(a)For the three and six months ended June 30, 2026, the non-service cost components of net periodic benefit income were adjusted by amounts deferred of $(20) million and $(40) million, respectively, due to a regulatory tracking mechanism for the difference between the level of such costs incurred by Ameren Missouri under GAAP and the level of such costs included in rates. The deferral was $(16) million and $(32) million, respectively, for the three and six months ended June 30, 2025. See Note 11 – Retirement Benefits for additional information.
(b)See Note 4 – Long-term Debt and Equity Financings above and Note 5 – Long-term Debt and Equity Financings under Part II, Item 8, of the Form 10-K for additional information on Ameren (parent)’s repurchase of Ameren Missouri’s senior secured notes and first mortgage bonds and Ameren Illinois’ first mortgage bonds that were accounted for as a debt extinguishment.
