Western Midstream Operating, LP (together with its subsidiaries, “WES Operating”) is a Delaware limited partnership formed in 2007 to acquire, own, develop, and operate midstream assets. The Partnership owns, directly and indirectly, a 98.0% limited partner interest in WES Operating, and directly owns all of the outstanding equity interests of Western Midstream Operating GP, LLC, which holds the entire non-economic general partner interest in WES Operating. In addition, Occidental owns the Partnership’s general partner and a 2.0% limited partner interest in WES Operating through its ownership of WGR Asset Holding Company LLC (“WGRAH”).

For purposes of these consolidated financial statements, the Partnership refers to Western Midstream Partners, LP in its individual capacity or to Western Midstream Partners, LP and its subsidiaries, including Western Midstream Operating GP, LLC and WES Operating, as the context requires. “WES Operating GP” refers to Western Midstream Operating GP, LLC, individually as the general partner of WES Operating. The Partnership’s general partner, Western Midstream Holdings, LLC (the “general partner”), is a wholly owned subsidiary of Occidental Petroleum Corporation. “Occidental” refers to Occidental Petroleum Corporation, as the context requires, and its subsidiaries, excluding the general partner. “Related parties” refers to Occidental (see Note 6), the Partnership’s investments accounted for under the equity method of accounting (see Note 7), and WES Operating for transactions with the Partnership that eliminate upon consolidation (see Note 6).

The Partnership is engaged in the business of gathering, compressing, treating, processing, and transporting natural gas; gathering, stabilizing, and transporting condensate, natural-gas liquids (“NGLs”), and crude oil; and gathering and disposing of produced water. In its capacity as a natural-gas processor, the Partnership also buys and sells residue, NGLs, and condensate on behalf of itself and its customers under certain contracts. As of June 30, 2025, the Partnership’s assets and investments consisted of the following:

(1)Includes the DBM water systems.

These assets and investments are located in Texas, New Mexico, and the Rocky Mountains (Colorado, Utah, and Wyoming).

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 or other financial interest, including WES Operating, WES Operating GP, proportionately consolidated interests, and equity investments. All significant intercompany transactions have been eliminated.

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.

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 2024 Form 10-K, as filed with the SEC on February 26, 2025. Management believes that the disclosures made are adequate to make the information not misleading.

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.

Inventory. As of June 30, 2025, and December 31, 2024, Other current assets includes (i) $2.6 million and $2.5 million, respectively, of NGLs inventory and (ii) $9.3 million and $0.6 million, respectively, of materials and supplies inventory that are classified as short term on the consolidated balance sheets. As of June 30, 2025, and December 31, 2024, Other assets includes (i) $3.3 million and $5.5 million, respectively, of NGLs line-fill inventory, and (ii) $105.0 million and $110.3 million, respectively, of materials and supplies inventory that are classified as long term on the consolidated balance sheets.

Segments. The Partnership’s operations continue to be organized into a single operating segment, the assets of which gather, compress, treat, process, and transport natural gas; gather, stabilize, and transport condensate, NGLs, and crude oil; and gather and dispose of produced water in the United States.

Accounting Standards Update 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” was adopted on December 31, 2024, using a retrospective approach with no impact to the consolidated financial statements; however, the adoption did result in additional disclosure. See Note 11.

Equity-based compensation. During the six months ended June 30, 2025 and 2024, the Partnership issued 771,961 common units and 971,391 common units, respectively, under its long-term incentive plans. Compensation expense was $10.7 million and $19.0 million for the three and six months ended June 30, 2025, respectively, and $10.4 million and $19.8 million for the three and six months ended June 30, 2024, respectively.

New accounting pronouncements not yet adopted. In November 2024, the Financial Accounting Standards Board issued Accounting Standards Update 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation (Subtopic 220-40): Disaggregation of Income Statement Expenses.” The standard requires additional disclosure and disaggregation of certain income statement expense line items and may be applied prospectively or retrospectively. The Partnership plans to adopt the standard when it becomes effective beginning with the fiscal year 2027 annual financial statements. The Partnership is assessing the impact of this guidance on its disclosures in the Notes to the Consolidated Financial Statements.

2. REVENUE FROM CONTRACTS WITH CUSTOMERS

The following table summarizes revenue from contracts with customers:

Contract balances. Receivables from customers, which are included in Accounts receivable, net on the consolidated balance sheets, were $698.1 million and $693.9 million as of June 30, 2025, and December 31, 2024, respectively.

