| About Idacorp Inc |
| IDACORP, Inc. is a holding company. Co. operates through its subsidiary, Idaho Power Co. (Idaho Power). Idaho Power is an electric utility engaged in the generation, transmission, distribution, sale, and purchase of electric energy and capacity and is regulated by the state regulatory commissions of Idaho and Oregon and by the Federal Energy Regulatory Commission (FERC). Idaho Power provides electric utility service to over 633,000 retail customers in southern Idaho and eastern Oregon. Its customers are in food processing, electronics and general manufacturing, agriculture and other sectors. We show 49 historical shares outstanding datapoints in our IDA shares outstanding history coverage, used to compute IDA market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing IDA market cap history over the course of time is important for investors interested in comparing IDA's market cap history versus its peers. Many "beginner" or "novice" investors will look at one stock trading at a price of $10 per share and another trading at a price of $20 per share and think the latter company is worth twice as much. Of course, that is a completely meaningless comparison without also knowing how many shares outstanding there are for each of the two companies, and then calculating their respective market caps. Comparing the share price of IDA versus a peer is one thing; comparing IDA market cap versus a peer is a completely different story. Furthermore, via fluctuation both in per-share price and in the number of shares outstanding (via issuance of new shares over time, the repurchase of existing shares), the market cap for a company like IDA can fluctuate over the course of history. With this page we aim to empower investors researching IDA by allowing them to research the IDA market cap history. |
