Winston Score History

The full picture

Alliant Energy is a regulated utility company that provides electricity and natural gas to homes and businesses in the Midwest. It operates through two main subsidiaries — Interstate Power and Light in Iowa and Wisconsin Power and Light in Wisconsin — serving roughly 1 million electric customers and 420,000 natural gas customers across those two states.

Alliant Energy earns money by charging customers for the electricity and gas it delivers, with rates set and approved by state regulators. This regulatory model provides steady, predictable revenue but limits how much profit the company can earn. It operates exclusively in Iowa and Wisconsin, making it a mid-sized regional utility with an $18 billion market cap. Its main competitive moat is its government-granted monopoly in its service territories, which protects it from direct competition. The key growth driver is its ongoing investment in wind and solar energy, as both Iowa and Wisconsin push toward cleaner power sources, though rising construction costs and interest rates remain meaningful risks to its capital spending plans.

Cash watch

Alliant Energy Corporation has less than a year of cash at its current burn rate. Growth investors should watch for potential share dilution from future fundraising — that directly reduces your ownership.
