Reason for Share Acquisition

SmartViser provides automated test solutions to mobile network operators, device manufacturers, and others. Its business encompasses performance evaluation of mobile networks and devices, functional testing, quality monitoring, and compliance with EU smartphone energy labelling regulations (EEI — Energy Efficiency Index). In March 2025, Anritsu acquired a 32.72% stake in SmartViser and has since collaborated with SmartViser while maintaining operational independence. By making SmartViser a consolidated subsidiary, Anritsu will be able to combine SmartViser’s expertise in test automation and efficiency with Anritsu’s own advanced test solutions in telecommunications. This is expected to expand business opportunities not only in the smartphone market but also across a wide range of industries using communication technologies, including private networks, mission-critical networks, and the automotive sector. With this initiative, Anritsu aims to help achieve a carbon neutral and smart society.
