"This warrant exercise reflects American Vanguard's firm belief in the continued growth and commercial success of TyraTech. TyraTech's unique technological innovations drive the introduction of safe and effective consumer products for pest control and human health protection. The recent commercialisation of Vamousse® head lice treatments in the United States and United Kingdom and the introduction of Guardian®, a highly-effective, non-DEET mosquito repellent are prime examples of this technical leadership. Expected strong future demand for these human health care products reinforces the attractiveness of our ownership position in TyraTech."

Alan Reade Non-Executive Chairman of TyraTech commented:

"American Vanguard is a highly valued shareholder and business partner. As a shareholder they understand the value proposition that the TyraTech technology platform offers and as a business partner they assist the company in identifying, developing and exploiting opportunities in crop protection and other professional insect control markets via Envance Technologies LLC, our joint venture with AMVAC. In addition to this TyraTech also benefits from the experience and business knowledge Eric Wintermute brings to the Board."
