PINNACLE WEST REPORTS LOWER 2023 SECOND-QUARTER FINANCIAL RESULTS
•Mild weather and higher operating costs impact earnings
•APS supports customers through the summer season
•Company seeks flexible energy resources to serve Arizona's growing energy needs
PHOENIX – Pinnacle West Capital Corp. (NYSE: PNW) today reported a consolidated net income attributable to common shareholders of $106.7 million, or $0.94 per diluted share of common stock, for the quarter ended June 30, 2023. This result compares with consolidated net income of $164.3 million, or $1.45 per diluted share, for the same period in 2022.
Weather was a major driver in the lower second-quarter results, with the Phoenix region experiencing the mildest June since 2009. Other factors included higher operations and maintenance expenses (including increases in non-nuclear generation operating costs and higher transmission, distribution and customer service costs), higher interest charges and lower pension and other postretirement non-service credits. These were partially offset by higher transmission revenue and higher revenue from the Lost Fixed Cost Recovery (LFCR) mechanism.
“We saw cooler-than-usual temperatures in the second quarter compared to a warmer-than average second quarter in 2022. This June was especially mild. Given how big an impact air conditioning has on energy use in the low desert, it’s no surprise that our financial results are lower this quarter,” said Pinnacle West Chairman, President and Chief Executive Officer Jeff Guldner, citing National Weather Service Phoenix data showing that the average June 2023 temperature was almost five degrees cooler than June 2022.
“While the heat was slow to get started, it certainly showed up in time for the Fourth of July, and the Phoenix area set a new record for consecutive days above 110 degrees in July. On July 20, the company hit a new all-time peak of 8,193 megawatts,” said Guldner. “Thanks to our employees’ impressive planning and operating performance, customers continued to receive the reliable service they count on. This performance – combined with robust customer growth and a resolution to the 2019 rate case appeal in June – puts us in a strong position entering the second half of the year.”
Summer is Our Season
June 21 may have been the first official day of summer, but employees at Arizona Public Service Co. (APS), the company’s regulated utility and principal subsidiary, work hard year-round to prepare for the season’s heat, wildfire risks and potential storms.

As temperatures rise, the company helps customers get ready too. Practical tips and energy-saving strategies can aid in managing monthly electricity bills, from installing a smart thermostat through the Cool Rewards demand response program to using the rate plan comparison tool to ensure customers are on the right plan for their energy use. APS also works with communities at higher fire risk to raise awareness about defensible space and having an emergency plan in place.
The company joins forces with local nonprofits to provide heat relief to vulnerable individuals throughout Arizona. In partnership with St. Vincent de Paul, APS helps shelter families through emergency community housing and eviction prevention assistance and supports The Salvation Army’s cooling and hydration stations in nine Arizona counties, among other initiatives.
Ensuring adequate energy supply is another important part of our summer readiness, and several projects came online recently, including 141 megawatts (MW) of battery energy storage at AZ Sun solar sites, 150 MW at the Agave Solar Plant and 238 MW of wind energy through a power purchase agreement.
Seeking Flexible, Innovative Energy Resources for the Future
APS not only is focused on serving customers this summer; the company is taking steps to secure energy supply for years to come. In June, APS issued an all-source request for proposal (RFP) seeking project proposals for flexible and innovative resources to serve growing energy needs as more people and businesses continue to move to Arizona.
The 2023 all-source RFP seeks approximately 1,000 MW to serve customers with even more around-the-clock energy – enough to power about 150,000 Arizona homes. This solicitation is designed to procure a balanced and diverse portfolio that advances clean energy while maintaining reliability and affordability for customers.
“We are seeking the best combination of technologies to serve our customers and deliver value,” said Guldner. “Our resource planning team welcomes a variety of proposals and technologies to support a diverse and affordable energy mix for Arizona. That could include new solar plants and battery energy storage, natural gas resources that can transition to clean hydrogen fuel in the future, and other resources that can ramp up quickly to serve customers during triple-digit summer afternoons.”
This RFP is focused on projects to serve customers beginning between 2026-2028. To learn more about the 2023 all-source RFP, deadlines and instructions to apply, visit aps.com/rfp.
Financial Outlook
Given the positive impact of the 2019 rate case appeal resolution in June and extremely hot weather to start the third quarter – partially offset by higher than previously forecasted operations and maintenance expenses and more moderate weather-normalized sales growth – the company increased its 2023 consolidated earnings range to $4.10 to $4.30 per diluted share on a weather-normalized basis from a previously disclosed range of $3.95 to $4.15 per diluted share. Key factors and assumptions underlying the 2023 outlook can be found in the second quarter 2023 earnings presentation slides at pinnaclewest.com/investors.
