Form of Proxy

I/We, being holder(s) of Class A subordinate voting shares of Alithya Group inc. (the "Company"), hereby appoint: Pierre Turcotte, Chair of the Board, or failing him, Paul Raymond, director and President and Chief Executive Officer, or:

Print the name of the person you wish to appoint if this person is someone else than the persons listed above

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 APPOINT SOMEONE ELSE THAN THE PERSONS NAMED BY MANAGEMENT AS THEIR PROXYHOLDER:

If you wish to appoint someone else than the directors named by management on this form of proxy as your proxyholder to attend and vote on your behalf at the Meeting, (i) YOU MUST return your form of proxy by mail, fax or email or submit your appointment to TSX Trust Company ("TSX Trust") 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 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 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. Such 13-digit proxyholder control number will differ from the control number set forth on this form of proxy. As it is not possible to appoint someone else than the two directors named by management on this form of proxy by telephone, voting by telephone is not recommended.

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

The control number appearing on this form of proxy is NOT a proxyholder control number and may therefore not be used by your proxyholder to attend and vote at the Meeting on your behalf under your proxyholder's name.

VOTING RECOMMENDATIONS ARE INDICATED BY HIGHLIGHTED TEXT OVER THE BOXES.

Please use a dark black pencil or pen.

This form of proxy is solicited by and on behalf of management.

Notes

1. As a registered shareholder, for your shares' voting rights to be exercised at the Meeting, it is necessary that you either attend the Meeting yourself or appoint a proxyholder to represent you. If you decide to appoint a proxyholder to represent you at the Meeting and vote on your behalf, you may either (i) appoint the persons named by management and whose names appear on this form of proxy (by leaving the appointment space at the top of the reverse blank) or (ii) appoint someone else (by writing such 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 or any adjournment or postponement thereof. If you appoint someone else than the persons named by management, you should, however, 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. Please refer to the reverse side for more information on the procedure to obtain a proxyholder control number. It is recommended to vote by proxy prior to the Meeting even if you intend to attend the Meeting, to make sure your shares' voting rights are exercised, should you be unable to attend the Meeting for any reason.

2. The shares' voting rights represented by this proxy will be voted as instructed by you. If, however, instructions are not made in respect of any matter, the shares' voting rights will be voted as recommended by management, if the persons named by management are appointed as proxyholder, or, if they are not, as your proxyholder sees fit. This form of proxy also confers discretionary authority to the proxyholder to vote as such person sees fit in respect of any amendments to matters identified in the notice of meeting or other matters that may properly be brought at the Meeting or any adjournment or postponement 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 VIP or in the management information circular. Please consult a legal advisor if you wish to modify the authority of your proxyholder in any way.

3. If the shares are registered in the name of more than one shareholder, at least one of the shareholders must sign. If the shares are registered in the name of a corporation or other legal entity, an authorized officer or representative must sign and indicate their signing capacity. The signatory may be requested to provide proof of signing authority.

4. This form of proxy should be read in conjunction with the management information circular and other Meeting materials.

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