What Is a Carve-Out? The M&A Meaning, Explained

In mergers and acquisitions, a carve-out is the separation of a business unit from its parent company so the unit can be sold, distributed to the parent's shareholders, or listed on its own. The unit usually has no legal entity of its own, no separate financial statements, and no dedicated systems, so it has to be extracted from shared contracts, shared people, and shared infrastructure before anyone else can run it. That extraction is the work of a carve-out: drawing the perimeter, building carve-out financial statements, sizing standalone cost, and agreeing a transition services agreement for whatever is not ready on the day the deal closes. In insurance and in contracts the word means something else: a benefit administered outside the main plan, or an exception written into a clause. This article covers the M&A meaning.

Carve-out (M&A): the separation of a business that has never operated on its own from its parent company, so it can be sold to a buyer, distributed to the parent's shareholders, or partly listed in an IPO. The carve-out is complete when the separated business runs on its own people, contracts, and systems and the last transition service has ended.

How is a carve-out different from a divestiture, spin-off, or split-off?

A divestiture is any exit from a business the parent owns. A carve-out is the separation work a divestiture needs when the business was never a separate company. Selling a subsidiary that already files its own financial statements and runs its own ERP is a divestiture with no carve-out attached, and it takes far less work to close. Spin-offs, split-offs, and equity carve-outs change who owns the business afterward and how money moves, but most of them sit on top of the same separation work.

The tax column often decides the route. A spin-off or split-off that meets Section 355 of the Internal Revenue Code lets the parent's shareholders receive stock in the new company without recognizing gain, and a cash sale offers no such treatment. An equity carve-out can be the first step toward a spin-off, which is why the size of the IPO matters. An IPO that takes the parent's stake below 80 percent gives up the control a later tax-free distribution requires under Section 368(c), and the 80 percent vote-and-value test for keeping the subsidiary in the parent's consolidated federal return under Section 1504(a)(2). Our comparison of a divestiture versus a spin-off covers how boards choose between a sale and a spin, and our divestiture consulting practice runs every one of these routes.

Why is the perimeter the hard part?

The perimeter is the line that defines what goes with the business and what stays with the parent: legal entities, customer contracts, supplier agreements, intellectual property, employees, real estate, licenses, data, and liabilities. Drawing it is the first task in a carve-out, and it sets the cost of everything after it.

Perimeter decisions are hard because the business was never built to have edges. A salesperson sells the divested product and three retained ones, a master supply agreement prices volume neither half will reach alone, and a factory makes goods for both businesses on the same lines. Each needs an answer, and each answer has a price: a contract that cannot be split becomes a supply agreement between the two companies, and a factory that cannot be divided becomes a manufacturing services arrangement with a term and a margin.

Sellers who defer these decisions until a buyer is in confirmatory diligence pay twice: the financials and the standalone cost model get rebuilt, and the buyer widens its risk assumptions in the meantime. Settle and document the perimeter before the information memorandum goes out.

What are carve-out financial statements?

A carved-out business has no financial history of its own, so someone has to construct one. Carve-out financial statements present the business's revenue, costs, assets, and liabilities as though it had operated on its own for the periods presented. The SEC staff's position in Staff Accounting Bulletin Topic 1.B.1 is that historical statements should reflect all of the business's costs of doing business, including costs the parent paid on its behalf, with the allocation method explained in the notes.

Audited carve-out statements are required when the separated business registers with the SEC, as in a spin-off on Form 10 or a carve-out IPO, and when a public buyer acquires a business that exceeds 20 percent on a significance test under Regulation S-X Rule 3-05. Private deals carry no such rule, but buyers and lenders expect the statements before they price the business, and our carve-out financial statements guide covers how they are built and audited.

What are standalone costs and dis-synergies?

The number that moves carve-out valuations most is the gap between allocated cost and standalone cost. The parent's books charge the business an allocation for corporate services, calculated by a formula built for internal management reporting. That allocation reflects the parent's scale, the parent's contract pricing, and the parent's shared headcount, none of which the business keeps after close.

Standalone cost is what the business has to spend to replace those services: its own finance and HR teams, audit and insurance, software licenses at single-company pricing, and security operations. The difference is a dis-synergy, and because it recurs every year it comes out of EBITDA, so its effect on price is the gap multiplied by the valuation multiple. A credible standalone cost model is built bottom-up from the services the business consumes, priced against real quotes and real headcount plans, before buyers ask for it. A model built by discounting the allocation gets treated as advocacy and set aside.

The parent has its own version of the problem. When the unit leaves, the overhead it absorbed stays behind as stranded cost, and Deloitte found that most companies see their EBITDA margin fall in the 12 months after a divestment and take nearly three years on average to recover (Deloitte, March 2025). Our guide to stranded costs after a divestiture covers the seller's side.

How does a transition services agreement work in a carve-out?

No carve-out is operationally separate at close. A transition services agreement obligates the seller to keep providing named services to the divested business after the deal is done, such as payroll processing, ERP access, help desk, hosting, and security monitoring. BCG reports that TSAs are typically in effect for 3 to 24 months after closing (BCG, June 2021), and PwC describes 12 to 24 months as the typical time to exit a TSA (PwC, November 2023). Deloitte notes that it is not unusual for the seller to add a modest single-digit markup to the actual cost of the services (Deloitte).

