Warren Buffett’s Berkshire Hathaway has made a significant investment in troubled insurer UnitedHealth, buying over 5 million shares worth approximately $1.6 billion. The stake makes UnitedHealth the 18th largest position in Berkshire’s portfolio, behind Amazon and Constellation Brands.
The insurer’s stock surged 6% in extended trading following the news. Shares were down nearly 50% for 2025 before Buffett’s filing. UnitedHealth is facing a Justice Department investigation into its Medicare billing practices and has been criticized for its high healthcare costs.
Buffett has been critical of the US healthcare system, calling it a “tapeworm” on the economy due to its high costs. He has also launched joint ventures to improve healthcare in the past but seen them shut down.
Berkshire also added stakes in steel manufacturer Nucor, outdoor advertising company Lamar Advertising, and security firm Allegion. The conglomerate trimmed its positions in Bank of America and Apple. Buffett is stepping down as CEO at the end of the year, handing over the reins to Greg Abel, but his legacy will live on through Berkshire’s equity portfolio.
