AMERICAN VANGUARD CORP

Item 1A. Risk Factors

The Company continually re-assesses the business risks, and as part of that process detailed a range of risk factors in the disclosures in American Vanguard’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025, filed on March 16, 2026. There has been no material changes in our risk factors as of March 31, 2026, except as follows:

The war between the US and Iran coupled with instability among other nations within the Middle East may have an adverse effect upon the agricultural economy in general and the Company’s financial performance in particular. Military activity in and near Iran and the consequent blockade of the Strait of Hormuz are interfering with international shipping lanes for oil, fertilizer and other products which, in turn, are increasing grower costs. In addition, these activities could lead to counterterrorism and/or counterattacks that could put US persons and assets at risk. These factors are likely to further constrain grower liquidity and profitability, to affect growers’ procurement practices and lead to a reduction in demand for the Company’s products. There is no guarantee that the war will end any time soon or that the terms of its cessation will restore shipping lanes to pre-blockade status. In short, these factors could have a material adverse impact on the Company’s operations and/or financial performance.
