**WESTERN MIDSTREAM PARTNERS, LP AND WESTERN MIDSTREAM OPERATING, LP**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**(UNAUDITED)**

**1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION**

***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:

**WESTERN MIDSTREAM PARTNERS, LP AND WESTERN MIDSTREAM OPERATING, LP**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**(UNAUDITED)**

**1. 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 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*.

**(UNAUDITED)**

**1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION**

***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**

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:

***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.

***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 repurchased no 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.

**6. RELATED-PARTY TRANSACTIONS**

***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.

**6. RELATED-PARTY TRANSACTIONS**

***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.

***WES Operating Senior Notes.*** In January 2020, WES Operating issued the 4.050% Senior Notes due 2030 and 5.250% Senior Notes due 2050. Including the effects of the issuance prices, underwriting discounts, and interest**-**rate adjustments, the effective interest rates of the Senior Notes due 2030 and 2050, were 4.169% and 5.363%, respectively, at June 30, 2025 and 2024. 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 were no 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 were no 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.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**(UNAUDITED)**

**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.

**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.

**OUTLOOK**

We expect our business to be affected by the below**-**described key trends and uncertainties. Our expectations are based on assumptions made by us and information currently available to us. To the extent our underlying assumptions about, or interpretations of, available information prove incorrect, our actual results may vary materially from expected results.

***Impact of 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. The New York Mercantile Exchange West Texas Intermediate crude**-**oil daily settlement prices during 2024, ranged from a low of $65.75 per barrel in September 2024 to a high of $86.91 per barrel in April 2024, and prices during the six months ended June 30, 2025, ranged from a low of $57.13 per barrel in May 2025 to a high of $80.04 per barrel in January 2025. The Waha Hub natural-gas prices during 2024, ranged from a low of ($6.23) per MMBtu in August 2024 to a high of $8.27 per MMBtu in January 2024, and prices during the six months ended June 30, 2025, ranged from a low of ($1.86) per MMBtu in May 2025 to a high of $7.50 per MMBtu in January 2025. 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 in favorable commodity-price environments, our customers face operational challenges such as severe weather disruptions, oil and gas takeaway constraints, produced water recycling and disposal limitations, seismicity concerns, new regulatory requirements, and optimizing large, complex drilling programs. Our producers' ability to mitigate or manage such challenges can significantly impact 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 tariffs.*** High inflation in the U.S. has raised our costs for steel products, automation components, power supply, labor, materials, fuel, and services, raising operating costs and capital expenditures. Additionally, the Trump administration has imposed significant import tariffs, including on imports of steel and aluminum, and may impose further tariffs on other U.S. trading partners. These tariffs could substantially increase our operating and capital costs. While future inflation and tariff impacts are uncertain, higher operating and capital costs could materially and negatively affect 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.*** Interest rates can be volatile, affecting our interest expense on RCF and commercial paper borrowings. Future increased interest rates would likely 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 may affect investor yield requirements. A rising interest-rate environment could have an adverse impact on our unit price and ability to issue equity to make acquisitions, to reduce debt, or for other purposes. However, we expect our cost of capital to remain competitive, as our peers face similar interest-rate dynamics.

*Natural-gas assets*

Total throughput attributable to WES for natural**-**gas assets increased by 141 MMcf/d for the three months ended June 30, 2025, primarily due to (i) higher volumes at the West Texas, DJ Basin, and Powder River Basin complexes due to increased production in the areas, and (ii) higher volumes at the Mi Vida plant. These increases were offset partially by lower volumes at the Brasada complex and Springfield gas-gathering system due to decreased production in the area and downtime during the second quarter of 2025.

Total throughput attributable to WES for natural**-**gas assets increased by 192 MMcf/d for the six months ended June 30, 2025, primarily due to (i) higher volumes at the West Texas, Powder River Basin, and Chipeta complexes due to increased production in the areas, and (ii) higher volumes on the Red Bluff Express pipeline due to the addition of a new receipt point into the pipeline beginning in November 2024. These increases were offset partially by (i) lower volumes at the Marcellus Interest systems due to the sale of the asset during the second quarter of 2024, (ii) lower volumes at the Brasada complex and Springfield gas-gathering system due to decreased production in the area and downtime during the second quarter of 2025, (iii) lower volumes at the MIGC system due to certain temporary customer constraints, and (iv) lower volumes at the Granger complex due to decreased production in the area.

