MESSAGE FROM THE CHAIR OF THE BOARD OF DIRECTORS

April 6, 2023

Dear Shareholders,

On behalf of the Board of Directors and management of IAMGOLD Corporation, I would like to invite you to attend the annual meeting of shareholders that will be held on Thursday, May 11, 2023, at 11:00 a.m. (EDT). In order to permit a greater number of shareholders to participate, the annual meeting will be held in virtual format, conducted via live audio webcast, as set out in further detail in the accompanying notice and management information circular.

The enclosed management information circular contains important information about the annual meeting and the business to be conducted, including voting, and the individuals nominated to serve as directors. The Circular also outlines the Board’s role and responsibilities, our corporate governance practices and how we compensate our executives and directors.

IAMGOLD made significant strides last year towards our goal of becoming a leading high-margin gold producer. These achievements were made possible by the dedication and resiliency of our employees at every level of the company who demonstrated a commitment to working safely and responsibly towards a shared vision of generating superior value for our stakeholders through accountable mining. As we look forward, 2023 will be a pivotal year for the Corporation, with a strong focus on continuing to execute at the Côté Gold Project in Ontario, Canada. We remain on track to commence production at Côté early next year and are eager to showcase what will be Canada’s third largest gold mine by production. At our operations, we will continue to focus on safety, productivity and predictability with a steadfast commitment to responsible mining and Zero Harm^®.

Your participation in the affairs of the Corporation is important to us. We encourage you to exercise your vote, either online at the meeting, by completing and returning your proxy form by telephone or online in advance of the meeting.

We hope you can join us via the webcast on May 11, 2023.

Sincerely,

Maryse Bélanger

Chair of the Board of Directors

2023 Management Proxy Circular IAMGOLD  |  1

A SPOTLIGHT ON ENVIRONMENTAL, SOCIAL AND GOVERNANCE

IAMGOLD has focused on enhancing its ESG practices in recent years, which has resulted in strong performance and public recognition of its achievements. Rooted in IAMGOLD’S ESG practices, Zero Harm^® is the commitment to continually strive to reach the highest standards in health and safety, minimize the Corporation’s environmental footprint, and work co-operatively with its host communities (See also “Statement of Corporate Governance Practices – Environmental, Social and Corporate Governance”).

ESG and the Link to Compensation

IAMGOLD’s commitment to Zero Harm^® is the core of the Corporation’s brand, and health, safety, environment and community practices are the foundation upon which it operates. In 2022, the Corporation reinforced its commitment to ESG practices by introducing more rigorous ESG metrics for the purposes of CIP awards with Health, Safety and Sustainability metrics representing 20% of the Company Scorecard.

ESG Governance has been strengthened with the board of directors responsible for overseeing ESG strategy, governance and risk, while at management-level, the ESG organization lead by the SVP External Affairs and Sustainability has been redesigned with a cross-functional ESG structure, with clearer mandates and accountabilities on Health, Safety, Environment matters and Local Community risks and impacts (HSEC) arising out of the Corporation’s activities.

2022 Recognition Awards

• IAMGOLD continues to be recognized among its peers by Corporate Knights which identifies the top 50 Canadian corporate citizens across all sectors evaluated based on ESG and economic key performance indicators. From a pool of 332 firms, the Corporation was 37th on the Best 50 list on June 29, 2022, an improvement of seven places over the prior year.

• In Moody’s ESG Solutions, IAMGOLD was ranked 5th out of 52 sector peers, with notable strengths in social and economic development, environmental strategy, health & safety and governance.

• IAMGOLD rating of AA by the MSCI ESG Rating assessment was reaffirmed in 2022, placing the Corporation among the top 15% of precious metals companies within the assessment.

• IAMGOLD was recognized as a 2023 Greater Toronto Area Top Employer.

• The Corporation obtained the ECOLOGO^® certification for its mineral exploration activities carried out in Quebec and is the first producing mining company to achieve such certification.

Environment

Priority will be given to updating and approving, by end of Q3 2023, the Corporation’s decarbonization strategy (GHG reduction and biodiversity plan) aiming at reducing greenhouse gas emissions and achieving operational efficiencies. Decarbonization will be integrated into the Corporation’s business planning process. With regard to tailings and water stewardship and to ensure TSM Level A at all sites, major initiatives will be implemented during the year, including: a revamped Environmental Management System (EMS) as well as new technical standards on tailings, water, biodiversity, and waste rock ore pile and a particular attention will be paid to the development of integrated mine closure plans, especially for Essakane and Westwood, in order to start or continue with the comprehensive implementation of environmental rehabilitation programs and social transition initiatives to support future mine closure.

The Corporation will timely publish all external reports such as SASB and GRI-aligned Sustainability Report and will continuously monitor new and emerging reporting obligations to meet new regulatory and stakeholder’s expectations.

2023 Management Proxy Circular IAMGOLD  |  2

Social

With regard to health and safety, based on the 2022-2024 health and safety roadmap, 2023 initiatives will focus on leadership and culture; critical risks and controls via the deployment of new or revamped health and safety standard and specific preventive programs; systems and technology strengthening; learning and improvement.

Maintaining special relationships and trusts with our host communities and managing emerging community-related risks will be a key focus area in 2023. This will involve strengthening existing relationships with communities of interest, promoting effective communications to support positive relationships, managing stakeholder expectations, and improving the definition of corporate expectations related to community and Indigenous relations. New corporate community relations standards and policies related to stakeholder engagement, community investment, and local content will be developed and implemented at each site. Level A in TSM Indigenous and Community Relations Protocol will be sought across the Corporation and efforts will continue with strategic partnerships with Global Affairs Canada, One Drop, Giants of Africa and the UNDP to leverage for positive and lasting benefits.

Equity, Diversity and Inclusion (EDI)

EDI is an important topic for IAMGOLD, across all geographies, departments and levels of the Corporation. Inclusion can unlock the potential of diversity, recognizing that when people feel that they belong in a workplace there is higher employee engagement, which can lead to innovative ideas and practices, enhanced creativity, supportive problem-solving and more insightful decision-making. The EDI Steering Committee, led by executive champions, provides strategic direction for this initiative and helps maintain focus and drive positive results for the Corporation while creating more opportunities.

2022 EDI Achievements

In 2022, IAMGOLD engaged in several initiatives to advance equity, diversity and inclusion imperatives, aligned to corporate values, and in response to results from an EDI diagnostic completed in the previous year.

Progress in 2022 included several key actions to reinforce IAMGOLD’S commitment to EDI:

• EDI awareness workshops were implemented for all leaders globally, specifically focused on the topic of Conscious Inclusion, building awareness surrounding leadership’s role in creating a more inclusive work environment.

• A strategy to promote a safe and supportive workplace free of physical and psychological hazards was developed and deployed in close partnership with Health & Safety. This included an updated Health & Safety policy to include both physical and psychological safety elements, as well as the development of learning modules for employees globally on the topic of psychological safety.

• As a Canadian business committed to responding to the Truth and Reconciliation Commission of Canada’s Calls to Action, the Corporation continues to take meaningful action towards reconciliation by fostering long-term, mutually beneficial relationships with our Indigenous partners and offering our employees opportunities for continued learning. Côté Gold’s commitments to Indigenous training and hiring through the Impact Benefit Agreements with Mattagami First Nation, Flying Post First Nation, and, the Métis Nation of Ontario, Region 3, includes working to ensure any barriers identified to employment are reviewed and where possible, resolved.

GENERAL PROXY INFORMATION

SOLICITATION OF PROXIES

The information contained in this management information circular (“Circular”) is furnished in connection with management’s solicitation of proxies to be used at the annual meeting (the “Meeting”) of holders (“Shareholders”) of common shares (the “Common Shares”) of IAMGOLD Corporation (the “Corporation” or “IAMGOLD”), to be held in a virtual-only format, which will be conducted via live audio webcast online at https://meetnow.global/MJRV6TK, on Thursday, May 11, 2023 at 11:00 a.m. (EDT), for the purposes set out in the accompanying notice of the Meeting (the “Notice of Meeting”).

A summary of the information Shareholders will need to attend the Meeting online is provided below. A guide on to how to login, and vote at, the Meeting was mailed to Registered Shareholders together with this Circular and can be found on the Corporation’s issuer profile on SEDAR at www.SEDAR.com and EDGAR at www.SEC.gov.

It is expected that management’s solicitation of proxies for the Meeting will be made primarily by mail; however, directors, officers and employees of the Corporation may also solicit proxies by telephone, electronically or in person in respect of the Meeting. This solicitation of proxies for the Meeting is being made by or on behalf of the directors and management of the Corporation and the Corporation will bear the costs of this solicitation of proxies for the Meeting. The Corporation is not sending proxy-related materials directly to beneficial owners of Common Shares. The Corporation will reimburse brokers and nominees for their reasonable expenses in forwarding proxies and accompanying materials to beneficial owners of Common Shares.

INFORMATION FOR REGISTERED SHAREHOLDERS

Enclosed with this Circular is a form of proxy. The persons named in the enclosed form of proxy are officers and/or directors of the Corporation. Shareholders may appoint a person (who need not be a Shareholder of the Corporation) other than the persons already named in the enclosed form of proxy to represent such Shareholder at the Meeting by striking out the printed names of such persons and inserting the name of such other person in the blank space provided therein for that purpose.

In order to be valid, a proxy must be received by Computershare Trust Company of Canada, 8th Floor, 100 University Avenue, Toronto, Ontario, M5J 2Y1, no later than 11:00 a.m. (EDT) on May 9, 2023 or, in the event of an adjournment or postponement of the Meeting, no later than 48 hours (excluding Saturdays, Sundays and holidays) before the time for holding the adjourned or postponed Meeting.

As noted in the Notice of Meeting accompanying this Circular, Registered Shareholders may also elect to vote electronically in respect of any matter to be acted upon at the Meeting. Voting instructions provided electronically are in all respects equivalent to, and will be treated in the exact same manner as, voting instructions provided via a paper form of proxy. To vote electronically, Registered Shareholders are asked to go to the website shown on the form of proxy and follow the instructions on the screen. Please note that Shareholders exercising the electronic voting option will need to refer to the control number indicated on their proxy form to identify themselves in the electronic voting system. Shareholders should also refer to the instructions on the proxy form for information regarding the deadline for voting Common Shares electronically. If a Shareholder votes electronically, they are asked not to return the paper form of proxy by mail.

In order to be effective, a form of proxy must be executed by a Shareholder exactly as their name appears on the register of shareholders of the Corporation. Additional execution instructions are set out in the notes to the form of proxy. The proxy must also be dated where indicated. If no date is indicated, the proxy will be deemed to be dated on the day on which it was mailed to Shareholders.

The management representatives designated in the enclosed form of proxy will vote the Common Shares in respect of which they are appointed proxy in accordance with the instructions of the Shareholder as indicated on the proxy and, if the Shareholder specifies a choice with respect to any matter to be acted upon, the Common

2023 Management Proxy Circular IAMGOLD  |  8

Shares will be voted accordingly. In the absence of such direction, such Common Shares will be voted by the management representatives named in such form of proxy in favour of each of the matters referred to in the Notice of Meeting and will be voted by such representatives on all other matters which may come before the Meeting in their discretion.

The enclosed form of proxy, when properly signed, confers discretionary voting authority on those persons designated therein with respect to amendments or variations to the matters identified in the Notice of Meeting and with respect to other matters which may properly come before the Meeting. At the date of this Circular, management of the Corporation does not know of any such amendments, variations or other matters. However, if such amendments, variations or other matters which are not now known to management of the Corporation should properly come before the Meeting, the persons named in the enclosed form of proxy will be authorized to vote the Common Shares represented thereby in their discretion.

INFORMATION FOR NON-REGISTERED SHAREHOLDERS

Only Registered Shareholders of the Corporation or persons duly appointed as proxies are entitled to attend and vote at the Meeting. However, in many cases, Common Shares beneficially owned by a person (a “Non-Registered Shareholder”) are registered either:

• In the name of an intermediary (an “Intermediary”) with whom the Non-Registered Shareholder deals in respect of the Common Shares (Intermediaries include, among others, banks, trust companies, securities dealers or brokers, trustees or administrators of a self-administered registered retirement savings plan, registered retirement income fund, registered education savings plan and similar plans); or

• In the name of a clearing agency (such as The Canadian Depository for Securities Limited, in Canada, or The Depositary Trust Company, in the United States) of which the Intermediary is a participant.

In accordance with the requirements of National Instrument 54-101 – Communication with Beneficial Owners of Securities of a Reporting Issuer of the Canadian Securities Administrators, the Corporation has distributed copies of the Notice of Meeting, this Circular and a form of proxy (collectively, the “Meeting Materials”) to the Intermediaries and clearing agencies for onward distribution to Non-Registered Shareholders. Intermediaries are required to forward the Meeting Materials to Non-Registered Shareholders unless the Non-Registered Shareholders have waived the right to receive them. Intermediaries often use service companies to forward the Meeting Materials to Non-Registered Shareholders. Generally, Non-Registered Shareholders who have not waived the right to receive Meeting Materials will either be given:

• A voting instruction form (a “VIF”) which must be completed and returned by the Non-Registered Shareholder in accordance with the directions printed on the form (in some cases, the completion of the VIF by telephone, facsimile or over the internet is permitted); or

• A form of proxy which has already been signed by the Intermediary (typically by a facsimile, stamped signature), which is restricted as to the number of Common Shares beneficially owned by the Non-Registered Shareholder but which is otherwise not completed by the Intermediary. Because the Intermediary has already signed the form of proxy, this form of proxy is not required to be signed by the Non-Registered Shareholder when submitting the proxy. In this case, the Non-Registered Shareholder who wishes to submit a proxy should properly complete the form of proxy and deposit it with Computershare Trust Company of Canada, 8th Floor, 100 University Avenue, Toronto, Ontario, M5J 2Y1, by the proxy deadline.

In either case, the purpose of these procedures is to permit Non-Registered Shareholders to direct the voting of the Common Shares they beneficially own. Should a Non-Registered Shareholder who receives either a form of proxy or VIF wish to attend the Meeting virtually and vote (or have another person attend and vote on behalf of the Non-Registered Shareholder), the Non- Registered Shareholder should, in the case of a form of proxy, strike

2023 Management Proxy Circular IAMGOLD  |  9

out the names of the persons named in the form of proxy and insert the Non-Registered Shareholder’s (or such other person’s) name in the blank space provided or, in the case of a VIF, follow the directions indicated on the form. In either case, Non-Registered Shareholders should carefully follow the instructions of their Intermediaries and their service companies, including instructions regarding when and where the proxy or VIF is to be delivered.

2023 Management Proxy Circular IAMGOLD  |  10

SPECIAL PROCEDURES FOR THE VIRTUAL-ONLY MEETING

Please read the below very carefully as it contains important information related to the Corporation’s virtual-only Meeting.

Registering a Proxyholder

Shareholders who wish to appoint a third-party proxyholder to virtually attend, participate or vote at the Meeting as their proxy and vote their Common Shares MUST submit their proxy or VIF, as applicable, appointing such third-party proxyholder AND registering the third-party proxyholder, as described below. Registering your proxyholder is an additional step to be completed AFTER you have submitted your proxy or VIF. Failure to register the proxyholder will result in the proxyholder not receiving a 4-character Invite Code to virtually attend, participate or vote at the Meeting.

Step 1: Submit your proxy or VIF

• To appoint a third-party proxyholder, insert such person’s name in the blank space provided in the form of proxy or VIF (if permitted) and follow the instructions for submitting such form of proxy or VIF. This must be completed prior to registering such proxyholder, which is an additional step to be completed once you have submitted your form of proxy or VIF.

By doing so, you are instructing your Intermediary to appoint you as proxyholder. It is important that you comply with the signature and return instructions provided by your Intermediary.

