(Adds details, share move)
May 15 (Reuters) - Home Depot Inc's sales at established stores missed Wall Street forecasts for the first time in seven quarters, as cooler weather in some U.S. states led to a slower-than-expected start to the spring selling season.
Shares of the No. 1 U.S. home improvement chain, which have risen about 22 percent in the past 12 months, fell 2.4 percent to $186.54 in premarket trading on Tuesday.
U.S. homebuilding data from March suggested that construction activity may be slowing, as single-family homebuilding — which accounts for the biggest share of the housing market — fell 3.7 percent.
Cooler-than-usual weather in some parts of the country also hit sales, leading to weak customer spending on spring-season products.
Home Depot said customer transactions dipped 1.3 percent in the first quarter ended April 29.
Sales at Home Depot stores open for more than a year climbed 4.2 percent, missing analysts' average estimate of a 5.38 percent rise, according to Thomson Reuters I/B/E/S.
Net earnings rose to $2.40 billion or $2.08 per share in the first quarter, from $2.01 billion or $1.67 per share a year earlier. Analysts were expecting earnings of $2.05 per share.
Net sales rose 4.4 percent to $24.95 billion, but fell short of expectations of $25.16 billion. (Reporting by Aishwarya Venugopal in Bengaluru; Editing by Sai Sachin Ravikumar)
