As we have consistently demonstrated throughout our history, we remain committed to delivering on our strategic objectives, creating sustainable long-term value for our shareholders and all our stakeholders, with a clear focus on consistently achieving high standards of performance."

1.   KEY FINANCIAL FIGURES

Revenue reached €3,987 million in H1 2026, up 11% from €3,608 million in the corresponding period of 2025. The increase was mainly attributable to the Energy Sector, where revenue rose by €218 million to €3,134 million. Higher natural gas trading activity was the main driver of this increase, with gas trading revenue rising to €853 million from €618 million in the prior-year period. Retail electricity and gas sales also increased, reflecting growth in customer volumes.

EBITDA increased by 23% to a record first-half level of €550 million, compared with €445 million in H1 2025, reflecting strong contributions from all business platforms. The Fully Integrated Utility was a key driver of performance, benefiting from the strength of its integrated business model, operational synergies and the efficiency of METLEN's generation fleet. The Metals Sector also delivered a strong performance, with EBITDA rising to €149 million, supported by Management's timely commercial and operational actions, which enhanced cost efficiency, improved realised pricing and strengthened margins. Infrastructure & Concessions more than doubled its EBITDA to €82 million, benefiting from strong revenue growth, disciplined project execution, an expanding project portfolio and a backlog approaching €2 billion.

Net profit after minorities came in at €313 million, representing a 23% increase compared to €254 million in the corresponding period of 2025.

The strategic initiatives presented at the 2025 Capital Markets Day continue to progress on schedule and are expected to drive METLEN's EBITDA towards the €2bn level. The alumina expansion and first gallium production remain on track for H2 2027, while the Defence business is expected to deliver a significant step-up in profitability from 2027, reaching its medium-term earnings target by 2028-2029. With the majority of investments expected to achieve payback in less than two years, the programme is set to generate attractive returns and substantial long-term shareholder value.

Disciplined execution enabled part of the 2026 investment programme to be brought forward into 2025, reducing expected 2026 CAPEX below the April 2025 CMD assumption. Combined with continued strong cash generation, this is expected to provide further support to the Company's balance sheet, building on the c.€0.7 billion reduction in adjusted net debt achieved in H1 2026 through the successful execution of METLEN's Asset Rotation model and the strong cash conversion of its integrated business model.

2.   SECTORAL OPERATIONAL UPDATES

2.1. Energy Sector

During H1 2026, METLEN successfully completed the strategic reorganisation of its Energy business, simplifying its structure from five divisions into two integrated platforms - M Renewables, Storage & Energy Transition (M RESET) and Fully Integrated Utility - with the aim of enhancing execution, commercial coordination and capital allocation.

Energy Sector reported revenue of €3,134 million, representing 79% of the Group's total revenue. Earnings before interest, taxes, depreciation and amortisation (EBITDA) stood at €331 million, reflecting a 15% increase from €288 million in H1 2025.

2.1.1.  Renewables, Storage & Energy Transition Platform (M RESET)

* Includes projects of all technologies (photovoltaic, energy storage, wind)

**Project ready to be built (RTB) or that will reach RTB stage within the next ~ 6 months

The company's total global portfolio, excluding PPC-related transactions, surpassed 12 GW. As of the end of the first half of 2026, METLEN's mature and operational portfolio reached 5.1 GW, while another 7.2 GW at earlier stage of development.

Global electricity generation from RES amounted to 0.9 TWh in H1 2026, marking a 3% increase year-on-year. Of this total, 0.4 TWh were generated from Greek RES assets, with the remaining 0.5 TWh produced by international operations, underscoring METLEN's accelerating growth trajectory and its expanding footprint in the global green energy landscape.

In line with its Asset Rotation model, METLEN completed the sale of a 283 MW solar portfolio in the UK. Based on the maturity profile of its global portfolio and its proven track record of delivering 1.0-1.5GW of asset rotations annually, the timing of Asset Rotation transactions supports expectations for a stronger contribution in H2 2026. Backed by a geographically diversified operating model and the successful execution of its Asset Rotation strategy, METLEN continues to operate a largely self-funded growth model, supporting disciplined leverage, a strong credit profile and long-term value creation.

