To the Shareholders,
This report is issued in our capacity as Statutory Auditor of VINCI. It covers the sustainability information and the information required by Article 8 of Regulation (EU) 2020/852, relating to the year ended 31 December 2025, as presented in chapter E of the Group’s management report, which is included in its Universal Registration Document (hereinafter the “sustainability report”).
Our procedures, which relate to this information, have been performed in an evolving context characterised by uncertainties regarding the interpretation of laws and regulations, and the development of established practices.
Pursuant to Article L.233-28-4 of the French Commercial Code (Code de commerce), VINCI is required to include the above-mentioned information in a separate section of the Group’s management report.
This information provides an understanding of the impact of the Group’s activity on sustainability matters, as well as the way in which these matters influence the development of its business, performance and position. Sustainability matters include environmental, social and corporate governance matters.
Pursuant to Article L.821-54 II of the aforementioned Code, our responsibility is to carry out the procedures necessary to issue a conclusion, expressing limited assurance, on:
This engagement is carried out in compliance with the ethical rules, including those on independence and quality control, prescribed by the French Commercial Code.
It is also governed by the guidelines issued by the Haute Autorité de l’Audit (H2A, the French audit regulator) on limited assurance engagements on the certification of sustainability information and the verification of reporting requirements set out in Article 8 of Regulation (EU) 2020/852.
In the three separate parts of the report that follow, we present, for each of the focus areas of our engagement, the nature of the procedures we carried out, the conclusions we drew from these procedures and, in support of these conclusions, the elements to which we paid particular attention and the procedures we carried out with regard to these elements. We draw your attention to the fact that we do not express a conclusion on any of these elements taken in isolation and that the procedures described should be considered in the overall context of the formation of the conclusions issued in respect of each of the three parts of our engagement.
Finally, where it was deemed necessary to draw your attention to one or more items of sustainability information provided by VINCI in the Group’s management report, we have included an emphasis of matter paragraph hereinafter.
As the purpose of our engagement is to provide limited assurance, the nature (choice of techniques), extent (scope) and timing of the procedures are more curtailed than those required to obtain reasonable assurance.
This engagement does not provide any guarantee regarding the viability or the quality of the management of VINCI. In particular, it does not provide an assessment of the relevance of the choices made by VINCI in terms of action plans, targets, policies, scenario analyses and transition plans, that would go beyond compliance with the ESRS reporting requirements.
Furthermore, as forward-looking information is inherently uncertain, actual future outcomes may differ, sometimes significantly, from the forward-looking information presented in the management report.
Our engagement does, however, allow us to express conclusions regarding the process for determining the sustainability information to be reported, the sustainability information itself, and the information reported pursuant to Article 8 of Regulation (EU) 2020/852, as to the absence of identification or, on the contrary, the identification of errors, omissions or inconsistencies of such importance that they would be likely to influence the decisions that readers of the information subject to this engagement might make.
Sustainability information and the information required under Article 8 of Regulation (EU) 2020/852 may be subject to inherent uncertainty in relation to the state of scientific knowledge and the quality of the external data used. Certain information is sensitive to the methodological choices, assumptions and/or estimates applied in preparing it, which are presented in the management report.