If you are a Non-Registered Shareholder located in the United States and wish to attend, participate or vote at the Meeting or, if permitted, appoint a third party as your proxyholder, in addition to the steps described above and below under the heading “Attending and Participating at the Meeting”, you must obtain a valid legal proxy from your Intermediary.

Follow the instructions from your Intermediary included with the legal proxy form and the VIF sent to you, or contact your Intermediary to request a legal proxy form or a legal proxy if you have not received one. After obtaining a valid legal proxy from your Intermediary, you must then submit such legal proxy to Computershare Trust Company of Canada at uslegalproxy@computershare.com, by 11:00 a.m. (EDT) on May 9, 2023 (or, if the Meeting is adjourned or postponed, by the time that is 48 hours prior to the Meeting, excluding Saturdays, Sundays and holidays).

VOTING SECURITIES AND PRINCIPAL HOLDERS THEREOF

DESCRIPTION OF SHARE CAPITAL AND QUORUM

The Corporation is authorized to issue an unlimited number of Common Shares. Each Common Share entitles the holder of record to notice of and one vote at all meetings of Shareholders. As at the close of business on April 6, 2023, there were 480,929,765 Common Shares outstanding. The presence of two or more persons entitled to vote at the Meeting, either as Shareholders or proxy holders, and holding or representing not less than 25% of the issued and outstanding Common Shares entitled to be voted thereat will constitute a quorum for the Meeting.

RECORD DATE

The directors of the Corporation have fixed the close of business on April 6, 2023, as the record date for the determination of those holders of Common Shares entitled to receive notice of the Meeting and to vote at the Meeting including at all adjournments or postponements thereof.

OWNERSHIP OF SECURITIES OF THE CORPORATION

As of April 6, 2023, to the knowledge of the directors and officers of the Corporation, and according to securities regulatory filings of which the Corporation has notice, no person or company, beneficially owned, or exercised control or direction over, more than 10% of the votes attached to all of the Common Shares outstanding.

CURRENCY

Unless stated otherwise, all references to dollar amounts in this Circular are to Canadian dollars. The average annual exchange rate for 2022 reported by the Bank of Canada of CAD$1.00 = US$0.7692 was used, unless otherwise noted.

2023 Management Proxy Circular IAMGOLD  |  14

BUSINESS OF THE MEETING

ELECTION OF DIRECTORS

Shareholders will be asked to elect eight (8) directors:

• Renaud Adams;

• Ian Ashby;

• Maryse Bélanger;

• Christiane Bergevin;

• Ann Masse;

• Peter O’Hagan;

• Kevin O’Kane; and

• David Smith

Each director elected will hold office until the close of the next annual meeting of the Shareholders of the Corporation, unless their office is earlier vacated or until their successor is appointed or elected. See “Board of Directors”.

Recent amendments to the Canada Business Corporations Act (the “CBCA”), the Corporation’s governing statute, provide Shareholders with a statutory right to vote for or against director nominees during uncontested elections. If any director nominee does not receive a majority of votes in favour of their election, such director nominee will not be elected to serve as a member of the Board. Any nominee that is an incumbent director who does not receive a majority of votes in their favour may remain in office until the earlier of (i) the 90th day after the date of the election; and (ii) the day on which their successor is appointed or elected.

Because of the amendments to the CBCA, the Corporation has repealed its Majority Voting Policy. Under the terms of the former Majority Voting Policy, any director nominee for whom a majority of shares voted in an election were withheld would, subject to the very limited discretion of the Board, not be accepted as a director (despite being duly elected as a matter of corporate law) and would be required to immediately tender their resignation to the Board, which resignation would be accepted and effective, absent exceptional circumstances, within 90 days of the Shareholder meeting. See also “Statement of Corporate Governance Practices – Statutory Majority Voting”.

The Board recommends that Shareholders vote FOR the election of each of the nominees set out in this Circular. Management of the Corporation does not contemplate that any of the nominees will be unable to serve as a director of the Corporation for the ensuing year; however, if that should occur for any reason at or prior to the Meeting or any adjournment or postponement thereof, the persons named in the enclosed form of proxy have the right to vote the proxy for the election of the remaining nominees and may vote in their discretion for the election of any persons in place of any nominees unable to serve.

In the absence of any instruction to vote against the election of any nominee, the Common Shares represented by proxies received by management will be voted FOR each of the nominees set out in this Circular. The elected directors will hold office until the close of the next annual meeting of Shareholders, unless their office is earlier vacated or until their successor is appointed or elected.

Information as to the number of Common Shares owned and/or over which control or direction is exercised, whether directly or indirectly, by the nominees for election as directors of the Corporation is, in each case, based upon information furnished by the respective nominee on the System for Electronic Disclosure by Insiders (“SEDI”), at www.sedi.ca, and information otherwise available to the Corporation as at April 6, 2023.

ADVISORY VOTE ON THE CORPORATION’S APPROACH TO EXECUTIVE COMPENSATION

The Board has adopted a shareholder advisory vote on the Corporation’s approach to executive compensation, as disclosed under the heading “Statement of Executive Compensation”. As a formal opportunity to provide their views on the disclosed objectives and structure of the Corporation’s pay-for-performance compensation model, Shareholders are asked to review and vote, in a non-binding, advisory manner, on the following resolution:

Resolved that, on an advisory basis and not to diminish the role and responsibilities of the board of directors, the shareholders accept the approach to executive compensation disclosed in the management information circular of IAMGOLD Corporation dated April 10, 2023.

The Human Resources and Compensation Committee (the “HRCC”) and the Board will take the results of the vote into account, as appropriate, when considering future compensation policies, procedures and decisions, all of which are to be consistent with its pay-for-performance compensation model (see the Statement of Executive Compensation for details regarding the compensation philosophy and guidelines of the Board and the performance metrics and process used to assess performance as well as whether any compensation consultant was retained). The pay-for-performance compensation model is designed to attract, retain and motivate talented management and pay for actual performance which drives the long-term creation and preservation of shareholder value.

The Board recommends that Shareholders vote FOR the resolution to accept the Corporation’s approach to executive compensation.

In the absence of any instruction to the contrary, the Common Shares represented by proxies received by management will be voted FOR the approval of the resolution to accept the Corporation’s approach to executive compensation.

For Additional Detail

See Appendix “B” to this Circular for the voting results at the annual meeting of Shareholders held on May 3, 2022 on the matters comprising the business of the Meeting, as applicable. A simple majority of votes cast for, or in favour of, a matter will constitute approval of that matter.

COLLABORATION AGREEMENT

On February 13, 2022, the Corporation entered into a collaboration agreement (the “Collaboration Agreement”) with RCF Management L.L.C. and Resource Capital Fund VII L.P. (collectively, “RCF”), pursuant to which the Corporation and RCF agreed to certain matters regarding the governance processes and constitution of the Board.

Pursuant to the Collaboration Agreement, the Corporation agreed to (i) immediately appoint Ms. Bélanger, Mr. Smith and Mr. Ashby to the Board, (ii) to appoint Ms. Bélanger as the Board Chair concurrently with the execution of the Collaboration Agreement, and (iii) to conduct a search process for an additional independent nominee, which was completed in March 2022 and resulted in the appointment of Mr. O’Hagan. The Corporation also agreed to form an ad hoc CEO Search Committee composed of Mr. Smith, Ms. Bélanger and Mr. O’Kane, which resulted in the appointment of Renaud Adams as President and CEO of the Corporation on March 6, 2023, effective as of April 1, 2023.

RCF is also subject to certain customary standstill restrictions and voting commitments from the date of the Collaboration Agreement until the earlier of (i) the day following the completion of all business to be conducted at the Meeting and the termination thereof and (ii) December 31, 2023 (the “Standstill Period”).

Prior to the expiration of the Standstill Period, the Corporation agreed that the Board will consist of no more than nine (9) directors, with one of the directors to be the CEO following the appointment of the new CEO at the conclusion of the CEO search process, and the Corporation will not decrease the size of the Board if such decrease would require the resignation of any of Ms. Bélanger or Messrs. Ashby, O’Hagan or Smith.

Additionally, at (A) each of the Corporation’s 2022 annual meeting of shareholders and the Meeting and (B) any special meeting of Shareholders held prior to the expiration of the Standstill Period at which the election of directors is considered, the Corporation agreed to (1) include Ms. Bélanger and Messrs. Ashby, O’Hagan and Smith (or their substitutes appointed pursuant to the Collaboration Agreement) on the Corporation’s slate of director candidates, (2) nominate and reflect in the management information circular and form of proxy for each such meeting the nomination of each such individual for election at each such meeting, (3) cause all valid proxies received by the Corporation to be voted in the manner specified by such proxies and, to the extent permitted under applicable law and stock exchange rules, cause all such proxies for which a vote is not specified in respect of the election of directors to be voted in favour of the election of each such individual and (4) solicit proxies in favor of and otherwise support the election of each such individual no less than the manner in which the Corporation supports its other nominees for election at any such meeting.

The Collaboration Agreement also provides that if any of Ms. Bélanger or Messrs. Ashby or Smith ceases to be a director for any reason prior to the end of the Standstill Period, and so long as RCF has not ceased to beneficially own in the aggregate at least 2.5% of the Corporation’s then-outstanding Common Shares, then RCF may designate a substitute person to serve on the Board who meets certain independence requirements, in accordance with the terms of the Collaboration Agreement. In the event that Mr. O’Hagan ceases to be a director for any reason prior to the end of the Standstill Period, and so long as RCF has not ceased to beneficially own in the aggregate at least 2.5% of the Corporation’s then-outstanding Common Shares, the Collaboration Agreement provides that RCF may recommend a substitute nominee to the NCGC for consideration for appointment to the Board.

CEASE TRADE ORDERS AND BANKRUPTCIES

Other than as set forth below, to the Corporation’s knowledge, as at the date of the Circular, or within the last ten years, no proposed director of the Corporation is or has been:

a) a director, chief executive officer or chief financial officer of any company (including the Corporation):

i. subject to an order (including a cease trade order, an order similar to a cease a trade order or an order that denied the relevant company access to any exemption under securities legislation) for a period of more than 30 consecutive days, that was issued while the proposed director was acting in the capacity as director, chief executive officer or chief financial officer; or

ii. subject to an order (including a cease trade order, an order similar to a cease trade order or an order that denied the relevant company access to any exemption under securities legislation) for a period of more than 30 consecutive days, that was issued after the proposed director ceased to be a director, chief executive officer or chief financial officer and which resulted from an event that occurred while that person was acting in the capacity as director, chief executive officer or chief financial officer; or

b) a director or executive officer of any company (including the Corporation), that while that person was acting in that capacity or within a year of the person ceasing to act in that capacity, became bankrupt, made a proposal under any legislation relating to bankruptcy or insolvency or was subject to or instituted any proceedings, arrangement or compromise with creditors or had a receiver, receiver manager or trustee appointed to hold its assets.

Ms. Bélanger served as a director of Mirabela Nickel Limited (“Mirabela”), an Australian Stock Exchange (“ASX”) listed company, until July 2016. In September 2015 the directors of Mirabela made the decision to put the company into voluntary administration as it became apparent that the company was unable to continue as a going concern. Additional third-party financing was unable to be secured because of the decline in global nickel prices. This made it economically impossible for the company to continue trading on the ASX.

Ms. Bélanger served as a director of Plateau Energy Metals Inc. (“Plateau”), a TSX Venture Exchange-listed company, until May 11, 2021, the date on which all of the issued and outstanding shares of Plateau were acquired by American Lithium Corp. by way of a court-approved plan of arrangement. On March 15, 2021, Plateau announced that it was the subject of an investigation by the Ontario Securities Commission (the “OSC”). On May 3, 2021, the OSC filed a Statement of Allegations against Plateau, its former CEO and its CFO alleging, among other things, that Plateau had made certain misleading statements in its public disclosure. On June 1, 2022, the OSC imposed a cease trade order on Plateau as result of its failure to file certain continuous disclosure documents. Such cease-trade order remains in effect as of the date hereof.

Ms. Bélanger served as a director of Pure Gold Mining Inc. (“Pure Gold”), which obtained an initial order for creditor protection from the Supreme Court of British Columbia under the Companies’ Creditors Arrangement Act (“CCAA”) on October 31, 2022. The decision to commence CCAA proceedings was made in light of Pure Gold’s cash position, scheduled debt payments, forecast revenue and expenses and all available alternatives to an application for creditors’ protection. On November 9, 2022, the Court, on application by Pure Gold, granted a Sales and Investment Solicitation Process Order (the “SISP Order”), among other relief. The SISP Order, among other things: (i) approves a sales and investment solicitation process for all the assets, undertakings and property of Pure Gold, including the Pure Gold Mine project located in Red Lake, Ontario (the “SISP”) and (ii) approves of the engagement of a financial institution to act as Pure Gold’s sales agent for the purposes of the SISP.

STATEMENT OF EXECUTIVE COMPENSATION

MESSAGE FROM THE HUMAN RESOURCES AND COMPENSATION COMMITTEE

Dear Fellow Shareholders:

In 2022, IAMGOLD continued its transformational journey. Our refreshed leadership team and Board continued their commitment to our goal of becoming a leading high-margin gold producer. At IAMGOLD, we are focused on advancing our culture of teamwork and accountability. The engaged management team has been committed to “doing what we said we were going to do,” realizing significant successes in 2022 including the funding of the construction of the Côté Gold Project and exceeding production guidance for the year. We believe that this is a testament to the strength of our team and our culture.

Leadership Transition

With a new Board and interim replacements for the CEO and CFO through much of the year, the Board and management worked diligently and collaboratively to advance IAMGOLD’s strategy, while implementing a robust succession planning process and rebuilding our executive leadership team.

The progress made in strengthening IAMGOLD in 2022 sets an excellent base for our future success under the leadership of our new President and CEO, Renaud Adams, who was appointed effective April 1, 2023. Renaud offers the exceptional combination of operational, strategic and capital markets experience, with a proven track record of leading a safety-first culture, attributes that are essential for leading a global mining company today. In addition, the announcement of the permanent appointment of Maarten Theunissen as CFO exemplifies the Corporation’s commitment to advancing talent through its succession planning program.

Aligned Objectives Driving Results

We believe long-term incentives serve to align executives with shareholders, and pride ourselves on having a strong alignment with pay-for-performance in our executive compensation programs, with the largest component of executive compensation being our long-term Equity Incentive Plan, of which 50% requires specific performance achievements to vest.

Also, important to enhancing the alignment of our pay and performance is our annual Cash Incentive Plan that focuses on the achievement of near-term objectives related to executing our strategic plan. In 2022, the following were captured in the Company Scorecard with actual performance for the year resulting in an overall score of 131.8% of target:

• Project Advancement and Financing (50%): The 2022 scorecard is weighted towards measures driving the management and successful completion of the Côté Gold Project reflecting the importance of advancing Côté to the future of IAMGOLD. Our above target performance (148% of target) resulted from completion of the project review and risk analysis, securing the financing package required for construction completion to allow the project to continue on schedule without impact to economics, and exceeding our operational readiness targets by completing mechanical assemblies ahead of schedule.

The successful achievement of our objectives required a high and continuing degree of teamwork, and we are placing a similar emphasis in 2023 as we complete construction and prepare for first production in early 2024.

• Delivering on Guidance (30%): While laying the foundations for future success with Côté, management improved the performance of our operating mines culminating in production and costs beating our 2022 guidance targets. Overall, delivering on our guidance as it relates to operations was weighted 30% of our Company Scorecard, with management achieving above target performance (147%).

2023 Management Proxy Circular IAMGOLD  |  28

• ESG (20%): We continue to place significant importance on ESG – with categories for equity, diversity and inclusion (“EDI”), environment, and safety – representing in aggregate 20% of our Company Scorecard. Despite the successes we had, including surpassing over 9 million hours without a lost time injury at Côté, we experienced the tragic loss of one of our team members in Burkina Faso. As a result, we adjusted our Safety DART performance to zero in the Company Scorecard and conducted a thorough investigation of the incident while implementing improvements to prevent future recurrences all in accordance with the Corporation’s commitment to our Zero Harm^® principle. Overall, performance in the ESG category was below target (68%) for 2022.

