AMERICAN VANGUARD REPORTS FOURTH QUARTER & FULL-YEAR 2008 RESULTS

Performance reflects continued increases in revenue, profit and shareholder equity driven by diverse market positions, international expansion, specialty product strength and conservative financial management

Newport Beach, CA – March 9, 2009 – American Vanguard Corporation (NYSE:AVD), today announced financial results for the fourth quarter and twelve month period ended December 31, 2008.

Fiscal 2008 Fourth Quarter Financial Highlights – versus Fiscal 2007 Fourth Quarter

• Net sales increased 3% to $71.1 million.

• Net income grew 5% to $ 7.9 million.

• Earnings per diluted share were $0.29, up from $0.28 in the prior year period.

Fiscal 2008 Twelve Month Financial Highlights – versus Fiscal 2007 Twelve Month performance

• Net sales increased 10% to a record $237.5 million.

• Net income rose 7% to a record $ 20.0 million.

• Earnings per diluted share were $0.73, compared with $0.68 earned during the prior year.

Eric Wintemute, President and CEO of American Vanguard, stated: “Our 2008 fourth quarter and full year performance has been driven by our participation in diverse domestic and international crop markets, the excellent performance of our non-crop specialty products segment and a continued emphasis on prudent operational and financial management. We continue to pursue a variety of initiatives to gain larger positions in key markets and geographic regions. We have maintained our traditionally high profit margins despite higher raw material costs by raising product prices where feasible and by continuing to focus on improving internal efficiencies and increasing capacity utilization at our domestic manufacturing facilities.”

Among the most important performance highlights of 2008:

• International sales continued to grow, led by significant gains in Canada, Mexico and Central America.

• Metam soil fumigant sales grew due to strong market demand, expanded coverage of the Southeast region and price increases needed to cover the higher cost of raw materials.

• New brand-name additions, such as Terraclor^® fungicides and Orthene^® insecticides, broadened our product offering and helped us further expand our participation in several key market segments.

• Non-crop specialty products improvement was aided by increased use of our mosquito adulticide Dibrom^®, following the strong hurricane activity that impacted several Gulf Coast states including Texas.

Mr. Wintemute concluded, “We are pleased that our quarterly and full year results continue to demonstrate the success of the American Vanguard business model. Our ability to acquire important product lines at reasonable prices and expand their usage is a proven contributor to our steady growth. We continue to seek attractive opportunities to acquire new product lines and expand our offerings. Our careful, step-wise expansion in international markets carries our expertise abroad without undue risk. Our outstanding domestic manufacturing capability affords excellent quality control, cost competitiveness and timely customer response. Given the many challenges of the current economic environment, we reiterate our intention to remain diligent in cost control, conservative in our investment outlays and collaborative with other industry participants to facilitate expansion of our established market position. Despite widespread economic uncertainty, we believe that the significant benefits we provide for enhancing agricultural productivity and improving crop quality will continue to be in demand and should fuel our growth potential in 2009 and beyond.”
