• Grid Expansion: Continued investment in grid infrastructure to support growth, particularly for large customers like TSMC, which is expanding its operations in Arizona.
• Nuclear Operations: Palo Verde, the largest nuclear plant in the U.S., operated at 100% capacity and received an excellence award for safety and performance.

• Capital Investment: The capital program remains focused on reliability and resilience, with a rate base growth target of 7% to 9% through 2028.

4. Challenges and Points of Concern

• Weather Impact: The decline in earnings year-over-year was largely attributed to milder weather conditions in 2025 compared to the previous year.
• Cost Pressures: Higher financing costs, pension, and OPEB expenses are ongoing challenges that could impact profitability.
• Regulatory Lag: The company faces regulatory lag that may affect its ability to recover costs and maintain credit metrics, particularly as it navigates the upcoming rate case.
• Uncommitted Load: While there is significant uncommitted load potential (20 gigawatts), translating this into committed contracts remains a challenge.

5. Notable Q&A Insights

• Integrated Resource Plan (IRP): An updated 15-year IRP will be filed midyear, detailing load forecasts and resource plans, but will not include uncommitted demand.
• Formula Rate Implications: The recent UNS case was viewed as constructive, but differences exist between the situations of UNS and APS, particularly regarding growth and risk profiles.
• Customer Commitments: The majority of committed load is from high load factor customers, including TSMC, but expansions beyond current commitments are still under negotiation.
• FFO to Debt Metrics: The company is focused on maintaining a strong FFO to debt ratio, currently in the high 14% range, with aspirations to keep it within the 14% to 16% target range.
• Nuclear Future: While there is interest in new nuclear opportunities, any developments are expected to be medium to long-term rather than immediate.
