Duke Energy Prices Upsized $1.3 Billion Convertible Notes Offering

Duke Energy (NYSE: DUK) expanded its offering of convertible senior notes to $1.3 billion, up from the $1 billion originally anticipated. The company also provided initial purchasers with a 13-day option to buy up to an additional $200 million in notes. The transaction is scheduled to close on March 12, 2026, pending standard closing conditions.

The company estimates net proceeds will reach approximately $1.29 billion, or $1.48 billion if the overallotment option is fully exercised. These funds are earmarked to repay $1.725 billion of 4.125% convertible senior notes that reach maturity on April 15, 2026. Remaining funds will be used for general corporate purposes.

The new unsecured notes will mature on March 15, 2029, and pay interest semi-annually every March and September, beginning in late 2026. The initial conversion rate is set at 6.2277 shares per $1,000 of principal, which translates to a conversion price of roughly $160.57 per share. This represents a 22.50% premium over the $131.08 closing price on the New York Stock Exchange on March 9, 2026.

Upon conversion, Duke Energy will satisfy the principal amount in cash. Any value exceeding the principal may be settled in cash, common stock, or a combination of both at the company's discretion. The notes are not redeemable by the issuer prior to their maturity date.
