Do stock buybacks always create value for investors?

There are two primary ways for businesses to return excess cash to shareholders. The more widely known method is paying dividends. The other, often underappreciated, is the stock buyback.

A stock buyback involves a company repurchasing its own shares from the open market, reducing the number of outstanding shares. This enhances the ownership stake of continuing shareholders.

For investors, it offers two benefits: one, the option to sell their shares; and two, the opportunity to benefit from a larger ownership stake and potentially improved share value over the long term.

Warren Buffett, the Oracle of Omaha, has long championed this tactic in his annual letters to Berkshire Hathaway shareholders. In this article, we take a closer look at stock buybacks, drawing primarily from Buffett’s 1980 annual letter for insight.

First, what is a stock buyback?

A stock buyback – also known as a share repurchase – is when a company buys back its own shares from the open market or directly from shareholders. There are a few ways companies conduct these buybacks:

• Open market purchases: The company quietly buys shares on the stock exchange.
• Tender offers: Shareholders are invited to sell back a portion (or all) of their holdings at a specified price.

In doing so, it reduces the total number of outstanding shares in circulation. You may ask what is used to make this hefty purchase.

And the answer is simple – at least for the right kind of buyback. And that is, it utilises cash, which then gets recorded as a reduction in assets.

It helps to look at the balance sheet equation to better understand how it impacts other aspects of the business:

Assets = Liabilities + Shareholders’ Equity

Since liabilities are unchanged, the shareholders’ equity falls. In the following section, we’ll explain the impact a buyback has on other metrics.

Impact of a stock buyback on the company and its stock

When done right, a stock buyback can strengthen the company’s financial profile. Here's how:

• With fewer shares (in the denominator), the same profit gets divided among a smaller number. As a result, EPS (Earnings per Share) increases.
• If we assume that the Price-to-earnings ratio will be steady, price will have to move to catch up with the new higher earnings per share resulting in stock appreciation.
• Since the company would use its reserves to buyback shares, consistent and higher buybacks would result in fall in reserves. Mathematically, a lower denominator would essentially boost the ratio and thus there would be an increase in ROE (return on equity.) Here’s a look at the formula of ROE:

Net Income / Average Shareholders' Equity

• Ownership concentration increases: Each share now represents a slightly larger claim on the company’s earnings and assets.

What did Warren Buffett say about stock buybacks?

Warren Buffett, perhaps the world’s most-followed investor, has laid down a simple yet powerful framework for evaluating buybacks:

1. Buybacks should be done only when the stock is undervalued.

In his 1980 letter to shareholders, Buffett wrote:

“One usage of retained earnings we often greet with special enthusiasm when practiced by companies in which we have an investment interest is repurchase of their own shares.  The reasoning is simple: if a fine business is selling in the market place for far less than intrinsic value, what more certain or more profitable utilisation of capital can there be than significant enlargement of the interests of all owners at that bargain price?”

The key here is the word “intrinsic.” It’s not about the market price but about what the business is truly worth. If the stock trades below that value, buying it back is like picking up a crumpled dollar bill for 80 cents. You wouldn’t hesitate, would you?

2. Buybacks are a form of capital allocation

In continuation of the previous quote:

“The competitive nature of corporate acquisition activity almost guarantees the payment of a full - frequently more than full price when a company buys the entire ownership of another enterprise.  But the auction nature of security markets often allows finely-run companies the opportunity to purchase portions of their own businesses at a price under 50% of that needed to acquire the same earning power through the negotiated acquisition of another enterprise.”

A CEO’s job is not just to run the business but also to allocate capital wisely. If reinvesting in operations or acquiring other companies won’t deliver a high return, and if the stock is undervalued, buying it back is the next best thing. After all, entire empires of regret are built on fast-paced, ill-timed, and thoughtless business acquisitions.

Buffett’s approach is rooted in opportunity cost. If a dollar used in a buyback generates more long-term value than a new project or dividend payout, it’s the smart move.

