As of June 30, 2026, APS had a 51% common equity ratio, approximately $9.0 billion of shareholder equity, and approximately $17.8 billion of total capitalization; the restriction would apply if equity fell below approximately $7.1 billion assuming capitalization remained constant. On July 31, 2026, APS applied to the ACC to increase its long-term debt limit from $9.5 billion to $12 billion, and the company cannot predict the outcome.
