A real-life example of corporate divestment
In January 2023, GE (GE -1.19%) divested its healthcare technology business and formed a new company called GE HealthCare. It didn't do so because the business was failing. Rather, the subsidiary was doing well enough that it needed to become a distinct entity from its corporate parent to focus on its own growth.
GE shareholders got one share of GE HealthCare common stock for every three shares of GE common stock they held. So, if an investor held 90 shares of GE, they would end up with 30 shares of GE HealthCare.
Because it was a corporate spinoff, there were no tax consequences for this trade. Investors holding GE HealthCare now have ownership in a company with high growth potential in the health tech space. GE retained about 20% ownership, which was enough to be a controlling share in this situation.