3. Buybacks at high valuations destroy value

While logic holds that companies would go in for buybacks only when their stock prices were well below their intrinsic values, that has not always been the case. Buffett says, “90 per cent of repurchases in the last 5 years were at silly prices and not in the interest of shareholders. Managers did it because everyone else was doing it. It’s interesting how many companies bought at two times current prices that aren’t [buying] now,” (Berkshire Annual Meeting 2009).

Why do companies buy back their shares?

There’s more than one reason why companies launch a stock buyback. Some are strategic; others, less noble.

Here are the main motivations:

• To return surplus cash: Instead of hoarding cash or expanding recklessly, companies return excess funds to shareholders.
• To boost metrics: EPS gets a short-term lift.
• To signal confidence: Management may believe the market is undervaluing the company.
• To appease shareholders: Activist investors sometimes push for buybacks to unlock value.

As investors, the “why” matters. A buyback driven by genuine undervaluation is a green flag. One done to please shareholders or prop up a sagging stock is cause for concern.

Are buybacks better than dividends?

This is a common debate in investing circles – and like most such debates, the answer is: it depends.

In essence, dividends are like receiving rent from a property, while buybacks are like increasing your ownership in the same property. Both can be rewarding – but the context matters.

When should buybacks worry you?

Not all buybacks are created equal. Some are outright red flags.

Here’s when to be cautious:

• Buybacks at inflated prices: This usually signals poor judgement or a desire to manage optics.
• Funded by debt: These are known as leveraged buybacks and can create financial risk – especially if interest rates rise or profits fall.
• Used to mask weak earnings: A rising EPS due to falling share count (not better profits) is financial window dressing.
• Designed to boost short-term stock prices: Especially common around executive bonus or stock option vesting periods.
• To transfer them to employees and management through stock options and stock rewards. 

It’s a case of intent vs outcome. If the buyback isn’t backed by sound fundamentals and long-term logic, it’s worth digging deeper.

So, are buybacks good or bad?

Like most tools, buybacks are neither inherently good nor bad. It depends on how, when, and why they’re used.

When done thoughtfully – below intrinsic value, with surplus cash, and with long-term vision – they can enhance shareholder value without the tax drag of dividends. But when done to boost optics or funded through debt, they can be more harmful than helpful.

The true measure lies in capital allocation discipline, and managers should be excellent capital allocators. Brilliant management that respects capital will treat buybacks with the same scrutiny as a new project or acquisition.

And for you, the investor? Always ask two questions:

• Is the buyback happening below intrinsic value?
• What’s the opportunity cost of that capital?

Because as Buffett says, “Price is what you pay. Value is what you get.” The next time you see a buyback announcement, don’t just cheer. Ask: is this value-enhancing – or just financial sleight of hand?

FAQs

Why do buybacks increase EPS even if profits remain the same?

Because EPS is calculated as profit divided by the number of outstanding shares. A lower denominator (fewer shares) means a higher EPS – even if the numerator (profit) stays constant. It’s financial arithmetic, not necessarily operational improvement.

Are stock buybacks taxable for investors?

Not directly. You’re only taxed if you sell your shares during a buyback and realise capital gains. If you hold your shares, there’s no tax implication. That’s why buybacks are often seen as more tax-efficient than dividends.

Can companies buy back shares anytime?

No. In India and most jurisdictions, companies must follow regulatory frameworks like SEBI's buyback regulations. They must disclose buyback intentions, price range, funding source, and more. There are also limits on how much capital can be used.

Should I sell my shares during a buyback?

Only if the buyback price offers an attractive premium to the market price and you believe the stock is fully valued or overvalued. Otherwise, long-term holders often benefit more by staying invested as their ownership increases.

How can I know if a stock buyback is value-accretive?

Ask two things:

• Is the buyback price below your estimate of intrinsic value?
• Is it funded via genuine free cash flow, not debt?

If the answer to both is yes, the buyback is likely adding value for continuing shareholders.
