PNW

Pinnacle West is essentially a pure-play regulated Arizona utility through APS, with demand growth as its key strategic asset. APS posted 2.4% customer growth in 2025 and expects 1.5%–2.5% average annual growth through 2030, supporting a durable rate-base growth runway in a state benefiting from in-migration and commercial expansion. The moat is regulatory rather than technological, so execution and Arizona Corporation Commission outcomes drive long-term value.

Financially, results are steady but not accelerating: 2025 net income attributable to common shareholders was $616.5M ($5.05 diluted EPS) versus $608.8M ($5.24) in 2024, with operating revenues of $5.34B in 2025. Management’s 2026 EPS guide of $4.55–$4.75 implies a step-down from 2025, reflecting normalization of weather and higher financing/depreciation costs. At about $104/share (4/17/2026), PNW trades near 28.5x trailing EPS (~$4.89), a demanding multiple for a utility when earnings are guided lower.

The 12-month thesis is that above-average load growth plus an eventual 2026 rate decision can re-anchor earnings growth and reduce regulatory overhang. The biggest catalysts are milestones in APS’s 2025 rate case (rate changes not expected until the second half of 2026) and evidence that sales growth remains in the targeted mid-single digits. Key risks are an unfavorable rate outcome, higher interest rates raising the allowed-return debate, and continued dilution/financing needs as capex ramps.

Recommendation: HOLD. The growth backdrop is real, but the stock’s current valuation leaves limited margin of safety given 2026 EPS is guided below 2025 and the rate-case outcome remains the swing factor.
