September 5, 2017

PALM BEACH GARDENS, Fla., Sept. 5, 2017 /PRNewswire/ -- Dycom Industries, Inc. (NYSE: DY) announced today that its Board of Directors has approved a change in the Company's fiscal year end from July to January. Beginning with a six month transitional period ending January 27, 2018, the Company's fiscal year will end on the last Saturday of January. The Company will file a transition report on Form 10-K containing audited financial statements for the six month period from July 30, 2017 to January 27, 2018. After the transition period, each fiscal year will consist of either 52 or 53 weeks of operations (with the additional week of operations occurring in the fourth fiscal quarter). The Company's 2019 fiscal year will commence on January 28, 2018 and will consist of 52 weeks.

The change in fiscal year end better aligns the Company's fiscal year with the planning cycles of the Company's customers. Year-over-year quarterly financial data will continue to be comparative to prior periods as the months that comprise each fiscal quarter in the new fiscal year are the same as those in the Company's historical financial statements.
