Announcement PDF Green360 Technologies Ltd. ABN 97 140 316 463 Head Office: Level 1, 105 St Georges Tce, Perth, Western Australia 6000 Operations: 3610 Glenelg Highway, Pittong, Victoria 3360 ASX ANNOUNCEMENT 15 October 2026 G360 Secures Binding MKX Supply Agreement with Eifers Civil • Binding agreement to supply Eifers Civil with up to 4,800 tonnes of MKX-CC over an initial 12- month period, at A$250 per tonne delivered. • Together with Holcim, supply agreements, cover up to 9,600 tonnes across their respective initial 12 month terms, equivalent to 32% of G360’s 30,000-tonne-per-annum Calix market creation target1. • Agreement follows Eifers’ use of MKX in major infrastructure projects, including airport taxiway pavement pours. • Over 3,500 cubic metres of concrete containing MKX has now been poured in Melbourne Infrastructure projects2 • This market-creation phase is occurring as the Australian concrete industry prepares for increasing structural constraints in traditional supplementary cementitious material (SCM) supply, including fly ash and blast furnace slag. Green360 Technologies Limited (ASX:GT3) (“GT3” “G360” or “the Company”) is pleased to announce that it has entered into a binding supply agreement with Eifers Civil Pty Ltd (“Eifers”) for the supply of MKX, the Company’s proprietary metakaolin supplementary cementitious material. The agreement covers up to 4,800 tonnes of MKX over an initial 12-month period at a fixed price of A$250 per tonne delivered. Eifers has already incorporated MKX into concrete used in major infrastructure projects, including recently completed airport taxiway pavement pours. The agreement builds on this experience and follows G360’s previously announced binding supply agreement with global materials company Holcim4. G360 Executive Chairman Aaron Banks said: “Securing Eifers as our second commercial supply customer builds on the practical experience gained using MKX in infrastructure projects. It is an important step in establishing repeat demand for a locally produced alternative to traditional SCMs. “As supplies of fly ash and slag become increasingly constrained, concrete producers are looking for alternatives that can work within their existing operations. Our production arrangement with Calix allows us to supply customers now and build the market ahead of investment in dedicated production. “Our focus is on securing additional customers and growing sales, supported by the scoping study we expect to release this quarter on purpose-built MKX production facilities. Eifers Concrete Managing Director Dan Eifermann said: “We’re excited to strengthen our partnership with G360 and take another significant step towards the next generation of sustainable concrete in Australia. At Eifers, we’re committed to leading the adoption of innovative, high-quality supplementary cementitious materials that deliver genuine reductions in embodied carbon without compromising performance, quality or constructability. Having already successfully incorporated MKX into concrete supplied to major Level Crossing Removal Projects and completed airport pavement trials, we’ve demonstrated its potential in demanding infrastructure applications. We’re also progressing trials incorporating MKX into our Ecofil lightweight cellular concrete range, opening up further opportunities for sustainable construction solutions. This agreement provides Eifers with access to a locally produced, high-quality SCM and puts us in a strong position to expand our low-carbon concrete offering across major infrastructure and commercial projects. We see calcined clay playing an increasingly important role in the future of Australian concrete, and we intend to be at the forefront of that transition.” Eifers concrete incorporating G360’s MKX calcined clay at Melbourne Airport Business Park, Level Crossing Removal Project and a trial pavement pour at Melbourne Airport. Material commercial terms Under the binding agreement, G360’s subsidiary Suvo Minerals Australia Pty Ltd will supply up to 4,800 tonnes per annum of MKC-CC (Calcined Clay) delivered to Eifer’s facility near Melbourne Airport. The Agreement is based on a fixed price of $250 per tonne and contains technical compliance standards. The Company estimates the value of the contract to generate approximately $1.2 million of revenue for the initial 12 month supply period should Eifer’s purchase the maximum quantity of product under the Agreement. The Agreement is binding on commercial supply terms with industry standard termination rights. The sales value above assumes supply of the full 4,800 tonnes. Actual sales will depend on volumes ordered and delivered under the agreement. MKX market creation and commercialisation G360’s commercialisation strategy is focused on developing the market for MKX ahead of the establishment of larger-scale dedicated production capacity. MKX is G360’s commercially produced metakaolin SCM, developed as an alternative to traditional supplementary cementitious materials including fly ash and blast furnace slag. MKX can replace up to 40% of Portland cement in concrete. Kaolin from G360’s Pittong operations is currently calcined at Calix Limited’s Bacchus Marsh facility, providing access to up to 30,000 tonnes per annum of calcining capacity in close proximity to the Melbourne concrete market. This capacity provides G360 with a platform from which to progressively develop demand, customer relationships, specifications, logistics and real-world application experience before transitioning to larger- scale dedicated production. With more than 3,500m³ of MKX-containing concrete now placed, the market-creation program is generating an increasingly substantial body of real-world experience across infrastructure and civil construction applications. G360 considers this phase important to the Company’s scale-up strategy: develop the market first, establish repeatable demand and industry confidence, and then scale production capacity in response to that market. This approach is intended to progressively de-risk future investment in dedicated production capacity by allowing customer demand, product applications, specifications and supply-chain requirements to be established through real-world commercial use The Company remains focused on increasing commercial volumes through the existing market-creation platform while progressing its longer-term strategy to establish MKX as a large-scale domestic SCM supply option. G360’s strategy is therefore centred on the convergence of two developments: the progressive establishment of MKX through real-world commercial use, and the expected structural tightening in the availability of traditional SCMs. The Company believes this provides an opportunity to develop MKX from an emerging alternative SCM into a material component of Australia’s future concrete supply chain.

About Green360 Technologies Limited Green360 Technologies (ASX:GT3) is an Australian-based building materials supplying Kaolin products to blue chip customers in the concrete, paint, paper, adhesives, pharmaceuticals and cosmetics industry. G360 was the first company to commercialise metakaolin (calcined kaolin) as a supplementary cementitious material (SCM) in the Australian concrete market. The product, known under the platform of MKX, is a low carbon partial cement replacement product which reduces the embodied carbon in concrete, the world’s second largest cause of CO2 emissions. The Australian concrete industry is facing an imminent supply shortage of existing SCMs (predominately fly ash, blast furnace slag and silica fume) and MKX is strategically positioned to replace these products in the market. Our objective is not simply to sell another SCM. It is to help build the next generation supply chain for the concrete industry.
