Andrew Witty, UnitedHealth Group CEO, resigned from his position at the healthcare and wellbeing company on May 13, 2025. The company announced via a press statement on the same day that Witty, who had served the company for four years, would resign immediately for “personal reasons.”

It did not elaborate further on the reason for Witty's resignation. Witty's resignation from UnitedHealth Group comes after the company recorded its first earnings miss since the financial crisis of 2008.

UnitedHealthcare further revealed that Witty will be succeeded by Stephen Hemsley, chairman of the board and former CEO from 2006 to 2017. Witty was in charge following the Brian Thompson murder and the ensuing controversy regarding the health insurance industry and released an essay in the New York Times to address concerns about UnitedHealth Group.

Stephen Hemsley, in a statement, expressed his appreciation towards Witty and wished him the best in his future endeavors:

"We are grateful for Andrew’s stewardship of UnitedHealth Group, especially during some of the most challenging times any company has ever faced."

Hemsley added that he:

“Greatly valued Witty's leadership and compassion as chief executive and as a director and wish him and his family the best.”

Andrew Witty stated that he understood people’s frustration with the healthcare system

In Andrew Witty’s guest essay for the New York Times published on December 13, 2024, the former CEO of UnitedHealthcare Group acknowledged that the health system wasn’t working as well as expected:

“We know the health system does not work as well as it should, and we understand people’s frustrations with it. No one would design a system like the one we have. And no one did. It’s a patchwork built over decades.”

Witty added that there was a need for a more transparent approach to how the healthcare system operates:

“Together with employers, governments and others who pay for care, we need to improve how we explain what insurance covers and how decisions are made. Behind each decision lies a comprehensive and continually updated body of clinical evidence focused on achieving the best health outcomes and ensuring patient safety.”

In his New York Times guest essay, Witty emphasized that the slain CEO, Brian Thompson, advocated for quality healthcare. He also tried to correct the narrative that UnitedHealthcare mishandled insurance claims. He added that the company approves about 90% of its insurance claims.


Andrew Witty will continue to play a limited role as a senior adviser to new CEO Stephen Hemsley.