Contract assets primarily relate to (i) revenue accrued but not yet billed under cost-of-service contracts with fixed and variable fees and (ii) accrued deficiency fees the Partnership expects to charge customers once the related performance periods are completed. The following table summarizes activity related to contract assets from contracts with customers:

(1)Includes $(1.7) million for the three months ended June 30, 2025.

(2)Includes $0.8 million for the three months ended June 30, 2025.

2. REVENUE FROM CONTRACTS WITH CUSTOMERS

Contract liabilities primarily relate to (i) fixed and variable fees under cost-of-service contracts that are received from customers for which revenue recognition is deferred, (ii) aid-in-construction payments received from customers that must be recognized over the expected period of customer benefit, and (iii) fees that are charged to customers for only a portion of the contract term and must be recognized as revenues over the expected period of customer benefit.

The following table summarizes activity related to contract liabilities from contracts with customers:

(1)Includes $36.0 million for the three months ended June 30, 2025.

(2)Includes $(2.8) million for the three months ended June 30, 2025.

Transaction price allocated to remaining performance obligations. Revenues expected to be recognized from certain performance obligations that are unsatisfied (or partially unsatisfied) as of June 30, 2025, are presented in the table below. The Partnership applies the optional exemptions in Revenue from Contracts with Customers (Topic 606) and does not disclose consideration for remaining performance obligations with an original expected duration of one year or less or for variable consideration related to unsatisfied (or partially unsatisfied) performance obligations. Therefore, the following table represents only a portion of expected future revenues from existing contracts, as most future revenues from customers are dependent on future variable customer volumes and, in some cases, variable commodity prices for those volumes.

3. ACQUISITIONS AND DIVESTITURES

Marcellus Interest systems. During the second quarter of 2024, the Partnership closed on the sale of its 33.75% interest in the Marcellus Interest systems for proceeds of $206.2 million, resulting in a net gain on sale of $63.9 million that was recorded as Gain (loss) on divestiture and other, net in the consolidated statement of operations.

Mont Belvieu JV, Whitethorn LLC, Panola, and Saddlehorn. During the first quarter of 2024, the Partnership closed on the sale of the following equity investments to third parties: (i) the 25.00% interest in Enterprise EF78 LLC, (ii) the 20.00% interest in Whitethorn Pipeline Company LLC, (iii) the 15.00% interest in Panola Pipeline Company, LLC, and (iv) the 20.00% interest in Saddlehorn Pipeline Company, LLC. The combined proceeds received in the first quarter of 2024 of $588.6 million includes $5.9 million in pro-rata distributions through closing, resulting in a net gain on sale of $239.7 million that was recorded as Gain (loss) on divestiture and other, net in the consolidated statement of operations.

5. 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, 2025, Occidental held 165,681,578 common units, representing a 42.4% 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 215,647,026 common units, representing a 55.3% limited partner interest in the Partnership.

Partnership equity repurchases. In February 2025, the Board authorized the Partnership to buy back up to $250.0 million of the Partnership’s common units through December 31, 2026 (the “2025 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, 2025, the Partnership repurchasedno common units. As of June 30, 2025, the Partnership had an authorized amount of $250.0 million remaining under the program.

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 following table provides a reconciliation between basic and diluted net income (loss) per common unit:

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.

Summary of related-party transactions. The following tables summarize material related-party transactions included in the Partnership’s consolidated financial statements:

(1)See Note 7.

(2)Includes related-party natural-gas and NGLs imbalances.

(1)See Note 7.

(2)Includes contract liabilities from contracts with customers. See Note 2.

(1)Represents common and general partner unit distributions paid to Occidental pursuant to the partnership agreement of the Partnership. See Note 4 and Note 5.

(2)Represents distributions paid to Occidental, through its ownership of WGRAH, pursuant to WES Operating’s partnership agreement. See Note 4 and Note 5.

The following tables summarize material related-party transactions for WES Operating (which are included in the Partnership’s consolidated financial statements) to the extent the amounts differ materially from the Partnership’s consolidated financial statements:

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, treating, processing, stabilization, 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 36% for both the three and six months ended June 30, 2025, and 34% and 33% for the three and six months ended June 30, 2024, respectively. Crude-oil and NGLs throughput (excluding equity-investment throughput) attributable to production owned or controlled by Occidental was 92% for both the three and six months ended June 30, 2025, and 90% for both the three and six months ended June 30, 2024. Produced-water throughput attributable to production owned or controlled by Occidental was 79% and 80% for the three and six months ended June 30, 2025, respectively, and 77% for both the three and six months ended June 30, 2024.

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.

