• Green360 signed a binding Supply agreement for MKX with Eifers Civil, delivered near Melbourne Airport.
  • Eifers may buy up to 4,800 tonnes over 12 months at a fixed A$250 per tonne delivered, equating to about $1.2 million at the maximum volume.
  • Together with an existing Holcim agreement, the contracts cover up to 9,600 tonnes, 32 per cent of the company's 30,000-tonne-per-annum market creation target.

The agreement

Green360 Technologies Limited (ASX:GT3) announced on 15 October 2026 that it has signed a binding supply agreement with Eifers Civil Pty Ltd for MKX, its proprietary metakaolin supplementary cementitious material. The supply will be made by the company's subsidiary, Suvo Minerals Australia Pty Ltd, and delivered to Eifers' Facility near Melbourne Airport.

The initial supply period is 12 months. The company says Eifers may buy up to 4,800 tonnes over that period, at a fixed price of A$250 per tonne delivered. At the maximum volume, that equates to $1.2 million, which matches the company's estimate of approximately $1.2 million of Revenue for the initial 12 months if Eifers buys the maximum quantity.

Volumes and the larger target

The company says the Eifers agreement, together with an existing agreement with Holcim, covers up to 9,600 tonnes, equal to 32 per cent of its 30,000-tonne-per-annum market creation target linked to Calix. The announcement does not describe the Holcim agreement's terms in the sections reviewed, so how much of that 9,600 tonnes is secured by each contract is not broken out beyond the 4,800 tonnes attributed to Eifers.

Up to 4,800 tonnes over the initial 12 months is equivalent to up to 4,800 tonnes per annum for that one-year term. The announcement refers to MKC-CC (calcined clay) in its commercial terms, whereas MKX-CC is used elsewhere; that product naming difference is in the company's own document.

The product

According to the company, MKX is a metakaolin supplementary cementitious material that can replace up to 40 per cent of Portland cement in concrete. Green360 describes itself as an Australian building materials company supplying kaolin products to customers in the concrete, paint, paper, adhesives, pharmaceuticals and cosmetics industries. It states that it was the first company to commercialise metakaolin as a supplementary cementitious material in the Australian concrete market.

Kaolin from the company's Pittong operations is calcined at Calix Limited's Bacchus Marsh facility, where the company says it has access to up to 30,000 tonnes per annum of calcining capacity.

Commercial implications

The contract is the company's second disclosed MKX supply arrangement in the announcement, following the Holcim agreement, and the company positions both as steps towards building a market for the product in Australian concrete.

The estimated revenue is a maximum, not a guarantee. The company says the $1.2 million figure assumes the full 4,800 tonnes are supplied, and actual sales will depend on the volumes Eifers orders and the company delivers. The announcement describes the agreement as binding, subject to technical compliance standards and industry-standard termination rights. It does not state any conditions precedent, and it does not specify timing for deliveries beyond the initial 12-month supply period.

The announcement does not provide cost, Margin or profit information for the contract, so the effect on Earnings cannot be assessed from the documents. It also does not say whether the contract's revenue is already included in any earlier company forecast.

Risks and what remains unconfirmed

Several points remain open. The company describes the Volume as a maximum. Technical compliance standards and industry-standard termination rights are part of the agreement, and the company has not said how they might affect volumes. The announcement says Eifers has already used the product, but does not specify a minimum purchase quantity or how deliveries under this agreement will be phased across the 12 months.

For investors tracking the company, the next confirmable steps would be orders and deliveries under the agreement and any later disclosure of sales volumes; the announcement gives no dated schedule for these.
