as my/our proxyholder to attend, act and vote on my/our behalf in accordance with the below instructions (or if no instructions are given, as my/our proxyholder sees fit) on all the matters outlined below and any other matter that may properly come before the annual general meeting of shareholders of the Company to be held at 10:00 a.m. (Eastern Daylight Time) on Wednesday, September 10, 2025, in a virtual format via a live audio webcast online at meetings.lumiconnect.com/400-353-766-264 (the "Meeting"), and at any and all adjournments or postponements thereof in the same manner, to the same extent and with the same powers as if I/we attended it, with full power of substitution.

IMPORTANT NOTES FOR SHAREHOLDERS WHO WISH TO ATTEND THE MEETING OR APPOINT SOMEONE ELSE THAN THE PERSONS NAMED BY MANAGEMENT AS THEIR PROXYHOLDER:

If you wish to attend the Meeting, you MUST appoint yourself as your proxyholder. If you decide to appoint yourself or someone else than the two directors named by management on this voting instruction form (“VIF”) as your proxyholder to attend and vote at the Meeting, (i) YOU MUST return your VIF by mail, fax or email or submit your appointment and voting instructions using the internet AND (ii) YOU OR YOUR PROXYHOLDER MUST ALSO either complete the online form available at www.tsxtrust.com/control-number-request or call TSX Trust Company (“TSX Trust at 1-866-751-6315 (toll free in Canada and the United States) or 1-416-682-3860 (other countries) by no later than 10:00 a.m. (Eastern Daylight Time) on September 8, 2025 to register yourself or your proxyholder and provide an email address at which TSX Trust will send a 13-digit proxyholder control number 24 to 48 hours before the Meeting. As it is not possible to appoint a person other than the two directors named by management on this VIF by telephone, voting by telephone is not recommended.

The proxyholder control number you or your proxyholder will receive via email will allow you or your proxyholder to attend and vote at the Meeting. Without such proxyholder control number, you or your proxyholder will only be able to attend the Meeting as a guest and will not be able to vote or ask questions and your voting rights will not be exercised as a proxyholder must attend the Meeting for them to be exercised.

The control number appearing on this VIF is NOT a proxyholder control number and may therefore not be used by you or your proxyholder to attend and vote at the Meeting.

VOTING RECOMMENDATIONS ARE INDICATED BY HIGH JOINTED TEXT OVER THE BOXES.

Please use a dark black pencil or pen.

Voting Instruction Form (“VIF”) – Annual General Meeting of Shareholders of Alithya Group inc. (the “Company”) to be held at 10:00 a.m. (Eastern Daylight Time) on September 10, 2025 (the “Meeting”)

This VIF is solicited by and on behalf of management.

Notes

1. The enclosed proxy-related materials are being sent to you in connection with the Meeting of the Company, of which you hold shares through an intermediary.
2. As you hold shares through an intermediary and not directly in your name, you are a non-registered shareholder. As such, for your shares to be voted at the Meeting, it is necessary that you appoint a proxyholder – even if you wish to attend the Meeting yourself. To appoint a proxyholder, you can either (i) appoint the persons named by management on this VIF for them to represent you at the Meeting and vote on your behalf (by leaving the appointment space at the top of the reverse blank) or (ii) appoint yourself or someone else to attend and vote at the Meeting (by writing your name or such other person's name in the appointment space at the top of the reverse). Shareholders have the right to appoint the person of their choice, who need not be a shareholder, to attend and act on their behalf at the Meeting and any adjournment or postponement thereof. If you wish to attend the Meeting and vote yourself, please write your name. Your intermediary is prohibited from voting your shares on any of the matters to be acted upon at the Meeting. If you appoint someone else than the persons named by management, you should ensure that such person attends the Meeting using a proxyholder control number at the time of the Meeting, otherwise, your voting rights will not be exercised.
3. The shares' voting rights represented by this VIF will be voted as instructed by you. If, however, instructions are not given in respect of any matter, the shares' voting rights represented by this VIF will be voted as recommended by management, if the persons named by management are appointed as your proxyholder, or, if they are not, as such other proxyholder sees fit. This VIF also confers discretionary authority to the proxyholder to vote as such person sees fit in respect of amendments or variations to matters identified in the notice of meeting or other matters as may properly come before the Meeting or any adjournment thereof. Unless prohibited by law, your proxyholder will have full authority to vote on all matters that are presented at the Meeting and which are not set out in this VIF or in the management information circular. Please consult a legal advisor if you wish to modify the authority of your proxyholder in any way.
4. By providing voting instructions, you are acknowledging that you are the beneficial owner of, and are entitled to direct the voting of, the shares represented by this VIF.
5. If the shares are registered in the name of more than one shareholder, at least one of the shareholders must sign this VIF. If the shares are registered in the name of a corporation or other legal entity, an authorized officer or representative must sign this VIF and indicate their signing capacity. The signatory may be requested to provide proof of signing authority.
6. If you have any questions regarding the enclosed documents or require assistance, please contact a registered representative at the intermediary who services your account or TSX Trust at 1-800-387-0825 or by email at shareholdering.iries@tmx.com.
7. This VIF should be read in conjunction with the management information circular and other Meeting materials.

All voting instructions must be received by 10:00 a.m. (Eastern Daylight Time) on September 8, 2025.
