In 2025, a total of 13 team members underwent specialized training in sustainable procurement through the Ecovadis Academy platform. This training enables them to incorporate increasingly rigorous and effective criteria into purchasing processes, thereby contributing to continuous improvement in the sustainable management of the supply chain.

Aciturri actively encourages its suppliers to comply with fundamental standards in the areas of human rights, working conditions, occupational health and safety, environmental protection and ethical conduct. This commitment is based on the Company’s Code of Conduct, the Procurement and Subcontracting Policy and the Ethical and Socially Responsible Management Policy, as well as on support for the Ten Principles of the United Nations Global Compact, the Universal Declaration of Human Rights and the Social Policy of the International Labour Organization. These principles cover the eradication of forced labour and child labour, the guarantee of decent working conditions, respect for freedom of association and collective bargaining, equal opportunities without discrimination on grounds of sex, age or other circumstances, the payment of adequate wages and the limitation of excessive working hours.

Aciturri does not establish commercial relationships with companies that do not comply with the ethical and social principles set out in the aforementioned documents. It is essential that all collaborating companies strictly respect current labour and environmental legislation, as well as maintain conduct and attitudes aligned with respect for human rights and the environment. Once the contractual relationship has begun, compliance with these commitments is required through the inclusion of specific clauses in contracts, thereby guaranteeing transparency and responsibility at every stage of the collaboration.

In the decision-making process relating to the supply chain, Aciturri considers the impact that logistics may have on the carbon footprint, the reduction of associated consumption and the generation of waste to be key.

To reflect Aciturri’s commitment to respect for human rights within the organization, the Company has a Human Rights Policy (see “Compliance” section). In addition, through the Supplier Code of Conduct, it asks its suppliers and subcontractors to uphold the same commitment as the Company has in this matter, accessible on the Aciturri website (link).

Monitoring of supplier performance and processes is continuous, through the performance of an assessment applied under a standardized methodology and with the purpose of identifying opportunities for improvement and internally evaluating Aciturri’s capacity to meet its customers’ expectations and satisfy their needs.

The main tool used in this process is the Aciturri Supplier Assessment (ASA), which evaluates four aspects: processes, organization, tools and indicators.

The assessment questionnaire includes, in block “8.1 Health and safety management system”, three sections: ethics and compliance, digitalization, and safety, health and environment.

Throughout 2025, a total of 17 quality audits were carried out on the supply chain, with an average score of 97 points out of 100.

In parallel, the ASA industrial maturity assessment was carried out on 5 strategic suppliers throughout 2025, with an average score of B (the possible ratings are A+, A, B, C or D).

As a result of this assessment, a specific report is generated including the improvement points detected, the associated action plan, and an overall rating (A+, A, B, C or D). The person responsible for the assessment monitors the improvement plan to strengthen and develop the supplier’s key processes.

In addition, throughout 2025, an Engineering Audit plan was deployed, in which a total of 5 suppliers were assessed. Four of them were assessed jointly with the ASA, and one specifically; the average score was 64 out of 100.
