Share repurchases can be the smartest thing a company ever does — or the dumbest. - Warren Buffett, 1999 Meeting

Let’s keep it simple.

A company has 100 million shares and earns $1B per year. EPS is $10. If it trades at a P/E of 10, the stock is $100.

Now assume net income stays flat at $1B, but over the next decade the company retires 90% of its shares. Shares fall from 100M to 10M. EPS jumps from $10 to $100. If the P/E stays the same, the stock goes from $100 to $1,000.

Same business. Same earnings. Same multiple. The only change is fewer shares. That’s the entire buyback game. That’s why it’s beautiful.
