Pinnacle West Capital (PNW) is back in focus after third quarter fiscal 2025 results topped analyst expectations, supported by higher transmission revenues, stronger sales, and a higher earnings guidance range for the full year.

The raised guidance arrives alongside firm recent momentum, with a 12.76% year to date share price return and a 15.03% total shareholder return over one year. The 52.41% three year total shareholder return suggests longer term holders have also been rewarded.

If this earnings beat has you looking at utilities differently, it could be a good time to scan 24 power grid technology and infrastructure stocks as a way to find other electricity infrastructure names on your radar.

Yet with Pinnacle West Capital trading above the average analyst price target and internal estimates, you have to ask yourself: is the recent run stretching valuation, or is the market still not fully pricing in future growth?

Most Popular Narrative: 3.6% Overvalued

The most followed narrative pegs Pinnacle West Capital's fair value at $95.92, which sits below the last close of $99.39. This sets up a mild valuation gap you may want to understand.

The ongoing influx of large commercial and industrial customers (notably data centers and manufacturers), along with a backlog of nearly 20 GW in uncommitted customer interconnection requests, signals substantial upside potential for volumetric sales and rate base expansion, positively impacting revenue and long-term earnings.

Curious what kind of revenue trajectory, margin shift, and future earnings multiple are baked into that fair value line? The full narrative spells out the growth math behind this utility style pricing, and how long regulators and capital spending are expected to support it.

Result: Fair Value of $95.92 (OVERVALUED)

However, there are still clear swing factors, with regulatory lag on upcoming rate relief and extreme weather related grid costs both capable of reshaping this growth story.

Another View: Earnings Multiple Sends a Softer Signal

While our fair value model pegs Pinnacle West Capital at $95.92 and labels the shares as 3.6% overvalued, the current P/E of 20x tells a slightly different story. It sits below the US Electric Utilities average of 22.4x and under the 20.8x fair ratio our work suggests the market could lean toward. This points to only modest valuation risk if sentiment or sector flows shift again.
