Deep Intelligence Across Industries

Azbil is Japan's leading specialist in building and industrial automation. It sells measurement and control technology under its "human-centered automation" philosophy. It is the domestic market leader in building automation (BA), covering HVAC control, building management systems and energy services for large commercial buildings, data centres, hospitals and factories, including semiconductor fabs and their cleanrooms. Its Advanced Automation (AA) business supplies process instrumentation, control valves, controllers and MEMS-based sensors. Some of those MEMS products sit directly inside semiconductor manufacturing equipment: sapphire capacitance diaphragm vacuum gauges, mass flow controllers and micro-flow meters. Its Life Automation (LA) business makes gas and water meters and lifeline services. About 82% of revenue is earned in Japan. A large installed base generates recurring service revenue, which keeps margins high: FY2025 operating margin was 15.8% and the equity ratio was 76.1%. Since selling its Spanish pharmaceutical-equipment subsidiary in 2024, Azbil has focused on higher-margin automation and on growing in Southeast Asia, North America and China. Its FY2030 targets are ¥420 billion revenue and a 15.5% margin. **What the company does.** Azbil designs, manufactures, engineers, installs and maintains automation systems and devices that measure and control temperature, humidity, pressure, flow, combustion and energy. It works through three reporting segments: **Building Automation (BA):** BA held 52% of FY2025 sales. It supplies building management systems (BMS), HVAC controllers, valves, dampers, variable-air-volume (VAV) and room-pressure control, security and access integration, and energy-management services. Its customers are owners and operators of large buildings and industrial facilities, mainly in Japan and Asia. BA work divides into new buildings, existing-building retrofit, and services such as maintenance, multi-year service contracts, remote monitoring and energy optimisation. **Advanced Automation (AA):** AA held 37% of FY2025 sales. It covers process automation (distributed control systems, field transmitters, flowmeters, control valves and positioners for refining, petrochemical, chemical, pulp and paper, and utilities), factory automation (single-loop controllers, sensors, switches, combustion safety, thermal mass flow meters and controllers), and MEMS-based components. These include vacuum gauges and mass flow controllers used in semiconductor deposition and etch equipment. **Life Automation (LA):** LA held 11% of FY2025 sales. Its Lifeline field, through Azbil Kimmon, makes city-gas, LP-gas and water meters and offers Smart Metering as a Service (SMaaS). It also has a residential field (whole-house air conditioning) and a remaining domestic life-science engineering business. The European pharmaceutical-equipment arm, Azbil Telstar, was sold in October 2024. **Business model and revenue mix.** Azbil describes itself as solution-led. It sells products into projects and then captures decades of service and retrofit revenue from the installed base. The company does not break out product, service, subscription and licensing revenue in a standard way. Its disclosures and segment commentary show three things: - BA revenue is weighted towards engineering, service and retrofit work on existing buildings, including multi-year service contracts renewed in large blocks (as in FY2022 and Q1 FY2024). - AA revenue is mainly product revenue (instruments, valves, controllers and MEMS devices) plus maintenance and diagnostic services, such as valve diagnostics and online abnormality prediction. - LA revenue is mainly meter hardware tied to regulated replacement cycles, with SMaaS as an emerging recurring line. **Value-chain position.** Azbil sits between equipment OEMs and end users. In buildings it acts as controls contractor and system integrator, typically subcontracted by general contractors and mechanical contractors in Japan. In industry it supplies field devices and control systems directly or through distributors. In semiconductors it supplies two layers. At the facility layer it provides HVAC and environmental control of cleanrooms and utility plants. At the tool layer it sells MEMS sensors and flow devices to equipment manufacturers. **Customer types and end markets.** Customers include office and mixed-use developers, data-centre operators, hospitals, universities, hotels, public facilities, factories (semiconductors, electronics, automotive, food, pharmaceuticals), process plants (oil, gas, chemicals, steel, pulp and paper), gas utilities, water authorities and households. **Company description.** In its FY2025 disclosures, Azbil describes itself as practising "human-centered automation" in three markets: buildings (BA), industry (AA) and lifelines and living (LA). It frames the goal as contributing "in series" to a sustainable society. In May 2026 it adopted a new corporate Purpose, rendered in English as "Expanding Technological Frontiers, Unlocking Human Potential", together with a ten-year Vision. **Independent characterisation.** Azbil is best understood as a high-margin, cash-rich, Japan-centric installed-base franchise with a cyclical industrial arm attached. The BA franchise in Japan resembles a utility-like service business. It earned an 18.5% segment margin in FY2025, and its backlog of ¥98.8 billion at March 2026 covered more than seven months of BA sales. AA gives exposure to the semiconductor equipment and factory-automation cycle. LA is a low-margin, regulated-replacement business that management is restructuring. For the semiconductor fab supply chain, Azbil matters in two ways. It is a critical controls supplier for cleanroom environmental control in Japanese fabs, and its MEMS vacuum and flow components go into front-end equipment.

