Company profile

Pinnacle West Capital Corp. is an energy holding company based in Phoenix with consolidated assets of about $32.6 billion. The company maintains approximately 6,200 megawatts of generating capacity and employs around 6,600 people across Arizona and New Mexico.

Through its principal subsidiary, Arizona Public Service, Pinnacle West provides retail electricity service to approximately 1.5 million Arizona homes and businesses.

Pinnacle West Capital Corp. reported consolidated net income attributable to common shareholders of $178.6 million, or $1.43 per diluted share, for the quarter ended June 30, 2026, missing the analyst consensus estimate of $1.47 per share by 2.72%. This compares to $192.6 million, or $1.58 per diluted share, in the same period of 2025, representing a 9.49% year-over-year decline in earnings per share. On the revenue front, the company reported quarterly sales of $1.455 billion, beating the analyst consensus estimate of $1.390 billion by 4.68%, and marking a 7.06% increase over sales of $1.359 billion in the same period last year. The results reflect a decline in net income primarily due to higher interest charges, increased depreciation and amortization, and lower transmission service revenues, partially offset by favorable weather effects, robust customer growth, decreased operations and maintenance expenses, and lower taxes.

Chairman, President and Chief Executive Officer Ted Geisler attributed the sustained load growth to an early summer onset, with temperatures reaching 105° F in March. This early heat drove a 7% increase in residential cooling degree days compared to the prior year, leading customers to use air conditioners sooner and more heavily. Arizona Public Service Co. (APS), Pinnacle West's principal subsidiary, delivered reliable service during extreme demand while achieving robust residential customer growth of 2.1%.

Financial Performance

The following table summarizes key financial metrics for the quarter:

Operating figures in thousands, except per share amounts.

Operational Highlights

APS demonstrated strong operational resilience during the peak summer season. Weather-normalized sales grew by 5.6%, while total sales increased by 9.6%. Overall customer growth stood at 2.1%. Geisler noted that these usage patterns contributed to financial results within company expectations, emphasizing that the early heatwave supported energy demand even as temperatures later normalized to levels similar to the previous year.

Customer Support Initiatives

As Arizona enters its peak summer season, APS has expanded customer support resources to help manage higher seasonal energy bills. Enhancements include expanded Care Center resources, targeted communications, and community outreach. The company also updated its Safety Net program to provide earlier notifications about past-due bills and potential disconnections. Additionally, APS offers financial assistance programs, including discounts of up to 25% or 60% for eligible vulnerable customers, emergency utility bill assistance of up to $1,000 annually, and the APS CARE program, which provides up to $500 in emergency aid administered by the Salvation Army.

Infrastructure and Outlook

Looking ahead, APS announced plans to convert two retired coal-fired units at the Cholla Power Plant near Joseph City to natural gas. This project aims to bring approximately 380 MW of dispatchable energy online by 2029, sufficient to power about 61,000 Arizona homes. Construction is expected to begin in 2028, subject to regulatory approvals. For the full year 2026, Pinnacle West estimates consolidated earnings will range between $4.55 and $4.75 per diluted share on a weather-normalized basis.
