Leading Proxy Advisory Firms, ISS and Glass Lewis, Support Pan American Silver's Proposed Acquisition to Create the World's Premier Silver Mining Company

VANCOUVER, Dec. 21, 2018 /CNW/ - Pan American Silver Corp. (NASDAQ: PAAS) (TSX: PAAS) ("Pan American") is pleased to report that, in respect of the upcoming special meeting of Pan American's shareholders, Institutional Shareholder Services Inc. ("ISS") and Glass Lewis & Co. ("Glass Lewis") have each recommended that shareholders vote in favour of the Authorized Capital Resolution and the Share Issuance Resolution in connection to the proposed plan of arrangement (the "Arrangement") pursuant to which Pan American will acquire Tahoe Resources Inc. ("Tahoe"). ISS and Glass Lewis are two leading independent proxy advisory firms who make voting recommendations to their subscribers, including institutional investors.

"We are pleased to receive the positive recommendations from ISS and Glass Lewis, which reaffirm our strategic rationale for the Arrangement and the resulting benefits to shareholders," said Michael Steinmann, President Chief Executive Officer of Pan American. "We would like to thank all shareholders for their support in creating the world's premier silver mining company."

Recommendation to Pan American Shareholders

In reaching its conclusion, ISS noted that: "The Arrangement makes strategic sense as the acquisition of Tahoe and its Escobal Mine is expected to, upon restart of production, increase Pan American's silver production by approximately 80 percent, and give the company the largest silver reserves base and estimated highest gross margins of its peer group."

Glass Lewis noted in its report: "In our view, the merger represents a compelling opportunity to solidify Pan American's position as a leading silver company with an unrivaled collection of assets, best-in-class operational and financial metrics, and an experienced management team. Further, we believe the structure and terms of the transaction represent a reasonable price to pay given the expected strategic and financial benefits and the opportunity to enhance shareholder value."
