IAMGOLD COMPLETES ACQUISITION OF EURO RESSOURCES

Iamgold Corp. has completed, through its wholly owned subsidiary Iamgold France SAS, the acquisition of all of the outstanding common shares of Euro Ressources SA (other than the Euro shares already owned by Iamgold France).

The acquisition was effected by way of Iamgold France's buyout offer followed by a squeezeout in accordance with French law, which was approved by the Autorite des marches financiers on Jan. 23, 2024. Pursuant to the offer, Iamgold, through Iamgold France, acquired 6,249,128 Euro shares, representing approximately 10 per cent of the outstanding Euro shares, at a price of 3.50 euros (C5.13) in cash per Euro share, for aggregate consideration of 21,871,948 euros ($32,066,462) (1).

The purpose of the offer was to enable Iamgold to acquire, through Iamgold France, all of the outstanding Euro shares. Prior to the acquisition, Iamgold, through Iamgold France, beneficially owned and controlled 56,242,153 Euro shares, representing approximately 90 per cent of the outstanding Euro shares. Following the acquisition, Iamgold, through Iamgold France, beneficially owns and controls 62,491,281 Euro shares, representing 100 per cent of the outstanding Euro shares. An early warning report will be filed by Iamgold in accordance with applicable Canadian securities laws and will be available on SEDAR+, or may be obtained directly from Iamgold upon request by contacting Iamgold.

The Euro shares were delisted from the Euronext Paris stock exchange today. Following the delisting, Euro will submit an application to the applicable securities regulators in Canada to cease to be a reporting issuer.

Iamgold appointed Natixis as its financial adviser, the presenting and guaranteeing bank, for the offer. In connection with the offer, Norton Rose Fulbright LLP is acting as French counsel to Iamgold, and Fasken Martineau DuMoulin LLP is acting as Canadian legal counsel to Iamgold.
