Pinnacle West Capital (PNW) has scheduled a Special Call on 10 August 2026, drawing investor attention to potential updates regarding its Arizona-focused regulated electricity business and recent share performance.

The Special Call comes as Pinnacle West Capital’s share price has eased in recent weeks, with a 1-day share price return of a 2.03% decline and a 30-day share price return of an 8.41% decline, while longer term total shareholder returns of 10.71% over 1 year and 56.74% over 5 years indicate that momentum has built over time.

Pinnacle West Capital now trades below the average analyst price target, while the model-based estimate sits above the current share price. Is the recent pullback a warning sign or an opportunity to enter at a lower valuation?

Most Popular Narrative: 7.3% Undervalued

The most followed narrative currently places Pinnacle West Capital's fair value at $105.07, above the last close of $97.36, which frames the recent pullback in a different light.

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.

Investments in grid modernization and resiliency (such as advanced infrastructure for wildfire mitigation, automation, and predictive maintenance) position Pinnacle West to capitalize on increasing electrification and decarbonization efforts, supporting both operational efficiency and margin stability. Read the complete narrative.

Want to understand why this narrative still sees upside for Pinnacle West Capital even after the recent share price weakness? The entire valuation rests on a specific blend of revenue growth, margin improvement, and future earnings multiples that differ from the broader utilities sector. Curious which assumptions carry the most weight in that fair value.

Result: Fair Value of $105.07 (UNDERVALUED)

However, Pinnacle West Capital’s reliance on fossil fuel generation and the risk of regulatory lag around 2026 rate decisions could quickly weaken this undervaluation narrative.

Another View: SWS DCF Model Flags Overvaluation
