Duke Energy plans $1.75B equity units offering to refinance debt

Duke Energy announced a $1.75 billion equity units offering on August 10, 2026, as the utility seeks to refinance debt and strengthen its balance sheet amid rising capital demands. The Charlotte, North Carolina-based company plans to sell 35 million equity units at $50 each in a public offering, with an option for underwriters to purchase an additional 5 million units.

Each equity unit will consist of a contract to purchase Duke Energy common stock in the future and two 1/40 undivided beneficial ownership interests in the company’s remarketable senior notes with a principal amount of $1,000. The units are expected to begin trading on the New York Stock Exchange within 30 days of issuance.

Duke Energy intends to use the net proceeds to redeem $500 million of its outstanding 3.25% Junior Subordinated Debentures due 2082, repay a portion of its commercial paper, and for general corporate purposes. This refinancing move comes as utilities face mounting pressure to fund infrastructure modernization and meet surging electricity demand from data centers and grid electrification.

The offering comes roughly five months after Duke Energy sold $1 billion in convertible senior notes due 2029 to refinance higher-coupon convertible debt maturing in April 2026. The company’s debt-to-equity ratio stood at 1.45 as of the second quarter of 2026, about 16.1% above its 10-year average of 1.25, according to financial data.

Duke Energy’s stock fell 1.7% on the announcement, reflecting typical market reaction to equity dilution from new offerings. The utility serves 8.7 million electric customers across North Carolina, South Carolina, Florida, Indiana, Ohio, and Kentucky, and operates 55,700 megawatts of energy capacity. Its natural gas utilities serve 1.6 million customers in four states.

Barclays, Bank of America Securities, Mizuho, Citigroup, Goldman Sachs, JPMorgan Chase, Morgan Stanley, Truist Securities, and Wells Fargo Securities are serving as book-running managers for the offering. The company expects the offering to close on August 13, 2026.