Brooks Instrument is one of the oldest specialists in precision fluid measurement and control. It is best known in the semiconductor supply chain as a maker of thermal and pressure-based mass flow controllers (MFCs), the devices that meter process gases into etch, deposition and epitaxy chambers. Since 1946 it has expanded from glass-tube rotameters into ultra-high-purity metal-sealed MFCs (the GF100 family), pressure-based MFCs (GP200), Coriolis low-flow controllers (Quantim QMC), direct-liquid-injection vaporizers, vacuum capacitance manometers and pressure controllers. It also serves biopharmaceutical, chemical, petrochemical, thin-film, fiber-optic, solar and research customers. The company says it has the world's largest installed base of MFCs. As part of ITW, it runs on the 80/20 front-to-back operating model and ITW's Customer-Back Innovation framework. In the semiconductor segment it is a credible Western alternative to Japanese leaders HORIBA and Fujikin. Brooks has invested in Asian capacity in Yongin (Korea) and Penang (Malaysia) and has brought precision machining in-house. Together these steps give it a supply chain spread across several regions, which suits fab and OEM customers who want more than one source. --- **What the company does.** Brooks Instrument designs, manufactures, calibrates and services instruments that measure and control the flow, pressure and vaporization of gases and liquids. Its core value proposition is accurate, repeatable and reproducible metering of fluids. This applies especially at low flow rates and in ultra-high-purity, corrosive, hazardous or sterile environments. **Company's own description.** Brooks describes itself as a world leader in precision fluid measurement and control technology. It says it provides instrumentation for flow, pressure and vapor delivery to customers in semiconductor and high-tech manufacturing, laboratories, pharmaceutical and biopharmaceutical production, fiber optics, thin-film manufacturing, solar cells, LED, alternative energy, oil and gas, chemical and petrochemical processing. It says its purpose is to "enable progress through precision". Its stated history and corporate materials stress customer-back innovation, ITW 80/20 discipline and entrepreneurial culture. **Parent's description of the segment.** ITW's Test & Measurement and Electronics segment produces equipment, consumables and related software for testing and measuring materials, structures, gases and fluids, as well as equipment and consumables for electronic subassemblies and microelectronics. Brooks is the segment's gas- and fluid-measurement franchise. Its sister brands include Instron, Buehler, Avery Weigh-Tronix, Magnaflux, Despatch, MPM, Electrovert, Camalot, Simco-Ion, Texwipe and Loma. **Business model and revenue model.** **Products (instruments):** Characterization: The dominant source of revenue. MFCs, meters, controllers, vaporizers, rotameters and pressure/vacuum devices are sold as discrete hardware. **Aftermarket and service:** Characterization: Calibration, repair, field service and spares, delivered through 9 service centers and 20 regional spares locations. The large installed base generates recurring replacement and recalibration demand. **Software:** Characterization: Diagnostic and configuration tools (Brooks Expert Support Tool, BEST; BCAT verification and recalibration software). These are generally bundled to support hardware rather than sold as subscriptions. **Licensing:** Characterization: Occasional. For example, its direct liquid injection (DLI) vaporizer technology was licensed to Ceres Technologies in January 2019. **Revenue mix by stream:** Characterization: Not publicly disclosed **Value chain position.** Brooks sits in tier two of the semiconductor equipment supply chain. It sells MFCs to wafer-fab equipment OEMs (etch, CVD/ALD, PVD and epitaxy toolmakers) and to gas-panel and gas-delivery-system integrators. It also sells directly to fabs for spares and replacements. The MFC is the central active component of a "gas stick" within the gas delivery system. Brooks has been recognized by Applied Materials with a Supplier Excellence Award (January 2023). In life sciences, Brooks supplies bioreactor and bioprocess-skid OEMs; Cytiva's X-platform bioreactor uses SLA Series Biotech MFCs. In industrial markets, it sells through distributors and representatives such as Cross Company in the US. **Customer types.** Semiconductor OEMs and fabs; LED/compound-semiconductor (MOCVD) toolmakers; thin-film, solar, optical-fiber and glass-coating producers; biopharmaceutical OEMs and end users; chemical, petrochemical and refining operators; fuel-cell, hydrogen and catalyst researchers; university and national laboratories; aerospace (NASA leak-testing applications). **End-markets served.** Semiconductor and electronics (the largest growth vector); life sciences and bioprocessing; chemical/petrochemical and oil and gas; energy transition (hydrogen, fuel cells, carbon nanotubes); general industrial and research. **Independent characterization.** Brooks is a mid-sized, high-precision instrument franchise. Its economics are shaped by two forces. The first is the semiconductor capital-equipment cycle, which drives demand for metal-sealed MFCs. The second is a steadier, diversified industrial and life-sciences installed base that supports aftermarket revenue. The company's distinctive assets are its multi-gas/multi-range programmability (MultiFlo), pressure-transient-insensitive control, its legacy installed base under the Brooks, UNIT Instruments, Tylan, Key Instruments and Celerity brands, and its US/Hungary/Korea/Malaysia manufacturing network. Its main structural challenge is scale: Japanese incumbents hold dominant shares of semiconductor MFC revenue.
