Tokyo, Japan - January 19, 2026
Yokogawa Electric Corporation (TOKYO: 6841) announces that it has increased its strategic investment in Semantum Oy, a Finnish company that provides digital solutions and services in areas such as industrial plant data modeling, simulation, optimization, and engineering automation. With this investment, Semantum will become an affiliated company of the Yokogawa Group.
Yokogawa first invested in Semantum in 2019, and the two companies jointly developed the OpreX™ Data Model Broker, a product in Yokogawa's OpreX Connected Intelligence lineup. OpreX Data Model Broker automatically verifies the consistency of data in different plant designs and instrumentation systems and enables their inter-utilization by applying ontology*, an AI technique, in database operation and management.
This investment will enable Yokogawa to expand its DX capabilities by leveraging Semantum's software development expertise to elevate the company's digital twin and semantic data modeling technologies. At the same time, it will also allow Semantum to accelerate its geographical and market expansion plans, capturing new markets and expanding existing business in the fast-growing digitalization and systems simulation market. The investment is part of Yokogawa's strategic M&A and partnership initiatives to strengthen its digital portfolio.
Kazuhiko Takeoka, a Senior Vice President & Executive Officer and head of the Digital Solutions Headquarters at Yokogawa Electric, commented, “We welcome Semantum to the Yokogawa family. This deepened relationship will allow us to integrate Semantum's capabilities more deeply into our OpreX solutions, providing our customers with unparalleled operational insight and efficiency.”
Antti Villberg, Managing Director of Semantum, added, “Becoming an affiliate of the Yokogawa Group marks an exciting new chapter for Semantum. This partnership strengthens our ability to scale our business globally and accelerates our mission to deliver innovative engineering automation and digital twin solutions to customers worldwide.”