Service revenues – fee based increased by $99.6 million for the six months ended June 30, 2025, primarily due to increases of (i) $65.6 million at the West Texas complex due to increased throughput, partially offset by decreased deficiency fees on certain contracts with throughput minimums, and (ii) $17.9 million at the DBM oil system, $11.3 million at the Powder River Basin complex, $9.1 million at the DBM water systems, $7.7 million at the DJ Basin complex, and $5.7 million at the Chipeta complex, all primarily due to increased throughput. These increases were offset partially by decreases of (i) $11.0 million at the Marcellus Interest systems due to the sale of the asset during the second quarter of 2024 and (ii) $7.5 million at the Springfield systems primarily due to decreased throughput.

*Other revenues from customers*

Other revenues from customers decreased by $3.0 million for the three months ended June 30, 2025, primarily due to decreased average prices at the DJ Basin complex.

Other revenues from customers decreased by $33.2 million for the six months ended June 30, 2025, primarily due to decreases of (i) $17.0 million at the DJ Basin complex due to decreased volumes sold and (ii) $9.3 million at the Chipeta complex due to contract changes effective during the third quarter of 2024 and decreased product recoveries.

Interest expense increased by $7.4 million for the six months ended June 30, 2025, primarily due to an increase of $22.2 million of interest incurred on the 5.450% Senior Notes due 2034 that were issued during the third quarter of 2024. This increase was offset partially by decreases of (i) $9.1 million due to the repayment of the 3.100% Senior Notes due 2025 during the first quarter of 2025 and (ii) $5.6 million due to lower outstanding borrowings on the commercial paper program during 2025. See *Liquidity and Capital Resources—Debt and credit facilities* within this Item 2.

***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.

**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 recorded as Operation and maintenance expense with an offset recorded as revenue for the reimbursement by certain customers.

***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) income tax benefit, (v) other income, and (vi) 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the ability of our assets to generate cash flow to make distributions; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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 our 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 represents the amount of cash that is available in aggregate for distributions, debt repayments, and other general partnership purposes.

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 (i) should not be considered as alternatives to the comparable GAAP measures or any other measure of financial performance presented in accordance with GAAP, (ii) have important limitations as analytical tools because they exclude some, but not all, items that affect the comparable GAAP measures, (iii) should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP, and (iv) 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 our non-GAAP measures as analytical tools by reviewing the comparable GAAP measures, understanding the differences, 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 reconciliations of the GAAP measure to our non-GAAP measures:

<sup>(1)</sup> Average for period.

***Adjusted Gross Margin.*** Adjusted Gross Margin increased by $18.3 million for the three months ended June 30, 2025, primarily due to increased throughput at the West Texas complex, DBM water systems, and DBM oil system.

Adjusted Gross Margin increased by $58.9 million for the six months ended June 30, 2025, primarily due to (i) increased throughput at the West Texas complex, partially offset by decreased deficiency fees on certain contracts with throughput minimums, and (ii) increased throughput at the DBM oil system, Powder River Basin complex, and DBM water systems. These increases were offset partially by (i) the sale of our interests in the Marcellus Interest systems, Saddlehorn, and Mont Belvieu JV during 2024, and (ii) decreased throughput at the Springfield gas-gathering system.

Per**-**Mcf Adjusted Gross Margin for natural**-**gas assets decreased by $0.02 for the three months ended June 30, 2025, primarily due to (i) lower volumes sold, lower average prices, and contract mix at the West Texas complex, and (ii) lower volumes sold and decreased deficiency fees at the DJ Basin complex.

