Coeur Mining, Inc. Announces Early Participation Deadline Results of Previously Announced Exchange Offer and Consent Solicitation for New Gold Senior Notes

Coeur Mining, Inc. ("Coeur" or the "Company") ((NYSE, TSX:CDE) today announced the early participation results of its previously announced private exchange offer to certain Eligible Holders (the "Exchange Offer") for any and all of the US$400,000,000 aggregate principal amount outstanding 6.875% Senior Notes due 2032 (CUSIP: 644535 AJ5 / C62944 AE0; ISIN: US644535AJ57 / USC62944AE04) (the "Existing Notes") issued by New Gold Inc. ("New Gold") for up to US$400,000,000 aggregate principal amount of new notes to be issued by Coeur (the "New Notes") and cash.

In conjunction with the Exchange Offer, Coeur is soliciting consents (the "Consent Solicitation") to adopt certain proposed amendments to the indenture governing the Existing Notes (the "Existing Notes Indenture") to, among other things, eliminate from the Existing Notes Indenture (i) substantially all of the restrictive covenants and (ii) certain of the events which may lead to an "Event of Default" thereunder (collectively, the "Proposed Amendments").

The following table sets forth certain terms and early results of the Exchange Offer as of 5:00 p.m., New York City time, on April 3, 2026 (the "Early Participation Date"), according to information provided by Global Bondholder Services Corporation, the information agent and exchange agent for the Exchange Offer:

Since the Company has received the requisite consents from Eligible Holders of Existing Notes that, in the aggregate, represent not less than a majority in principal amount of the Existing Notes outstanding from Eligible Holders to effect the Proposed Amendments, the Company has executed a supplemental indenture to effect the Proposed Amendments (the "Supplemental Indenture"), which became effective upon execution but will only become operative upon consummation of the Exchange Offer on the Settlement Date.

As previously announced, Coeur completed the acquisition of all of the issued and outstanding shares of New Gold (the "Transaction"), which constituted a "change of control" under the Existing Notes Indenture. However, since the Supplemental Indenture was executed and the Proposed Amendments became effective, Coeur and New Gold are no longer obliged to make any offer to repurchase the Existing Notes due to the change of control.

The Exchange Offer and Consent Solicitation are being made pursuant to the terms and subject to the conditions set forth in the exchange offer memorandum and consent solicitation statement dated March 23, 2026 (as the same may be amended or supplemented from time to time, the "Exchange Offer Memorandum"). Withdrawal rights expired at 5:00 p.m., New York City time, on April 3, 2026 and have not been extended. Existing Notes validly tendered, and consents validly submitted, may no longer be withdrawn or revoked, except as required by applicable law.

Eligible Holders of Existing Notes who validly tendered and did not validly withdraw their Existing Notes at or prior to the Early Participation Date are eligible to receive on the Settlement Date, for each US$1,000 principal amount of Existing Notes the total consideration set out in the table above (the "Total Consideration"), which includes early participation cash consideration of US$2.00 in cash (the "Early Participation Cash Consideration") and an early participation premium, payable in additional principal amount of New Notes, of US$50 (the "Early Participation Premium"). For the avoidance of doubt, unless the Exchange Offer is amended, in no event will any holder of Existing Notes receive more than US$1,000 aggregate principal amount of New Notes for each US$1,000 aggregate principal amount of Existing Notes accepted for exchange.

The Exchange Offer will expire at 5:00 p.m., New York City time, on April 20, 2026, unless extended or early terminated by Coeur, at its sole discretion (such date and time, as may be extended, the "Expiration Date"). The settlement date for all Existing Notes validly tendered at or prior to the Expiration Date will be promptly after the Expiration Date (such date, the "Settlement Date"). The Settlement Date is currently expected to occur no earlier than the second business day after the Expiration Date, on or about April 22, 2026, unless extended or terminated by Coeur, subject to customary closing conditions, including regulatory approvals.