METLEN continued to advance its BESS pipeline during H1 2026, with projects progressing across Australia, Chile, Greece, Italy and Romania. The expanding portfolio is expected to further enhance the Group's presence in the energy storage sector and support its long-term growth across key international markets.

During the period, the Company successfully energised more than 400MW of BESS projects across Greece and Italy, including a 48MW/96MWh project in Chalkidiki, METLEN's first operational BESS asset in Greece, and a 25MW/75MWh project in Italy. In addition, METLEN energised the 330MW/790MWh Thessaly BESS project. As the largest standalone battery energy storage facility in Greece and one of the largest in Europe, the Thessaly project represents a significant milestone for the Greek energy market.

Building on this momentum, METLEN entered into an agreement for the construction and operation of a hybrid project of 251MW/375MWh and also entered into a joint venture agreement with one of its strategic partner for the development, construction and operation & maintenance of existing BESS projects, targeting a total capacity of up to 1.5GW/3.0GWh, contributing materially to the Group's half-year performance.

Furthermore, third-party EPC activities remained a key contributor for METLEN during the period, further strengthening the Group's position as a leading contractor in the global RES sector. During H1 2026, new agreements were secured for photovoltaic (PV) projects with a total capacity of 0.5 GW and BESS projects of 0.4 GWh across Greece, Italy, and the United Kingdom. In addition, a further pipeline of PV and BESS projects totalling 0.4 GW / 1.2 GWh is currently at an advanced stage of contractual negotiations, highlighting the continued momentum of METLEN's third-party development and execution activities. As of the close of H1 2026, M RESET's contracted backlog stood at c.€1.3bn, with a further €0.2bn under advanced negotiation.

The former MPP business has now been fully integrated into M RESET and repositioned to pursue selective international opportunities aligned with the broader energy transition. During H1 2026, METLEN made significant progress in executing the legacy contracts that weighed on 2025 performance and currently since the beginning of the year achieved: ''First Fire'' milestone at the Grudziądz CCGT in Poland, reached the "First Fire on Oil" milestone at the Protos in the UK, and now approaching the "Readiness to Receive Waste" milestone at Protos in the UK and handed over the first of three 299MW OCGT units under the Drax contract. As the legacy projects are approaching completion, METLEN recognised additional completion costs in its half-year results as they progressed through the final stages of delivery. In parallel, METLEN successfully delivered the Synchronous Condenser project (Pembroke) in UK, its second data center in Greece and energised the Elbasan 3 and Fier 400kV substations in Albania, further demonstrating its execution capabilities across critical energy and digital infrastructure.

2.1.2.  Fully Integrated Utility

Greek Market Data

              ¹Renewable Energy Sources

In H1 2026, Greece further strengthened its position as a net electricity exporter, with net exports reaching 5.2 TWh versus 0.8 TWh in H1 2025, reflecting a significant increase in cross-border electricity flows. Total domestic electricity generation rose by 18% year-on-year (YoY) to 30.1 TWh, primarily driven by continued renewable energy capacity expansion, which now accounts for almost 50% of domestic electricity production. METLEN's Greek renewable generation recorded a 21% increase YoY. Hydroelectric generation more than doubled, supported by improved hydrological conditions and higher rainfall, contributing to higher domestic electricity supply during the period.

The significant increase in net electricity exports during the period highlights the country's evolving role as a net exporter in the region, creating opportunities for integrated energy platforms with technologically diversified portfolio, supply and trading capabilities. The continued expansion of renewable generation is expected to accelerate the transformation of the Greek power market, increasing the importance of flexible thermal generation, storage assets and sophisticated energy management capabilities to balance the system and capture value across the electricity value chain.

