Details of the Tender Offer

The Company has been advised by Global Bondholder Services Corporation (GBSC), as information agent and tender agent, that as of 5:00 p.m., New York City time, on November 5, 2025 ("Early Tender Time"), U.S.$504,578,000 aggregate principal amount of Notes had been validly tendered and not validly withdrawn. The consideration for each U.S.$1,000 principal amount of Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Time and accepted for purchase pursuant to the Tender Offer (the "Total Consideration") will be U.S.$1,000. The Total Consideration includes an early tender payment (the "Early Tender Payment") equal to U.S.$50 per U.S.$1,000 principal amount of Notes, which is payable in respect of Notes validly tendered (and not validly withdrawn) and accepted for purchase pursuant to the Tender Offer. Holders of Notes ("Holders") whose Notes are accepted for purchase in the Tender Offer will also receive accrued and unpaid interest on such Notes from the last interest payment date to, but not including, the applicable settlement date.

Pursuant to the Offer to Purchase, and subject to the terms and conditions of the Tender Offer set forth therein, the Company intends to accept for purchase U.S.$300.0 million aggregate principal amount of the Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Time. The Company has not exercised its right to have an early settlement date at this time, but reserves the right to make such election prior to the Expiration Time (as defined below).

The following table sets forth the principal amount of the Notes tendered, the principal amount the Company intends to accept for purchase, the outstanding principal amount after the Tender Offer, and the proration factor.

The Tender Offer will expire at 5:00 p.m., New York City time, on November 21, 2025, unless extended or earlier terminated by the Company in its sole discretion (such time and date, as the same may be extended, the "Expiration Time"). In addition, the withdrawal deadline of 5:00 p.m., New York City time, on November 5, 2025, for the Tender Offer has now passed. Accordingly, Notes validly tendered in the Tender Offer may not be withdrawn. Holders who tender (and do not validly withdraw) their Notes after the Early Tender Time but at or prior to the Expiration Time will be eligible to receive U.S.$950 per U.S.$1,000 principal amount of Notes, which is (i) the Total Consideration minus (ii) the Early Tender Payment. The Company will only accept for purchase Notes up to the Maximum Amount. Since the Maximum Amount has been reached in respect of tenders of Notes made at or prior to the Early Tender Time, no further Notes will be accepted for purchase.

In addition, to the extent legally permitted to do so, the Company reserves the right, in its sole discretion, at any time to (i) waive any condition to the Tender Offer, (ii) amend any of the terms of the Tender Offer, (iii) terminate the Tender Offer, (iv) increase the Maximum Amount, (v) extend the Withdrawal Deadline, (vi) extend or amend the Expiration Time, or (vii) modify the Tender Offer Consideration, in each case (other than clause (v)) without extending the Withdrawal Deadline or otherwise reinstating withdrawal rights of Holders, subject to applicable law.
