American Vanguard Announces Marsing Facility Acquisition.

NEWPORT BEACH, Calif. -- American Vanguard Corporation (NYSE:AVD) today announced that it has acquired an established production facility in Marsing, Idaho from Bayer CropScience LP.

This self-contained production facility has the capability to formulate and package a number of active ingredients into finished "flowable" products that are used in a wide variety of crop protection applications. Formerly owned by Gustafson and Crompton Corporation, this operation has a lengthy history of manufacturing many important ingredients that are employed in various seed treatment formulations.

Eric Wintemute, President & CEO of American Vanguard commented, "This production capability will allow AMVAC to expand the range of its offering to customers interested in "on-seed" coating protection. When combined with our extensive line of soil treatment and plant protection products, our customers will now be able to choose from a wider portfolio of pest defense measures, manufactured in AMVAC's highly reliable, domestic production facilities."

The purchase agreement calls for American Vanguard to supply Bayer CropScience for several years with some of the Bayer products currently formulated at the site, facilitating both a seamless transfer of the site's operations to American Vanguard and the transition of that production by Bayer to its own operations. Other specific terms of the transaction were not disclosed.

Mr. Wintemute concluded, "This acquisition further strengthens our recent emphasis on establishing a broad-based, high-quality domestic manufacturing capability to serve the needs of growers in every region of the North American market. With our Metam Sodium & Potassium expansion in Axis, Alabama to serve the Southeast U.S., and our Hannibal, Missouri facility to serve the central "grain belt", we now add a well-positioned location to facilitate the demands of the Northwestern U.S. and Western Canadian markets."
