UnitedHealth Group has announced the resignation of CEO Andrew Witty for personal reasons, coinciding with the company's struggles with higher-than-expected medical costs. Alongside Witty's departure, the health insurer suspended its 2025 financial outlook, marking a significant shift following its first quarterly earnings miss in over a decade, according to Le Monde, India Times, and CBS News.

Stephen Hemsley, who previously served as CEO from 2006 to 2017, will step back into the role immediately. Witty will continue with the company as a senior adviser during the transition period. The company’s challenges have been compounded by the shocking murder of former CEO Brian Thompson, which occurred in December and resulted in a marked decline in stock value, dropping 38% since the incident.

Hemsley expressed his disappointment over recent performance setbacks, acknowledging that many issues within the company’s control have contributed to the current turmoil. He emphasized a commitment to address these challenges with "humility, rigor and urgency." Following Witty's tenure, which saw substantial growth, including a 55% revenue increase, the company now faces investor anxiety and scrutiny due to rising operational costs and the ongoing murder investigation of Thompson, which has attracted widespread media attention, according to India Times and CBS News.
