Oracle's application revenue growth has slowed in recent quarters, underperforming both the overall software market and competitor SAP. This is partly due to external factors like currency fluctuations, but also appears to be related to conflicts between Oracle's Applications Unlimited policy and its Oracle Fusion Applications. Under Applications Unlimited, clients can stay on existing apps indefinitely, providing little incentive to migrate to Fusion. As a result, adoption of Fusion has been low. To restore app revenue growth, Oracle will need to increase interest in Fusion while still supporting existing apps.