Opportunity to Reset

In 2022, the Committee and leadership team focused on advancing a resilient culture with teamwork and accountability at the center of everything we do. We reset and reassessed our compensation programs and governance practices, making a number of changes to our peer group and updated our executive contract template to align with current market practices and shareholder interests. We also revamped our formal succession planning process and reviewed broader programs from an EDI perspective to create a more inclusive benefits suite.

Looking Ahead

We are excited about the future of IAMGOLD and the opportunities that lie ahead especially with the advancement of the Côté Gold Project towards production in early 2024. We are confident that the progress made in strengthening IAMGOLD in 2022 sets an excellent foundation for 2023 and beyond, as we work together to deliver our commitments to shareholders, our colleagues, and our communities. As always, we welcome your feedback on our compensation programs and look forward to your continued support.

Sincerely,

Anne Marie Toutant (Chair)

Christiane Bergevin

The Corporation will achieve this vision through operational excellence, profitability and financial capacity while reinforcing our commitment to strong environmental, social and governance practices.

To further this vision, IAMGOLD commits to effectively link compensation to realized business results. The fundamental objective of IAMGOLD’s executive compensation approach is to motivate and reward executives to create and preserve shareholder value over the long-term alongside our commitment to serve the interests of the Corporation’s stakeholders as a whole.

2023 Management Proxy Circular IAMGOLD  |  30

Guiding Principles

To attain these objectives, the Corporation’s executive compensation program and policy decisions are guided by the following principles:

Benchmarking

The Corporation’s executive compensation programs are benchmarked against similar organizations to attract and retain global talent and remain competitive in markets where the Corporation operates, targeting market median compensation for fully functioning incumbents for expected levels of performance. The market data are used as a reference point, along with other factors, to which the HRCC compares the compensation of each executive to the Peer Group to set executive compensation levels commensurate with performance and experience level. The Peer Group is also used as a benchmark for compensation trends and market practices.

Peer Group

The HRCC works with WTW (the Committee’s independent compensation consultant, whose role is discussed further in “Compensation Program Oversight”) to create and maintain an appropriate peer group of relevant companies for comparison purposes. Each year, as part of a regular process the composition of the Peer Group is reviewed to determine if any changes are required. The Corporation considers organizations that are similar in size and scope of operations and are representative of the market within which it competes for executive talent. When selecting comparators, the Corporation applies the following established criteria:

Factors	Selection Criteria
Industry	Companies with active mining operations with an emphasis on gold miners and multiple mine sites
Geography	Headquartered in North America with international operations
Size	Revenue within one-third to three times that of IAMGOLD
Corporate Structure	Publicly traded on the TSX

2023 Management Proxy Circular IAMGOLD  |  31

The HRCC reviewed the 2022 Peer Group and made changes to include more appropriately sized organizations. Specific adjustments included:

• Removing Agnico Eagle and Kirkland Lake due to recent merger and resulting size relative to IAMGOLD

• Adding Dundee Precious Metals, Equinox Gold, Lundin Gold and Pan American Silver

IAMGOLD’s revenue is positioned at the 50th percentile of the new Peer Group

Components of Executive Compensation

IAMGOLD provides a competitive compensation program to its executives to attract and retain key talent to deliver on our long-term strategic plan.

	Element	Objectives	Design
Total Direct Compensation
	Base Salary	•  Recognize and reward skills, experience, and level of responsibility	Base salary is determined at the beginning of the fiscal year and considers several factors: •  Scope, complexity, and responsibility of the role •  Competitiveness with salary levels for similar-sized positions within the Peer Group •  Individual experience and sustained performance level Comparative market analysis and individual performance assessments occur annually to ensure compensation remains competitive, resulting in periodic base salary adjustments, when appropriate. Annual base salary increases are not guaranteed.
	Cash Incentive Plan (CIP)	•  Motivate the achievement of annual objectives •  Reward performance that supports the business strategy	CIP awards are based on the annual achievement of balanced scorecard performance objectives, representing a combination of financial, operational, growth, and ESG that can vary each year based on near term priorities, and individual performance goals. Challenging performance targets are pre-defined in conjunction with the annual budgeting process. •  The target CIP level is set as a percentage of base salary. •  Award values range from 0% for below threshold performance to a maximum of 200% of the target value, depending on the actual performance achieved. The HRCC reviews performance results and may apply their informed judgment to ensure final award values reflect shareholder experience. CIP awards are performance-based and therefore the Corporation does not guarantee such payments to its executives.
	Equity Incentive Plan (EIP)	•  Motivate the sustained achievement of long-term goals •  Reward performance that is aligned with the creation of long-term shareholder value •  Align executives’ share ownership with shareholder experience	EIP grants have staggered and overlapping vesting schedules to ensure that executives continually focus on future value creation. Target grant value is expressed as a percentage of base salary. In determining the actual individual grants, the HRCC considers a series of key indicators to determine an EIP scoring factor between 80% and 120% of the target value. The equity grant is then allocated based on a target mix as follows: •  50% performance share units – 3-year cliff vesting dependent on company performance achievement •  25% restricted share units – 3-year cliff vesting •  25% options – 7-year term, vesting over 5 years (20% per year starting on first anniversary) Performance share units (PSUs) vest conditionally on 3-year relative TSR (75%) and ROIC (25%), which were selected as key indicators of long-term growth and value creation. All EIP awards are granted based on performance and ultimate vesting and value achieved requires continued employment and achievement of performance targets for PSUs and share price increases therefore the Corporation does not guarantee any EIP awards to its executives.
Indirect Compensation
	Benefits, Pension, and Perks	•  Provide benefits coverage and retirement savings for the wellbeing of executives	Executives participate in the same benefits provided to all employees which includes health, dental and life insurance benefits, a defined contribution pension plan and a share purchase plan. Top-up disability insurance coverage, annual health risk assessments and taxable perquisites are also provided to executives, according to their employment agreements, as disclosed in the footnotes to the Summary Compensation Table. The Corporation does not provide any loans to its executives.

2023 Management Proxy Circular IAMGOLD  |  33

Target Total Direct Compensation

The table below summarizes the target total direct compensation arrangements in place as at December 31, 2022 for the active NEOs, excluding the Interim CEO. Details on the compensation arrangements for the Interim CEO can be found under the heading “President and CEO Compensation – Interim President and CEO”.

Named Executive Officers	2022 Base Salary	CIP Target(1)     % of Base Salary	EIP Target(2)     % of Base Salary	2022 Target Total Direct     Compensation
Maarten Theunissen Interim CFO	$479,200 (3) ($395,200 + $84,000)	65%	130%	$1,413,640
Craig MacDougall EVP, Growth	$485,000	75%	150%	$1,576,250
Bruno Lemelin SVP, Operations & Projects	$485,000	65%	130%	$1,430,750
Oumar Toguyeni SVP, External Affairs and Sustainability	$406,000	65%	130%	$1,197,700

(1) CIP payouts range from 0% for below threshold performance to a maximum cap of 200% of target value, depending on the actual performance achieved.

(2) In the determination of actual individual EIP awards, the HRCC considers a series of key indicators to determine an EIP scoring factor between 80% and 120% of target value.

(3) For Mr. Theunissen, includes regular salary of $395,200 and a monthly stipend of $7,000 for service as interim CFO, assuming a full year of service in that capacity ($84,000).

Consistent with the Corporation’s pay-for-performance philosophy, the majority of target compensation is “at risk”, with an emphasis on long-term incentives.

2023 Management Proxy Circular IAMGOLD  |  34

COMPENSATION GOVERNANCE AND RISK MANAGEMENT

IAMGOLD’s compensation programs and practices were established to ensure strong alignment of pay with the long-term success of the organization. Key governance and risk mitigating features of the Corporation’s executive compensation program are outlined in the table below. Each year, the practices are reviewed against changing regulations and emerging best practices to ensure continued alignment with Shareholder interests.

IAMGOLD’s Governance Practices

✓  Compensation aligned with business strategy

•   Incentive compensation is tied directly to specific long-term objectives to advance corporate strategy

✓  Compensation aligned with the interests of Shareholders

•   Executive compensation is directly affected by share price and PSUs vest and pay out based on relative TSR and ROIC

•   Executive compensation programs incorporate measures tied to future success over various time horizons

•   Executives are required to meet share ownership guidelines

✓ Compensation is designed to attract, motivate, and retain high-calibre talent

•   Executive pay is benchmarked at market median (50th percentile) of our Peer Group for fully functioning incumbents for expected level of performance

✓  Compensation is performance-based

•   Most of the executive compensation is variable or ‘at risk’ and encourages high-performers to achieve exceptional levels of short and long-term performance through higher rewards; 75% for the former CEO and 66% or more for SVPs and EVPs

•   CIP and EIP awards are performance-based and earned, not guaranteed

•   Performance is assessed using a disciplined approach of pre-set measures with a pre-defined range of performance each year

✓  Compensation is aligned with risk management objectives

•   Compensation is aligned with the risk profile of the Corporation

•   CIP awards and multiplier for PSU awards are capped at 200% of target

•   Potential variable compensation is stress-tested regularly to avoid unintended behaviours or compensation outcomes

•   An annual compensation program risk assessment is conducted by an independent advisor

•   A clawback policy is maintained for both CIP and EIP granted and/or settled

✓  Compensation programs are well-governed

•   The Board considers all information and approves final performance results, and may exercise informed judgment as needed to ensure overall compensation outcomes match actual performance results and the Shareholder experience

•   Cross memberships on committees provide a link between the Committees’ respective oversights. The overlapping membership helps provide context of common activities that may impact multiple Committees and ultimately better manage risk. In addition, all Committees review CIP metrics and assessments related to their respective accountabilities

•   Incentive plan processes are well governed with annual reviews by internal audit

•   An independent advisor is retained to provide an external perspective on market changes and best practices related to compensation design, governance, and compensation risk management

•   An annual advisory vote is held on the Corporation’s approach to executive compensation

The compensation framework clearly prohibits:

×  Repricing or backdating of options

×  Hedging or monetizing of equity awards

×  Multi-year guarantees in employment agreements

×  Severance provisions of more than two years on termination following a change in control, and single trigger vesting of equity awards for those employed under executive agreements signed after November 2022

2023 Management Proxy Circular IAMGOLD  |  35

Risk Assessment

The HRCC and the Board regularly review and evaluate potential risks to the Corporation resulting from executive compensation based on an assessment framework that includes:

• Pay philosophy and practices;

• Design of the programs;

• Performance measurement; and

• Compensation governance.

In 2022, the HRCC engaged WTW to update the compensation program risk assessment. Based on this review, neither the HRCC nor the Board has identified any potential risks associated with the compensation policies or practices of the Corporation that would be reasonably likely to have a material adverse effect on the Corporation.

Clawback Policy

In 2009, the Corporation introduced a Forfeiture and Repayment condition on CIP and EIP awards for all executives. This ensures that incentive compensation may be lawfully recouped (or “clawed back”) in cases where the performance underlying such compensation is subsequently found not to be achieved, further enhancing the Corporation’s pay-for-performance compensation model.

In the event of any material restatement, correction or adjustment of the Corporation’s financial statements or operating results or other metrics upon which the CIP or EIP awards provided to the executive are based, the Corporation has the right to require repayment of any amounts paid that exceed what should properly have been payable, and/or to cancel or adjust any EIP granted and, in the case of unvested EIP, to adjust such accruals or rights as necessary to reflect the restated or adjusted results.

In addition, if the restatement or adjustment results from an act of fraud, misrepresentation, malfeasance, or gross negligence on the part of the executive, the executive will be liable if convicted of any crime involving fraud, willful misrepresentation, or gross negligence, to the Corporation for any damages suffered by the Corporation as a result of such wrongdoing. The executive may be further disciplined up to or including termination for cause.

It is anticipated that in 2023 new SEC clawback rules will come into effect. The Corporation will review the final regulations and make any changes necessary to ensure our continued compliance.

Anti-Hedging Policy

The Corporation prohibits officers and directors from engaging in hedging against a decrease in the market value of IAMGOLD’s equity securities.

Executive Share Ownership Guidelines

IAMGOLD has share ownership guidelines to further align executives with shareholders. The guidelines vary by executive level and are represented as a multiple of base salary. Share ownership includes the accumulation of common shares, as well as unvested restricted share units and performance share units. The ownership level is to be attained within three years of the later of joining the Corporation and appointment to the applicable executive level.

The executive share ownership guidelines are as follows:

Executive Position/Level	Share Ownership Target Effective in 2022 (multiple of base salary)
CEO	3.0
Executive Vice President	2.0
Senior Vice President	1.5

COMPENSATION PROGRAM OVERSIGHT

IAMGOLD has a strong foundation of good governance practices and oversight that strengthen risk mitigation and support our pay-for-performance philosophy.

Role of HRCC

The HRCC assists the Board in approving and monitoring IAMGOLD’s executive compensation practices, including the administration of the EIP.

The HRCC is comprised of at least three (3) directors, each of whom must be independent under applicable securities laws, policies, and stock exchange rules. In addition, in keeping with governance best practices, the HRCC consists of directors who are knowledgeable about issues related to human resources, talent management, compensation, governance and risk management.

As of the date of the Circular, the HRCC was composed of the following independent directors:

• Anne Marie Toutant (Chair)

• Christiane Bergevin

• Peter O’Hagan

• David Smith

Collectively, the members of the HRCC have experience in human resources and executive compensation by virtue of their extensive tenures as senior executives of publicly traded companies and/or members of boards and human resources/compensation committees of other public companies. For more details on the background of the HRCC members, see “Board of Directors”.

Compensation Decision Making Process

The annual compensation decision making cycle provides a rigorous process to ensure final compensation is fair and equitable.

Role of Management

The CEO provides the HRCC with recommendations for executives’ base salary adjustments, if any, CIP and EIP awards, that are ultimately approved by the Board. The CEO and the other executives are not involved in their own pay decisions and do not make recommendations on their own pay.

Compensation Consultant

The HRCC retains compensation consultants from time to time to provide expert and independent advice regarding compensation policies and decisions. Since 2011, the HRCC has retained WTW for executive compensation services. WTW’s executive compensation consultants report directly to the HRCC and are independent of management. The HRCC confirms WTW’s independence through an annual review of the factors set out by the Securities and Exchange Commission (“SEC”) that compensation committees should consider when selecting and monitoring the independence of their compensation advisors including the following criteria:

• WTW’s executive compensation consulting is separate and distinct from the team that assisted IAMGOLD with insurance products and services;

• Members of the WTW executive compensation consulting team are not involved in selling other WTW services to IAMGOLD and receive no incentive or other compensation based on the fees charged to IAMGOLD for such other services;

• WTW’s executive compensation consultants do not have a business or personal relationship with any of the HRCC members or management, and do not own any Common Shares (other than through portfolio investments such as mutual funds); and

• WTW has strict protocols and processes to mitigate conflicts of interest and all consultants are required to adhere to a code of conduct.

HRCC decisions and recommendations to the Board are its responsibility and reflect committee members’ views of the best interests of the Corporation, as informed by information and recommendations provided by compensation consultants.

2023 Management Proxy Circular IAMGOLD  |  39

In 2022, WTW provided support to the HRCC in reviewing meeting materials prepared by management and attending certain HRCC meetings. WTW reviewed the executive compensation and performance peer groups, conducted an update to the risk assessment review of the Corporation’s executive compensation plan, provided market compensation data for both executives and directors, provided advice and support in developing compensation arrangements for interim and incoming executive roles, reviewed the incentive compensation plans, advised on executive compensation trends and best practices, and reviewed executive compensation disclosure. The HRCC pre-approves non-compensation services that are provided to the Corporation by WTW in order to ensure that its independence from management is not compromised.

