Why companies buy back their own shares

A company buying its own shares sounds like a snake eating its tail. It isn’t, quite. But it’s also not the gift the press release makes it sound like. Let’s take it apart.

What actually happens

The company takes cash it has (or borrows) and buys its own shares, either on the market over time or through a formal offer to shareholders. Those shares are usually cancelled. The business is the same size. There are just fewer slices of it.

If a company is split into 100 slices and buys back 10, each of the remaining 90 now owns a bit more of the same business, the same profits and the same future dividends.

Why the market often cheers

It’s cash going back to owners. Shareholders who want out get a buyer. Shareholders who stay end up owning a bigger share. Either way, cash leaves the company and lands with the people who own it.

It’s a signal. A board buying shares is, in theory, saying “we think our own stock is cheap”. Management knows more about the business than anyone outside it, so investors pay attention.

Earnings per share go up. Same profit divided by fewer shares equals a higher number per share. That one’s arithmetic, not magic, and we’ll come back to it.

It’s flexible. Raise a dividend and investors expect it every year forever. A buyback can be switched off when times get tough without the same uproar.

Why I read the fine print anyway

A buyback is only as smart as the price you pay.

Price matters. Buying back shares when they’re cheap is a great deal for the owners who stay. Buying them back at a record high, because the cash was burning a hole in the CFO’s pocket, transfers value to the people who sold. Plenty of companies buy most aggressively at the top and stop when the shares are cheap, which is exactly backwards.

Earnings per share can flatter. If executive bonuses are tied to EPS, a buyback can hit the target without the business improving at all. The profit didn’t grow, the denominator shrank. Always check whether total profit is growing, not just profit per share.

Debt-funded buybacks need a hard look. Borrowing to buy back shares can make sense when debt is cheap and the business is steady. It also leaves less room when a bad year arrives.

Some buybacks are just mopping up. Many companies pay executives and staff in shares, which creates new shares every year. A chunk of the buyback simply soaks those up. The share count barely moves, and the “return to shareholders” is really a payroll cost by another name.

The tax angle, briefly

Since 2023, US-listed companies pay a 1% excise tax on the value of shares they repurchase. In Australia, off-market buybacks have their own tax treatment that can differ a lot from selling on market. Tax depends on your own situation, which is precisely the kind of thing I don’t answer, so talk to a registered tax agent.

So, good news or not?

Ask three questions:

1. Were the shares cheap when they bought them?
2. Is it funded from genuine spare cash, or from debt the business can’t easily carry?
3. Did the share count actually fall, or did the buyback just cancel out shares handed to management?

If the answers are yes, spare cash and yes, it’s probably a sensible use of the money. If not, it’s makeup on a business that isn’t growing.
