Alten Belgium
ALTEN Belgium is a Belgian besloten vennootschap (BV) / société à responsabilité limitée (SRL), registered with the Crossroads Bank for Enterprises (KBO/BCE) under enterprise number BE 0471.960.230. The company was incorporated on 24 May 2000, and its registry status is listed as active, in normal legal standing. Its registered address is Chaussée de Charleroi 112 (Charleroise Steenweg 112), 1060 Saint-Gilles, in the Brussels-Capital Region.
ALTEN Belgium’s principal business activities, per its KBO/BCE registration, fall under NACE codes 62.200 (computer consultancy and computer-facility-management activities) and 71.121 (engineering and related technical consultancy activities). The company provides information-technology consulting and engineering and technical advisory services to business clients.
Based on the company’s most recently filed annual accounts, ALTEN Belgium reported turnover of approximately EUR 79.7 million for the 2025 financial year and a workforce in the range of 500-999 employees on a full-time-equivalent basis, according to commercial registry data drawing on its filed accounts. A separate commercial data source cites a turnover figure closer to EUR 85.3 million for a recent prior period; this discrepancy reflects differences between data providers rather than a confirmed year-on-year change and has not been independently reconciled against the company’s own filed accounts.
The company operates two branch establishments in Belgium and is registered for VAT and with the Belgian social security administration (RSZ/ONSS) as an employer.

Shareholders
Shareholders of ALTEN Belgium
No individual or corporate shareholders with specific shareholding percentages are disclosed in the publicly accessible Belgian registry sources reviewed for this profile (KBO/BCE Public Search, companyweb.be, pappers.be). Belgium’s free company registry (KBO/BCE) does not publish shareholder registers or ownership percentages for private companies; that information is generally only available through Belgium’s UBO Register (Registre UBO / UBO-register) to parties with legitimate access, or via paid commercial data services not consulted in this research.
ALTEN Belgium’s registered name and official website (alten.be) are consistent with the ALTEN group’s branding, and Zavia’s internal corporate-linkage data places the company within the same group record as ALTEN’s French top-level group entity (registration number FR 34860741700048). This linkage indicates group affiliation but does not itself constitute a disclosed shareholding percentage.
Ultimate beneficial ownership
No verified ultimate beneficial owner is disclosed in the sources reviewed. Belgium’s UBO Register was not accessible as part of this research, so no UBO name, ownership path or effective percentage can be reported.
Data availability
Shareholder and UBO information for this company is classified as Not public / Restricted: the KBO/BCE public search does not display shareholding percentages, and no verified shareholder or UBO information was located in the free registry sources checked as of 23 September 2026.

Group Structure
Group structure of ALTEN Belgium
ALTEN Belgium (BE 0471.960.230) is part of a verified corporate group associated with ALTEN, a French engineering and technology consulting group whose top-level group entity carries French registration number FR 34860741700048 and whose listed parent, ALTEN SA, trades on Euronext Paris (ticker ATE, ISIN FR0000071946), headquartered in Boulogne-Billancourt, France. Zavia’s internal corporate-linkage data places ALTEN Belgium as a member entity of this group structure. The precise immediate parent of ALTEN Belgium within the group (for example, whether it is held directly by ALTEN SA or through an intermediate holding entity such as ALTEN Europe) and the applicable ownership percentage were not confirmed in the free sources reviewed, so the relationship is best described as a verified group affiliation rather than a fully documented ownership chain. No direct or indirect subsidiaries of ALTEN Belgium itself were verified. The same group record lists numerous other entities operating across France, the UK, Germany, the Netherlands, Spain, Portugal and other countries, but these are sister entities within the wider group rather than confirmed links in a direct ownership chain to ALTEN Belgium.