While in 2021, another team at WTW provided other consulting services directly to management related to the management of commercial and casualty insurance programs, no such services were provided in 2022.

	Executive Compensation	Other Fees	Total
2022	$295,373	$0	$295,373
2021	$128,607	$24,393(1)	$153,000

(1) In 2021, “Other Fees” do not relate to executive compensation and include $24,063 and $263 USD, which has been converted at 1.2546, the average monthly exchange rate for 2021.

COMPENSATION DECISIONS RELATED TO 2022 PERFORMANCE

2022 Total Direct Compensation Decisions

The following section provides a detailed discussion of the decisions made to determine each NEO’s total direct compensation for 2022.

Compensation for each executive is based on several factors, including individual performance, leadership, global responsibilities, experience, education, succession planning considerations, competitive pressures, and internal equity.

2023 Management Proxy Circular IAMGOLD  |  40

Base Salary

In early 2022, as part of the annual review process the following decisions were made related to the NEO’s base salaries. For a discussion of Ms. Bélanger’s compensation arrangements, see “President and CEO Compensation – Interim President and CEO”.

Named Executive Officers	2021	2022	% Increase
Maarten Theunissen VP Finance	$380,000	$395,200	4.0%
Interim CFO (1)	–	$479,200	–
Craig MacDougall EVP, Growth	$485,000	$485,000	0.0%
Bruno Lemelin SVP, Operations & Projects	$450,000	$485,000	7.8%
Oumar Toguyeni SVP, External Affairs and Sustainability	$395,000	$406,000	2.8%

(1) In addition to his salary as VP Finance, Mr. Theunissen received a $7,000 monthly stipend for serving as Interim CFO starting on September 16, 2022, an equivalent of $84,000 on an annual basis.

Cash Incentive Plan (CIP)

IAMGOLD is committed to its philosophy of pay-for-performance based on the fundamental premise that compensation should be directly correlated to the performance of the Corporation. To support this philosophy, CIP awards are used to reward executives for achievement of annual performance objectives. Performance criteria established by the HRCC will vary based on priorities for the year and can include a combination of financial, operational, strategic, growth and ESG metrics for a balanced view of performance.

The CIP assesses executives based on company performance results and individual results. For NEOs other than the CEO, the Company Scorecard results account for 70% and individual performance results account for 30% of the CIP award. For the former CEO, the weighting was 80% corporate and 20% individual.

While target levels of performance on CIP metrics are established as parameters, the Board can apply informed judgment to increase or decrease the CIP awards from the formula-based calculations to reflect the Corporation’s and the executive’s performance for that year as well as the HRCC’s long-term assessment thereof, recognizing that current year performance is influenced by multi-year activities.

2022 Company Scorecard and Results

The Corporation’s CIP key performance indicators are reviewed by the HRCC and stretch targets are established at the beginning of each year, in line with the Corporation’s budget and longer-term strategy. The Company Scorecard is aligned throughout the organization with weightings set depending on level within the organization.

The 2022 Company Scorecard captured performance in three categories: delivering on guidance, project advancement and financing, and environment, social and governance. As indicated in the table below, the

2023 Management Proxy Circular IAMGOLD  |  41

Company Scorecard reflects the importance of collaborative contribution towards the Côté Gold project advancement by assigning 50% of the total Company score to measures driving the successful completion of the project. A similar approach will be taken in 2023 while construction is being completed and preparations are made for first production in 2024.

2023 Management Proxy Circular IAMGOLD  |  42

In 2022, following the appointment of a new Executive Project Director at Côté Gold, a detailed project review and risk analysis was completed with an updated cost to complete, schedule and mine plan released on August 3, 2022. The Project Advancement measures on the 2022 Company Scorecard were finalized based on the updated Côté Gold project metrics.

CIP Company Scorecard and 2022 Performance
Deliver on Guidance 30%	Performance Measures: Consolidated Gold Production (10%), Total Cash Costs per ounce (10%), Capital Expenditures (10%) •   In 2022, the Corporation made a commitment to the shareholders that we would do what we say, and a large part of that commitment was delivering on our guidance. •   IAMGOLD reported attributable production of 713,000 ounces in 2022, above the upper end of our revised production guidance of 650,000 – 705,000 (revised upward on November 8, 2022) and exceeding our maximum target. This was driven by record operating performance at Essakane with continued management and mitigation of in-country supply chain constraints and security challenges, and a strong fourth quarter of production at Rosebel. •   Total Cash Costs were within our guidance range and outperformed target, benefiting from higher production and sales volumes, as well as continued operational improvements. This outperformance helped to offset certain operating and external cost escalation pressures experienced during the year. •   Capital expenditures at the operations were in line with company targets and company guidance, as IAMGOLD continues to invest into its assets according to the respective mine plans.
Project Advancement and Financing 50%	Performance Measures: Côté Gold Project Advancement (35%), Sufficient Funds to Complete Project Construction (15%) •   We assessed performance of Côté Gold Project Advancement based on measures related to capital expenditures, schedule variation and operational readiness tied to the updated project review completed in 2022. Capital expenditures and schedule variation targets are based on internal estimates associated with a P50 confidence level versus external guidance on a P80 schedule. Based on these metrics, capital expenditures are tracking well with significant contingency estimates remaining, while the project schedule was below target. Note that the Côté Gold project remains on track for the updated cost to complete and time to completion as outlined in the year end results reported on February 16, 2023. •   A key focus for 2022 was to secure the funds necessary to complete the Côté Gold project, as reflected by a 15% weighting of the Company Scorecard. Through the diligent work of our team, not only was the financing secured ahead of schedule, but values delivered, and quality of the plan completed far exceeded expectations. As such, the Board assessed performance at maximum.
Environment, Social, Governance 20%	Performance Measures: Environment Objectives (5%), Safety – Leading (5%), Safety – DART (5%), and Equity, Diversity & Inclusion (5%) •   Environment Objectives – Notwithstanding key achievements as it relates to the environment such as completing actions required to obtain a level A score for Towards Sustainable Management (TSM) Water management stewardship at Essakane and re-crafting site specific carbon reduction plans due to asset divestitures, we only achieved a threshold number of objectives (4 of 6) in the year. •   Safety (Leading Indicators) – Leading safety indicators are important to ensure a strong safety culture. This assessment is based on critical risk-based training for employees, safety meetings with employees & contractors and planned general inspection. Performance was assessed above target. •   Safety (DART) – While we had strong performance when looking at the DART metric, tragically an IAMGOLD employee lost his life in Burkina Faso in an off-site incident. Given this unfortunate event near Essakane, Management decreased the DART performance in the Company Scorecard (and Essakane site scorecard) to zero. •   Equity, Diversity & Inclusion – the KPIs are designed to progress towards the goal of an inclusive workplace with greater diversity for the benefit of the Corporation. In 2022 we conducted a full diagnostic of current state to establish benchmark comparisons, launched EDI awareness training for all leaders at sites, projects and corporate, and promoted a safe and supportive environment at work through “Mind, Body and Achievement” Phase 1 program.

Individual Performance

Individual performance for the executives is reviewed first by the CEO with feedback from the HRCC, taking into consideration the accomplishment of the functional goals established by the CEO and approved by the Board and an assessment of each executive’s performance in the areas of leadership, teamwork, innovation, general and administrative cost management, and other individual objectives for the year.

The CEO assesses each executive’s performance and recommends to the HRCC an individual performance score within 0% to 200%. The HRCC assesses the CEO’s individual performance on the same basis and makes a recommendation to the Board for their consideration and approval.

During 2022, the executive team worked collaboratively to support the advancement of the Côté Gold Project by focusing their efforts on achievement in their respective areas, creating the financial stability and operational focus necessary to complete the project.

The table below highlights key individual results that support the individual performance result for each applicable NEO. For a discussion related to Ms. Bélanger, see “President and CEO Compensation – Interim President and CEO”.

Equity Incentive Plan (EIP)

The EIP is designed to align executives with the shareholder experience by rewarding long-term sustained performance.

EIP Formula

The formula used to determine EIP awards is illustrated below:

  EIP Scoring Factor   The EIP grant is performance-based and dependent on both the Corporation’s and the executive’s performance. The EIP Scoring Factor can range from 80% to 120% of target.   The following factors are considered in arriving at the EIP Scoring Factor:   •  Key indicators of long-term performance   •  Shareholder experience   •  Management’s performance in the given economic climate and circumstances   •  Current Common Share price   •  Common Share ownership levels and total equity granted as a percentage of outstanding Common Shares of the Corporation  

2023 Management Proxy Circular IAMGOLD  |  47

Grant Allocation – EIP Vehicles Summary

The composition of the 2022 EIP awards to be granted in 2023 is set out below along with a summary of the features of each vehicle.

	PSUs	RSUs	Options
Grant Allocation	50%	25%	25%
Term	3 years	3 years	7 years
Description	Share units that vest conditionally based on pre-determined company performance criteria	Share units that are subject to time-vesting only	Right to acquire IAMGOLD shares at a specified price
Performance Criteria	75% TSR performance relative to S&P/TSX Global Gold Index	Not Applicable	Not Applicable
	25% Average ROIC
Vesting	Units cliff vest at the end of the term, and the number of units granted can vary from 0-200% of target depending on the performance conditions above	Units cliff vest at the end of the term	Options vest 20% per year over five years, starting on the first anniversary of the grant date
Payout	Settled in common shares at the end of the term	Settled in common shares at the end of the term	Participants acquire IAMGOLD shares at the exercise price defined as fair market value at the time of grant

As indicated in the table above, the vehicles have staggered and overlapping vesting schedules to ensure that executives continually focus on future value creation. The EIP awards are approved in the first quarter following the performance year, with actual grants made sometime following the determination of awards (e.g., the 2022 EIP was approved/awarded in Q1 2023 and will be granted later in 2023).

2023 Management Proxy Circular IAMGOLD  |  48

PSU Performance Measures

The PSU performance metrics used for the 2022 EIP were consistent with those used for 2021, measuring IAMGOLD’s total shareholder return (TSR) performance relative to the S&P/TSX Global Gold Index (relative TSR weighted 75%) and our capital efficiency relative to our three-year plan (ROIC weighted 25%).

In 2022, assisted by WTW, the HRCC reviewed the competitiveness and effectiveness of our long-term incentive plan relative to the Corporation’s peers. Based on that review, the HRCC adjusted the maximum payout for the PSU grant from 150% to 200% of target to improve the competitiveness of our plans where the Corporation achieves high levels of performance, consistent with the majority of our peers. In addition, the payout for a threshold level of performance for the ROIC metric was increased to 25% (from 0%) to provide consistency between the two metrics.

In conjunction with these changes, the level of performance required to achieve maximum vesting was increased from the 75^th to 85^th percentile for relative TSR, and from 7.5% to 8.5% for ROIC.

For ROIC, the HRCC was cognizant of the fact that the threshold and target performance levels (as outlined below) are lower than the 2021 award and also took into account the company’s cost of capital in determining the targets. However, the Board, in providing its approval, noted that it is essential to set realistic but challenging targets for the new management team from the baseline of IAMGOLD’s current position. The proposed target level represents outperformance of the current financial plan as a key step in the transition from our existing position to a strong and sustainable operational and financial position as we execute our strategy.

Metrics	Definition	2022 EIP (2023 – 2025) Performance Range (0%—200% vesting)
		Below Threshold (0%)	Threshold (25%)	Target (100%)	Maximum (200%)
Relative TSR 75% weight	TSR is measured based on the 3-year relative TSR compared to the S&P/TSX Global Gold Index, using the volume-weighted average share price for December at the beginning and end of the period (2023 – 2025). If the Corporation’s TSR outperforms the index but is negative, the metric score will be capped at 100% (target).	< 25th percentile	25th  (1) percentile	50th  (1) percentile	85th  (1) percentile
Average ROIC 25% weight	ROIC is calculated using a single three-year average (3-year average EBIT divided by the average invested capital) (3),(4).	< 3.1%	3.1% (2)	5% (2)	8.5% (2)

(1) For relative TSR, performance between the 25^th, 50^th and 85^th percentiles of the Index are calculated on a linear basis.

(2) For ROIC, 7% results in a payout of 150% and performance between 3.1% and 5%, 5% and 7%, and 7% and 8.5% is calculated on a linear basis.

(3) EBIT is calculated as net earnings adding back (i) financial costs, (ii) income tax expense, (iii) exploration expenses, and (iv) expenditures related to development projects that are not capitalized. Gains or losses from non-operating activities and other adjustments such as unrealized gains and losses on hedging and foreign exchange will be excluded. Non-cash impairment and net realizable value adjustments will be added back based on informed judgment.

(4) Invested capital is calculated as the sum of (i) property, plant and equipment, excluding construction in progress, (ii) long-term stockpiles, and (iii) current assets, excluding cash and cash equivalents, less current liabilities, excluding debt and deferred revenue. The average Invested Capital will be calculated over 13 quarters with the first quarter representing the opening balance.

Pay-for-Performance Alignment

A significant portion of the compensation of the Corporation’s NEOs is variable “at risk” pay, with an emphasis on equity-based compensation. This serves to align executives with shareholders.

The graph below highlights the target EIP grants, actual grants and the current realizable value of grants made from 2020 – 2022 (in respect of 2019 – 2021 performance) for a representative NEO. As illustrated, the equity grants in any given year can vary from target and the ultimate value realized will depend on our share price performance over the period.

Pay for Performance: 2020 to 2022

		2019 Granted March 2020	2020 Granted Feb. 2021	2021 Granted March 2022
Representative NEO	Target LTI Award Value	562,500	665,665	727,500
	Actual Equity Granted as a % of Target LTI Award	84%	77%	99%
	Actual Equity Granted ($ Value)	475,200	515,203	719,519
	Realized/Realizable LTI ($ Value)	343,530	315,770	462,898
	Realized/Realizable LTI as a % of Equity Granted	72%	61%	64%

(1) Realized / Realizable LTI value based on the December 30, 2022 share price of $3.47 and capturing the actual vesting of the 2019 PSU award (granted in 2020 and vesting in early 2023) of 37.5%. For 2020 and 2021 grants, PSU performance assumed to be target.

PRESIDENT AND CEO COMPENSATION

Interim President and CEO

On May 3, 2022, the Board Chair, Ms. Maryse Bélanger, stepped into the role of Interim President and CEO on a temporary basis. In recognition of the additional responsibilities and time commitment, the Board (excluding Ms. Bélanger) approved the following compensation arrangements:

• Salary of $75,000 per month (equivalent to $900,000 annually consistent with former CEO and former Interim CEO)

• DSU grant of $75,000 per month (granted on April 3, 2023)

During her time as Interim President and CEO, Ms. Bélanger is ineligible for the Board Chair cash retainer, but is eligible to receive the Board Chair DSU grant.

At the time of appointment, outside of the cash and equity retainers, there were no considerations for additional compensation as it was anticipated to be a short-term assignment. Following the completion of the year, to recognize the significant time commitment and Ms. Bélanger’s strategic leadership in driving the organization through its transformational journey over the 8-month period, the Board approved a recognition bonus of $1,275,000, which was paid in cash on March 23, 2023.

We are pleased to announce the appointment of Mr. Renaud Adams as the Corporation’s President and CEO effective April 1, 2023. Consequently, Ms. Bélanger reverted to her role as Independent Board Chair and on cessation of her Interim role received a DSU grant of $825,000 on April 3, 2023 related to the compensation arrangement discussed above, of which $600,000 was attributable to her time as Interim President and CEO in 2022.

Former President and CEO

Gordon Stothart served as the President and CEO of the Corporation from March 1, 2020 to January 11, 2022. The table below summarizes his compensation as President and CEO.