Marketing Services. Prior to January 1, 2021, Occidental provided marketing-related services to certain of the Partnership’s subsidiaries. While the Partnership now markets and sells substantially all of its crude oil, residue gas, and NGLs directly to third parties, it does still have some marketing agreements with affiliates of Occidental, the activity for which is reflected in the related-party statements of operations above.

Operating leases. Certain surface-use and salt-water disposal agreements between an affiliate of Occidental and certain wholly owned subsidiaries of the Partnership are classified as operating leases (see Related-party commercial agreement below). In addition, the Partnership has operating leases for field offices with Occidental as the lessor.

Related-party expenses. Operation and maintenance expense includes amounts accrued for or paid to related parties for field-related costs, field offices, and easements (see Related-party commercial agreement below) supporting the Partnership’s operations at certain assets. General and administrative expense includes amounts accrued for or paid to Occidental for certain reimbursed expenses pursuant to the 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. See Marketing Services in the section above. 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, between WES Operating GP and Occidental (“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 the Partnership amended certain West Texas surface-use and salt-water disposal agreements 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 amended agreements were $30.0 million at the time the agreement was executed. As a result of the amendments, (i) these agreements are classified as operating leases and (ii) a 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.

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 2025, WES Operating retired the total principal amount outstanding of the 3.950% Senior Notes due 2025 at par value. During the first quarter of 2025, WES Operating retired the total principal amount outstanding of the 3.100% Senior Notes due 2025 at par value. See Debt activity above.

During the third quarter of 2024, WES Operating completed the public offering of $800.0 million in aggregate principal amount of 5.450% Senior Notes due 2034. Net proceeds from the offering were used to repay a portion of the 3.100% and 3.950% Senior Notes due 2025, and for general partnership purposes, including the funding of capital expenditures. In addition, during 2024, WES Operating purchased and retired $150.0 million of certain of its senior notes via open-market repurchases with cash from operations.

As of June 30, 2025, WES Operating was in compliance with all covenants under the relevant governing indentures.

9. DEBT

Revolving credit facility. In April 2025, WES Operating exercised an option to extend the maturity date of the RCF from April 2029 to April 2030, for each extending lender. The non-extending lender’s commitments mature in April 2028 and represent $120.0 million out of $2.0 billion of total commitments, which are expandable to a maximum of $2.5 billion, from all lenders.

As of June 30, 2025, there wereno outstanding borrowings, resulting in $2.0 billion in effective borrowing capacity under the RCF. Any outstanding commercial paper borrowings (see below) reduce the effective borrowing capacity under the RCF as WES Operating maintains availability under the RCF as support for its commercial paper program. As of June 30, 2025 and 2024, the interest rate on any outstanding RCF borrowings was 5.62% and 6.64%, respectively. The facility-fee rate was 0.20% at June 30, 2025 and 2024. As of June 30, 2025, WES Operating was in compliance with all covenants under the RCF.

Commercial paper program. In November 2023, WES Operating entered into an unsecured commercial paper program under which it may issue (and have outstanding at any one time) an aggregate principal amount up to $2.0 billion. WES Operating intends to maintain a minimum aggregate available borrowing capacity under the RCF equal to the aggregate amount of outstanding commercial paper borrowings. The maturities of the notes may vary but may not exceed 397 days. As of June 30, 2025, there wereno outstanding borrowings under the commercial paper program.

10. COMMITMENTS AND CONTINGENCIES

Environmental obligations. The Partnership is subject to various environmental-remediation obligations arising from federal, state, and local regulations regarding air and water quality, hazardous and solid waste disposal, and other environmental matters. As of June 30, 2025, and December 31, 2024, the consolidated balance sheets included $3.5 million and $4.0 million, respectively, of liabilities for remediation and reclamation obligations. The current portion of these amounts is included in Accrued liabilities, and the long-term portion of these amounts is included in Other liabilities. The majority of payments related to these obligations are expected to be made over the next year. See Note 8.

Litigation and legal proceedings. From time to time, the Partnership is involved in legal, tax, regulatory, and other proceedings in various forums regarding performance, contracts, and other matters that arise in the ordinary course of business. Management is not aware of any such proceeding for which the final disposition could have a material adverse effect on the Partnership’s financial condition, results of operations, or cash flows.

Other commitments. The Partnership has payment obligations, or commitments, that include, among other things, a revolving credit facility, other third-party long-term debt, obligations related to the Partnership’s capital spending programs, pipeline and offload commitments, and various operating and finance leases. The payment obligations related to the Partnership’s capital spending programs, the majority of which is expected to be paid in the next 12 months, primarily relate to expansion, construction, and asset-integrity projects at the DBM water systems, West Texas complex, Powder River Basin complex, and DJ Basin complex.

