• EBITDA up 37% to $42.0 million in 2021, as compared to $30.5 million in 2020

Eric Wintemute, Chairman and CEO of American Vanguard, commented: “We achieved strong third quarter results and continued performance improvement over the first three quarters of 2021. Strong crop commodity prices, favorable weather and pest pressure have fueled significant growth of our US crop sales, particularly in the Midwest and the South. Mosquito mitigation driven by tropical storm activity, commercial pest control, lawn and garden demand and our consumer pest collaboration with Proctor & Gamble’s Zevo^® brand have grown this year’s US Non-Crop business. Internationally, our success in Central America, Brazil, Australia and elsewhere has resulted in expanded revenues and enhanced profitability.”

Mr. Wintemute continued, “Our year-to-date performance exceeds our prior guidance with net sales increasing at a 25% rate and a more significant gain of 87% in net income and earnings per share. We have achieved these results in spite of pandemic conditions and delays in the global supply chain. Through the balance of the year, we expect strong sales, efficient manufacturing performance and earnings in excess of those posted last year. From a balance sheet perspective, we are on track with both inventory management and debt reduction as we head towards the end of the year.”

¹  Earnings before interest, taxes, depreciation, and amortization. EBITDA is not a financial measure calculated and presented in accordance with U.S. generally accepted accounting principles (GAAP) and should not be considered as an alternative to net income, operating income or any other financial measure so calculated and presented, nor as an alternative to cash flow from operating activities as a measure of liquidity. The items excluded from EBITDA are detailed in the reconciliation attached to this news release. Other companies (including the Company’s competitors) may define EBITDA differently.

Mr. Wintemute concluded, “We continue to pursue strategic growth initiatives in technology development, with particular emphasis on Green Solutions and Precision Application technologies. We look forward to providing details on our overall performance, industry outlook and innovation initiatives in our upcoming quarterly conference call.”
