• Earnings Guidance: Pinnacle West raised its full-year 2026 consolidated earnings guidance range upward to $5.05 to $5.25 per diluted share, reflecting strong sales, customer additions, and summer weather impacts through the first nine months.

Key Operational Drivers

1. Sales and Customer Expansion:
   • Overall weather-normalized sales increased 9.5%, supported by a 14.5% surge in commercial and industrial sales and 4.5% residential growth.
   • Total customer count grew 1.8% year-over-year (residential up 1.9%).
2. Peak Demand Milestones:
   • APS reached an all-time peak demand record of 9,166 MW on August 2, 2026.
   • Demand exceeded 9,000 MW three separate times during the quarter and surpassed the prior-year peak of 8,648 MW twelve times.
3. Cost Offsets:
   • Gains were partially tempered by increased depreciation and amortization ($242.5 million vs. $224.6 million in Q3 2025) and higher interest expenses.
4. Customer Affordability Programs:
   • APS is rolling out over $33 million in bill credits via the Environmental Benefits Surcharge (~$14 credit for typical residential customers in November), supported by Green Power Partners program revenues, alongside $5 million in shareholder-funded hardship relief.

Strategic & Long-Term Outlook

APS recently submitted its Integrated Resource Plan to the Arizona Corporation Commission, planning for electricity demand that is projected to more than double by 2041, with peak demand forecasted to climb over 5,000 MW above current levels. Management reiterated its Pledge for Responsible Energy Growth, committing to a principle of having extra-large energy consumers (e.g., data centers and large industrial manufacturing facilities) directly fund required grid infrastructure expansions to insulate existing retail customers from cost-shifting.
