What MGB does
MGB is a four-generation, family-owned precision bar turning (decolletage) and micromachining subcontractor headquartered in Marnaz, Haute-Savoie, France, operating three production sites in France (75 machines, 4,500 m², €12M turnover in 2025), the USA (Franklin, MA; 16 machines, €2.2M), and China (Shanghai Jiading; 37 machines). The company produces custom turned components ranging from Ø 0.2 mm to Ø 100 mm and up to 400 mm long, in metal alloys and plastics, for production runs of 10 to 500,000 pieces, using a primarily Tornos-based CNC fleet spanning sliding-headstock, fixed-headstock, and Hydromat transfer configurations. Its core technology is qualified co-development and micromachining rather than proprietary software; differentiating tools include 500 ERP-connected GPS-tracking electronic labels for lot traceability, numerical knowledge-capitalization tablets, automated chip sorting with oil recovery, and an in-house FabLab for custom tooling.
The company's revenue model is project-based, quote-driven B2B subcontracting: customers submit part specifications and MGB delivers machined components with optional integrated services (co-development, deburring, heat treatment, partial annealing, surface treatment coordination, assembly, and international logistics). Pricing is bespoke and not publicly disclosed; billing cadence spans multi-year contracts and per-series orders. MGB sells directly to Tier 1 aerospace and defense OEMs (Safran, Thales, MBDA, TE Connectivity, Parker Meggitt, Liebherr, Radiall, Souriau) and to medical and connector manufacturers (Straumann, GE HealthCare, Bausch & Lomb, Amphenol), with end-markets split across aerospace, defense, space, medical, connectors, telecommunications, electric vehicles, and instrumentation. Group turnover reached €17.5 million (~$20.5M USD) in 2025 with 118 employees across the three sites.
MGB's competitive position rests on a deep regulatory and quality certification stack (ISO 9001, ISO 14001, ISO 13485, EN/AS 9100, ITAR, REACH, RoHS, TUV), nearly 70 years of accumulated micromachining know-how, and a multi-continental footprint that delivers supply-chain resilience to Tier 1 buyers. The company reinvests approximately 8–10% of turnover annually into equipment, digitalization, and employee training (3.37% of payroll in France in 2025, above the legal minimum), and reports operational metrics such as >97% on-time delivery and 0 ppm NCR for major aeronautics customers. MGB is privately held under the SA MGB legal entity, with wholly-owned subsidiaries MGB US Inc. and MGB China, no external investors or parent company disclosed, and active engagement in French industry associations including GIFAS, Aerospace Cluster AURA, and UIMM 74.

MGB competitors and assessment
Company assessmentOthers
- Bodycote: Global heat treatment and surface technology services provider (LSE: BOY). Overlaps with MGB only on the heat-treatment/annealing service offering within MGB's integrated subcontracting model — Bodycote is a specialist services provider rather than a parts manufacturer.
- Tornos: Swiss manufacturer of Swiss-type CNC turning machines — MGB's primary equipment supplier across all three sites. While not a parts competitor, Tornos anchors the same micromachining ecosystem and customer base; its installed base and service network shape MGB's competitive landscape.
Broad incumbents
- LISI Aerospace: French tier-1 aerospace fasteners and precision components supplier serving Airbus, Boeing, Safran, and other primes. Comparable customer base and aerospace quality regime, but LISI is a much larger, publicly-listed group with broader product portfolio (fasteners, structural components).
- Aubert & Duval: Large French metallurgical specialist and forged/machined parts supplier owned by Eramet/SAFRAN consortium. Overlaps with MGB on aerospace and defense customers and precision parts production, but operates at much larger scale with proprietary alloys and forging capabilities.
- Precision Castparts Corp. Berkshire Hathaway-owned global manufacturer of complex metal components for aerospace, power, and industrial markets. Comparable in regulated-industry precision manufacturing and aerospace OEM relationships, but operates at incomparably larger scale with proprietary casting/forging processes.
- Howmet Aerospace: Global aerospace engineered products leader (NYSE: HWT) producing precision castings, fasteners, and components for jet engines and airframes. Overlaps with MGB on aerospace precision components and ITAR-driven defense work, but at vastly larger scale and with vertically integrated casting/forging.
Direct peers
- Marle Group: French precision machining specialist focused on orthopedic and dental implants for OEMs like Stryker and Johnson & Johnson. Highly comparable to MGB's medical segment in materials (titanium, medical stainless steel), tolerances, and ISO 13485-driven quality regime.
- Mecachrome: Canadian-headquartered, French-rooted precision machining subcontractor serving aerospace, defense, and motorsport. Directly comparable business model — contract CNC machining of complex, tight-tolerance parts for Tier 1 aerospace customers (Safran, Pratt & Whitney, Rolls-Royce).
- Figeac Aéro: French aerospace subcontractor (€400M+ revenue) manufacturing precision mechanical parts for Airbus, Safran, and other Tier 1 OEMs. Comparable to MGB in customer overlap (Safran, Thales) and aerospace subcontracting model, but at materially larger scale and with broader process capabilities.
- Norman Noble: US-based ultra-precision machining subcontractor for medical implants and aerospace components. Comparable in precision-turning capability, regulated-industry customer base (FDA-cleared medical, aerospace), and reliance on advanced CNC Swiss-type and mill-turn machines.
