TO VOTE AHEAD OF THE VIRTUAL AGM
As in prior years, shareholders have multiple options to cast their vote ahead of the AGM, which include on-line, via telephone or via mail.

Shareholders who are planning to vote ahead of the AGM must submit their proxy voting instructions to Computershare no later than 9:30 a.m. (Eastern Daylight Time) on Tuesday, April 19, 2022.

A notice package containing a description of the matters to be addressed at the AGM and of the notice-and-access procedures to access the meeting materials, as well as a form of proxy (for registered shareholders) or a voting instruction form (for non-registered shareholders) (collectively, the "Notice Package") was mailed on or about March 17, 2022. If you have not yet received your copy of the Notice Package, please contact your broker if you are a non-registered shareholder or contact Computershare if you are a registered shareholder. These materials outline in detail how to participate at the AGM.

The Meeting Materials are available to view at Quarterhill's profile on SEDAR at www.sedar.com as well as in the Investor Section of Quarterhill's website at www.quarterhill.com.

All shareholders wishing to have a question addressed at the virtual AGM can avoid the registration requirements set out in the Circular by submitting them in advance to [email protected].

Quarterhill is committed to addressing all appropriate questions submitted by shareholders either live during the AGM or in advance, as timing and circumstances permit.

Shareholders who have questions on how to vote their proxy in advance of the AGM, or on how to register to vote at the AGM, can contact Quarterhill's strategic shareholder advisor and proxy solicitation agent, Kingsdale Advisors, at 1-855-476-7980 or, from outside North America, by collect call to 1-416-867-2272, or by Email at: [email protected].

About Notice and Access
As permitted by the Canadian Securities Administrators and pursuant to exemptions from the management proxy solicitation and financial statement and management's discussion and analysis delivery requirements received from the Director appointed under the Canada Business Corporations Act, Quarterhill is using "notice and access" to deliver proxy-related materials including Quarterhill's notice of meeting, management information circular and related materials (collectively the "Meeting Materials") to both registered and non-registered shareholders. "Notice and access" is a set of rules for reducing the volume of materials that must be physically mailed to shareholders by posting the Meeting Materials online and providing shareholders with a notice stating where they are available. Rather than receiving a paper copy of the Meeting Materials in the mail, shareholders will have access to them online and will receive a Notice Package as described earlier in this release. Where a shareholder has previously consented to electronic delivery, the Notice Package will be sent to the shareholder electronically, and otherwise will be mailed to the shareholder.
