ALLIANT ENERGY CORP · 2026-10-30 · Importance 52 · Surprise 56 · From source text

Alliant Energy consolidated net income for the three months ended September 30, 2026, was $398 million, up $117 million from $281 million in 2025; diluted EPS increased to $1.52 from $1.09. Utilities and Corporate Services net income rose $120 million to $412 million, with diluted EPS increasing to $1.58 from $1.13. Management attributed the increase primarily to income-tax timing, higher revenue requirements from IPL and WPL capital investments, higher allowance for funds used during construction, and higher retail electric sales. Higher operation and maintenance, financing, and depreciation expenses partially offset those gains.
