Buffett bet big on United Health in 2Q25 -- now Berkshire Hathaway could be down billions.
A 13F filing from Berkshire Hathaway unveiled the purchase of 5,039,564 UNH shares by the conglomerate in the second quarter, a position that represented one of the largest new buys from the company, then led by Buffett.
The purchase of UnitedHealth shares in the second quarter may have represented an example of Buffett seeing value. The murder of a senior executive, antitrust investigations, and a cyberattack saw shares of the health insurance company trade lower in the early months of 2025.
It is unknown exactly when Berkshire Hathaway bought its UnitedHealth shares, a purchase made in the second quarter and marking the first time the conglomerate had owned shares of the health insurance company in several years.
UnitedHealth stock hit a second-quarter low of $248.88 on May 15 and had a second-quarter high of $606.36.
This means that Berkshire Hathaway bought UNH stock at a price between $248.88 and $606.36 per share. Given Buffett’s often value-oriented approach, it’s more likely shares were bought on the lower side, closer to $248.88.
Based on the 5,039,564 UNH shares purchased by Berkshire Hathaway, the purchase amounts would have been in a range of $1,254,246,688.32 to $3,055,790,027.04 based on the lowest and highest prices for the shares in the second quarter.
With shares trading at $283.80 on Tuesday after quarterly financial results disappointed investors, Berkshire's stake is now worth $1,430,228,263.20.
