Western Midstream (WES) Q4 2025 earnings review
Capex Surprise Unlocks Value; Water Segment Explodes
Western Midstream delivered a solid Q4/FY25 beat, but the real story is the surprising pivot in capital discipline for 2026. While the market braced for >$1.1B in 2026 spending, management guided to a midpoint of $925M—slashing expectations by ~16% while still guiding for 5% EBITDA growth. Operationally, the Aris acquisition transformed the profile immediately, driving a 121% sequential jump in water volumes. While low commodity prices are softening activity in the DJ and Powder River basins, the Delaware Basin machine and strict cost controls (O&M down 12% ex-Aris) are more than offsetting the drag.
🐂 Bull Case
Management guided 2026 Capex to $850M-$1.0B (midpoint $925M), significantly below the previously communicated floor of '$1.1 billion.' This capital efficiency directly boosts Free Cash Flow availability for distributions and buybacks.
The Aris acquisition is fully integrated and performing. Water throughput skyrocketed 121% QoQ to 2.69M Bbls/d. Water is no longer a byproduct; it is now a primary growth engine alongside Delaware gas.
🐻 Bear Case
Low commodity prices are biting in secondary basins. Management explicitly guided for portfolio-wide Crude/NGLs throughput to decline and Natural Gas to remain flat in 2026 due to anticipated declines in 'other operating basins' (DJ/PRB).
While EBITDA is record-breaking, Q4 Net Income attributable to LP fell to $187M (vs $326M in Q3) driven by higher depreciation from the expanded asset base and a $29.5M non-cash revenue adjustment.
⚖️ Verdict: 🟢
Bullish. The operational beat is good, but the capital discipline surprise is excellent. By lowering 2026 Capex expectations while maintaining EBITDA growth targets, WES has materially improved its Free Cash Flow yield outlook.
Key Themes
The Capex Surprise
In prior quarters, management signaled 2026 Capex would be 'at least $1.1 billion' to fund Pathfinder and North Loving II. The official 2026 guidance range is $850M–$1.0B. Management attributed this to 'adjusting spending to reflect the softer macroeconomic backdrop.' This flexibility preserves cash flow without sacrificing the 5% EBITDA growth target.
Water Volume Step-Change
The Aris acquisition closed in Q4, fundamentally altering WES's operational mix. Q4 Produced Water throughput hit 2.69 million Bbls/d, a massive 121% increase sequentially. WES is now a dominant water midstream player in the Delaware, providing a fee-based hedge against volatile commodity pricing.
Tale of Two Basins
The portfolio is bifurcating. The Delaware Basin remains strong (Gas +9% YoY, Water +40% YoY), but legacy assets are dragging. Management expects 'anticipated declines' in other basins to result in flat overall gas volumes and declining crude volumes for 2026. WES is becoming increasingly reliant on the Delaware Basin for growth.
Operational Efficiency
Despite adding Aris, WES is aggressively cutting legacy costs. Excluding Aris, O&M expense dropped 12% YoY in Q4. For 2026, legacy O&M is expected to decline further, and total partnership O&M is guided up only 10-15% despite the massive addition of Aris assets. This indicates successful synergy capture and operational discipline.
Revenue Adjustments
Q4 results included a $29.5 million non-cash decrease to revenue related to cumulative adjustments for cost-of-service agreements in the DJ and Springfield systems. While non-cash, these adjustments obscured the revenue line and highlight the complexity/volatility of contract rate redeterminations.
Other KPIs
Accelerating. Beat the high end of guidance ($1.475B) and grew 15% YoY. This surplus cash generation allowed WES to return $1.43B to unitholders while keeping leverage near 3.0x.
Stable. Calculated as Adj. EBITDA ($635.6M) divided by Total Revenue ($1.031B). Despite the revenue adjustment headwinds and integration costs, margins remain robust.
Stable. Management maintained leverage near 3.0x throughout the year despite the Aris acquisition and capital returns, adhering strictly to their financial framework.
Guidance
Accelerating. The midpoint ($2.6B) implies ~5% growth over record 2025 results ($2.48B). Growth is driven by Aris full-year contribution and Delaware expansion, offsetting declines in legacy basins.
Decelerating. This is a crucial pivot. Previous messaging suggested >$1.1B. The reduction to a ~$925M midpoint reflects responsiveness to the macro environment and improves the FCF outlook significantly.
Stable. At the midpoint ($1.95B), this covers the distribution comfortably. Management plans a distribution increase to $0.93/unit starting Q1 2026 (+2.2% vs prior).
Key Questions
Capex Reduction Specifics
The drop in 2026 Capex guidance from '$1.1B+' to ~$925M is significant. Which specific projects were deferred or cancelled to achieve this, and does this impact 2027 growth capacity?
DJ Basin Decline Rate
With 2026 crude/NGL throughput expected to decline portfolio-wide due to 'other operating basins,' what is the specific decline rate assumed for the DJ Basin, and do you see any scenario where activity rebounds in 2H 2026?
Aris Synergy Timeline
You noted 85% of the $40M target synergies will be captured by end of Q1 2026. Are there additional revenue synergies (e.g., skim oil recovery, water recycling sales) included in the 2026 EBITDA guidance, or is that potential upside?
