Alliant Energy stock gains as earnings beat estimates

Alliant Energy stock (ISIN US0188021085) opened at USD 64.97 on Nasdaq on September 22, 2026, while the latest quarterly figures show EPS of USD 0.65 and revenue of USD 971 million. The market valuation and earnings update give investors two separate reference points: the share price remains below the average analyst target, while quarterly profit exceeded consensus.

Quarterly earnings beat estimates

According to MarketBeat on September 22, 2026, Alliant Energy reported USD 0.65 earnings per share for its latest quarter, compared with a consensus estimate of USD 0.58. That represents a USD 0.07 earnings beat, while revenue reached USD 971 million against an estimate of USD 896.94 million.

The same report identifies the latest release date as July 30, 2026 and says quarterly revenue was 1.0 percent higher than in the comparable period a year earlier. EPS nevertheless declined from USD 0.68 in the prior-year quarter to USD 0.65, so the revenue increase did not translate into year-over-year earnings growth.

Analysts see a higher valuation

According to MarketBeat on September 22, 2026, 14 research firms held a consensus rating of Moderate Buy, with nine buy ratings and five hold ratings. The average 12-month price target was USD 77.00, above the September 22 opening price of USD 64.97.

Management set fiscal 2026 EPS guidance at USD 3.36 to USD 3.46, while analysts expected full-year EPS of USD 3.43, according to MarketBeat. The guidance range places the midpoint at USD 3.41, which is USD 0.02 below the cited consensus estimate of USD 3.43.

Stock remains below yearly high

The previous completed Nasdaq close was USD 50.32 on September 21, 2026, up 0.8 percent from the prior close, according to the dated market quotation. The session ranged from USD 49.80 to USD 50.60, with approximately 1.1 million shares traded.

The same quotation placed the September 21 close about 6 percent below the 52-week high near USD 53.50 and roughly 12 percent above the 52-week low around USD 45.00. The price range and the September 22 opening quote are different market snapshots, so they are not combined into one closing-price comparison.
