Performance was driven by strong customer growth of 2.2% and weather-normalized sales growth of 7.4%, fueled by the rapid expansion of Arizona’s semiconductor and advanced manufacturing sectors.
Management attributed significant quarterly earnings benefits to higher transmission revenue and record-breaking heat in March, which offset increased financing costs and depreciation.
The company is utilizing machine learning and automation to enhance grid resilience and optimize asset maintenance, specifically targeting wildfire and weather risk mitigation.
Strategic positioning is centered on supporting TSMC’s multi-fab expansion and a growing supply chain, with 4.5 gigawatts of large-load demand already committed.
Operational excellence is being maintained through high reliability and top-tier customer satisfaction rankings, with APS earning the highest national awareness score for customer programs.
The company is executing a transition in its generation mix, including the Red Hawk natural gas expansion and evaluating bids for new resources to enter service between 2029 and 2031.

Annual sales growth guidance is maintained at 4% to 6% for 2026, with long-term projections of 5% to 7% through 2030 based on committed industrial ramp-ups.
The upcoming Integrated Resource Plan (IRP) filing will provide a 10-to-15-year framework for generation and transmission needs, incorporating organic growth and committed high-load factors.
Management aims to narrow the regulatory lag to within 50 basis points of the authorized ROE by 2029 through constructive rate case outcomes and formula rate designs.
The ‘subscription model’ for large-load customers is expected to result in filed agreements this year, shifting some of the 20-gigawatt uncommitted queue into the committed category.
Capital allocation strategy prioritizes de-risking the equity plan, with $850 million in priced equity already secured to meet needs through 2028.

O&M expenses decreased significantly due to lower planned outage costs and a Commission-mandated reduction in energy efficiency programs.
The retirement of the Cholla coal plant impacted depreciation, while management is currently studying the site for potential conversion to natural gas generation.
Transmission revenue contributed 16 cents per share this quarter, reflecting a step-function increase in recovery from heightened infrastructure investments.
Management explicitly stated they will not put the utility balance sheet at risk for new nuclear projects unless large customers provide financing support.
