Most Popular Narrative: 0% Overvalued

The analyst consensus Narrative on Simply Wall St puts Pinnacle West Capital’s fair value at $104.97, almost identical to the recent $105.26 share price. This frames the latest 2026 guidance upgrade against expectations that are already built into the stock.

The multi year capital program of about US$7.95b for 2026 to 2028, including higher transmission spend and new gas capacity such as the Redhawk expansion, Agave, Ironwood, Sundance and the planned Cholla gas conversion, is set to increase the regulated asset base and future revenue.

Growing transmission investment, including the potential multi hundred mile Four Corners to Cholla line that could approach US$1b and is recovered through a FERC formula rate with annual true ups, creates an additional earnings stream that can support both revenue and net margins over time.