Leveraging the most efficient natural gas fleet and a rapidly expanding RES portfolio, METLEN continues to benefit from Greece's growing role as a regional electricity exporter, while strengthening its position as the country's leading independent integrated utility. Despite broadly stable generation volumes year-on-year, the Company continued to expand profitability by leveraging its integrated business model, capturing operational synergies and benefiting from the efficiency of its best-in-class generation fleet in Greece.

Protergia further strengthened its position in the Greek electricity market, increasing its market share to 21.5% by the end of June 2026 (IPTO data), up from 19.6% a year earlier. This translated into electricity supply volumes of c.5.1 TWh during H1 2026, compared with c.4.7 TWh in H1 2025.

The retail natural gas business also delivered another period of strong growth. Protergia's market share exceeded 29% during the first six months of 2026, up from 26% in the corresponding period of 2025, with gas supply reaching approximately 1.7 TWh. At the same time, its customer base continued to expand, reaching 71,000 meters, compared with c.61,000 a year earlier.

As Greece's largest independent electricity supplier, Protergia continued to expand its market share, further strengthening the integration of METLEN's Fully Integrated Utility model. This enhances the Group's ability to optimise value across the entire electricity value chain-from generation and trading to retail supply-while providing a strategically important route-to-market for its growing generation portfolio.

METLEN remains on track to deliver its medium-term integrated utility strategy, under which retail supply is expected to gradually reach around 30% of Greece's total electricity consumption.

The Company's strategy is to progressively align electricity sales with its generation output, creating a balanced generation-and-supply portfolio that provides a natural hedge against wholesale market volatility. This enhances earnings visibility, improves margin stability and enables METLEN to capture greater value across the entire electricity value chain.

Total natural gas procurement reached a record level of c.32 TWh in H1 2026, representing an increase of more than 26% compared with H1 2025. During the same period, METLEN sold c.22.5 TWh of natural gas to third parties, up more than 45% year-on-year, further reinforcing the Group's position as a leading natural gas supplier and trader in Southeast Europe.

The natural gas supply and trading business is an integral part of METLEN's business model, enhancing operational efficiency across the value chain. The scale and diversification of the Group's procurement portfolio, supported by multiple sourcing arrangements and pricing mechanisms - including the recently announced strategic LNG supply partnership with Shell - enable METLEN to optimise gas procurement, supplying its own operations while maximising value through third-party sales. This integrated approach supports margin resilience, enhances earnings visibility and underpins the long-term growth of the Group's utility platform.

2.2. Metals Sector

Following METLEN's strategic reorganisation, the Metals Sector has been structured around three integrated pillars-the Vertical Aluminium Value Chain, Critical and Rare Metals (M-CRM), and M Technologies (Advanced Metal Technologies) - strengthening the Group's positioning as a leading European strategic materials and industrial technology platform. Significant progress has already been achieved across all three pillars, with key initiatives advancing according to plan and supporting METLEN's long-term growth strategy.

Metals Sector reported EBITDA of €149 million, representing an increase of c.15% year-on-year, reflecting higher realised prices and enhanced operational cost efficiency, resulting in stronger margins. The Sector continues to benefit from elevated aluminium prices and premia, supporting both aluminium and alumina sales (the latter linked to the LME aluminium price index). Market conditions remain favorable, underpinned by tight physical supply and disruptions in the Gulf, while METLEN's fully vertically integrated business model and strategic location at the heart of Europe enhance its resilience to industry disruptions.

Aluminium Value Chain (Bauxite, Alumina and Aluminium production)

The LME 3-month aluminium price continued its upward trend from late 2025, averaging c.$3,362/t in H1 2026, representing a sharp increase of c.32% year-on-year. In addition to Europe's structural dependence on aluminium imports, the increase was driven by supply disruptions linked to the Iranian conflict. The disruptions in the Middle East had an immediate impact on market sentiment and physical metal availability, pushing an already deficit market further into deficit, enhancing aluminium market's tightness.

METLEN has fully hedged its aluminium and majority of calcined alumina production for 2026, 2027 and 2028 at progressively higher prices, while also hedging its key cost component - energy - thereby securing steadily improved margins going forward.

