WILLIAMS COMPANIES, INC. (WMB) is issuing a total of $2.75 billion of senior unsecured notes under its shelf registration, split into $500 million 5.000% notes due 2029, $1.0 billion 5.600% notes due 2033, $750 million 5.800% notes due 2036 and $500 million 6.400% notes due 2056. The notes pay semiannual interest beginning in 2027 and may be redeemed at a make-whole premium before their respective Par Call Dates, and at par plus accrued interest thereafter.
The notes rank as senior unsecured obligations, equal with Williams’ existing senior unsecured debt, effectively subordinated to any future secured debt and structurally subordinated to approximately $7.0 billion of subsidiary indebtedness outstanding as of June 30, 2026. As of that date, total indebtedness was about $30.8 billion, rising to about $33.0 billion on an as-adjusted basis assuming this offering.
Williams expects net proceeds of about $2.72 billion, to be used to repay outstanding commercial paper (about $910 million as of September 4, 2026) and for general corporate purposes, including capital expenditures. The notes are a new issue with no existing trading market, and Williams does not plan to list them on an exchange.
The Williams Companies, Inc. (WMB) is offering multiple series of senior unsecured notes under its February 2024 shelf registration, with semi-annual cash interest payments beginning in 2027 and optional redemption features including a make-whole call before specified par call dates and par redemption thereafter.
The notes will rank equally with Williams’ other senior unsecured debt, be effectively subordinated to any secured debt and structurally subordinated to obligations of subsidiaries, and will not be guaranteed. There is no planned exchange listing and no mandatory redemption or sinking fund, so trading liquidity may be limited.
Net proceeds are expected to be used to repay commercial paper and for general corporate purposes, including capital expenditures. As of June 30, 2026, Williams had $30.8 billion of indebtedness (including $7.0 billion at subsidiaries), total capitalization of $46.2 billion, and commercial paper outstanding of $475 million (rising to $910 million by September 4, 2026 at a 3.8802% weighted average rate). Recent transactions include a $5.5 billion Momentum Midstream acquisition and a power innovation joint venture involving $5.34 billion of committed capital.
The Williams Companies, Inc. (WMB) has filed a prospectus supplement registering the potential resale by existing stockholders of up to 26,874,496 shares of common stock that were issued as part of its acquisition of M6 Midstream LLC. These shares are being sold by the stockholders, not by Williams, and Williams will not receive any proceeds from their sale, though it will bear registration-related costs.
Certain holders owning 25,557,199 shares are subject to Lock-Up Restrictions that cap aggregate sales at 537,496 shares per day until March 3, 2027; as of the prospectus date, 1,854,793 shares are immediately saleable, with the balance becoming available on a rolling basis. As context, Williams had 1,233,167,472 shares outstanding as of July 30, 2026, which is a baseline ownership figure rather than the amount registered for resale.
The Williams Companies, Inc. is planning an underwritten public offering of senior unsecured notes, including additional 5.650% notes due 2033 and two new series of senior notes with later maturities. The new 2033 notes will form a single series with an existing 5.650% 2033 issue and pay interest semi-annually. The notes will rank equally with Williams’ other senior unsecured debt and be structurally subordinated to obligations of its subsidiaries.
Williams expects to use the net proceeds primarily to repay near-term debt, including its $1.1 billion 5.400% Senior Notes due 2026, and for general corporate purposes. The company highlights that, as of September 30, 2025, pro forma for recent Transco and Northwest Pipeline financings, it had approximately $28.8 billion of total indebtedness and notes that its debt agreements contain covenants that may affect financial and operating flexibility.
