ENTREPRISES Jean NONET et FILS, with €65.9m 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 13 that publish it, out of 77 companies in the sector in the area, are ranked.
Why does this ranking differ from other lists?
