Alliant Energy Stock Earnings Reports

Alliant Energy delivered solid first-quarter 2026 results (GAAP $0.87, ongoing $0.82 per share) and reaffirmed full-year 2026 earnings guidance. Mild temperatures modestly reduced margins, but core drivers included higher revenue requirements and AFUDC from Iowa and Wisconsin capital investments, partially offset by higher O&M, depreciation and financing costs. The company reported significant data center progress: five executed data center agreements totaling ~3.4 GW of contracted demand (three projects under construction) and a newly announced 370 MW electric service agreement in Iowa. To support growth, Alliant has contracted for up to 1.1 GW of simple-cycle natural gas capacity (with an agreement to build a facility through a counterparty) and plans to rely primarily on batteries and combustion turbines for capacity additions, preserving flexibility to convert to combined cycles if needed. Regulatory progress included approvals for new wind projects (Iowa blended ROE ~9.8% for up to 1 GW; 153 MW Ventre North in Wisconsin) and ongoing dockets for CTs and data center-related filings. On financing, the company refinanced $1.1 billion of 2026 maturities, raised ~$1.3 billion of planned common equity via forward agreements (out of ~$2.4 billion needed through 2029), filed a new $1 billion ATM program, and plans up to $800 million of additional 2026 long-term issuances. IPL received an S&P upgrade to A-. Management expects 7%+ compound annual EPS growth for 2027–2029, will provide a refreshed Iowa resource plan and EPS/growth update at the Q3 call/EEI, and continues to emphasize customer-funded interconnection and affordability for existing customers.
