IAMGOLD FILES FINAL BASE SHELF PROSPECTUS

Iamgold Corp. has obtained a receipt for a final short form base shelf prospectus further to its filing of a preliminary short form base shelf prospectus, previously announced on Aug. 4, 2022. Both documents have been filed with the securities regulators in each province and territory of Canada, and a corresponding registration statement has been filed with the U.S. Securities and Exchange Commission. This filing replaces the previous base shelf prospectus of the company, filed on May 15, 2020.

These filings will allow the company, if it chooses, to make offerings of common shares, first preference shares, second preference shares, debt securities, warrants, subscription receipts, or any combination thereof, of up to $500-million (U.S.) during the next 25 months in Canada and the United States. The company renewed its base shelf prospectus to maintain financial flexibility. The net proceeds from any such offerings may be used by the company to, among other things, finance continuing operations and capital expenditures, including the construction and development of the Cote gold project, reduce its level of outstanding indebtedness from time to time, finance other discretionary capital programs, and for general corporate purposes.

A copy of the final base shelf prospectus included in the registration statement may be obtained from Iamgold Corp., 401 Bay St., Suite 3200, Toronto, Ont., Canada, M5H 2Y4, attention: corporate secretary, or is available on SEDAR and EDGAR.
