Riber

What Riber does

Riber S.A. is a French public company (Euronext Growth Paris: ALRIB) founded in 1964 and headquartered in Bezons, France, that is the world's leading supplier of Molecular Beam Epitaxy (MBE) equipment and related services for the compound semiconductor industry. The company designs and manufactures a portfolio of MBE systems spanning research to mass production — including the Compact 21 (the world's best-selling research MBE), MBE 412, MBE 49, MBE 6000, MBE 32 (including HgCdTe/MCT variants), and the recently launched MBE 8000 mass-production platform — complemented by the proprietary Crystal XE process-control software and EZ-CURVE / EZ-REF in-situ monitoring tools. Riber is extending its technology frontier into silicon photonics and quantum hardware through the ROSIE platform (functional oxide epitaxy on 300mm silicon wafers) and the Supra Hybrid Platform for cryogenic qubit growth.

Riber generates revenue primarily through one-time capital sales of MBE systems (€29.0M from 13 systems in 2023) supplemented by recurring services, spare parts, upgrades, and OEM components from its installed base (€10.3M in 2023), reaching €40.3M in FY2025 revenue with €5.2M net income (+27% YoY). The company sells directly to major universities, material-science institutes, compound-semiconductor foundries, and epiwafer suppliers worldwide via wholly-owned subsidiaries in France (Bezons), the USA, and China, with Asia representing 63% of 2023 revenue. Riber targets high-growth end-markets including 5G/6G VCSELs, datacom quantum-dot lasers for AI data-center interconnects, GaN power electronics, HgCdTe IR detectors for defense, and emerging silicon-photonics and quantum-computing applications, and partners with LAAS-CNRS (EPICENTRE lab) and NQCP (Niels Bohr Institute) to advance process automation and industrialization.
