At the time the Meeting was adjourned, proxies had been submitted by shareholders representing 32.76% of the Company's common shares outstanding and entitled to vote, which did not constitute the requisite 331/3% quorum pursuant to the Company's by-laws.

The deadline for submission of proxies has been extended to September 4, 2024 at 1 p.m. (ET). Proxies previously submitted with respect to the Meeting will be voted on all proposals at the adjourned Meeting unless properly revoked and shareholders who have previously submitted a proxy or otherwise voted need not take any action.

The details of the Meeting, including how to attend the Meeting, are set out in the Proxy Statement. The record date for the determination of shareholders entitled to vote at the Meeting remains July 15, 2024.
