Key Details

• Offering size: $1,300,000,000 principal amount (upsized from $1,000,000,000).
• Coupon: 3.000% interest rate.
• Maturity: Due in 2029 (convertible senior notes).
• Placement type: Private placement (not a registered public offering); press release filed 03/10/2026.

Why It Matters
This transaction raises a significant amount of capital for Duke Energy and adds fixed-rate debt to the capital structure through convertible notes. Because these notes are convertible into equity, they carry potential dilution for shareholders if conversions occur. The 3.000% coupon and 2029 maturity date affect the company’s future interest obligations and debt maturity profile. Retail investors should note the size, interest cost, and convertible feature when assessing Duke Energy’s leverage and potential share dilution.
