Humana announced George Renaudin’s departure as president of its insurance segment. Amazon healthcare executive Aaron Martin will succeed him. Renaudin will retire next year after 29 years with the company. Martin, previously at Amazon, will join Humana as president of Medicare Advantage in January.

Humana reaffirmed its annual adjusted profit forecast of about $17 per share, causing shares to drop 2% to $260.68. Analysts are concerned about the lack of commentary on the 2026 open-enrollment period. Humana has been working to control healthcare costs by repricing plans and adjusting benefits.

Martin will take over as president of the insurance segment in the third quarter of next year, with John Barger succeeding him as president of Medicare Advantage. Renaudin will stay on as a strategic advisor through at least the end of 2026. The timing of the leadership transition is causing investor concern.
