1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

General. Western Midstream Partners, LP 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. Western Midstream Partners, LP 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.
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. “Anadarko” refers to Anadarko Petroleum Corporation and its subsidiaries, excluding Western Midstream Holdings, LLC. Anadarko became a wholly owned subsidiary of Occidental as a result of Occidental’s acquisition by merger of Anadarko on August 8, 2019. “Related parties” refers to Occidental (see Note 6), the Partnership’s investments accounted for under the equity method of accounting (see Note 7), and the Partnership and WES Operating for transactions 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 natural gas, NGLs, and condensate on behalf of itself and its customers under certain contracts.

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 financial interest, including WES Operating, WES Operating GP, proportionately consolidated interests, and equity investments (see table below). All significant intercompany transactions have been eliminated.
The following table outlines the ownership interests and the accounting method of consolidation used in the consolidated financial statements for entities not wholly owned (see Note 7):
Percentage Interest

Texas Express Pipeline LLC (“TEP”)20.00 %
Texas Express Gathering LLC (“TEG”)20.00 %
White Cliffs Pipeline, LLC (“White Cliffs”)10.00 %
_________________________________________________________________________________________
(1)The 25% third-party interest in Chipeta Processing LLC (“Chipeta”) is reflected within noncontrolling interests in the consolidated financial statements. See Noncontrolling interests below.
(2)The Partnership proportionately consolidates its associated share of the assets, liabilities, revenues, and expenses attributable to this asset.
(3)Investments in non-controlled entities over which the Partnership exercises significant influence are accounted for under the equity method of accounting. “Equity-investment throughput” refers to the Partnership’s share of average throughput for these investments.

Certain information and note disclosures commonly included in annual financial statements have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, the accompanying consolidated financial statements and notes should be read in conjunction with the Partnership’s 2023 Form 10-K, as filed with the SEC on February 21, 2024. Management believes that the disclosures made are adequate to make the information not misleading.
The consolidated financial results of WES Operating are included in the Partnership’s consolidated financial statements. Throughout these notes to consolidated financial statements, and to the extent material, any differences between the consolidated financial results of the Partnership and WES Operating are discussed separately. The Partnership’s consolidated financial statements differ from those of WES Operating primarily as a result of (i) the presentation of noncontrolling interest ownership (see Noncontrolling interests below), (ii) the elimination of WES Operating GP’s investment in WES Operating with WES Operating GP’s underlying capital account, (iii) the general and administrative expenses incurred by the Partnership, which are separate from, and in addition to, those incurred by WES Operating, (iv) the inclusion of the impact of Partnership equity balances and Partnership distributions, and (v) transactions between the Partnership and WES Operating that eliminate upon consolidation.

WESTERN MIDSTREAM PARTNERS, LP AND WESTERN MIDSTREAM OPERATING, LP
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)
1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

Presentation of the Partnership’s assets. The Partnership’s assets include assets owned and ownership interests accounted for by the Partnership under the equity method of accounting, through its 98.0% partnership interest in WES Operating, as of September 30, 2024 (see Note 7). The Partnership also owns and controls the entire non-economic general partner interest in WES Operating GP, and the Partnership’s general partner is owned by Occidental.

Use of estimates. In preparing financial statements in accordance with GAAP, management makes informed judgments and estimates that affect the reported amounts of assets, liabilities, revenues, and expenses. Management evaluates its estimates and related assumptions regularly, using historical experience and other reasonable methods. Changes in facts and circumstances or additional information may result in revised estimates, and actual results may differ from these estimates. Effects on the business, financial condition, and results of operations resulting from revisions to estimates are recognized when the facts that give rise to the revisions become known. The information included herein reflects all normal recurring adjustments which are, in the opinion of management, necessary for a fair presentation of the consolidated financial statements.

Noncontrolling interests. The Partnership’s noncontrolling interests in the consolidated financial statements consist of (i) the 25% third-party interest in Chipeta and (ii) the 2.0% limited partner interest in WES Operating owned by an Occidental subsidiary. WES Operating’s noncontrolling interest in the consolidated financial statements consists of the 25% third-party interest in Chipeta. See Note 5.

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.
In November 2023, the Financial Accounting Standards Board issued Accounting Standards Update 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” The standard improves reportable segment disclosure requirements for public business entities primarily through enhanced disclosures about significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit (referred to as the “significant expense principle”). The standard will become effective for the Partnership for the fiscal year 2024 annual financial statements and interim financial statements thereafter and will be applied retrospectively for all prior periods presented in the financial statements, with early adoption permitted. The Partnership plans to adopt the standard when it becomes effective beginning with the fiscal year 2024 annual financial statements. The Partnership is currently evaluating the impact this guidance will have on disclosures in the Notes to Consolidated Financial Statements. This standard will have no impact on the Partnership’s financial statements, but will result in additional disclosure.

Equity-based compensation. During the nine months ended September 30, 2024 and 2023, the Partnership issued 1,035,444 and 832,707 common units, respectively, under its long-term incentive plans. Compensation expense was $8.8 million and $28.6 million for the three and nine months ended September 30, 2024, respectively, and $7.2 million and $22.0 million for the three and nine months ended September 30, 2023, respectively.

