Pinnacle West Capital Corporation, parent of Arizona Public Service Company (APS), returned to profitability in Q1 2026. Net income attributable to common shareholders was $32.9 million, or $0.27 per diluted share, versus a $4.6 million loss a year earlier, on operating revenues rising to $1.15 billion from $1.03 billion.
Operating income more than doubled, helped by higher retail electric revenues and lower operations and maintenance expense, partially offset by increased fuel, purchased power, and depreciation. APS, the regulated utility segment, generated $51.8 million of net income versus $0.3 million in the prior-year quarter.
The company continued heavy investment, with Q1 2026 capital expenditures of $628 million and construction work in progress of $1.89 billion. APS issued $600 million of 5.10% senior unsecured notes due 2036 and had $316 million of commercial paper outstanding, while Pinnacle West had $103 million of commercial paper.
Regulatory activity remains central. APS’s 2025 rate case seeks a significant base rate increase and proposes a Formula Rate Adjustment Mechanism, while recent ACC decisions affect fuel recovery, transmission rates, demand-side management, and rooftop solar export pricing. The company is also pursuing federal nuclear production tax credits but currently records related amounts as uncertain tax positions.

Operating revenues rose to $1.15 billion from $1.03 billion, helped by hotter‑than‑normal weather, higher transmission revenues, customer growth and lower operations and maintenance costs. Management highlighted record warmth in Arizona that lifted usage, and reaffirmed 2026 earnings guidance of $4.55 to $4.75 per diluted share on a weather‑normalized basis.

The proxy emphasizes strong governance with 10 of 11 directors independent, a refreshed board under a retirement policy, and robust risk oversight across cybersecurity, wildfire, and resource adequacy.
