FOURTH-QUARTER AND FULL-YEAR 2023 HIGHLIGHTS

Achieved record annual natural-gas throughput of 4.4 Bcf/d, representing a 5-percent year-over-year increase⁽²⁾, in-line with our revised 2023 expectations of mid-single-digits growth.
Gathered record annual crude-oil and NGLs throughput of 652 MBbls/d, representing a 7-percent year-over-year increase⁽³⁾, exceeding our 2023 expectations of low-single-digits growth.
Gathered record annual produced-water throughput of 1,009 MBbls/d, representing a 21-percent year-over-year increase, exceeding our revised 2023 expectations of upper-teens growth.
Achieved year-over-year throughput growth across all products in the Delaware Basin of 11-percent, 8-percent, and 21-percent, for natural gas, crude oil and NGLs, and produced water, respectively.
Sanctioned the 250 MMcf/d North Loving processing plant in May 2023, and materially progressed construction of the 300 MMcf/d Mentone III processing train, both of which are underpinned by commercial agreements containing either acreage dedications or significant minimum-volume commitments.
Announced and closed the acquisition of Meritage Midstream Services II, LLC ("Meritage"), expanding WES's position to the largest gathering and processing footprint in the Powder River Basin.
Executed on our capital return framework by returning $978.4 million in distributions, inclusive of two Base Distribution increases and the payment of our first Enhanced Distribution, and $134.6 million in unit repurchases, which represents approximately 15-percent of WES's unaffected common unit count since becoming a standalone entity in early 2020.
Obtained full investment-grade ratings in May 2023 and raised $1.350 billion through two bond offerings to partially fund the Meritage acquisition, refinance existing borrowings, and enhance the partnership's overall liquidity.

On February 13, 2024, WES paid its fourth-quarter 2023 per-unit Base Distribution of $0.575, consistent with the Partnership's third-quarter Base Distribution. Fourth-quarter and full-year 2023 Free cash flow⁽¹⁾ after distributions totaled $58.6 million and negative $14.2 million, respectively. Fourth-quarter and full-year 2023 capital expenditures⁽⁴⁾totaled $180.7 million and $739.1 million, respectively.

Fourth-quarter 2023 natural-gas throughput⁽⁵⁾ averaged 4.9 Bcf/d, representing a 9-percent sequential-quarter increase⁽²⁾. Fourth-quarter 2023 throughput for crude-oil and NGLs assets⁽⁵⁾ averaged 702 MBbls/d, representing a 5-percent sequential-quarter increase⁽³⁾. Fourth-quarter 2023 throughput for produced-water assets⁽⁵⁾ averaged 1,054 MBbls/d, representing a 2-percent sequential-quarter decrease.

Full-year 2023 natural-gas throughput⁽⁵⁾ averaged 4.4 Bcf/d, representing a 5-percent year-over-year increase⁽²⁾. Full-year 2023 throughput for crude-oil and NGLs assets⁽⁵⁾ averaged 652 MBbls/d, representing a 7-percent year-over-year increase⁽³⁾. Full-year 2023 throughput for produced-water assets⁽⁵⁾ averaged 1,009 MBbls/d, representing a 21-percent year-over-year increase.

"2023 was a successful, pivotal year for WES as we achieved operated throughput growth of approximately 7-percent, 5-percent, and 21-percent for natural gas, crude-oil and NGLs, and produced water, respectively. We also continued to diversify our asset and customer base through accretive M&A in the Powder River Basin, all while returning $1.113 billion to unitholders through our capital-return framework. Our ability to successfully capture significant Delaware Basin throughput growth, efficiently expand our asset footprint, and maintain cost and capital discipline, positions WES to enter 2024 on solid financial footing with significant operational tailwinds," said Michael Ure, President and Chief Executive Officer.

"Focusing on the Delaware Basin, this was an extremely successful year for WES as throughput increased across all three products resulting in record annual throughput from the basin for our partnership. We also extended the duration of our agreements and our firm-processing commitments with Occidental through 2035 and continued to diversify our customer base in the basin by adding 12 new third-party customers across our natural-gas and produced-water businesses. These accomplishments have resulted in meaningful growth and have helped WES grow its natural-gas volumes at a rate more than double the rate of throughput growth in the basin since early 2021. Our commercial successes were the primary drivers behind the sanctioning of both Mentone III and the North Loving plant, which together will increase our total operated processing capacity in the basin by 34-percent compared to year-end 2023 and maintain WES's position as one of the top natural-gas processors in the Delaware Basin. In addition to advancing our strong Delaware Basin position, we remained focused on growing the entirety of our business. Our expansion in the Powder River Basin and volume growth expectations in the DJ Basin place our partnership in a position of strength as we enter 2024," Mr. Ure continued.

"Additionally, concurrent with this release, we are announcing that we have entered into a series of agreements to sell WES's equity interests in multiple non-core assets for aggregate proceeds of $790.0 million and for an aggregate multiple of approximately 9.6 times 2023 Adjusted EBITDA. These divestitures are in line with our strategy of divesting non-core, non-operated assets and redeploying that capital into our operated asset base with the goal of driving operational efficiencies alongside throughput growth and creating incremental value for our unitholders," concluded Mr. Ure.

RECONCILIATION OF GAAP TO NON-GAAP MEASURES

WES defines 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.

WES 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) interest income, (v) income tax benefit, (vi) other income, and (vii) the noncontrolling interest owners' proportionate share of revenues and expenses.

WES defines Free cash flow as net cash provided by operating activities less total capital expenditures and contributions to equity investments, plus distributions from equity investments in excess of cumulative earnings. Management considers Free cash flow an appropriate metric for assessing capital discipline, cost efficiency, and balance-sheet strength. Although Free cash flow is the metric used to assess WES's ability to make distributions to unitholders, this measure should not be viewed as indicative of the actual amount of cash that is available for distributions or planned for distributions for a given period. Instead, Free cash flow should be considered indicative of the amount of cash that is available for distributions, debt repayments, and other general partnership purposes.

Below are reconciliations of (i) gross margin (GAAP) to Adjusted gross margin (non-GAAP), (ii) net income (loss) (GAAP) and net cash provided by operating activities (GAAP) to Adjusted EBITDA (non-GAAP), and (iii) net cash provided by operating activities (GAAP) to Free cash flow (non-GAAP), as required under Regulation G of the Securities Exchange Act of 1934. Management believes that Adjusted gross margin, Adjusted EBITDA, and Free cash flow are widely accepted financial indicators of WES's financial performance compared to other publicly traded partnerships and are useful in assessing WES's ability to incur and service debt, fund capital expenditures, and make distributions. Adjusted gross margin, Adjusted EBITDA, and Free cash flow as defined by WES, may not be comparable to similarly titled measures used by other companies. Therefore, WES's Adjusted gross margin, Adjusted EBITDA, and Free cash flow should be considered in conjunction with net income (loss) attributable to Western Midstream Partners, LP and other applicable performance measures, such as gross margin or cash flows provided by operating activities.
