Dexcom Announces Leadership Transition as CEO Kevin Sayer Steps Down

Dexcom, a leading manufacturer of continuous glucose monitors (CGMs), has announced a significant leadership change. Kevin Sayer, who has served as CEO for the past decade, will step down from his role, with current Chief Operating Officer Jake Leach set to take the helm.

Leadership Transition Details

Kevin Sayer will officially relinquish his position as CEO on January 1, 2026. Jake Leach, who has been with Dexcom for 21 years, will assume the role of CEO and join the company's board of directors. Sayer will remain involved with the company, transitioning to the position of executive chairman of Dexcom's board of directors.

This leadership change comes as a result of the board's succession planning efforts. Sayer expressed confidence in Leach's ability to lead the company, stating that he is "the right leader to continue the company's growth."

Jake Leach's Background and Experience

Jake Leach brings a wealth of experience to his new role as CEO. His tenure at Dexcom spans more than two decades, during which he has held several key positions:

• Chief Technology Officer from 2018 to 2022
• Chief Operating Officer since late 2022
• Appointed as President in May 2025

Leach's extensive background in technology and operations positions him well to guide Dexcom through the evolving landscape of diabetes management technology.

Competitive Landscape in Glucose Monitoring

The announcement comes at a time of increasing competition in the continuous glucose monitoring sector. Dexcom faces challenges from other industry players, particularly Abbott, which has been expanding its integrations with automated insulin delivery systems. Additionally, the FDA has recently authorized longer-lasting implantable sensors, further intensifying the market dynamics.

In response to these competitive pressures, both Dexcom and Abbott made significant strides in 2024 by launching the first over-the-counter glucose sensors. This move has opened up new market opportunities and increased accessibility for consumers managing diabetes.

As Jake Leach prepares to take over as CEO, he will be tasked with navigating these competitive waters and maintaining Dexcom's position as a leader in diabetes technology innovation.
