Alpayana Announces Final Take-Up of Sierra Shares and Expiry of Offer

LIMA, Peru, May 26, 2025 /CNW/ - Alpayana S.A.C. ("Alpayana") is pleased to announce today that an additional 15,450,178  common shares (the "Sierra Shares") of Sierra Metals Inc. ("Sierra") were validly tendered (and not withdrawn) under its all-cash offer (the "Offer") to purchase all of the issued and outstanding Sierra Shares for C$1.15 in cash per share as of the expiry of the extended deposit period for the Offer at 5:00 p.m. (Toronto time) on May 23, 2025. The Offer has now expired.

These recently deposited Sierra Shares represent approximately 7.15% of the issued and outstanding Sierra Shares. In accordance with the terms of the Offer, Alpayana's wholly-owned Canadian subsidiary ("Alpayana Canada" or the "Offeror"), will immediately take-up the additional 15,450,178 Sierra Shares that have been tendered to the Offer (the "Final Take-Up") and Alpayana will pay for such Sierra Shares as soon as possible.

Alpayana previously acquired 187,318,324 Sierra Shares under the Offer, representing approximately 86.67% of the total number of outstanding Sierra Shares, and, after giving effect to the Final Take-Up, Alpayana will own an aggregate of 202,768,502 Sierra Shares, representing 93.82% of the issued and outstanding Sierra Shares.

Alpayana Canada intends to pursue a subsequent acquisition transaction to complete the privatization of Sierra and acquire all Sierra Shares not acquired pursuant to the Offer. Alpayana intends to requisition a meeting of Sierra shareholders as soon as possible for the purpose of, among other things, seeking shareholder approval of such subsequent acquisition transaction. Following the completion of such subsequent acquisition transaction, Alpayana Canada intends to cause Sierra to apply to the Toronto Stock Exchange (the "TSX") to delist the Sierra Shares from the TSX and, if permitted by applicable law, cause Sierra to cease to be a reporting issuer (or equivalent) under applicable Canadian securities laws. In accordance with Peruvian securities laws, Alpayana will also launch a local public tender for the number of issued and outstanding shares of Sociedad Minera Corona S.A. that are required to be acquired under Peruvian securities laws, at the price to be established in accordance with such regulations.
