Apparel and footwear retailer Genesco Inc on Thursday posted a steep fall in first quarter net profit amid flat sales at most of its chains in a weak retail environment. The Tennessee-based operator of around 1,000 stores under banners such as Journeys, Journeys Kidz, Johnston & Murphy, Jarman and Underground, posted net income of 3.3 million, or 15 cents a share, versus $8.2m, or 33 cents a share, in the year-ago period.
