It has been prepared using the GRI Standards as a reference and complies with the provisions of Law 11/2018 of 28 December, which amends the Commercial Code, the consolidated text of the Capital Companies Act approved by Royal Legislative Decree 1/2010 of 2 July, and Law 22/2015 of 20 July on Auditing of Accounts, in relation to non-financial information and diversity. It is therefore also the Company’s Non-Financial Information Statement for 2025.

The most significant change experienced by the Company in 2025 was Sonaca’s acquisition of 51% of the shares of Aciturri Aeronáutica S.L.U. This purchase process was executed on 1 October and entails a corporate reorganization, as set out below:

These last three entities (Aciturri Aeroengines, S.L.U., Malichaud Atlantique, S.A.S. and GOAM Industrie S.A.R.L.) are included only up to 30 September 2025.

Aciturri Aeronáutica S.L.U. is the parent company, on which the rest depend, with a 100% shareholding, except in the cases referred to in the previous paragraph.

This Sustainability Report (and the previous reports published by the Company) has been prepared based on the results of a materiality analysis, carried out in accordance with the principles of stakeholder inclusiveness, sustainability context, materiality and completeness. It takes as its starting point the previous analyses carried out by the Company regarding its stakeholders and their needs and expectations (Stakeholder dialogue model), as well as the commitments undertaken as a signatory of the United Nations Global Compact.

For the initial reporting year, a group of people forming part of the organization was selected to act as representatives of these stakeholders, due to their ongoing interaction with them. Individually, these people identified the economic, environmental and social impacts of each of the issues proposed in the GRI Standards, and their significance, including those relating to human rights, as well as their influence on stakeholder assessments and decisions.

For the 2020 Report, this analysis was completed by incorporating the concept of risk management. In this way, the impact assessment (consequences by probability) is modified by adding a value derived from the Company’s management of the risk associated with each issue.

Since then, and on an annual basis, a new review of the matrix has been carried out from the perspective of risk management.

The materiality matrix for 2025 is shown in the image.
