8-K: Pinnacle West Reports Lower Q2 Income, Cites Higher Costs

Pinnacle West Capital Corp. reported lower second-quarter net income compared to the prior year, primarily due to increased interest charges and depreciation, though results were in line with expectations.

Summary

• Pinnacle West Capital Corp. reported consolidated net income of $178.6 million, or $1.43 per diluted share, for the quarter ended June 30, 2026.
• This represents a decrease from $192.6 million, or $1.58 per diluted share, in the same period of 2025.
• The decline was mainly attributed to higher interest charges, increased depreciation and amortization, and lower transmission service revenues.
• These factors were partially offset by favorable impacts from weather, customer growth and usage, decreased operations and maintenance expenses, and lower taxes.
• The company maintained its full-year 2026 earnings outlook of $4.55 to $4.75 per diluted share on a weather-normalized basis.

Management Comments

• "Summer arrived early this year, with temperatures reaching 105 F back in March. As a result, our customers turned on their air conditioners sooner than usual and continued using them heavily even after temperatures returned to levels similar to last year," said Ted Geisler, Chairman, President and Chief Executive Officer.
• "This usage drove higher energy demand and sustained load growth and contributed to financial results within our expectations."
• "Operationally, Arizona Public Service Co. (APS) employees delivered strong performance throughout the second quarter, maintaining reliable service during extreme summer heat and increased energy demand."
• "When residents shared concerns about how a planned outage could affect their community, our employees took the time to listen and respond. By providing personalized outreach, answering questions, verifying customer information, sharing preparedness resources and connecting residents with APS assistance programs, we were able to better support customers and strengthen trust within the community."
• "Supporting customers extends beyond assistance programs and outage preparedness. APS also is investing in the infrastructure and resources needed to provide the reliable energy service customers count on at the lowest cost possible."

Industry Context

StockSavvy.ai notes that the results reflect typical seasonal demand patterns for utilities in hot climates, exacerbated by early heatwaves. The company's focus on customer growth, energy demand, and infrastructure investment aligns with broader industry trends of modernizing grids and meeting increasing load from economic development, including data centers.

Comparison to Industry Standards

• The reported residential customer growth of 2.1% is robust and likely exceeds the national average for utilities, which often experiences slower growth.
• The 5.6% weather-normalized retail electricity sales growth is strong, particularly for a mature utility market, and is driven by significant C&I customer ramp-ups, including data centers, which is a key growth driver across the utility sector.
• The company's capital expenditure plan of $10.35 billion for 2026-2028, with significant investments in generation, transmission, and distribution, is substantial and indicative of a utility actively managing growth and infrastructure needs, comparable to other large, growing utilities in Sun Belt states.

Stakeholder Impact

• Shareholders: The decrease in net income and EPS may be a concern, but the reaffirmed earnings outlook and strong operational performance provide some reassurance.
• Customers: APS is enhancing customer support and financial assistance programs for peak summer season, including expanded Safety Net program and various discount/assistance programs.
• Employees: The report highlights strong performance by APS employees in maintaining reliable service and going above and beyond to support vulnerable customers.
• Creditors: The company's focus on maintaining investment-grade ratings and a balanced capital structure aims to ensure access to capital markets and manage debt costs.

Next Steps

• The company continues to estimate its consolidated earnings for 2026 to be within a range of $4.55 to $4.75 per diluted share on a weather-normalized basis.
• The conversion of two retired coal-fired units at the Cholla Power Plant to natural gas is planned, bringing about 380 MW of energy online by 2029, subject to regulatory approvals.
• Construction for the Cholla Power Plant conversion is expected to begin in 2028.
• The 2025 APS Rate Case is progressing with testimony summaries and proposed rate design modifications.
• The company plans to file its 2026 Integrated Resource Plan (IRP) by October 30, 2026.

Key Dates

Recommendation

The company met its own expectations despite a year-over-year decline in net income, driven by higher costs. Strong customer growth and energy demand, coupled with a reaffirmed full-year outlook, suggest stability. However, the increased interest expenses and ongoing capital investments warrant a cautious 'hold' stance until the impact of rate recovery and future investments becomes clearer.
