A carve-out, spin-off, and divestiture describe different ways a company can separate a business. In a carve-out IPO, investors buy shares in part of the business and the parent may retain a stake. In a spin-off, the parent distributes shares of a separated company to its shareholders. A divestiture is the broader act of disposing of a business; one common route is a sale to a buyer. The terms can overlap in a multi-step transaction, so the key is to follow the actual steps, ownership changes, and ongoing obligations.
How the three separation routes differ
| Route | What happens to ownership or proceeds | Work highlighted in the cited examples | Important distinction |
|---|---|---|---|
| Carve-out IPO | A portion of the business’s equity is offered to public investors. The parent may retain an ownership interest or later complete a fuller separation. | Prepare carve-out financial statements and standalone infrastructure, and coordinate the public offering and disclosures. | A carve-out may be a reporting or transaction step rather than the final separation. |
| Spin-off | Shares in the separated company are distributed to the parent’s existing shareholders, often pro rata. The parent may retain a stake depending on the structure. | Reorganize the business, prepare disclosure and distribution mechanics, and arrange ongoing relationships between the companies. | Tax treatment and completion depend on transaction-specific conditions and approvals. |
| Divestiture by sale | A buyer acquires a business or its assets, and the seller receives negotiated consideration. | The cited materials identify a sale process as an alternative, but do not provide a complete sale-execution checklist. | Divestiture is broader than a sale: it means disposing of a business, which may use different structures. |
These labels are not always mutually exclusive. A company could first sell shares in a carve-out IPO and later separate the remaining ownership, for example. FedEx disclosed considering a partial carve-out IPO of FedEx Freight followed by a possible full separation, as well as alternative spin-off structures; its selected plan described a pro rata share distribution. FedEx’s information statement describes those alternatives.

What the terms mean in practice
Carve-out: offer part of a business to investors
A carve-out IPO makes equity in a portion of a parent company’s business available to public investors. The parent can retain an interest, and the IPO may be one stage in a later, fuller separation. A business being carved out also needs financial reporting and operating infrastructure that can support its separate status. Darden’s 2014 investor presentation, for instance, described preparing carve-out audited financials and infrastructure while weighing a possible pro rata spin-off or a sale process for Red Lobster. This is a historical process example, not a statement of Red Lobster’s current status. Darden’s presentation gives that example.
Spin-off: distribute shares to existing shareholders
In a spin-off, the parent separates a business into a company and distributes shares of that company to its existing shareholders, commonly in proportion to their parent holdings. Depending on the transaction, the parent may keep some shares or none. Unlike an IPO, the defining ownership event is the distribution to existing shareholders, not a sale of shares to new public investors.

Divestiture: dispose of the business
Divestiture is the broadest of the three terms: it refers to disposing of a business. Selling it to a buyer is one route, with the seller receiving the consideration negotiated for that transaction. A divestiture should therefore not be treated as a synonym for a spin-off or for a sale alone.
How companies choose among the routes
The route depends on the intended ownership outcome and the business’s readiness to operate separately, as well as disclosure, approvals, taxes, and continuing dependencies. Useful questions include:
- Who should receive ownership or proceeds? An IPO brings in investors who buy offered shares; a spin-off gives shares to the parent’s shareholders; a sale transfers the business or assets to a buyer in exchange for negotiated consideration.
- Will the parent retain an interest? A carve-out IPO can leave the parent with shares, and a spin-off can be structured with a retained stake. The eventual ownership depends on the transaction design.
- Can the business stand alone? Consider whether it has separable financial statements, systems, people, and infrastructure. Darden’s example highlights financial and infrastructure preparation as part of carve-out planning.
- What disclosures, listings, and approvals are needed? Public offerings and spin-offs involve disclosure and transaction mechanics; the precise requirements depend on the transaction and applicable rules.
- What are the tax consequences and conditions? Tax treatment is not guaranteed by a transaction’s label. The company’s stated intent and the conditions attached to it matter.
- Which operational dependencies will continue? Identify services, employees, intellectual property, assets, liabilities, and other relationships that must be handled between the separated businesses.
FedEx’s disclosed alternatives illustrate that a board may compare a partial carve-out IPO followed by a possible full separation with different spin-off structures, while considering investor response and expected tax impact. Those are transaction-specific decision factors, not a universal formula for choosing a route.

A legal separation does not necessarily end practical ties between the companies. Agreements can allocate responsibilities and define which services or shared resources continue, and for how long. The Aptiv/Versigent SEC-filed materials describe contemplated agreements covering:
Rank #3
- Separation and distribution mechanics;
- Transition services between the companies;
- Tax matters;
- Employee matters; and
- Intellectual-property cross-licensing.
Other separation documents can address the allocation of assets, liabilities, rights, obligations, employee benefits, environmental matters, intellectual property, and tax-related matters. The agreements used in any specific transaction vary; the Aptiv/Versigent filing is an example, not a required checklist for every separation. Aptiv/Versigent’s filing describes the contemplated post-spin arrangements, while its separation agreement exhibit addresses allocations and related matters.

A spin-off is not automatically tax-free. A company may say a planned transaction is intended to qualify for tax-free treatment for U.S. federal income-tax purposes, but that wording describes an intention subject to conditions and approvals, not a universal outcome. Flex’s 2026 report describes its planned separation as intended to receive that treatment and subject to conditions and approvals. Flex’s 2026 report sets out that qualification. Aptiv/Versigent’s materials likewise explain the rationale for the intended tax treatment in their specific transaction. A reader assessing a real separation should look to the company’s filings and transaction documents for the stated tax treatment and its conditions.
