(the "Company" or "Alamos") for use at the annual general and special meeting of the shareholders of the Company (the "Meeting") (and at any adjournment thereof) to be held as a virtual meeting, which will be conducted via live webcast on Thursday, May 23, 2024, at 4:00 p.m., Toronto time. The information set out in this Circular is given as at April 1, 2024, unless otherwise indicated. All dollar amounts referenced in this Circular are in United States Dollars ("USD$"), unless otherwise specified. The exchange rate as at December 31, 2023, was Canadian Dollar ("CAD$") 1.00 = USD$0.7561, and the average exchange rate for 2023 was CAD$1.00 = USD$0.7409.

Record Date for Voting at the Meeting

The Board of Directors (the "Board") has set the close of business on April 10, 2024, as the record date (the "Record Date") for determining which shareholders shall be entitled to receive notice of and to vote at the Meeting. Only shareholders of record as of the Record Date shall be entitled to receive notice of and to vote at the Meeting, unless after the Record Date, a shareholder transfers his or her common shares of the Company (the "Common Shares") and the transferee (the "Transferee"), upon establishing that the Transferee owns such Common Shares, requests in writing, at least 10 days prior to the Meeting or any adjournments thereof, that the Transferee may have his or her name included on the list of shareholders entitled to vote at the Meeting, in which case the Transferee is entitled to vote such shares at the Meeting. Such written request by the Transferee shall be sent to the Company's Senior Vice President, General Counsel at the following email: notice@alamosgold.com.

Notice and Access

This year, the Company is using the "notice-and-access" system for the delivery of the Circular and 2023 annual report to both beneficial and registered shareholders, which includes the Company's management's discussion and analysis and annual audited consolidated financial statements for the fiscal year ended December 31, 2023 (collectively, the "Meeting Materials").

Under notice-and-access, you will still receive a proxy or voting instruction form enabling you to vote at the Meeting. However, instead of a paper copy of the Circular, you receive a notice document which contains information about how to access the Meeting Materials electronically. One benefit of the notice-and-access system is that it reduces the environmental impact of producing and distributing paper copies of documents in large quantities.

The Circular and form of proxy (or voting instruction form, as applicable) provide additional information concerning the matters to be dealt with at the Meeting. You should access and review all information contained in the Circular before voting.

Our Meeting Materials can be viewed online on our website at www.alamosgold.com, under our profile on SEDAR+

at www.sedarplus.ca, our profile on EDGAR at www.sec.gov/edgar, or at http://www.envisionreports.com/ALAMOSGOLD2024.

How We Will Solicit Proxies

The Company will bear the expense of this solicitation. It is expected the solicitation will be made primarily by mail, but regular employees or representatives of the Company (none of whom shall receive any extra compensation for

these activities) may also solicit by telephone, electronically and in person and arrange for intermediaries to send this Circular and the form of proxy to their principals at the expense of the Company.

The contents and the sending of this Circular have been approved by the Board.

Appointment and Revocation of Proxies

The persons named in the accompanying form of proxy are designated as proxyholders by management of the Company. A SHAREHOLDER WISHING TO APPOINT SOME OTHER PERSON (WHO NEED NOT BE A SHAREHOLDER) TO REPRESENT HIM OR HER AT THE MEETING MAY DO SO by submitting your proxy to Computershare by 4:00 p.m. (Toronto Time) on May 21, 2024. You MUST also go to http://www.computershare.com/alamosgold and provide Computershare with the name and email address of such appointed person, by 4:00 p.m. (Toronto time) on May 21, 2024, so that Computershare may provide the proxyholder with a Username via email.

Any registered shareholder who has returned a proxy may revoke it at any time before it has been exercised. In addition to revocation in any other manner permitted by law, a proxy may be revoked by instrument in writing, including a proxy bearing a later date, executed by the registered shareholder or by an attorney authorized in writing or, if the registered shareholder is a corporation, under its corporate seal or by an officer or attorney thereof duly authorized.

The instrument revoking the proxy must be emailed to the Company at notice@alamosgold.com at any time up to and including the last business day preceding the date of the Meeting or any adjournment thereof duly authorized. Only registered shareholders have the right to revoke a proxy. Beneficial shareholders who wish to change their vote must, at least seven (7) days before the Meeting, arrange for their respective intermediaries to revoke the proxy on their behalf.

Provisions Relating to Voting of Proxies

The Common Shares represented by proxy will be voted or withheld from voting by the designated proxyholder in accordance with the instructions of the shareholder appointing him or her on any ballot that may be called for and, if the shareholder specifies a choice with respect to any matter to be acted upon, the Common Shares will be voted accordingly. If there are no instructions provided by the shareholder, those Common Shares will be voted in favour of all proposals set out in this Circular. The proxy gives the person named in it the discretion to vote as they see fit on any amendments or variations to matters identified in the Notice of Meeting, or any other matters which may properly come before the Meeting. At the time of printing of this Circular, the management of the Company knows of no other matters which may come before the Meeting other than those referred to in the Notice of Meeting.

Advice to Beneficial Shareholders of Common Shares

The information set forth in this section is significant to many shareholders as a substantial number of shareholders do not hold Common Shares in their own names. Beneficial shareholders should note that only proxies deposited by shareholders whose names appear on the records of the Company as the registered holders of Common Shares can be recognized and acted upon at the Meeting. If Common Shares are listed in an account statement provided to a shareholder by a broker, then in almost all cases, those Common Shares will not be registered in the shareholder's name on the records of the Company. Such Common Shares will more likely be registered under the name of the shareholder's broker or an agent of that broker. In Canada, most of such Common Shares are registered under the name of CDS & Co. (the registration name for The Canadian Depository for Securities Limited, which acts as nominee for many Canadian brokerage firms). Common Shares held by brokers or their agents or nominees can only be voted (for, withhold or against resolutions) upon the instructions of the beneficial shareholders. Therefore, beneficial shareholders should ensure that instructions respecting the voting of their Common Shares are communicated to the appropriate person well in advance of the Meeting.
