Quarterly results buoyed by strong operational performance, warmer weather than a year ago
Employees ensure reliable customer service despite damaging monsoon season
APS among most improved utilities for residential and business customer satisfaction

Pinnacle West Capital Corp. (NYSE:PNW) today reported consolidated net income attributable to common shareholders for the 2022 third quarter of $326.3 million, or $2.88 per diluted share. This result compares with net income of $339.8 million, or $3.00 per share, for the same period a year ago.

Like the first two quarters of 2022, the company's lower third-quarter results reflect the unfavorable outcome of the company's prior rate case, which was implemented on Dec. 1, 2021. As a result of that rate decision, the Company is no longer deferring costs related to the Four Corners selective catalytic reduction (SCR) and Ocotillo modernization projects to a regulatory asset. These costs are now reflected in the income statement and result in a reduction in net income.

Other factors negatively affecting the 2022 third-quarter results were lower revenue driven by the inability to continue using alternative revenue accounting treatment for the lost fixed cost recovery (LFCR) mechanism; higher depreciation and amortization expense due to increased plant assets and updated depreciation rates; and higher operations and maintenance expense. These negative factors were partially offset by warmer weather than a year ago; customer growth of 2.0 percent; increased retail sales of 1.3 percent; and lower income taxes.

"During the quarter, our employees continued to do what they do best: maintain reliable electric service for our 1.3 million customers despite monsoon storms that created damaging winds, heavy rains and flash flooding," said Pinnacle West Chairman, President and Chief Executive Officer Jeff Guldner. "Our workforce safely and quickly restored service to customers after multiple volatile summer storms toppled a combined 811 poles – 255 more poles than the prior three summers combined."

Guldner noted the company's generation fleet also operated well. In particular, Palo Verde Generating Station – the nation's largest energy producer, all carbon-free – recorded a summer capacity factor of 100.2% – its highest figure since tracking began in 2010.

"Our careful long-term planning, resource adequacy, flexibility and innovative programs proved beneficial to our customers throughout the summer," he said, adding that the company also was able to assist neighboring utilities during an early-September heatwave that resulted in 15 energy emergency declarations by others across the West. "Those off-system sales directly benefit APS customers by lowering our overall costs while helping maintain regional grid stability."

APS Commitment to Customer Satisfaction Reflected in Latest J.D. Power Results

Delivering value to Arizona Public Service (APS) customers went beyond just keeping lights on and air-conditioners running through the summer season. J.D. Power's (JDP) 2022 third-quarter residential results also reflected APS's commitment to improving customers' overall experience.

Compared to 2021, APS has made quartile gains in every single driver of residential customer satisfaction. Consequently, overall satisfaction is now well above industry benchmarks when compared to the company's large investor-owned peers. This improvement places the company firmly into the second quartile for residential customer satisfaction. APS's strongest performing drivers through the first three quarters of 2022 were Customer Care (phone and digital), Power Quality and Reliability, Corporate Citizenship, and Billing & Payment. Additionally, JDP's Business 2022 mid-year results place the company in the first quartile nationally for business customers.

"There's no doubt in my mind that creating customer value is inseparably linked to increasing shareholder value," Guldner said. "Our team has embraced this customer-centric focus to achieve an industry-leading customer experience, while demonstrating compassion and advocacy for our customers. As a result, our employees' commitment and focus has led to APS being among the most improved utilities in the nation for both residential and business customer satisfaction."

A Look to the Future

Looking forward, Guldner said, "We are creating long-term value for customers and shareholders by executing our strategy of operational excellence and sound capital investment to meet the energy needs of one of the fastest growing regions in the country. Additionally, disciplined cost management remains a central theme at the company and – along with our recent rate case filing – is a key to future earnings improvement."

Filed last week, the company's general rate case will focus on a return to balanced ratemaking, which will enable the company to make responsible and necessary investments to meet the needs of its customers – today and in the future. These investments include:

Ensuring service reliability and resilience;
Securing a clean, balanced energy supply for Arizona; and
Continuously improving support for all customers, including expanded bill assistance programs for those who need additional support.

Financial Outlook

Given the positive year-to-date impacts of beneficial weather, strong sales and customer growth, the company increased its 2022 consolidated earnings guidance range to $4.20 to $4.35 per diluted share from a previously disclosed range of $3.90 to $4.10 per share.
