Accelerated Share Repurchase Programs

A company that wants to buy back $500 million of its own stock usually does it gradually, over months, to avoid moving the price. An accelerated share repurchase (ASR) skips the wait: the company pays an investment bank $500 million upfront, and the bank immediately delivers most of the shares that day, borrowing them from its stock-lending desk. The bank then spends the next several weeks or months buying real shares in the open market to cover what it borrowed, and true-up payments settle the difference between the upfront price and the market's average price over that period.

How the mechanics play out. Say a company pays $500 million and the stock is trading at $100, so it receives roughly 4.75 million shares immediately (a discount built into the initial delivery to protect the bank). Over the next three months, the bank buys shares in the market to unwind its borrow. If the average price it actually paid comes in at $95, the company effectively overpaid relative to that average, and the bank delivers it additional shares (or cash) to true up the difference; if the average price comes in above $100, the company owes the bank more.

Companies favor ASRs around earnings announcements or index-weight changes because the share count drops right away, immediately boosting reported earnings per share — a plain $-per-share metric investors watch closely — even though the true cost of the buyback isn't locked in until the program completes.

An ASR trades price certainty for immediacy: the company knows its cash outlay on day one but not its final cost per share, which floats with the stock's average price during the unwind period.
