Ameren

Interest charges increased $22 million and $43 million in the three and six months ended June 30, 2025, respectively, compared with the year-ago periods. In addition to changes by segments discussed below, interest charges increased $14 million and $33 million respectively, at Ameren (parent), because of increased levels of short-term borrowings that increased interest charges by $6 million and $26 million, respectively. Additionally, interest charges increased $7 million in the three and six months ended June 30, 2025, at Ameren (parent), due to a long-term debt issuance in March 2025 offset by the repayment of a senior unsecured note in September 2024.

Ameren Missouri

Interest charges increased $7 million and $5 million in the three and six months ended June 30, 2025, respectively, compared with the year-ago periods. Interest charges increased by $12 million and $20 million, respectively, primarily due to the issuances of long-term debt in April 2024, October 2024, and April 2025. Additionally, interest charges increased by $6 million and $12 million, respectively, due to the December 2024 issuance of securitized utility tariff bonds associated with the retirement of the Rush Island Energy Center, see Note 14 - Commitments and Contingencies under Part II, Item 8, in the Form 10-K for more information.

The above increases were offset by interest charges that reflected a deferral to a regulatory asset of interest associated with investments in eligible property, plant and equipment not yet reflected in rates pursuant to PISA and RESRAM, which decreased interest charges by $10 million and $27 million, respectively.
