Analysis · BRKB · Finance
Warren Buffett converted 8,000 Class A shares into 12 million Class B shares and immediately donated 12 million Class B shares — worth approximately $5.9 billion at current prices — to four foundations, including the Susan Thompson Buffett Foundation. This is a significant annual philanthropic event that reduces his economic interest to 13.2% while maintaining 29.7% voting control. The conversion and donation are part of his long-standing pledge to give away his fortune, but the sheer dollar magnitude makes this a notable event for Berkshire shareholders, as it incrementally shifts the ownership structure without altering his voting grip.
