ALAMOS GOLD ANNOUNCES THE SALE OF ITS TURKISH DEVELOPMENT PROJECTS FOR TOTAL CASH CONSIDERATION OF $470 MILLION

Alamos Gold Inc.'s wholly owned Dutch subsidiaries, Alamos Gold Holdings Cooperatief UA and Alamos Gold Holdings BV, have entered into a definitive agreement to sell Dogu Biga Madencilik Sanayi ve Tic. AS, their wholly owned Turkish subsidiary, which owns the Kirazll, Agl Dagl and Camyurt projects located in northwestern Turkey, to Tumad Madencilik Sanayi ve Ticaret AS, a mining company operating in the Republic of Turkey, for total cash consideration of $470-million. (All amounts are in U.S. dollars, unless otherwise stated.) The purchase price is payable by Tumad to Alamos as follows:

1. $160-million payable upon closing of the transaction;
2. $160-million payable on the one-year anniversary of the closing of the transaction; and
3. $150-million payable on the two-year anniversary of the closing of the transaction.

Each of the second and third instalment payments is secured by a bank guarantee provided by international financial institutions with investment-grade ratings, ensuring total guaranteed proceeds to Alamos of $470-million within two years of closing of the transaction.

"This transaction marks a positive outcome, allowing us to crystallize significant value for our Turkish assets and utilize the proceeds to support the development of our portfolio of other high-return growth projects. These projects are all located in North America, they are all lower cost and they underpin one of the strongest growth profiles in our sector," said John A. McCluskey, president and chief executive officer of Alamos.

In addition to supporting the development of its pipeline of growth projects, including the phase 3-plus expansion within the Island gold district, the Lynn Lake project and the Puerto Del Aire project in Mexico, Alamos expects to use the proceeds from the transaction to reduce existing debt obligations.

The transaction is expected to close in the fourth quarter of 2025, and is subject to customary closing conditions for a transaction of this nature and receipt of regulatory approval in Turkey.

In conjunction with the transaction, the Dutch subsidiaries and the Republic of Turkey have agreed that arbitration proceedings brought by the Dutch subsidiaries against the Republic of Turkey under the Netherlands-Turkey Bilateral Investment Treaty shall remain suspended, and will be discontinued with prejudice after certain contractual milestones are reached. The arbitration proceedings remain confidential, and, therefore, at this stage, it is not possible to disclose further details concerning those proceedings.
