Baltimore, MD (July 26, 2006) - Under Armour, Inc. (NASDAQ: UARM) today announced financial results for the second quarter ended June 30, 2006.

Net revenues increased 63.3% in the second quarter to $80.0 million compared to net revenues of $49.0 million in the second quarter of 2005. Apparel revenues for Men's, Women's, and Youth increased 31.0% to $58.0 million. Footwear revenues, which consist of football cleats and slides, were recorded for the first time in the second quarter of 2006 and totaled $15.6 million.

Second quarter net income increased 32.5% to $2.4 million compared to $1.8 million in the same period of 2005. Diluted earnings per share was $0.05, on weighted average common shares outstanding of 49.4 million compared to $0.03 per share on weighted average common shares outstanding of 37.5 million in the second quarter of the prior year.

"We accomplished the goals we set for the quarter and in the process exceeded our own expectations," stated Kevin A. Plank, Chairman, CEO, and President of Under Armour, Inc. "We continued to drive revenue growth in our apparel business while building the foundation for a broader revenue base in international markets and in new product categories, such as footwear. We achieved these strategic growth goals while also accomplishing a key operational objective for the quarter, the implementation of SAP. This implementation provides us with the infrastructure needed to support our growing business."

Mr. Plank added, "The highlight of the quarter had to be the launch of football cleats. Our Click Clack™ marketing campaign created an extraordinary amount of momentum for the brand while the performance of the product has further validated our authenticity on the field. We believe the door is now open for us to apply Under Armour technology to additional athletic footwear categories."

Apparel revenues grew 31.0% for the quarter due to continued strength in the Men's and Women's business. Growth in Men's was driven by the golf, training, running, and compression categories as well as the continued expansion of the brand within existing retail doors. Revenue growth in the Women's fitness, training, and compression categories increased as the brand enhanced its presence on the retail floor and continued to focus marketing efforts on the female athlete.

Gross margin was 47.8% compared to 50.1% in last year's second quarter. As expected, gross margin was impacted by several factors, primarily the introduction of cleated footwear, which has margins lower than current apparel margins.

Selling, general and administrative expenses were 43.6% of net revenues in the second quarter of 2006 compared to 42.7% in the same period of the prior year. The Company had previously stated its commitment to a marketing budget of 10% to 12% of net revenues for the full year but indicated that it would undertake incremental marketing spend in the second quarter to support its footwear launch. Marketing expense for the second quarter was 13.2% of net revenues compared to 12.8% in the same period last year.

Increasing Outlook for 2006

Due to the strength of the second quarter, ongoing momentum in its apparel business, and favorable business trends, Under Armour is increasing its outlook for 2006.

The Company now expects annual net revenues in the range of $400 million to $410 million, a 42% to 46% increase over 2005, and annual net income in the range of $34 million to $35 million, which represents a 72% to 78% increase from 2005. The Company continues to expect fully diluted weighted average shares outstanding of approximately 50 million for 2006.
