• Verizon or AT&T, but for electricity and natural gas.
• Union Pacific or Norfolk Southern, but for power lines and gas pipes.

• Electric Utility Services: Ameren generates, transmits, and distributes electricity to residential, commercial, and industrial customers primarily in Missouri and Illinois.
• Natural Gas Utility Services: Ameren distributes natural gas to residential, commercial, and industrial customers primarily in central and eastern Missouri.

Ameren (AEE) is a regulated utility company that provides electric and natural gas services primarily to end-users within its service territories in Missouri and Illinois. Therefore, it sells directly to a diverse customer base rather than primarily to other companies for resale.

Ameren serves the following major categories of customers:

• Residential Customers

  This category includes individual households and dwellings that use electricity and natural gas for personal consumption, such as lighting, heating, cooling, and operating household appliances. These customers typically have lower usage volumes per account but represent the largest number of customers.

• Commercial Customers

  This category encompasses various businesses and institutions, including retail stores, offices, restaurants, schools, hospitals, and small and medium-sized enterprises. Commercial customers generally have higher usage volumes than residential customers and their consumption patterns often vary based on business hours and operational needs.

• Industrial Customers

  This category includes large manufacturing plants, factories, and other heavy industries that require significant amounts of electricity and/or natural gas for their operations. These customers often have the highest individual usage volumes and demand, and their energy needs can be critical to their production processes.

The public company Ameren (symbol: AEE) faces several key business risks, primarily stemming from its highly regulated operating environment and significant capital investment needs.

1. Regulatory and Legislative Risks: Ameren operates in a heavily regulated industry, meaning changes in laws, regulations, and ratemaking decisions can significantly impact its operations, costs, and profitability. The company is subject to stringent regulations concerning emissions, discharges, and energy efficiency, which can increase operating costs or require substantial investment to comply with new standards. Regulatory pushback, project delays, and interest-rate pass-through lags also remain key risks to Ameren's growth model. Any changes in regulatory policies and ratemaking determinations, including those affecting cost recovery mechanisms, could cause actual results to differ materially from management expectations.
2. Financial Leverage and Rising Interest Costs: Ameren carries a high debt-to-equity ratio, which indicates elevated financial leverage and exposes the company to greater risk in a rising interest rate environment. Higher interest expenses are actively increasing losses at the Ameren Parent level and can be a drag on net income. Given Ameren's substantial infrastructure investment plans, its reliance on debt to finance these projects makes it vulnerable to fluctuations in capital market conditions.
3. Cybersecurity and Operational Risks: Ameren faces threats from cyberattacks and data security risks, which could disrupt operational control of its energy centers and compromise sensitive information. The increasing frequency and severity of such attacks in the utility industry necessitate robust cybersecurity measures and contingency planning to protect against potential losses.

The increasing adoption and declining costs of distributed energy resources (DERs), particularly rooftop solar combined with battery storage systems, represent a clear emerging threat. As these technologies become more affordable and efficient, a growing number of Ameren's customers (residential, commercial, and industrial) may choose to generate and store their own electricity, reducing their reliance on grid-supplied power. This trend can lead to decreased electricity sales volumes for Ameren, impacting revenue growth and potentially necessitating higher rates for remaining customers to cover fixed infrastructure costs, challenging the traditional utility business model.

Ameren (symbol: AEE) primarily operates as a rate-regulated electric and natural gas utility company, serving customers across Missouri and Illinois. Their main products and services include electric generation, transmission, and distribution, as well as natural gas distribution.

Addressable Market Sizes:

• Electric Utility Services (Generation, Transmission, and Distribution):
  • The U.S. electric power transmission and distribution market was valued at approximately $89.9 billion in 2024, with projections to reach $110.4 billion by 2032.
  • The U.S. electric distribution utility market is anticipated to surpass $79.5 billion by 2032.
  • Region: U.S.
• Natural Gas Distribution Services:
  • The U.S. natural gas distribution market was valued at $170.0 billion in 2024, and is expected to grow to $186.0 billion by 2032.
  • The Natural Gas Distribution industry in the United States is estimated to have generated $222.5 billion in revenue in 2025.
  • Region: U.S.

Here are 3-5 expected drivers of future revenue growth for Ameren (AEE) over the next 2-3 years:

1. Infrastructure Investments and Rate Base Growth: Ameren is undertaking significant infrastructure investments to modernize and strengthen its energy grid, expand transmission capabilities, and develop new energy resources. The company anticipates a robust 9.2% compound annual rate base growth from 2025 through 2029, which forms a primary basis for revenue expansion through regulatory mechanisms. Ameren's long-term investment pipeline includes over $68 billion in regulated infrastructure projects from 2025 through 2034.
2. Implementation of New Electric Service Rates: New electric service rates, particularly in Missouri, are a direct driver of increased revenue. For example, new electric service rates in Missouri became effective on June 1, 2025, and contributed to revenue increases in Q3 2025. These rate adjustments are crucial for recovering the costs of infrastructure investments.
3. Growth in Data Center Demand: Ameren is experiencing robust demand from data center developers, with agreements expanding to 3 gigawatts from 2.3 gigawatts. This expanding demand is a significant driver of future electricity sales growth, with expectations of 1 gigawatt of new load from data center customers by the end of 2029 in Ameren Missouri's service territory.
4. Expansion of Renewable Energy Generation: The company is strategically focused on expanding its renewable energy portfolio and plans to add approximately 10 gigawatts of generation capacity by 2035. Investments in cleaner energy sources contribute to revenue growth as Ameren transitions its energy generation mix.
5. Strong Sales and Economic Growth: Beyond specific data center opportunities, Ameren anticipates general strong sales and economic growth across all customer classes within its service territories, particularly in Ameren Missouri. This organic growth in electricity and natural gas demand supports overall revenue increases.
