Williams has priced a $2.75 billion public offering of senior notes, providing the energy infrastructure company with additional long-term capital that it plans to use primarily to repay outstanding commercial paper and support general corporate purposes, including capital expenditures.
The financing is divided across four separate tranches with maturities ranging from 2029 through 2056, giving Williams a mix of shorter-, intermediate- and longer-duration debt within a single transaction.
The first tranche consists of $500 million of 5.000% Senior Notes due 2029, priced at 99.931% of par.
Williams also priced $1 billion of 5.600% Senior Notes due 2033 at 99.999% of par, making it the largest individual component of the offering.
A third tranche includes $750 million of 5.800% Senior Notes due 2036, priced at 99.819% of par.
The longest-dated portion of the transaction consists of $500 million of 6.400% Senior Notes due 2056, priced at 99.800% of par.
Together, the four issuances total $2.75 billion in principal amount and extend across nearly three decades of maturities.
The offering is expected to settle on September 10, 2026, subject to customary closing conditions.
Williams said it intends to use the net proceeds from the transaction to repay outstanding commercial paper and for other general corporate purposes.
Those purposes may include funding capital expenditures, giving the company additional flexibility to finance investment across its energy infrastructure portfolio while replacing shorter-term borrowing with longer-duration debt.
The transaction therefore serves both a refinancing and corporate funding function, allowing Williams to address existing commercial paper obligations while maintaining capacity for ongoing investment.
The multi-tranche structure also gives the company debt maturities spread across 2029, 2033, 2036 and 2056, rather than concentrating the entire financing in a single maturity period.
Citigroup Global Markets, Mizuho Securities USA, Morgan Stanley and SMBC Nikko Securities America are serving as joint book-running managers for the offering.
The offering is being conducted under an automatic shelf registration statement that Williams previously filed with the U.S. Securities and Exchange Commission and that became effective upon filing.
Williams is one of the largest natural gas infrastructure operators in the U.S., with a network that the company says delivers approximately one-third of the nation’s natural gas.
Its infrastructure supplies natural gas used for residential heating, cooking and electricity generation, positioning the company across a significant portion of the country’s energy transportation system.
The new debt financing comes as Williams continues investing in infrastructure to support growing natural gas demand and broader energy needs.
By combining shorter-term maturities with a substantial 30-year tranche due in 2056, the transaction provides Williams with a broad maturity profile while raising a significant amount of capital in a single public debt offering.
