ASTEC INDUSTRIES, INC. ACQUIRES PETERSON, INC., MANUFACTURER OF ENVIRONMENTAL, WOOD, CONSTRUCTION DEBRIS AND WASTE PRODUCT PROCESSING EQUIPMENT

CHATTANOOGA, Tennessee, (July 31, 2007).  Astec Industries, Inc. (NASDAQ: ASTE) finalized today the previously announced purchase of Peterson, Inc. (“Peterson”) located in Eugene, Oregon.

The final purchase price including closing adjustments was $21,100,000 with the possibility of additional payments of up to $3,000,000 in total based on Peterson’s 2008 and 2009 financial results.  The Company also paid off approximately $7,000,000 of outstanding Peterson debt.  Under a separate contract, the Company agreed to purchase at a future date all of the real estate and improvements used by Peterson for approximately $7,000,000.

Peterson is a leading manufacturer of whole-tree pulpwood chippers, horizontal grinders and blower trucks.  Founded in 1961 as Wilbur Peterson & Sons, a heavy construction company, the company expanded into manufacturing in 1982 to develop equipment to suit their land clearing and construction needs. By 1990 Peterson had developed its first wood recycling machine and since that time continuous development has led to the existing product line. The company will continue to operate from its Eugene headquarters under the name Peterson Pacific Corp.  Peterson’s average sales per year for the last three fiscal years (ending on June 30, 2007) were approximately $66,000,000.
