Net revenues increased 15% in the first quarter of 2010 to $229.4 million compared with net revenues of $200.0 million in the first quarter of 2009.

First quarter apparel net revenues increased 31% to $172.6 million compared with $132.2 million in the same period of the prior year, driven by strong growth in the Men's, Women's, and Youth apparel businesses. Direct-to-Consumer net revenues grew 73% year-over-year during the first quarter driven by strong growth in both the Factory House stores and Web business. Footwear net revenues in the first quarter of 2010 were $43.0 million compared with $56.9 million in the first quarter of 2009. The Company had previously indicated that Running and Training footwear revenues were expected to decline in 2010 compared with 2009.

Kevin Plank, Chairman and CEO of Under Armour, Inc., stated, "We delivered solid top line growth of 15% in the first quarter as we continued to bring the performance story to new athletes across sports, gender and geographies. Our apparel net revenues increased 31% with strength in both the wholesale and Direct-to-Consumer channels, evidence the Brand still has tremendous growth opportunities."

For the first quarter, operating income rose 72% to $13.6 million compared with $7.9 million in the prior year's period. Gross margin for the first quarter of 2010 increased to 46.9% compared with 44.6% in the prior year's quarter primarily due to improved apparel margins and increased sales in the higher margin Direct-to-Consumer channel. Selling, general and administrative expenses as a percentage of net revenues increased to 41.0% in the first quarter of 2010 compared with 40.6% in the prior year's period as a result of increased investments in product creation and supply chain as well as continued expansion of the Factory House stores.
