STRACON GROUP HOLDING AWARDED INTEGRATED ENGINEERING, CONSTRUCTION, FINANCING AND O&M CONTRACT FOR PEREZ CALDERA MINING INFRASTRUCTURE PROJECT

Stracon Group Holding Inc. has been awarded a significant integrated engineering, construction, financing, and long-term operations and maintenance (O&M) contract in connection with the Perez Caldera tailings dam, located at the Los Bronces operation in the Lo Barnechea district (Chile).

The contract was awarded by Anglo American Sur S.A. and will be executed by the Stracon Engineering business unit.

Highlights

• Integrated, full life cycle mining infrastructure solution: Demonstrates Stracon's ability to deliver engineering, construction, financing, and long-term operations and maintenance under a single execution framework, consistent with the company's integrated infrastructure strategy.
• Meaningful backlog addition and multiyear revenue visibility: Represents a long-duration infrastructure contract with a high-quality global mining counterparty, resulting in increased consolidated backlog and supporting recurring revenue and cash flow visibility over the contract term.

This contract supports the initiation of the Perez Caldera tailings dam removal and Water Resource adaptation project, which was environmentally approved by the authority in April, 2025, and aligns with Stracon's strategy of expanding its portfolio of long-duration, infrastructure-led service arrangements that integrate engineering, execution, financing and operations.

"This award reflects continued confidence from a leading global mining company in Stracon's ability to deliver complex infrastructure solutions across the full asset life cycle," said Steve Dixon, chief executive officer of Stracon. "Our integrated engineering, EPC, financing and O&M platform enables us to support mining clients from project development through long-term operations, while maintaining a strong focus on safety, execution discipline and sustainable value creation."

Under the agreement, Stracon Engineering will provide full life cycle delivery of dedicated infrastructure assets required to condition, remove and transport tailings material from the Perez Caldera tailings dam.

The project will be executed in accordance with Stracon's established standards for health and safety, environmental management, and operational excellence, leveraging the company's multidisciplinary engineering capabilities, local execution teams and experienced operations personnel throughout the duration of the contract.

The services agreement was entered into in the ordinary course of business.
