Imperial Oil : Notice and Access Notification Letter

You are receiving this notification as Imperial Oil Limited ("Imperial") uses the notice and access model for delivery of meeting materials to its shareholders. In connection with the use of notice and access, on January 16, 2024, Corporations Canada exempted Imperial from sending the management proxy circular and annual financial statements to each shareholder whose proxy is solicited. The notice and access model adopted by the Canadian securities regulators, as supplemented by this exemption, allows for the posting of meeting related material online, including the management proxy circular, annual financial statements and related management discussion and analysis.

Shareholders will receive a proxy or voting instruction form enabling them to vote at Imperial's annual meeting, along with this notice containing information on how they may access the meeting related material electronically. Meeting related materials will not be mailed to shareholders unless a shareholder follows the instructions on the reverse under "How to Obtain Paper Copies of the Meeting Material". The use of this alternative means of delivery reduces the use of printed paper materials and has significantly reduced printing and mailing costs associated with the company's shareholder meeting.