For each US$1,000 principal amount of Existing Notes validly tendered and not validly withdrawn after the Early Participation Date and on or prior to the Expiration Date, Eligible Holders of Existing Notes will be eligible to receive US$950 principal amount of New Notes (the "Exchange Consideration"). To be eligible to receive the Exchange Consideration, Eligible Holders must validly tender (and not validly withdraw) their Existing Notes at or prior to the Expiration Date.

No accrued and unpaid interest is payable upon exchange of any Existing Notes in the Exchange Offer and Consent Solicitation. The interest rate, interest payment dates, maturity and redemption terms of the New Notes to be issued by Coeur in the Exchange Offer will be the same as those of the Existing Notes to be exchanged. The first interest payment on the New Notes will include the accrued and unpaid interest from the date of the last interest payment made under the Existing Notes Indenture on the Existing Notes in exchange therefor so that a tendering Eligible Holder will receive the same interest payment it would have received had its Existing Notes not been tendered in the Exchange Offer and Consent Solicitation; provided that the amount of accrued and unpaid interest shall only be equal to the accrued and unpaid interest on the principal amount of Existing Notes equal to the aggregate principal amount of New Notes an Eligible Holder receives, which may be less than the principal amount of corresponding Existing Notes tendered for exchange if such holder tenders (and does not subsequently withdraw) its Existing Notes after the Early Participation Date.

The Exchange Offer is subject to the satisfaction or waiver of a number of conditions as set forth in the Exchange Offer Memorandum. The Company reserves its right to amend, extend or terminate the Exchange Offer in its sole discretion and subject to applicable law.

RBC Capital Markets, LLC is acting as the Dealer Manager for the Exchange Offer. The information agent and exchange agent is Global Bondholder Services Corporation. Copies of the Exchange Offer Memorandum, the notice of delivery and related exchange offering materials are available by contacting Global Bondholder Services Corporation at (855) 654-2015 or by email at [email protected].

Documents relating to the Exchange Offer and Consent Solicitation will only be distributed to holders of Existing Notes who complete and return an eligibility certificate, available at https://gbsc-usa.com/eligibility/coeur, confirming that they are either a "qualified institutional buyer" under Rule 144A or not a "U.S. person" and outside the United States under Regulation S for purposes of applicable securities laws, and a non-U.S. qualified offeree (as defined in the Exchange Offer Memorandum) (such holders, the "Eligible Holders"). Additionally, in order to participate in the Exchange Offer and Consent Solicitation, Eligible Holders located or resident in Canada are required to complete, sign and submit to the information agent and exchange agent a Canadian eligibility certification (the "Canadian Eligibility Form"), which is available from the information agent and exchange agent.

None of the Company, the Dealer Manager, the Exchange Agent and Information Agent, or the Trustee for the Existing Notes, or any of their respective affiliates, is making any recommendation as to whether Eligible Holders of the Existing Notes should exchange any Existing Notes in response to the Exchange Offer. Holders of the Existing Notes must make their own decision as to whether to exchange any of their Existing Notes and, if so, the principal amount of Existing Notes to exchange. This announcement of the early participation results of the Exchange Offer is for informational purposes only and does not constitute an offer to sell or the solicitation of an offer to buy any security and shall not constitute an offer, solicitation or sale in any jurisdiction in which such offering, solicitation or sale would be unlawful. The Exchange Offer is being made solely by means of the Exchange Offer Memorandum. In those jurisdictions where the securities, blue sky or other laws require any exchange offer to be made by a licensed broker or dealer, the Exchange Offer is deemed to be made on behalf of the Company by the Dealer Manager or one or more registered brokers or dealers licensed under the laws of such jurisdiction.

The New Notes offered in the Exchange Offer have not been registered under the Securities Act of 1933, as amended (the "Securities Act"), or any state securities laws. Therefore, the New Notes may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act, and any applicable state securities laws.
