Duke Energy Announces Proposed \$1 Billion Convertible Senior Notes Offering – What Investors Need to Know

Charlotte, N.C. – March 9, 2026: Duke Energy Corporation (NYSE: DUK), one of America’s largest energy holding companies, has announced its intention to offer \$1 billion in aggregate principal amount of convertible senior notes due 2029 in a private placement. This move, subject to market and other conditions, has implications that investors should carefully consider.

Key Details of the Offering

• Offering Size and Option: Duke Energy intends to issue \$1 billion of convertible senior notes, with an option for initial purchasers to buy up to an additional \$150 million in notes within a 13-day window from the initial issuance.
• Purpose of Proceeds: The net proceeds will be used to repay at maturity \$1.725 billion in existing 4.125% Convertible Senior Notes due April 15, 2026, as well as for general corporate purposes.
• Structure: The new convertible notes are direct, unsecured, and unsubordinated obligations of Duke Energy. They will be convertible at the option of noteholders under certain conditions and during specific periods, with interest payable semiannually in arrears.
• Settlement of Conversions: Upon conversion, Duke Energy will pay cash up to the principal amount being converted, and, at its election, may pay or deliver additional cash, common shares, or a combination thereof for any excess conversion obligation.
• Private Placement: The offering is only available to qualified institutional buyers under Rule 144A of the Securities Act. The notes and any shares issued upon conversion will not be registered under the Securities Act or state securities laws unless otherwise registered in the future.

Shareholder-Relevant and Price-Sensitive Information

• Potential Share Price Impact from Arbitrage Activity:

  The final observation period for the existing convertible notes starts on March 9, 2026. Many holders of these notes use convertible arbitrage strategies and maintain short positions in Duke Energy’s common stock. As the existing notes mature or are converted, these investors may close their short positions by purchasing Duke Energy common stock or unwinding related derivatives. This activity could increase (or reduce the size of any decrease in) the market price of Duke Energy’s common stock during the observation period. A higher market price could effectively raise the conversion price for the new notes, making current trading in DUK shares potentially more volatile and price-sensitive.

• Forward-Looking Risks:

  The company outlines numerous forward-looking risks that could materially impact future results and, by extension, the value of DUK shares. These include:

  • Ability to implement business strategy, meet load growth, modernize the grid/fleet, and reduce carbon emissions while balancing reliability and costs.
  • Regulatory, legislative, and legal risks related to environmental compliance, cost recovery, coal ash remediation, and climate change.
  • Operational risks from severe weather, supply chain disruptions, cybersecurity threats, nuclear facility operations, and catastrophic events such as pandemics or natural disasters.
  • Financial risks, including ability to obtain financing on favorable terms, interest rate fluctuations, and pension funding requirements.
  • Market risks, such as changes in customer demand, increased competition, evolving technology, and changing investor or stakeholder expectations.
  • Risks around construction, development, and completion of capital projects (cost, timing, regulatory approval, labor, etc.).
  • Risks related to acquisition/disposition, activist shareholders, and potential impairment of goodwill or investments.

  These factors, individually or collectively, could affect Duke Energy’s financial health, share price, dividend policy, and ability to execute its strategy.
