Major Drilling acquires Australian mine dewatering contractor for A$70m

Major Drilling completed its acquisition of Western Australia-based Bunbury Drilling Company through its Australian subsidiary for A$50 million upfront, plus an earn-out of up to A$20 million over three years (up to approximately C$69 million total). BDC reported approximately A$43 million in revenue and A$15 million in adjusted EBITDA for the 12 months ended June 30, 2026; the full earn-out requires average annual EBITDA of approximately A$18 million over the earn-out period. Major Drilling will fund the upfront payment from existing cash and debt facilities, and BDC’s management team will remain in place.

Analysis

MDI: modestly constructive, but not a standalone catalyst. The deal adds a specialized service line that may be less dependent on exploration-drilling budgets: mine dewatering is linked to operating-mine water management. That could diversify MDI’s activity mix and deepen relationships with established Western Australian producers, though the article provides no contract-duration or customer-concentration data to establish how recurring the earnings are.

On reported EBITDA, the A$50m upfront payment is roughly 3.3x trailing EBITDA; maximum consideration is about 4.7x. Those are attractive-looking entry multiples only if EBITDA is maintainable and do not account for capex, working capital, or integration costs. The earn-out shifts some execution risk to the seller, but its A$18m average EBITDA hurdle implies meaningful growth from the reported base. Cash-and-facility funding also makes the real return dependent on MDI’s existing leverage and financing cost—key missing checks before underwriting accretion.

Horizon: near term, expect limited price impact absent deal-size materiality versus MDI; over 1–3 months, watch for leverage, integration, and guidance details. Over 6–18 months, successful retention of management and earnings delivery could validate a broader move into mine-site services. The contrarian risk is treating a small bolt-on as strategic transformation; eight specialized rigs may constrain scale, while the reported EBITDA could be unusually strong. Thesis weakens if MDI signals higher-than-expected debt, BDC misses the earn-out trajectory, or acquired EBITDA requires materially more capital than implied.

Key Decisions for Investors

• Maintain a modest positive bias on MDI, but do not chase a headline-driven gap; consider adding on weakness once the next disclosure clarifies net debt, financing cost, and the acquisition’s size relative to group earnings.
• Track BDC’s EBITDA, utilization and capex against the earn-out path over the next 1–3 quarters. Treat the reported purchase multiples as provisional until maintenance investment and working-capital needs are known.
• Falsification: reduce the positive bias if MDI raises leverage concerns, cuts group guidance, or indicates BDC’s earnings are below the trajectory needed for the earn-out; also reassess if management retention or customer continuity falters.
• No clean pair trade is established by the available facts. The key alert is whether this becomes repeatable, capital-efficient diversification from more cyclical drilling work rather than an isolated acquisition.
