Subsequent Events [Abstract] |
Subsequent Events [Text Block] | Note 11 – Subsequent Events Momentum Midstream Acquisition In July 2026, Williams agreed to acquire M6 Midstream LLC (Momentum) for total consideration up to $5.5 billion, including approximately $2 billion of Williams common stock, subject to certain holding restrictions. Momentum’s assets in the Haynesville Shale region include 6 Bcf/d of gathering capacity and 4 Bcf/d of pipeline capacity. The transaction is expected to close later this year, subject to customary closing conditions and regulatory approvals. Power Innovation Joint Venture In July 2026, Williams sold a 49 percent noncontrolling interest in five power innovation projects, Socrates, Apollo, Aquila, Socrates the Younger, and Neo, to an investor in exchange for $5.34 billion of committed capital. The initial July 2026 contribution of approximately $3.75 billion is expected to increase both Capital in excess of par value and Noncontrolling interests in consolidated subsidiaries, reflecting the change in Williams’ ownership interest while retaining control as an equity transaction. The balance of the committed capital is expected to be received through early 2027. Cash distributions will generally align with ownership percentages and distributions to the investor in excess of a target return will serve to reduce its investment balance. In addition, Williams has a buyout right between years 7 and 14 based on the investor’s outstanding investment balance, preserving Williams’ long-term upside in the projects.
