Electric revenues were $6.439 billion, down from $6.581 billion, while natural gas revenues were $1.061 billion, down from $1.376 billion. Electric margins increased $66 million to $4.627 billion, while natural gas margins declined $13 million to $706 million. Revenue declines primarily reflected lower natural gas prices and pass-through recoveries, lower off-system sales and capacity revenues, and milder weather. Earnings benefited from infrastructure investment, higher recognized returns at Ameren Illinois Electric Distribution, Ameren Missouri’s July 2023 rate increase, lower certain operating expenses, and higher pension-related income.
Cash flow from operations exceeded capital expenditures by approximately $1.033 billion, but was below capital expenditures plus common dividends of $662 million. The company therefore relied on debt, equity issuance, and other financing sources to fund investment and shareholder distributions.
Material changes versus the prior comparable period
- Net income attributable to common shareholders increased 7% despite a 6% decline in total operating revenues.
- Ameren Transmission earnings increased primarily because of higher recoverable expenses and a 10% increase in rate base.
- Ameren Illinois Electric Distribution earnings increased with higher rate base investment and a higher recognized return on equity.
- Ameren Missouri earnings declined $17 million, principally because of milder weather, lower retail sales, lower off-system sales and capacity revenues, and lower MEEIA performance incentives.
- Other operations and maintenance expense declined $71 million, while depreciation and amortization increased $98 million and interest expense increased $80 million due largely to a larger asset base, higher debt, and higher interest rates.
- Rate base increased to $25.8 billion from $23.6 billion, led by electric transmission and distribution investment.
- Ameren issued $2.295 billion of long-term debt and $346 million of common stock in 2023. Consolidated long-term debt maturities totaled $849 million in 2024, including $450 million at the parent.
- Ameren increased its annualized common dividend from $2.52 per share to $2.68 per share in February 2024. Management expects a dividend payout ratio of 55% to 65% over the next several years.
Guidance, outlook, risks, contingencies, and unusual items
- Management projects $21.0 billion to $22.8 billion of capital expenditures from 2024 through 2028, including up to $13.5 billion at Ameren Missouri, $7.6 billion at Ameren Illinois, and $1.7 billion at ATXI. The filing states that cash used for planned capital expenditures and dividends is expected to exceed operating cash flow over the next several years.
- Ameren Missouri expects approximately $22 million of 2024 earnings benefit from the June 2023 electric rate order. The filing also includes a proposed MEEIA plan for 2025 through 2027, but approval and resulting incentives remain uncertain.
- Ameren Illinois’ electric distribution MYRP approved revenue requirements of $1.162 billion, $1.210 billion, $1.242 billion, and $1.255 billion for 2024 through 2027. Ameren Illinois is seeking rehearing and has appealed the order; its proposed rehearing amounts were higher, at $1.214 billion, $1.300 billion, $1.371 billion, and $1.420 billion.
- Ameren Illinois’ QIP for natural gas infrastructure expired in December 2023, increasing regulatory lag. A proceeding could disallow approximately $53 million of 2020 capital investments, with a potential over-recovery of approximately $3 million.
- Rush Island Energy Center is scheduled to retire by October 15, 2024. Ameren Missouri petitioned for authorization to securitize approximately $519 million of retirement-related costs. The facility had a $530 million net plant balance classified as plant to be abandoned at December 31, 2023. Failure to obtain recovery could result in a material adverse effect.
- Environmental, regulatory, and litigation exposure remains significant, including Clean Air Act litigation, potential additional mitigation costs, coal-combustion-residual compliance, emissions rules, and remediation obligations. Ameren Illinois estimated remaining obligations for three former manufactured-gas-plant sites at $51 million to $96 million and recorded the low end of that range as a liability.
- Ameren Missouri’s 2023 integrated resource plan targets 2,800 MW of additional renewable generation by 2030, 400 MW of battery storage by 2030, retirement of all coal-fired generation by 2042, and potential additions of natural-gas and other clean dispatchable resources. These plans depend on regulatory approvals, supply-chain availability, technology costs, and timely cost recovery.
- Ameren targets a 60% reduction in carbon emissions by 2030, an 85% reduction by 2040, and net-zero carbon emissions by 2045, based on 2005 levels. Achievement depends on regulatory policy, technology, capital availability, and system reliability.
- The filing states that no cybersecurity events materially affected or were reasonably likely to materially affect the company as of the filing date.
- Regulatory accounting is material: Ameren reported approximately $2.2 billion of regulatory assets and $5.6 billion of regulatory liabilities at December 31, 2023. Recovery and refund assumptions are subject to regulatory decisions and prudence reviews.
Most important facts for investors to verify
- Outcome and timing of Ameren Missouri’s Rush Island securitization petition and any additional environmental mitigation requirements.

- Whether projected capital expenditures can be recovered through rates without adverse effects from regulatory lag, reconciliation caps, or cost disallowances.
- Debt refinancing needs, interest-rate sensitivity, credit ratings, and the planned equity issuances of approximately $300 million in 2024 and $600 million annually from 2025 through 2028.
- Progress, cost, and regulatory approval status of renewable generation, battery storage, transmission, and natural-gas projects.
- Actual operating cash flow relative to capital expenditures and dividends, particularly as the company expects negative free cash flow under its stated definition over the next several years.
- Exposure to environmental remediation, coal-ash compliance, emissions regulation, nuclear operations, fuel supply, severe weather, cybersecurity, and commodity-price volatility.
