PHOENIX--(BUSINESS WIRE)--Pinnacle West plans to release its 2026 first-quarter financial results before U.S. financial markets open on Monday, May 4, 2026.

Pinnacle West, through its subsidiary Arizona Public Service, operates the Palo Verde nuclear plant. The Palo Verde nuclear plant is the country's most productive power plant.

Pinnacle West Capital gains from customer growth, data center demand and an $8B infrastructure push, but faces nuclear outage and commodity-price risks.

Pinnacle West (PNW) reported earnings 30 days ago. What's next for the stock?

Pinnacle West's stock has re-rated to 21.9x forward earnings during a guided-down year, leaving little margin for error ahead of a politically charged rate case decision expected in Q4 2026. Avista disclosed a significant data center deposit on its Q4 call that could reshape the growth story for a utility trading below its historical valuation multiples. PNW's demand story in Arizona is real (5% sales growth, TSMC expanding), but the gap between spending and earning won't close until the rate case resolves.
