Net income fell to $177 million, or 47 cents per share, for the three months ended Aug. 27, down from $254 million or 60 cents per share last year. Analysts expected earnings of 52 cents per share, according to a survey by FactSet.
Revenue edged up to $11.35 billion from $11.34 billion. But analysts expected $11.47 billion.
Revenue in stores open at least one year fell 2.8 per cent during the quarter. The measure is a key gauge of a retailer's financial health because it excludes stores that open or close during the year.

Analysts, who typically exclude one-time items from their estimates, expect earnings of $3.45 per share.
