Governance

METLEN demonstrates responsible corporate behavior through its participation in international and national initiatives that promote transparency, and having adopted the 10th principle of the UN Global Compact, actively engages against all forms of corruption, consistently strengthening the culture of integrity at all levels. In addition, the Company seeks to develop strong and long-term relationships of trust and mutual benefit with its suppliers and partners,  while it has as a priority to support its local communities, by entering into partnerships with local suppliers and contractors. At the same time, as part of its strategy for sustainable development, METLEN has started implementing specific initiatives aimed at expanding responsible practices in its supply chain.  According to the 2025 Double Materiality Assessment, the significant impacts associated with the above challenge are:

• Established culture of business ethics / zero tolerance for bribery and corruption
• Emergence of unethical practices in the value chain
• Responsible supply chain management

METLEN recorded measurable results in key areas of responsible business operations, with a focus on ESG supplier evaluation, employee training on ethics and compliance, and ensuring zero tolerance for corruption. In particular,

1. 56 % of key suppliers were evaluated with environmental-social-governance (ESG) criteria.
2. 91 % of key evaluated suppliers were classified as low/negligible risk.
3. 20 online and on-site audits were carried out on assessed key suppliers
4. 2,968 employees were trained in the METLEN Code of Conduct.
5. 3,000 employees completed training in personal data protection (GDPR).
6. 2,462 employees participated in Regulatory Compliance and Whistleblowing training programs, while in 2025 two new training programs on anti-corruption and use of reporting channels were implemented.
7. 57% of all employees participated in anti-corruption and anti-bribery trainings.
8. Zero (0) incidents of corruption or bribery.

Indicative objectives:

1. To enhance the level of maturity through the implementation of training programs to cultivate and integrate a culture of sustainability into its supply chain.
2. The continuation of the implementation of the evaluation of key suppliers with ESG criteria and the gradual extension of the evaluation to new and potential suppliers who take part in tender procedures.
3. The inclusion of an ESG dimension in the tender procedures for the selection of partners/suppliers, taking into account their performance from the ESG evaluation process.
4. The continuation of  on-site inspections at the premises of a sample of evaluated suppliers of the Energy & Metals Sectors and its subsidiaries, which will be selected by the purchasing/procurement departments of the Sectors/subsidiaries, based on the outcome of the ESG assessment.
5. Preparation for the implementation of the renewed supplier assessment approach through the new Third-Party Risk Management (TPRM) System, starting in 2026.
