Wesco Aircraft Holdings (NYSE:WAIR) makes hardware for the aircraft industry. This includes mostly engineered fasteners as well as bearings, tools, electronic components, and machined parts. In addition, Wesco helps to manage the supply chain of aerospace companies. Wesco Aircraft focuses on just-in-time, or JIT, delivery of its goods to its customers in order to help minimize their inventory size. The majority of Wesco's sales are related to military planes.
For the full year 2010, Welco's total revenue was $656M. This was an increase from the 2009 figure of $613M. In 2010, the company reported a net income of $73.7M and $58M in 2009. 
The company's initial public offering of stock on the NYSE occurred on July 27, 2011. The company offered 21M shares each for $15. This was just below the initial price range of $15.50-$17.50. The deal raised a total of $315M. The lead underwriters were Barclays (BCS) and Morgan Stanley (MS).
In terms of net sales, Wesco receives more business for military planes than from commercial ones. In particular, sales for aircraft destined for the US Government make up a substantial portion of the company's revenue. If the U.S. Department of Defense cuts military spending as a whole, or ends a certain aircraft project, such as the F-35, the drop in demand for Wesco's parts would directly impact its business. Because the parts are often highly engineered, they are often not interchangeable across aircraft. As a result, the termination of a specific aircraft may have a direct impact on Welco.
