Our obligation to accept Existing Notes tendered pursuant to the Exchange Offer and Consents delivered pursuant to the Solicitation is subject to the satisfaction of certain conditions described in the Exchange Offer Memorandum, which include, (i) the non-occurrence of an event or events or the likely non-occurrence of an event or events that would or might reasonably be expected to prohibit, restrict or delay the consummation of the Exchange Offer or materially impair the contemplated benefits to us of the Exchange Offer, (ii) the valid receipt (and not valid revocation) of the Consents of Eligible Holders of Existing Notes that, in the aggregate, represent not less than 66-2/3% in aggregate principal amount of the Existing Notes outstanding to effect the Proposed Amendments (the “Required Holders”) prior to the Early Participation Deadline, (iii) the valid tender (and not valid withdrawal) of Existing Notes by Eligible Holders in the Exchange Offer that, in the aggregate, represent not less than 80% in aggregate principal amount of the Existing Notes outstanding prior to the Early Participation Deadline (the “Minimum Exchange Condition”), and (iv) the consummation of an incurrence of new indebtedness, on terms and subject to conditions satisfactory to us, that results in the receipt of net proceeds that are sufficient to pay the Cash Consideration (as defined below) (such condition the “Financing Condition”), certain other customary conditions. The Company reserves the right to waive the conditions to the Exchange Offer at any time.

Existing Notes tendered for their exchange on or prior to the Early Participation Deadline may be validly withdrawn, and the related Consents may be validly revoked, at any time prior to 5:00 p.m., New York City time, on February 10, 2026, unless extended by the Company, in its sole discretion (the “Withdrawal Deadline”).

Eligible Holders who validly tender Existing Notes and deliver Consents, and do not validly revoke such tenders and Consents, on or prior to 5:00 p.m., New York City time, on February 11, 2026, unless extended or earlier terminated by the Company, in its sole discretion (the “Early Participation Deadline”) and whose Existing Notes are accepted for exchange by the Company will receive for each US$1,000 aggregate principal amount of Existing Notes validly tendered (and not validly withdrawn) on or prior to the Early Participation Deadline, US$1,000 a portion of which will be payable in cash and the remainder will be payable in principal amount of New Notes (the “Total Consideration”). The Total Consideration includes an early participation premium for each US$1,000 aggregate principal amount of Existing Notes validly tendered (and not validly withdrawn) on or prior to the Early Participation Deadline equal to US$50 (the “Early Participation Premium”), payable on the Early Settlement Date.

The aggregate cash consideration payable as part of the Total Consideration (which includes the Early Participation Premium) to all Eligible Holders whose Existing Notes are validly tendered (and not validly withdrawn) on or prior to the Early Participation Deadline and whose Existing Notes are accepted for exchange will be equal to an amount determined as follows: the aggregate cash consideration payable as part of the Total Consideration will be $110.0 million if 80% in aggregate principal amount of the outstanding Existing Notes are validly tendered (and not validly withdrawn) on or prior to the Early Participation Deadline, with such aggregate cash consideration amount to increase by US$750,000 for each incremental 1.0% of aggregate principal amount of outstanding Existing Notes validly tendered (and not validly withdrawn) on or prior to the Early Participation Deadline, up to maximum amount of cash consideration of US$125.0 million if 100% in aggregate principal amount of the outstanding Existing Notes are validly tendered (and not validly withdrawn) on or prior to the Early Participation Deadline (such amount, the “Cash Consideration”).   The pro rata portion of the Cash Consideration as part of the Total Consideration for each US$1,000 aggregate principal amount of Existing Notes validly tendered (and not validly withdrawn) on or prior to the Early Participation Deadline, and accepted for exchange, will be determined at the Early Participation Deadline, based on the aggregate amount of Existing Notes validly tendered (and not validly withdrawn) on or prior to the Early Participation Deadline.

