What is Share Buyback?

Companies execute buybacks through open market purchases (the most common method, buying shares gradually on the exchange), accelerated share repurchase programs (ASR, buying a large block through an investment bank), or tender offers (offering to buy shares at a premium from willing shareholders). In 2023, S&P 500 companies spent approximately $800 billion on buybacks.

Buybacks are often considered more tax-efficient than dividends for returning capital to shareholders. Dividends are taxed immediately when received, while buybacks increase the stock price, deferring taxes until the investor sells. This is why many companies, particularly in technology, prefer buybacks over dividends. However, the Inflation Reduction Act of 2022 imposed a 1% excise tax on corporate buybacks.

The quality of buybacks matters enormously. Companies that buy back shares when their stock is undervalued create significant shareholder value. Those that buy back shares at elevated valuations destroy value — they spend more per share than the shares are worth. Unfortunately, studies show that aggregate buyback activity peaks near market tops and declines near market bottoms, suggesting poor timing overall.

Critics argue that excessive buybacks come at the expense of investment in R&D, capital expenditure, and employee compensation. Others point out that buybacks funded by debt merely increase financial leverage without creating real value. The best buyback programs are funded by genuine free cash flow at prices below intrinsic value.
