Equity carve-out

Equity carve-out (ECO), also known as a split-off IPO or a partial spin-off, is a type of corporate reorganization, in which a company creates a new subsidiary and subsequently IPOs it, while retaining management control. Only part of the shares are offered to the public, so the parent company retains an equity stake in the subsidiary. Typically, up to 20% of subsidiary shares is offered to the public.