In prior years we illustrated the change in CEO and NEO total compensation in comparison to share price performance. Given the executive transitions during the year, this supplemental illustration is not as meaningful at present, so it has been excluded from this year’s disclosure. When comparing the trend in compensation to the trend in our share price performance, it is important to highlight that the largest component of our NEOs compensation is in the form of equity-based compensation and therefore closely aligned with the shareholder experience.

Value of Vested or Earned Awards during the Year

The table below shows the aggregate value of options and full value share-based units that vested during 2022. For the options, the value was determined based on the difference between the market price on the vesting date and the exercise price at the time of grant. For the full value share-based units, the value was determined by multiplying the number of units vested by the market value of the underlying Common Shares on the vesting date.

Named Executive Officers (1)	Option-based awards – Value     vested during the     year (1)	Share-based awards –      Value vested during the year (2)	Non-equity incentive      plan compensation –     Value earned during the year (3)

PENSION PLAN BENEFITS

Defined Contribution Plan

The Corporation has a defined contribution pension plan that is generally available to all Canadian salaried employees. Executives participate on an equal basis with salaried employees with respect to the terms, conditions, rights, and benefits under the plan. Notwithstanding any contribution made by an executive, each executive receives a contribution from the Corporation of at least 5% of base salary. In addition, for every contribution the executive makes, the Corporation contributes an additional 50% of the executive’s contribution, up to a maximum of 3%. The Corporation therefore contributes a total maximum of 8% of base salary subject to the income tax limit on deductible contributions. Contributions are deposited into investments designated by each individual executive. Ms. Bélanger does not participate in the defined contribution pension plan.

TERMINATION & CHANGE OF CONTROL BENEFITS

Termination & Change of Control Benefits

The table below summarizes the termination provisions as at December 31, 2022 under the following scenarios.

	Termination Without Cause	Termination Without Cause Following a CIC(1)	Retirement
Severance formula	MacDougall: 24 months Lemelin and Toguyeni: 18 months Salary + Bonus (prior two-year average)	MacDougall and Toguyeni: 24 months Lemelin: 18 months Salary + Bonus (prior two-year average)	Not Applicable
Mitigation	Payments cease 12 months after termination upon obtainment of new employment	-	Not Applicable
CIP in year	-	-	Prorated to retirement date
PSUs (2)	Unvested forfeited	Vest immediately	Continued vesting per original schedule
RSUs (2)	Unvested forfeited	Vest immediately
Stock Options (2)	Unvested forfeited Vested remain exercisable for 60 days subject to original expiry	Vest immediately and exercisable for 60 days
Benefits	Continue through severance period subject to terms of benefit plan

(1) A “change of control” occurs where 40% or more of the votes attached to the securities of the Corporation are acquired and such votes are exercised to elect a majority of directors of the Corporation who were not directors immediately prior to the acquisition of such securities. For greater clarity, the severance is not payable upon a mere change of control and is only payable if, within 12 months of the change of control, and NEO’s employment was terminated without cause, or the NEO was constructively dismissed.

(2) While severance is based on a double trigger, For Mr. MacDougall, Mr. Lemelin and Mr. Toguyeni equity awards vest immediately upon a change in control. New executive agreements require a double trigger for equity awards to vest (i.e., change in control and termination of employment)

As at December 31, 2022, Ms. Bélanger did not have an agreement with the Corporation that would call for payments under a termination without cause or a termination without cause following a change of control.

According to the agreement in place when Mr. Theunissen assumed the VP Finance role, upon a termination without cause he would be eligible to receive the greater of six months payment of salary in lieu of notice or common law notice or payment in lieu in the Province of Ontario, with the obligation to mitigate. He is eligible to continue to receive health and / or dental group benefits through the notice period.

During 2022, the HRCC reviewed the standard form executive agreement and updated such that all new executive agreements require a double trigger for equity awards to vest (i.e., change in control and termination of employment).

As per his employment agreement, Mr. Stothart was entitled to the continuation of his base salary for 24 months (subject to mitigation obligations in the second half of the severance period). Mr.Stothart was also entitled to a one-time payment of $1,500,000 as a lump sum for short-term incentive compensation, delivered within 15 days within the end of his employment. In addition, certain benefits are continued through the severance period. All unvested share options, RSUs, and PSUs continued to vest in accordance with their normal schedules.

DIRECTOR COMPENSATION

IAMGOLD directors’ compensation program aims to appropriately compensate the Corporation’s directors while aligning director compensation with the advancement of stakeholder interests. The HRCC, as part of its mandate, and the Board, consider director remuneration, in both structure and amount, relative to that of the Corporation’s Peer Group (consistent with those used to benchmark executive compensation) and the nature and extent of the responsibilities, risks and time commitment associated with a directorship of a large, publicly traded, inter-listed corporation.

The Board recognizes that the compensation for directors must not compromise their independence and ability to make appropriate judgments, including overseeing the compensation paid to management. As such, it does not consist of equity-based compensation that is performance driven or otherwise risks aligning directors’ interests away from those of Shareholders and toward those of management.

Director compensation is comprised of an annual cash retainer and equity retainer, in the form of share units. Directors can elect at the time of grant to defer the issue of the share units until retirement from the Board. All but one of the directors elected to receive the equity retainer in DSUs. No attendance fee for a Board or Board Committee meeting is paid to directors. Directors do not receive options and the Corporation does not provide any loans to directors.

2022 DIRECTORS’ COMPENSATION SUMMARY

	Cash	Equity
Annual Retainer – Chair (1)	$225,000	$100,000
Annual Retainer – Other Board Members	$110,000	$93,100
Additional Retainer - Lead Independent Director (2)	$25,000	N/A
Additional Retainer – Chair of Audit and Finance Committee (“AFC”), HRCC and Sustainability Committee (“SC”) (3)	$25,000	N/A
Additional Retainer – Chair of the NCGC and Technical Committee (3)	$15,000	N/A
Additional Retainer – Chair and Members of the Côté Project Review Committee (“CPRC”) (4)	$25,000	N/A
Fee when travel to attend a Board or Board Committee meeting exceeds four hours	$1,750	N/A

(1) As a result of her service as Interim CEO effective May 3, 2022, Ms. Belanger did not receive a cash retainer for her service as a director after that date.

(2) In connection with Ms. Bélanger’s appointment as Interim President and CEO, the Board appointed Mr. Smith as Lead Independent Director and awarded him an additional annual cash retainer of $25,000.

(3) In recognition of the additional responsibilities, complexities, and time commitment for chairing a Board committee, the Chair of each of the Audit and Finance, Human Resources and Compensation, and Sustainability Committees received an additional cash annual retainer of $25,000 and the Chair of each of the Nominating and Corporate Governance and Technical Committees received an additional annual cash retainer of $15,000.

(4) In recognition of the time commitment and strategic importance of the Côté Project, the Chair and each member of the ad hoc Côté Project Review Committee also received an additional annual cash retainer of $25,000.

In 2022 the Board put in an extraordinary effort to fundamentally improve the trajectory of the Corporation in challenging circumstances, increasing the accountability of the Board during this time. During the year the Corporation held 28 Board meetings and individual directors as of December 31, 2022 attended on average approximately 40 Board and Board Committee meetings in total during the year. However, as indicated above, board members do not receive attendance fees to recognize this additional workload. As a result, in recognition of the exceptional workload and commitment, a special one-time equity grant of $50,000, was awarded to board members on December 22, 2022.

2022 Review of Director Compensation – 2023 Compensation Arrangements

In conjunction with the Board renewal, the HRCC and NCGC, with the assistance of WTW, the HRCC’s independent compensation consultant, reviewed the Corporation’s director compensation versus the compensation arrangements for the companies included in the Peer Group used to benchmark executive compensation. That review noted that director compensation was below the 25^th percentile of the Peer Group. Given this information and recognizing that director retainers had not been increased for seven (7) years, it was determined that overall director compensation should be increased to be market competitive, and that the increase should be in the form of equity grants to increase the alignment with the interests of shareholders to the extent possible. The following changes were approved following the review:

• Increased Board Chair annual retainer to $360,000 with cash retainer of $210,000 and equity retainer of $150,000, the maximum allowed under the Share Incentive Plan

• Increased Board member annual retainer to $240,000, with cash retainer of $110,000 (no change) and equity retainer of $130,000

• Increased additional Independent Lead Director annual retainer to $40,000

• Eliminated travel fee of $1,750 that had previously been paid when travel time exceeded four (4) hours to attend Board or Board Committee meetings

• Increased share ownership guidelines to a multiple of four (4) times cash retainer ($840,000 for Board Chair and $440,000 for other board members)

For each director other than the Board Chair, in 2021 the equity retainer was $70,000 per year. However, as result of a change in the timing of grants under the regime, an additional $23,100 was awarded to directors in 2022. Following the conclusions of the 2022 review of director compensation, it was determined that the DSUs granted and vested in 2022 of $93,100 (with grant date value of $83,911) will serve as a transition year, with the revised equity retainer amount of $130,000 coming into effect as of January 1, 2023 and being granted quarterly in arrears at the end of March, June, September and December with full vesting at the end of the year. DSUs granted to directors as part of their equity retainer are to be priced based on the 30-day volume-weighted average trading price of the Common Shares on the TSX as of the applicable grant date.

The graph below illustrates the historical annual retainers for board members, along with the 2023 compensation arrangements.

(1) The number of awarded units is calculated using the volume-weighted average closing price for the 30 trading-dates preceding the grant date. The grant value of the share-based awards was calculated by multiplying the number of units by the closing market Common Share price of the TSX on the date of grant. Due to a blackout from May to August, the May 2022 grant was not awarded until August 5, 2022. The value on that date was less than the price used to determine the number of awarded units. The table above reflects the value when the units were awarded ($60,335 v. $70,000)

DIRECTOR SHARE OWNERSHIP GUIDELINES

With a view to further aligning director and Shareholder interests, as mentioned above, the Board approved updated director share ownership guidelines in connection with its overall review of director compensation. The updated director share ownership guideline is a number of Common Shares equal in value to four (4) times the cash retainer paid to directors (resulting in $840,000 for the Board Chair and $440,000 for all other directors), to be achieved by each director within five (5) years of the date of appointment to the Board.

The former director share ownership guideline required directors to acquire an amount of Common Shares equal to $600,000 for the Board Chair and $300,000 for all other directors, to be achieved within five (5) years of the date of appointment to the Board.

As result of the increased share ownership requirements approved by the Board on February 16, 2023, all directors serving at the time of the increase will have one additional year to acquire their applicable amount of Common Shares. While none of the members have met their requirements as of the date of this Circular, they are all currently within the grace period to achieve the required ownership level. See also “Board of Directors”.

Given the volatility of the equity markets and that fluctuations in the market value of the Corporation’s share price are not within the control of directors, the Board has prescribed that, once a director has met the share ownership

2023 Management Proxy Circular IAMGOLD  |  65

requirement, there is no requirement for the director to purchase additional Common Shares should the value of the director’s holdings fall below the requirement. The higher of the purchase price or market value of Common Shares acquired is used to determine whether a director has achieved the share ownership requirement.

SHARE INCENTIVE PLAN

The Share Incentive Plan consists of the Share Purchase Plan, the Share Bonus Plan, the Share Unit Plan (formerly the Deferred Share Plan) and the Share Option Plan. The Share Incentive Plan was established for the benefit of full-time and part-time employees, directors and officers of the Corporation and designated affiliates as well as persons or companies (or an employee of such person or company) engaged to provide ongoing management, consulting services or other services to the Corporation or any designated affiliate. Each of the foregoing is an eligible participant under each of the four plans with the exception that non-employee directors of the Corporation are not eligible to participate in the Share Purchase Plan (the relevant participants referred to below as “Participants”).

Set out below is a summary of certain provisions of the Share Incentive Plan, which summary is qualified in its entirety by the provisions of the Share Incentive Plan. A copy of the Share Incentive Plan is available to any shareholder, without charge, upon request to the Secretary of the Corporation.

Capitalized terms used in this summary of the Share Incentive Plan have the meanings ascribed to them in the Share Incentive Plan. The information set out below, is presented as at December 31, 2022.

SHARE INCENTIVE PLAN MAXIMUM

The following table sets out the maximum number of Common Shares reserved for issuance under each of the four plans comprising the Share Incentive Plan, the number of Common Shares issuable under outstanding awards, and the number of remaining Common Shares available to be issued pursuant to future awards under each plan, together with, in each case, the percentage of the issued and outstanding Common Shares as at December 31, 2022 that this figure represents.

Share Incentive Plan	Common Shares Reserved for Issuance	Outstanding Common Shares Awarded	Remaining Common Shares Available for Grant
Share Purchase Plan, Share Bonus Plan, and Share Unit Plan (1)	13,008,453 (2.7%)	6,309,298 (1.3%)	6,699,155 (1.4%)

(1) In 2014, the Share Incentive Plan was amended to establish two separate pools which respectively establish a maximum number of Common Shares which are available for issue from treasury (i) among the Share Unit Plan (formerly the Deferred Share Plan), the Share Purchase Plan and the Share Bonus Plan (awards under these plans are also known as “full value awards”), and (ii) under the Share Option Plan (awards under this Plans are also known as “option awards”). Accordingly, the information in the above table is divided between these two separate pools rather than by individual plan.

ANNUAL BURN RATE

The annual burn rate of the Share Incentive Plan, calculated in accordance with the TSX Company Manual, for each of the three most recently completed financial years of the Corporation is set out in the table below. In accordance with the rules of the TSX, the annual burn rate is expressed as a percentage and is calculated by dividing the number of securities granted under the arrangement during the applicable financial year by the weighted average number of securities outstanding for the applicable financial year (calculated in accordance with the CPA Canada Handbook).

	2022 Burn Rate	2021 Burn Rate	2020 Burn Rate

Share Purchase Plan	–	–	–

(1) There have been no issuances during the fiscal year for these plans.

INSIDER LIMITATIONS

The Share Incentive Plan provides that in no event shall any security-based compensation arrangement (within the meaning of the rules of the TSX), together with all other previously established and proposed security-based compensation arrangements of the Corporation, result in:

i. the number of Common Shares issuable from treasury at any time pursuant to options granted to insiders exceeding 10% of the issued and outstanding Common Shares; or

ii. the issue from treasury to insiders, within any one-year period, of a number of Common Shares which exceed 10% of the issued and outstanding Common Shares.

2023 Management Proxy Circular IAMGOLD  |  68

In addition, the number of Common Shares reserved for issue to non-Executive directors under the Share Incentive Plan shall not exceed (x) for all non-Executive directors, in the aggregate, a maximum of 1% of the number of outstanding Common Shares, and (y) on an individual non- Executive director basis, awards of Common Shares and/or options per non-employee director in any one calendar year having a maximum aggregate value of $150,000 at the time of the awards.

SHARE PURCHASE PLAN

Subject to the requirements of the Share Purchase Plan, the Board has the authority to select those Participants (which excludes non-Executive directors) who may participate in the Share Purchase Plan. Under the Share Purchase Plan, the Corporation may choose to issue Common Shares from treasury or to deliver Common Shares purchased through the facilities of the TSX to satisfy the obligation of the Corporation to deliver Common Shares to Participants pursuant to the Share Purchase Plan. At such times or times as are determined by the Corporation, but in any event no later than December 31 in the applicable calendar year, the Corporation will credit each Participant with the applicable contribution of the Corporation.

In order to satisfy the obligations of the Corporation under the Share Purchase Plan, the Corporation may either (i) issue from treasury for the account of each participant Common Shares equal in value to the aggregate amount contributed to the Share Purchase Plan by such Participant and the Corporation and held in trust as of such date at the applicable price determined in accordance with the provisions of the Share Purchase Plan (being the weighted average price of the Common Shares on the TSX for the period in respect of which Common Shares are being issued from treasury under the Share Purchase Plan, being the period of time during which the aggregate contribution of the Participant being used to purchase such Common Shares has been accumulated and which, therefore, could result in issuances at less than the market price of the Common Shares as determined in accordance with the TSX Company Manual) or (ii) deliver to the account of each Participant in the Share Purchase Plan, Common Shares equal in number to the number of Common Shares purchased through the facilities of the TSX with the aggregate amount contributed to the Share Purchase Plan by the Participant and the Corporation as of such date. The Corporation will only issue whole Common Shares.

