Understanding Carve-Outs in Business Strategy: Key Definitions and Examples
By Markets & Investing DeskUpdated Nov 10, 2026
Definition
A carve-out is a deal in which a parent company separates a business unit and sells part of it to outside investors, usually through an IPO, while often keeping a controlling stake.
Key takeaways
- Unlike a spinoff, a carve-out brings in cash because shares are sold to new investors.
- Primary shares send IPO proceeds to the subsidiary, while secondary shares send them to the parent.
- A parent must keep at least 80% control to preserve the option of a later tax-free spinoff under Section 355.
- Buyers of carved-out units model standalone costs because historical statements may show allocated costs.
A carve-out is a transaction in which a parent company separates a subsidiary or business unit from the rest of the company and sells part of it to outside investors, most often through an initial public offering (IPO). The parent usually keeps a stake, frequently a controlling one, while the carved-out business becomes a standalone company with its own shareholders, board of directors and financial statements. Because shares are sold for cash, a carve-out brings money in, which is the main thing that separates it from a spinoff.
In M&A practice, “carve-out” is also used more broadly for any sale of a division that has to be separated from its parent before a buyer can own it, such as a private equity firm acquiring a single unit of a large conglomerate.
How a carve-out works
The process starts with separation. The parent decides which assets, employees, contracts, intellectual property and liabilities belong to the unit, places them in a distinct legal entity, and prepares standalone financial statements for it. The new company also needs its own governance: a board, management team and reporting functions.
Next comes the offering. Shares can be sold in two ways, and the difference determines who receives the cash:
- Primary shares: the subsidiary issues new shares, and the proceeds go to the subsidiary. The parent’s percentage falls because the share count rises.
- Secondary shares: the parent sells shares it already owns, and the proceeds go to the parent.
After the IPO, the parent typically remains the largest shareholder and often supplies resources and strategic support. The two companies commonly sign agreements covering shared services, supply arrangements or brand use during the transition.
The 80% threshold
Many carve-outs are a first step toward complete separation. Under Internal Revenue Code Section 355, a parent can distribute a subsidiary’s shares to its own shareholders tax-free only if, among other conditions, it has control as defined in Section 368(c): at least 80% of total combined voting power and at least 80% of each other class of stock. A parent that wants to keep this option open therefore generally offers no more than 20% of the subsidiary in the IPO.
Example: carve-out of a retail business
Hypothetical example, for illustration only.
ParentCo owns 100% of RetailCo, which has 100 million shares outstanding. ParentCo wants cash for RetailCo’s store expansion and a market valuation for the unit, but wants to keep control and the option of a tax-free spinoff.
Option A: primary offering. RetailCo issues 25 million new shares at $20.
- Proceeds to RetailCo: 25 million × $20 = $500 million
- Shares outstanding after the IPO: 125 million
- ParentCo’s stake: 100 ÷ 125 = 80%
- Implied equity value at the offer price: 125 million × $20 = $2.5 billion, so ParentCo’s stake is worth $2.0 billion
Option B: secondary offering. ParentCo sells 25 million of its existing shares at $20.
- Proceeds to ParentCo: $500 million
- Shares outstanding: still 100 million
- ParentCo’s stake: 75%
Both options raise the same $500 million at the same price, but Option B puts the cash in ParentCo’s hands and drops its stake below 80%, which would block a later tax-free spinoff under the control test. Option A keeps ParentCo exactly at the threshold, though the money stays inside RetailCo. The example ignores underwriting fees and taxes.
Why companies use carve-outs
- Raising capital without a full sale. The parent or subsidiary receives cash while the parent keeps most of the economics and control.
- Revealing value. A unit buried inside a larger company gets its own share price, giving investors a direct reading on what it is worth.
- Separate access to capital. A standalone company raises equity and debt on its own terms, and its cost of capital reflects its own risk rather than the parent’s blended profile.
- Staging an exit. A parent with no single buyer for the whole unit can sell part now and the rest over several years.
- Protecting an integrated business. When a unit relies heavily on the parent’s operations, a partial separation lets ties loosen gradually instead of damaging it with an abrupt full sale.
- Management incentives. The subsidiary can pay executives in its own stock, tying compensation to its own results.
Carve-out vs. spinoff vs. divestiture
| Feature | Equity carve-out | Spinoff | Outright divestiture |
|---|---|---|---|
| How shares change hands | Sold to new investors, usually via IPO | Distributed to the parent’s existing shareholders | Sold to a single buyer |
| Cash to the seller | Yes | Generally none | Yes |
| Parent’s stake afterward | Usually retains a majority | None or a residual stake | Usually none |
| New shareholders | Yes | No; existing holders own two companies | The buyer |
In a spinoff, the parent’s shareholders receive shares of the new company and end up owning both. To be tax-free, the parent must distribute at least 80%, giving up control.
Carve-outs in acquisitions
A buyer of a carve-out acquires a business that has never operated alone and may share IT systems, payroll, procurement, facilities and customer contracts with the seller. Deals therefore commonly include transition services agreements, under which the seller keeps providing those functions for a set period while the buyer builds replacements. Buyers also model standalone costs, the expense of replicating services the parent used to provide, because historical financial statements may show allocated rather than actual costs. These costs feed into the buyer’s IRR and pricing.
Limitations and risks
- Conflicts of interest. A controlling parent can steer decisions on pricing, intercompany contracts or capital allocation in its own favor, at the expense of minority shareholders.
- Dependence on the parent. A carved-out company that relies on parent services or customers faces disruption if the parent later cuts ties.
- Separation cost and complexity. Building standalone systems, staff and reporting takes time and money.
- Motive matters. Investors should ask why the parent is selling. A carve-out can unlock value, but it can also be a way to raise money from a weaker or non-core unit.
- Limited float. If only a small portion of shares trades publicly, the stock may be less liquid than a fully independent company of similar size.
The Bottom Line
Carve-outs matter to parent companies weighing how to raise money from a unit and to investors buying shares in one. A parent can collect cash, put a market price on the business and keep control, but share structure decides who gets the proceeds and whether a tax-free spinoff stays possible. Investors should examine why the parent is selling and how much the new company still depends on it.
