Alliant Energy Q2 2026 Earnings Overview
Alliant Energy Corporation (NASDAQ:LNT) posted second‑quarter 2026 earnings of $0.65 per share, falling short of the analyst consensus estimate of $0.69 by $0.04. Revenue for the quarter totaled $971 million, representing a 1% increase from $961 million in Q2 2025 but missing the consensus forecast of $987.98 million.
The utility reaffirmed its full‑year 2026 earnings guidance range of $3.36 to $3.46 per share, noting that results are currently trending in the upper half of this range. The midpoint of $3.41 is marginally below the analyst consensus of $3.42.
Drivers of Performance
The earnings uplift was driven by higher revenue requirements stemming from an expanding rate base at Interstate Power and Light Company and Wisconsin Power and Light Company, each contributing $0.09 per share. Additional earnings support came from higher equity earnings generated by corporate venture investments.
Offsetting Factors
Higher operating and maintenance expenses, primarily due to labor costs and planned maintenance activities, alongside increased financing and depreciation expenses, weighed on profitability. Unfavorable temperature conditions further reduced earnings by an estimated $0.03 per share.
Six‑Month Results and Outlook
For the six months ended June 30 2026, adjusted earnings per share were $1.47, down from $1.50 in the comparable prior‑year period. Alliant Energy expects a 60% load growth by 2031, with large‑customer load anticipated to materialize as forecast for 2026, driven by construction progress at three data‑center projects.
Management Commentary
