Why is Pinnacle West Capital Corporation (PNW) stock moving?
Pinnacle West reported Q3 2026 results on Nov 3 and raised its FY2026 adjusted EPS guidance to $5.05-$5.25 from $4.55-$4.75, above the $4.81 estimate, while reaffirming its 5%-7% long-term EPS growth target and raising its long-term sales growth outlook to 8%-10% through 2030. Operating momentum was supported by weather-normalised Q3 retail sales up 9.5% and commercial and industrial sales up 14.5%, and committed large load rose to 5.8 GW with over 84% not yet served. BMO Capital raised its price target from $104 to $108 on Nov 4. The share price spiked to an intraday high of 108.34 and closed at 107.74 on Nov 3 on 2.36M shares, but gave back those gains on heavier volume of 3.02M shares on Nov 4, fell to a low of 101.66 on Nov 6, and recovered to close at 105.96 on Nov 10 on 1.27M shares, close to its late-October range. Pending catalysts include the expected filing of a 25-year, 1.88 GW power deal with Taiwan Semiconductor Manufacturing Company in the coming days, ongoing negotiations within a 20-GW extra-large-customer queue, and a general rate case decision expected in December 2026. The Nov 6 8-K covers routine investor meetings and adds little new information.

About Pinnacle West Capital Corporation
Pinnacle West Capital is the holding company for Arizona Public Service (APS), Arizona's largest electric utility, which serves about 1.4 million customers across most of the state, including the fast-growing Phoenix area. It is the operator and largest co-owner of the Palo Verde nuclear plant, one of the biggest nuclear plants in the US by power output, and it is adding a lot of new customer demand from data centers and chip factories such as TSMC.
How it makes money
Nearly all of its revenue comes from APS selling electricity to homes, businesses and industrial customers at rates set by the Arizona Corporation Commission, plus some transmission revenue regulated by federal authorities (FERC). Residential customers make up the largest share of sales. Earnings grow mainly as the utility invests in power plants, the grid and batteries and is allowed to earn a set return on those investments through rate cases. Revenue is roughly $5–6 billion a year (approximate), and the company pays a quarterly dividend, currently $0.91 a share.
