Subsidiary spin-off
A subsidiary spin-off is when a large company separates one of its divisions into an independent, publicly traded company. The parent company distributes shares of the new company to its existing shareholders, who then own both the original company and the new one. You'll see this announced in SEC filings and news releases when management decides a business unit will thrive better on its own. It matters because spin-offs can unlock hidden value—the new company might be valued higher as a standalone business than as part of a larger conglomerate. For example, if TechCorp spun off its software division as SoftCorp Inc., TechCorp shareholders would automatically receive SoftCorp shares, creating two separate investment opportunities.