Transaction price allocated to remaining performance obligations. Revenues expected to be recognized from certain performance obligations that are unsatisfied (or partially unsatisfied) as of September 30, 2024, 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 (the “Mont Belvieu JV”), (ii) the 20.00% interest in Whitethorn Pipeline Company LLC (“Whitethorn LLC”), (iii) the 15.00% interest in Panola Pipeline Company, LLC (“Panola”), and (iv) the 20.00% interest in Saddlehorn Pipeline Company, LLC (“Saddlehorn”). 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.

Meritage. On October 13, 2023, the Partnership closed on the acquisition of Meritage Midstream Services II, LLC (“Meritage”) for $885.0 million (subject to certain customary post-closing adjustments) funded with cash, including proceeds from the Partnership’s $600.0 million senior note issuance in September 2023 (see Note 10) and borrowings on the senior unsecured revolving credit facility (“RCF”). The cash purchase price, adjusted for working capital and certain customary post-closing adjustments and reduced by the $38.4 million of cash acquired (as presented in the table below), was $878.2 million.
The assets acquired, located in Converse, Campbell, and Johnson counties, Wyoming, include approximately 1,500 miles of high- and low-pressure natural-gas gathering pipelines, approximately 380 MMcf/d of natural-gas processing capacity, and the Thunder Creek NGL pipeline, which is a 120 mile, 38 MBbls/d FERC-regulated NGL pipeline that connects to the processing facility. The acquisition expands the Partnership’s existing Powder River Basin asset base, increasing total natural-gas processing capacity in that region to 440 MMcf/d.
The Meritage acquisition has been accounted for under the acquisition method of accounting. The assets acquired and liabilities assumed in the Meritage acquisition were recorded in the consolidated balance sheet at their estimated fair values as of the acquisition date. Results of operations attributable to the Meritage acquisition were included in the Partnership’s consolidated statements of operations beginning on the acquisition date in the fourth quarter of 2023.

4. PARTNERSHIP DISTRIBUTIONS

Partnership distributions. Under its partnership agreement, the Partnership distributes all of its available cash to unitholders of record on the applicable record date within 55 days following each quarter’s end. The amount of available cash (beyond proper reserves as defined in the partnership agreement) generally is all cash on hand at the end of the quarter, plus, at the discretion of the general partner, working capital borrowings made subsequent to the end of such quarter, less the amount of cash reserves established by the general partner to provide for the proper conduct of the Partnership’s business, including (i) to fund future capital expenditures; (ii) to comply with applicable laws, debt instruments, or other agreements; or (iii) to provide funds for unitholder distributions for any one or more of the next four quarters. Working capital borrowings generally include borrowings made under a credit facility or similar financing arrangement and are intended to be repaid or refinanced within 12 months. In all cases, working capital borrowings are used solely for working capital purposes or to fund unitholder distributions.

To facilitate the distribution of available cash, during 2022 the Partnership adopted a financial policy that provided for an additional distribution (“Enhanced Distribution”) to be paid in conjunction with the regular first-quarter distribution of the following year (beginning in 2023), in a target amount equal to Free cash flow generated in the prior year after subtracting Free cash flow used for the prior year’s debt repayments, regular-quarter distributions, and unit repurchases. In April 2023, the Board approved an Enhanced Distribution of $0.356 per unit, or $140.1 million, related to the Partnership’s 2022 performance, which was paid in conjunction with the regular first-quarter 2023 distribution on May 15, 2023.

WES Operating partnership distributions. WES Operating makes quarterly cash distributions to the Partnership and WGR Asset Holding Company LLC (“WGRAH”), a subsidiary of Occidental, in proportion to their share of limited partner interests in WES Operating.

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 September 30, 2024, Occidental held 165,681,578 common units, representing a 42.5% 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 214,873,849 common units, representing a 55.2% limited partner interest in the Partnership.
In August 2024, affiliates of Occidental sold 19,500,000 of the Partnership’s common units it held through an underwritten offering. The Partnership did not receive any proceeds from the public offering.

Partnership equity repurchases. In 2022, the Board authorized the Partnership to buy back up to $1.25 billion of the Partnership’s common units through December 31, 2024 (the “$1.25 billion Purchase Program”). The common units may be purchased from time to time in the open market at prevailing market prices or in privately negotiated transactions. During the nine months ended September 30, 2024, there were no common units repurchased. During the nine months ended September 30, 2023, the Partnership repurchased 5,387,322 common units, which included 5,100,000 common units repurchased from Occidental, for an aggregate purchase price of $134.6 million. The units were canceled immediately upon receipt. As of September 30, 2024, the Partnership had an authorized amount of $627.8 million remaining under the program.

Holdings of WES Operating equity. As of September 30, 2024, (i) the Partnership, directly and indirectly through its ownership of WES Operating GP, owned a 98.0% limited partner interest and the entire non-economic general partner interest in WES Operating and (ii) Occidental, through its ownership of WGRAH, owned a 2.0% limited partner interest in WES Operating, which is reflected as a noncontrolling interest within the consolidated financial statements of the Partnership (see Note 1).

