Company Description
Alliant Energy Corporation (NASDAQ: LNT) is a regulated energy-services company whose primary focus is providing electricity and natural gas to customers in the Midwest. According to company disclosures, its utility subsidiaries serve approximately 1,000,000 to 1,010,000 electric customers and about 430,000 natural gas customers. Alliant Energy is headquartered in Madison, Wisconsin and is a component of the S&P 500 index. Its common stock trades on the Nasdaq Global Select Market under the symbol LNT.
The company operates mainly through two public utility subsidiaries: Interstate Power and Light Company (IPL), based in Cedar Rapids, Iowa, and Wisconsin Power and Light Company (WPL), based in Madison, Wisconsin. These utilities provide regulated electric and natural gas service to customers across Iowa and Wisconsin. Alliant Energy has described the provision of regulated electricity and natural gas service in these territories as its primary business focus.
Alliant Energy also identifies itself as an energy-services provider with a core purpose to serve customers and build stronger communities. Its stated mission is to deliver energy solutions and exceptional service that customers and communities count on, with an emphasis on safety, efficiency and responsibility. In public communications, the company highlights a balanced mix of energy sources and investments in solar generation and energy storage as part of its capital plans, as well as the importance of maintaining safe and reliable service for all customers while meeting growing demand, including demand from data centers.
Beyond its utility operations, Alliant Energy has non-utility activities held through Alliant Energy Finance, LLC, the parent company of its non-utility operations. The company also notes an ownership interest in American Transmission Company (ATC) through ATC holdings, which contributes to its earnings profile. However, its regulated utility subsidiaries remain the primary drivers of its business and financial results.
Alliant Energy’s customer base includes residential, commercial and industrial users within its Iowa and Wisconsin service territories. Company statements reference contracted demand from data centers in the IPL and WPL service areas, reflecting incremental large-load growth. The company has linked higher revenue requirements and capital investments to projects such as solar generation and energy storage, and to infrastructure needed to serve new and existing customers.
Alliant Energy emphasizes a long record of returning cash to shareholders through dividends. The Board of Directors has declared quarterly cash dividends for many decades, and the company reports that dividends on its common stock have been paid for more than 320 consecutive quarters since 1946. Alliant Energy is recognized as a member of the S&P 500 Dividend Aristocrats Index, reflecting its history of dividend payments and increases over an extended period.
In addition to its S&P 500 membership, Alliant Energy reports that it is included in Bloomberg’s Gender-Equality Index. The company also publishes a Corporate Responsibility Report that discusses sustainability data, a balanced mix of energy sources, employee engagement and community impact, including financial contributions and volunteer hours provided by the company, its employees, retirees and its charitable foundation.
Alliant Energy and its utility subsidiaries access capital markets to support their regulated operations and capital expenditure plans. Recent disclosures describe public offerings of long-dated debentures by WPL and senior debentures by IPL, as well as junior subordinated notes issued by Alliant Energy Corporation. The proceeds of these offerings are generally intended for purposes such as reducing outstanding commercial paper, retiring long-term debt and funding general corporate purposes, including capital investments.
From a regulatory standpoint, Alliant Energy’s utilities operate under state commissions in their respective jurisdictions. Company communications reference rate reviews and authorized base rate increases for IPL and WPL that support recovery of and return on capital investments, including investments in solar generation and energy storage. The company also discusses the role of regulatory approvals, rate design and assumptions such as normal temperatures and stable economic conditions in shaping its earnings guidance.
Alliant Energy’s public statements outline several factors that can influence its financial performance, including weather effects on utility sales, customer-owned generation, energy efficiency, economic conditions in its service territories, fuel and purchased power costs, access to transmission capacity, and the timing and cost of capital projects. The company also identifies potential impacts from federal and state regulatory actions, tax law changes, cybersecurity risks, supply chain conditions, inflation, interest rates and access to capital markets.
In its Corporate Responsibility and other communications, Alliant Energy highlights its role in supporting community development and economic growth. Examples include references to data center development in its service areas and local investments in what it describes as smart energy solutions. The company links these initiatives to broader goals of building stronger, more resilient communities and providing what it characterizes as measurable value grounded in trust and transparency.
Alliant Energy’s governance structure includes a Board of Directors that oversees corporate strategy, financial policy and risk management. Public filings and press releases describe Board actions such as the appointment of independent directors and changes in leadership roles at subsidiary utilities. These governance disclosures are part of the company’s regulatory reporting obligations and provide context for investors regarding oversight of its long-term strategy and operations.
Overall, Alliant Energy Corporation presents itself as a regulated utility holding company focused on providing electric and natural gas service in Iowa and Wisconsin, supported by long-term capital investment plans, a long-standing dividend track record, and stated commitments to safety, reliability, community engagement and corporate responsibility.
