Alliant Energy (LNT) is trading higher after reporting first-quarter 2026 results and reiterating full-year profit guidance. The company posted Q1 2026 GAAP EPS of $0.87 (up from $0.83 in Q1 2025) and reaffirmed 2026 consolidated ongoing EPS guidance of $3.36–$3.46, easing concern that higher costs or weather-related demand swings could push results below its target range.

On an ongoing basis (non-GAAP), Alliant reported Q1 EPS of $0.82 versus $0.83 a year ago, with management pointing to higher revenue requirements tied to rate-base growth at its regulated utilities and higher allowance for funds used during construction. The quarter also included a $0.05 per-share benefit tied to remeasurement of deferred tax assets that was excluded from ongoing results, while financing, depreciation, and maintenance expenses remained notable offsets.

Beyond the quarter’s numbers, investors appear focused on incremental contracted load from large customers. Alliant highlighted the signing of an approximately 370 MW electric service agreement in Iowa and said total contracted data center demand now stands at about 3.4 GW, reinforcing the market view that future load growth could support regulated investment and earnings visibility.

The next catalyst is management’s May 1, 2026 conference call, where investors will listen for additional detail on the data-center pipeline, capital spending cadence, regulatory assumptions, and how financing costs may evolve as the buildout continues. With guidance reaffirmed, the stock’s follow-through may hinge on whether Alliant can convert contracted demand into in-service infrastructure on schedule while containing operating and maintenance expense.
