Hotelier Marriott International disclosed in a filing with the Securities and Exchange Commission on Tuesday that the U.K.’s Information Commissioner’s Office intends to fine it for breaches of the EU’s data protection law.

Following what the agency termed “an extensive investigation,” the ICO, the U.K.’s independent regulator for data protection and information rights law, has issued a notice of its intention to fine Marriott £99,200,396 (roughly U.S. $124 million) for infringements of the General Data Protection Regulation.
