Alliant Energy Corporation Q3 2026 Earnings Recap

Alliant Energy’s shares rose 1.4%, a relatively muted reaction to results and an expanded growth outlook. The company raised its expected investment growth rate to 13% and projected earnings growth of 8% or more from 2027 through 2030, while the plan depends on executing large-load projects and associated infrastructure investment.

Key Takeaways

• The refreshed capital investment plan through 2030 is 19% higher than last year’s plan, spanning natural gas generation, renewables, energy storage and grid investments.
• Alliant expects greater than 60% contracted demand growth by 2031, supported by five data centers; three are under construction. Google’s Cedar Rapids expansion has met the company’s planning threshold.
• The company said it is raising the bar for including projects in its outlook, adding local permitting to its criteria alongside visibility into land, transmission and generation.
• Mesabi Metallics’ initial capacity needs are included in the refreshed plan, but a significant portion of its anticipated load is curtailable; future phases would require additional resources.
• Alliant extended Iowa’s electric base rate stability plan through 2030 and said the DOE-backed financing program could deliver up to $1.2 billion in cumulative customer savings over the loans’ 30-year life.
