Pinnacle West Capital Corp. Reports Strong Q1 2026 Results, Driven by Record Arizona Heat and Customer Growth

Key Financial Highlights

• Q1 2026 Net Income: Pinnacle West Capital Corp. (NYSE: PNW) reported consolidated net income attributable to common shareholders of \$32.9 million, or \$0.27 per diluted share, for the quarter ended March 31, 2026. This is a significant turnaround from a net loss of \$4.6 million, or a loss of \$0.04 per diluted share, for the same quarter in 2025.
• Operating Revenues: Revenues rose to \$1.15 billion in Q1 2026, up from \$1.03 billion in Q1 2025.
• Customer Growth: The company saw 2.2% customer growth, reflecting continued strength in the Arizona economy and ongoing population influx.
• Weather-Driven Demand: Exceptionally hot weather drove a 9.4% increase in weather-normalized sales growth and higher overall customer energy consumption.
• 2026 Earnings Guidance: Pinnacle West reaffirmed its full-year 2026 consolidated earnings guidance of \$4.55 to \$4.75 per diluted share (weather-normalized).

Operational and Strategic Developments

• Weather Impact: Arizona experienced its warmest winter on record, with average daytime highs and overnight lows in Q1 2026 up 8.6% and 11.9% respectively over the prior year. February was the hottest ever for Arizona, and March broke longstanding heat records with temperatures averaging 12.1 degrees above normal. Phoenix recorded its earliest 100-degree day ever on March 18, the first of nine 100-degree days in the month. This led to increased air conditioning use much earlier than usual, boosting electricity demand.
• APS Summer Preparedness: With robust customer growth and surging energy use, APS (Arizona Public Service, Pinnacle West’s main subsidiary) is focused on summer preparedness, including enhancements to wildfire mitigation, emergency-operations drills, securing critical spare equipment, and preventative maintenance across its infrastructure.
• Infrastructure and Reliability Investments: The company is adding new infrastructure to support growth and reliability, including securing extra energy resources for the upcoming summer. A scheduled maintenance and refueling outage for Unit 2 at Palo Verde Generating Station is concluding, ensuring reliable clean energy supply during peak demand.

Financial Details and Factors Affecting Results

• Revenue Drivers: The \$38 million improvement in results was primarily due to higher transmission revenues, lower operations and maintenance expenses, favorable weather, customer growth, increased usage, and related pricing.
• Offsetting Factors: These gains were partially offset by higher interest expenses, increased income taxes, and higher depreciation and amortization.
• Operating Expenses (Q1 2026 vs Q1 2025):
  • Fuel and purchased power: \$436.7 million (vs. \$380.1 million)
  • Operations and maintenance: \$276.7 million (vs. \$280.1 million)
  • Depreciation and amortization: \$239.9 million (vs. \$234.9 million)
• Interest Expense: Interest charges increased to \$125.8 million (from \$104.9 million).
• Net Income Attributable to Noncontrolling Interests: \$2.19 million (vs. \$4.31 million)

Risks and Forward-Looking Statements

Pinnacle West emphasized several risks that may affect future performance, many of which are potentially price sensitive:

• The company’s ability to achieve timely and adequate rate recovery through regulated rates and mechanisms.
• Potential impacts of regulatory, environmental, and tax changes at federal, state, and local levels.
• Operational risks and significant capital expenditure requirements associated with Palo Verde Generating Station.
• The effects of climate change, especially weather extremes, droughts, and temperature variations on the electric system.
• Risks relating to wildfires, cybersecurity, catastrophic events, and potential shortfalls in insurance coverage.
• Financial market disruptions, rising interest rates, and capital access issues.
• Competition due to deregulation, large customers pursuing self-generation, and technological advancements.
• Challenges related to fuel and water supply, and forecasting load growth—particularly from high-load users such as data centers supporting AI.
• Policy changes via ballot initiatives or referenda in Arizona or other states.
• General economic conditions, including inflation, tariffs, and supply chain constraints.

The company stated it does not undertake to update forward-looking statements except as required by law.

Shareholder-Relevant Takeaways

• Strong Q1 performance and confirmation of full-year guidance are positive signals likely to support share value.
• Significant weather-driven demand growth could boost near-term revenues but also highlights exposure to climate volatility.
• Ongoing investments in infrastructure and reliability signal long-term commitment to growth and service quality, which may support investor confidence.
• Rising operating and interest expenses are important considerations for future profitability.
• Regulatory, environmental, and economic risks remain material and could affect future results.

Conclusion

Pinnacle West Capital Corp.’s Q1 2026 results mark a robust rebound from the prior year’s loss, powered by extreme weather, customer growth, and operational discipline. The company’s reaffirmed guidance and ongoing strategic investments position it well for the remainder of 2026, but investors should closely monitor regulatory, climate, and economic risks that could impact future performance or share value.
