PINNACLE WEST REPORTS 2022 FIRST-QUARTER RESULTS

•Lower quarterly results in line with company’s expectations following “financial reset” from recent rate case decision

•Robust sales and customer growth underscore Arizona’s economic strength

•APS employees focus on summer preparedness and reliability using advanced robotic technology

PHOENIX – Pinnacle West Capital Corp. (NYSE: PNW) today reported consolidated net income attributable to common shareholders of $17.0 million, or $0.15 per diluted share of common stock, for the quarter ended March 31, 2022. This result compares with $35.6 million, or $0.32 per diluted share, for the same period in 2021.

The lower first-quarter results reflect the adverse outcome of the company’s recent general rate case. Implemented on Dec. 1, 2021, the unfavorable rate case decision was the primary driver for the lower quarter-over-quarter results. The largest contributing factor was discontinuation of the Four Corners and Ocotillo cost deferrals. Other major factors negatively affecting the 2022 first-quarter results were higher depreciation and amortization expense due to increased plant assets and higher income taxes. These negative effects were partially offset by higher customer usage and customer growth, increased transmission revenue and lower operations and maintenance expense.

“Despite the impact the rate decision had on our first-quarter revenue, 2022 has started off in line with our expectations during what we’ve previously expressed as a ‘financial reset year,’ ” said Pinnacle West Chairman, President and Chief Executive Officer Jeff Guldner. “Our employees contributed to strong operational performance, and we continue to serve one of the fastest-growing service territories in the nation. Our quarterly customer growth was a robust 2.2%, and we experienced stronger-than-projected sales growth of 4.4%.”

“Though this growth is positive, it still does not make up for the negative impacts of the rate case outcome,” Guldner stated. “In fact, the tremendous growth we are experiencing accentuates the need for substantial capital investment in order to maintain the reliability and safety of our system, and it emphasizes the need for reasonable and timely recovery of those investments.”

Employees prepare for summer reliability
Guldner said as more families and companies choose Arizona to live and do business, “our employees are laser-focused on the critical preparations necessary to continue delivering

reliable power throughout our peak summer season – especially as energy supplies tighten in the western region.”

In addition to building new infrastructure to meet growth, maintaining new infrastructure to ensure reliability, and procuring additional energy to meet summer demand, APS employees are nearing completion of a scheduled maintenance and refueling outage at Palo Verde Generation Station Unit 1. As the largest source of carbon-free energy in the U.S., the three-unit nuclear plant is critical to meeting summer demand across the desert southwest.

APS employees also are conducting fire-mitigation line patrols and emergency operations drills; managing supply-chain constraints to acquire critical spare equipment; and performing preventative maintenance – all part of the company’s longstanding seasonal preparation activities.

Advanced technology keeps employees safe while ensuring customer reliability
As part of its proactive system upkeep, the company’s Predictive Maintenance (PDM) inspection team uses advanced technology to conduct safe and efficient facility assessments. With infrared cameras, three active drones and two robots, the company can perform safer inspections of hard-to-reach and dangerous areas such as transmission towers, power lines and manholes.

The latest addition to the PDM team is a Boston Dynamics-built robot named Spot the Dog. APS employees can remotely operate Spot to examine confined spaces, conduct night inspections and perform security work using a built-in infrared camera – all without an employee having to step foot in an unsafe or restricted area.

“APS has always been dedicated to technology and innovation, and Spot the Dog is just the next evolution in our reliability journey,” said Guldner. “This robot and other high-tech tools help our employees stay safe, while also improving efficiency and system reliability for our customers.”

The company’s focus on technology also is allowing it to deliver a superior customer experience. Enhancements to the APS website, interactive outage map, and alerts by text and email have enhanced customers’ digital experience, grown transaction engagement and improved overall customer satisfaction.

Financial Outlook
For 2022, the company continues to expect its consolidated earnings guidance will be in the range of $3.90 to $4.10 per diluted share on a weather-normalized basis. Key factors and assumptions underlying the 2022 outlook can be found in the first-quarter 2022 earnings presentation slides at pinnaclewest.com/investors.
