Mallesons has advised Dyno Nobel Limited (ASX: DNL), an ASX-listed explosives and mining services company, on the completion of the sale of its Phosphate Hill fertiliser business to Ryowa II GPS Pty Ltd, a wholly owned subsidiary of Mayfair Australia Corporation.
Completed on 30 June 2026, the sale concludes Dyno Nobel’s separation from fertilisers and marks a significant milestone in its transformation into a pure play global explosives business.
Phosphate Hill is a strategically important Australian fertiliser manufacturing facility, supporting domestic fertiliser supply and approximately 540 jobs in North-West Queensland.
The transaction involved $1 nominal consideration, with Ryowa assuming economic risk and benefit from 1 April 2026 and operational and environmental liabilities from completion. Dyno Nobel made a $50 million completion payment, will fund $125.9 million for site rehabilitation, and may receive up to $150 million in deferred consideration.
The Mallesons team was led by Partner Adam Black, with supported Partners Craig Rogers, Emily Heffernan, Senior Associate Sam Dimopoulos and Solicitor Matt Dean.
Commenting on the transaction, Adam Black said:
“The completion of the Phosphate Hill sale is an important milestone. It enables Dyno Nobel to move forward as a focused global explosives business, while supporting the continuity of an asset that is strategically important to Australian agriculture, domestic fertiliser security and the North-West Queensland community.”
Mallesons has supported Dyno Nobel throughout this multi-year transformation, advising on the divestment of its Fertilisers Distribution business, Perdaman Offtake Agreement and Phosphate Hill assets.
