MOTA-ENGIL INFORMS ABOUT A NEW CONTRACT IN THE REPUBLIC OF ARMENIA WORTH AROUND 700 MILLION USD

MOTA-ENGIL S.G.P.S., S.A. (MOTA-ENGIL) hereby announces that its subsidiary, MOTA-ENGIL MINING CAUCASUS LLC, has entered into a contract mining services agreement with Lydian Armenia CJSC, with a total value of approximately USD 700 million (equivalent to approximately 614 million euros).

This contract, with an estimated duration of 72 months, involves the execution of a comprehensive scope of industrial engineering services for the Amulsar Gold Mine project, located approximately 10 km from the city of Jermuk and 170 km southeast of Yerevan, the capital of Armenia.

Lydian Armenia CJSC is the entity responsible for developing the Amulsar Gold Mine, one of the most significant mining projects in the Caucasus region. The company is 87.5% owned by United Gold, a privately held mining company with a clear strategy of sustainable growth through the acquisition, development, and operation of high-quality gold assets in emerging markets, and 12.5% owned by the Government of Armenia, underlining the project's institutional alignment and strategic importance.

United Gold is led by a highly experienced management team that previously founded and developed Allied Gold Corporation, one of Africa's largest gold producers, currently listed on both the Toronto and New York Stock Exchanges. The team has a proven track record in the acquisition, development, and optimization of mining projects across multiple continents.

The award of this project represents another strategic milestone for MOTA-ENGIL, reinforcing its position as an international benchmark in industrial engineering applied to mining. This contract not only highlights the technical expertise and execution capabilities of MOTA-ENGIL in this sector but also contributes significantly to the expansion of its backlog.

This new challenge reflects the Group's continued commitment to international expansion, market diversification, and the creation of sustainable value for its shareholders.
