Additionally, American Vanguard reported that Hurricanes Katrina and Rita did not have a material impact on its business operations. The Company experienced a minor disruption in its manufacturing and supply. American Vanguard’s Axis, AL facility, which was closed for a total of 14 days, sustained minor damage from Hurricane Katrina.

Eric Wintemute, President and CEO of American Vanguard, commented, “We are pleased to report that we did not experience a significant disruption in our business operations from either of the hurricanes. Accordingly, we do not anticipate any material storm-related impact on our financial results for the third or fourth quarters of 2005. With regard to our mosquito adulticide, Dibrom^®, we are gratified that once again it is proving to be a valuable tool in helping stem the spread of diseases. Although we do not anticipate its sales to reach the levels generated from last year’s hurricane season, the sales will have an overall positive financial effect.”

The Company expresses its sympathy and encouragement to those who have suffered from the devastation brought on by the recent hurricanes. In response, American Vanguard is matching dollar for dollar, the contributions made by its employees to hurricane relief assistance groups with a donation to support the efforts of The Red Cross.
