Overview

Solid performance for the ElvalHalcor Group in the nine months of 2025. Volumes continued their uptrend, especially in the aluminium segment, which leveraged the new capacity after the conclusion of its investment program. On the other hand, the adverse geopolitical environment, trade tariffs, supply chain disruptions and increased energy costs limited, to some extent, the rate of increase of the group's profitability.

LME metal prices recorded a notable increase during the first quarter of the fiscal year, followed by a de-escalation in late March. For the remainder of the period up to September 30, 2025, prices demonstrated an upward trend. The average price of aluminium stood at EUR 2,300/tn in 9Μ'25, compared to EUR 2,178/tn in 9Μ'24, i.e. higher by 5.6%. The average price of copper was EUR 8,554/tn versus EUR 8,403/tn in the respective prior year period, an increase of 1.8%, while the average price of zinc was EUR 2,483/tn in 9Μ'25 versus EUR 2,473 /tn in 9Μ'24, an increase of 0.4%.

{1}------------------------------------------------

Consolidated revenue for the nine months of 2025 amounted to EUR 2,741.5 million, increased by 5.8% compared to EUR 2,590.5 million in 9M'24, resulting from both increased volumes and higher LME prices. Consolidated adjusted earnings before interest, taxes, depreciation and amortisation, metal result, and other exceptional items (a-EBITDA), which better reflect the Group's operational profitability, increased by 5.1%, reaching EUR 189.2 million in 9Μ'25 versus EUR 180.0 million in 9M'24. Increased sales volumes and improved conversion prices enhanced operational performance. However, higher energy costs, an unfavourable sales mix and the temporary effects on raw materials prices and availability negatively affected the Group's profitability. Accounting metal results stood at a profit of EUR 6.5 million compared to a profit of EUR 3.7 million in the respective prior year period due to higher LME prices, while consolidated earnings before interest, taxes, depreciation and amortisation (EBITDA) stood at EUR 191.0 million compared to EUR 173.2 million in 9M'24.

The significant reduction in the Group's net debt by EUR 48.5 million, from 30.09.2024, along with the lower interest rates, resulted in a 22.5% decrease in the net financial cost to EUR 26.8 million in 9Μ'25, from EUR 34.5 million in 9Μ'24. The debt stood at EUR 686.0 million compared to EUR 788.8 million on 30.09.2024 and, respectively, the net debt at EUR 643.0 million from EUR 691.5 million. The reduction was achieved through strong profitability and limited CAPEX (EUR 57.7 million) despite the significant payment of dividends amounting to EUR 33.8 million (125% higher than 2024). While working capital management remains a high priority for both segments, high LME prices, irregular flow of raw materials, and seasonality affected both segments.

Finally, consolidated profits after tax stood at EUR 98.1 million in 9M'25 versus EUR 75.8 million in 9M'24, and consolidated profit after tax and non-controlling interest amounted to EUR 93.6 million in 9M'25 (or EUR 0.2499 per share), compared to EUR 70.9 million in the respective period of the prior year (or EUR 0.1891 per share).
