Alliant Energy lifts 2026-2030 capex 19% to $15.9B and raises its 2027 dividend target after a Q3 beat

The utility narrowed its 2026 profit guidance to $3.41-$3.46 a share and extended Iowa's electric rate freeze through 2030, as it raised its dividend target.

Alliant Energy is spending more to serve data centers and still promising shareholders a bigger payout. The utility lifted its 2026-2030 capital expenditure forecast by 19% to $15.9bn and raised its 2027 dividend target to $2.25 a share, from $2.14, after third-quarter earnings of $1.52 a share beat expectations by $0.20. Revenue of $1.28bn edged past the $1.27bn forecast.

The earnings beat is the smaller news. Alliant narrowed its 2026 ongoing earnings guidance to $3.41-$3.46 a share from $3.36-$3.46, which raises the floor and leaves the top unchanged. A higher capital plan paired with a higher dividend target is a statement of confidence in how the extra spending will be paid for.

Part of the answer lies in the federal loan guarantees agreed at subsidiary level a few weeks ago. They cover part of the expanded spending at fixed spreads over Treasurys through 2056, which limits the exposure to rising borrowing costs on that portion. The rest of the $15.9bn still has to be financed, and that is where a reader should look as the plan unfolds.

There is also a political price to manage. Alliant is extending the retail electric base rate stability plan at Interstate Power and Light by a year, through 2030. Chief executive Lisa Barton said the aim is to give Iowa customers predictability. With data-center demand driving the build-out, households will want proof that a bigger spending plan does not end up on their bills, and the freeze on base rates is the company's answer.
