The group earns revenue from data access and analysis, payer-support services, healthcare software and consulting, medical-institution services, and remote diagnostic imaging. In the year ended March 2026, health big data generated more than four-fifths of segment revenue, with the remainder mainly from telemedicine services that match medical imaging requests with radiologists.