11. REPORTABLE SEGMENT

Segment overview. The Partnership’s chief operating decision maker (“CODM”) is the Partnership’s President and Chief Executive Officer who assesses performance and allocates resources on a consolidated basis due to the similar nature of services provided to customers across the Partnership’s domestic asset portfolio. The CODM does not assess performance and allocate resources separately for Western Midstream Operating, LP. Accordingly, the Partnership has a single operating and reportable segment, all the assets of which are in the United States and gather, compress, treat, process, and transport natural gas; gather, stabilize, and transport condensate, NGLs, and crude oil; and gather and dispose of produced water.

Performance measures. Adjusted EBITDA attributable to Western Midstream Partners, LP (“Adjusted EBITDA”) is used as the performance measure by the Partnership’s CODM in assessing performance and allocating resources to the Partnership’s single operating and reportable segment. Net income (loss) is the most comparable GAAP metric to the performance metric of non-GAAP Adjusted EBITDA. The Partnership defines 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) income tax benefit, (v) other income, and (vi) the noncontrolling interest owners’ proportionate share of revenues and expenses.

Adjusted EBITDA is a non-GAAP financial measure that the CODM utilizes to assess (i) the Partnership’s operating performance as compared to other publicly traded partnerships in the midstream industry, without regard to financing methods, capital structure, or historical cost basis, (ii) the ability of the Partnership’s assets to generate cash flow to make distributions, and (iii) the viability of acquisitions and capital expenditures and the returns on investment of various investment opportunities. The Partnership’s calculation of Adjusted EBITDA may or may not be comparable to similarly titled measures used by others.

11. REPORTABLE SEGMENT

Summarized financial information. The following table presents information about the Partnership’s single operating and reportable segment including (i) total revenues and other, (ii) significant expenses, and (iii) other segment items:

(1)Includes Service revenue - fee based, Service revenue - product based, and Product sales.

(2)The significant expense categories and amounts align with the information that is regularly provided to the CODM.

(3)General and administrative expense as presented in the consolidated statements of operations less non-cash equity-based compensation expense and non-cash amortization of cloud-computing arrangements.

(4)Includes interest income earned on cash and cash equivalent balances.

(5)Other includes: (i) Cost of product, (ii) Non-cash equity-based compensation expense, (iii) non-cash amortization of cloud-computing arrangements, (iv) Property and other taxes, (v) Long-lived asset and other impairments, (vi) Gain (loss) on divestiture and other, net, and (vii) Gain (loss) on early extinguishment of debt.

The CODM uses consolidated total assets as the measure of the Partnership’s single reportable segment assets. As of June 30, 2025, and December 31, 2024, the consolidated balance sheets included $12.2 billion and $13.1 billion, respectively, of total assets, which includes $523.5 million and $541.4 million of assets related to equity investments as of June 30, 2025, and December 31, 2024, respectively.

Capital expenditures for additions to long-lived assets were $321.0 million and $405.7 million for the six months ended June 30, 2025 and 2024, respectively.

12. SUBSEQUENT EVENT

Aris. On August 6, 2025, the Partnership entered into an agreement to acquire Aris Water Solutions Inc. (“Aris”) by merger in an equity-and-cash transaction valued at $1.5 billion, plus Aris’s outstanding debt of $500 million of senior notes. Under the terms of the merger agreement, Aris shareholders may elect to receive 0.625 common units of the Partnership, $25.00 in cash (without interest), or a combination of both, for each share of Aris common stock held, with the cash consideration being subject to proration to ensure that the total cash consideration paid by the Partnership will not exceed $415 million. In the aggregate, the Partnership expects to issue approximately 26.6 million common units and pay approximately $415 million in cash, assuming maximum cash consideration. The Partnership expects to fund the non-equity portion of the transaction with cash on hand, borrowings under the RCF, and/or commercial paper.

Aris’s water infrastructure assets, located in Lea and Eddy Counties, New Mexico and West Texas, include approximately 790 miles of produced-water pipeline,1,800 MBbls/d of produced-water handling capacity,1,400 MBbls/d of water recycling capacity and 625,000 dedicated acres. The merger agreement, which was unanimously approved by the Boards of Directors of Aris and the General Partner, is subject to customary closing conditions, regulatory approvals, and Aris shareholder approval, and is expected to close in the fourth quarter of 2025.
