What ACI Groupe does

ACI Groupe is a French industrial conglomerate founded in 2019 by Philippe Rivière and Patrice Rives, headquartered in Lyon. The group federates more than 35 production sites across five strategic French territories (Loire, Vallée, PACA, Bourgogne-Franche-Comté, and Île-de-France) plus ten international sites, employing between 501 and 1,000 people, and bringing nearly 500 years of combined industrial heritage into a single integrated platform. Its core activity is B2B industrial subcontracting for clients in aerospace, defense (BITD), nuclear, new energy and mobility, railway, and health technologies, with end-customers that include Airbus, Dassault Aviation, Thales, Safran, Hutchinson, Eaton, Circor, Liebherr, Air Liquide, and Framatome.

The group's technology stack spans the full industrial value chain through four business units — Engineering to Product, Manufacturing, Services, and Consumer Brands — covering precision machining (including up to 9-axis turning and 5-axis milling), hot forging, casting, additive manufacturing, surface treatment, welding (TIG, MIG/MAG, brazing), electro-erosion, laser cutting (2D and 3D), tribofinishing, and assembly. Proprietary differentiators include a rare forge-foundry combination spanning over 800 grades of cast iron and steel (grams to 12 tonnes) and high-precision machining of advanced materials such as superalloys, titanium, ceramics, composites, and plastics. Certified under EN 9100, Part 21G, Part 145, ISO 9001, ISO 13485, ISO 14001, and ISO 50001, the group is positioned as a sovereign, Made-in-France supplier for critical infrastructure sectors.

ACI Groupe generates revenue primarily through negotiated, quote-based B2B contracts covering long-term supply of precision parts, sub-assemblies, finished products, and industrial maintenance/MRO/MCO services, supplemented by engineering and design bureaus and equity-linked industrial partnerships such as the planned VoltAero stake in hybrid-electric aviation. Distribution is direct enterprise sales to major CAC 40 primes and global clients in France, with international coverage enabled by the Dviation Group partnership (10+ countries, 5 continents) and the ACI Europe, ACI Pacific, and ACI India subsidiaries. In March 2025 the group raised €80M from US private equity fund Fortuna at a post-money valuation of ~€163M (Fortuna 49%, Rivière 51% with a Golden Share) and has announced a planned IPO on Euronext Growth Paris in autumn 2025.

Revenue model

1. Industrial Subcontracting & Manufacturing: ACI Group generates revenue through the fabrication of precision industrial parts, sub-assemblies, and finished products sold to aerospace, defense, nuclear, energy, rail, and healthcare clients. Revenue is primarily from long-term B2B contracts with major industrial players, with a mix of one-off project orders and ongoing supply relationships. Recent acquisitions include companies generating €3M (Usiduc) and €6M (Fonderies de Sougland) in annual revenue.
2. Services & Maintenance: The group provides industrial maintenance, repair, retrofits, predictive maintenance, and MRO/MCO (Maintenance, Repair, Overhaul, Maintain in Operational Condition) services. This stream includes specialized services for machine tools, lifting equipment, hydraulics, compressors, and aeronautical systems, often delivered through long-term service contracts.
3. Engineering & Design Services: In-house engineering bureaus provide co-design, functional analysis, prototyping, simulation, material selection, and product development services, supporting clients from early concept through commercialization. Revenue is generated as part of integrated project engagements or as standalone consulting.
4. Equity Investment in VoltAero: ACI Group is taking an equity stake in VoltAero as part of a tripartite LOI with SEDC Energy, positioning itself as a strategic industrial partner for hybrid-electric aircraft production in Asia-Pacific. This represents a new revenue/investment stream from industrial partnership.

Direct peers

• Daher: Private French industrial group operating in aerospace manufacturing, nuclear logistics, and industrial services. Directly comparable as a France-based multi-sector industrial player serving the same primes across aerospace, defense, and nuclear.
• Mersen: Public French industrial specialty company producing graphite, carbon, and electrical components for energy, electronics, and transportation (Euronext Paris: MRN). Comparable multi-site French industrial manufacturer with overlap in energy and rail end markets.
• Aubert & Duval: French special alloys and forged parts manufacturer (subsidiary of Eramet) serving aerospace, defense, energy, and nuclear. Directly comparable to ACI's Forges de Monplaisir and metallurgy capabilities, with overlapping customer base in Safran and Airbus.
• Figeac Aéro: Public French aerospace subcontractor (Euronext Paris: FGA) serving Airbus, Boeing, and Safran with precision machined parts, surface treatment, and assembly. Runs a comparable M&A-driven growth model with overlapping customer base to ACI, making it the closest public-market comparable.
• Latecoere: Public French aerospace Tier-1 supplier of aerostructures and interconnect systems (Euronext Paris: LAT). Comparable France-based supplier serving Airbus, Embraer, and other civil aerospace primes, though more vertically integrated than ACI.
• LISI Group: Public French manufacturer of aerospace fasteners, structural components, and automotive parts (Euronext Paris: FII). Multi-site French industrial subcontractor with similar profile to ACI across aerospace and defense primes, though somewhat larger and more mature.

Broad incumbents

• Safran: Public French aerospace giant (Euronext Paris: SAF) manufacturing propulsion, equipment, and defense systems. Comparable as a major French industrial group serving aerospace and defense, though vastly larger and primarily a customer of ACI rather than a true peer.
• Framatome: French nuclear reactor and fuel services company (subsidiary of EDF). Comparable as a major French industrial player in the nuclear value chain, where ACI supplies maintenance equipment and precision components via TCEM, though at vastly larger scale and primarily as ACI's customer.
• SPIE Group: Public French multi-technical services group (Euronext Paris: SPIE) providing installation, maintenance, and energy services to industrial and infrastructure clients. Overlaps with ACI's Services & Maintenance business unit but operates at much larger scale and primarily as a services provider.
• Expleo: Global engineering, technology, and consulting services company with strong French aerospace presence. Comparable in providing engineering and design services to industrial primes, though primarily services-oriented rather than manufacturing, overlapping with ACI's Bureaux d'études & Ingénierie unit.
