Pinnacle West Capital : REPORTS LOWER 2022 SECOND-QUARTER RESULTS - Form 8-K

PINNACLE WEST REPORTS LOWER 2022 SECOND-QUARTER RESULTS

•Quarterly results consistent with expectations; full-year 2022 earnings guidance maintained

•Customer and sales growth continue to bolster the company's underlying fundamentals

•EPA recognizes APS as 2022 ENERGY STAR® Partner of the Year

PHOENIX - Pinnacle West Capital Corp. (NYSE: PNW) today reported consolidated net income attributable to common shareholders of $164.3 million, or $1.45 per diluted share of common stock, for the quarter ended June 30, 2022. This result compares with earnings of $215.7 million, or $1.91 per share, in the same 2021 period.

As with the 2022 first quarter, the company's second-quarter results reflect the unfavorable outcome of the company's recent general 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 second-quarter results were higher depreciation and amortization expense due to increased plant assets and updated depreciation rates; lower revenue driven by the inability to continue using alternative revenue accounting treatment for the lost fixed cost recovery (LFCR) mechanism; and higher operations and maintenance expense. These negative factors were partially offset by customer growth and lower income taxes.

"Second-quarter results were in line with our expectations, and we remain well-positioned to meet our financial commitments for the full year," said Pinnacle West Chairman, President and Chief Executive Officer Jeff Guldner, citing strong year-over-year second-quarter sales growth of 3.2%, robust customer growth of 2%, superior reliability and operating performance by employees, and continued cost management.

EPA Recognizes Company's Energy Efficiency and Demand Response Programs

For the second consecutive year, the Environmental Protection Agency (EPA) recognized Arizona Public Service with the ENERGY STAR Partner of the Year Award for excellence in customer energy efficiency programs. These offerings include the APS Marketplace, a one-stop online shop that offers customers smart energy products at competitive prices, and the company's Cool Rewards program. In the last year alone, these and other APS energy efficiency programs have helped the company manage energy demand and reduce lifetime carbon dioxide emissions by 2.3 billion pounds - the equivalent of removing 224,791 gasoline-powered passenger vehicles from Arizona roadways.

"In its fourth year of operation, our Cool Rewards demand response program essentially operates as a virtual power plant where our customers provide nearly 100 megawatts of flexible, clean capacity," said Guldner. "The program connects nearly 66,000 APS customers with smart thermostat technology that helps them save money, while also playing an integral role in conserving energy when the demand on the electric grid is at its highest. This partnership helps us ensure reliable, uninterrupted service to our customers on the hottest Arizona days, while also assisting us on our journey to 100% clean and carbon-free electricity by 2050."

APS Helping Customers Manage Their Energy Use, Bills, Heat

In addition to its award-winning energy efficiency programs, APS provides a variety of resources and money-saving tips to help customers stay comfortable and manage their electric bills through summer's scorching temperatures.

The APS mobile app and aps.com let customers check their energy use, access energy-saving tips customized to their service plan, and monitor and report outages.

Additionally, in the face of extreme temperatures and prolonged heat, APS has expanded its heat-relief initiatives, including partnering with local community organizations to aid the state's most vulnerable populations. This includes support for The Salvation Army's network of 18 cooling and hydration stations across Arizona; a collaboration with the Foundation for Senior Living offering emergency repair or replacement of AC systems during the scorching summer months; and an emergency shelter and eviction-protection program in partnership with St. Vincent de Paul.

The company also offers a variety of assistance programs for those who are struggling with their bill. These offerings include the Energy Support programs, which provide limited-income customers with a monthly discount on their bill; Crisis Bill Assistance, providing up to $800 annually to qualified limited-income customers who experience unexpected financial hardship; and Project SHARE, a Salvation Army-administered service providing up to $300 annually in emergency energy bill assistance.

APS customers needing aid are encouraged to visit aps.com/support for a full list of assistance programs, including up-to-date details on year-round financial resources and support.

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.
