FOR IMMEDIATE RELEASE

AMERICAN VANGUARD ESTABLISHES QUARTERLY DIVIDEND POLICY AND EQUITY REPURCHASE PLAN

Newport Beach, CA – June 10, 2013 – American Vanguard Corp. (NYSE:AVD) today announced that its Board of Directors has established a quarterly dividend payment policy, replacing its traditional semi-annual cash dividend payment practice. Accordingly, the Board declared a $0.05 cash dividend payment to be distributed on July 19, 2013 to shareholders of record as of July 5, 2013. Additionally, the Board of Directors voted to authorize the Company to repurchase its outstanding common shares.

Eric Wintemute, Chairman and CEO of American Vanguard, stated, “We are pleased to declare this dividend, which continues our 20-year history of providing such returns to our shareholders. This new quarterly payment approach will allow our shareholders to realize more immediate benefits from the continuing expansion and financial success of our Company. We also want to maintain a disciplined approach to our equity base. Since performance-based incentives can include restricted stock and stock option grants, we have instituted a share repurchase program with the intent of maintaining the current level of outstanding shares. This dividend policy and disciplined equity plan reflect our belief that increasing shareholder value is of prime importance to Company management and its Board of Directors. These steps also indicate the confidence that management and the Board of Directors have in the Company’s future. We appreciate our investors’ continued support as we pursue profitable growth in the crop protection and public health markets worldwide.”