The minimum contribution of a Participant in the Share Purchase Plan is one per cent, and the maximum contribution is ten percent, of such Participant’s basic annual remuneration. The matching contribution of the Corporation is 75% of the Participant’s contribution until the Participant’s contribution reaches 5% of such Participant’s basic annual remuneration. As a result, the Corporation’s maximum contribution will be 3.75% of a Participant’s basic annual remuneration.

Under the Share Purchase Plan, unless otherwise determined by the HRCC, if a Participant ceases to be employed by, or provide services to, the Corporation and all designated affiliates for any reason (including disability or death) or receives notice from the Corporation of the termination of his or her contract of service or employment, (i) the Participant shall automatically cease to be entitled to participate in the Share Purchase Plan, (ii) any portion of the contribution of the Participant then held in trust for the Participant shall be paid to the Participant or the estate of the Participant, (iii) any portion of the contribution of the Corporation then held in trust for the Participant shall be paid to the Participant or the estate of the Participant, except in the case of a resignation (not as a result of retirement) or termination for cause and, in such cases, any portion of the contribution of the Corporation then held in trust for the Participant shall be returned and paid to the Corporation, and (iv) any Common Shares then held in safekeeping for the Participant shall be delivered to the Participant or the estate of the Participant.

Common Shares issued for or delivered to the account of a Participant in the Share Purchase Plan will be held in safekeeping and delivered, subject as otherwise provided in the Share Purchase Plan, to the Participant at such time or times as are determined by the Corporation upon the request of the Participant. If there is a take-over bid (within the meaning of the Securities Act) made for the Common Shares, then the HRCC may make any Common

2023 Management Proxy Circular IAMGOLD  |  69

Shares held in safekeeping under the Share Purchase Plan for a Participant immediately deliverable in order to permit such Common Shares to be tendered to such bid. In addition, the HRCC may permit the contribution of the Corporation to be made and Common Shares to be delivered for the then aggregate contribution of the Participant and the Corporation prior to the expiry of any such take-over bid in order to permit such Common Shares to be tendered to such bid.

SHARE BONUS PLAN

The Share Bonus Plan permits Common Shares to be issued as a discretionary bonus to eligible Participants by the HRCC in its sole and absolute discretion and for no consideration.

SHARE UNIT PLAN

The Share Unit Plan (formerly the Deferred Share Plan) permits the HRCC to grant awards of share units to Participants. Under the Share Unit Plan, share units awarded to a Participant may either be (i) issued from treasury, or (ii) purchased through the facilities of the TSX, and delivered to such Participant. The provisions and restrictions (including any vesting provisions) attached to awards of share units granted under the Share Unit Plan will be determined by the HRCC at the time of grant of the award of share units.

If there is a take-over bid (within the meaning of the Securities Act) made for outstanding Common Shares, the HRCC may accelerate any awards granted under the Share Unit Plan and issue or deliver any Common Shares issuable or deliverable under the Share Unit Plan for the sole purpose of permitting such Common Shares to be tendered to such bid.

Subject to any employment agreement or notice or agreement with respect to an award granted under the Share Unit Plan or as otherwise determined by the HRCC, if a Participant ceases to be employed by or provide services to the Corporation and all designated affiliates or resigns as a director or officer of the Corporation and its designated affiliates for any reason other than retirement, disability or death, the Participant shall automatically cease to be entitled to participate in the Share Unit Plan and any entitlement to receive share units thereafter under the Share Unit Plan shall terminate.

If a Participant dies, any share units to which such Participant was entitled in respect of an award granted under the Share Unit Plan as of the date of death will be delivered as soon as practicable thereafter and, subject to any employment agreement or notice or agreement with respect to an award granted under the Share Unit Plan or otherwise determined by the HRCC, such Participant shall cease to be entitled to participate in the Share Unit Plan and any entitlement to receive any share units under the Share Unit Plan will terminate with effect as of the date of death of such Participant.

SHARE OPTION PLAN

The Share Option Plan provides for the grant of non-transferable options for the purchase of Common Shares to Participants. Subject to the terms of the Share Option Plan, the Board has the authority to select Participants to whom options will be granted, the number of Common Shares subject to options granted and the exercise price of Common Shares under option.

Subject to the provisions of the Share Option Plan, no option may be exercised unless the optionee at the time of exercise is:

1. In the case of an eligible employee, an officer of the Corporation or a designated affiliate or in the employment of the Corporation or a designated affiliate and has been continuously an officer or so employed since the date of grant of the option, provided, however, that a pre-approved leave of absence will not be considered an interruption of employment for the purposes of the Share Option Plan; and

2023 Management Proxy Circular IAMGOLD  |  70

2. In the case of any other Participant, engaged, directly or indirectly, in providing ongoing management or consulting services for the Corporation or Designated Affiliate and has been so engaged since the option’s date of grant.

The exercise price for purchasing Common Shares is determined by the HRCC and cannot be less than the closing price of the Common Shares on the TSX on the last trading day immediately preceding the date of grant of the option. Each option, unless sooner terminated pursuant to the provisions of the Share Option Plan, will expire on a date determined by the Board at the time of grant, which date cannot exceed seven years from the date the option was granted.

The vesting provisions of options granted pursuant to the Share Option Plan are determined by the Board and provide for the vesting of options in accordance with any applicable terms of any employment agreements or in any notice or option agreement entered into between the Corporation and the holder of the option. The aggregate number of Common Shares at any time available for issue to any one person upon the exercise of options cannot exceed five per cent of the number of Common Shares then outstanding. If options granted under the Share Option Plan are surrendered, terminate or expire without being exercised on whole or in part, new options may be granted covering the Common Shares not purchased under such lapsed options.

If a Participant: (i) ceases to be a director of the Corporation or a designated affiliate (and is not or does not continue to be an employee thereof) for any reason (other than death), or (ii) ceases to be employed by, or provide services to, the Corporation or a designated affiliate, or any corporation engaged to provide services to the Corporation or the designated affiliates, for any reason (other than death) or receives notice from the Corporation or a designated affiliate of the termination of his or her employment contract, except as otherwise provided in any employment contract or the terms of the option, such Participant will have 60 days from the date of such termination or cessation, as the case may be, to exercise his or her options to the extent that such Participant was entitled to exercise such options at the date of such termination or cessation. Notwithstanding the foregoing or any employment contract, in no event will such right extend beyond the term of the option. If a Participant shall die, any option held by such Participant at the date of such death shall become immediately exercisable, and shall be exercisable in whole or in part only by the person or persons to whom the rights of the optionee under the option shall pass by the will of the optionee or the laws of descent and distribution for a period of nine months (or such other period of time as is otherwise provided in an employment contract or the terms and conditions of any Option) after the date of death of the optionee or prior to the expiration of the option period in respect of the option, whichever is sooner, and then only to the extent that such optionee was entitled to exercise the option at the date of the death of such optionee.

If a take-over bid (within the meaning of the Securities Act) is made for the Common Shares, then the Board may permit all outstanding options to become immediately exercisable in order to permit Common Shares issuable under such options to be tendered to such bid.

BLACKOUT PERIODS

The nature of the business of the Corporation gives rise to a number of periods each year during which directors, officers and employees are precluded from trading in securities of the Corporation in accordance with the trading policy and guidelines of the Corporation. These periods are referred to as “blackout periods”. Pursuant to the terms of the Share Incentive Plan, there is an automatic extension of an option term that would otherwise have expired during, or within ten business days of, a Corporation imposed blackout period. In such circumstances, the end of the term of such option will be the tenth business day after the end of the blackout period.

2023 Management Proxy Circular IAMGOLD  |  71

ASSIGNABILITY

No rights under the Share Incentive Plan and no option awarded pursuant to the provisions of the Share Incentive Plan are assignable or transferable by any Participant other than pursuant to a will or by the laws of descent and distribution.

AMENDING PROVISIONS

The Board may, without Shareholder approval, make the following amendments to the Share Incentive Plan:

• Any amendment which would change the number of days set out in section 4.13 of the Share Incentive Plan with respect to the extension of the expiration date of options expiring during or immediately following a blackout period,

STATEMENT OF CORPORATE GOVERNANCE PRACTICES

The Board is committed to maintaining a high standard of corporate governance and believes that doing so is an important component of the successful operation of the business, the preservation of IAMGOLD’s reputation, and the creation and protection of stakeholder value, all of which are in the long-term best interests of the Corporation.

The NCGC oversees, among other things, IAMGOLD’s continued compliance with the corporate governance requirements of applicable regulatory authorities and monitors evolving corporate governance practices, including those suggested by shareholder advocates and institutional proxy advisors. In addition to regulatory requirements, the Corporation considers and adopts other corporate governance practices which are appropriate for the business of the Corporation and consistent with best practices.

IAMGOLD is listed on the TSX and the NYSE and complies with the corporate governance and other requirements of such stock exchanges and all other applicable Canadian and United States securities regulatory authorities. The Corporation is a “foreign private issuer” for purposes of the securities regulatory requirements of the United States.

KEY GOVERNANCE ATTRIBUTES

As discussed further in this Statement of Corporate Governance Practices and elsewhere in this Circular, the Corporation has the following effective governance structures and attributes:

Board independence: All members of the Board are independent, other than Mr. Adams, who serves as President and CEO of the Corporation. All standing committees of the Board are comprised 100% of independent directors.

Advance notice: The Corporation has an advance notice by-law that requires adequate notice be given by any Shareholder seeking to nominate directors for election to the Board and adequate disclosure of information with respect to any such director nominees, as would be provided in a management information circular so that all Shareholders can make an informed vote with respect to any director nominee.

Share ownership requirements: The Corporation requires directors and executives to own Common Shares to reinforce their commitment and to align with shareholders’ interests and set minimum requirements for members of the Corporation’s executive leadership team.

Diversity policy: The Corporation has adopted a formal diversity policy for the Board and management that includes a commitment to (i) a minimum target of the greater of (x) two (2) female directors or (y) a Board comprised of 30% female directors, and (ii) a target of 20% female representation among executives by 2030. Following the Meeting, the Board is expected to include three (3) women, or ~38% of all directors. As of the date hereof, 12% of executives are female.

Committee mandates and position descriptions: The Board has adopted formal mandates for each of its committees, as well as position descriptions for each of the Board Chair, committee chairs, and the CEO role.

Board and management succession: The Board closely monitors the Corporation’s succession planning for directors, the CEO, and senior executives, and the Corporation maintains a director and executive succession planning process to develop and maintain a deep pool of talent within the Corporation to ensure continued effective management.

Board renewal: The Board has adopted a renewal policy which recommends the average tenure of the Board not exceed ten (10) years, the tenure of the Board Chair or the chairs of any committee not exceed ten (10) consecutive years.

2023 Management Proxy Circular IAMGOLD  |  74

Formal assessments: On an annual basis, the Board, through the NCGC, conducts a formal assessment of its effectiveness as a whole and of its committees, as well as the contribution of individual directors. The Board also assesses the performance of the CEO and, with the advice of the CEO, other members of the ELT.

Code of conduct: To make clear its commitment to conduct business in accordance with all applicable laws, rules and regulations, and high ethical standards, the Corporation’s Code of Business Conduct and Ethics applies to members of the Board, employees, contractors and representatives in every business where IAMGOLD operates globally.

Compensation claw back: The Corporation maintains a policy to “claw back” compensation where the results for which it was granted are subsequently found not to be confirmed, such as in cases of material earnings restatements or fraud.

Compensation policies: Executive employment agreements use market-based compensation structures – executives do not receive multi-year guarantees of salary increases, bonuses or equity-related compensation, irrespective of performance.

Related party transactions: The Audit and Finance Committee is responsible for reviewing and evaluating all related party transactions. The Corporation did not enter into any related party transactions in 2022.

Shareholder engagement: The Board values open dialogue and an exchange of ideas with shareholders and has adopted a Shareholder Engagement Policy in order to outline how the Board, management and shareholders can communicate and engage on matters of importance.

No dual class shares: The Corporation does not have a dual class share structure or any non-voting shares. The only issued and outstanding equity securities of the Corporation are the Common Shares, which carry one vote per share and rank equal in all other privileges.

No interlocks: No interlocks between either directors or directors and executives on other boards of directors.

Chair vote: The Board Chair does not have an additional, tie-breaking vote in the event that directors’ votes are evenly split on a particular matter.

No hedging: The Corporation has established a policy that prohibits executive officers and directors from hedging against any decrease in the value of the Common Shares, to ensure continued alignment of the interests of management and the Board with the interests of Shareholders.

NOMINATION OF DIRECTORS

The Board delegates responsibility to the NCGC for developing a process for identifying director nominees who will best serve the needs of the Corporation and making recommendations to the Board with respect thereto. The NCGC is comprised entirely of independent directors. In making recommendations regarding nominees, the NCGC considers among other things:

• the mix of skills, competencies and experience required in light of IAMGOLD’s strategy, principal risks, and operational, organizational and financial requirements;

• the independence of each director and the Board as a whole;

• the performance of incumbent directors;

• the diversity of the Board;

• other mining and public company directorships;

2023 Management Proxy Circular IAMGOLD  |  75

• the time commitment required of a director; and

• an appropriate board size to facilitate effective decision-making.

NCGC Process for Identifying and Evaluating Director Candidates

	Assessment	NCGC assesses skills and characteristics of Board members in context of business strategy
	Analysis	NCGC conducts analysis to determine current and future gaps and needs in Board composition

	Selection	Board evaluates and selects nominees to the Board.

The NCGC is authorized to engage professional search firms at the Corporation’s expense to assist with the identification, evaluation and due diligence on potential nominees for Board vacancies. In 2022, the Corporation conducted a competitive tender process in order to retain a professional third-party search firm to assist with identifying potential nominees to the Board and performing appropriate due diligence on such candidates.

2023 Management Proxy Circular IAMGOLD  |  76

BOARD SKILLS

In recommending suitable nominees for election to the Board, the NCGC, primarily, seeks candidates that have previous senior executive experience, either as chief executive officers, chief financial officers, chief operating officers, or other members of the C-suite, in mining or other industry sectors. In addition to senior executive, leadership experience in mining or other industries, in making its recommendation of director nominee, the NCGC considered competencies, skills and experience in the following specific areas (the following comprise the Board skills matrix):

DIVERSITY, INCLUSION AND TENURE

Board of Directors

IAMGOLD seeks to maintain a Board comprised of talented and dedicated directors with a diverse mix of experience, skills and backgrounds collectively reflecting the strategic needs of the business and the nature of the environment in which IAMGOLD operates. When assessing the composition of the Board, the principal focus is on ensuring that members collectively possess the experiences, skills and backgrounds needed to effectively oversee the business of IAMGOLD, as well as varied personal experience and characteristics. The Board’s membership has been substantially refreshed in recent years, with all directors nominated for election at the

2023 Management Proxy Circular IAMGOLD  |  78

Meeting having joined the Board in the time since September 2021, and currently includes a diversity of skills and experience in the areas referenced above in the Board skills matrix.

Consistent with its view on diversity and with respect to the representation of women on the Board, the Corporation has adopted the Diversity Policy, pursuant to which it has set a minimum target of the greater of: (i) two (2) female directors; and (ii) a Board comprised of 30% female directors. Following the meeting, the Board is expected to include three (3) female directors, or ~38% of all directors, and seven (7) of eight (8) directors will be independent, or ~88% of all directors.

