Baltimore, MD (February 1, 2007) – Under Armour, Inc. (NYSE: UA) today announced financial results for the fourth quarter and year ended December 31, 2006.

Net revenues increased 55.0% in the fourth quarter to $135.3 million compared to net revenues of $87.3 million in the fourth quarter of 2005. Growth in apparel revenues accounted for $35.6 million of the year-over-year increase in net revenues for the quarter. Additionally, the Company reported $9.3 million in footwear revenues, largely driven by its launch into baseball and softball cleats.

Fourth quarter net income increased 69.4% to $11.9 million compared to $7.0 million in the same period of 2005. Diluted earnings per share was $0.24, on weighted average common shares outstanding of 49.8 million compared to $0.08 per share on weighted average common shares outstanding of 44.1 million in the fourth quarter of the prior year. The Company received a $1.0 million benefit to net income, or $0.02 per diluted share, as a result of the impact of state tax credits previously disclosed by the Company.

"In the third quarter, we reported our highest revenues in our 11 year history, and in the fourth quarter, we beat that record once again," stated Kevin A. Plank, Chairman and CEO of Under Armour, Inc. "The 55% growth in the top line for the quarter was matched with significant improvements in gross margin, and the strength of our business reflects our continued ability to connect with the athlete and to create innovative products that drive demand. We continue to grow our core product offering while at the same time leveraging our on-field authenticity to enter new product categories. Our successful launch of baseball and softball cleats is the latest manifestation of that strategy."

Growth in apparel revenues accelerated in the quarter, increasing 43.2% over the prior year. The Compression and Training categories continued to drive revenue growth across the Men's, Women's, and Youth businesses as the Brand gained additional space on retail floors. Apparel revenues also benefited from an increase in average selling price as the Company expanded the breadth of its product offering.

Gross margin for the quarter increased to 50.6% compared to 48.7% in the prior year, primarily driven by benefits from the Company's sourcing initiatives as well as an increased percentage of sales in higher margin product. Selling, general and administrative expenses were 37.5% of net revenues in the fourth quarter of 2006 compared to 34.0% in the same period of the prior year. Marketing expense for the fourth quarter was 12.6% of net revenues compared to 8.6% in the prior year due to continued opportunistic investments made to support the Brand.

Review of Full Year Operating Results

Net revenues for the year increased 53.2% to $430.7 million from $281.1 million in 2005. Net income increased 97.7% to $39.0 million compared to $19.7 million in the prior year, within the range of the Company's previously provided outlook of $38.5 million to $39.5 million for the year. Diluted earnings per share was $0.79, on weighted average common shares outstanding of 49.6 million compared to $0.36 per share on weighted average common shares outstanding of 39.7 million in 2005. The Company received a $3.3 million benefit to net income, or $0.07 per diluted share, as a result of the impact of state tax credits previously disclosed by the Company.

Apparel revenues grew 42.5% in 2006 due to increased strength in the Men's, Women's, and Youth businesses. The launch into footwear contributed $26.9 million to net revenues for the full year.

Gross margin in 2006 increased to 50.1% compared to 48.3% in the prior year primarily due to the Company's sourcing initiatives and an increase in its percentage of sales from higher margin product. Selling, general and administrative expenses were 36.8% of net revenues in 2006 compared to 35.6% in the prior year. The increase reflects the Company's continued investments in Marketing and growth initiatives as well as increased costs associated with being a public company. The Company had previously stated its commitment to a marketing budget of 10% to 12% of net revenues for the full year. Marketing expense for the year was 11.2% of net revenues compared to 10.8% in 2005. Income from operations as a percentage of net revenues in 2006 increased to 13.3% from 12.7% in the prior year.

Mr. Plank added, "We are proud of our accomplishments in our first full year as a public company. We continue to move consumers away from cotton by educating them on the benefits of technical performance apparel. Our apparel revenue growth accelerated in 2006, growing at 43% for the year compared to 35% in the year prior. This growth has allowed us to invest in the future of our company, and we will continue to make key investments to evolve the category of performance in apparel and footwear and to tell the performance story to consumers across the globe."

The Company anticipates fully diluted weighted average shares outstanding of approximately 50.5 million for 2007.

"While we have achieved outstanding financial performance since becoming a public company, we believe the greatest opportunity for the Brand lies ahead, which is why we continue to invest in new markets and product categories," stated Wayne Marino, Executive Vice President and Chief Financial Officer of Under Armour, Inc.
