He also has overseen our corporate finance areas since 2020, including financial reporting, investor relations, tax, treasury, and financial planning and analysis. IDEXX has significant opportunities to continue expanding our reach, driving innovation, delivering for our customers and executing on business development initiatives, while creating long-term value for our shareholders and other stakeholders.

“I am honored to be named IDEXX’s CFO-elect, and look forward to building on IDEXX’s momentum,” said Mr. Emerson. “With a strong financial foundation and clear strategic drivers, the Company is well-positioned to continue growing revenue, increasing profitability and delivering long-term value. I am excited to lead the finance organization and look forward to working closely with Brian as I transition into the CFO role.”

Mr. Mazelsky added, “On behalf of the Board and management team, I thank Brian for his leadership, guidance and partnership. Brian has been a true asset to IDEXX for more than two decades, having first served as a Director on our Board before stepping into the CFO role ten years ago. With Brian’s help and oversight, we have delivered outstanding financial results, expanded our global footprint and executed a disciplined capital allocation strategy. IDEXX is in a position of strength today, poised for continued success, and we wish Brian the very best in his next chapter.”

“It has been the highlight of my career to work alongside the talented team at IDEXX, and I am proud of all we have accomplished together,” said Mr. McKeon. “Since joining IDEXX first as a Director in 2003, and then as CFO in 2014, I have been honored to play a part in the growth of IDEXX and development of solutions that are enhancing the health and well-being of pets, people and livestock. IDEXX is fortunate to have a strong and talented leader like Andrew as the Company’s next CFO. I look forward to watching the Company’s continued success for many years to come.”
