Frequently asked questions
Which company in Activities auxiliary to financial services and insurance activities in Brussels has the highest revenue?
MoneyGram International, with €206.0m of published revenue (financial year 2025).
Why are some companies missing?
Small companies (micro and abridged accounts) do not have to publish their revenue: only the 97 that publish it, out of 837 companies in the sector in the area, are ranked.
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.