Partnership’s net income (loss) per common unit. The common and general partner unitholders’ allocation of net income (loss) attributable to the Partnership was equal to their cash distributions plus their respective allocations of undistributed earnings or losses in accordance with their weighted-average ownership percentage during each period using the two-class method.
The Partnership’s basic net income (loss) per common unit is calculated by dividing the limited partners’ interest in net income (loss) by the weighted-average number of common units outstanding during the period. Diluted net income (loss) per common unit includes the effect of outstanding units issued under the Partnership’s long-term incentive plans.

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, processing, and produced-water disposal arrangements with affiliates of Occidental on most of its systems. While Occidental is the contracting counterparty of the Partnership, these arrangements with Occidental include not just Occidental-produced volumes, but also, in some instances, the volumes of other working-interest owners of Occidental who rely on the Partnership’s facilities and infrastructure to bring their volumes to market. Natural-gas throughput (excluding equity-investment throughput) attributable to production owned or controlled by Occidental was 36% and 34% for the three and nine months ended September 30, 2024, respectively, and 34% for both the three and nine months ended September 30, 2023. Crude-oil and NGLs throughput (excluding equity-investment throughput) attributable to production owned or controlled by Occidental was 92% and 90% for the three and nine months ended September 30, 2024, respectively, and 87% for both the three and nine months ended September 30, 2023. Produced-water throughput attributable to production owned or controlled by Occidental was 78% and 77% for the three and nine months ended September 30, 2024, respectively, and 77% and 78% for the three and nine months ended September 30, 2023, respectively.
The Partnership is currently discussing varying interpretations of certain contractual provisions with Occidental regarding the calculation of the cost-of-service rates under an oil-gathering contract related to the Partnership’s DJ Basin oil-gathering system. If such discussions are resolved in a manner adverse to the Partnership, such resolution could have a negative impact on the Partnership’s financial condition and results of operations, including a reduction in rates and a non-cash charge to earnings.

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.

Related-party expenses. Operation and maintenance expense includes amounts accrued for or paid to related parties for field-related costs, shared field offices, and easements (see Related-party commercial agreement below) supporting the Partnership’s operations at certain assets. 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, by and among Occidental, Anadarko, and WES Operating GP (“Services Agreement”). Most of the administrative and operational services previously provided by Occidental fully transitioned to the Partnership by December 31, 2021, with certain limited transition services remaining in place pursuant to the terms of the Services Agreement.

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 certain wholly owned subsidiaries of the Partnership entered into a Commercial Understanding Agreement (“CUA”). Under the CUA, certain West Texas surface-use and salt-water disposal agreements were amended to reduce usage fees owed by the Partnership in exchange for the forgiveness of certain deficiency fees owed by Occidental and other unrelated contractual amendments. The present value of the reduced usage fees under the CUA was $30.0 million at the time the agreement was executed. Also, as a result of the amendments under the CUA, these agreements are classified as operating leases and a $30.0 million right-of-use (“ROU”) asset, included in Other assets on the consolidated balance sheets, was recognized during the first quarter of 2021. The ROU asset is being amortized to Operation and maintenance expense through 2038, the remaining term of the agreements.

Customer concentration. Occidental was the only customer from which revenues exceeded 10% of consolidated revenues for all periods presented in the consolidated statements of operations.

“Assets under construction” represents property that is not yet placed into productive service as of the respective balance sheet date and is excluded from capitalized costs being depreciated.

Long-lived asset impairments. During the nine months ended September 30, 2023, the Partnership recognized a long-lived asset impairment of $52.1 million for assets located in the Rockies due to a reduction in estimated future cash flows resulting from a contract termination notice received in the first quarter of 2023. This asset was impaired to its estimated fair value of $22.8 million. The fair value was measured using the income approach and Level-3 fair value inputs. The income approach was based on the Partnership’s projected future EBITDA and free cash flows, which requires significant assumptions including, among others, future throughput volumes based on current expectations of producer activity and operating costs.

