You are receiving this notification as Coveo Solutions Inc. (the "Corporation") has decided to use the notice and access procedures for delivery of the 2025 management proxy circular, the management's discussion and analysis for the year ended March 31, 2025, the consolidated financial statements of the Corporation and the auditor's report for the years ended March 31, 2025 and other related materials of the Meeting (collectively, the "Proxy Materials") to its shareholders and to advise that the Proxy Materials for the above noted shareholders' meeting are available on the Internet. Under the notice and access procedures, instead of receiving paper copies of the Proxy Materials, shareholders receive a copy of this notice and a form of proxy or voting instruction form, as applicable. Using the notice and access model for delivery reduces the Corporation's environmental footprint and substantially reduces its printing and mailing costs. This communication presents only an overview of the more complete Proxy Materials that are available to you on the Internet. We remind you to access and review all of the information contained in the Proxy Materials, before voting.

The Proxy Materials are available at:

ir.coveo.com

OR

www.sedarplus.ca

How to obtain paper copies of the Proxy Materials

The Corporation will provide a paper copy of the Proxy Materials to any shareholder upon request, free of charge, for a period of 1 year from the date the 2025 management proxy circular is filed on SEDAR+.

You may request a paper copy at any time before the meeting on the web at investors@coveo.com or by contacting TSX Trust Company at 1-888-433-6443 (toll free in Canada and the United States) or 416-682-3801 (other countries). Please be sure to keep your form of proxy (for registered shareholders) or voting instruction form (for non-registered shareholders), because you will not receive another copy if you request a paper copy of the Proxy Materials. To ensure shareholders receive paper copies of the Proxy Materials in advance of the voting deadline for the 2025 annual general meeting of shareholders, shareholders should send their request before August 27, 2025.

After the meeting, such requests may be made by calling the same numbers or by e-mailing your request at tsxt-fulfilment@tmx.com. Please allow a period of 3 business days for processing your request as well as usual mailing times.
