Update regarding unauthorised access to technology systems

InterContinental Hotels Group PLC (IHG or the Company) provides an update further to its announcement on 6 September that parts of the Company's technology systems had been subject to unauthorised activity causing disruption to IHG's booking channels and other applications.

Following a period of disruption, by Wednesday 7 September IHG had re-activated its booking websites and mobile app together with most of its other booking channels and revenue-generating systems. Subsequently, service at our Reservation and Customer Care call centres has been recovered and all our systems restored. During the disruption in our central systems, IHG-branded hotels continued to operate and were able to take reservations directly.

We have continued to carry out additional steps as part of our recovery and assurance plans to review and further enhance our security measures. External specialists were engaged to investigate the incident, and no evidence of unauthorised access to systems storing guest data has been identified. We have also reported the criminal activity to law enforcement. We continue to work closely with our hotels and owners throughout this time.