WES Operating Senior Notes. WES Operating issued the Fixed-Rate 3.100% Senior Notes due 2025, 4.050% Senior Notes due 2030, 5.250% Senior Notes due 2050, and the Floating-Rate Senior Notes due 2023 in January 2020. Including the effects of the issuance prices, underwriting discounts, and interest-rate adjustments, the effective interest rates of the Senior Notes due 2025, 2030, and 2050, were 3.290%, 4.169%, and 5.363%, respectively, at September 30, 2024 and 2023. The effective interest rate of these notes is subject to adjustment from time to time due to a change in credit rating.
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. Interest is payable semi-annually on May 15th and November 15th of each year, with the initial interest payment being due on May 15, 2025. Net proceeds from the offering will be used to repay a portion of the maturing 3.100% Senior Notes due 2025 and 3.950% Senior Notes due 2025 and for general partnership purposes, including the funding of capital expenditures.
During the nine months ended September 30, 2024, WES Operating purchased and retired $150.0 million of certain of its senior notes via open-market repurchases with cash from operations (see Debt activity above) and a gain of $5.4 million was recognized for the early retirement of portions of these notes. As of September 30, 2024, the 3.100% Senior Notes due 2025 and 3.950% Senior Notes due 2025 were classified as short-term debt on the consolidated balance sheet.
During the third quarter of 2023, WES Operating completed the public offering of $600.0 million in aggregate principal amount of 6.350% Senior Notes due 2029. Net proceeds from the offering were used to fund a portion of the aggregate purchase price for the Meritage acquisition (see Note 3), to pay related costs and expenses, and for general partnership purposes. During the second quarter of 2023, WES Operating completed the public offering of $750.0 million in aggregate principal amount of 6.150% Senior Notes due 2033. Net proceeds from the offering were used to repay borrowings under the RCF and for general partnership purposes. In addition, during 2023, WES Operating purchased and retired $276.7 million of certain of its senior notes via open-market repurchases and redeemed the total principal amount outstanding on the Floating-Rate Senior Notes due 2023 at par value with cash on hand. For the three and nine months ended September 30, 2023, a gain of $8.6 million and $15.4 million, respectively, was recognized for the early retirement of portions of these notes.
As of September 30, 2024, WES Operating was in compliance with all covenants under the relevant governing indentures.

Revolving credit facility. In May 2024, WES Operating entered into an amendment to the RCF to exercise an option to extend the maturity date of the RCF from April 2028 to April 2029, 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 from all lenders.
In April 2023, WES Operating (i) repaid all then-outstanding borrowings under its RCF with proceeds from the 6.150% Senior Notes due 2033 offering and (ii) entered into an amendment to its RCF to, among other things, extend the maturity date to April 2028 and provide for a maximum borrowing capacity up to $2.0 billion, expandable to a maximum of $2.5 billion, through the maturity date.
As of September 30, 2024, there were no outstanding borrowings and no outstanding letters of credit, 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 September 30, 2024 and 2023, the interest rate on any outstanding RCF borrowings was 6.15% and 6.62%, respectively. The facility-fee rate was 0.20% at September 30, 2024 and 2023. As of September 30, 2024, 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 September 30, 2024, there were no outstanding borrowings under the commercial paper program.

As of September 30, 2024 and December 31, 2023, the consolidated balance sheets included $2.3 million and $7.3 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 9.

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.

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 (“NYMEX”) West Texas Intermediate crude-oil daily settlement prices during 2023 ranged from a low of $66.74 per barrel in March 2023 to a high of $93.68 per barrel in September 2023, and prices during the nine months ended September 30, 2024, ranged from a low of $65.75 per barrel in September 2024 to a high of $86.91 per barrel in April 2024. The Waha Hub natural gas price during 2023 ranged from a low of ($3.8400) per MMBtu in January 2023 to a high of $3.2750 per MMBtu in January 2023, and prices during the nine months ended September 30, 2024, ranged from a low of ($6.2250) per MMBtu in August 2024 to a high of $8.2650 per MMBtu in January 2024. The extent and duration of commodity-price volatility, and the associated direct and indirect impact on our business, cannot be predicted. To address the risks posed by fluctuating commodity prices, we intend to continue evaluating the relevant price environments and adjust our capital spending plans to reflect our customers’ anticipated activity levels, while maintaining appropriate liquidity and financial flexibility.
Additionally, even when the commodity-price environments are favorable, our customers must manage numerous operational challenges, including severe weather disruptions, downstream and produced-water takeaway constraints, seismicity concerns, new regulatory requirements, and the ability to optimize the efficiency and results of large, complex drilling programs. Our producers’ ability to mitigate or manage such challenges can have a significant impact on the volumes available for us to service in the short term. For this reason, we strive to work proactively with our customers whenever possible to provide high levels of reliability on our systems and help them meet these operational challenges as they arise.

Impact of inflation and supply-chain disruptions. Although somewhat abated during 2024, the U.S. economy has recently experienced significant inflation relative to historical precedent. Inflation has raised our costs for steel products, automation components, power supply, labor, materials, fuel, and services, which has increased our operating costs and capital expenditures. Any increases in inflationary pressure could materially and negatively impact our financial results. To the extent permitted by regulations and escalation provisions in certain of our existing agreements, we have the ability to recover a portion of increased costs in the form of higher fees.

Impact of interest rates. Short- and long-term interest rates can be volatile, resulting in immediate changes to interest expense on RCF borrowings and commercial paper borrowings. Any future increases in interest rates likely will result in additional increases in financing costs. As with other yield-oriented securities, our unit price could be impacted by our implied distribution yield relative to market interest rates. Therefore, changes in interest rates, either positive or negative, may affect the yield requirements of investors who invest in our units, and a rising interest-rate environment could have an adverse impact on our unit price and our ability to issue additional equity, or increase the cost of issuing equity, to make acquisitions, to reduce debt, or for other purposes. However, we expect our cost of capital to remain competitive, as our peers face similar interest-rate dynamics.

