RESULTS OVERVIEW

Record first half net profit of €59 mn (+20% YoY)

• Turnover reached €2,745 mn, up 0.5% YoY, driven by strong performance in Africa, particularly in E&C and especially in Industrial Engineering, as well as consistent growth in the Environment segment, whilst Latin America reflected a transition period following two consecutive years of significant growth, largely driven by the Tren Maya project in Mexico

• EBITDA amounted to €⁴⁴⁸ mn, with the margin expanding to 16%, reflecting improved profitability, which increased by 13% YoY, driven by robust performance across all business segments

• Net financial results and others reflect the impact of significant capex made in recent years, as well as the interest rate mix of local currency debt in Africa and Latin America, while a more visible improvement is expected from 2026 onwards, driven by the favorable trend in global interest

• Associates reflect the expected performance during the initial stage of the recently operations of the Lobito Corridor in Angola and the new

16% EBITDA margin highlights a sustained commitment to profitability

• In the E&C segment, Africa continued the growth trend observed in 1Q25, standing out as the region with the strongest growth and profitability, driven by both the E&C and Industrial Engineering segments, and consistently delivering as expected following the recent contract awards

• In Latin America, after more than two years of strong double-digit turnover growth, activity adjusted as expected following the completion of the Tren Maya project in Mexico, while profitability remained resilient

• In Europe, performance was impacted by tender and award delays following unexpected elections in Portugal, with some projects only recently unblocked, and public investment is expected to gain momentum from 2026. Turnover declined YoY due to the sale of the Polish operations (€79 mn in 1H24), while the EBITDA margin improved to 8%

• The E&C EBITDA margin of 16% reflects the successful execution of ^a disciplined commercial strategy, rigorous project selection, and ongoing operational optimisation, with profitability and cash generation consistently remaining the main focus

• The Environment segment recorded ^a significant turnover growth (+15% YoY) and a strong EBITDA increase (+20% YoY), contributing to consistent profitability and a sustainable long-term cash flow generation profile

• The OPEX50 efficiency program has positively contributed to strengthening the Group's overall culture of efficiency and its ongoing drive for improved profitability, delivering both immediate and long-term enhancements in business performance ⁹
