Alliant Energy Corporation reported relatively stable results for the six months ended June 30, 2026. Consolidated revenues were $2.155 billion versus $2.088 billion a year earlier, and net income attributable to common shareowners was $394 million compared with $387 million. Diluted EPS was $1.52, slightly above $1.50 in 2025, supported in part by a larger income tax benefit driven by renewable tax credits and changes in state apportionment.
Capital spending remained heavy, with $1.022 billion in construction and acquisition expenditures in the first half, funded through operating cash flow of $481 million, increased commercial paper, and a $400 million term loan. Cash declined to $25 million from $556 million at year-end.

Total revenues increased to $1,184 million from $1,128 million as both electric and gas utility revenues grew, partly offset by lower other utility revenues after IPL exited its steam business.
Operating income eased to $249 million from $257 million as higher fuel, gas, depreciation, and operations and maintenance costs more than offset revenue growth. IPL’s quarterly net income declined to $94 million from $110 million, while WPL’s net income increased to $117 million from $110 million.
Alliant generated $368 million of operating cash flow versus $249 million a year earlier and invested $414 million, mainly in utility projects.
