The Arrangement Resolution was approved by 89.14% of the 121,792,144 votes cast by Company Voting Shareholders, and 65.91% of the 38,781,229 votes cast by disinterested Company Voting Shareholders, present in person or represented by proxy at the special meeting of shareholders held earlier today. The Company has therefore satisfied its shareholder approval requirements in respect of the Arrangement Resolution, being approval by not less than (i) 66 2/3% of the votes cast by Company Voting Shareholders voting as a single class, and (ii) a majority of the votes cast by disinterested Company Voting Shareholders.

“The strong voting support in favour of the transaction clearly demonstrates that our shareholders recognize that it is an opportunity for them to best maximize the value of their current investment, be it by taking advantage of the premium cash offer, remaining invested in the North American market opportunity, or a combination of both,” said Mark Redmond, President and CEO of SiriusXM Canada. With these shareholder approvals in place, we will continue to work to secure the necessary regulatory approvals to close the transaction in a timely manner.”

The Arrangement is subject to the approval and issuance of a final order by the Ontario Superior Court of Justice (Commercial List) (the “Court”), the receipt of regulatory approval from the Canadian Radio-television and Telecommunications Commission and the satisfaction or waiver of other customary closing conditions. The Company and the Court have been advised by the investor group, which had opposed the arrangement to date, that it will not be appearing to oppose approval of the Arrangement at the fairness hearing. The fairness hearing, at the request of the Court, has been adjourned from Friday, September 2, 2024 to Tuesday, September 6, 2024 at 9:30 am (EST). In addition, the Company has confirmed that no shareholders exercised dissent rights in connection with the Arrangement Resolution.
