Building on its traditional renewables business, the platform gained momentum across development, EPC and integrated energy services, while gradually growing its activity in Grid and Data Centers.

M ETP’s legacy project business achieved important milestones in the delivery of complex energy infrastructure projects internationally.

• First Fire on Waste at the PROTOS ERF facility being developed for Encyclis in Cheshire, marking the transition to the final stages of hot commissioning.
• First Fire at the 560 MW combined-cycle gas turbine power plant being developed for CCGT Grudziądz, a subsidiary of Energa and part of the ORLEN Group.

2. Metals Sector

METLEN continued to strengthen the competitiveness and strategic importance of its Metals Sector through investments in the integrated aluminium value chain and the development of European gallium production.

M Aluminium Value Chain

• Strategic investment of nearly €25 million in EP.AL.ME., aimed at expanding recycled aluminium processing capabilities through modern, highly automated sorting, processing and melting equipment. Once fully developed, the Aluminium Value Chain is expected to deliver cost competitiveness, reduce the environmental footprint and increase combined aluminium production to more than 250,000 tonnes per annum.
• The landmark project Leader, involving an expansion of Bauxite activity, a 50% increase of our Alumina to 1.3Mio tonnes, and the 50MT p.a. gallium plant, is proceeding exactly as scheduled.

M Critical and Rare Metals

• M CRM has secured two landmark long-term commercial agreements for the future supply of gallium from its production facility in Greece, currently under construction, covering approximately 25% and up to 16% of its total annual production, respectively. Both agreements highlight strong international demand for secure, diversified sources of critical raw materials and position METLEN at the forefront of efforts to establish a competitive European gallium value chain.
• Commissioning is progressing according to schedule at the Critical Metals demonstration plant in Thessaloniki, which combines proprietary technology with unique industrial capabilities and secured own and third-party feedstock. The first shipments of high-purity metal oxides are expected to roll through the gate by year-end 2026, marking an important milestone towards supporting Europe’s technological and industrial resilience and unlocking significant long-term commercial opportunities for the Company.

M Technologies

M Technologies continued to expand METLEN’s presence in the defence and advanced metal technologies, combining programme participation with strategic industrial partnerships and measurable operational gains.

• In the Republic of Cyprus, M Technologies signed and exclusive Partnership Agreement with HOUTRIS to develop new industrial capabilities in defence systems. The agreement provides for the establishment of a joint company, to support technology transfer, skills development and the strengthening of Cyprus’ defence industrial base. Under the European SAFE programme, the new entity will proceed with the production of military vehicles, while the partners will explore further opportunities in production, integration, support and maintenance of defence systems.
• At the Volos Hub, the operational excellence programme launched this year delivers tangible results, with lead times reduced by 50% and production almost doubling compared to the first 9 months of 2025. The approach is being standardised into a replicable operating model, supporting execution of M Technologies’ growing backlog as new plants come on stream.

3. Infrastructure and Concessions Sector

METKA Group is advancing the consolidation and development of its infrastructure-related activities under an integrated infrastructure platform, while advancing major construction projects and strengthening its execution capabilities. The period was marked by new contract awards and progress across key infrastructure projects.

The Infrastructure & Concessions segment and the new METKA Group are not directly comparable due to differences in their respective scope and perimeter.

• Strategic reorganisation: Following the announcement of the spin-off of PPP and concession-related activities, METKA Group continued to implement the consolidation of its construction, concessions, PPP investments and facility management activities under an integrated infra platform.
• The Company is reviewing strategic options, including a potential listing of METKA Group in Euronext Athens, with a view to supporting its growth, capital requirements and financial autonomy. Any potential transaction remains subject to relevant market, corporate and regulatory considerations.

• Skaramagas and Western Aigaleo Ring Road: METKA, in joint venture with DOMIKI KRITIS, signed a €60.5 million contract with the Ministry of Infrastructure and Transport for the construction of three interchanges in the wider Skaramagas area and completion of the relevant section of the Western Aigaleo Ring Road. The contractual construction period is 36 months.

• Flyover project, Thessaloniki: Construction progress reached approximately 65%, with completion targeted for May 2027.
• School infrastructure in Central Macedonia: Four of the 17 school units included in the programme were delivered in 3Q 2026 ahead of the contractual schedule, with a further six expected to be delivered during 4Q 2026.
• AENAON Metropolitan Park, Faliro: The contract for the project was signed on 2 September 2026 by the Region of Attica and the TERNA–METKA–ILIOCHORA–ELEMKA consortium. Site establishment is expected in November 2026, with construction scheduled to commence in January 2027 and completion anticipated in the second half of 2029.
• Acquisition of a 49% stake in KOSMO KATASKEVASTIKI S.A.: METKA announced an agreement to acquire a 49% stake in the Greek earthworks specialist, strengthening its access to critical excavation, earthmoving and site preparation capacity. The investment is intended to enhance execution readiness, resource availability and the coordination of complex infrastructure projects.

3. Post-period events

• On 2 November 2026, METLEN signed a binding five-year agreement with Shell Global LNG Limited for the supply of six LNG cargoes annually (approximately 0.6 bcma), commencing in 2027. The cargoes will be sourced primarily from Shell’s US LNG portfolio for supply to Greece and access to other European markets through the Vertical Gas Corridor. The agreement builds on the February 2026 MoU and strengthens METLEN’s long-term supply portfolio, sourcing diversification and commercial flexibility.

• On 12 October 2026, METLEN signed a collaboration agreement with Thales Alenia Space and Thales Hellas to jointly prepare for potential opportunities under Greece’s future defence telecommunications space programme. The agreement establishes a framework for assessing the partners’ respective capabilities and potential contribution to a future end-to-end defence telecommunications space system. The agreement also envisages the potential use of METLEN’s future gallium production capabilities in relevant supply chains for satellites built by Thales Alenia Space.
