About
Oracle Health is the healthcare technology business unit of Oracle Corporation (NYSE: ORCL) — providing electronic health records (EHR), clinical workflow management, health information exchange, revenue cycle management, and population health analytics to hospitals, health systems, physician practices, ambulatory clinics, and government health agencies globally — operating as the rebranded Cerner Corporation following Oracle's $28.3 billion acquisition of Cerner in June 2022, the largest acquisition in Oracle's history. Oracle Health's EHR platform (the Cerner Millennium clinical information system) powers clinical documentation, physician order entry, nursing workflows, medication administration, and patient care coordination for approximately 30% of US hospitals — making Oracle Health the second-largest EHR vendor in the US hospital market after Epic Systems. A major integration program is underway to migrate Cerner's clinical applications to Oracle Cloud Infrastructure (OCI), enabling Oracle Health to leverage Oracle's cloud scale, Oracle's AI capabilities (generative AI for clinical documentation, ambient listening for physician notes), and Oracle's database performance advantages for health record analytics. Oracle Corporation named Clay Magouyrk and Mike Sicilia as co-CEOs in 2025 (replacing Safra Catz), positioning Oracle Health's clinical platform to benefit from the next-generation Oracle leadership team's emphasis on cloud and AI transformation.
