Material Changes vs. Prior Period
- Acquisitions: The primary driver of growth was the full-year inclusion of earnings from the EnLink Acquisition (completed Jan 31, 2025) and the Medallion Acquisition (completed Oct 31, 2024). Additional 2025 acquisitions included the Delaware Basin JV (May 2025) and an additional interest in BridgeTex (July 2025).
- Segment Performance:
- Natural Gas Gathering and Processing: Adjusted EBITDA increased $654 million, driven by EnLink earnings and higher volumes in Mid-Continent and Rocky Mountain regions.
- Natural Gas Liquids: Adjusted EBITDA increased $236 million due to EnLink earnings and higher exchange services.
- Natural Gas Pipelines: Adjusted EBITDA decreased $39 million, primarily due to the 2024 divestiture of interstate pipelines, partially offset by EnLink earnings.
- Refined Products and Crude: Adjusted EBITDA increased $285 million, driven by Medallion and EnLink earnings and lower operating costs.
- Divestitures: In December 2024, the company sold three interstate natural gas pipeline systems for $1.2 billion, recognizing a $227 million gain.
- Interest Expense: Net interest expense increased to $1,783 million (from $1,371 million) due to higher debt balances from acquisitions and new debt issuances.
Guidance, Outlook, and Risks
- Capital Allocation: The Board increased the quarterly dividend to $1.07 per share (4% increase). The company has a $2.0 billion share repurchase program, under which $234 million was repurchased by year-end 2025.
- 2026 Capital Expenditures: Management expects total capital expenditures of $2.7 billion to $3.2 billion in 2026.
- Key Projects: Major ongoing projects include the Bighorn processing plant (Permian Basin), Texas City Logistics export terminal, and the Eiger Express Pipeline. Most growth projects are fee-based and not contingent on commodity price improvements.
- Risks:
- Regulatory: Changes in EPA regulations regarding methane emissions and the "One Big Beautiful Bill Act" (OBBBA) which suspended certain methane fees but created uncertainty regarding future enforcement.
- Market: Volumetric risk in Gathering/Processing and NGL segments due to drilling activity and commodity prices.
- Operational: Cybersecurity threats and physical hazards associated with pipeline operations.
Investor Verification Checklist
- Acquisition Integration: Verify the realization of synergies and cost savings from the EnLink and Medallion acquisitions as projected in management commentary.
- Debt Servicing: Monitor the impact of the $34 billion debt load on cash flows, specifically the ability to fund the $2.7–$3.2 billion 2026 capital program while maintaining dividend growth.
- Regulatory Landscape: Track the status of the EPA's "Waste Emissions Charge" (Methane Fee) and the potential for litigation regarding the elimination of the 2009 GHG endangerment finding.
- Capital Project Execution: Confirm timelines and cost estimates for major projects like the Texas City Logistics terminal and Eiger Express Pipeline, noting potential inflationary pressures on construction costs.
- Commodity Hedging: Review the effectiveness of hedging strategies in the Natural Gas Gathering and Processing segment, which retains exposure to commodity price risk via "fee with POP" contracts.
