After a large, debt-funded acquisition, deleveraging should be the top priority over share buybacks. Choosing buybacks sends a mixed signal, disappoints investors expecting a return to the growth playbook, and leaves the company too financially constrained to pursue future strategic M&A opportunities.

Companies often announce and execute buybacks to appease the market, not because their stock is undervalued. This programmatic repurchasing, especially at cyclical peaks, destroys value. Truly value-accretive buybacks are rare because most managers lack the capital allocation skill to time them effectively.

Since the 1990s, U.S. companies have returned more capital through stock buybacks than dividends. An investor focused solely on dividend yield is missing the larger part of the shareholder return story and cannot accurately assess a company's total capital allocation strategy.

Despite strong performance in Parks and streaming, Disney's stock is flat because the market values the entire conglomerate based on its weakest segment: declining linear networks. Spinning off these "bad bank" assets would unlock the true value of the high-growth divisions.

Despite S&P 500 companies spending over a trillion dollars on share repurchases, the aggregate share count has not meaningfully decreased in 25 years. These buybacks primarily serve to counteract the massive stock dilution from executive compensation, creating an illusion of shareholder return while enriching insiders and levitating stock prices.

The market added $125 billion to Amazon's market cap after it announced its $11.6 billion acquisition of Globalstar. This shows that for strategic M&A, investors value the future market positioning and competitive moat far more than the target company's standalone worth, rewarding the acquirer's bold vision.

Companies termed "share cannibals" aggressively repurchase their own shares, especially when undervalued. This capital allocation strategy is often superior to dividends because it transfers value from sellers to long-term shareholders and acts as a high-return, low-risk investment in the company's own business.

As illustrated by SpaceX's $60B acquisition of Cursor, a high valuation is more than a vanity metric; it's powerful M&A currency. It allows a company to make large, strategically vital acquisitions with less shareholder dilution, effectively turning market perception into a tangible competitive advantage.

Inspired by baseball's 'Wins Above Replacement' (WAR) metric, M&A should be evaluated not against doing nothing, but against a 'replacement-level' use of capital, such as a share buyback. A buyback is a readily available, low-risk alternative that most acquisitions fail to clear as a comparable benchmark.
