What Pinnacle West Capital does
Pinnacle West Capital is a Phoenix-based holding company whose subsidiary provides retail and wholesale electric service in Arizona. It runs the full electricity chain: generating power from a mixed fleet of nuclear, gas, oil, coal and solar plants, carrying it over overhead and underground transmission lines, and delivering it through substations and distribution networks, along with energy storage assets. As a regulated electric utility incorporated in 1985, its earnings depend mainly on the rates regulators allow it to charge and on the size of the asset base it invests in. That makes it a typical steady, infrastructure-heavy utility tied to Arizona's electricity demand.

What is Pinnacle West Capital worth?
On an owner-earnings DCF, Pinnacle West Capital's most-likely value is about $7 versus a recent price near $99 (92% above fair value). But TacticScale only calls a stock undervalued when the price sits below its conservative no-growth floor (~$4) with a margin of safety — so the honest verdict here is “Stretched — richly priced.” Fair value earns its keep only at the extremes, not in the wide middle.
Today's $99 is above even the optimistic Bull case ($9) — the market expects faster, longer growth than modeled here. Expensive unless that extra growth actually shows up.
⚠ High leverage — net debt is 392.4× annual cash flow. Net debt is subtracted from this fair value, but refinancing at higher rates, principal timing, and share dilution aren’t modeled — the equity can be worth far less if cash flow weakens.
⚠ Capital-intensive — this business reinvests heavily, so free cash flow runs well below its earnings. Fair value here is built on free cash flow, which understates owner earnings for reinvestment-heavy companies — read it as conservative.
Analysis, not advice. Fair value is a margin-of-safety estimate from a deterministic owner-earnings DCF, not a price target or recommendation. See the full breakdown →
