Core business and utility operations

Ameren’s business centers on rate-regulated generation, transmission and distribution of electricity and distribution of natural gas. Ameren Missouri provides electric generation, transmission and distribution services, as well as natural gas distribution service, to customers in central and eastern Missouri, including the greater St. Louis area. Ameren Missouri has been providing electric and gas service for more than 100 years and reports that its electric rates are among the lowest in the nation. Ameren Illinois provides electric transmission and distribution service and natural gas distribution service throughout central and southern Illinois, serving more than 1.2 million electric and over 800,000 natural gas customers across more than 1,200 communities.

Ameren Transmission Company of Illinois develops, owns and operates rate-regulated regional electric transmission projects in the Midcontinent Independent System Operator, Inc. (MISO) region. Through these businesses, Ameren owns and operates networks that move energy from generation resources to homes and businesses, under regulatory frameworks overseen by state commissions and federal regulators.

Service territory and customer base

The company’s utility subsidiaries operate in a large, contiguous territory across Missouri and Illinois. Ameren Missouri’s service area covers approximately 60 counties and more than 500 communities in central and eastern Missouri. Ameren Illinois’ service territory spans about 43,700 square miles and more than 1,200 communities in central and southern Illinois. Together, these territories form a bi-state footprint in which Ameren’s operations support millions of residential, commercial and industrial customers.

Within this footprint, Ameren’s services underpin both everyday residential energy use and the needs of large businesses. Recent regulatory approvals, such as the Missouri Public Service Commission’s decision on Ameren Missouri’s large load customer rate structure, highlight the company’s focus on serving high-usage customers, including data centers and advanced manufacturing businesses, while maintaining protections for other customer classes.

Regulation and rate structures

Ameren’s utilities operate under rate regulation by state commissions, including the Missouri Public Service Commission and the Illinois Commerce Commission, and under federal oversight for transmission activities. Ameren Missouri uses mechanisms such as plant-in-service accounting and participates in proceedings that establish electric service revenue requirements and allowed returns on equity. Ameren Illinois utilizes multi-year rate plans for electric distribution service and participates in performance-based frameworks for energy-efficiency programs.

In Missouri, Ameren obtained approval for a large load customer rate plan that applies to new facilities with monthly load demand of at least 75 megawatts and to existing customers expanding load by that amount. Under this structure, large customers enter into long-term electric service agreements with minimum terms, demand charge obligations on a percentage of contracted capacity, collateral requirements, and defined exit fees. The plan also incorporates an earnings sharing mechanism that returns a portion of earnings above a specified return on equity level to retail electric customers.

Generation mix and infrastructure investment

Ameren Missouri provides electric generation as part of a balanced resource portfolio that includes dispatchable and intermittent resources. The company has described a goal for a balanced energy mix with a significant share from on-demand resources and a portion from intermittent sources. Ameren Missouri’s resource planning includes investments in dispatchable generation, energy storage and electric infrastructure to support reliability and economic growth.

Recent announcements include plans for the Reform Renewable Energy Center, a proposed 250-megawatt solar facility adjacent to the Callaway Energy Center in central Missouri. The project is intended to add low-cost, locally generated energy, support thousands of homes, and create construction and permanent jobs, subject to regulatory approvals. Ameren Missouri has also outlined projects such as Castle Bluff Energy Center for backup power during peak demand and the planned Big Hollow Energy Center, a hybrid natural gas and battery storage facility, along with multiple solar projects designed to expand its renewable capacity.

Transmission and regional role

Through Ameren Transmission Company of Illinois, the company develops, owns and operates regional electric transmission projects that are integrated into the MISO grid. These projects are rate-regulated and are intended to support reliability, accommodate new generation resources and enable economic development within the region. Transmission operations are subject to Federal Energy Regulatory Commission (FERC) oversight, including determinations on allowed base returns on equity and treatment of certain tax and regulatory items.

Capital structure, liquidity and financing

Ameren supports its utility capital programs through a combination of debt and equity financing. Its subsidiaries, such as Ameren Illinois, issue long-term debt instruments including first mortgage bonds, and Ameren maintains revolving credit facilities and an equity distribution program. For example, Ameren Illinois has issued first mortgage bonds due 2055 and has used proceeds to refinance short-term debt. Ameren and its utility subsidiaries have entered into amended and restated multi-year, senior unsecured revolving credit agreements that provide multi-billion-dollar aggregate credit capacity, with covenants tied to consolidated debt ratios and other customary terms.

At the holding company level, Ameren has an equity distribution program under which it may sell shares of common stock from time to time through designated sales agents and forward purchasers. Amendments to this program have increased the aggregate gross sales price authorized for issuance, providing additional flexibility to fund infrastructure investments and manage the balance sheet.

Economic development and community impact

Ameren’s operations have a documented economic impact in Missouri and Illinois. A study conducted by HR&A Advisors and commissioned by Ameren estimated that the company’s activities generate more than $20.7 billion in annual economic output in the bi-state region. The study attributes this impact to direct spending on payroll, capital equipment and supplier services, as well as indirect and induced effects as businesses and consumers spend related income.

According to the study highlights, Ameren’s annual economic activity supports tens of thousands of jobs, involves substantial purchases from in-state suppliers, and contributes significant tax revenues to state and local governments. Ameren also reports philanthropic support for critical community needs. In addition, Ameren provides technical assistance to new, expanding and relocating businesses, and has been associated with numerous economic development projects that have created thousands of jobs and driven billions of dollars in capital investment across its service territories.

Recent filings describe board appointments, including the election of a director with extensive information systems and cybersecurity experience, and leadership changes in senior executive roles such as chief financial officer, group president for utilities, and presidents of key subsidiaries. These changes are intended, according to company statements, to support consistent operating performance, strengthen governance, and enhance oversight of areas such as risk management, digital technology and utility operations.

Dividends and shareholder returns framework

Ameren’s board of directors has declared regular quarterly cash dividends on its common stock, as well as on preferred stock of its utility subsidiaries Ameren Missouri and Ameren Illinois. Dividend declarations are communicated through press releases and reflect the company’s approach to returning capital to shareholders while funding its regulated utility investment plans. The timing and amount of dividends are determined by the boards of the respective entities and disclosed publicly.

Financial reporting and transparency

These materials include statements of income, balance sheets and cash flow statements, along with management commentary on results and guidance ranges for future earnings per share.