ACQUISITIONS AND DIVESTITURES

Marcellus Interest systems. During the second quarter of 2024, we closed on the sale of our 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, we closed on the sale of the following equity investments to third parties: (i) the 25.00% interest in Mont Belvieu JV, (ii) the 20.00% interest in Whitethorn LLC, (iii) the 15.00% interest in Panola, and (iv) the 20.00% interest in Saddlehorn. 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. The sale of the interests in Mont Belvieu JV and Whitethorn LLC also resolved outstanding legal proceedings associated with those assets.

Natural-gas assets
Total throughput attributable to WES for natural-gas assets increased by 28 MMcf/d for the three months ended September 30, 2024, primarily due to higher volumes at the Powder River Basin, West Texas, and Chipeta complexes due to increased production in the areas. These increases were offset partially by (i) lower volumes at the DJ Basin complex due to decreased production in the area and scheduled plant maintenance during the third quarter of 2024, (ii) lower volumes at the MIGC system due to certain temporary customer constraints, (iii) lower volumes at the Marcellus Interest systems due to the sale of the asset during the second quarter of 2024, and (iv) lower volumes at the Springfield gas-gathering system and Mi Vida plant.
Total throughput attributable to WES for natural-gas assets increased by 715 MMcf/d for the nine months ended September 30, 2024, primarily due to (i) higher volumes at the Powder River Basin complex due to the Meritage acquisition, (ii) higher volumes at the West Texas and DJ Basin complexes due to increased production in the areas, (iii) higher volumes at the Red Bluff Express pipeline due to the addition of a new receipt point into the pipeline, (iv) higher volumes at the Springfield gas-gathering system due to new third-party production, and (v) higher volumes at the Brasada plant. These increases were offset partially by (i) lower volumes at the Granger complex due to a contract expiration in the fourth quarter of 2023 and (ii) lower volumes at the Marcellus Interest systems due to the sale of the asset during the second quarter of 2024.

Crude-oil and NGLs assets
Total throughput attributable to WES for crude-oil and NGLs assets decreased by 9 MBbls/d for the three months ended September 30, 2024, primarily due to (i) lower volumes at the DJ Basin oil system due to production declines in the surrounding areas, (ii) the divestiture of Wamsutter in the third quarter of 2024, and (iii) decreased volumes on the White Cliffs pipeline. These decreases were offset partially by higher volumes at the DBM oil system due to increased production in the area.
Total throughput attributable to WES for crude-oil and NGLs assets decreased by 106 MBbls/d for the nine months ended September 30, 2024, primarily due to the divestiture of Whitethorn LLC, Mont Belvieu JV, and Saddlehorn in the first quarter of 2024. These decreases were offset partially by (i) higher volumes at the DBM and DJ Basin oil systems due to increased production in the area and (ii) higher volumes at the Thunder Creek NGL pipeline, which was acquired as part of the Meritage acquisition.

Produced-water assets
Total throughput attributable to WES for produced-water assets increased by 19 MBbls/d and 108 MBbls/d for the three and nine months ended September 30, 2024, respectively, due to higher production.

Service revenues – fee based
Service revenues – fee based increased by $20.5 million for the three months ended September 30, 2024, primarily due to (i) $8.4 million at the West Texas complex as a result of increased throughput, partially offset by decreased electricity-related rates billed to customers and deficiency fees, (ii) $5.8 million at the DJ Basin complex as a result of increased electricity-related rates billed to customers, (iii) $3.7 million and $2.3 million at the Powder River Basin complex and DBM oil system, respectively, primarily due to increased throughput, and (iv) $3.1 million at the Chipeta complex primarily due to new and amended contracts effective July 2024. These increases were offset partially by a decrease of $2.0 million at the Springfield system primarily due to decreased throughput.
Service revenues – fee based increased by $384.4 million for the nine months ended September 30, 2024, primarily due to increases of (i) $135.3 million at the West Texas complex, the majority of which is due to increased throughput, and also due to a higher average fee resulting from a cost-of-service rate redetermination effective January 1, 2024, and increased deficiency fees on certain contracts with increasing throughput minimums, (ii) $132.9 million at the Powder River Basin complex attributable to the acquisition of Meritage, (iii) $64.7 million at the DJ Basin complex primarily due to increased throughput, (iv) $64.3 million and $25.2 million at the DBM water and DBM oil systems, respectively, as a result of increased throughput and a higher average fee resulting from a cost-of-service rate redetermination effective January 1, 2024, and (v) $4.8 million at the Chipeta complex primarily due to new and amended contracts effective July 2024. These increases were offset partially by decreases of (i) $13.0 million at the Marcellus Interest systems due to the sale of the asset during the second quarter of 2024, (ii) $11.6 million at the Brasada complex due to a change in contract terms effective July 1, 2023, partially offset by increased throughput, (iii) $8.8 million at the Granger complex due to a contract expiration in the fourth quarter of 2023, and (iv) $6.0 million and $3.0 million at the Springfield and DJ Basin oil systems, respectively, primarily due to 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, 2024.