In Europe, aluminium billet and slab premia have increased sharply since the beginning of the year, now exceeding the $1,200/t level, driven by sustained demand for European aluminium value-added products (VAPs). These elevated premia are expected to be fully reflected in aluminium profitability in the second half of the year, with an initial contribution already evident in Q2 2026.

In H1 2026, the average alumina price index (API) declined significantly to $307.3/t, compared with $435.5/t in the corresponding period of 2025. Despite the API weakness, METLEN continues to deliver robust alumina profitability, supported by timely management actions, including the partial indexation of calcined alumina sales, across both new and existing contracts, to the LME aluminium price rather than the alumina price index.

Critical and Rare Metals

During H1 2026, METLEN continued to advance its bauxite, alumina and gallium investment programme, representing a total investment of c.€300m, including the development of Europe's first industrial-scale gallium production facility. The project has secured significant institutional and government support, including c.€118m in grants and tax incentives, alongside €90m of EIB.

METLEN has recently announced a flagship offtake agreement covering c.25% of its expected annual gallium production (currently at 50tpa), providing early commercial validation of the project and significantly de-risking the initiative well ahead of first production (H2 2027). In addition, the Company continues to observe strong offtake interest from customers across the globe, with further agreements expected to be concluded in the near term. This interest remains strong despite the current elevated gallium price environment, with prices today exceeding the $3,000/kg level compared with the $1,000/kg assumption underpinning METLEN's CMD profitability case. This highlights the increasing strategic importance of security of supply for critical materials, such as gallium, with customers prioritising supply certainty over short-term price considerations.

Similarly, the Circular Metals initiative is progressing well, with positive initial results from the demonstration plant consistent with the laboratory-scale tests. The Company is currently advancing the optimisation of the expansion plan, the outcome of which will inform the scope, configuration and timing of the final investment decision for the proposed 0.5Mtpa expansion facility.

M Technologies

During the first half of the year, M Technologies (Advanced Metal Technologies) continued to execute its growth strategy, strengthening its industrial footprint and expanding its presence in the defence sector. Key milestones included the inauguration of two new production facilities (Plants 3 and 4) at the Volos Defence Hub, ahead of schedule, further enhancing the Company's manufacturing capabilities, and continued improvements in operational efficiency and workforce development, driving higher production and delivery rates during the period. In addition, METLEN expanded its Volos Defence Hub, through the acquisition of an additional facility (former NK Trailers), bringing the total number of operational units to six, ahead of the targets communicated at the CMD, and positioning the business to capture growing demand for defence systems.

At the same time, M Technologies expanded its activities in land and naval defence systems, with a particular focus on air defence programmes, while deepening collaborations with leading international defence OEMs and further strengthening its pipeline of strategic opportunities, supported by the sustained increase in European defence spending.

2.3. Infrastructure and Concessions Sector

The Infrastructure and Concessions Sectors continue to perform in line with management's expectations for profitability and growth. H1 2026 delivered particularly strong financial results, which were significantly supported by the intensive pace of execution of RRF-funded projects that are scheduled for delivery during the summer of 2026. EBITDA more than doubled compared to H1 2025, supported by stronger margins, reflecting the project mix of H1 2026. METKA ATE continues to maintain a leading position in the sector, enjoying market recognition, thereby securing a strong project portfolio (the total backlog of infrastructure projects under execution, including projects at an advanced stage prior to contract award, exceeds €2 billion) and actively capitalising on new opportunities. Leveraging their expertise and strategic position, METKA ATE and M Concessions are strengthening their position in the fields of public and private projects and PPP projects, contributing substantially to the creation of long-term value.

The key developments during H1 2026 include the following:

In January 2026, METKA ATE signed the contract with the Jewish Community of Thessaloniki, marking the commencement of construction works for the Holocaust Museum of Greece at the site of the former Thessaloniki Railway Station.

