Interest charges were comparable between periods.

Ameren Missouri

Interest charges decreased $2 million in the three months ended March 31, 2025, compared with the year-ago period. Interest charges 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 $17 million. Interest charges also decreased by $3 million due to the maturity of $350 million of senior secured notes bearing a 3.5% interest rate in April 2024 that were repaid with cash on hand.

The above decreases were largely offset by an increase in interest charges because of issuances of long-term debt in January 2024, April 2024, October
