Notice to shareholders of Algonquin Power & Utilities Corp. regarding notice-and-access April 14, 2022 Dear shareholder, In connection with the annual meeting (the “Meeting”) of the shareholders (the “Shareholders”) of Algonquin Power & Utilities Corp. (the “Corporation”), notice is hereby given that the Corporation will use the Canadian Securities Administrators’ “notice-and-access” delivery model to deliver proxy-related materials, including the Corporation’s management information circular (the “Circular”) and the Corporation’s 2021 annual report containing the Corporation’s audited consolidated financial statements and the auditor’s report thereon and management’s discussion and analysis for the year ended December 31, 2021 (the “Annual Report” and, together with the Circular, the “Meeting Materials”) to Shareholders. Under notice-and-access, the Corporation is permitted, as an alternative to sending paper copies of the Meeting Materials to Shareholders, to provide to Shareholders of record as of April 11, 2022, the record date for the Meeting, this notice containing, among other things, information regarding how to access the Meeting Materials online as well as how to obtain paper copies of the Meeting Materials free of charge. The Corporation anticipates that notice-and-access will directly benefit the Corporation through a substantial reduction in both postage and printing costs and will also promote environmental responsibility by decreasing the large volume of paper documents generated by printing proxy-related materials.
