METLEN Energy & Metals has secured a long-term customer for approximately 25 per cent of the annual gallium production planned at its facility in Greece, establishing a commercial foundation for a project that forms part of the European Union’s efforts to develop domestic supplies of critical materials. The customer is a leading US technology company, but METLEN has not disclosed its identity. The company has also withheld the contracted volume, pricing mechanism, delivery timetable, agreement duration and financial terms.
The commitment nevertheless gives the Greek gallium project a defined industrial outlet before production begins. A long-term offtake agreement covering a significant portion of planned output provides a commercial basis for the development alongside the project’s existing institutional and financial support. The transaction is described as the first major commercial gallium supply agreement between a European producer and a large US technology company. It also expands the potential role of Greece in technology-oriented industrial supply chains beyond its established position in aluminium production.
Gallium supply gains strategic importance
Gallium is used in compound semiconductors, including gallium arsenide and gallium nitride. These materials are incorporated into high-frequency telecommunications, power electronics, radar, advanced defence systems, satellite communications, electric-vehicle charging equipment and renewable-energy infrastructure. Demand is also being supported by the growth of artificial-intelligence data centres, where increasingly advanced communications and power-conversion equipment requires sophisticated semiconductor materials.
The supply chain remains strategically sensitive because China dominates primary gallium production and processing capacity. Gallium is typically recovered as a by-product of alumina and zinc processing rather than produced from dedicated mines, limiting the speed at which alternative sources can be established. Developing new gallium capacity requires suitable feedstock, specialised recovery technology and an industrial processing platform capable of incorporating relatively small quantities of the metal into a much larger metallurgical operation.
Aluminium of Greece provides the industrial base
METLEN can draw on its established Aluminium of Greece complex for the planned operation. The company operates the European Union’s only fully integrated production chain covering bauxite mining, alumina refining and primary aluminium, together with privately controlled port infrastructure.
The proposed gallium production facility will therefore be developed around an existing industrial operation rather than through the construction of a separate mine and processing complex. This integration is particularly relevant because gallium occurs at very low concentrations and is most effectively recovered from process streams generated during alumina refining. METLEN can use existing bauxite supplies, refining infrastructure, utilities, laboratories and technical personnel while adding gallium production to its established metals operation.
The approach also demonstrates how existing European metallurgical assets can contribute to critical-material supply without relying exclusively on new mining developments. Recovering trace elements from materials already passing through industrial facilities requires changes to process flows, specialised recovery systems and the ability to produce material at the purity levels required by technology and defence customers.
Internal research supports gallium recovery
METLEN said the gallium production process was developed through long-term research by its internal technical teams at Aluminium of Greece, working with the newly established Critical & Rare Metals division within M Metals. The material has already undergone extensive qualification testing. Qualification is a significant stage in establishing a new critical-material supply chain because technology customers require evidence that the material meets specifications for purity, consistency and production controls.
The customer commitment therefore covers more than future production capacity. The agreement indicates that the US technology buyer has advanced sufficiently through technical qualification to regard the prospective European supply as commercially acceptable. For critical-material developers, customer qualification can be as important as establishing processing capacity. Production can be technically feasible while still lacking a viable market if the resulting material does not meet customer specifications. Semiconductor supply chains impose particularly demanding requirements because variations in material purity can affect downstream component performance and reliability.
Offtake provides a market base for planned output
The agreement covering one-quarter of planned annual gallium production reduces part of the commercial risk associated with bringing the project into the market. It establishes a reference customer for future production and could increase the attractiveness of the remaining output to companies in semiconductors, telecommunications, aerospace and defence seeking supplies outside concentrated Asian production channels.
The lack of disclosure on the buyer and contractual terms limits the publicly available information on the agreement. The identity of the customer, pricing structure and contractual protections have not been released. It is therefore not known whether the arrangement includes fixed pricing, market-indexed adjustments, minimum purchase obligations or cost-pass-through mechanisms. Such provisions would affect the degree of revenue certainty available to the project during its initial operating period.
Gallium also lacks the deep and transparent market structure found in major traded metals such as aluminium and copper. Transactions are frequently negotiated bilaterally, with premiums influenced by purity, physical form, qualification status, volumes and supply security.
EU strategic status and EIB financing
METLEN’s gallium development has been designated a Strategic Project by the European Commission under the Critical Raw Materials Act. The project has also received support from the European Investment Bank, which approved financing under the REPowerEU framework. The combination of EU strategic-project recognition, EIB financing and a long-term industrial offtake agreement gives the development several layers of institutional and commercial support.
Strategic designation, however, does not by itself ensure that a project reaches construction or production. The development still has to demonstrate dependable feedstock, effective processing technology, environmental compliance, customer acceptance and financial returns capable of supporting the required investment. METLEN’s existing industrial structure addresses several of these requirements. The group already operates a bauxite-to-aluminium production chain, has an established industrial site and employs metallurgical expertise within its operations. Gallium can also be developed as part of a wider investment programme rather than as a completely separate greenfield project.
METLEN balance sheet provides development capacity
The project is being developed within a group that reported €2.10 billion of adjusted net debt. For 2025, METLEN reported €7.11 billion in consolidated revenue, €753 million in EBITDA and €314 million in net profit. Its adjusted net-debt-to-EBITDA ratio stood at 3.1 times.
The EIB financing and customer commitment can reduce the portion of project risk that needs to be carried directly by METLEN’s balance sheet. A bankable offtake arrangement can also support longer-term debt financing and provide greater visibility over project cash flows, although the precise benefit depends on the binding volume and pricing provisions contained in the agreement. METLEN is primarily listed on the London Stock Exchange, with a secondary listing in Athens, and is included in the FTSE 100. The company operates metals and energy businesses across more than 40 countries, providing it with a broader corporate funding base than junior mining companies seeking to finance first production without established operating cash flow.
Greece gains a new critical-material production role
The transaction also links European and US industrial strategies. Both the European Union and the United States are seeking to reduce exposure to concentrated critical-material supply chains, creating scope for production networks in which processing assets in allied economies supply multiple industrial markets. The US agreement allocates 25 per cent of planned annual production to an American technology customer while leaving the majority of the future output available for other buyers. The allocation nevertheless places the project within wider discussions about how publicly supported European critical-material capacity should serve European semiconductor, renewable-energy and defence industries.
For Greece, the development adds gallium to the product base of the Aluminium of Greece complex. The facility has historically centred on bauxite, alumina and primary aluminium, commodities affected by energy costs and global industrial cycles. Gallium represents a lower-volume material connected to technology, defence and advanced power electronics. The project also places emphasis on the value of maintaining metallurgical processing capacity within Europe. Its significance extends beyond Greek bauxite supply to the use of research, process engineering and industrial integration to recover gallium from a broader alumina production stream.
With a qualified US technology customer committed to a substantial share of future output, while the European Commission and European Investment Bank have recognised the project through strategic and financial support, METLEN’s planned gallium operation has secured both commercial and institutional backing ahead of production.