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. For the three and nine months ended September 30, 2024, the variance from the federal statutory rate was primarily impacted by a state margin tax rate increase associated with no longer being included in Occidental’s affiliated group tax return beginning in September 2024 due to Occidental’s sale of 19.5 million WES common units in August 2024 and the resulting decrease in WES ownership, inclusive of its ownership in WES Operating.

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) interest income, (v) income tax benefit, (vi) other income, and (vii) the noncontrolling interest owners’ proportionate share of revenues and expenses. We believe the presentation of Adjusted EBITDA provides information useful to investors in assessing our financial condition and results of operations and that Adjusted EBITDA is a widely accepted financial indicator of a company’s ability to incur and service debt, fund capital expenditures, and make distributions. Adjusted EBITDA is a supplemental financial measure that management and external users of our consolidated financial statements, such as industry analysts, investors, commercial banks, and rating agencies, use, among other measures, to assess the following:
our operating performance as compared to other publicly traded partnerships in the midstream industry, without regard to financing methods, capital structure, or historical cost basis;
the ability of our assets to generate cash flow to make distributions; and
the viability of acquisitions and capital expenditures and the returns on investment of various investment opportunities.

Free cash flow. We define “Free cash flow” as net cash provided by operating activities less total capital expenditures and contributions to equity investments, plus distributions from equity investments in excess of cumulative earnings. Management considers Free cash flow an appropriate metric for assessing capital discipline, cost efficiency, and balance-sheet strength. Although Free cash flow is the metric used to assess 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.

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

Adjusted gross margin. Adjusted gross margin decreased by $8.4 million for the three months ended September 30, 2024, primarily due to (i) lower average prices and decreased product recoveries, partially offset by increased throughput at the West Texas complex, and (ii) a decrease in distributions from FRP. These decreases were offset partially by increased throughput at the DBM oil system.
Adjusted gross margin increased by $363.9 million for the nine months ended September 30, 2024, primarily due to (i) increased throughput at the Powder River Basin complex attributable to the acquisition of Meritage, (ii) increased throughput and a higher average fee resulting from a cost-of-service rate redetermination effective January 1, 2024, at the West Texas complex, DBM water systems, and DBM oil system, and (iii) increased throughput at the DJ Basin complex. These increases were offset partially by (i) decreased distributions from TEP, (ii) the sale of our interests in the Mont Belvieu JV, Marcellus Interest systems, and Saddlehorn during 2024, and (iii) decreased processing fees at the Brasada complex resulting from a change in contract terms effective July 1, 2023, partially offset by increased throughput.
Per-Mcf Adjusted gross margin for natural-gas assets decreased by $0.04 for the three months ended September 30, 2024, primarily due to (i) decreased product recoveries and average prices, partially offset by increased throughput at the West Texas complex, which has a higher-than-average per-Mcf margin as compared to our other natural-gas assets, and (ii) increased throughput at the Powder River Basin complex, which has a lower-than-average per-Mcf margin as compared to our other natural-gas assets.
Per-Mcf Adjusted gross margin for natural-gas assets increased by $0.04 for the nine months ended September 30, 2024, primarily due to (i) increased throughput at the West Texas complex, which has a higher-than-average per-Mcf margin as compared to our other natural-gas assets, in addition to a higher average fee resulting from a cost-of-service rate redetermination effective January 1, 2024, and increased deficiency fees on certain contracts with increasing throughput minimums, and (ii) increased throughput at the DJ Basin complex, which has a higher-than-average per-Mcf margin as compared to our other natural-gas assets.
Per-Bbl Adjusted gross margin for crude-oil and NGLs assets decreased by $0.08 for the three months ended September 30, 2024, primarily due to decreased distributions at FRP and TEP, partially offset by increased throughput at the DBM oil system, which has a higher-than-average per-Mcf margin as compared to our other crude-oil and NGLs assets.
Per-Bbl Adjusted gross margin for crude-oil and NGLs assets increased by $0.43 for the nine months ended September 30, 2024, primarily due to (i) the sale of our interests in the Mont Belvieu JV, Saddlehorn, and Whitethorn LLC in the first quarter of 2024, all of which had lower-than-average per-Bbl margins as compared to our other crude-oil and NGLs assets, and (ii) increased throughput at the DBM oil system, which has a higher-than-average per-Mcf margin as compared to our other crude-oil and NGLs assets, in addition to a higher average fee resulting from a cost-of-service rate redetermination effective January 1, 2024. These increases were offset partially by (i) decreased distributions at TEP and (ii) decreased revenues associated with demand volumes at the DJ Basin oil system.
Per-Bbl Adjusted gross margin for produced-water assets increased by $0.13 for the nine months ended September 30, 2024, primarily due to higher throughput and a higher average fee resulting from a cost-of-service rate redetermination effective January 1, 2024.

