Wisconsin-based Alliant Energy Corporation (LNT) is a utility holding company that provides regulated electricity and natural gas services. Valued at a market cap of $15.1 billion, the company primarily operates through two wholly owned subsidiaries, which are Interstate Power and Light Company (IPL) and Wisconsin Power and Light Company (WPL).
Companies valued at over $10 billion are typically classified as “large-cap stocks,” and Alliant fits the label perfectly with its market cap exceeding this threshold. The public utility company provides regulated energy service to approximately one million electric and 425,000 natural gas retail customers across Iowa and Wisconsin.
