UnitedHealth Group's shares rose notably in early August 2025 amid unconfirmed rumors that Warren Buffett's Berkshire Hathaway might take a stake in the company. The stock gained as much as 3% on the day these rumors circulated. More concretely, UnitedHealth reached a settlement with the U.S. Justice Department regarding its $3.3 billion acquisition of home health and hospice care provider Amedisys. The DOJ required UnitedHealth to divest 164 facilities across 19 states to address antitrust concerns, marking the largest outpatient healthcare divestiture. Additionally, Amedisys agreed to pay a $1.1 million penalty for false certification related to the deal. Despite the divestitures, the acquisition is expected to expand UnitedHealth's home and hospice care operations. Following the DOJ settlement, UnitedHealth's stock experienced some volatility but later showed strength, breaking above the $250 price level. Market commentary suggests that upcoming pharmaceutical tariffs could benefit UnitedHealth by addressing drug price gouging, potentially driving further stock gains.
