Pinnacle West Reports 2020 Second-Quarter Results

Pinnacle West Capital Corp. (NYSE: PNW) today reported consolidated net income attributable to common shareholders of $193.6 million, or $1.71 per diluted share of common stock, for the quarter ended June 30, 2020. This result compares with earnings of $144.1 million, or $1.28 per share, in the same 2019 period.

Hotter-than-normal weather was the primary driver in the quarter-over-quarter improvement, increasing revenues, net of fuel and purchased power costs, by $48 million (after-tax), or $0.43 per share. Lower operations and maintenance expenses also contributed to the company's bottom line, partially offsetting impacts of the COVID-19 pandemic.

"Like many electric utilities, weather is a major factor in our business. The dramatic contrast between Arizona's temperatures in second-quarter 2020 compared to the same time last year is reflected in the results we are reporting today," said Pinnacle West Chairman, President and Chief Executive Officer Jeff Guldner. "Excluding the substantial impact of weather on our results, sales were down year-over-year primarily due to declines in retail energy sales and business closures amid the pandemic. During this challenging time for Arizona, our employees continue to innovate and lower costs, and we are making more support and pandemic relief available to our customers and communities."

Temperatures Set New Records

Some of the quarter's daily high temperatures in APS service territory beat or matched previous records not seen in more than a century. According to the National Weather Service, the period's average high temperature was 97.4 degrees ? an increase of 4.5% over 2019's quarter and 2.2% over 10-year historical averages. By comparison, second-quarter 2019 included the mildest month of May Arizona had experienced in 40 years, which was reflected in customers' lower energy use and a significant decrease in operating revenues.

The number of residential cooling degree-days (a utility's measure of the effects of weather) increased 57% versus the year-ago period and were 14.1% higher than historical 10-year averages. In fact, May 2020 had more cooling degree-days than in any May since 2009, while only three years since 1974 have produced more cooling degree-days during the month.

COVID-19, however, continued to have a negative impact on retail sales and revenues. With some businesses still closed or operating at partial capacity, retail energy sales (excluding the impacts of weather) were down 1.3%, or $0.10 per share, compared to last year's second quarter. For the period March 13 to July 28, overall weather-normalized sales were down about 1% year over year.

Operationally, Guldner said APS employees continue to execute well, ensuring reliable customer service amidst extreme summer temperatures and increased customer demand. On July 30, customers set an all-time record peak demand of 7,659 megawatts, eclipsing the previous record of 7,363 MW set in June 2017.

Employees Reduce Costs to Customers' Benefit

In addition to the effects of weather, 2020 second-quarter results positively reflect customer growth of 2.4% and lower O&M expenses. Using Lean principles introduced in 2019, the company continues to focus on employee-led projects and activities to create and capture cost savings.

For example, the Procurement Operations team delivered significant savings by negotiating lower prices with vendors, maximizing the competitive bidding process, and driving efficiency gains within existing vendor contracts. These efforts, along with negotiating early pay discounts with suppliers, have contributed about $5 million in customer affordability savings through the second quarter. Altogether, employees have been challenged to increase efficiency and decrease costs by $20 million this year alone.

New Report Describes Pathways to a Clean, Sustainable Energy Future

Looking to the future, Guldner added that the company is focused on achieving a constructive regulatory outcome in its current rate case, as well as realizing its previously announced Clean Energy Commitment goal of 100% carbon-free electricity by 2050 ­­? while also maintaining affordable prices for a customer base that is among the fastest-growing in the nation.

A report posted to the company's website in June provides more details on pathways to achieving this future, including the 2030 target of achieving a 65% clean energy resource mix and a commitment to end use of coal-fired generation by 2031.

"Our clean energy objectives are both ambitious and achievable," Guldner said. "With a combination of the right technologies, collaborative partnerships and a supportive policy environment, we can and will deliver a carbon-free energy future while maintaining affordability for our customers."

More COVID-19 Support Offered to Customers through Difficult Times

As previously announced, APS acted early to support customers and communities impacted by COVID-19, pledging $8 million in pandemic relief ? one of the largest commitments of any utility in the country. This support includes a robust Customer Support Fund to provide direct assistance to APS customers struggling to pay their bills.

In the second quarter, this fund was increased to help more residential customers with $100 bill credits, and to offer qualifying small businesses with up to $1,000 in bill credits. As of July 29, the Customer Support Fund has provided more than $1.8 million of bill relief to APS customers.

A full list of the company's actions in response to the pandemic is available on the Pinnacle West website, and APS customers are encouraged to visit aps.com/COVID19 for up-to-date details on available resources and support.

Financial Outlook

While the company cannot predict the duration and longer-term impacts of the ongoing COVID-19 pandemic, as of today Pinnacle West continues to believe its 2020 consolidated earnings guidance of $4.75 to $4.95 per diluted share is still achievable.
