# Pinnacle West Capital (PNW)

Pinnacle West Capital is the holding company for Arizona Public Service, the largest electric utility in Arizona.

## AI Exposure Score

**27/100, Peripheral.** Phoenix is one of the largest US data center markets, and large-load customers, including the TSMC semiconductor ecosystem and hyperscaler campuses, dominate APS's disclosed growth pipeline. The regulated structure keeps the AI linked slice of earnings modest despite strong load growth.

## What the company does

Pinnacle West Capital is the holding company for Arizona Public Service, the largest electric utility in Arizona. APS generates, transmits and distributes electricity to customers across the state, including the Phoenix metro, and earns returns approved by Arizona regulators on its infrastructure investment.

Phoenix has become one of the country's busiest markets for data centers and advanced manufacturing. The TSMC semiconductor complex and multiple hyperscaler data center campuses sit in or near APS territory, and large-load customers dominate the utility's disclosed growth pipeline. APS also operates the Palo Verde Generating Station, one of the largest nuclear plants in the United States, giving it carbon free firm power that data center operators value.

Founded in 1985 and headquartered in Phoenix, Pinnacle West employs about 6,600 people and trades on the NYSE.

## Role in the AI buildout

Pinnacle West sits in the Utilities & Grid layer of the AI buildout. Phoenix ranks among the top US data center markets, and APS is the utility that connects those campuses, along with the TSMC semiconductor ecosystem growing around them. Its load growth runs among the highest of any US utility, driving new generation, storage and transmission investment. Palo Verde's nuclear output adds firm, carbon free supply. As a regulated utility, though, Pinnacle West earns approved returns on that buildout rather than AI revenue.
