[LEXINGTON, Ky.] — E. Michael Castle II has been appointed chief operations and financial officer at Alltech.

Castle has been with Alltech for 19 years, most recently serving as chief operating officer and CEO of the Alltech Feed Division. He has deep experience in the business globally, having also served as chief administrative and legal officer, among other roles.

Castle began his career at Alltech as an engineering intern. He went on to earn a Juris Doctor from Washington University St. Louis School of Law and then returned to Alltech.

"Having worked with Alltech for almost two decades, Mike has Alltech DNA through and through. He worked closely with our leadership team and my father on many of the most important deals in our history. Since the passing of Dr. Pearse Lyons in 2018, Mike and I have worked hand in glove to lead the business,” said Dr. Mark Lyons, president and CEO of Alltech. “In all his endeavors, Mike has demonstrated unparalleled dedication, exemplary leadership and a passion for excellence. He is an invaluable asset to Alltech – and a trusted friend and colleague to me. There is no one better prepared — and no one I'd rather work alongside — to lead Alltech into the future.”

Castle is supported in leadership of Alltech’s financial strategy by:

  • May Xu, deputy CFO, audit and reporting
  • Flora Djojo, chief tax officer
  • AnaLucia Medrano, who has been promoted to director of financial planning and analysis (FP&A). Medrano most recently served as finance director of Alltech Crop Science.
  • Hemant Gandhi, vice president of finance, global treasury

Alric Blake, former CFO and CEO of Alltech who served as interim CFO over 2023 Q3-Q4, will remain a senior advisor to the business.

“Alltech has an exciting future built on its strong foundation of helping farmers, ranchers and producers nourish the world and nurture the planet,” said Castle. “I am pleased to continue working alongside Dr. Mark Lyons to help Alltech capitalize on opportunities to provide solutions that improve the health of animals and the soil, maximize the value of feed, increase on-farm efficiency and help lower environmental impact.”
