Ameren Corp stock (ISIN US0236081024) is drawing investor attention after Ameren Corporation announced a USD 900 million public offering of junior subordinated notes maturing in 2057, carrying a fixed 6.45% annual interest rate until 2032 per a release dated September 8, 2026.

Junior notes financing set at 6.45 percent

According to Seeking Alpha on September 8, 2026, Ameren Corporation priced junior subordinated notes with a total principal amount of USD 900 million, due in 2057, at 100.000% of par value.

The notes will accrue interest at a yearly rate of 6.450% from initial issuance until March 15, 2032, after which the rate will reset for each five-year period based on the five-year Treasury rate plus a spread of 1.868%, with a floor at 6.45%, as outlined in the prospectus supplement described by Seeking Alpha.

Use of proceeds and balance-sheet impact

Ameren plans to use the net proceeds from this junior notes offering for general corporate purposes, including repaying short-term debt, according to Seeking Alpha on September 8, 2026.

The structure of the notes, combining a long maturity to 2057 with an initial fixed coupon and later rate resets, gives Ameren long-term capital while preserving flexibility to align interest costs with future Treasury yields, as highlighted by GuruFocus on September 9, 2026.
