Berkshire Hathaway has reached an unprecedented cash position of nearly $400 billion, solidifying its status as the holder of the largest corporate cash reserve in American history. This massive liquidity allows the company to potentially acquire up to 497 S&P 500 companies outright. Amid this financial strength, Berkshire reported an 18% increase in Q1 operating earnings to $11.3 billion and appointed Greg Abel as Warren Buffett's successor, tasked with upholding the company's long-term principles.
