(Nov. 24) In a filing late yesterday with the Securities and Exchange Commission, Builders FirstSource announced that its SVP and CFO Charles Horn has resigned, effective Nov. 23, to take a position as a chief financial officer at an unnamed technology company.

Horn has been with Builders FirstSource since 1999. He leaves in the midst of an acrimonious battle that was launched when two of the company’s major shareholders proposed a recapitalization plan for the Dallas-based pro dealer.  

Horn will be replaced by Chad Crow, who previously served as the company’s VP and controller since May 2000. Crow joined Builders FirstSource in 1999 as an assistant controller. Prior to that, he served in a variety of accounting positions at Pier One Imports. Crow also spent four years at PriceWaterhouse.  

Listed ninth on the Home Channel News Top 350 Scoreboard this year, Builders FirstSource operated 55 lumberyards and 51 manufacturing plants in nine states. Sales in 2008 were $1.03 billion.
