Enerflex

ANNUAL AND SPECIAL MEETING OF SHAREHOLDERS

NOTICE AND ACCESS NOTIFICATION TO SHAREHOLDERS

As permitted by Canadian securities regulators, Enerflex Ltd. (Enerflex, the Company, or our) is using the notice and access model for the delivery of meeting materials to its shareholders (Shareholders) in connection with the annual and special meeting of the Shareholders of Enerflex (the Meeting). Under notice and access, Shareholders still receive a proxy or voting instruction form, as applicable, enabling them to vote in advance of the Meeting. However, instead of receiving a paper copy of our Management Information Circular dated March 20, 2026 (the Circular), Shareholders receive this notice explaining how to access the Circular and other meeting materials electronically. This reduces our printing and mailing costs and reduces the environmental impacts associated with producing and distributing printed meeting materials.
