Analyst target puts Alliant Energy stock below fair value

Analysts currently assign Alliant Energy a consensus price target of USD 77.00 per share, which represents an upside of about 13.3 percent from a reference level of USD 67.97 cited in a recent comparison of regulated utility peers on September 18, 2026, according to MarketBeat.

In that overview, Alliant Energy is described with a market capitalization of approximately USD 17.62 billion and annual revenue of about USD 4.36 billion, underscoring that the company remains a mid-cap regulated utility with a sizeable, but not dominant, footprint versus larger peers such as Exelon and Xcel Energy on the same date.

Recent earnings and revenue trajectory support the valuation

For fundamentals, a recent comparative analysis of Alliant Energy against a data and infrastructure real estate investment vehicle highlights that the utility generated revenue of USD 4.36 billion in fiscal year 2025 and expanded its net margin to 18.56 percent, making it one of the more consistently profitable regulated utilities in the sector, as of data referenced on September 18, 2026, according to Pluang.

The same analysis states that Alliant Energy reported earnings per share of USD 0.65 in Q2 2026, which came in above market expectations and continues a pattern of gradual earnings growth for the company’s regulated utility business, according to Pluang.

That Q2 2026 earnings figure is part of a broader guidance picture in which consensus estimates for earnings per share in 2026 and 2027 point to year-over-year increases of 6.52 percent and 7.25 percent respectively, suggesting that Alliant Energy is expected to deliver mid-single-digit to high-single-digit earnings growth over the next two years, as summarized on September 18, 2026, by Yahoo Finance.

Valuation, technical signals and investor takeaways

In terms of valuation, Alliant Energy is trading at a premium to the utility industry average, with a forward 12-month price-to-earnings ratio of 18.53 times compared with an industry average of 14.48 times, as of the assessment published on September 18, 2026, according to Yahoo Finance.

Technical indicators, however, have turned more cautious in recent weeks: one comparative technical screen notes that Alliant Energy is showing 17 sell signals versus only 4 buy signals despite its solid fundamentals and earnings beat in Q2 2026, pointing to short-term selling pressure even as long-term earnings visibility remains relatively intact, according to Pluang.

Segment performance has also weighed on sentiment: over the past six months, Alliant Energy’s share price has declined by 7.6 percent, compared with a 10.7 percent drop for the broader utility industry index, indicating that while the stock has underperformed its own mid-2025 highs, it has held up somewhat better than the sector as a whole during the recent period of rising interest rates, as highlighted on September 18, 2026, by Yahoo Finance.
