Alliant Energy Corporation has announced U.S. generally accepted accounting principles consolidated and non-GAAP consolidated unaudited earnings per share (EPS) for the three months ended June 30 as follows:

Utilities and Corporate Services - Alliant Energy’s Utilities and Alliant Energy Corporate Services, Inc. (Corporate Services) operations generated $0.74 per share of GAAP EPS in the second quarter of 2025, which was $0.41 per share higher than the second quarter of 2024. The primary drivers of higher EPS were items in 2024 not normally associated with ongoing operations and described below in the discussion of non-GAAP adjustments, higher revenue requirements from capital investments, and estimated temperature impacts on retail electric and gas sales. These items were partially offset by higher depreciation and financing expenses.

Non-utility and Parent - Alliant Energy’s Non-utility and Parent operations generated ($0.10) per share of GAAP EPS in the second quarter of 2025, which was $0.07 per share lower than the second quarter of 2024. The lower EPS was primarily driven by lower equity income from corporate venture investments, higher financing expense and timing of income taxes.

“Our solid financial performance this quarter underscores the resilience of our regulated utility model and our ability to advance key operational and strategic initiatives while positioning us for long-term success,” according to Lisa Barton, Alliant Energy President and CEO.
