Alliant Energy’s latest earnings call struck an upbeat tone, with management emphasizing a decade of steady earnings growth, solid capital execution and a powerful new leg of demand from data centers. While higher costs, equity needs and Wisconsin regulatory noise remain overhangs, the company framed these as manageable execution risks rather than structural threats to its growth story.
Consistent Earnings Growth
Alliant highlighted a ten‑year compound annual EPS growth rate of 6.3%, underscoring its track record of consistent expansion. Ongoing 2025 EPS is up $0.18 year over year, supported by more favorable weather and disciplined cost recovery, and management projects 7%‑plus annual earnings growth for 2027 through 2029.
Shareholder Returns and Dividend Discipline
Investors have been rewarded with total shareowner return above 13% over the past year, reflecting both price performance and dividends. The company marked its twenty‑second consecutive annual dividend increase, signaling confidence in cash flow durability and a commitment to returning capital to shareholders.
Data Center Deals Powering Demand
Data centers are emerging as a transformational growth driver, with four signed electric service agreements totaling 3 gigawatts of peak load, which the company equates to about 50% future demand growth. After relocating the QTS project from Wisconsin to Iowa, management also sees another 2 to 4 gigawatts of potential upside from additional data center opportunities.
Capital Plan and Regulatory Execution
Alliant’s consolidated four‑year capital program of about $13.4 billion for 2026 through 2029 remains intact, even after reallocations tied to the QTS move. On the regulatory front, the utility secured a unanimous settlement for Wisconsin’s 2026–2027 rate review and obtained Iowa approvals for a 720‑megawatt gas plant and a 94‑megawatt RICE unit.
Operational Milestones and Resource Readiness
The company advanced its transition plan with 275 megawatts of energy storage now in service and turbine upgrades at Neenah and Sheboygan Falls completed. It also locked in gas turbine reservations and project sites for self‑developed gas resources while safeguarding renewable and storage projects to preserve key tax credits.
Financing Position and Capital Structure
For 2026, Alliant expects to issue up to $1.2 billion of long‑term debt across the parent and its utilities, after retiring a $300 million term loan. Of roughly $2.4 billion of planned common equity through 2029, about $1.0 billion has already been raised via forward equity tools, leaving about $1.3 billion to place over the next several years.
Customer Affordability and Stable Rates
Management stressed its pledge to keep Iowa retail electric base rates flat for existing customers through the end of the decade, even as investment rises. The strategy leans heavily on investment tax credits from energy storage assets, helping the company earn its allowed return while shielding customers from frequent rate hikes.
Rising Operating and Development Costs
Higher operating and maintenance spending tied to planned generation work and new assets is pressuring the cost base, alongside elevated development expenses for new generation. These factors, plus rising depreciation and financing costs from the expanding capital program, partially offset the earnings lift from a growing rate base.
Non‑Recurring Items Weighing on EPS
Alliant flagged two modest one‑time charges that were excluded from ongoing earnings but still affected reported results. A $0.05 per share hit came from suspending a Travero wind turbine blade recycling effort, while a $0.03 per share charge stemmed from remeasuring deferred tax assets.
Wisconsin Regulatory and Local Headwinds
Community concerns around data center development, including annexation and rezoning issues, contributed to the QTS decision to relocate from Wisconsin to Iowa. At the same time, five active regulatory dockets in Wisconsin, covering projects like LNG storage and wind additions, inject uncertainty into the pace and shape of the state’s build‑out.
Equity Needs and Refinancing Risk
The remaining $1.3 billion of equity to be raised by 2029 poses some dilution risk, particularly if market conditions turn volatile. Upcoming parent‑level debt maturities around March 2026 must also be refinanced, and management is assuming conservative, potentially higher interest rates in its plan, which could temper near‑term EPS leverage.
Timing Risk on Data Center Load Ramp
Most of the incremental data center demand is expected to materialize from 2027 onward, leaving 2026 retail sales growth guidance at roughly 1%. The relocation of the QTS project introduced less than a one‑year delay to the expected load ramp, underscoring the timing risk around when contracted demand actually hits the system.
EPS Pressure Versus Rate Base Growth
While management described rate base growth around the low‑double‑digit range, the combination of equity issuance and cautious refinancing assumptions may restrain near‑term EPS upside. That dynamic could leave Alliant trailing some peers that are translating similar rate base expansion into faster earnings growth.
Impact of Pending Regulatory Decisions
Key cases still on regulators’ desks could shift project economics and timelines, including Iowa’s advanced rate‑making decision on up to 1 gigawatt of wind and Wisconsin rulings on LNG storage and about 430 megawatts of wind. Delays or adverse outcomes might affect tax credit capture and customer pricing, adding another layer of execution risk.
Guidance and Outlook
Alliant reaffirmed its 2026 earnings and dividend guidance and reiterated an ambitious target of at least 7% compound annual earnings growth from 2027 to 2029. The outlook leans on roughly 1% retail sales growth in 2026, a $13.4 billion capex plan, expanded storage‑driven tax credits, and a balanced mix of debt and equity funding, supported by recent regulatory approvals.
Alliant’s earnings call painted a picture of a utility leaning into data center‑driven growth while carefully managing capital, regulation and customer bills. For investors, the story blends dependable dividend growth and a maturing demand super‑cycle with familiar utility risks around costs, regulation and financing, leaving execution as the key watch point over the next few years.
