10-Q: Alliant Energy Reports Increased Earnings for Q1 2025, Driven by Customer Investments and Temperature Impacts

Alliant Energy Corporation reports a net income of $213 million for the first quarter of 2025, up from $158 million in the same period last year, driven by customer investments and temperature impacts.

Summary

• Alliant Energy Corporation's net income attributable to common shareowners for Q1 2025 was $213 million, or $0.83 per diluted share, compared to $158 million, or $0.62 per diluted share, for Q1 2024.
• The increase in net income was primarily due to higher revenue requirements from Interstate Power and Light Company (IPL) and Wisconsin Power and Light Company (WPL) capital investments, estimated temperature impacts on retail electric and gas sales, and the timing of income tax expense.
• These increases were partially offset by higher depreciation and financing expenses.
• Alliant Energy plans to develop or acquire new generation investments, including approximately 1,500 MW of new natural gas resources, approximately 1,200 MW of new wind generation, approximately 800 MW of new energy storage, refurbishments at approximately 500 MW of existing wind farms, improvements of approximately 280 MW at existing natural gas-fired EGUs, and the conversion of existing coal-fired EGUs to natural gas.
• IPL and WPL have filed for or received regulatory approvals for various generation and energy storage projects.
• WPL filed a retail electric and gas rate review with the Public Service Commission of Wisconsin (PSCW) for the 2026/2027 forward-looking Test Period, requesting increases in annual rates for retail electric and gas customers.
• WPL has entered into an electric service agreement with a new customer expected to build a data center in Beaver Dam, Wisconsin.
• IPL and WPL have filed requests for approval of individual customer rates associated with certain data centers expected to be constructed in their service territories.
• The EPA announced it expects to initiate a formal reconsideration of various environmental regulations and programs.
• Alliant Energy expects to issue up to $1.3 billion of common stock and IPL and WPL expect to issue long-term debt in 2025.
• In March 2025, AEF entered into a $300 million variable rate (5% as of March 31, 2025) term loan credit agreement (with Alliant Energy as guarantor), which expires in March 2026.
