Dividends and buybacks

A company that earns more cash than it needs to run and grow the business has to do something with the surplus. It can sit on the cash, pay down debt, buy another company, or return the money to the people who own the business: the shareholders. That last option comes in exactly two flavors, and knowing how they differ is standard interview territory.

Dividends: a steady check to owners

A dividend is a cash payment the company sends to shareholders, quoted as an amount per share. Own 1,000 shares of a company that pays a $0.50 quarterly dividend and you receive $500 every three months, no matter what the stock price does. Most companies that pay one pay it on a regular schedule, and investors come to count on it.

That reliability is the whole personality of a dividend. It is sticky. Once a company sets a dividend, cutting it is read by the market as a distress signal, a confession that management no longer trusts the future enough to keep the check coming. So boards raise dividends slowly and defend them fiercely, because the punishment for cutting is a hammered stock price. Two ratios describe the size of a dividend. The dividend yield is the annual dividend divided by the share price, so a $2 dividend on a $50 stock yields 4%. The payout ratio is the dividend divided by net income, telling you how much of profit is going out the door versus staying in the business.

One more thing that trips people up: dividends are taxed. When the cash lands in a shareholder's account, they owe tax on it that year, whether they wanted the cash or not.

Buybacks: the company buys its own shares

A share repurchase, or buyback, is the other route. Instead of mailing cash to shareholders, the company goes into the market and buys back its own stock, then retires those shares. The shareholders who sell get cash; the ones who hold now own a slightly bigger slice of the same company, because there are fewer shares to go around.

The mechanical effect is on EPS. Net income is spread over fewer shares, so earnings per share rises even if the business earned exactly the same profit. Clean example. A company earns $100 million of net income with 100 million shares outstanding, so EPS is $1.00. It uses cash to buy back 10 million shares, leaving 90 million. Same $100 million of profit, now divided by 90 million shares, gives EPS of about $1.11. Nothing changed inside the business. The denominator just got smaller.

The other advantage is flexibility. A buyback carries none of the commitment a dividend does. A company can announce a repurchase program, buy aggressively for a quarter, then go quiet, and nobody reads a pause as a crisis the way a dividend cut would be read. Cash is returned only when management chooses. That flexibility is a big reason buybacks have overtaken dividends as the dominant way large US companies return cash.

Both drain the balance sheet the same way

Whichever route the company picks, the balance-sheet arithmetic is identical: cash on the asset side goes down, and shareholders' equity goes down by the same amount. A dividend reduces retained earnings; a buyback reduces equity through the shares retired. Either way the company is smaller by the cash it paid out.

This is the point that separates a real answer from a memorized one. Neither a dividend nor a buyback conjures value. They just move cash from the company's account to shareholders' accounts. A buyback adds an extra wrinkle: because the company is trading its cash for its own shares at a market price, the trade is good for continuing holders only when the stock is cheap relative to what it is truly worth, and bad when it is expensive.
