• Gathered record Delaware Basin crude-oil and NGLs throughput of 269 MBbls/d for the second quarter, representing a 5-percent sequential-quarter increase.
• Gathered record Delaware Basin produced-water throughput of 1,242 MBbls/d for the second quarter, representing a 4-percent sequential-quarter increase.
• Retired $337 million of senior notes in June of 2025 with cash on hand.
• Subsequent to quarter end, sanctioned a new 300 MMcf/d cryogenic processing train in the North Loving area of our West Texas complex ("North Loving Train II") with an expected in-service date early in the second quarter of 2027.
• Subsequent to quarter end, and as announced earlier today, executed an agreement to acquire Aris Water Solutions, Inc. ("Aris") (NYSE: ARIS) in a transaction with an enterprise value of approximately $2.0 billion, which is expected to close during the fourth quarter of 2025.

On August 14, 2025, WES will pay its second-quarter 2025 per-unit distribution of $0.910, or $3.64 on an annualized basis, which is in line with the prior quarter's distribution. Second-quarter 2025 Free Cash Flow⁽¹⁾ after distributions totaled $33.1 million.

Second-quarter 2025 natural-gas throughput⁽⁴⁾ averaged 5.3 Bcf/d, representing a 3-percent sequential-quarter increase. Second-quarter 2025 crude-oil and NGLs throughput⁽⁴⁾ averaged 532 MBbls/d, representing a 6-percent sequential-quarter increase. Second-quarter 2025 produced-water throughput⁽⁴⁾ averaged 1,217 MBbls/d, representing a 4-percent sequential-quarter increase.

"WES had a successful second quarter as we generated the highest quarterly Adjusted EBITDA in our partnership's history, delivered increased throughput across all core operating basins and across all products, and executed on numerous significant growth initiatives," commented Oscar Brown, President and Chief Executive Officer. "Additionally, our strategic focus on productivity and efficiency has resulted in cost reductions and process improvements, which should help WES remain competitive and better execute on our near-term growth plans. These results have kept WES on track to achieve our annual throughput growth expectations, and we remain within our previously announced financial guidance ranges for the year."

"After evaluating multi-year throughput forecasts and conducting numerous discussions with our customers in West Texas, we are confident in sustained producer activity and remain committed to meeting our customers' infrastructure needs. As such, we have sanctioned North Loving Train II, a 300 MMcf/d cryogenic natural-gas processing train, that will increase our West Texas complex processing capacity to approximately 2.5 Bcf/d. This expansion further solidifies WES's position as one of the top natural-gas processors in the Delaware Basin and will better position us to continue supporting the development of our customer's high-quality acreage positions in the basin."

"Today, we also announced WES's acquisition of Aris in a transaction with an enterprise value of approximately $2.0 billion, which reinforces WES as a leading midstream water services provider in the Delaware Basin. This strategic transaction, which is expected to be accretive to 2026 Free Cash Flow per unit and targets approximately $40 million of annualized cost synergies, establishes a differentiated, produced-water system across West Texas and southern New Mexico that is supported by highly-economic, long-term dedications from investment-grade customers. Additionally, we firmly believe this transaction will enhance our ability to compete for new business across our natural-gas, crude-oil, and produced-water businesses, adding meaningful scale, marking our entrance further into New Mexico, and making WES the largest three-stream midstream service provider in the Delaware Basin. Also, by prudently financing this transaction with a combination of equity and cash, we expect pro forma net leverage to remain at approximately 3.0x."

"Finally, we will remain focused on diligently executing our growth strategy, as the Aris acquisition, North Loving Train II, and other organic expansion projects, such as the Pathfinder pipeline, greatly support our growth outlook in 2026, 2027, and beyond. Our long-term contract portfolio, strong balance sheet, and investment-grade credit ratings all provide the financial flexibility needed to support our expansion plans over the coming years and generate value for our unitholders," concluded Mr. Brown.

GUIDANCE

Given the expected timing of closing within the fourth quarter, WES is not updating its 2025 financial guidance ranges and expects to incorporate the impact of the Aris acquisition into its 2026 guidance projections that will be announced in late February of 2026 in conjunction with WES's fourth-quarter 2025 earnings report.

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 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.

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.

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.
