Alliant Energy Announces Second Quarter 2026 Results

About this update from Alliant Energy Corporation

MADISON, Wis., July 30, 2026 --( BUSINESS WIRE )--Alliant Energy Corporation (NASDAQ: LNT) today announced U.S. generally accepted accounting principles (GAAP) consolidated unaudited earnings per share (EPS) of $0.65 for second quarter 2026, compared to $0.68 for the second quarter of 2025. Alliant Energy reaffirmed its consolidated ongoing EPS guidance for 2026 of $3.36 - $3.46, and indicated earnings are currently trending in the upper half of the range. "We delivered another solid quarter of operating and financial performance and our full-year forecasted results are currently trending in the upper half of our full-year ongoing earnings guidance range," said Lisa Barton, Alliant Energy President and CEO. "With three data centers making significant construction progress, and meaningful progress on energy resource investments, we are positioning to accelerate earnings growth and enable significant economic development in the communities we serve; all while maintaining customer protections and reliability." In the second quarter of 2026, the primary drivers of Alliant Energy's results were higher revenue requirements from increasing rate base at Interstate Power and Light Company (IPL) and Wisconsin Power and Light Company (WPL) of $0.09 and $0.09 per share, respectively, including investments in generation and energy storage, higher equity earnings from corporate venture investments, and higher temperature-normalized retail electric and gas sales. These items were offset by higher other operating and maintenance expense primarily related to labor and increased electric distribution and generation costs from planned maintenance activities and the addition of new energy resources, higher financing and depreciation expenses, estimated temperature impacts on retail electric and gas sales, and timing of income tax expense. Retail electric and gas sales decreased an estimated $0.03 and increased an estimated $0.02 per share in the second quarter of 2026 and 2025, respectively, due to impacts of temperatures on customer demand. Alliant Energy's Non-GAAP, or ongoing, EPS for six months ended June 30, 2026 excludes $0.05 per share benefit related to the remeasurement of deferred tax assets, reflecting a remeasurement of estimated state income tax apportionment. This non-GAAP adjustment is presented to supplement GAAP results and highlight financial measures not typically associated with ongoing operations. 2026 Earnings Guidance Alliant Energy is reaffirming its consolidated ongoing EPS guidance for 2026 of $3.36 - $3.46 per diluted share. Assumptions for Alliant Energy's 2026 EPS guidance include, but are not limited to: The 2026 earnings guidance does not include the impacts of any material non-recurring valuation adjustments, regulatory-related charges or credits, reorganizations or restructurings, future changes in laws, regulations or regulatory policies, adjustments made to deferred tax assets and liabilities from changes in forecasted state income tax apportionment and valuation allowances including further corporate tax rate changes in Iowa, changes in credit loss liabilities related to guarantees, pending lawsuits and disputes, settlement charges related to pension and other postretirement benefits plans, federal and state income tax audits and other Internal Revenue Service proceedings, impacts from changes to the authorized return on equity for American Transmission Company LLC (ATC), or changes in GAAP and tax methods of accounting that may impact the reported results of Alliant Energy.
