SUPPLEMENT TO
DEFINITIVE PROXY STATEMENT AND
NOTICE OF ANNUAL MEETING OF SHAREHOLDERS

for the Annual Meeting of Shareholders to be held on
Tuesday, May 21, 2019

On April 11, 2019, Dycom Industries, Inc. (the “Company”) filed a definitive proxy statement (the “Proxy Statement”) with the Securities and Exchange Commission (“SEC”), which was distributed in connection with the Company’s Annual Meeting of Shareholders to be held on May 21, 2019 (the “Annual Meeting”).

The Company is providing this supplement (“Supplement”) solely to correct an inadvertent omission in the Proxy Statement regarding the biography of Anders Gustafsson, a member of the Board of Directors (the “Board”) of the Company and a director nominee for election to the Board at the Annual Meeting.

Mr. Gustafsson’s biography, which is included on page 9 of the Proxy Statement, did not state that he became a member of the Board of Directors of International Paper Company effective March 1, 2019. Prior to accepting that directorship, and prior to the Board’s decision to nominate Mr. Gustafsson for election to the Board at the Company’s Annual Meeting, Mr. Gustafsson informed the Company’s Chairman of the Board and its Chair of the Corporate Governance Committee of the Board of this new directorship in accordance with the Company’s Corporate Governance Guidelines.