Per**-**Bbl Adjusted Gross Margin for crude**-**oil and NGLs assets decreased by $0.15 for the three months ended June 30, 2025, primarily due to lower distributions and increased throughput at TEP and FRP, which have a lower-than-average per-Bbl margin as compared to our other crude-oil and NGLs assets. These decreases were offset partially by increased throughput at the DBM 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 $0.15 for the six months ended June 30, 2025, primarily due to (i) lower throughput at TEP and FRP, which have a lower-than-average per-Bbl margin as compared to our other crude oil and NGLs assets and (ii) the sale of our interest in Whitethorn LLC which had a lower-than-average per-Bbl margins as compared to our other crude oil and NGLs assets. These increases were offset partially by decreased revenues associated with demand volumes, partially offset by increased throughput and higher average fees resulting from cost-of-service rate redeterminations effective January 1, 2025, at the DJ Basin oil system.

Per**-**Bbl Adjusted Gross Margin for produced**-**water assets decreased by $0.02 for the six months ended June 30, 2025, primarily due to a change in contract terms effective January 1, 2025.

***Adjusted EBITDA.*** Adjusted EBITDA increased by $24.3 million for the three months ended June 30, 2025, primarily due to a $25.2 million increase in total revenues and other.

Adjusted EBITDA increased by $25.0 million for the six months ended June 30, 2025, primarily due to (i) a $66.1 million increase in total revenues and other and (ii) a $16.0 million decrease in cost of product (net of lower of cost or market inventory adjustments). These amounts were offset partially by (i) a $32.9 million increase in operation and maintenance expenses and (ii) a $15.8 million decrease in distributions from equity investments.

**<u>[**Table of Contents**](#i78f68e9384ed4937a462ea123e13d046_10)</u>**

***Free Cash Flow.*** Free Cash Flow decreased by $11.0 million for the three months ended June 30, 2025, primarily due to (i) a $36.2 million increase in capital expenditures and (ii) an $8.0 million decrease in distributions from equity investments in excess of cumulative earnings. These amounts were offset partially by a $33.2 million increase in net cash provided by operating activities.

Free Cash Flow increased by $138.0 million for the six months ended June 30, 2025, primarily due to (i) an $84.6 million decrease in capital expenditures and (ii) a $63.6 million increase in net cash provided by operating activities. These amounts were offset partially by a $10.3 million decrease in distributions from equity investments in excess of cumulative earnings.

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, acquisitions, and capital expenditures. Our sources of liquidity, as of June 30, 2025, included cash and cash equivalents, cash flows generated from operations, effective borrowing capacity under the RCF, our commercial paper program, 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. We distribute all our available cash, as defined in our partnership agreement, within 55 days following each quarter's end. The Board declared a cash distribution to unitholders for the second quarter of 2025 of $0.910 per unit, or $355.3 million in the aggregate. The cash distribution is payable on August 14, 2025, to our unitholders of record at the close of business on August 1, 2025.

In February 2025, the Board authorized a buyback program of up to $250.0 million of our 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. 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 acquire any common units and the program may be suspended or discontinued at our discretion without prior notice.

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, 2025, we had a $210.2 million working capital surplus, which we define as the amount by which current assets exceed current liabilities. As of June 30, 2025, there was $2.0 billion in effective borrowing capacity under the RCF. Any outstanding commercial paper borrowings reduce the effective borrowing capacity under the RCF as WES Operating maintains availability under the RCF as support for its commercial paper program. See *Note 8—Selected Components of Working Capital* and *Note 9—Debt* in the *Notes to Consolidated Financial Statements* under Part I, Item 1 of this Form 10-Q.

***Capital expenditures*.** Capital expenditures in the consolidated statements of cash flows reflect capital expenditures on a cash basis, when payments are made. Capital incurred is presented on an accrual basis. Acquisitions and capital expenditures as presented in the consolidated statements of cash flows and capital incurred were as follows:

---

| | | |
|:---|:---|:---|
| | **Six Months Ended <br>June 30,** | **Six Months Ended <br>June 30,** |
| *thousands* | **2025** | **2024** |

| Capital expenditures <sup>(1)</sup> | **321025** | 405653 |
| Capital incurred <sup>(1)</sup> | **342094** | 422185 |

---

<u>_________________________________________________________________________________________</u> 

<sup>(1)</sup> For six months ended June 30, 2025 and 2024, included $4.3 million and $7.8 million, respectively, of capitalized interest.

