As always, customers should review their payment card account statements closely and report any unauthorized charges to their card issuer immediately.

Hyatt Hotels Corporation (NYSE: H) today announced that it recently identified malware on computers that operate the payment processing systems for Hyatt-managed locations. As soon as Hyatt discovered the activity, the company launched an investigation and engaged leading third-party cyber security experts.

The investigation is ongoing, and updates will be posted to www.hyatt.com/protectingourcustomers. Hyatt has taken steps to strengthen the security of its systems, and customers can feel confident using payment cards at Hyatt hotels worldwide.

As always, customers should review their payment card account statements closely and report any unauthorized charges to their card issuer immediately. Payment card rules generally provide that cardholders are not responsible for unauthorized charges that are timely reported.

The term "Hyatt" is used in this release for convenience to refer to Hyatt Hotels Corporation and/or one or more of its affiliates.
