Federman & Sherwood Announces Settlement of Sonic Corporation Data Breach Litigation

A Settlement has been reached with Sonic Corp. (“Sonic”) in a class action lawsuit pending in the United States District Court for the Northern District of Ohio styled In re:  Sonic Corp. Customer Data Breach Litigation, Case No. 1:17-md-02807-JSG.  The lawsuit alleged claims against several Sonic entities relating to a data breach arising out of a third-party cyber-attack in 2017 that targeted the point of sale systems of Sonic Drive-In locations in an effort to steal customer payment card information (the “Data Breach”).  Sonic has denied all of the claims in the lawsuit. The Settlement does not establish who is right, and is not an admission of fault, but rather reflects a compromise to end the lawsuit.

The Settlement includes all residents of the United States of America who made a purchase at any one of the 325 impacted Sonic Drive-In locations and paid using a credit or debit card from April 7, 2017 through October 28, 2017 (the “Relevant Time Period”).  You may view the impacted Sonic Drive-In locations at
