1. UnitedHealth Group (NYSE:UNH)
In the second quarter of 2025, Berkshire Hathaway acquired over 5 million shares of UnitedHealth Group, amounting to approximately $1.6 billion. This move was unexpected, given the insurer’s challenges, including a federal investigation over its handling of Medicare billing, as well as the resignation of the company’s CEO.
Despite these headwinds, the investment sent UnitedHealth’s stock price soaring almost 10% after-hours trading, highlighting Buffett’s confidence in the company’s long-term prospects.

2. T-Mobile (NASDAQ:TMUS)
Berkshire Hathaway closed out its entire position in T-Mobile US (TMUS) as of mid-2026, selling off a stake that had been worth around $1 billion. This move marked a complete exit from the telecommunications provider and reflected a strategic shift away from the sector.
The decision comes as Berkshire repositions its portfolio toward sectors like health care and industrials, signaling a renewed focus by Buffett on industries with greater perceived long-term stability.
3. Chevron (NYSE:CVX)
After reducing its stake in Chevron in previous years, Berkshire Hathaway has re-entered the energy sector with renewed vigor. The company acquired 3 million shares of Chevron this year.
This decision highlights the company’s confidence in the long-term value of energy investments, particularly in a world increasingly focused on energy security and sustainability.

4. Apple (NASDAQ:AAPL)
In the second quarter of 2025, Berkshire Hathaway trimmed its Apple stake by approximately 20 million shares, valued at around $9.2 billion.
This move may suggest Buffett is capturing gains while maintaining Apple’s status as one of the company’s core holdings. The move reflects a balanced approach, realizing returns without exiting a company that continues to generate substantial value.
5. Bank of America (NYSE:BAC)
Berkshire Hathaway also reduced its position in Bank of America, selling around 26 million shares, reducing the company’s holding in the bank to about 8%.
The pullback points to a calibrated shift away from heavy exposure in the banking sector. Still, Bank of America remains one of the company’s largest financial investments, which highlights Buffett’s continued confidence in its long-term prospects.
6. The impact of Buffett’s succession plan
With Warren Buffett announcing his retirement as CEO by the end of 2025, Berkshire Hathaway is undergoing a significant leadership transition. Greg Abel, one of the company’s longtime employees, will be the designated successor and is largely expected to maintain the company’s investment philosophy. However, with a new person may come new ideas; Abel may introduce new strategies to adapt to evolving market conditions, which could impact the company next year.
