American Vanguard Named to the 2005 Fortune Small Business List of America's 100 Fastest Growing Small Companies.

NEWPORT BEACH, Calif. -- American Vanguard Corporation (AMEX:AVD) today announced that it has been ranked #40 on the FSB 100 list of America's Fastest-Growing Small Companies, which represented the Company's third consecutive year on the list. The list is currently available at www.fsb.com and it will appear in the July/August issue of the magazine available on newsstands July 4th.

To compile the list, FORTUNE Small Business asked financial research firm Zacks to screen for public companies with annual revenue of less than $200 million and a stock price of more than $1. Within that group, companies were ranked based on the past three years' earnings growth, revenue growth, and stock performance. Real estate firms and banks, which had begun to override the list in recent years, were not considered for the list this year.

Eric Wintemute, President and CEO of American Vanguard, stated, "We are very honored to be included on FORTUNE Small Business' list for the third year in a row. This comes on the heels of our inclusion in BusinessWeek's Hot Growth Companies list last month. This recognition of American Vanguard's success and growth is certainly gratifying."
