A deficient performance by the Brand Anthropologie has weighed adversely on Urban Outfitters, the clothing and accessories retailer whose net income and revenue both fell far short of Wall Street estimates. Shares of Urban Outfitters tumbled in aftermarket trading on Monday, losing 15.6% to $34.36.

The Philadelphia-based firm's net income fell 13% or 25 cents per share, to $32.8 million, as cost of goods sold increased by 10%. Its revenue rose 8% to $739 million but the analysts had expected a profit of 30 cents per share and revenue of $760.5 million.

The fall in the quarterly sales is attributed to a downfall of net sales under the Anthropologie brand which rose barely by 3.8% to $311.4 million, the slowest pace in 11 quarters. Comparably, the retail net sales at Free People, the company's smallest brand, rose 17% in the quarter, whereas the Urban Outfitters had a rise of 5% and a meager 1% rise in Anthropologie.

The company stated that the first-quarter results were dragged down by higher expenses. It was also informed that the Urban Outfitters spent more on marketing and technology and additionally delivery and order fulfillment costs increased, thus profit margins for the Urban Outfitters brand were down compared to last year. Not to miss, the Urban Outfitters' sales have been affected drastically by the increasing competition from fast fashion brands such as H&M, Zara and Forever 21.

The company agreed that the performance of Anthropologie is a 'disappointment' and said that it expects more discounts in the business in the second quarter as it tries to attract young women. The company has been overhauling stores and merchandise at its namesake brand to fight a slowdown in sales. The company's brand, Anthropologie caters to women aged 28-45 years.

At the end of first fiscal quarter on April 30, the company had 238 Urban Outfitters stores, 208 Anthropologie Group stores, and 106 Free People stores.
