IAMGOLD Sets the Record Straight on RCF's Overreaching Demands

RCF insists on putting its interests ahead of those of other shareholders with demands that would result in a five percent shareholder taking de facto control of the Company

Toronto, February 2, 2022 - IAMGold Corp. (NYSE: IAG) (TSX: IMG) ("IAMGOLD" or the "Company") today set the record straight on its recent engagement with RCF Management L.L.C ("RCF"), a recent 5.2% shareholder, regarding negotiations between the parties over refreshment of the IAMGOLD board of directors (the "Board"). The Company will provide further updates as developments warrant. In the meantime, there is no need for shareholders to take any action.

IAMGOLD accepted that RCF would nominate three independent directors

IAMGOLD firmly rejects RCF's revisionist narrative regarding its engagement with the Company and the quality of its Board and management team. In fact, the Company engaged openly and constructively with RCF over a period of two weeks, including via meetings with management, Board members, and between legal counsel. IAMGOLD was transparent with RCF about its continuing board renewal process - including the planned departure of its former Board Chair and certain other directors.

In an attempt to avoid the unnecessary cost and distraction of a proxy contest, at the Company's suggestion, the parties entered into a standstill agreement in order to provide requisite time to allow a committee of the Board, as well as the internationally renowned search firm engaged by the Board, to meet with and consider RCF's three director nominees in support of an acceptable resolution.

After completing interviews with RCF's nominees, the committee of the Board and the search firm engaged by the Board independently concluded that two RCF nominees, Maryse Belanger and David Smith, were acceptable, and one, Lawrence Haber, was not. The Board was willing to immediately appoint these two acceptable RCF nominees (Maryse Belanger and David Smith), to replace two IAMGOLD directors. Further, the Board agreed to the appointment of a third independent RCF nominee that was to be reasonably acceptable to the Board. RCF had previously agreed to recommend another nominee, other than Mr. Haber, for appointment to IAMGOLD's Board.

In addition, the Board advised RCF that it was also willing to agree to most of RCF's demands, including:

• Three RCF nominees as new directors of IAMGOLD, as noted above;
• Ensuring an RCF nominee is included as a member of each standing committee of the Board;
• Reconstituting its existing CEO Search Committee such that it would include two existing IAMGOLD directors and two of RCF's nominees; and
• Refraining from concluding its ongoing strategic review of two of its mines and a permanent Chief Executive Officer search until after the Board was reconstituted.

RCF's unacceptable demands

The Board was not willing to accept several overreaching and self-interested RCF demands that would have resulted in a recent 5.2% shareholder taking de facto control of the Company. For example, RCF's demand that Maryse Belanger immediately be appointed Chair, was concerning for a number of reasons, including:

• It is the responsibility and mandate of the Board of Directors, not a recent 5.2% shareholder, to elect its Chair. RCF's demand that Ms. Belanger be immediately installed as Chair without meeting all of the Board members, exposed an alarming disregard for good governance; and
• After due consideration, based on background research and in particular commentary of RCF, the Board became increasingly concerned that Ms. Belanger was not sufficiently independent from RCF to serve as the Chair.

Further, the Board was not willing to agree to additional RCF suggestions and demands, at the expense of the interests of ALL shareholders, including:

• Installing an RCF employee as a Board Observer, providing RCF with unprecedented access and information that no other shareholder would have, without being subject to any of the duties of a director of a publicly traded company;
• Giving RCF's nominees control of certain Board committees and the hiring of IAMGOLD's next CEO;
• Retaining the mining services company Ausenco, which is owned by RCF and retains two RCF co-founders on its board; and
• Paying RCF $1 million to cover the costs of settlement negotiations that lasted mere weeks.

The Company has additional concerns with RCF and its nominees, which it will disclose in due course, but shareholders can rest assured that the Company will continue to defend and advance the best interests of the Company and ALL of its shareholders.

A proxy contest is unnecessary

IAMGOLD is disappointed with RCF's decision to initiate an unnecessary proxy contest and remains open to maintaining a dialogue with RCF and all shareholders and stakeholders. The Board of IAMGOLD made significant efforts to reach a reasonable resolution that is in the interests of the Company and all of its shareholders. Unfortunately, RCF's demands and actions demonstrate that it is focused on what is best for RCF, rather than the best interests of the Company and ALL of its shareholders.

IAMGOLD's focus

IAMGOLD remains firmly focused on becoming a leading high-margin gold producer, through the optimization of its assets and the advancement of Côté Gold towards commercial production, which remains on track for the second half of 2023.

As announced on January 12, 2022 and as part of a refocused strategy, the Company has initiated a strategic review process to explore and evaluate potential strategic alternatives for the Rosebel mine, in addition to the ongoing strategic review of the Westwood mine, in order to focus on maximizing cashflow from value-generating assets, prioritizing capital allocation towards generating the best returns on invested capital and on the development of the Côté Gold project. The Company has not made any decisions related to any specific strategic alternatives at this time and there can be no assurance that the exploration of strategic alternatives will result in a transaction in respect of Rosebel or Westwood.

Ongoing Board Renewal

IAMGOLD is strongly committed to good corporate governance practices and has undertaken initiatives to formally renew the Board with the implementation of a written board renewal guideline in January of 2021. Since the 2020 annual meeting, 57% of the Board (four of seven directors) has been refreshed. These four new Directors are experienced professionals with extensive technical, operations, finance, and environmental and safety expertise. The Board renewal process is robust and ongoing and includes the search for a new CEO and Chair, with the assistance of professional executive search firms.

ADVISORS

The Board has engaged TD Securities as financial advisor, Longview Communications and Public Affairs is engaged as communications advisor, Morrow Sodali as proxy solicitation agent and strategic advisor and Davies Ward Phillips & Vineberg LLP and Paul, Weiss, Rifkind, Wharton & Garrison LLP as legal advisors,.
