Most Popular Narrative: 2.6% Undervalued

With Pinnacle West Capital's fair value pegged at $94.92 by the most followed narrative and a last close of $92.41, the stock sits a touch below what analysts anticipate. This invites attention to the driving forces behind this target.

“Pinnacle West's accelerated infrastructure investments in transmission, distribution, and generation (including the new regional natural gas pipeline and major grid projects) are expected to significantly expand the regulated rate base, supporting higher allowed returns and future revenue growth. 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.”