Expected Board composition following the Meeting:
A Board comprised of eight (8) directors	Three (3) female directors (~38%)	Seven (7) independent directors (~88%)	Two (2) female directors serving in a position of Board leadership– the Board Chair and the chair of the Sustainability Committee

The Board believes that director nominations and executive appointments should be made, and should be perceived as being made, on the objective merits of the candidates, which would include diversity among the factors taken into consideration, and having fixed targets could impede the application of this principle. The NCGC considers, among other types of diversity, the level of representation of women, Aboriginal peoples, persons with disabilities, and members of visible minorities (collectively, the “Designated Groups”) on the Board when determining director nominees. Where Board renewal or expansion of the Board is being considered, the NCGC emphasizes the identification of qualified candidates that will enhance the Board’s effectiveness through diversity, and prioritizes their selection within the context of the knowledge, skills and experiences the Board requires. Through the Diversity Policy, the Corporation has established a framework that will enable the evolution of a diverse Board, executive management, and corporate organization generally, as a more sustainable approach to improving diversity. Following the meeting, it is expected that there will be three (3) persons from Designated Groups serving on the Board, being the three (3) female directors.

Each director and director nominee presented for election at the Meeting is highly qualified to serve as a director of the Corporation. Each has demonstrated their merit through the knowledge, skills, and experience they bring to the Board and their ongoing performance in service to the Corporation.

Executive Management

The Board also recognizes the benefits of a diversity of views among executive management, which has direct responsibility for the day-to-day management of the Corporation. On at least an annual basis, the CEO, with the assistance of the SVP, People, assesses the diversity of the Corporation’s workforce and leadership structure and the Corporation has adopted a gender representation target of having 20% women by not later than 2030. Currently, among the 25 executive management positions at IAMGOLD, including among its major subsidiaries, three (3) positions (12%) are held by women, and three (3) positions (12%) are held by a member of a visible minority. While merit, qualifications and performance are fundamental considerations in recruitment and appointment, the Board considers, among other types of diversity, the level of representation of Designated Groups, together with the level of overall diversity in the Corporation, when making or approving executive management and other appointments. Other than the gender representation targets described above, the Corporation does not have a target for the aggregate number of members of Designated Groups among members of executive management. (See “Board of Directors” above for additional information).

  The Corporation has a total of 25 executive
management positions, including among
major subsidiaries   Three (3) executive management
positions are held by women

IAMGOLD Diversity

The Corporation strives to be a diverse, equitable and inclusive workplace where its employees at all of its operations feel empowered to bring their full, authentic selves to work, and it seeks to do business with partners who share these values. The Corporation’s equity, diversity and inclusion (“EDI”) Steering Committee, led by executive leaders, provides strategic direction for this initiative within the organization to help maintain focus and to drive positive results for IAMGOLD while creating more opportunities.

In 2022, IAMGOLD engaged in several initiatives to advance EDI imperatives, aligned to corporate values, and in response to results from an EDI diagnostic completed in the previous year. EDI awareness workshops were implemented for all leaders globally, specifically focused on the topic of Conscious Inclusion, building awareness surrounding IAMGOLD’s role in creating a more inclusive work environment. Additionally, a strategy to promote a safe and supportive workplace free of physical and psychological hazards was developed and deployed in close partnership with Health & Safety. This included an updated Health & Safety policy to include both physical and psychological safety elements, as well as the development of learning modules for employees globally on the topic of psychological safety.

As a Canadian business committed to responding to the Truth and Reconciliation Commission of Canada’s Calls to Action, the Corporation continues to take meaningful action towards reconciliation by fostering long-term, mutually beneficial relationships with our Indigenous partners and offering our employees opportunities for continued learning. Côté Gold’s commitments to Indigenous training and hiring through the Impact Benefit Agreements with Mattagami First Nation and Flying Post First Nation, includes partnering with First Nations representatives to ensure any barriers identified to employment are reviewed and where possible, resolved.

To further drive EDI across its operations, IAMGOLD has invested in key community partnerships, including the Canadian Board Diversity Council, which advances diversity on Canada’s boards through research, network building, board training and best practice education.

The Corporation has developed additional strategic partnerships to support and promote a workforce and work practices that are diverse and inclusive. Some of these partners include:

• Mining Association of Canada

• Mining Industry Human Resources Council

• Artemis Project

• International Women in Mining

• Canadian Centre for Diversity and Inclusion

• Women Who Rock

IAMGOLD’s work with these partners helps to establish and build appropriate frameworks for our EDI programming, and provides access to talent development and learning resources to embed inclusive behaviours and develop a culture of increased openness, respect and understanding of differences to fuel better collaboration and inclusion.

IAMGOLD has been selected for inclusion in the 2023 Bloomberg Gender Equality Index. The organization has been selected for inclusion in the Index in the last 4 out of 5 years. The GEI framework defines a set of metrics used to determine a company’s progress towards equal representation of gender throughout the levels of the organization, commitment to gender equality goals, policies in place to reduce the impact of familial stresses and responsibilities on the workplace, and progress towards positive impact on women outside of the employee base. The organization’s inclusion in the Gender Equality Index highlights its commitment to supporting gender equality through policy development, representation and data transparency.

2023 Management Proxy Circular IAMGOLD  |  80

BOARD PERFORMANCE ASSESSMENT

On an annual basis, the Board, through the NCGC, conducts a formal assessment of its effectiveness as a whole and of its committees, as well as the contribution of individual directors. Such assessments are carried out through written questionnaires and interviews which address, among other things, director engagement, Board composition and structure, Board and committee leadership, culture, and relationships. The NCGC discusses the results of the questionnaires and interviews and recommends to the Board any actions considered necessary or advisable to assist the Board in continuing to function effectively or to otherwise enhance its processes and performance. In addition to its internal assessment, the NCGC has the authority to engage external, independent advisors to assist with director performance assessments, as part of its overall Board evaluation process. Director performance, assessed against the competencies, skills and actual contributions the director brought to the Board during the year, factors significantly in the nomination of incumbent directors.

TERM LIMITS

In order to ensure that the Board benefits from a balance of fresh perspectives and the experience of longer-serving directors, the Corporation has adopted the Board Renewal Policy which recommends that the average tenure of the Board not exceed ten (10) years, the length of time for any Board chair or any committee not exceed ten (10) consecutive years. The Board Renewal Policy does not include term or age limits for individual directors as such limits could cause the Board to lose an established and experienced director necessary to ensure continuity and stability in transitioning new directors to the Board. Term limits, however, were approved by the Board for the Board chair and the chair of a Board committee in order to ensure that fresh and diverse perspective and insights are maintained in those roles. The Board’s membership has been substantially refreshed in recent years, with all directors nominated for election at the Meeting having joined the Board in the time since September 2021.

INDEPENDENCE AND IN CAMERA SESSIONS

When used to describe a director in this Statement of Corporate Governance Practices, the term “independent” has the meaning given to it by Canadian and United States securities regulatory authorities, specifically, a director who has no direct or indirect material relationship with the Corporation and is not otherwise deemed, under applicable regulatory requirements, to be non-independent. A “material relationship” with the Corporation being a relationship which could, in the view of the Board, be reasonably expected to interfere with the exercise of a director’s independent judgment. Neither compensation received solely in connection with directorship nor the holding of Common Shares of the Corporation (which is encouraged) constitutes such a material relationship.

The Board, through the NCGC, at least annually, reviews each director’s direct and indirect relationships with the Corporation, if any, to confirm their independence. The NCGC obtains information relating to these relationships from a variety of sources, including directors’ responses to an annual, detailed independence questionnaire that seeks to identify any connections between the Corporation and any director, or any family member or controlled entity of the director.

The Board has determined that all directors and director nominees for this year’s election of directors are independent, other than Mr. Adams, who was appointed as President and CEO of the Corporation effective April 1, 2023. Ms. Bélanger previously served as Interim President and CEO from May 3, 2022 to March 31, 2023. The Board has evaluated Ms. Bélanger’s independence following Mr. Adams’ appointment and has determined that she is independent for the purposes of applicable securities laws, as was the case when she was appointed to the Board in February 2022.

During Ms. Bélanger’s tenure as Interim President and CEO, the Board appointed Mr. Smith as Lead Independent Director in order to provide leadership to the independent directors. As Lead Independent Director, Mr. Smith

2023 Management Proxy Circular IAMGOLD  |  81

chaired all meetings of independent directors and works closely with the Board Chair with respect to meeting schedules and agendas for Board meetings.

The Board and its committees act independently, including, generally, conducting part of each of their meetings in camera (without management, affiliated, non-independent directors present) and deliberating and resolving on proposed actions from management and other material matters in such in camera sessions. In camera sessions facilitate open and candid discussion among independent directors. Approximately 83 such in camera sessions during Board and committee meetings were held in 2022, which represented a significant increase from previous years. In addition to regularly scheduled in camera sessions at meetings, generally held at the beginning and/or end of a meeting, any independent director, at any time, may request that management or any non-independent director not be present for all or any part of a meeting.

In camera sessions in 2022 have pertained to consideration of the CEO’s performance, shareholder engagement, director and management compensation and succession, material transactions, financing alternatives, project management, and the Board’s search for a permanent CEO, among other matters. In addition to in camera sessions held at Board and Board committee meetings, with a view to the integrity and reliability of the financial statements, the AFC regularly holds sessions that are attended only by the Corporation’s internal and external auditors to allow open discussions about their audits, including the assessment of internal controls over financial reporting, disclosure controls and procedures, and cooperation from management.

MEETING FREQUENCY, TIME COMMITMENT, ATTENDANCE AND INTERLOCKS

The Board met 28 times in 2022. This number of meetings represented a significant increase in the frequency of Board and committee meetings from previous years, reflecting the significant challenges faced by the Corporation in 2022 and the resulting time and attention required of directors. Absent compelling reasons, it is critical for directors to adequately perform their duties and responsibilities to the Corporation that they attend all Board and committee meetings they are required to attend. Each director’s attendance record for Board and committee meetings is considered by the NCGC when recommending director nominees for re-election to the Board. Even if not formal members, directors are encouraged to attend all committee meetings. In accordance with applicable regulatory requirements, the AFC meets at least every quarter to review financial reporting. Other standing committees of the Board meet at least twice each year and typically more frequently to ensure their mandates are adequately performed. The following table sets out the attendance record for all directors who served on the Board in 2022.

The Board values the knowledge, experience and additional perspective of members that sit on the boards of directors of a variety of other publicly traded companies. Provided they do not interfere with the expected commitment to the oversight of the Corporation’s business and affairs, the Board encourages directorships of companies that are likely to face business, regulatory and social issues similar to those faced by the Corporation from time to time.

When considering whether director nominees have sufficient time and attention to dedicate to IAMGOLD’s business and affairs, the NCGC will consider the number of outside boards of directors on which a director nominee sit, nature of the company or entity on whose board the director nominee sits, the complexity of the business, its legal obligations and the likely demand on a director’s time and attention (such as whether the company or entity is privately held or publicly held and therefore subject to continuous disclosure obligations). The NCGC also considers whether the company or entity is listed on a stock exchange and the requirements of that stock exchange (such as whether it is listed on the TSX or the TSX Venture Exchange), all with a view to determining whether a director nominee can devote the required time and resources to the Corporation.

The NCGC has determined that no director nominee sits on such number of other boards of directors that could compromise the expected commitment of time and attention to IAMGOLD’s business and affairs, as is reflected in their ~99% attendance at the previous years’ Board and committee meetings.

2023 Management Proxy Circular IAMGOLD  |  83

Interlocking relationships between directors are also monitored. No director serves on the board of directors of any other public company or other entity with any other director and thus there are no interlocking relationships. In addition, there are no interlocking relationships between directors and executive officers of the Corporation at other public companies or other entities.

BOARD ROLES AND RESPONSIBILITIES

The roles and responsibilities of the Board are prescribed by applicable law, its adopted mandate and the governance policies of the Corporation. The primary duty and responsibility of the Board is the stewardship of the Corporation, through the oversight of the management of the business, affairs and risks of the Corporation, with a view to the long-term creation and protection of stakeholder value. The Board oversees the following matters, among others:

• the adoption of strategic, capital and operating plans and budgets, at least annually;

• the performance of the CEO and other executive officers with a view to the successful execution and implementation of the strategic plan adopted by the Board;

• the maintenance of a culture of integrity throughout the organization through oversight of compliance with the Corporation’s Code of Business Conduct and Ethics;

• effective governance through the adoption of sound corporate governance structures and practices designed to ensure the Corporation’s assets are protected, its reputation is preserved and it continues to comply with all laws applicable to its business, wherever conducted;

• the identification of risks to the Corporation’s business and the implementation of appropriate detection, prevention and mitigation initiatives to manage such risks;

• oversight and monitoring of the Corporation’s approach, policies and practices related to ESG matters, including environmental-related risks and opportunities;

• oversight of fair and accurate financial reporting, including internal controls over financial reporting to ensure reliability and disclosure controls and procedures to ensure timely, accurate and complete reporting;

• the establishment of a communications policy to facilitate communications with investors and other stakeholders and avoid selective disclosure of material undisclosed information;

• executive management succession planning, including appointing and monitoring the performance of members of senior management, and oversight and approval of appropriate compensation programs; and

• director succession planning, such that the Board remains appropriately balanced in terms of the strategic skills, competencies and experience and diversity required amongst its members, including in the case of an unexpected departure of a director.

The Board discharges its oversight of the management of the Corporation directly and through its committees. The Board is regularly informed by management in connection with the day-to-day management of the business and affairs of the Corporation and, where issues arise in the execution or implementation of the approved strategic plan, expects management to recommend alternate strategies and actions that will maintain the long-term creation and protection of stakeholder value. The full responsibilities of the Board are set out in its mandate, a copy of which is set out in Appendix “A” to this Circular.

Directors are expected to be familiar and annually affirm their compliance with the Code of Business Conduct and Ethics and, in particular, rules concerning conflicts of interest and the expectation of withdrawal from any discussion, assessment or decision of the Board relating to any matter in which a director is conflicted. In addition to the Code of Business Conduct and Ethics, each of the Corporation’s directors are subject to the requirements

2023 Management Proxy Circular IAMGOLD  |  84

of the Canada Business Corporations Act, the Corporation’s governing legislation, and where a director declares an interest in any material contract or transaction being considered at a meeting of directors, the director, where appropriate, shall not attend any discussion, or vote, on the matter.

Board Leadership

Chair

The role and responsibilities of the Board Chair include the following:

Ensuring that the Board and its committees function independently of management.

Chairing Board meetings.

Developing the agenda for the Board meetings and schedules for Board and committee meetings.

Providing advice and counsel on Board meeting schedules to ensure there is sufficient time for all agenda items.

Evaluating and overseeing the quality, quantity and timeliness of the information submitted by management to the independent directors.

Acting as a liaison between the independent directors and senior management.

Being available for consultation and direct communication, under appropriate circumstances, if requested by investors and other stakeholders.

Performing such other duties and responsibilities as may be delegated to the Chair by the Board from time to time.

The Board Chair does not have an additional, tie-breaking vote in the event that directors are evenly split on a particular matter.

Committees of the Board

In order to assist in the performance of its mandate and oversight of the management of the Corporation, the Board has formed five standing committees: the Audit and Finance Committee, the Human Resources and Compensation Committee, the Nominating and Corporate Governance Committee, the Sustainability Committee and the Technical Committee. The Board may form other committees from time to time, as necessary or appropriate, to adequately address specific matters, such as the ad hoc Côté Project Review Committee, which was formed specifically to oversee management’s development and construction of the Côté Gold project. The membership of each standing committee and the Côté Project Review Committee is composed exclusively of independent directors who have the expertise necessary to successfully fulfill the mandate of the committee. As President and CEO of the Corporation, Mr. Adams does not serve on any standing committee of the Board, nor did Ms. Bélanger during her tenure as Interim President and CEO. As Board Chair, Ms. Bélanger does not serve as a member of any committee, but regularly attends committee meetings.

