Pinnacle West stock's P/E stood at 19.85 on October 16, 2026, compared with 18.24 for Duke Energy. That valuation gap gives investors a concrete way to compare the Arizona utility with a larger regulated-power peer.

Zacks Investment Research reported on October 9, 2026 that Pinnacle West maintained 2026 earnings guidance of USD 4.55-4.75 per share. The same report said the company expects retail customer growth of 1.50-2.50 percent in 2026 and weather-normalized retail electricity sales growth of 4.00-6.00 percent.

Earnings outlook stays measurable

The guidance range matters because demand growth is being paired with major infrastructure spending. Zacks said Pinnacle West aims to invest USD 7.95 billion through 2028 in generation, transmission and distribution infrastructure. That spending creates a clear test for future earnings: customer growth must translate into higher sales while financing and depreciation costs remain manageable.

Price sits below the yearly high

The market capitalization was USD 12.5 billion. The P/E of 19.85 was higher than Duke Energy's 18.24 but lower than Southern Company's 22.02, putting Pinnacle West between the two peers on this measure.
