Rigaku Holdings

What Rigaku Holdings does

Rigaku Holdings Corporation (TSE Prime: 268A) is a 75-year-old Japanese pure-play manufacturer of X-ray analytical and metrology instrumentation, operating through its wholly owned subsidiary Rigaku Corporation and a global footprint of 9 operating countries serving customers in 136 markets. The company builds a vertically integrated portfolio spanning X-ray diffraction (XRD, including high-resolution SmartLab and the proprietary DD/patented Direct Derivation method), wavelength- and energy-dispersive X-ray fluorescence (WDXRF/EDXRF, including ZSX Primus, NEX QC II, WaferX 310 and the Niton handheld line), total-reflection XRF (TXRF 3760, XHEMIS TX-3000), X-ray computed tomography (nano3DX, CT Lab), small-angle X-ray scattering (SAXS, including the CD-SAXS XTRAIA CD-3200T), electron diffraction (XtaLAB Synergy-ED, co-developed with JEOL), Raman spectroscopy (Progeny, CQL ID, Icon-X handhelds), and thermal analysis (TG-DTA, DSC, STAvesta, TMA). It also sells Electron Density Topography (EDT/MoleQlyze) instruments for biopharmaceutical imaging and life-sciences preclinical imaging (PET/SPECT/CT) acquired via MILabs B.V.

The business model is anchored on one-time capital equipment sales of high-end analytical instruments, complemented by recurring aftermarket service, support, replacement parts, and consumables tied to a multi-decade installed base, plus a growing software/analytics stream (notably through the Ai Diffract integration with Onto Innovation for hybrid metrology). Customers are sold via direct enterprise field sales through regional headquarters in Japan, the Americas (The Woodlands, TX), EMEA (Germany) and Asia-Pacific (Singapore), supplemented by channel partnerships (Shimadzu in Japan), co-development alliances (JEOL for electron diffraction, Onto Innovation for hybrid semiconductor metrology, imec for next-generation device metrology), and distributor relationships for handheld security Raman. End markets are diversified across eight primary verticals — semiconductor (front-end and advanced packaging), batteries and power electronics, pharmaceuticals and life sciences, materials/metals/mining/cement, academia and government research, public safety/forensics, electronics components, and food/cosmetics/cultural heritage — with approximately 70% of revenue generated overseas. The group employs more than 2,000 people and manufactures at the Akishima (Tokyo), Yamanashi (capacity doubled in 2025), Osaka, Kyoto (Nihon Instruments mercury analyzers), Auburn Hills MI, Dolní Břežany (Czechia), and Migdal HaEmek (Israel) facilities.

Recent strategic activity is dominated by the April 2026 announcement of a capital and business alliance with Onto Innovation Inc., under which Onto will acquire a 27% stake (61,123,436 shares) from Carlyle affiliate Atom Investment, L.P. for approximately USD 710 million (expected close H2 2026), a three-year co-development program with imec targeting an estimated USD 1 billion serviceable available market by 2030 in advanced AI semiconductor metrology with a 50% share goal, a December 2025 product launch of the ONYX 3200 dual-head microfocus X-ray metrology system (with FY2026 sales target of JPY 1.5 billion rising to JPY 3 billion in FY2027), and a portfolio of follow-on launches (XTRAIA MF-3400, XHEMIS TX-3000, NEX QC II Series, Icon-X handheld Raman). The holding company was IPO'd on the Tokyo Stock Exchange Prime Market on October 25, 2024.
