LIMA, Peru, May 12, 2025 /CNW/ - Alpayana S.A.C. ("Alpayana") is pleased to announce the successful all-cash offer (the "Offer") to purchase the issued and outstanding common shares (the "Sierra Shares") of Sierra Metals Inc. ("Sierra") for C$1.15 in cash per share. As of the expiry of the initial deposit period for the Offer at 5:00 p.m. (Toronto time) on May 12, 2025 (the "Initial Expiry Time"), 152,904,401 Sierra Shares, representing approximately 70.74% of the issued and outstanding Sierra Shares, were tendered pursuant to the Offer and not withdrawn prior to the Initial Expiry Time.

"We look forward to welcoming the Sierra employees to the Alpayana team and we thank all Sierra Stakeholders for their dedication to this transaction. We look forward to working with the Board and Senior Management in the transition and integration. I would also like to thank the Alpayana team including LXG Capital, McCarthy Tetrault, Rebaza, Alcázar & De Las Casas and Shorecrest for their expertise and execution of this transaction" said Fernando Arrieta, CEO of Alpayana. 

Prior to the Initial Expiry Time, Alpayana agreed to waive all remaining unsatisfied conditions to the Offer, which are further detailed in the offer to purchase and take-over bid circular dated December 30, 2024 (as amended) filed under Sierra's SEDAR+ profile at www.sedarplus.ca and at www.sierrametalscashoffer.com.

As each of the conditions to the Offer were satisfied or waived as of the Initial Expiry Time (including the statutory minimum tender condition being satisfied), in accordance with the terms of the Offer, Alpayana's wholly-owned Canadian subsidiary ("Alpayana Canada" or the "Offeror"), will immediately take-up the Sierra Shares that have been tendered to date and Alpayana will pay for such Sierra Shares as soon as possible and, in any event within three business days. Once the Offeror has taken up the Sierra Shares tendered, Alpayana will own 70.74% of the issued and outstanding Sierra Shares.

As required by applicable Canadian securities laws, Alpayana has extended the expiry time of the Offer by a mandatory period of 10 days to 5:00 p.m. (Toronto time) on May 23, 2025 (the "Expiry Time") in order to allow the remaining minority shareholders to tender their Sierra Shares to the Offer. No further extensions are contemplated at this time. Sierra shareholders who tender their Sierra Shares prior to the Expiry Time will receive the same consideration per Sierra Share to be received by shareholders whose Sierra Shares were deposited and not withdrawn under the Offer prior to the Initial Expiry Time. On May 16, 2025 (the "Second Take-Up Date"), the Offeror intends to take-up any Sierra Shares deposited after the Initial Expiry Time and prior to the Second Take-Up Date. Any Sierra Shares tendered to the Offer on or after the Second Take-Up Date will be taken-up immediately following the Expiry Time. In each case, Alpayana will pay for such Sierra Shares as soon as possible following take-up.

NEXT STEPS

Following the Expiry Time, 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. In accordance with Peruvian securities laws, Alpayana will also launch a local public tender for the number of issued and outstanding shares of Corona that are required to be acquired under Peruvian securities laws, at the price to be established in accordance with such regulations. Remaining shareholders are encouraged to tender their Sierra Shares to the Offer prior to the Expiry Time so that they may promptly receive the offer price of C$1.15 in cash per Sierra Share and not wait until the privatization of Sierra is completed. Shareholders who hold their Sierra Shares through a financial intermediary or broker should be aware that their intermediary may have an earlier deadline to tender. It is recommended that you contact your intermediary promptly in advance of the Expiry Time if you wish to tender Sierra Shares to the Offer. If the privatization of Sierra cannot be completed, remaining shareholders will hold a minority position in a company with limited liquidity.
