American Vanguard to List on the New York Stock Exchange.

NEWPORT BEACH, Calif. -- American Vanguard Corporation (AMEX: AVD) today announced that it will list its common stock on the New York Stock Exchange. Accordingly, the Company has applied to withdraw its securities from listing on the American Stock Exchange. Trading on the NYSE is expected to commence on Wednesday, March 8, 2006, subject to the Company's selection of a specialist and the completion of the proper securities filings. The Company's ticker symbol will remain 'AVD.' Until the move, American Vanguard's common stock will continue trading on the American Stock Exchange.

Eric Wintemute, President and CEO of American Vanguard, stated, "Listing on the NYSE is a significant and exciting development for the Company. In considering the move, we were impressed with the new hybrid platform that the NYSE is currently implementing, which will permit both electronic and specialist-assisted trading. We believe the platform will appeal to a broad range of investors and should dampen intraday price volatility. The new listing should also enhance the Company's exposure and the trading liquidity of our stock. This milestone event is a product of our continued commitment to maximizing shareholder value."

Mr. Wintemute continued, "We thank the AMEX for their support and service over the past eight years. During that time, American Vanguard has achieved tremendous growth in sales, earnings and market cap, and the AMEX has played an important role. Having now surpassed $500 million in market cap, from about $16 million when we joined the AMEX, we think the time is right for a move. We look forward to establishing a balance between specialist-assisted trading, which served the Company well on the AMEX, and electronic trading, which provides increased flexibility to our shareholders."

The Company expects the move to the New York Stock Exchange to be seamless for American Vanguard shareholders. Shareholders that hold a stock certificate do not need to replace the certificate. At such time as shareholders might sell the shares represented on the certificate, the transfer agent will automatically recognize the shares as American Vanguard stock on the New York Stock Exchange.
