Charlesbank Capital Partners announced today that portfolio company Animal Health International Inc. (Nasdaq: AHII) has been purchased by Lextron, Inc. of Greeley, CO. Animal Health International (AHI) is one of the largest distributors of animal health products in the United States.

Founded in 1954, AHI purchases a wide array of pharmaceuticals, biologicals and other animal health products from more than 1,500 manufacturers.

Charlesbank acquired AHI in 2005 in conjunction with management and obtained a controlling interest in the equity.
