        DYCOM ANNOUNCES FISCAL 2004 FOURTH QUARTER EARNINGS AND PROVIDES
                    GUIDANCE FOR THE NEXT TWO FISCAL QUARTERS


Palm Beach Gardens, Florida, August 30, 2004--Dycom Industries, Inc. (NYSE
Symbol: "DY") announced its results today for the fourth quarter ended July 31,
2004. The Company reported net income for the quarter ended July 31, 2004 of
$17.1 million, or $0.35 per common share diluted, versus net income for the
quarter ended July 26, 2003 of $11.4 million, or $0.24 per common share diluted.
Total contract revenues for the quarter ended July 31, 2004 were $260.8 million
compared to total contract revenues of $182.9 million for the quarter ended July
26, 2003, an increase of 42.6 %.

For the year ended July 31, 2004, the Company reported net income of $58.6
million, or $1.20 per common share diluted, versus net income for the year ended
July 26, 2003 of $17.1 million, or $0.36 per common share diluted. Total
contract revenues for the year ended July 31, 2004 were $872.7 million compared
to total contract revenues of $618.2 million for the year ended July 26, 2003,
an increase of 41.2%. Included in the net income for the year ended July 31,
2004 was a nonrecurring gain of $11.4 million ($6.8 million net of tax) related
to the sale of long-term accounts receivable, and a charge of $2.3 million ($1.4
