Haren Bhakta walks through the shareholder letter Berkshire Hathaway (BRK/B) released with its earnings, and how the tone has changed with Greg Abel assuming the CEO-ship. Haren thinks Berkshire could look to improving the businesses they own, which Warren Buffett largely stayed away from, rather than focusing only on capital allocation. He notes that Abel specifically called out a subsidiary in the letter, signaling a possible culture break. Haren also thinks the board of directors may take more control and less companies will be interested in being acquired by Berkshire.
