Duke Energy Corporation announced on Mar. 10 the pricing of its offering of $1.3 billion aggregate principal amount of 3.000% convertible senior notes due 2029 in a private placement under the Securities Act of 1933. The company increased the size of the offering from the previously announced $1 billion and granted initial purchasers an option to buy up to an additional $200 million within a 13-day period beginning on the issuance date. The sale is expected to close on March 12, subject to customary closing conditions.
The announcement is significant as it outlines Duke Energy’s strategy for managing its debt and supporting general corporate purposes through this new note issuance. The net proceeds are expected to be approximately $1.29 billion, or up to $1.48 billion if the additional purchase option is exercised in full, after deducting discounts, commissions, and expenses.
According to Duke Energy, proceeds from this offering will be used primarily to repay at maturity $1.725 billion aggregate principal amount of outstanding 4.125% Convertible Senior Notes due April 15, 2026, including any cash amounts due upon conversion, as well as for general corporate purposes. The new convertible notes will mature on March 15, 2029, unless converted or repurchased earlier according to their terms.
The notes will bear interest at a fixed rate of 3.000% per year with payments made semiannually starting September 15, 2026. Holders may convert their notes under certain conditions before December 15, 2028; after that date until just before maturity they may convert at any time at the prevailing conversion rate.
The initial conversion rate is set at 6.2277 shares per $1,000 principal amount (an initial conversion price of about $160.57 per share), representing a premium of roughly 22.50% over Duke Energy’s last reported share price on March 9, 2026.
If Duke Energy undergoes a fundamental change as defined in the indenture governing these notes, holders can require repurchase for cash equal to principal plus accrued interest; certain changes may also trigger an increase in the conversion rate for conversions related to such events.
Duke Energy stated that many holders of its existing convertible notes use arbitrage strategies involving short positions in its common stock that could affect market prices during the observation period leading up to maturity and conversions.
This private offering targets qualified institutional buyers under Rule 144A and none of these securities have been registered under U.S. securities laws; they cannot be offered or sold without proper exemption or registration.
Duke Energy is one of America’s largest energy holding companies headquartered in Charlotte, North Carolina, serving millions across several states with both electric and natural gas utilities.
