IDEXX Laboratories, Inc. has appointed Michael Erickson, PhD, as its new President and Chief Executive Officer, effective May 12, 2026. Erickson, who joined the company in 2011, has led the Global Point‑of‑Care Diagnostics and Telemedicine businesses and will take over day‑to‑day operations and strategic direction. Current CEO Jonathan Mazelsky will transition to Executive Chair of the Board, remaining in a senior advisory role until the end of 2027.
The change comes after a period of robust growth for IDEXX. Over the past year the company has delivered a 71.5% return to investors, driven by expanding demand for veterinary diagnostics and software solutions. Management has also pursued an aggressive share‑buyback program, underscoring confidence in the business and providing additional value to shareholders.
Independent Non‑Executive Board Chair Lawrence D. Kingsley said, “Mike has a deep understanding of the business and is uniquely well‑suited to lead the Company forward and build on its strong momentum at the forefront of the veterinary diagnostics industry.” Mazelsky added, “I am confident the Company is well‑positioned for sustained growth and success, and I look forward to supporting the transition as Executive Chair.” Erickson noted, “IDEXX is at the center of the veterinary ecosystem, and we have an immense opportunity to advance medical care through our 40‑year history of innovation.”
The succession plan reflects IDEXX’s focus on continuity and incremental innovation. Erickson’s background in diagnostics, software, and telemedicine aligns with the company’s strategy to expand its digital platform and global reach. By keeping Mazelsky on the board, IDEXX signals a smooth transition that preserves institutional knowledge while positioning the company to accelerate growth in high‑margin segments.
Investors have reacted positively to the announcement, citing the stability of the leadership transition and the company’s strong financial footing. The decision to appoint an internal successor and retain the outgoing CEO in an advisory capacity is viewed as a low‑risk move that preserves the momentum built over the past years. Analysts have highlighted the company’s continued investment in AI and telemedicine as key drivers of future growth.
For long‑term investors, the leadership change reinforces IDEXX’s trajectory of disciplined cost management, expanding product mix, and a growing global customer base. The company’s track record of share buybacks and solid earnings growth suggests that the new CEO will be able to sustain profitability while pursuing strategic investments in diagnostics and digital health.
