The latest announcement is out from Duke Energy ( (DUK) ).
On March 6, 2026, Duke Energy Indiana completed a $500 million issuance and sale of First Mortgage Bonds, Series DDDD, carrying a 4.95% coupon and maturing March 15, 2036, under an underwriting agreement signed March 4, 2026. The bonds, issued at a discount under the company’s long-standing mortgage indenture with Deutsche Bank National Trust Company as trustee, reinforce Duke Energy Indiana’s access to long-term capital markets to support its regulated utility operations and were registered on Form S-3 with related legal opinions filed to validate the securities for investors.
The transaction, backed by the utility’s first mortgage lien, may lower the company’s overall financing costs compared with shorter-term funding and helps lock in fixed-rate debt in the current interest-rate environment. For bondholders and other stakeholders, the secured nature of the issue and the established indenture framework provide additional structural protections, while the sizable tranche underscores continuing institutional demand for investment-grade regulated utility debt.
The most recent analyst rating on (DUK) stock is a Hold with a $139.00 price target. To see the full list of analyst forecasts on Duke Energy stock, see the DUK Stock Forecast page.
