Is Pinnacle West Capital (PNW) Below Fair Value After Its Latest Earnings Miss?
Why Pinnacle West Capital’s latest earnings matter now
Pinnacle West Capital (PNW) recently reported second quarter 2026 earnings that came in below estimates and below the prior year, while reaffirming full year guidance and highlighting substantial ongoing capital investment plans.
The softer 30 day and 90 day share price returns, which are down 3.92% and 5.38% respectively, suggest some momentum has cooled recently. However, the year to date share price return of 10.64% and 5 year total shareholder return of 62.81% still indicate a solid longer term record for Pinnacle West Capital around the current US$97.52 level.

Most Popular Narrative: 7.2% Undervalued
Pinnacle West Capital’s most followed narrative pegs fair value at about $105.07, which is above the recent $97.52 close, so the story backs a modest valuation gap.
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. The company's progress on regulatory modernization, including proposals for formula rate mechanisms and rate design adjustments to ensure large customers pay their full share, should improve cost recovery, reduce regulatory lag, and stabilize net margins as future capital investments come online.

Result: Fair Value of $105.07 (UNDERVALUED)
