Frequently asked questions
Which is the largest employer in Manufacture of basic pharmaceutical products and pharmaceutical preparations in Flanders?
Among companies, Janssen Pharmaceutica, with 5,324.5 full-time equivalents reported (financial year 2025).
Are all 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. 72 out of 300 companies in the sector report employees there.
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.