Capital expenditures decreased by $84.6 million for the six months ended June 30, 2025, primarily due to decreases of (i) $137.7 million at the West Texas complex, primarily attributable to construction costs incurred in 2024 associated with the North Loving plant that was completed in the first quarter of 2025, (ii) $16.6 million at the DBM water systems due to decreased construction of certain water**-**disposal wells, equipment, facilities, and well-connect projects, and (iii) $9.9 million in corporate-level capital expenditures. These decreases were offset partially by increases of (i) $37.9 million at the Powder River Basin complex primarily attributable to an increase in construction of facilities and well-connect projects and (ii) $23.7 million at the DBM oil system related to an increase in pipeline 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:

| &nbsp;&nbsp;&nbsp;Investing activities | **(314764)** | 381854 |
| &nbsp;&nbsp;&nbsp;Financing activities | **(1740738)** | (1341648) |
| Net increase (decrease) in cash and cash equivalents | $**(960732)** | $71332 |

---

*Operating activities*. Net cash provided by operating activities increased for the six months ended June 30, 2025, primarily due to higher cash operating income and the impact of changes in assets and liabilities, partially offset by higher interest expense and lower distributions from equity-investment earnings. 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, 2025, primarily included (i) capital expenditures, primarily related to expansion, construction, and asset**-**integrity projects at the West Texas complex, Powder River Basin complex, DBM water systems, DBM oil system, DJ Basin complex, and Chipeta complex, (ii) increases to materials and supplies inventory and other, and (iii) distributions received from equity investments in excess of cumulative earnings.

Net cash provided by investing activities for the six months ended June 30, 2024, primarily included (i) proceeds related to the sale of several equity investments to third parties, (ii) proceeds related to the sale of our 33.75% interest in the Marcellus Interest systems to a third party, (iii) distributions received from equity investments in excess of cumulative earnings, (iv) capital expenditures, primarily related to expansion, construction, and asset**-**integrity projects at the West Texas complex, DBM water systems, DJ Basin complex, Powder River Basin complex, and DBM oil system, and (v) increases to materials and supplies inventory and other.

*Financing activities*. Net cash used in financing activities for the six months ended June 30, 2025, primarily included (i) repayment of the total principal amount outstanding of the 3.950% Senior Notes due 2025 and 3.100% Senior Notes due 2025 at par value, (ii) distributions paid to WES unitholders and noncontrolling interest owners, and (iii) a decrease in outstanding checks.

Net cash used in financing activities for the six months ended June 30, 2024, primarily included (i) net repayments under the commercial paper program, (ii) distributions paid to WES unitholders and noncontrolling interest owners, and (iii) retiring portions of certain of WES Operating's senior notes via open-market repurchases.

***Debt and credit facilities.*** As of June 30, 2025, the carrying value of outstanding debt was $6.9 billion. In addition, we have no borrowings due within the next year and, as of June 30, 2025, we have $2.0 billion in effective borrowing capacity under WES Operating's $2.0 billion RCF. Any outstanding commercial paper borrowings reduce the effective borrowing capacity under the RCF as WES Operating maintains availability under the RCF as support for its commercial paper program.

During the six months ended June 30, 2025, WES Operating (i) retired the 3.950% Senior Notes due 2025 on the maturity date of June 1, 2025, for 336.8 million and (ii) retired the 3.100% Senior Notes due 2025 on the maturity date of February 3, 2025, for $663.8 million. WES Operating repaid the 3.950% Senior Notes due 2025 and 3.100% Senior Notes due 2025 with cash on hand, including proceeds received from the 2024 public offering of $800.0 million in aggregate principal amount of 5.450% Senior Notes due 2034.

