ABC Supply, Beloit, Wis., has been the No. 1 dealer on the ProSales 100 list since 2011. The company rose to the top because of its acquisition of Bradco in 2010. That deal increased ABC Supply's pro sales from $2.6 billion in 2009 to $4 billion in 2010. The company then saw another jump in growth with its acquisition of Norandex in 2015. That deal added over 100 locations to ABC Supply.

Now, the company will have a second growth spurt in 12 months. Earlier this week, ABC Supply announced it will acquire L&W Supply from USG. L&W Supply is No. 9 on the 2016 ProSales 100, has 142 locations, and reached $1.4 billion in pro sales in 2015. ABC Supply reported $5.8 billion in pro sales in 2015. Combined, L&W Supply and ABC Supply achieved $7.2 billion in pro sales for 2015, which hints at the potential growth the acquisition could bring to ABC Supply.
