What the filing says
Arizona Public Service (APS), subsidiary of Pinnacle West Capital Corp ($10.7B market cap), filed 2025 rate case (Docket E-01345A-25-0105) requesting $692M total revenue requirement increase, offset by $83M adjustor transfers, yielding $609M net increase and 14.69% customer bill impact on day one. Request is based on $15.8B test year rate base (12/31/2024), embedded 4.26% cost of debt, requested 10.70% ROE, and proposes Formula Rate Adjustment Mechanism (FRAM) with ±40 bps deadband. Final decision estimated December 2026.
Why this rating
14.69% bill increase is material to customers and rate base trajectory; moderate relative to $10.7B market cap (~5.7% of annual revenues). Regulatory outcome uncertain. Partially offset by strong 5%-7% long-term EPS growth guidance and $10.35B capex plan.
