Baltimore, MD (July 29, 2008) – Under Armour, Inc. (NYSE: UA) today announced financial results for the second quarter ended June 30, 2008.

Net revenues increased 30.0% in the second quarter of 2008 to $156.7 million compared to net revenues of $120.5 million in the second quarter of 2007. Based on the seasonality of net revenues and the timing of marketing and other investments, the Company had previously indicated that earnings would be more heavily weighted to the back half of 2008 relative to 2007. Second quarter net income was $1.4 million compared to $5.7 million in the same period of 2007. Diluted earnings per share for the second quarter of 2008 was $0.03 on weighted average common shares outstanding of 49.8 million compared to $0.11 per share on weighted average common shares outstanding of 49.9 million in the second quarter of the prior year.

For the first six months of 2008, net revenues increased 28.2% to $314.0 million from $244.9 million in the prior year. These results were at the high-end of the Company's previously provided outlook of 26% to 28% net revenue growth for the first half of the year. Diluted earnings per share for the first six months of 2008 was $0.09, compared to the Company's previous outlook of $0.06 for the first half of the year.

"Our 30% net revenue growth in the quarter illustrates our ability to make the right investments in the Company to build significant growth platforms and execute our plan," stated Kevin A. Plank, Chairman and CEO of Under Armour, Inc. "The strength of our Brand, the commitment of our team, and our ability to introduce new and innovative products to today's athlete keeps us excited each and every day about the opportunities for our Company."

Mr. Plank continued, "On May 3rd, we entered the next chapter of our growth story with the launch of our Performance Training Footwear. We developed a product that met the specific needs of our athlete, successfully generated excitement in the marketplace and brought consumers to the Training category. The response to our Performance Trainer launch has been tremendous from both a consumer acceptance and retail sell-thru perspective. It is that success that gives us the confidence to enter the Running Footwear business in the first half of 2009. We are entering the category with great momentum from our Performance Trainer launch and are doing so with a strong point of view on what Under Armour will mean to runners."

Apparel net revenues for the second quarter rose 10.3% to $96.2 million compared to $87.2 million in the same period of the prior year. As reported last quarter, the Company implemented a new warehouse management system in its distribution center in April 2008. Due to the systems switch, some customers elected to take shipments at the end of March that were originally planned for the beginning of April. This impacted apparel growth in the second quarter, which is typically the lowest apparel revenue quarter for the year. For the first six months of 2008, apparel net revenues increased 18.1%, and the Company remains comfortable with achieving over 20% growth in apparel for the full year. With the launch of Performance Training Footwear during the quarter, footwear revenues increased 128.8% to $46.0 million from $20.1 million in the second quarter of 2007.

Gross margin for the second quarter of 2008 was 45.3% compared to 49.0% in the prior year's quarter. The decline in gross margin was primarily driven by the higher proportion of footwear sales in the quarter, which have lower gross margins than apparel. Footwear net revenues represented 29% of total net revenues in the second quarter of 2008 compared to 17% in the same period of the prior year. Selling, general and administrative expenses were 43.2% of net revenues in the second quarter of 2008 compared to 42.2% in the prior year. Marketing expense for the second quarter of 2008 was 14.4% of net revenues compared to 13.5% in the prior year's period. The Company still expects to invest in marketing at the high-end of the range of 12% to 13% of net revenues for the full year.

Balance Sheet Highlights

Inventory totaled $183.9 million at June 30, 2008, compared to $166.1 million at December 31, 2007 and $128.8 million at June 30, 2007. As the Company had anticipated, the inventory growth rate in the second quarter of 2008 marked a deceleration from the inventory growth reported for the first quarter. Inventory in the second quarter of 2008 increased 42.8% year-over-year. Based on its inventory management strategy and supply chain initiatives, the Company continues to expect inventory to grow in-line with net revenues by the end of the third quarter and inventory to grow at a rate below net revenues by the end of the year. Cash and cash equivalents were $13.3 million at June 30, 2008 compared to $40.6 million at December 31, 2007 and $25.7 million at June 30, 2007. The Company had $5.0 million in borrowings outstanding under its $100 million revolving credit facility at June 30, 2008.

Outlook for 2008

As previously stated, the Company is targeting a 25% compounded annual growth rate in net revenues from 2007 to 2010. For 2008, the Company continues to expect annual net revenues in the range of $765 million to $775 million, an increase of 26% to 28% over 2007. However, based on the results in the second quarter, the Company is raising its 2008 income from operations outlook to $104.5 million to $105.5 million, an increase of 21% to 22% over 2007. The Company had previously estimated 2008 income from operations to be in the range of $103.5 million to $104.5 million.

With second half footwear shipments predominantly in the fourth quarter and continued strong growth anticipated in the Direct-to-Consumer channel, which is also most pronounced in the fourth quarter, net revenues for the third and fourth quarters of 2008 are expected to be relatively similar. Coupled with the timing of planned investments in the second half, fourth quarter earnings are expected to be the highest of the year as compared to 2007 when earnings peaked in the third quarter.

Mr. Plank concluded, "Under Armour is a growth company, and we remain excited about the enormous opportunities ahead. We expanded the breadth of our leadership team with the addition of David McCreight as President, successfully launched into non-cleated footwear, announced our entry into the Running Footwear business, and are seeing growth in our Women's and Youth apparel businesses outpace Men's with all categories on-track to hit full year projections. We are building a platform business with multiple growth levers and are setting the stage for continued growth in 2009 and beyond."
