The company reported that the increase in net income for the quarter was driven by higher net income at Idaho Power. Key factors contributing to this growth included an overall increase in Idaho base rates, effective January 1, 2026, due to the outcome of the 2025 Settlement Stipulation for Idaho Power's general rate case. Additionally, the company noted that customer growth contributed to the results, with the number of Idaho Power customers growing by approximately 15,000, or 2.2 percent, during the twelve months ended September 30, 2026.
On October 29, 2026, IDACORP announced it is increasing its full-year 2026 earnings guidance to a range of $6.40 to $6.50 per diluted share.

The company also provided updated metrics for Idaho Power, including operating and maintenance expense guidance of $535 million to $545 million and capital expenditures, excluding AFUDC, of $1,300 million to $1,500 million.
