IDACORP, Inc. (NYSE:IDA) announced today that its Board of Directors approved an increase in the regular quarterly cash dividend on IDACORP’s common stock to $0.90 per share. At the new rate, the indicated dividend is $3.60 per share on an annual basis. IDACORP’s Board of Directors has approved a dividend increase every year since 2011, resulting in a cumulative dividend increase of 200% and compound annual dividend growth rate of 7.6% since 2011.

"We expect our capital expenditures will remain elevated for the foreseeable future, reflective of infrastructure development to meet continuing customer and load growth. We are focused on reinvesting in that growth," said Lisa Grow, IDACORP’s President and Chief Executive Officer. "We continue to expect our dividend growth rate and our earnings per share growth rate to be decoupled, with a target payout ratio between 50% and 60% of IDACORP earnings."

The declaration of dividend payments and the approval of management’s recommendations are at the discretion of IDACORP’s Board of Directors. In determining future dividend actions, the Board of Directors will consider factors such as projected capital requirements, the company’s liquidity position and overall financial condition, the competitiveness of the dividend yield, economic conditions, equity dilution, impacts to credit ratings, and other factors. The dividend declaration, ex-dividend, record, and payable dates will be announced during the fourth quarter of 2026.