The chair of a committee is appointed by the Board on the recommendation of the NCGC. The committees are tasked with the performance of their mandates, which are reviewed by the NCGC and the committees on an annual basis, with any amendments being brought to the Board for approval, as applicable. Copies of the mandates of the various standing committees of the Board may be accessed on the Corporation’s website (at www.iamgold.com, under “Corporate Governance”). Each mandate empowers each committee to retain, at the cost of the Corporation, the services of such external advisors it deems necessary or advisable from time to time to assist it in the proper performance of its mandate. The Board and committee mandates, collectively, are designed to provide the governance framework necessary or advisable to fulfill the Board’s duties and responsibilities, particularly, in the effective oversight of management in the conduct of the Corporation’s business and affairs and the execution of the strategy adopted by the Board.

Audit and Finance Committee (AFC)

  MEMBERS:   Christiane Bergevin   Peter O’Hagan   David Smith (Chair)   Meetings Held in 2022: 9   The AFC consists of three (3) independent directors. The AFC’s responsibilities include the identification, prevention, detection and mitigation of financial control risks, and reviewing and recommending for Board approval the Corporation’s annual and quarterly financial statements and related regulatory disclosures, as prepared by management.
The AFC also reviews the process of preparing such disclosures through the oversight of internal and external auditors that review the Corporation’s internal controls over financial reporting and disclosure controls and procedures, the performance of such controls during the period to which the disclosures relate, the accounting principles used by management to compile the financial statements and the assumptions, judgments and estimates of management reflected in the financial statements. The AFC also recommends the nomination of the external auditor and pre-approves all non-audit services and fees thereof in an effort to monitor the external auditor's independence from management.

Mr. Smith joined the AFC on February 13, 2022 and has served as chair since February 24, 2022. Mr. O’Hagan joined the AFC on March 11, 2022. Ms. Bergevin joined the AFC on February 22, 2023. Mr. O’Kane served on the AFC from October 6, 2022 to February 22, 2023.

Further to a recommendation from the NCGC, the Board has determined that all members of the AFC are “financially literate”, at least one member is considered an “audit committee financial expert” and all members have the necessary time to commit to the AFC’s affairs. In the Board’s determination of the financial literacy of members of the AFC, which must be financially literate before the appointment to the AFC, the Board confirms that members possess the ability to read and understand a set of financial statements that present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of issues that can be reasonably expected to be raised by the Corporation’s financial statements. The Board also confirms that the members of the AFC have familiarity with the application of accounting principles, including in respect of judgment and estimates, accruals and reserves, an understanding of internal controls and procedures for financial reporting, familiarity with emerging accounting issues, past employment experience in finance or accounting, professional certification in accounting, and any other comparable experience or background which results in the member’s financial sophistication, including having been a CEO, CFO or other senior officer with financial oversight responsibilities.

The HRCC administers the Corporation’s shareholder-approved Share Incentive Plan, provides the Board with recommendations to match rewards with performance, and to align the interests of management and the Board with shareholders so that each share a similar corporate experience. Each member is experienced in matters pertaining to human resources and executive compensation by virtue of having been senior executives of publicly traded companies as well as members of boards and human resources/ compensation committees of other public companies.   Ms. Toutant has served as chair of the HRCC since February 23, 2022. Mr. Smith joined the HRCC on February 23, 2022.

Information related to the retention by the HRCC of any compensation consultant and the services performed by such consultant is also available in the Statement of Executive Compensation. Similar to the AFC maintaining the independence of the external auditor of the Corporation, in order that any compensation consultant retained by the HRCC from time to time be and remain independent from management, any services performed by such consultant for management must be pre-approved by the HRCC.

effective as of the date of the Meeting. A new member of the CPRC is expected to be selected following the Meeting.

POSITION DESCRIPTIONS

The Board has developed a written position description for the Board Chair and the chairs of committees. The primary responsibilities of the Board Chair (in addition to those dictated by the mandate of the Board, set out Appendix “A” to this Circular) are to, in conjunction with management or otherwise, plan, organize and chair all meetings of the Board and Shareholders, oversee the content of all information that directors and Shareholders are provided, ensure that the same is provided reasonably in advance of their meetings, and to provide leadership in the functioning and performance of the Board in accordance with its mandate. The Chair acts as the primary liaison between the Board and executive management.

During the time that the Board Chair was not an independent director, a Lead Independent Director was appointed in order to facilitate communication among the Corporation’s independent directors and between the independent directors and executive management. The role of the Lead Independent Director was to chair meetings of independent directors, serve as a liaison between the Board Chair and independent directors, and consults with the Board Chair regarding meeting schedules and agendas.

The mandates of the committees of the Board are reviewed and proposed to the committees by the NCGC, who review such proposals and recommend them to the Board for approval. Such committee mandates are designed to assist the Board in fulfilling its mandate by defining the authority, roles and responsibilities of each of the

2023 Management Proxy Circular IAMGOLD  |  88

committees and the committee chairs, who seek to ensure their respective mandates are effectively discharged. In addition, the Board has approved specific position descriptions for the chair of each committee. These mandates may be accessed on the Corporation’s website (at www.iamgold.com, under “Corporate Governance”).

The Board has developed a written position description for the CEO, whose primary responsibility is to provide leadership of the management of the Corporation and who is directly accountable to the Board. The CEO is responsible for the development and implementation of strategic and tactical plans for the Corporation, as adopted by the Board, the recruitment, development, and monitoring of performance of executive management, managing and monitoring the various exploration, development and producing assets of the Corporation, identifying and pursuing new opportunities for the Corporation, developing and maintaining a culture of integrity throughout the Corporation and protecting and enhancing the Corporation’s reputation. The CEO acts as the primary spokesperson for the Corporation.

DIRECTOR ORIENTATION AND CONTINUING EDUCATION

The Corporation typically provides newly-appointed directors with a series of informational sessions led by members of management which include in-depth reviews of directors’ duties and responsibilities; the roles and responsibilities of each of the Board’s committees; the Corporation’s various exploration, development and producing operations; and the actions management is taking in carrying out the Corporation’s strategic objectives, as determined by the Board. New directors are also provided with opportunities to meet with the Board Chair, the CEO, other independent directors or executive management, in order to familiarize themselves with the business and operations of the Corporation. Tours of IAMGOLD’s operations are also made available to new directors. Information and advice is also provided to directors by the Corporation’s general counsel regarding the duties and obligations of directors under applicable law. The mandates of the Board and its committees, the Code, minutes of the meetings of the Board and its committees and the most recent annual report, AIF and Circular are also provided.

In addition to regular updates on the Corporation’s operations, finances and risks, the Board received the following presentations and informational sessions in 2022:

Date	Topic	Attendees
March 4, 2022	Management Deep Dive – Operations and Projects – Management prepared a series of presentations to familiarize directors with each of the Corporation’s operations and projects.	Board of Directors

2023 Management Proxy Circular IAMGOLD  |  89

To assist directors with remaining current with respect to their duties and responsibilities, the Board recognizes the importance of ongoing director education and the need for each director to take personal responsibility for this process. To facilitate ongoing director education:

• directors are encouraged to participate in seminars or conferences of interest and relevance to their duties and responsibilities to the Corporation;

• visits to the Corporation’s various exploration, development and producing operations are arranged;

• directors are regularly and timely provided with updates from members of the executive management team regarding strategic issues or events affecting the Corporation, including its competitive environment, the Corporation’s performance relative to its peers and any other developments that could materially impact the Corporation’s business; and

• directors have full access to senior management and employees with respect to any information they may need in order to properly perform their duties.

In addition to information at Board and committee meetings, directors regularly receive, in the context of Board dinners and other informal meetings, presentations from management or outside parties with respect to developments relevant to the Corporation.

STATUTORY MAJORITY VOTING

Recent amendments to the Canada Business Corporations Act (the “CBCA”), the Corporation’s governing statute, provide Shareholders who are asked to elect directors at an uncontested meeting of shareholders with a statutory right to vote for or against director nominees. In the event that any director nominee does not receive a majority of votes in favour of their election, such director nominee will not be elected to serve as a member of the Board. In the event that any director nominee who failed to receive a majority of votes in favour of their election was an incumbent director, such incumbent director may remain in office until the earlier of (i) the 90th day after the date of the election; or (ii) the day on which their successor is appointed.

As result of the implementation of the above-described amendments to the CBCA, the Corporation has repealed its Majority Voting Policy. Under the terms of the former Majority Voting Policy, any director nominee who received a majority of votes by Shareholders withheld from their election to the Board would, subject to the very limited discretion of the Board, not be accepted as a director and any incumbent director receiving a majority of withhold votes would be required to immediately tender their resignation to the Board, which resignation would be accepted and effective, absent exceptional circumstances, within 90 days of the Shareholders meeting.

ADVANCE NOTICE OF DIRECTOR NOMINATIONS

The Corporation’s by-laws require that any Shareholder seeking to nominate one or more individuals to serve as directors at a Shareholder meeting provide reasonable advance notice of the individuals the Shareholder intends to nominate and information important for other Shareholders to be able to make an informed decision on the nominees. The by-laws provide for a reasonable time frame in which to notify the Corporation of an intention to nominate directors and require a level of disclosure of information concerning proposed nominees that the Board would have to provide in the case of Board nominees – the requirements being no more onerous than the requirements the Board is to meet in its nominations. This affords the NCGC, and the Board, a reasonable opportunity to evaluate the qualifications and suitability of all director nominees and to respond, as appropriate, in the best interests of the Corporation. This allows all Shareholders a reasonable opportunity and sufficient information to evaluate all director nominees and the Board’s recommendations so that they can make an informed vote with respect to every director nominee.

2023 Management Proxy Circular IAMGOLD  |  90

CODE OF BUSINESS CONDUCT AND ETHICS

In order to protect and advance the integrity and reputation of the Corporation, the Board has adopted the Code, which applies to all directors, officers, employees, contractors and representatives of the Corporation in every business in which it operates globally. All new employees are required to acknowledge and certify their understanding of their obligations under the Code upon commencement of their employment. Service providers are similarly required to acknowledge and abide by the provisions of the Code at the time of being contracted by the Corporation. The Code sets out fundamental principles upon which the business and affairs of the Corporation, wherever conducted, are based and is designed to promote integrity and deter wrongdoing. The Code provides that any conflict of interest with that of the Corporation is to be avoided, the assets and opportunities of the Corporation are to be protected and used solely for its benefit, non-public information pertaining to the Corporation is to be kept confidential and all laws applicable to the Corporation are to be complied with, wherever its business is conducted. For example, should a director or executive officer have an interest in an agreement or transaction with the Corporation being considered by the Board, such director or executive officer shall disclose their interest in the counterparty and withdraw from any discussion, assessment or decision of the Board relating thereto, including any Board vote thereon. A copy of the complete Code may be accessed on the Corporation’s website (at www.iamgold.com, under “Corporate Governance”).

Any material departure from the Code by a director or executive officer must be approved by the Board and promptly disclosed. There were no such departures from the Code in 2022. The Board believes that providing a means through which concerns may be raised about ethical conduct or departures from the Code, on an anonymous and confidential basis, fosters a culture of integrity and ethical conduct within the Corporation. Similar to allegations concerning the violation of laws or the Corporation’s internal controls over financial reporting or disclosure controls and procedures, any alleged departure from the Code may be, anonymously and confidentially, orally or in writing, reported, for investigation, to the chair of either or both the AFC and the NCGC, through the internet, a toll-free number and/or by mail. The reporting system is run by an independent third party. Any allegation involving a director is reviewed by the full Board, absent the director which is the subject of such allegation. The Corporation routinely conducts internal audits to test compliance with the Code and confirm its directors, officers and employees continue to be aware of the Code’s requirements as well as the resources available to report alleged breaches. The Corporation requires that, upon election, appointment or employment, and each year thereafter, each director, officer or employee acknowledge an understanding of the Code’s requirements. Given the fundamental nature of the Code, any transgression of its requirements by any officer or employee of the Corporation is grounds for disciplinary action up to and including termination of employment.

ENVIRONMENTAL, SOCIAL AND CORPORATE GOVERNANCE

The Corporation recognizes that community or social license in the places where it conducts operations is at least as important as strict compliance with legal and regulatory obligations to the successful operation of the Corporation’s business. To help meet its commitments, the Corporation works to develop and maintain meaningful partnerships with its host countries, communities, civil society and employees. IAMGOLD works to conduct its business in ways that are principled, transparent and accountable to all stakeholders, including Shareholders, employees, local communities, governments and the environment, all with a view to the creation and preservation of long-term Shareholder value. The Corporation focuses its efforts where it can have the most positive impact on its business and society, including issues related to environmental sustainability, trust, culture and human capital. As a reflection of the importance of these matters, the full Board oversees management’s execution of the Zero Harm^® strategic framework adopted. Management has formed a committee dedicated to the advancement of ESG in the Corporation’s activities.

Zero Harm^® reflects the Corporation’s commitment to continually strive to reach the highest standards in human health and safety, minimize the Corporation’s impact on the environment and work cooperatively with host communities. The full Board regularly receives presentations from management and has discussions concerning

2023 Management Proxy Circular IAMGOLD  |  91

the Corporation’s continued compliance with, and fostering of, Zero Harm^® in any of its activities and the processes used by management to monitor and manage environmental and social risk. The implementation of the Zero Harm^® framework is an ongoing journey which is continued in partnership with internal and external stakeholders.

Health and safety is core to the Corporation’s relentless pursuit of the Zero Harm vision. To maintain a healthy and safe workplace, the Corporation has been dedicated in building a culture of health and safety alongside its employees and promoting local community health and wellbeing.

In recognition of the strategic importance of environmental matters to the Corporation, the Board has taken a direct role in overseeing environmental matters with a view to being able to better predict and manage environmental issues that are anticipated to be most impactful to the Corporation’s business over the long term. The Board directly oversees and monitors the Corporation’s approach, policies and practices related to environmental matters and maintains general oversight of environmental-related risks and opportunities.

The Corporation also recognizes that mining activities are energy intensive and generate significant greenhouse gas emissions. The fight against climate change ultimately requires the mining industry to prioritize responsible energy use, improve efficiencies and explore new options for fuel switching and renewables. To that end, in September 2021 the Corporation announced its commitment to achieve net negative greenhouse gas (“GHG”) emissions by no later than 2050. This commitment comprises two separate global targets. The first global target relates to reductions in Scope 1 (direct) and Scope 2 (indirect – energy) GHG emissions. IAMGOLD is committing to reduce its emissions profile to as close to zero as possible by no later than 2050. Initial work will focus on defining specific options to address the Corporation’s largest sources of emissions: heavy and light vehicle fleets and power generation and supply. IAMGOLD’s commitments will be updated in 2025 to incorporate targets for its Scope 3 (indirect—value chain) emissions.

The second global target relates to GHG removals. Reversing the effects of climate change requires not only that emissions be reduced, but that substantial amounts of existing GHG also be removed from the atmosphere. As part of this target, IAMGOLD is committing to achieve net positive biodiversity, wherein the Corporation will commit to creating more habitat than it disturbs. The Corporation plans to achieve this global target through investments in nature-based solutions that further biodiversity objectives and act as carbon sinks. Investment opportunities will be pursued at the Corporation’s operating sites, as well as regionally and globally, to ensure the maximum possible benefit for every dollar invested. The Corporation is working at both the global and local level to advance these priorities and to reduce the Corporation’s carbon footprint. An external review of the Corporation’s greenhouse gas emissions profile across all sites is in progress.

Strong, environmental, social and governance practices have always been part of the way the Corporation does business. As the world moves toward a low carbon economy, the Corporation is proud of its commitment to sustainable development. The fight against climate change requires the mining industry to prioritize responsible energy use, improve efficiencies and explore new options.
