The two plants were sold to an unnamed third-party on February 27 for $19 million.

The buyer is understood to be part of a corporate group with substantial financial resources.

The sale is not subject to a finance condition. It will be funded through the buyer's existing cash reserves.

Under the sale terms MLG had to decommission and transport the plants and related ancillary equipment to the third-party's site for laydown.

MLG completed those tasks for about $2 million, which will be taken off the purchase price.

The company will not be involved in any future commissioning of the plants.

With sale proceeds to be made in instalments, MLG is expecting to get $17 million, after completing final delivery.

MLG founder and managing director Murray Leahy said the team had done a fantastic job in safely and efficiently decommissioning the plants.

"They are large and complex structures which require careful planning and execution to successfully redeploy to alternative sites," he said.

"The proceeds from the sale have and will contribute to further improving MLG's financial position, allowing us to focus on our clients and the large volume of demand we have in front of us."

Leahy also commended the company's operational team for its effort in ensuring a smooth decommissioning process and laydown to the purchaser's site.

He said discussions had been held with a number of parties to determine the best way to either dispose of the assets or establish an appropriate long-term operation for them.

"Given the long lead time and high working capital requirement associated with redeploying the assets, we are very pleased to have secured an outright sale," Leahy said.

"The certainty of this option and the immediate release of capital given the current demand for MLG services and our capital position, is a very good outcome for MLG."
