“—”: not published. Small companies (micro and abridged accounts) do not have to publish their revenue.

Frequently asked questions

Who is the largest employer in Walloon Brabant?

Among companies, GlaxoSmithKline Biologicals, with 8,371.0 full-time equivalents reported (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.

Are the jobs located in the area?

Not necessarily: headcount is reported by the company for all its sites, and the company is ranked by the address of its registered office.
