8-K: Pinnacle West Reports Lower Q2 Earnings Amid Milder Weather

Pinnacle West Capital Corp. reported lower second-quarter 2025 financial results compared to the prior year, primarily due to milder weather, despite robust customer and sales growth.

Summary

• Consolidated net income attributable to common shareholders for Q2 2025 was $192.6 million, or $1.58 per diluted share, a decrease from $203.8 million, or $1.76 per diluted share, for the same period in 2024.
• Net income for the first two quarters of 2025 was 14.8% lower than the net income in the first half of 2024.
• The decrease in Q2 2025 earnings was primarily due to milder weather (15.4% fewer cooling degree-days), higher operations and maintenance expense, lower pension and other postretirement non-service credits, higher depreciation and amortization expense, increased interest charges, and higher income taxes due to lower tax credits.
• These negative factors were partially offset by higher transmission revenues, increased customer usage and growth, higher Allowance for Funds Used During Construction (AFUDC), and investment gains at subsidiary El Dorado.
• Arizona Public Service Co. (APS) experienced robust customer growth of 2.4% and sales growth of 5.2% in the second quarter of 2025.
• APS customers set an all-time record peak demand of 8,527 megawatts (MW) on July 9, 2025, surpassing the previous record of 8,210 MW set in August 2024.
• The company updated its clean energy goals from an aspirational zero-carbon approach to an aspirational carbon-neutral approach by 2050, removing interim targets to better reflect the near-term need for reliability and affordability.
• Pinnacle West continues to estimate its consolidated earnings for 2025 will be within a range of $4.40 to $4.60 per diluted share on a weather-normalized basis.

Future Outlook

Pinnacle West continues to estimate its consolidated earnings for 2025 will be within a range of $4.40 to $4.60 per diluted share on a weather-normalized basis. The long-term EPS growth target is 5%-7% off the original 2024 midpoint, driven by retail customer growth of 1.5%-2.5% and weather-normalized retail electricity sales growth of 4%-6% (including 3%-5% from large commercial and industrial customers). The company plans $9.66 billion in capital expenditures from 2024-2027 to support reliability and growth, with new APS-owned resources coming online between 2026 and 2028. APS has filed a 2025 rate case application requesting rates to be effective in the second half of 2026, seeking a net revenue increase of $580 million and an allowed return on equity of 10.70%. The clean energy goal has been updated to an aspirational carbon-neutral approach by 2050, removing interim targets to prioritize reliability and affordability.

Management Comments

• "While our second-quarter financial results were within our expectations, they were lower than the same period in 2024 due in large part to cooler weather compared to last year's record-high temperatures, including the hottest June on record."
• "Given how big an impact air conditioning has on energy use here in Arizona, it's no surprise that the cooler weather resulted in lower earnings this quarter."
• "Company employees continue to execute well, ensuring reliable customer service amid the extreme summer temperatures and increased customer demand during the 2025 second quarter."
• "Our mission is to reliably serve customers at the lowest cost possible. To do that, we need to integrate the most reliable and cost-effective resources available to us to meet Arizona's fast-growing energy needs."
• "Clean energy remains an important consideration for us, but always with a focus on a balanced energy mix that best serves reliability and affordability."

Industry Context

Pinnacle West's results reflect the significant impact of weather on energy consumption and utility earnings, a common factor in the industry. The strategic shift in clean energy goals from "zero-carbon" to "carbon-neutral" and the removal of interim targets highlight the industry's ongoing challenge of integrating intermittent renewable resources while ensuring dispatchable capacity, often relying on natural gas, to meet peak demand and maintain grid stability. The company's focus on affordability and reliability amidst rapid growth is a key theme across the U.S. utility landscape.

Key Dates

Recommendation

While the company reported lower quarterly earnings and diluted EPS year-over-year, management stated these results were within expectations, primarily due to milder weather. The underlying business fundamentals remain strong, characterized by robust customer and sales growth in a high-growth service territory, successful management of record peak demand, and a significant capital investment plan to support future reliability and growth. The strategic adjustment to clean energy goals prioritizes reliability and and affordability, which is a pragmatic approach for a utility. However, the upcoming rate case application, proposing a substantial rate increase, introduces regulatory uncertainty and potential customer impact. Given the mixed financial performance (lower YoY but within expectations) and the balance of growth opportunities against regulatory and cost pressures, a "hold" recommendation is appropriate for investors seeking stable, long-term utility exposure, awaiting further clarity on rate case outcomes and the impact of the revised clean energy strategy.
