This Amendment No. 1 to Schedule 13D (this “Amendment”) amends and supplements the Schedule 13D filed August 28, 2015 (the "Original Schedule 13D"), by Stuart M. Essig, Stuart M. Essig 2007 Family Trust and Essig Enright Family Foundation (the “Reporting Persons”) relating to the common stock, par value $0.01 per share, of SeaSpine Holdings Corporation (“SeaSpine” or the "Issuer"). As of the date of this report, the Filing Persons beneficially own less than 5% of the outstanding shares of the Issuer. Consequently, this Amendment constitutes the final amendment to the Original Schedule 13D and an exit filing for the Reporting Persons. Except as set forth herein, this Amendment does not modify any of the information previously reported by the Reporting Persons in the Original Schedule 13D. Unless otherwise indicated, all capitalized terms used herein have the meanings ascribed to them in the Original Schedule 13D.
