Pursuant to a stockholders' agreement among GMS Inc. (the "Company") and certain stockholders of the Company, the Reporting Person has agreed to vote all of his shares of common stock to elect one director nominated by AEA GMS Holdings LP for so long as AEA GMS Holdings LP and its affiliates own at least 10% of the Company's outstanding common stock. Accordingly, the Reporting Person is a member of a Section 13(d) "group" with AEA GMS Holdings LP and the other stockholders of the Company disclosed in a Schedule 13G filed with the Securities and Exchange Commission on behalf of the Reporting Person on February 14, 2017. As of the date hereof, the members of this Section 13(d) group collectively owned more than 10% of the Company's outstanding common stock. The Reporting Person disclaims beneficial ownership of the shares of common stock of the Company beneficially owned by the other members of the Section 13(d) group.
