Quarterly Performance Details

Alliant Energy Corporation reported consolidated unaudited GAAP EPS of \$0.87 for the first quarter of 2026, representing a year-over-year increase. However, ongoing EPS (Non-GAAP) saw a slight dip to \$0.82 from \$0.83 in Q1 2025. The ongoing EPS excludes a \$0.05 per share benefit related to the remeasurement of deferred tax assets, specifically reflecting changes in estimated state income tax apportionment.

The company has reaffirmed its full-year ongoing EPS guidance of \$3.36 – \$3.46 per share, underscoring its commitment to delivering steady growth and maintaining over a decade-long track record of a compound annual earnings growth rate exceeding 6%.

Key drivers for the quarter’s results include higher revenue requirements from increasing rate base at both IPL (\$0.05/share) and WPL (\$0.10/share), investments in generation and energy storage, and increased allowance for funds used during construction. These positives were partially offset by higher financing and depreciation expenses related to capital investments, and other operating and maintenance expenses driven mainly by planned maintenance and the addition of new energy resources.

Retail electric and gas sales declined by an estimated \$0.04 and \$0.03 per share in 2026 and 2025, respectively, largely due to the impact of temperatures on customer demand. The company provides detailed statistics on heating degree days and utility sales, highlighting weather-driven variability in earnings.

Price-Sensitive Items and Shareholder Information

• New Data Center Agreements: The signing of the 370 MW electric service agreement in Iowa (with customer migration from WPL to IPL) is highly significant. The company now has five executed agreements, translating customer demand into structured, long-term growth. This increases total contracted data center demand to approximately 3.4 GW, positioning Alliant Energy as a key utility partner for data center expansion in the Midwest, a sector expected to drive major load growth and future earnings.
• Ongoing EPS Guidance: Reaffirmation of the \$3.36 – \$3.46 range signals management confidence in achieving targets, supporting investor expectations and potentially stabilizing or boosting share price.
• Deferred Tax Asset Adjustment: The \$0.05/share benefit related to state income tax apportioned is excluded from ongoing EPS. This is a non-recurring item and not associated with the core business, but investors should note its impact on GAAP vs. Non-GAAP results.
• Capital Expenditures and Rate Base Growth: Growth in the rate base at IPL and WPL (driving higher revenue requirements) is a fundamental positive. However, higher financing and depreciation expenses associated with capital investments must be watched for margin impact.
• Cash Flow and Balance Sheet: Operating cash flow improved to \$368 million (from \$249 million in Q1 2025). However, cash and cash equivalents decreased substantially to \$115 million (from \$556 million), reflecting significant debt retirements (\$1.075 billion) and new borrowings (\$400 million), alongside capital expenditures.
• Dividend: Quarterly common dividend rate per share increased to \$0.535 (from \$0.50 in Q1 2025), with book value per share rising to \$28.74 from \$27.61, highlighting growing shareholder value.
• Risks and Forward-Looking Statements: Alliant Energy outlines numerous risks that could materially affect results, including regulatory changes, construction delays, supply chain disruptions, weather impacts, cybersecurity risks, and tax policy changes. The forward-looking EPS guidance assumes stable economic conditions, normal weather, successful execution of capital plans, and no major regulatory or legal disruptions.

Segment Performance and Non-GAAP Measures

Segment earnings breakdown for Q1 2026 shows IPL at \$0.36/share, WPL at \$0.45/share, Corporate Services at \$0.02/share, ATC Holdings at \$0.04/share, and Non-utility and Parent at (\$0.05)/share (after adjustment for the state tax apportionment benefit). Total consolidated Non-GAAP EPS is \$0.82/share.

The company provides detailed reconciliations between GAAP and Non-GAAP results, emphasizing the exclusion of items not typically associated with ongoing operations for investor clarity. Management uses these adjusted figures for performance-based compensation and segment analysis.

Any changes in these factors could materially affect Alliant Energy’s financial results and share price. The company warns that its forward-looking statements are based on assumptions that may not prove accurate.

Conclusion

The first quarter 2026 results reflect solid execution and continued growth momentum for Alliant Energy. The major data center service agreement, reaffirmed guidance, and strong rate base growth are positive catalysts that may influence share price. However, shareholders must monitor risks related to regulatory changes, construction, supply chain, and tax policy. The ongoing dividend growth and rising book value per share further underline shareholder value creation.
