FY2026 Interim Results Presentation

• Returned to growth and improved margins after navigating FY25 challenges
• Order book increased to $441m, up 79% on prior corresponding period
• Positive outlook with $1 billion pipeline and increased coal prices

Mastermyne Group Ltd reported strong financial results for H1 FY2026, with growth in underlying EBITDA, NPAT, net cash and order book compared to the prior corresponding period. The company returned to growth and improved margins after navigating external challenges in FY2025. Revenue was 7% lower than the prior corresponding period due to ignition events at two mines, but 17% higher than H2 FY2025 with the addition of a new contract. The order book grew to $441m, up 79% on the prior corresponding period, reflecting contract extensions and new work. Mastermyne has a positive outlook, with a $1 billion pipeline and increased coal prices creating favourable market conditions. The company also divested its non-core MyneSight training business and extended its exclusive distribution for critical strata consolidation products. Safety, people and sustainability remain key priorities, with a focus on elevating safety performance, leadership development and sustainability reporting.

FY2026 revenue is expected to be in the range of $220m to $230m, with underlying EBITDA in the range of $17.0m to $18.0m.

Mastermyne expects continued growth underpinned by its $441m order book and $1 billion pipeline. The company is actively pursuing organic and acquisition growth opportunities to further expand and diversify the business.
