Executive summary
Pinnacle West Capital is the holding company for Arizona Public Service, a regulated electric utility that serves homes, businesses and industrial customers across much of Arizona. The utility generates power from natural gas, nuclear, solar and other sources, and it operates the transmission and distribution lines that deliver it. Its rates are set by the Arizona Corporation Commission and federal regulators.
Revenue comes from regulated charges paid by customers for electricity, which depend on rates approved by regulators and on usage. The last twelve months produced $5.6 billion, and revenue has grown at 7.3% a year across the last three years. The operating margin is 20.5%, and the business earns a profit of 4% on the capital invested in it. It carries net debt of 7.7 times EBITDA. The company pays a dividend with a yield of 3.5%.
StocksXray gives Pinnacle West Capital Corp an X-Ray Score of 44 out of 100 (medium confidence), ahead of 29% of the S&P 500 stocks in its sector. Its strongest lens is growth (61) and its weakest is financial health (32).
Our fair value blend is $102.37 (range $102.37 to $102.37). At $103.42 the stock trades 1% above that blend, so the label is "Fair" with medium model uncertainty. Fair value is a range, not a price target.

Every number comes from SEC filings, end-of-day prices and the StocksXray models described on the methodology page. The X-Ray Score ranks each metric against the company's own sector. Fair value blends three models and carries a typical error of about 40%, so treat it as a range. Analyst ratings, price targets and earnings-call summaries are not part of this report. Educational research, not financial advice; read the disclaimer.
