Pinnacle West Capital (PNW) has drawn fresh attention after completing a US$499.575 million fixed income offering of 4.650% notes due 2029. This move directly affects its capital structure and funding mix.

The stock is trading at US$98.82 after a 1-day share price gain of 1.37%. However, the 7-day and 30-day share price returns are down 3.90% and 4.56%, suggesting that recent momentum has softened. At the same time, the year-to-date share price return of 12.12% and 1-year total shareholder return of 13.65% sit alongside a 5-year total shareholder return of 41.70%. Together, these figures point to a steadier long run for investors than the latest moves suggest.

With recent returns mixed, solid 3-year and 5-year total shareholder returns, and the stock trading about 6% below the analyst price target, you have to ask: is Pinnacle West Capital undervalued, or is the market already pricing in future growth?

Most Popular Narrative: 6.1% Undervalued

On the most followed narrative, Pinnacle West Capital's fair value of $105.21 sits above the last close at $98.82, framing a modest undervaluation built on detailed growth and regulation assumptions.

Analysts expect earnings to reach $839.9 million (and earnings per share of $6.26) by about June 2029, up from $654.1 million today. The analysts are largely in agreement about this estimate.

Want to see what underpins that earnings jump, margin expansion, and higher future multiple assumptions, and how those feed into a discounted value using a 7.11% rate?

Result: Fair Value of $105.21 (UNDERVALUED)

However, the narrative could easily shift if regulatory lag around 2026 rate decisions tightens margins, or if heavy gas and grid spending proves hard to recover.

Another Angle: Earnings Multiple Sends A Mixed Signal

While the analyst narrative suggests a fair value of $105.21, Pinnacle West Capital currently trades on a P/E of 18.3x versus 21.3x for the US Electric Utilities industry and 21.8x for peers, compared with a fair ratio of 19.7x. That gap hints at some value support, but also raises the question of whether the market is baking in lower growth or higher risk than analysts assume.

Before leaning too heavily on that P/E gap, it is worth checking how it stacks up against the fuller valuation breakdown, including that fair ratio and peer comparison, in See what the numbers say about this price — find out in our valuation breakdown.
