| Feb 20, 2026 | business | Alliant Energy operates as a regulated investor-owned public utility holding company, primarily providing electric and natural gas services in the Midwest through its two public utility subsidiaries. IPL serves approximately 505,000 electric and 230,000 natural gas retail customers in select Iowa markets, while WPL provides electric and natural gas service to about 505,000 electric and 205,000 retail customers in Wisconsin. Both subsidiaries also conduct wholesale electricity sales.
Beyond its core utility operations, Alliant Energy's non-utility holdings, organized under AEF, include a 16% ownership interest in ATC, an independent transmission-only company, a 50% cash equity stake in a 225 MW non-utility wind farm in Oklahoma, and Travero, a supply chain solutions company offering rail, barge, and truck freight services.
The company is extensively regulated by FERC, the Iowa Utilities Board (IUC), and the Public Service Commission of Wisconsin (PSCW), which oversee retail rates, service standards, and facility investments. A significant trend is the planned evolution of its electric supply mix towards new renewable generation, energy storage facilities, and natural gas resources, reducing reliance on coal. Environmental regulatory uncertainty, particularly concerning EPA rules on greenhouse gas emissions (e.g., CAA Section 111(d) and 111(b)) and coal combustion residuals, poses a material risk, though compliance costs are generally recoverable through rates. While retail electric customers lack supplier choice, competition arises from self-generation and third-party renewables. Natural gas operations benefit from regulatory cost-recovery mechanisms, mitigating the impact of price volatility on operating income. |

| Feb 20, 2026 | mda | Alliant Energy reported consolidated net income of $810 million ($3.14 EPS) in 2025, up from $690 million ($2.69 EPS) in 2024. This increase was primarily driven by higher revenue requirements from capital investments and favorable temperature impacts, benefiting from the absence of 2024's Lansing Generating Station asset valuation charge and restructuring costs. Retail electric sales volumes grew 2%, and gas sales volumes increased 14% in 2025.
The company plans substantial capital expenditures totaling $13.3 billion from 2026-2029. This investment focuses on adding approximately 1,600 MW of new natural gas, 1,000 MW of energy storage, and 1,300 MW of new renewable generation (wind/solar) to address evolving load growth, including an anticipated 3 GW from new data center customers in Iowa and Wisconsin. Alliant Energy actively utilizes Inflation Reduction Act tax credits, transferring $285 million in 2025.
Regulatory approvals include IPL's $185 million retail electric base rate increase effective October 2024, coupled with a moratorium through September 2029, and a $10 million gas rate increase. WPL secured electric and gas rate increases for 2026 and 2027. The company targets a 5% dividend increase for 2026 and expects higher future earnings from an expanding rate base, though O&M, depreciation, and interest expenses are also projected to rise. Alliant removed interim 2030 environmental goals, prioritizing reliability and customer energy needs, while maintaining its 2040 coal exit and 2050 net-zero GHG targets. Liquidity remains strong with $556 million cash and $1.2 billion available credit, supporting investment-grade credit ratings. |

| Feb 20, 2026 | risk_factors | Alliant Energy faces significant operational and financial risks centered on its aggressive capital expenditure plan, which totals approximately $13 billion over the next four years. A primary concern is the reliance on large load growth customers, particularly data centers. These projects require substantial upfront investment in generation and transmission infrastructure, creating risks related to construction delays, supply chain disruptions, and potential demand volatility if these customers alter their energy needs or self-supply power.
Regulatory risk remains a critical factor, as the company’s ability to recover costs and earn authorized returns depends on timely approvals from the IUC, PSCW, and FERC. Specific constraints, such as IPL’s retail electric rate base moratorium through 2029 and evolving MISO capacity accreditation requirements, limit financial flexibility. Furthermore, the company is vulnerable to environmental and climate-related mandates, including potential GHG regulations that could render existing fossil-fuel assets uneconomical.
Financial stability is also tied to tax policy, specifically the utilization of renewable tax credits and the potential impact of the OBBB Act on credit transferability. Finally, the company faces persistent headwinds from inflation, rising interest rates, and a competitive labor market, all of which threaten to increase costs that may not be fully recoverable through regulated rates. |
