Frequently asked questions
Which company in Wallonia has the highest revenue?
Mastercard Europe, with €9.63bn in published revenue (financial year 2025).
Why does this ranking differ from other lists?
It uses each company's annual accounts as filed with the National Bank, not consolidated group accounts. A holding, a subsidiary or a purchasing entity can therefore appear separately. Only companies whose latest accounts are less than 3 years old are ranked.
Why are some companies missing?
Small companies (micro and abridged accounts) do not have to publish their revenue: only the 12,403 that publish it are ranked.
