On March 20,2026 (the “Closing Date”), pursuant to the terms and conditions set forth in the Arrangement Agreement, Coeur (through the Canadian Sub) acquired all of the issued and outstanding common shares of New Gold (each, a “New Gold Common Share”) pursuant to a Plan of Arrangement with New Gold becoming a wholly-owned subsidiary of Coeur.

The foregoing descriptions of the Arrangement and Arrangement Agreement do not purport to be complete and are qualified in their entirety by reference to the full text of the Arrangement Agreement, which is included as Exhibit 2.1 to the Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) by Coeur on November 3, 2025 and is incorporated by reference herein.

On March 20,2026, Coeur entered into a Credit Agreement (the “Credit Agreement”) by and among Coeur, as borrower, certain subsidiaries of Coeur, as guarantors, the lenders party thereto and National Bank of Canada, as administrative agent. The Credit Agreement replaced Coeur’s existing credit agreement dated as of September 29, 2017, by and among Coeur, as borrower, certain subsidiaries of Coeur, as guarantors, the lenders party thereto, and Bank of America, N.A., as administrative agent, as amended.

The Credit Agreement provides for a$1,000,000,000 senior secured revolving credit facility (the “Facility”), which may be increased by up to$250,000,000 in incremental loans and commitments subject to the terms of the Credit Agreement. The proceeds of the Facility will be used to finance working capital and general corporate purposes of Coeur and its subsidiaries.

The Facility has a term offive years. The loans under the Facility will bear interest at a rate equal to either a base rate plus a margin ranging from 0.450% to 1.500%, Term SOFR plus a margin ranging from 1.450% to 2.500%, or Daily Simple SOFR plus a margin ranging from 1.450% to 2.500%, in each case as selected by Coeur, with such margin determined in accordance with a pricing grid based upon Coeur’s consolidated net leverage ratio as of the end of the applicable period. Subject to no event of default, upon Coeur receiving at leasttwo of the following debt ratings: BBB- (or better) from S&P, Baa3 (or better) from Moody’s, or BBB- (or better) from Fitch (the “Collateral Release Event”) and theone-time election of Coeur (the “Margin Election”), the applicable margin will instead be determined based upon Coeur’s debt ratings from S&P, Moody’s and Fitch, and will range from 0.125% to 1.000% for Base Rate Loans and from 1.125% to 2.000% for Term SOFR Loans and Daily SOFR Loans.

Coeur is required to pay a commitment fee on thedaily unused portion of the Facility. Prior to the Collateral Release Event and the Margin Election, the commitment fee ranges from 0.200% to 0.350%per annum, determined in accordance with a pricing grid based upon Coeur’s consolidated net leverage ratio. Following the Collateral Release Event and the Margin Election, the commitment fee ranges from 0.110% to 0.250%per annum, determined in accordance with a pricing grid based upon Coeur’s debt ratings. Coeur will also pay customary letter of credit fees and other fees under the Credit Agreement.

Voluntary prepayments of the loans under the Credit Agreement are permitted without premium or penalty. Other than a requirement that Coeur prepay outstanding loans and/or cash collateralize letter of credit obligations to the extent that the total revolving outstandings exceed the aggregate revolving commitments then in effect, the Credit Agreement does not require mandatory prepayments of the loans prior to maturity. Amounts repaid may be subsequently reborrowed subject to the terms of the Credit Agreement.

The Facility is secured by a pledge of the shares of certain of Coeur’s domestic and Canadian subsidiaries. Upon the occurrence of the Collateral Release Event, and provided no event of default has occurred and is continuing, the equity pledge will be released and the Facility will be unsecured.

The Credit Agreement contains representations and warranties and affirmative and negative covenants that are usual and customary, including representations, warranties, and covenants that, among other things, restrict the ability of Coeur and its subsidiaries to incur additional debt, incur or permit liens on assets, make investments and acquisitions, consolidate or merge with any other company, engage in asset sales and make dividends and distributions. The Credit Agreement also contains representations, warranties, and covenants that, among other things, require compliance with environmental laws and maintenance of mining rights. The Credit Agreement also contains financial covenants consisting of (i) prior to the Collateral Release Event and the Margin Election, a consolidated net leverage ratio not to exceed 3.50 to 1.00 and a consolidated interest coverage ratio of not less than 3.00 to 1.00, and (ii) following the Collateral Release Event and the Margin Election, a net debt to capital ratio not to exceed 60%.

Obligations under the Credit Agreement may be accelerated upon the occurrence of certain customary events of default (subject to grace periods and cure rights, as appropriate), including among others: nonpayment of principal, interest or fees; breach of the affirmative, negative or financial covenants; breach of the representations or warranties in any material respect; events of default with respect to other material indebtedness; bankruptcy or insolvency; material judgments entered against Coeur or any of its restricted subsidiaries that are not promptly paid or stayed; termination of or default under any material contract or license relating to the New Afton Mine, the Rainy River Mine, the Las Chispas Mine, the Palmarejo Mine, the Rochester Mine, the Kensington Mine, or the Wharf Mine that could reasonably be expected to result in a material adverse effect; invalidity or unenforceability of the Credit Agreement or other documents associated with the Credit Agreement; and a change of control of Coeur.
