Ameren (AEE) is back in focus after affirming its 2026 earnings guidance and outlining a long term EPS growth outlook supported by multi year infrastructure spending and projected rate base expansion.

The recent guidance confirmation and earnings update appear to have kept momentum building, with Ameren’s share price returning 8.75% over the past month and a year-to-date share price return of 10.32%, while five-year total shareholder return sits at 79.17%.

If this steady utility story has your attention, it could be a good moment to broaden your watchlist with 24 power grid technology and infrastructure stocks that may benefit from long-term grid and infrastructure spending themes.

With Ameren trading close to recent analyst targets and its own 2026 EPS range now on the table, a key question is whether you are looking at an underappreciated utility or a stock where future growth is already fully priced in.

Most Popular Narrative: 3.6% Undervalued

Ameren’s latest close of $111.27 sits below the most followed fair value estimate of $115.38. The narrative points to a small valuation gap built on long term earnings and rate base assumptions.

Ongoing and future investments in grid modernization, resilience (e.g., smart substations, composite poles, automation), and clean energy resources (wind, solar, batteries) are expected to expand Ameren's regulated rate base at a forecasted 9.2% CAGR, enabling higher allowed returns and improved net margins.

Curious what sits behind that rate base and margin story? The core of this narrative is a long runway of planned spending and an earnings profile that leans on steady growth assumptions rather than rapid acceleration. Want to see which revenue and profit projections have to land for that to hold up? The full narrative lays out the numbers and the timing.

Result: Fair Value of $115.38 (UNDERVALUED)

However, this hinges on data center demand and large capital plans staying on track. Any regulatory setbacks or tax credit changes could quickly challenge that growth story.

Another Take: DCF Flags a Richer Price

While the narrative fair value sits at $115.38 and suggests Ameren is 3.6% undervalued, our DCF model tells a different story. On that approach, the current $111.27 share price sits above a future cash flow value of $93.03, which points to an overvalued result instead.
