Why would a company buy back its shares?

Companies buy back shares to return excess cash, reduce cost of capital, support stock prices, or repurchase undervalued equity.

Do buybacks benefit all shareholders?

They can, particularly when shares are undervalued. However, if buybacks replace innovation or are debt-funded, they may weaken long-term shareholder value.

How do investors evaluate a buyback program?

Check whether buybacks are funded from free cash flow, paired with reinvestment in growth, and supported by insider buying—these are signs of value-creating repurchases.

3 Reasons Why a Company Should Consider a Share Buyback

Q: Are buybacks still popular in 2025?

Yes. Despite the 1% excise tax and higher rates, buybacks remain a preferred method of returning capital. Companies are more selective but continue to deploy trillions annually.

Updated: August 2025

Share buybacks—when a company repurchases its own shares from the market—have become one of the most debated and widely used corporate finance strategies of the last two decades. Once overshadowed by dividends, buybacks have now surpassed them as the preferred way many companies return cash to shareholders.

In 2025, despite new regulations, higher interest rates, and the 1% U.S. excise tax on repurchases, companies continue to deploy trillions of dollars annually toward buybacks. Why? Because when used strategically, buybacks can strengthen balance sheets, stabilize stock prices, and reward long-term investors.

Here are three reasons companies should consider a buyback program:

1. Unused Cash Is Costly

Every share represents a small piece of ownership in the company. If management has no immediate opportunities to reinvest excess cash into high-growth projects, sitting on idle equity capital can weigh down shareholder returns.

Cost of equity: Investors expect a return—whether via dividends or capital appreciation. Holding unused capital dilutes ownership without generating productivity.
Reducing capital burden: Repurchasing shares lowers outstanding equity and can reduce the company’s cost of capital.
Real-world example: In 2024, Apple returned more than $100 billion via buybacks—not because it lacked innovation, but because its cash hoard exceeded immediate growth needs.

2. Preserving or Supporting the Stock Price

Shareholders value stability. A disciplined buyback program can support share prices during volatility and signal management’s confidence to the market.

Flexibility: Unlike dividends, buybacks can be increased or paused as market conditions shift.
Resilience: During downturns, buybacks can absorb selling pressure and prevent excessive stock declines.
Case in point: Many banks and industrial giants in 2023–2024 deployed buybacks to offset market weakness, balancing shareholder expectations with financial flexibility.

3. The Stock Is Undervalued

Perhaps the strongest reason to initiate a buyback is when management believes the market is mispricing its stock.

Undervaluation: Occurs when short-term headwinds, sensational news, or market pessimism overshadow strong fundamentals.
Smart allocation: Repurchasing undervalued shares can deliver outsized long-term returns once the market corrects.
Historic lesson: In 2010–2011, U.S. corporations aggressively repurchased shares while the market still reflected recessionary gloom—leading to huge gains when valuations normalized.

FAQ: Company Share Buybacks

Q: Why would a company buy back its own shares instead of paying dividends?
A: Buybacks offer more flexibility. Unlike dividends, they can be adjusted without long-term commitment and may be more tax-efficient for shareholders.

Q: Do buybacks always benefit shareholders?
A: Not necessarily. Buybacks funded by free cash flow can enhance long-term value. But debt-fueled buybacks or those that replace R&D spending can weaken a company.

Q: Are buybacks still popular in 2025 despite new taxes?
A: Yes. Even with a 1% excise tax, companies continue to prioritize buybacks, though they are more selective given higher interest rates.

Q: How do investors know if a buyback is a good signal?
A: Look for sustained profitability, insider buying alongside repurchases, and management’s commitment to innovation. These often separate “value-creating” buybacks from short-term stock manipulation.
