What is Carve-out?

A parent company sells part of a subsidiary in an IPO, keeping a stake.

A carve-out is when a parent company sells a minority stake in one of its subsidiaries to the public through an IPO, while keeping control. It lets the parent raise cash and put a public market value on the unit without fully letting go — a partial, rather than complete, separation.

Investors sometimes watch carve-outs because a smaller, focused business can be valued differently once it trades on its own than it was while buried inside a sprawling parent. The carve-out can reveal a hidden gem the market wasn't crediting, or a weaker unit the parent wanted to offload some of. It's often a first step, sometimes followed later by a full spin-off of the remaining stake.

In a carve-out a parent floats a minority stake in a subsidiary via IPO — here 20% — while keeping 80% and control. A partial separation that puts a public value on the unit.

For example

A conglomerate sells 20% of its fast-growing software division in an IPO, keeping 80% — raising cash and letting the market price that unit separately.

Why it matters to you

Carve-outs matter because they can surface value that a diversified parent's share price obscured, and because they change what you own. A parent that carves out a high-growth unit may see the market re-rate both pieces, while the newly listed subsidiary trades on its own merits. For investors, carve-outs (and the spin-offs that sometimes follow) are a recurring source of situations where the sum of the parts is worth more than the whole.

⚠ Assuming a carve-out is a clean separation

In a carve-out the parent keeps control and usually the majority stake, so the subsidiary isn't truly independent — its strategy, board, and dealings can still be steered by the parent, sometimes not in minority holders' favour. Treating a carved-out unit as a fully standalone business overlooks the conflicts that come with a controlling parent still in the picture.

Frequently asked questions

What is a carve-out?

A carve-out is when a parent company sells a minority stake in a subsidiary to the public via an IPO while keeping control. It raises cash and establishes a public market value for the unit, without the parent fully separating from it. The parent retains a majority stake.

What's the difference between a carve-out and a spin-off?

In a carve-out, the parent sells a minority stake to the public for cash and keeps control. In a spin-off, the parent distributes shares of the subsidiary to its existing shareholders, creating a fully separate company and raising no cash. A carve-out is partial; a spin-off is a clean separation.

Why do companies do carve-outs?

To raise cash, highlight the value of a unit the market may be underrating within the larger company, and give the subsidiary its own currency and profile — all while retaining control. A carve-out can also be a first step toward a later full separation, such as a spin-off of the remaining stake.