Adjusted EBITDA. Adjusted EBITDA decreased by $11.2 million for the three months ended September 30, 2024, primarily due to (i) a $22.3 million decrease in total revenues and other, (ii) a $7.7 million increase in operation and maintenance expenses, (iii) a $3.6 million decrease in distributions from equity investments, and (iv) a $3.4 million increase in general and administrative expenses excluding non-cash equity-based compensation expense. These amounts were offset partially by (i) a $21.2 million decrease in cost of product (net of lower of cost or market inventory adjustments) and (ii) a $4.8 million decrease in property and other taxes.
Adjusted EBITDA increased by $255.4 million for the nine months ended September 30, 2024, primarily due to a $428.5 million increase in total revenues and other. This was offset partially by (i) an $87.2 million increase in operation and maintenance expenses, (ii) a $37.0 million decrease in distributions from equity investments, (iii) a $29.4 million increase in general and administrative expenses excluding non-cash equity-based compensation expense, (iv) a $9.3 million increase in cost of product (net of lower of cost or market inventory adjustments), and (v) a $4.0 million increase in property and other taxes.

Free cash flow. Free cash flow decreased by $59.7 million for the three months ended September 30, 2024, primarily due to (i) an $80.1 million decrease in net cash provided by operating activities and (ii) a $2.0 million decrease in distributions from equity investments in excess of cumulative earnings. These decreases were offset partially by a $22.4 million decrease in capital expenditures.
Free cash flow increased by $332.7 million for the nine months ended September 30, 2024, primarily due to a $394.4 million increase in net cash provided by operating activities, partially offset by (i) a $58.7 million increase in capital expenditures and (ii) a $4.2 million decrease in distributions from equity investments in excess of cumulative earnings.

LIQUIDITY AND CAPITAL RESOURCES

Our primary cash uses include equity and debt service, operating expenses, and capital expenditures. Our sources of liquidity, as of September 30, 2024, 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. Under our partnership agreement, we distribute all of our available cash (beyond proper reserves as defined in our partnership agreement) within 55 days following each quarter’s end. Our cash flow and resulting ability to make cash distributions are dependent on our ability to generate cash flow from operations. Generally, our available cash is our cash on hand at the end of a quarter after the payment of our expenses and the establishment of cash reserves, and cash on hand resulting from working capital borrowings made after the end of the quarter. The general partner establishes cash reserves to provide for the proper conduct of our business, including (i) to fund future capital expenditures, (ii) to comply with applicable laws, debt instruments, or other agreements, or (iii) to provide funds for unitholder distributions for any one or more of the next four quarters. The Board declared a cash distribution to unitholders for the third quarter of 2024 of $0.875 per unit, or $340.9 million in the aggregate. The cash distribution is payable on November 14, 2024, to our unitholders of record at the close of business on November 1, 2024.
To facilitate the distribution of available cash, during 2022 we adopted a financial policy that provided for an additional distribution (“Enhanced Distribution”) to be paid in conjunction with the regular first-quarter distribution of the following year (beginning in 2023), in a target amount equal to Free cash flow generated in the prior year after subtracting Free cash flow used for the prior year’s debt repayments, regular-quarter distributions, and unit repurchases. This Enhanced Distribution is subject to Board discretion, the establishment of cash reserves for the proper conduct of our business, and is also contingent on the attainment of prior year-end net leverage thresholds (the ratio of our total principal debt outstanding less total cash on hand as of the end of such period, as compared to our trailing-twelve-months Adjusted EBITDA) after taking the Enhanced Distribution for such prior year into effect. Free cash flow and Adjusted EBITDA are defined under the caption Reconciliation of Non-GAAP Financial Measures within this Item 2.
In 2022, we announced a common-unit buyback program of up to $1.25 billion through December 31, 2024. The common units may be purchased from time to time in the open market at prevailing market prices or in privately negotiated transactions. The timing and amount of purchases under the program will be determined based on ongoing assessments of capital needs, our financial performance, the market price of our common units, and other factors, including organic growth and acquisition opportunities and general market conditions. The program does not obligate us to purchase any specific dollar amount or number of units and may be suspended or discontinued at any time. During the nine months ended September 30, 2024, there were no common units repurchased. As of September 30, 2024, we had an authorized amount of $627.8 million remaining under the program.
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 September 30, 2024, we had a $186.5 million working capital surplus, which we define as the amount by which current assets exceed current liabilities. As of September 30, 2024, 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 9—Selected Components of Working Capital and Note 10—Debt and Interest Expense in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q.

Capital expenditures. Our business is capital intensive, requiring significant investment to maintain and improve existing facilities or to develop new midstream infrastructure. Capital expenditures include maintenance capital expenditures, which include those expenditures required to maintain existing operating capacity and service capability of our assets, and expansion capital expenditures, which include expenditures to construct new midstream infrastructure and expenditures incurred to reduce costs, increase revenues, or increase system throughput or capacity from current levels.
Capital expenditures in the consolidated statements of cash flows reflect capital expenditures on a cash basis, when payments are made. Capital incurred is presented on an accrual basis. Acquisitions and capital expenditures as presented in the consolidated statements of cash flows and capital incurred were as follows:

Capital expenditures increased by $58.7 million for the nine months ended September 30, 2024, primarily due to increases of (i) $71.0 million at the West Texas complex, primarily attributable to engineering, equipment, and construction milestone payments for the North Loving Plant, (ii) $25.3 million at the Powder River Basin complex primarily attributable to the acquisition of Meritage, (iii) $8.9 million in corporate-level capital expenditures primarily related to information technology initiatives, (iv) $8.2 million at the DJ Basin complex due to the purchase of a field office in the first quarter of 2024 and an increase in well connection and pipeline projects, and (v) $7.5 million at the Chipeta complex primarily related to expansion projects. These increases were offset partially by decreases of (i) $41.8 million at the DBM oil system related to a decrease in pipeline, oil treating, and oil pumping projects and (ii) $18.5 million at the DBM water systems due to reduced construction of certain water-disposal wells, facilities, and well-connect projects.

