Here is what they have to say about Berkshire Hathaway Inc. (NYSE:BRK-B) in their investor letter:
“During the 2025 Berkshire Hathaway Inc. (NYSE:BRK-B) Annual Meeting, 94-year-old Warren Buffett announced the natural succession of leadership, with Vice Chairman Greg Abel assuming day-to-day responsibilities effective January 1, 2026. Buffett will retain his role as Chairman of the Board to ensure a seamless transition in governance and strategy.
The market’s predictable short-term reaction to this announcement was a sell-off, pushing prices down 10%. This is certainly temporary and creates a compelling entry point into one of the world’s greatest compounding machines. Berkshire enters the second half of 2025 with a record cash balance of approximately $350 billion. This is not idle cash; it is a fortress of dry powder, earning over 4%, providing extraordinary and unmatched capability to deploy capital into attractive assets during the next market downturn.
This contrarian advantage, combined with the proven capital-allocation discipline of its culture, is what has driven decades of returns. Under the operational leadership of Abel and the continued strategic oversight of Buffett, we are confident that Berkshire Hathaway is positioned to compound in value during the years ahead.”