The greater the amount of Existing Notes validly tendered (and not validly withdrawn), the lower the pro rata portion of the Cash Consideration per US$1,000 aggregate principal amount of Existing Notes tendered (and not validly withdrawn). For example: (i) if 100% of the Existing Notes outstanding is validly tendered (and not validly withdrawn) on or prior to the Early Participation Deadline, each Eligible Holder will receive, for each US$1,000 aggregate principal amount of Existing Notes validly tendered (and not validly withdrawn), approximately US$174.50 in cash and approximately US$825.50 in aggregate principal amount of New Notes, and (ii) if 80% of the Existing Notes outstanding is validly tendered (and not validly withdrawn) on or prior to the Early Participation Deadline, each Eligible Holder will receive, for each US$1,000 aggregate principal amount of Existing Notes validly tendered (and not validly withdrawn), approximately US$191.95 in cash and approximately US$808.05 in aggregate principal amount of New Notes.

Eligible Holders who validly tender Existing Notes and deliver Consents after the Early Participation Deadline and on or prior to 5:00 p.m., New York City time, on February 27, 2026, unless extended by the Company, in its sole discretion (the “Expiration Deadline”) and whose Existing Notes are accepted for exchange by us will receive for each US$1,000 aggregate principal amount of Existing Notes validly tendered (and not validly withdrawn), US$950 aggregate principal amount of New Notes (the “Exchange Consideration”).

Eligible Holders whose Existing Notes are accepted for exchange will be paid accrued and unpaid interest on such Existing Notes from, and including, the most recent date on which interest was paid on such Holder’s Existing Notes to, but not including, the Early Settlement Date or the Settlement Date, as applicable (the “Accrued Interest”), payable on the Early Settlement Date or the Settlement Date, as applicable. Accrued Interest will be paid in cash on the Early Settlement Date or the Settlement Date, as applicable. Interest will cease to accrue on the Early Settlement Date or the Settlement Date, as applicable, for all Existing Notes accepted for exchange in the Exchange Offer.

At any time after the Withdrawal Deadline and before the Expiration Deadline, if the Company has received the Consent of Required Holders of Existing Notes, the Company and the trustee under the Existing Indenture may execute and deliver a Supplemental Indenture to the Existing Indenture, which will give effect to the Proposed Amendments to the Existing Notes, that will be effective upon execution but will only become operative upon consummation of the Exchange Offer on the Early Settlement Date.

The Company will not receive any cash proceeds from the issuance of the New Notes in the Exchange Offer and the Solicitation. Existing Notes surrendered in connection with the Exchange Offer, and accepted for exchange, will be cancelled.

The Exchange Offer is made, and the New Notes will be offered and issued, only (a) in the United States to holders of Existing Notes who are reasonably believed to be “qualified institutional buyers” (as defined in Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”)) in reliance upon the exemption from the registration requirements of the Securities Act, and (b) outside the United States to holders of Existing Notes who are persons other than “U.S. persons” (as defined in Rule 902 under the Securities Act) in reliance upon Regulation S under the Securities Act and who are non-U.S. qualified offerees and eligible purchasers in other jurisdictions as set forth in the Exchange Offer Memorandum. Holders who have returned a duly completed eligibility letter certifying that they are within one of the categories described in the immediately preceding sentences are authorized to receive and review the Exchange Offer Memorandum and to participate in the Exchange Offer and the Solicitation (such holders, “Eligible Holders”).

This press release does not constitute an offer to buy or the solicitation of an offer to sell the Existing Notes in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such jurisdiction. This press release does not constitute an offer to sell or the solicitation of an offer to buy the New Notes, nor shall there be any sale of the New Notes in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such jurisdiction. The New Notes will not be registered under the Securities Act or the securities laws of any state and may not be offered or sold in the United States absent registration or an exemption from the registration requirements of the Securities Act and applicable state securities laws.

The Exchange Offer is made, and the New Notes will be offered and issued in Canada on a private placement basis to holders of Existing Notes who are “accredited investors” and “permitted clients,” each as defined under applicable Canadian provincial securities laws.

None of the Company, the dealer managers, the trustee, any agent or any affiliate of any of them makes any recommendation as to whether Eligible Holders should tender or refrain from tendering all or any portion of the principal amount of such Eligible Holder’s Existing Notes for New Notes in the Exchange Offer or Consent to any of the Proposed Amendments to the Existing Indenture in the Solicitation. Eligible Holders will need to make their own decision as to whether to tender Existing Notes in the Exchange Offer and participate in the Solicitation and, if so, the principal amount of Existing Notes to tender.

This press release is being issued pursuant to and in accordance with Rule 135c under the Securities Act.
