A M E R I CA N VA N G UA R D C O R P O R AT I O N THE FACES OF AMVAC 2011 ANNUAl REPORT Message from the Chairman Dear Shareholders, For American Vanguard, 2011 was a year of exceptional growth, record financial performance and continuing organizational development. As we asserted last year, AMVAC was prepared to take advantage of current opportunities and was well-positioned to pursue a world of future possibilities. In 2011, the efforts of our domestic and international sales, marketing, business development and customer-service personnel contributed to a 34% increase in revenues. Our manufacturing, logistics and regulatory teams did an outstanding job of getting our products to market proficiently. Our finance, information technology and human resource functions handled the substantial administrative workload of a growing enterprise. Through the efforts of these many “Faces of AMVAC,” we achieved a doubling of net income, a 12% increase in stockholders’ equity and a strong balance sheet that contained $35 million in cash at year-end. During 2011, we successfully integrated into our portfolio the products that we acquired in late 2010. We experienced solid market demand for most of our product lines and in most of the crops that we serve. We improved the capacity utilization of our manufacturing facilities, prevailed in our efforts to return the fungicide PCNB to the U.S. market, and attracted additional highly skilled and experienced personnel to join the AMVAC team. A significant contributor to our recent success and a major lever for expanding our business in the future lies in the U.S. corn market. Global demand for corn has been very strong, causing corn commodity prices to remain relatively high, which encourages farmers to seek maximum harvest output by purchasing the type of yield-enhancing inputs that AMVAC provides. To capitalize on this substantial opportunity, we are promoting our message of Yield Enhancement Solutions (YES) involving our Impact® herbicide and our extensive offering of proven granular-soil insecticides with related proprietary closed- delivery equipment systems. Customer-focused sales service is an essential part of our successful growth. From left to right are Glen Anderson, Monique Patino, Rebecca Montano, Dorinda Van Beek, Veronica Plascencia. Last summer we were able to arrange a co-marketing agreement with Monsanto to encourage growers to use our Impact® post-emergent herbicide to assist Monsanto’s Roundup® general-purpose herbicide to cope with the increasing challenge of glyphosate resistant weeds. We have seen a renewed demand for the use of traditional corn-soil insecticides in conjunction with genetic trait seeds for a yield-enhancing combination of technologies that we have promoted for several years as “The Best of Both Worlds.” Increasingly, the marketplace is embracing the wisdom of this philosophy: using all available tools to combat the infestation that reduces yield and inhibits our collective ability to provide the food, fiber and biofuels that our expanding global human population requires. American Vanguard finds itself in a great place—within a great industry. In a world that must double farm production in the next two decades, and in an industry that must adapt to the ever-changing challenges of Mother Nature, American Vanguard has positioned itself to be a major player. We had the foresight to assemble and defend a portfolio of traditional chemistries that now appears to be very much in demand. We have dedicated ourselves to high-quality, environmentally compliant manufacturing, responsible product stewardship and the advocacy of modern Integrated Pest Management. We are continually creating a corporate culture that is focused on innovation, entrepreneurial initiative and opportunistic growth. We have great confidence in our people and our future prospects. We hope that you share that confidence and benefit from our continued success. Eric G.
