Common Stock Dividend Growth “IDACORP’s Board of Directors has approved an annual dividend increase every year since 2012, resulting in a cumulative average growth rate of over 9%. These changes represent an overall increase of 123 percent in IDACORP’s quarterly dividend over that period. Our customer and earnings growth have allowed us to increase the dividend to shareholders... management [currently] expects to recommend to the Board of Directors future annual increases… of 5 percent or more which would keep the company near the upper end of the current target payout ratio. However, we expect to further discuss with the board the appropriate target payout ratio in mid-November.” Darrel T.
