• Major $20 million contract awarded for Brigalow Gas Peaking Plant in Queensland
• Comprehensive Balance of Plant electrical infrastructure delivering mission-critical power reliability
• Total FY26 contract awards reach approximately $37 million, demonstrating accelerating market momentum across energy transition sectors

Mayfield Group Holdings Limited (ASX: MYG) ('Mayfield') has announced that its subsidiary, Mayfield Industries, has entered into a contract with GE Power Australia Pty Ltd valued at approximately $20 million to engineer, design, manufacture, factory test and deliver prefabricated Balance of Plant (BOP) electrical modules for the Brigalow Gas Peaking Plant in Queensland. This contract exemplifies Mayfield's unique positioning in Australia's energy infrastructure landscape, as it builds the fundamental electrical infrastructure that ensures reliable and resilient power delivery, the foundation upon which Australia's energy transition depends. The Brigalow Gas Peaking Plant represents critical dispatchable generation capacity supporting Queensland's grid stability as renewable penetration increases. Mayfield's ability to deliver these complex, mission-critical systems reflects its decades of technical expertise and customer relationships. This contract forms part of Queensland's broader energy security strategy, ensuring reliable dispatchable generation capacity that balances intermittent renewable supply and supports grid stability during peak demand periods. Including the Brigalow Gas Peaking Plant, Mayfield has secured approximately $37 million in new contract awards since the beginning of FY26, demonstrating strong market momentum across its core energy transition and critical infrastructure sectors. Mayfield's work in hand now stands at approximately $116 million, providing strong revenue visibility well into FY26 and beyond. The diversity of contracts across energy generation, network infrastructure, renewable energy integration, and energy storage demonstrates the breadth of Mayfield's market opportunity and the strength of its technical capabilities across energy transition applications.

The combined contract value of approximately $37 million will be recognised progressively as project milestones are achieved and is expected to contribute positively to FY26 financial performance.

These awards strengthen Mayfield's order book and position the company well to capitalise on the unprecedented infrastructure investment wave driven by AI and data centre growth, renewable energy deployment, grid modernisation and industrial electrification.