For additional information on our senior notes, RCF, and commercial paper program, see *Note 9—Debt* in the *Notes to Consolidated Financial Statements* under Part I, Item 1 of this Form 10-Q.

**<u>[**Table of Contents**](#i78f68e9384ed4937a462ea123e13d046_10)</u>**

***Credit risk****.* We bear credit risk through exposure to non**-**payment or non**-**performance by our counterparties (e.g., Occidental and other customers, financial institutions, and other parties), including risks 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 contractual rights to request adequate assurance of performance.

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 6—Related-Party Transactions* in the *Notes to Consolidated Financial Statements* under Part I, Item 1 of this Form 10-Q.

Our ability to make cash distributions to our unitholders may be adversely impacted if Occidental becomes unable to perform under the terms of gathering, processing, transportation, and disposal agreements.

**ITEMS AFFECTING THE COMPARABILITY OF FINANCIAL RESULTS WITH WES OPERATING**

<sup>(1)</sup> Represents general and administrative expenses incurred by WES separate from, and in addition to, those incurred by WES Operating.

<sup>(2)</sup> Represents distributions to WES common unitholders paid under WES's partnership agreement. See *Note 4—Partnership Distributions* and *Note 5—Equity and Partners' Capital* in the *Notes to Consolidated Financial Statements* under Part I, Item 1 of this Form 10-Q.

<sup>(3)</sup> Difference attributable to elimination in consolidation of WES Operating's distributions on partnership interests owned by WES. See *Note 4—Partnership Distributions* and *Note 5—Equity and Partners' Capital* in the *Notes to Consolidated Financial Statements* under Part I, Item 1 of this Form 10-Q.

***Noncontrolling interest.*** WES Operating's noncontrolling interest consists of the 25% third**-**party interest in Chipeta.

***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 4—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, 2024.

**RECENT ACCOUNTING DEVELOPMENTS** 

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.

**<u>[**Table of Contents**](#i78f68e9384ed4937a462ea123e13d046_10)</u>**

**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, 2024, except as noted below and in *Outlook* under Part I, Item 2 of this Form 10-Q.

For the six months ended June 30, 2025, 97% 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 lowered its target range for the federal funds rate three times in 2024, and the target range has remained static during the six months ended June 30, 2025. Any future increases in the federal funds rate likely will result in an increase in financing costs. As of June 30, 2025, WES Operating had (i) 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 and (ii) no outstanding commercial paper borrowings. While a 10% change in the applicable benchmark interest rate would not materially impact interest expense on our outstanding borrowings at June 30, 2025, it would impact the fair value of the senior notes.

Additional short-term or variable**-**rate debt may be issued in the future, either under the RCF or other financing sources, including commercial paper borrowings or debt issuances.

**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 9A, "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, 2025.

***Changes in Internal Control Over Financial Reporting*.** There were no changes in WES's or WES Operating's internal control over financial reporting during the quarter ended June 30, 2025, that have materially affected, or are reasonably likely to materially affect, WES's or WES Operating's internal control over financial reporting.

**PART II. OTHER INFORMATION**

**Item 1. Legal Proceedings** 

We have elected to use a $1.0 million threshold for disclosing certain proceedings arising under federal, state, or local environmental laws when a government authority is a party and potential monetary sanctions are involved. We believe proceedings under this threshold are not material to our business and financial proceedings.

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.

&nbsp;&nbsp;&nbsp;&nbsp;

**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, 2024, together with all of the other information included in this document, and in our other public filings, press releases, and public discussions with management.

**Item 2. Unregistered Sales of Equity Securities and Use of Proceeds**

The following table sets forth information with respect to repurchases made by WES of its common units in the open market or in privately negotiated transactions under the 2025 Purchase Program during the second quarter of 2025:

**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, 2025, none of our executive officers or directors adopted or terminated a Rule 10b5-1 trading arrangement (as defined in Item 408(a)(1)(i) of Regulation S-K) or adopted or terminated a non-Rule 10b5-1 trading arrangement (as defined in Item 408(c) of Regulation S-K).
