Alliant Energy Corp

Alliant Energy delivered a clean beat across both top and bottom lines in the second quarter of 2025, as regulatory-approved rate increases and a growing renewable energy asset base helped the Madison, Wisconsin-based utility clear Wall Street's expectations with room to spare. The company posted GAAP EPS of $0.68, beating the $0.64 consensus estimate by 6.00%, while revenue of $961.00 million came in 4.81% ahead of the $916.93 million forecast and 7.5% above the year-ago period. The single most material driver was higher revenue requirements from capital investments, which contributed $0.19 per share, as both Interstate Power and Light and Wisconsin Power and Light benefited from authorized base rate increases tied to ongoing buildout of solar generation and energy storage capacity. Net income attributable to shareholders reached $174.00 million, compared with $87.00 million a year ago, though the prior-year figure was weighed down by $59.00 million in pre-tax non-cash charges that did not recur. Shares reached an all-time high near the filing date, reflecting investor confidence in the company's clean energy transition. Management reaffirmed full-year 2025 ongoing EPS guidance of $3.15 to $3.25, underpinned by normal temperature assumptions and continued execution on its capital investment program.
