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.

Disclosure regarding each matter or group of matters to be voted on is in the Information Circular in the Section with the same title as each Resolution on the reverse. You should review the Information Circular before voting.

KWESST Micro Systems Inc. has elected to utilize notice-and-access and provide you with the following information:

Meeting materials are available electronically at www.sedar.com and also at https://docs.tsxtrust.com/2214

If you wish to receive a paper copy of the Meeting materials or have questions about notice-and-access, please call 1-866-600-5869 or email TMXEInvestorServices@tmx.com. In order to receive a paper copy in time to vote before the meeting, your request should be received by March 19, 2021.

Request for Financial Statements

In accordance with securities regulations, security holders may elect to receive Annual Financial Statements and MD&A.

Instead of receiving the financial statements by mail, you may choose to view these documents on SEDAR at www.sedar.com.
