Yokogawa Electric
A Japanese industrial-automation company that builds distributed control systems (DCS) for large refining, chemical, power and LNG plants. Its CENTUM, the world's first DCS launched in 1975, runs at over 30,000 facilities in more than 100 countries. About 94% of revenue comes from the control (IA&C) business, with oil and gas as the core market. FY2025 (ended March 2026) revenue was about ¥595.0 billion with ¥87.0 billion operating income.

Yokogawa's thesis is installed-base lock-in. Since the first DCS (CENTUM, 1975), control systems in 30,000+ facilities across 100+ countries can't be swapped easily due to switching cost and safety certification, so the control (IA&C) business — 94% of sales — behaves like recurring/service revenue. It is exposed to oil & gas capex, its largest market, and the LNG cycle, while reinforcement-learning AI control (e.g., 35 days of unmanned autonomous operation at a JSR plant) differentiates and extends it. Risks are softening energy capex and the pace of autonomous-control adoption. Graph propagation: capex and operations of large-plant customers like Aramco, ExxonMobil and JSR set demand.
