It takes courage to break up a company. CEOs and boards of directors often fear that investors will view asset divestitures as admissions of failed strategy—that having certain businesses under the same corporate umbrella never made sense. Many worry that shedding assets will cost a company the benefits of scale, cut into the advantages of analyst coverage, or even damage employee morale. Spin-offs in particular draw scrutiny because they shrink the size of the parent company but, unlike sales, don’t generate cash to reinvest.

We don’t believe these arguments hold up. What’s more, they may lead executives to pass up value-creating opportunities. A fundamental principle of corporate finance holds that a business creates the most value for shareholders and the economy as a whole when it is owned by the best—or, at least, a better—owner.¹ So it makes sense that companies should continually reallocate their resources as circumstances change. Moreover, the benefits of being part of a large company come at a cost; in fact, many spun-off companies can make substantial cuts in overhead costs once they are independent. Investors typically don’t care about a company being too small once it reaches a threshold of about $500 million in market capitalization.² And in our experience, executives and employees of spun-off companies often feel liberated and quite happy to be on their own.
