What TVI Groupe does

TVI Groupe is a French precision mechanical engineering subcontractor headquartered in Corbas, near Lyon, founded in 2006 by David Dompnier (previously operating under DDPM Holding). The group runs two production entities — TVI Brandolini (Corbas/Chassieu) and TVI Bougault (Saint-Florent-sur-Cher near Bourges) — supported by CKP Engineering (Paris and Cazères), which has been a capital and R&D partner since 2021. Operations span roughly 10,000 m² with 120+ machines and 80+ employees, holding EN 9100 and ISO 9001 certifications required for serving defense and aeronautics programs.

The core offering is custom precision machining delivered to OEMs and Tier-1s across four verticals: defense, aeronautics, railway, and general industry. Capabilities span traditional subtractive machining and metal additive manufacturing (laser powder bed fusion), supplemented by internal reverse engineering, a 1–2 patent/year filing cadence, and a proprietary branded product — the Security Driving System (steering damper) launched in 2022. Pricing is project-based with quote-driven one-time contracts, often converting into multi-year supply relationships once parts are qualified into customer programs.

The group has grown primarily through acquisitions and partnerships: Mécanique Brandolini (2015), the formation-restructuring around Nortier/Bougault/Maret (2017), the CKP Engineering partnership (2021), and the Socoser absorption (2023). Disclosed annual revenue is in the €10–11M band. JEI status (French innovation-program recognition) and the EN 9100 / ISO 9001 certifications form the regulatory backbone for continued penetration of certification-gated defense and aerospace accounts.

Broad incumbents

• Sabena Technics: French aerospace MRO and manufacturing services group. Comparable on the French aerospace manufacturing side and reverse-engineering/discontinued-parts angle, though primarily an MRO platform.
• Aubert & Duval: French manufacturer of high-performance alloys, forged parts, and machined aerospace/defense components. Compares on the metallurgical and aerospace-mechanical component side, though it is far larger and includes upstream materials production.
• Stelia Aerospace (Airbus Atlantic): Airbus-owned aerostructures manufacturer producing composite and metal aerospace parts in France. A direct customer-adjacent comparable in terms of French aerostructures machining, though integrated within an OEM.
• LISI Group: Listed French industrial group with LISI Aerospace division manufacturing fasteners, structural components, and mechanical parts for aerospace/defense. Overlaps with TVI in aeronautics mechanical sub-assemblies, but operates at substantially greater scale and scope.
• Latécoère: Listed French tier-1 aerospace supplier of aerostructures and interconnection systems. Comparable in serving Airbus and other OEMs from French sites, but operates at tier-1 scale rather than sub-tier subcontracting.

Direct peers

• AD Industrie (Acail Group): French precision mechanics subcontractor serving aerospace, defense, and energy with CNC machining, assembly, and additive manufacturing capabilities. Highly comparable mid-cap peer in the French industrial subcontracting ecosystem.
• Groupe Mécanique Générale (GMG): Mid-cap French precision mechanics group offering CNC machining, assembly, and surface treatment for aerospace, defense, and rail. Direct comparable in scope, multi-site French footprint, and customer verticals.
• Figeac Aéro: French aerospace structural parts and precision machining subcontractor serving Airbus, Safran, and Dassault. Direct comparable in aeronautics-focused precision subcontracting, though materially larger (~€300M+ revenue).
• Mecachrome: French precision machining group producing complex aerospace, defense, and energy components. Closely comparable business model with multi-site French footprint and similar customer verticals.

Regional players

• Fonderie & Mécanique Générale (Cyril Martin / similar regional machinists): Regional French precision machining shops competing for similar subcontracting slots in aerospace/defense supply chains. Less identifiable by name; flagged as a class of small regional competitors bidding on the same quote-based projects.
