VANCOUVER, British Columbia, Aug. 18, 2025 (GLOBE NEWSWIRE) -- MAG Silver Corp. (NYSE:MAG) ("MAG", or the "Company") announces today that, other than Mexican competition approval ("COFECE Approval"), all required key approvals and authorizations to consummate the Arrangement have been obtained, including the approval of MAG shareholders, the final order of the Supreme Court of British Columbia, Canadian competition approval, and the conditional approval of the Toronto Stock Exchange and the New York Stock Exchange. As such, registered holders of common shares of the Company ("MAG Shares") must indicate their election by no later than 2:00 p.m. (Vancouver time) on August 27, 2025 (the "Election Deadline"), to receive either:

(i) $20.54 in cash for each MAG Share held (the "Cash Consideration"); or

(ii) $0.0001 in cash and 0.755 of a common share (each whole share, a "Pan American Share") of Pan American Silver Corp. ("Pan American") for each MAG Share held (the "Share Consideration" and, together with the Cash Consideration, the "Consideration"),

in each case, subject to proration in connection with the previously announced plan of arrangement whereby Pan American will acquire all of the issued and outstanding MAG Shares (the "Arrangement").

Election Deadline

Registered holders of MAG Shares may make an effective election by depositing a properly completed and duly executed letter of transmittal and election form (the "Letter of Transmittal and Election Form") indicating their election to receive the Cash Consideration or the Share Consideration, together with the certificates (if applicable) representing their MAG Shares and all other documentation required by Computershare Investor Services Inc. (the "Depositary"), before the Election Deadline with the Depositary. The Letter of Transmittal and Election Form is available under the Company's SEDAR+ profile at www.sedarplus.ca and on the Company's website at https://magsilver.com/investors/#pan-american-meeting.

Non-registered holders of MAG Shares that hold their MAG Shares through a broker, investment dealer or other intermediary should carefully follow the instructions and deadlines from the intermediary that holds such MAG Shares on their behalf and should contact such intermediary for instructions and assistance in making an election or with any questions about their election. Non-registered holders of MAG Shares who may have made an election through an intermediary prior to the date of this news release may wish to contact their intermediary prior to the Election Deadline to verify that their election has been made properly.

Any holder of MAG Shares who fails to make a proper election in respect of their MAG Shares prior to the Election Deadline, or who chooses not to make an election, will be deemed to have elected to receive, for each MAG Share held by such person, the Share Consideration, subject to proration. The Cash Consideration and the Share Consideration are each subject to proration provisions, such that the aggregate consideration paid to all MAG shareholders will consist of $500 million in cash and the remaining Consideration paid in Pan American Shares. Accordingly, a MAG shareholder may receive both cash and Pan American Shares in exchange for MAG Shares, regardless of such holder's election to receive the Cash Consideration or the Share Consideration. All elections and deposits made under the Letter of Transmittal and Election Form are irrevocable.

The election available in respect of the Cash Consideration or the Share Consideration is an investment decision which carries tax consequences. Holders of MAG Shares should consult their investment and tax advisors prior to making their election.

Additional information regarding the Arrangement and the procedure for the exchange of MAG Shares for the Consideration is provided in the Company's management information circular dated June 6, 2025 (the "Circular"). The Circular is available under the Company's SEDAR+ profile at www.sedarplus.ca and on the Company's website at https://magsilver.com/investors/#pan-american-meeting.

If the COFECE Approval is obtained and all closing conditions are satisfied or waived, the Arrangement is expected to be completed in the third quarter of 2025. Following completion of the Arrangement, the MAG Shares are expected to be delisted from the Toronto Stock Exchange and NYSE American LLC. An application is also expected to be made for MAG to cease to be a reporting issuer in the applicable jurisdictions following closing of the Arrangement.