Operating activities. Net cash provided by operating activities increased for the nine months ended September 30, 2024, primarily due to higher cash operating income, partially offset by lower distributions from equity investments and higher interest expense. Refer to Operating Results within this Item 2 for a discussion of our results of operations as compared to the prior periods.

Net cash used in financing activities for the nine months ended September 30, 2023, primarily included the following:
$845.0 million of repayments of outstanding borrowings under the RCF;

$778.3 million of distributions paid to WES unitholders and noncontrolling interest owners;

$259.8 million to purchase and retire portions of certain of WES Operating’s senior notes via open-market repurchases;

$213.1 million to redeem the total principal amount outstanding on the Floating-Rate Senior Notes due 2023 at par value;

$134.6 million of unit repurchases;

$740.6 million of net proceeds from the 6.150% Senior Notes due 2033 issued in April 2023, which were used to repay borrowings under the RCF and for general partnership purposes;

$595.1 million of net proceeds from the 6.350% Senior Notes due 2029 issued in September 2023, which were used to fund a portion of the aggregate purchase price for the Meritage acquisition, to pay related costs and expenses, and for general partnership purposes; and

$470.0 million of borrowings under the RCF, which were used for general partnership purposes.

Debt and credit facilities. As of September 30, 2024, the carrying value of outstanding debt was $7.9 billion, and 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 nine months ended September 30, 2024, WES Operating (i) completed the public offering of $800.0 million in aggregate principal amount of 5.450% Senior Notes due 2034, (ii) purchased and retired $150.0 million of certain of its senior notes via open-market repurchases with cash from operations, and (iii) entered into an amendment to the RCF to exercise an option to extend the maturity date of the RCF from April 2028 to April 2029, for each extending lender. As of September 30, 2024, the 3.100% Senior Notes due 2025 and 3.950% Senior Notes due 2025 were classified as short-term debt on the consolidated balance sheet.
For additional information on our senior notes, RCF, and commercial paper program, see Note 10—Debt and Interest Expense in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q.

Credit risk. We bear credit risk through exposure to non-payment or non-performance by our counterparties, including Occidental, financial institutions, customers, and other parties. Generally, non-payment or non-performance results from a customer’s inability to satisfy payables to us for services rendered, minimum-volume-commitment deficiency payments owed, or volumes owed pursuant to gas- or NGLs-imbalance agreements. We examine and monitor the creditworthiness of customers and may establish credit limits for customers. We are subject to the risk of non-payment or late payment by producers for gathering, processing, transportation, and disposal fees. Additionally, we continue to evaluate counterparty credit risk and, in certain circumstances, are exercising our 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.

Table of Contents
Noncontrolling interest. WES Operating’s noncontrolling interest consists of the 25% third-party interest in Chipeta. See Note 1—Description of Business and Basis of Presentation in the Notes to Consolidated Financial Statements under Part I, Item 1 of this Form 10-Q.

WES Operating distributions. WES Operating distributes all of its available cash on a quarterly basis to WES Operating unitholders in proportion to their share of limited partner interests in WES Operating. See Note 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, 2023.

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.

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, 2023, except as noted below and in Outlook under Part I, Item 2 of this Form 10-Q.
For the nine months ended September 30, 2024, 95% of our wellhead natural-gas volume (excluding equity investments) and 100% of our crude-oil and produced-water throughput (excluding equity investments) were serviced under fee-based contracts. A 10% increase or decrease in commodity prices would not have a material impact on our operating income (loss), financial condition, or cash flows for the next 12 months, excluding the effect of imbalances.

Interest-rate risk. The Federal Open Market Committee increased its target range four times for the federal funds rate in 2023 and decreased its target range once during the nine months ended September 30, 2024. Any future increases in the federal funds rate likely will result in an increase in financing costs. As of September 30, 2024, 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 September 30, 2024, 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 4, “Management”) performed an evaluation of WES’s and WES Operating’s disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. WES’s and WES Operating’s disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports that are filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the SEC, and to ensure that the information required to be disclosed in the reports that are filed or submitted under the Exchange Act is accumulated and communicated to management, including the principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Based on this evaluation, Management concluded that WES’s and WES Operating’s disclosure controls and procedures were effective as of September 30, 2024.

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 September 30, 2024, 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 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.
    
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, 2023, 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 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 September 30, 2024, 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).
