• Ameren remains focused on disciplined cost management and strategic capital allocation.
• We believe that the final disposition of these proceedings, except as otherwise disclosed in the notes to our financial statements in this report and in the Form 10-K, will not have a material adverse effect on our results of operations, financial position, or liquidity.

Industry Context

The utility industry is undergoing a significant transformation towards clean energy, driven by state mandates and environmental goals. Ameren's strategic plan aligns with this trend, targeting net-zero carbon emissions by 2045 through substantial investments in renewable generation, battery storage, and natural gas-fired facilities. The company is also actively addressing the growing demand from high-load customers, such as data centers, which is a key trend for utilities in regions with favorable energy costs and infrastructure. Regulatory changes, such as Missouri Senate Bill 4 and the OBBBA, reflect ongoing legislative efforts to shape the future of energy infrastructure and financing, impacting cost recovery and investment incentives across the sector. The appeals against FERC's ROE orders highlight the continuous regulatory scrutiny on transmission rates, a common challenge for utilities operating within RTOs like MISO.

Comparison to Industry Standards

• Ameren's target of net-zero carbon emissions by 2045, with interim goals of 60% reduction by 2030 and 85% by 2040 (from 2005 levels), is broadly in line with or more ambitious than many peers in the U.S. utility sector, which are also setting aggressive decarbonization targets.
• The planned capital expenditures of up to $27.4 billion from 2025-2029 for infrastructure upgrades, including transmission and distribution systems, are consistent with the industry-wide trend of significant grid modernization and reliability investments, often driven by aging infrastructure and the integration of new energy sources.
• Ameren Missouri's strategy to add 3,200 MW of renewable generation and 1,000 MW of battery storage by 2030, as part of its Preferred Resource Plan, reflects a strong commitment to renewable energy deployment, comparable to leading utilities actively expanding their clean energy portfolios.
• The company's dividend payout ratio expectation of 55% to 65% of annual earnings is within the typical range for mature, regulated utility companies, which often offer stable and predictable dividends.
• The allowed ROE of 9.98% for FERC-regulated transmission rate base, as per the October 2024 FERC order, is a common point of contention and appeal across MISO transmission owners, indicating that Ameren's position is not unique in seeking higher returns on transmission investments compared to the FERC's determination.

Corporate Governance

Legal Proceedings

• Ameren Illinois filed an appeal of the ICC's December 2024 order to the Illinois Appellate Court for the Fifth Judicial District to revise the allowed ROE and to include an asset associated with other postretirement benefits in the rate base.
