How Share Buybacks Affect Stock Performance

Public companies have several options to allocate their excess capital. They can invest in developing new products, acquiring other companies, paying off their debts, paying dividends to their shareholders, or repurchase their outstanding shares. Share buybacks are one of the most common methods of returning to shareholders.

By repurchasing their stocks, companies declare that they have confidence in their company’s future performance and that they are efficiently managing their capital. However, some people argue that this practice is detrimental to the company as it may focus more on the short-term financial metrics for their companies.

Despite the debate regarding the impacts of share buybacks on the companies that implement them, investors look to this practice to determine the companies’ long-term financial health.

What Is a Share Buyback?

A share buyback is when a company purchases its outstanding shares from the public market. These repurchased stocks are typically retired by the company.

Companies can use several different funds to finance share buybacks, including:

Existing cash

Cash flow from operations

Cash reserves

Borrowing money from financial institutions

By reducing the number of shares that are in circulation, several other company metrics are impacted.

Why Companies Repurchase Their Shares

Companies implement share buybacks for several reasons. The most common reasons for share buybacks include:

To return to shareholders the capital that the company has generated from its operations

To increase the earnings per share of their company’s stocks

To counteract the stocks that employees purchase with company compensation packages

To optimize the company’s capital structure

To signal the shareholders the company’s confidence in its future

To deploy the company’s excess cash

The effectiveness of implementing share buybacks depends on the company’s financial situation and the price of their stocks.

Buybacks and Earnings Per Share

The impact of share buybacks on a company’s earnings per share (EPS) is some of the most noticeable impacts that shareholders experience as a result.

Since a company has fewer shares outstanding in circulation after a share buyback:

Its EPS will be higher

Its profitability ratios will be improved

The company will receive more investor attention

Its valuation metrics will be improved

However, the increase in EPS that a company can experience as a result of share buybacks does not necessarily mean that the company is seeing an increase in its overall business performance.

Capital Allocation Matters

The decision to engage in share buybacks is just one aspect of a company’s overall capital allocation.

A company’s management team must determine how to allocate its capital towards:

Expanding its business

Developing new products

Paying off its debt

Paying dividends to shareholders

Making strategic acquisitions

Executing share buybacks

All of these aspects of capital allocation are essential for a company’s shareholders to experience an increased value in their shares over time.

Buybacks should support the company’s growth rather than become a way to replace the management of that company’s capital.

When Buybacks Create Value

Share buybacks are most effective when a company sells its shares at a value that is less than the shares’ intrinsic value.

By doing so, the company will:

Increase the stocks’ ownership for the remaining shareholders

Improve the company’s long-term returns

Improve its capital efficiency

Signal its management team’s confidence in the company and its future

By buying back its own shares at excessively high valuations, though, a company may reduce the future value of its shareholders.

Risks of Debt-Funded Share Buybacks

Some companies use debt to finance their share buybacks. While the practice may look great on a company’s financial statements in the short term, the additional financial leverage and interest expenses that the company incurs can be detrimental in the long term.

Investors should evaluate whether a company’s financial and capital structure can sustain the additional debt resulting from extensive share buyback programs. A company with strong cash flows can typically offer more flexibility to fund its share buybacks than if it relies on debt financing alone.

Buybacks Versus Dividends

Both share buybacks and dividend payments are a way for a company to return capital to its shareholders.

With share buybacks, a company can:

Increase its earnings per share

Reduce the number of shares that are in circulation

Have more flexibility in managing and financing its company

Improve the long-term appreciation of the company’s stocks

With dividends, a company can:

Provide its shareholders with a more regular source of income

Provide additional financial stability for the company and its shareholders

Show the level of the company’s returns on its shares

Many companies that have matured to significant sizes use both share buybacks and dividend payments to manage their capital and maximize the returns that they provide to shareholders.

Evaluating Share Buyback Programs

When determining whether a company should engage in share buybacks, investors should look beyond the company’s public announcement of the implementation of such a program.

Factors that should be evaluated include the company’s:

Cash flow

Balance sheet

Valuation of its stocks and shares

Total levels of debt

Share buybacks’ historical execution of the programs

Long-term commitment to capital allocation

Investors that carefully evaluate these factors will better understand the company’s management team and its overall financial management practices.

Key Takeaways

Companies implement share buybacks to reduce the number of their stocks that are in circulation.

Repurchasing the company’s stocks increases its earnings per share and returns the company’s profits to its shareholders.

Companies that buy back their stocks experience the greatest increase in value if it purchases its stocks when their value is less than the stocks’ intrinsic value.

Management teams must balance the allocation of a company’s capital towards its growth and returning profits to shareholders.

If a company uses debt to fund its share buyback programs, investors should evaluate the company’s financial position carefully.

Additionally, investors should evaluate the factors related to the company’s financial and capital structure, such as its cash flow, stock valuation, and financial strength.

Conclusion

Share buybacks are one of the most influential aspects of the capital allocation that a public company must manage. By effectively buying back its stocks, a public company can work to enhance the value of its shareholders’ stocks over the long term while also improving its financial metrics. However, to do so effectively, investors must understand how share buybacks fit into a company’s total capital allocation strategy and how it may impact the company’s future growth opportunities.
