Notice-and-Access The Canadian securities regulators have adopted rules which permit the use of notice-and-access for proxy solicitation instead of the traditional physical delivery of material. This new process provides the option to post meeting related materials including management information circulars, as well as annual financial statements and management’s discussion and analysis on a website in addition to SEDAR. Under notice-and-access, meeting related materials will be available for viewing for up to 1 year from the date of posting and a paper copy of the material can be requested at any time during this period. Docebo Inc. has elected to utilize notice-and-access and provide you with the following information: Meeting Date and Time: June 13, 2023 at 9:00 a.m. (eastern time) Meeting Location: Virtual meeting link: https://virtual-meetings.tsxtrust.com/1425 Meeting materials are available electronically at www.sedar.com and also on https://docs.tsxtrust.com/2177.
