Ranking based on each company's own annual accounts (statutory, not consolidated): a subsidiary and its parent appear separately, and the ranking differs from lists based on consolidated group accounts. These are the revenue figures published in the annual accounts. Small companies (micro and abridged accounts) do not have to publish theirs: they do not appear in this ranking.

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.