In February 2026, the METKA ATE - MESOGEIOS AQUA S.A. Joint Venture signed the contract for the "Construction of the Kavala Non-Hazardous Solid Waste Treatment Facility & Supply of Mobile Operational Equipment for the Kavala Waste Treatment Facility". Project budget: €81.7 million, with an option right.

In February 2026, M Concessions agreed to acquire a 24% participation in the concession company DIKTAION PARACHORISEIS Single-Member S.A. for the project "Northern Road Axis of Crete (VOAK) - Chania-Heraklion Section" and METKA ATE initiated procedures to participate with a 30% stake in the new Construction Joint Venture (together with TERNA and AKTOR ATE), which will replace the Contractor as the Main Design-Build Subcontractor of the project "Northern Road Axis of Crete - Chania-Heraklion Section", with a total construction value exceeding €1.5 billion.

In March 2026, METKA ATE signed a contract with NORTH STAR ENTERTAINMENT AND TOURISM S.A. for the implementation of the development, hospitality and entertainment project - VORIA - in Maroussi, which includes the construction of a 300-bed five-star hotel, casino, event and dining facilities, as well as extensive public areas and infrastructure. Budget value exceeding €150 million.

In April 2026, M Concessions was awarded preferred bidder status for the University of Western Macedonia Student Residences PPP project. NPV: €85 million.

In April 2026, ELEMKA S.A. signed a contract for the implementation of the project "Maritime Heritage Park, Odysseus - The Greeks and the Sea", in the Floisvos area, Municipality of Palaio Faliro.

In May 2026, METKA ATE signed a contract with FILMA ESTATE S.A. for the implementation of Phase A of the development project for a building complex within the site of the former FIX Brewery in Thessaloniki.

During the same month, the "METKA ATE - DOMIKI KRITIS S.A." Joint Venture was awarded preferred bidder status for the Skaramagas Triple Junction project. The contract was signed in July 2026. Project budget: €49 million (with an option right, without VAT).

In June 2026, the TERNA - METKA ATE - Iliochora - ELEMKA consortium was awarded the project "Creation of an Urban Metropolitan Park at Faliro Bay Area". Project budget: €255 million.

In June 2026, ELEMKA S.A. signed a contract with ELATOS DEVELOPMENT P.C. for the implementation of a project involving the upgrade and expansion of an existing hotel unit.

The execution of works for the projects "PPP Upgrade of the Thessaloniki Inner Ring Road (FlyOver)" by the AVAX - METKA ATE Joint Venture and "Restoration of the Double Athens-Thessaloniki Railway Line, Domokos-Krannonas Section, following Storms 'Daniel' and 'Elias'" by METKA ATE, as well as numerous other public and private projects, is progressing smoothly. Among these, the project "PPP 17 Bioclimatic Schools of Central Macedonia" is progressing partly ahead of schedule, with two school units moving towards delivery at the beginning of the school year.

For H2 2026, METKA ATE is expected to continue its operations seamlessly through the continued execution of projects included in the Company's backlog, the commencement of works under contracts signed during H1 2026, as well as the signing of contracts for projects in which it has already been selected as contractor.

In the medium term, the prospects of the construction sector in Greece remain particularly positive, both for public and private works and for Concession and Public-Private Partnership (PPP) projects, in which the Infrastructure Sector (METKA ATE and M Concessions) has already begun to play a significant role.

At present, several major infrastructure projects are at various stages of tendering, either as pure public works (railway projects, Metro Line 2 extension) or as PPP projects (building projects such as the relocation of Korydallos Prison, environmental projects, etc.), in which METKA ATE, both independently and as construction contractor of its affiliated company M Concessions, aims to play a significant role, contributing meaningfully to the results of its parent company.

In addition, significant private building projects are currently in the tendering phase, a sector in which METKA has established itself as a reliable partner.

Prospects

METLEN's remains on track to achieve both its short-term (2026) as well as its medium-term objectives as outlined during the Company's AGM. Further analysis regarding the Company's financial results, prospects, business developments and strategy will be discussed by METLEN's Management in the scheduled conference call on Thursday 6/8/2026, 11:00 am (UK TIME).
