Here are the 424B prospectus supplements from IDACORP, Inc. (IDA) in our archive over the last 12 months, newest first, and each one links through to the document itself with the summary and the scores our analysis gives it.
A 424B covers the supplement that carries the terms of a priced offering, so if you follow IDA and want that one kind of document rather than the whole filing history, this is the page to keep. The company's other filings, of every form, are on the full IDA filings page.
IDACORP, Inc. is offering up to $600,000,000 of its common stock through an at-the-market equity distribution agreement with multiple sales agents and related forward counterparties entered into on May 15, 2026. The company may sell shares directly through the sales agents or ask forward counterparties to sell borrowed shares to hedge forward sale agreements. Proceeds received by the company will depend on whether and when forward sale agreements are physically settled; the company expects to elect full physical settlement but may elect cash or net share settlement, which could change cash proceeds or require delivery of shares or cash. Commissions to sales agents and forward selling commissions are up to 1.000% of applicable sales prices. Net proceeds are intended for general corporate purposes, which may include capital expenditures and repayment of indebtedness.
