Reading
The figures above are taken directly from filings with the U.S. Securities and Exchange Commission. The reading below was generated by a local language model from only those figures; it introduces no numbers of its own. It is not investment advice.
Alliant Energy Corp (LNT) operates primarily in the regulated utilities sector, with a scale evident from its substantial total assets of $24.99B as of the latest annual filing. The company’s revenue has grown modestly at a 1.0% annual pace over the past 17 years, reaching $4.36B in 2025. Despite this relatively slow growth, net income has expanded significantly from 8.4% to 18.6% of revenue during the same period.
The multi-year trajectory reveals a company that has managed to enhance profitability while maintaining steady, albeit modest, revenue growth. Notably, the latest annual figures show an increase in both operating income ($1.02B) and net income ($810.0M) compared to the previous year. However, total assets have slightly decreased, and cash & equivalents have declined from $556.0M to $556.0M annually.
In the most recent quarterly filing, revenue stood at $1.18B, with operating income of $249.0M and net income of $224.0M — all lower than their annual counterparts but still demonstrating a seasonal pattern typical in utility businesses. Investors should monitor the company’s ability to sustain profitability amidst modest revenue growth, as well as its cash management given the fluctuations observed between annual and quarterly figures. The next filing will likely reveal whether Alliant Energy can continue improving net margins while managing asset levels effectively.