The mistake to avoid is setting the term before the separation plan exists: a 12-month agreement signed against an 18-month IT separation forces extension negotiations and leaves the seller's IT team running two companies longer than it budgeted. Our transition services agreement guide covers scope and pricing, and our Day 1 readiness checklist covers everything that has to work the morning after close.

What breaks in a carve-out?

In our experience, five entanglements cause most of the delay and unbudgeted cost in a carve-out, and each of them can be found months before close. Dealmakers name separation as a hurdle as well. KPMG's 2026 survey of 700 dealmakers found material hurdles that included operational separation, cited by 52 percent, and valuation complexity, cited by 43 percent, and 40 percent of those surveyed said IT and data separation remains a concern (Consulting.us, April 8, 2026).

A shared ERP with no clean data partition is the largest. When the business exists as company codes inside one SAP or Oracle instance with commingled master data, extraction means a new instance, a data migration, and a cutover weekend with a rollback plan. Enterprise software licenses are the second: the parent signed them, many restrict assignment, and the carved-out business ends up negotiating its own agreements on a deadline at single-company volume.

Change-of-control clauses in customer and supplier contracts are the third, because each consent request that arrives during a sale invites renegotiation. One payroll system covering both employee populations is the fourth: the divested employees need payroll and benefits that work for the first post-close pay run, either in a new environment or under a transition service. A single identity directory is the fifth. When everyone signs in through one Active Directory or Entra tenant, separation means a new tenant, new accounts, new device enrollment, and re-integration of every application that trusted the old directory. Our IT carve-out services handle that separation, and our article on IT carve-outs covers the patterns in depth.

Security belongs on the same list. The parent's endpoint protection, monitoring, identity controls, and compliance attestations stop at the perimeter, so the new company needs its own security program running before the transition services end. Our carve-out cybersecurity work builds that program, and our semiconductor carve-out case study shows what it involves across five workstreams.

Why do private equity firms buy carve-outs?

Carve-outs are a steady source of private equity deals because the difficulty narrows the field. Many buyers will not underwrite separation risk, a thinner field can mean a better entry price, and a business that competed with other divisions for capital may have been short of investment for years. PitchBook data cited by FTI Consulting put carve-outs and divestitures at 12.6 percent of U.S. private equity buyouts in the first quarter of 2024, up from an all-time low of 5.7 percent in the fourth quarter of 2021 (FTI Consulting, January 2025).

The returns are harder to earn than they were. Bain found that private equity carve-outs made before 2012 returned about 3.0 times invested capital on average, while the average carve-out since 2012 has returned 1.5 times, and it pointed to weaker operational gains, tougher competition, and higher prices (Bain & Company, March 2025). Separation is where a sponsor can lose more ground: a fund that inherits a badly drawn perimeter, an optimistic standalone cost model, or a short TSA spends its first years fixing the carve-out instead of running its value creation plan. Our guide to private equity carve-outs covers the buyer's side.

Frequently asked questions

What is a carve-out in M&A? A carve-out is the separation of a business unit from its parent so the unit can be sold, distributed to the parent's shareholders, or partly listed in an IPO. Because the unit has never operated alone, the work covers the perimeter, carve-out financial statements, standalone costs, systems, and a transition services agreement for whatever is not ready at closing.

What is the difference between a carve-out and a spin-off? A carve-out is the separation work, and a spin-off is one way to finish it. In a spin-off the parent distributes shares of the separated company to its own shareholders instead of selling it, and the distribution can be tax-free to them under Section 355 of the Internal Revenue Code. A carve-out sale ends with a buyer owning the business and the parent holding cash.

What is an equity carve-out? An equity carve-out is an IPO of a minority stake in a subsidiary while the parent keeps control. A parent that wants to keep the option of a later tax-free spin-off has to keep control of the subsidiary as defined in Section 368(c) of the Internal Revenue Code: at least 80 percent of the combined voting power and at least 80 percent of the shares of all other classes of stock. That limits how much of the subsidiary the IPO can place with public investors.

How long does a carve-out take? The transaction itself can sign and close within months: Deloitte's 2026 Global Divestiture Survey puts the median time from signing to closing at about three months. Operational separation runs longer, and BCG reports that transition services agreements are typically in effect for 3 to 24 months after closing.

What is a transition services agreement in a carve-out? A transition services agreement obligates the seller to keep providing named services, such as payroll, ERP access, hosting, and help desk, to the divested business for a set period after closing. Each service carries a price, a duration, and exit criteria, and the term should come from the separation plan rather than from a preferred closing date.

How we work on carve-outs

BD Emerson (now Andersen Consulting) works carve-outs from both sides. For sellers, that means perimeter definition, carve-out financial statements, a bottom-up standalone cost model, transition services scoping and pricing, Day 1 readiness, and the stranded cost takeout after the services end. For buyers, it means sizing the separation before the price is set, then running IT separation and the new company's security program. Because the financial, tax, technology, and cyber workstreams run under one firm, the findings reconcile to a single model.

The first deliverable is a documented perimeter and an inventory of what the business shares with its parent, because every timeline, transition services term, and standalone cost number starts from that list. Our carve-out advisory team builds it first.
