AMERICAN VANGUARD REPORTS THIRD QUARTER RESULTS

Net Income Rises 28% on 11% Sales Increase

Newport Beach, CA – November 7, 2007 – American Vanguard Corporation (NYSE:AVD), today announced financial results for the third quarter and nine months ended September 30, 2007.

Third Quarter Financial Highlights – versus fiscal 2006 third quarter

• Net sales increased 11% to $56.6 million.

• Operating income grew 32% to $10.0 million.

• Net income was $5.4 million, up 28%.

• Earnings per diluted share were $0.20, up from $0.16 in the comparable period of 2006.

Nine-Month Financial Highlights – versus fiscal 2006 nine-month period

• Net sales increased 6% to $147.6 million.

• Operating income rose 25% to $23.2 million.

• Net income increased 11% to $11.2 million.

• Earnings per diluted share were $0.41, up from $0.37 in the 2006 nine-month period.

Eric Wintemute, President and CEO of American Vanguard, stated, “We are pleased to report continued sales and earnings growth for the third quarter. Impact^® sales again grew substantially, as this extremely effective corn herbicide continues to gain share based on its superior performance and value. Counter^®, our newest systemic insecticide / nematicide, and Thimet^®, our branded phorate insecticide, both contributed significantly to quarterly results and each remains on-track for a strong finish in 2007. Sales of Bidrin^®, our cotton insecticide, were up during the third quarter as pest pressure increased, however, year-to-date sales remain down due to the acreage shift this season from cotton to corn. Sales of Dibrom^®, our mosquito adulticide, suffered during the quarter, as drought in the southeast U.S. resulted in significantly reduced demand.”

Mr. Wintemute concluded, “We anticipate further top and bottom-line growth during the balance of 2007, driven by sales of our corn soil insecticide and fumigant products. Additionally, we continue to be very optimistic about American Vanguard’s long-term position in the dynamic crop protection market. Among the many reasons:

• Our management team’s proven ability to acquire, license and build upon niche product lines.

• The benefits gained by utilizing our portfolio of granular insecticide products and our proprietary closed delivery systems.

• Continued growth in the corn herbicide market, as Impact^® demonstrates its ability on “tough-to-control” weeds.

• American Vanguard’s ability to leverage low-cost, high-quality U.S. manufacturing capabilities.

• The Company’s potential for international growth in coming years, spearheaded by our own efforts, as well as possible collaboration with other companies to incrementally expand our global sales presence.”
