Carve-Out vs. Spin-Off:
How Corporate Divestitures Actually Differ

In a carve-out (also called a partial sale), the parent company sells a business unit or subsidiary to a third-party buyer for cash. The parent company receives proceeds and retains no ownership in the carved-out business. In a spin-off, the parent company distributes shares of the separated business unit to its own shareholders pro-rata. No cash changes hands - the parent's shareholders simply end up owning shares of both the parent and the new standalone company. Carve-outs involve a buyer and a sale. Spin-offs redistribute ownership within the existing shareholder base.

In a spin-off, all shareholders of the parent receive shares of the new entity pro-rata. In a split-off, shareholders of the parent have the option to exchange their parent shares for shares of the new entity - not everyone participates. The parent repurchases some of its own shares in the process (those surrendered by shareholders who chose to exchange). Split-offs are less common but can be useful when the parent wants to reduce its share count and certain shareholders prefer the new entity's business to the parent's remaining operations.

Spin-offs can be structured as tax-free transactions under Section 355 of the Internal Revenue Code if they meet specific requirements: both the parent and the distributed subsidiary must have conducted an active trade or business for at least 5 years prior to the distribution, the transaction must not be used primarily as a device to distribute earnings and profits, and there must be a valid business purpose. A Section 355 opinion from outside tax counsel is typically required for the board to proceed. If the requirements are not met, the spin-off is taxable to both the parent (on the distributed gain) and to shareholders (as a dividend or capital gain).

A carve-out makes more sense when: the parent company needs cash (spin-offs produce no proceeds), when a specific buyer can create more value in the carved-out business than a standalone public company could, when the business is not large enough to support an independent public company, or when the parent wants a complete exit from a business unit without maintaining any relationship. Spin-offs are preferred when: the parent wants to separate two distinct businesses to allow each to trade independently (the classic 'conglomerate discount' remedy), when no compelling third-party buyer exists, or when the parent's shareholders would benefit from direct ownership of the separated business.

A carve-out IPO is a hybrid where the parent takes a subsidiary public by selling a minority stake in an IPO, while retaining majority ownership. This gives the subsidiary independent public currency (stock it can use for acquisitions, equity compensation) while letting the parent retain control and benefit from the subsidiary's eventual appreciation. The parent often intends to fully spin off the subsidiary later once it has established a trading history. This is sometimes called a 'two-step transaction' - partial IPO carve-out followed by a Section 355 spin-off of the remaining stake.
