About the data
Auditor is the firm currently responsible for the company’s external audit.
Since means the first financial year for which the current audit firm held the engagement — not the year in which shareholders formally approved the appointment.
Audit fee is the latest disclosed fee for audit services, normally FY2025. It excludes tax, consulting and other non-audit services where these are separately disclosed.
All fees are shown in euros and as full values rather than abbreviated figures.
Where a company changed auditor for FY2026, the table shows the new auditor even though the latest published audit fee may still relate to the previous firm.
The data has been checked primarily against company annual reports, auditor reports, governance disclosures and AGM documentation.
