What Alten does

ALTEN is a French engineering and technology consulting group headquartered in Boulogne-Billancourt, France, operating as a public company (EPA:ATE / OTCMKTS:ABLGF) with a presence in 30+ countries. The firm supplies professional services across 12 industrial verticals — including aerospace, defense, automotive, rail, energy, life sciences, banking, telecoms, retail, and public sector — by deploying consultants directly at client sites and managing projects from concept through deployment. Headcount of 57,000+ (organic perimeter) or 154,000+ including acquisitions includes 51,851 engineers, of which 18,000+ have been trained in AI and 5,000+ are dedicated Data & AI specialists.

Core offerings are organized into engineering services (mechanical and materials engineering, embedded software compliant with DO178/EN50128/EN62304/ISO26262, systems engineering, manufacturing engineering, quality assurance) and IT services (application software, cloud and infrastructure, cybersecurity, data management, AI, PMO). Technology differentiation centers on 60+ preconfigured AI accelerators, 18 AI Centers of Excellence, and an AI-driven BI platform built on Snowflake and Amazon Bedrock. Service delivery is amplified by a subsidiary ecosystem including SDG Group (data/AI consulting, acquired 2020), Lincoln (data consulting), MIGSO-PCUBED (PMO, subsidiary since 2003), Solwit (Poland, 2023), plus sector specialists (Worldgrid, Anotech Energy, Energy4U, Aixial, Caduceum, Nexeo, Atexis).

The business model is professional services — time-and-materials and multi-year contracts priced on consultant day rates by seniority and geography, with nearshore/offshore centers in Romania, Spain, Poland, Morocco, and India providing cost optimization. Revenue reached €4.10B in FY2025 (up from €3.78B in 2022), with Q1 2026 at €1.7B. Customers include Airbus, CNES, major European aerospace and automotive OEMs, rail operators, global pharmaceutical companies, and Mexican solar developers. Long-running M&A (20+ acquisitions since 2004) has been the primary lever for both geographic expansion (Methods 2022 in the UK/Nordics, Solwit 2023 in Poland) and capability extension (SDG Group for AI/data).
