Material Changes vs. Prior Period
- Revenue Growth: Consolidated revenues increased 13% year-over-year (YoY) to $8.752 billion for the nine months ended September 30, 2025, compared to $7.760 billion in 2024. This was driven by higher service revenues from expansion projects and acquisitions.
- Net Income: Net income attributable to Williams increased 8% YoY to $1.884 billion. The increase was supported by higher operating income, partially offset by higher interest expense and income tax provisions.
- Commodity Derivatives: Net gain from commodity derivatives improved significantly to $30 million in 2025 from a loss of $133 million in 2024, largely due to favorable changes in unrealized gains.
- Segment Performance:
- Transmission, Power & Gulf: Modified EBITDA increased to $2.722 billion (9M 2025) from $2.448 billion (9M 2024), driven by Transco rate increases and new capacity from expansion projects.
- West: Modified EBITDA rose to $1.037 billion, aided by the Louisiana Energy Gateway and Rimrock Asset Purchase, though partially offset by a $25 million asset write-off in the DJ Basin.
- Gas & NGL Marketing: Modified EBITDA improved to $176 million from a loss of $14 million, primarily due to favorable unrealized derivative gains.
Guidance, Outlook, and Risks
- Capital Expenditure Guidance: Williams expects 2025 growth capital and investment expenditures to range from $3.95 billion to $4.25 billion, excluding acquisitions. This includes Power Innovation projects, Haynesville Shale growth, and Transco expansions.
