10-Q: Pinnacle West Capital Corp. Q1 2026 Earnings Beat Expectations

Pinnacle West Capital Corporation reported a significant turnaround in its first quarter 2026 results, driven by higher transmission revenues and lower operating expenses, leading to a net income attributable to common shareholders of $33 million, a substantial improvement from a net loss in the prior year.

Summary

• Pinnacle West Capital Corporation (Pinnacle West) reported a net income attributable to common shareholders of $33 million for the three months ended March 31, 2026, a significant improvement from a net loss of $5 million in the same period of 2025.
• This turnaround was primarily driven by a $118 million increase in operating revenues, largely due to higher transmission revenues and increased retail revenues from customer growth and usage patterns, partially offset by higher fuel and purchased power costs.
