Alliant Energy Corp

Alliant Energy posted a solid first quarter for 2026, with non-GAAP EPS of $0.82 edging past the $0.79 consensus estimate by 3.96%, while revenue of $1.18 billion beat expectations by 6.40% and rose 5.0% year over year from $1.13 billion. The top-line strength was anchored by higher electric and gas utility revenues, though operating income dipped to $249.00 million from $257.00 million as increased depreciation, interest expense, and planned maintenance costs offset those gains. The more compelling headline, however, may be strategic: Alliant signed a new roughly 370 MW electric service agreement in Iowa for data center demand, lifting its total contracted data center load to approximately 3.4 GW across five agreements, a demand signal that analysts see as a meaningful long-term growth lever. Some observers have flagged a one-time tax benefit in the GAAP result as a potential earnings quality concern, though the company's reaffirmed 2026 ongoing EPS guidance range of $3.36 to $3.46 per share suggests management views the underlying business as firmly on track.
