What Happened
The Williams Companies, Inc. (WMB) announced on January 5, 2026 that it priced an underwritten public offering of $2.75 billion aggregate principal amount of senior notes and entered into an underwriting agreement with Barclays, BofA Securities, CIBC World Markets and Truist as representatives. The offering consists of $500 million of 5.650% Senior Notes due 2033 (an additional issuance that will trade interchangeably with the $750 million of 2033 notes issued March 2, 2023), $1.25 billion of 5.150% Senior Notes due 2036, and $1.0 billion of 5.950% Senior Notes due 2056. The offering is registered on Form S-3 (Reg. No. 333-277232) and was expected to close on January 8, 2026; related documents and a press release were furnished with the 8-K.

Key Details

• Total offering size: $2.75 billion (2033: $500M; 2036: $1.25B; 2056: $1.0B).
• Coupon rates and maturities: 5.650% due 2033; 5.150% due 2036; 5.950% due 2056.
• New 2033 notes are an additional issuance fungible with the $750M 2033 series issued March 2, 2023.
• Underwriting agreement dated January 5, 2026; prospectus supplement filed January 6, 2026; legal opinion from Gibson, Dunn & Crutcher LLP filed as an exhibit.

Why It Matters
This transaction raises $2.75 billion of long-term, fixed-rate debt, extending Williams’ maturity profile out to 2056 and locking in known interest costs for these tranches. For investors, the offering affects the company’s capital structure and interest expense profile; the filing does not specify the use of proceeds. The additional 2033 issuance is fungible with existing notes, which can increase the trading float of that series.
