01—Abstract

Summary

Summary of the 8-K filed February 20, 2026. Cited figures are marked; the original filing is the authoritative source.

Alliant Energy Corporation reported fourth-quarter and full-year 2025 results in a press release furnished as Exhibit 99.1 to this combined Form 8-K, filed jointly with Interstate Power and Light Company and Wisconsin Power and Light Company.

GAAP diluted EPS was $3.14a for 2025, up from $2.69 in 2024. Ongoing (non-GAAP) EPS was $3.22, compared with $3.04 in 2024, which the company describes as 6% growth. Fourth-quarter GAAP EPS was $0.55 versus $0.58, and fourth-quarter ongoing EPS was $0.60 versus $0.70.

Ongoing 2025 results exclude a $0.05b per share asset valuation charge for the non-utility business and a $0.03 per share charge from remeasuring deferred tax assets for higher estimated state income tax apportionment. The company cited higher revenue requirements from rate base growth, partly offset by higher other operation and maintenance expenses and higher depreciation and financing costs. The company affirmed its 2026 ongoing EPS guidance of $3.36 to $3.46 and reiterated a track record of compound annual earnings growth of more than 6%.

Management said it renegotiated an electric service agreement with QTS based on a new project location. The release also updated projected capital expenditures for 2026 through 2029 to $3,130 millionc, $3,580 million, $3,625 million and $3,065 million, respectively, with renewables and energy storage, gas projects and electric distribution systems among the main categories. For 2025, the filing reports total revenues of $4,362 million (versus $3,981 million), net income attributable to common shareowners of $810 million (versus $690 million), and net cash flows from operating activities of $1,169 million.

Long-term debt, net, rose to $10,954 milliond from $8,677 million at year-end 2024. The quarterly common dividend rate was increased to $0.5075 per share from $0.48.

Net income attributable to common shareowners was $810 million versus $690 million. Higher revenue requirements from authorized rate base increases were the primary driver, partly offset by higher other operation and maintenance expenses and higher depreciation and financing expenses.

    Fourth-quarter GAAP EPS was $0.55 versus $0.58, and ongoing EPS was $0.60 versus $0.70. The filing's fourth-quarter earnings tables show IPL ongoing EPS of $0.32 versus $0.39 and WPL ongoing EPS of $0.31 versus $0.34, with the press release not attributing the decline to a single cause.

    Ongoing EPS for 2025 excludes a $0.05 per share asset valuation charge for the non-utility business and a $0.03 per share charge related to remeasuring deferred tax assets, reflecting an increase in estimated state income tax apportionment driven by higher projected electric revenues from commercial and industrial customers, including data center agreements.
