Sierra Metals Inc. (TSX: SMT | OTCQX: SMTSF | BVL: SMT) ("Sierra Metals" or the "Company"), Alpayana S.A.C. ("Alpayana") and Alpayana Canada Ltd. ("Alpayana Canada") jointly announce that they have reached an agreement in principle for an all-cash, board supported take-over bid under which Alpayana Canada will make an offer to acquire all of the common shares of the Company ("Common Shares") for cash consideration of CDN $1.15 per Common Share (the "Supported Bid").

The parties expect to enter into a support agreement for the Supported Bid (the "Support Agreement") as soon as reasonably practicable, but in any event, by April 30, 2025. The Support Agreement is expected to contain customary terms for the Supported Bid, including the existing conditions of Alpayana's take-over bid offer.

The Supported Bid has the unanimous support of the Board of Directors and the Special Committee of independent directors of Sierra Metals and the Board of Directors will unanimously recommend that the shareholders of Sierra Metals tender their shares to the Supported Bid. Sierra Metals' financial advisor, BMO Capital Markets, has provided an oral fairness opinion to the Sierra Board that, as of April 22, 2025 and subject to the assumptions, limitations and qualifications on which such opinion is based, the consideration to be received under the Supported Bid is fair, from a financial point of view to the Shareholders of Sierra Metals.

Following the execution of the Support Agreement, the Sierra Board will issue an amended Directors' Circular in connection with the Supported Bid setting forth the details of its recommendation and certain related matters. Alpayana will issue a Notice of Variation in connection with the Supported Bid as well.

In addition, each of the directors and officers of Sierra Metals have agreed to enter into a lock-up agreement with Alpayana under which they will agree to tender their Common Shares to the Supported Bid.

Alpayana Canada has extended the expiry time in respect of the existing take-over bid until 5:00 p.m. (Toronto time) on May 12, 2025, in order to provide the shareholders of Sierra Metals with sufficient time to tender their shares.
