NEWPORT BEACH, Calif. -- American Vanguard Corporation (NYSE:AVD), today announced financial results for the fourth quarter and full year ended December 31, 2007.

Fourth Quarter Financial Highlights - versus fiscal 2006 fourth quarter

* Net sales increased 26% to $69.1 million.

* Operating income grew 20% to $12.8 million.

* Net income rose 40% to $7.6 million.

* Earnings per diluted share were $0.28, up from $0.20 in the comparable period of 2006.

Full Year Financial Highlights - versus the fiscal 2006 full year period

* Net sales increased 12% to $216.7 million.

* Operating income rose 23% to $36.0 million.

* Net income increased 21% to $18.7 million.

* Earnings per diluted share were $0.68, up from $0.57 for the 2006 full year period.

Eric Wintemute, President and CEO of American Vanguard, stated, "We are pleased to report continued sales and earnings growth for the fourth quarter and full year 2007. We are gaining traction on a number of key initiatives discussed during 2007, and the benefits of those successes will be increasingly evident in calendar 2008."

Among the major performance highlights:

* The Company's extremely effective herbicide, Impact[R] grew substantially in 2007 and should continue to gain market share based on superior performance and its increasing recognition as a preferred complement to the widespread use of Roundup[R] and other glyphosate products.

* Counter[R] and Aztec[R], our primary owned and licensed corn soil insecticides, both contributed significantly to quarterly and annual 2007 results and each should figure prominently in 2008, as corn growers are strongly encouraged to adhere more closely to refuge acre requirements and they begin to recognize the yield enhancement benefits of using these products in conjunction with their genetically modified seeds.

* Our business remains quite strong in potatoes, vegetables, fruits, and specialty turf & ornamental markets, niches in which we are particularly expert and where several new American Vanguard initiatives should further extend our penetration of these high-value segments.

* Sales of Bidrin[R], our cotton insecticide, were up during the fourth quarter although full year sales were down due to acreage shifts this past season from cotton to corn, a decline which may stabilize in 2008.

* In recent months, we acquired a PCNB fungicide product line from Chemtura and the Orthene[R] insecticide line from Valent, and both are already demonstrating their ability to contribute to future sales.

* Additionally, we expanded our high-quality domestic manufacturing capability by establishing a new presence in the Midwest (at Hannibal, Missouri) and the Pacific Northwest (at Marsing, Idaho) which will allow us to better serve these regional markets and permit optimization of production scheduling and logistics.

Mr. Wintemute concluded, "We are very optimistic about American Vanguard's position in the dynamic crop protection market. Our management team continues to demonstrate its ability to acquire, license and build upon niche product lines. The benefits to be gained by utilizing our portfolio of granular corn soil insecticide products and our proprietary application equipment are becoming self-evident with the release of university-validated yield enhancement performance data. We are optimistic that corn growers will increasingly choose to embrace a "dual" insect management approach by using our solution in concert with their genetically modified seed. We anticipate continued growth in our herbicide franchise, as Impact[R] receives expanded label endorsement from glyphosate suppliers for its ability to eliminate "tough-to-control" weeds. Importantly, we will continue to leverage our low-cost, high-quality U.S. manufacturing capabilities and will pursue international expansion with a variety of independent and collaborative efforts. We believe that we hold an enviable position in a number of important growth segments of the dynamically changing and rapidly growing agricultural industry."
