If you want to truly understand Under Armour (UAA 1.81%), there's only one thing you need to know: Founder and CEO, Kevin Plank, will not stop until he catches Nike (NKE -1.26%) as the biggest sports-apparel and footwear company in the world. Plank is akin to Jeff Bezos of Amazon.com, or Steve Jobs, formerly of Apple. These types of personalities are solely focused on one goal, and they're highly determined and relentless. Investing with them often proves to be very successful.

Under Armour's latest move to increase brand exposure is a wise one. It also demonstrates how the company is willing to go well beyond expectations. 

Olympic sponsorships
The Winter Olympics will take place in February. It's likely that you will be watching some of the events. If you happen to watch the U.S. Speedskating Team, U.S. Bobsled & Skeleton Team, or Canadian Snowboard Team, pay close attention to the attire being worn. You will notice that it's Under Armour's moisture-wicking technology. This gives Under Armour potential for increased brand exposure on a global level. 

Under Armour had already sponsored the U.S. Bobsled & Skeleton Team, but the U.S. Speedskating Team and Canadian Snowboard Team are first-time sponsorships, tripling the brand's exposure potential compared to previous Olympics. Of course, if one of these teams wins a gold medal, then exposure is greatly enhanced.

Keep in mind that while Under Armour is everywhere domestically, being worn by kids, men, and women, including non-athletes, it's well behind Nike globally. This year's Olympics could act as a springboard for global growth. 

If you look a little deeper into this story, you will see what makes Under Armour a unique and special company.  

Extremely impressive technological advancements
When it comes to the Nike versus Under Armour competition, Under Armour knows it's an underdog. Under Armour has a market cap of $9.6 billion, well shy of Nike's $68.5 billion market cap. But this is exactly what motivates Under Armour to make bold moves. This boldness has proved to have positive effects over the past several years. Take a look at Under Armour's top-line growth since 2009:

But that's still not enough for Plank and Under Armour. Plank recently displayed his boldness by approaching Lockheed Martin (LMT 1.71%) for its engineering expertise. Plank wanted Lockheed Martin to help create the best speedskating suit in the world, as aerodynamically advanced as possible.

Lockheed Martin agreed, and after high-speed cameras taking pictures of the skaters in motion during practice as well as computational fluid dynamic models to analyze air flows around skater body positions, the U.S. Speedskating Team will now be wearing the best, fastest, and most aerodynamic speedskating suits in existence. This fits right into Under Armour's tag line of "Making Athletes Better." 

Another example of Under Armour's highly innovative ways, the company noticed that athletes would often unzip their suits at the neck due to discomfort, but this would slow them down. What did Under Armour do? It created a wraparound zipper that avoids the throat area. Sounds simple, but no one else had thought of it in the past.

Growth begets growth
Under Armour's highly innovative nature might concern Nike, but what Nike should really be concerned about is that as Under Armour's top line continues to grow, so does its marketing power. Under Armour uses 11% of revenue annually for marketing. The Olympic sponsorships for this year wouldn't have been possible without consistent top-line growth over the past year.

If these sponsorships prove to be successful, by global brand presence and sales increasing, then Under Armour's top line will continue to grow, and it will have an opportunity to spend more money (11% of that revenue annually) on marketing and sponsorships in the future.

The bottom line
Nike is one of the most well-run and fiscally sound companies in the world. It has enormous brand power globally, it continues to see steady growth, and it currently offers a dividend yield of 1.2%. Under Armour doesn't pay a dividend, but that's only because it's using the majority of its cash flow for reinvestment in its business.

Barring any economic calamities, Under Armour's top line should continue to grow. The company's Olympic sponsorships should act as positive catalysts, and Under Armour's highly innovative nature gives it strong potential to increase market share from Nike over the long haul.
