Stock Buybacks: Benefits of Share Repurchases

There are several ways in which a company can return wealth to its shareholders. Although stock price appreciation and dividends are the two most common ways, there are other ways for companies to share their wealth with investors.

In this article, we will look at one of those overlooked methods: share buybacks or repurchases. We'll go through the mechanics of a share buyback and what it means for investors.

Key Takeaways

  • A stock buyback occurs when a company buys back its shares from the marketplace.
  • The effect of a buyback is to reduce the number of outstanding shares on the market, which increases the ownership stake of the stakeholders.
  • A company may buy back shares because it believes the market has discounted its shares too steeply, to invest in itself, or to improve its financial ratios.
  • Share buybacks can help companies reduce the dilution caused by employee stock option plans.
  • Share buybacks after Dec. 31, 2022, that exceed $1 million are subject to a 1% excise tax.

How Does a "Buyback" Work?

What Is a Stock Buyback? 

A stock buyback occurs when a company buys back its shares from the marketplace with its accumulated cash. Also known as a share repurchase, a stock buyback allows a company to re-invest in itself. The repurchased shares are absorbed by the company, reducing the number of outstanding shares on the market. Because there are fewer shares on the market, the relative ownership stake of each investor increases.

There are two ways that companies conduct a buyback: A tender offer or through the open market:

  1. Tender Offer: Corporate shareholders receive a tender offer that requests them to submit, or tender, a portion or all of their shares within a certain time frame. The offer states the number of shares the company wants to repurchase along with a price range for the shares. Investors who accept state how many shares they want to tender along with the price they are willing to accept. Once the company receives all the offers, it finds the right mix to buy the shares at the lowest cost.
  2. Open Market: A company can also buy its shares on the open market at the market price, which is often the case. But the announcement of a buyback causes the share price to shoot up because the market perceives it as a positive signal.

The Motives

Why do companies buy back shares? A firm's management is likely to say that a buyback is the best use of capital at that particular time. After all, the goal of a firm's management is to maximize return for shareholders, and a buyback typically increases shareholder value. The prototypical line in a buyback press release is "we don't see any better investment than in ourselves." Although this can sometimes be the case, this statement is not always true.

There are other sound motives that drive companies to repurchase shares. For example, management may feel the market has discounted its share price too steeply. A stock price can be pummeled by the market for many reasons such as weaker-than-expected earnings results, an accounting scandal, or just a poor overall economic climate. Thus, when a company spends millions of dollars buying up its own shares, it can be a sign that management believes that the market has gone too far in discounting the shares—a positive sign.

The market typically perceives a buyback as a positive indicator for a company, and the share price often shoots up following a buyback.

Improving Financial Ratios

A corporation may execute a share buyback to improve its financial ratios. These are the metrics that investors use to analyze a company's value. But this motivation is questionable. That's because reducing the number of shares may signal issues with management. But if a company's motive for initiating a buyback is sound, better financial ratios as a result could simply be a byproduct of a good corporate decision.

Let's look at how this happens:

Example

Suppose a company repurchases one million shares at $15 per share for a total cash outlay of $15 million. Below are the components of the ROA and earnings per share (EPS) calculations and how they change as a result of the buyback.

  Before Buyback After Buyback
Cash $20,000,000 $5,000,000
Assets $50,000,000 $35,000,000
Earnings $2,000,000 $2,000,000
Shares Outstanding 10,000,000 9,000,000
ROA 4.00% 5.71%
Earnings Per Share $0.20 $0.22

As you can see, the company's cash hoard was reduced from $20 million to $5 million. Because cash is an asset, this will lower the total assets of the company from $50 million to $35 million. This increases ROA, even though earnings don't change. Prior to the buyback, the company's ROA was 4% ($2 million ÷ $50 million). After the repurchase, ROA increases to 5.71% ($2 million ÷ $35 million). A similar effect can be seen for EPS, which increases from 20 cents ($2 million ÷ 10 million shares) to 22 cents ($2 million ÷ 9 million shares).

The buyback also improves the company's price-earnings ratio (P/E), which is one of the most well-known and often-used measures of value. At the risk of oversimplification, the market often thinks a lower P/E ratio is better. Therefore, if we assume that the shares remain at $15, the P/E ratio before the buyback is 75 ($15 ÷ 20 cents). After the buyback, the P/E decreases to 68 ($15 ÷ 22 cents) due to the reduction in outstanding shares. In other words, fewer shares + same earnings = higher EPS, which leads to a better P/E.

Based on the P/E ratio as a measure of value, the company is now less expensive per dollar of earnings than it was prior to the repurchase despite the fact there was no change in earnings.

Dilution

Another reason that a company may move forward with a buyback is to reduce the dilution that is often caused by generous employee stock option plans (ESOP).

Bull markets and strong economies often create a very competitive labor market. Companies have to compete to retain personnel, and ESOPs comprise many compensation packages. Stock options have the opposite effect of share repurchases as they increase the number of shares outstanding when the options are exercised.

As in the above example, a change in the number of outstanding shares can affect key financial measures such as EPS and P/E. In the case of dilution, a change in the number of outstanding shares has the opposite effect of repurchase: it weakens the financial appearance of the company.

If we assume that the shares in the company had increased by one million, the EPS would have fallen to 18 cents per share from 20 cents per share. After years of lucrative stock option programs, a company may decide to repurchase shares to avoid or eliminate excessive dilution.

Tax Benefit 

On Aug. 16, 2022, President Joe Biden signed the Inflation Reduction Act of 2022 into law. One of the provisions included an excise tax of 1% on share buybacks. The new rule goes into effect for repurchases after Dec. 31, 2022, that are valued at over $1 million. And it excludes stock that is reserved for new public issues and for employee stock or pension plans.

Prior to this, corporations generally weren't taxed at all if they repurchased their shares and boosted value for their shareholders. This is contrary to the tax treatment of dividends, which is a portion of a company's earnings distributed to shareholders. Dividends are taxed at ordinary income tax rates when received. Tax rates and their effects typically change annually. As such, investors consider the annual tax rate on capital gains versus dividends as ordinary income when looking at the benefits.

The idea for an excise tax was introduced by Ron Wyden (D-OR) and Sherrod Brown (D-OH). The Stock Buyback Accountability Act was introduced in the Senate in September 2021 and proposed a 2% tax on share buybacks. The bill aimed to address concerns that corporate executives used buybacks to benefit themselves by boosting share prices rather than investing in the economy and their workers.

The Bottom Line 

Are share buybacks good or bad? As is so often the case in finance, the question may not have a definitive answer. Buybacks reduce the number of shares outstanding and a company’s total assets, which can affect the company and its investors in many different ways. When you look at key ratios like EPS and P/E, a share decrease boosts EPS and lowers the P/E for a more attractive value. Ratios, such as ROA and ROE, improve because the denominator decreases, which increases the return.

In the public market, a buyback will always increase the stock’s value to the benefit of shareholders. However, investors should ask whether a company is merely using buybacks to prop up ratios, provide short-term relief to an ailing stock price, or get out from under excessive dilution.
