The Fort Worth Press - Northern Superior Announces Closing of the Arrangement

As a result of the completion of the Arrangement and the acquisition by IAMGOLD of all of the Company Shares, Northern Superior became a wholly-owned subsidiary of IAMGOLD. Former Northern Superior shareholders are now entitled to receive, in exchange for each Company Share held immediately prior to the effective time of the Arrangement, a combination of (i) 0.0991 of an IAMGOLD common share, and (ii) C$0.19 in cash. The Arrangement also included a distribution to Northern Superior's former shareholders of all the common shares of ONGold Resources Ltd. (the "ONAU Shares") previously held by Northern Superior on the basis of a distribution ratio of 0.19574366 ONAU Share for each Company Share held by the former shareholders of Northern Superior as at December 18, 2025. The Company Shares will be delisted from the TSX Venture Exchange and an application will be made for Northern Superior to cease to be a reporting issuer in Ontario, British Columbia, Alberta and Québec.

"I would like to thank our shareholders for their enduring confidence and support, which have been fundamental to our progress and success. I am equally proud of our team, whose commitment, discipline, and hard work, both over the years and throughout this transaction, have positioned the Company for this meaningful outcome. I also extend my appreciation to our financial and legal advisors, as well as to the IAMGOLD team, for their professionalism and constructive approach during the process," said Simon Marcotte, outgoing President and Chief Executive Officer of Northern Superior. "As I remarked when this transaction was originally made public, IAMGOLD is a company with extraordinary momentum, powered by a leadership team that has flawlessly executed the development of the now-iconic Côté Gold Mine, a highly strategic operation located in one of the world's most sought-after mining jurisdictions. Backed by this unique, repeatedly proven, and Québec-rooted expertise, IAMGOLD will now be able to fully unlock the value of a unified camp and build it into Québec's next major mining complex, with far-reaching economic and social repercussions across the province."

Section 85 Election

Former shareholders who are eligible holders may elect, pursuant to section 85 of the Income Tax Act (Canada) (and any corresponding provisions of any applicable provincial tax legislation), to defer some or all of any capital gain they would otherwise realize on the sale of their respective Company Shares pursuant to the Arrangement (a "Section 85 Election"). Any eligible holder who wishes to make a Section 85 Election may do so by providing a signed copy of the relevant tax election form(s) to IAMGOLD within 120 days of the closing of the Arrangement. Copies of the relevant tax election form(s) will be made available on IAMGOLD's website at www.iamgold.com.
