What is the main difference between an asset purchase and a share purchase?

A share purchase buys the company itself — its shares, and everything the company owns or owes, known or unknown. An asset purchase buys specified assets and liabilities named in the agreement, leaving the rest with the seller's existing company.

Why do buyers often prefer asset purchases?

Because they can choose exactly what to take on and can exclude liabilities they do not want to inherit — historic disputes, undisclosed tax exposure, a loss-making division. The trade-off is more administrative work: contracts often need consent to assign, and UK employees usually transfer under TUPE rather than automatically.

Why do sellers often prefer share purchases?

A share sale is a clean exit from the whole entity — the seller's company continues under new ownership rather than being wound down, and liabilities that were never disclosed generally stay with the company rather than resurfacing against the seller personally, subject to whatever warranties were given.

Do employees transfer in an asset purchase?

In the UK, usually yes, under TUPE — employees assigned to the transferring part of the business move to the buyer with continuity of service and existing terms protected, regardless of what the sale agreement says. In a share purchase employees are unaffected because their employer, the company, has not changed.

Is one structure always better for tax?

No, and this guide deliberately does not state specific rates. The tax outcome for both buyer and seller depends on the entities, the assets involved and current rules, and needs a tax adviser on the specific transaction rather than a general answer.

Does the due diligence scope change with the structure?

Yes. A share deal needs comprehensive diligence across the whole entity, because the whole entity is what is being bought. An asset deal narrows to clean title, ownership and assignability on each specific asset in the schedule.

Asset Purchase vs Share Purchase: Which Structure to Use

What each structure actually transfers, why buyers and sellers tend to prefer different ones, and how due diligence and consideration change with the choice.

By TrueValue12 September 20269 min read

Key takeaways

A share purchase transfers ownership of the company itself — its assets, its contracts and every liability it carries, known or not. An asset purchase transfers only the specific assets and liabilities named in the agreement.
Because a share purchase inherits unknown liabilities, buyers lean towards asset purchases where they can; sellers lean towards share purchases because they cleanly exit the whole entity, historic liabilities included.
An asset purchase can require third-party consent to assign contracts and, in the UK, usually triggers TUPE for the employees who work in the transferred part of the business — a share purchase does neither, because the employer never changes.
Which structure applies changes what due diligence has to prove: a share deal needs comprehensive warranties covering the whole entity; an asset deal needs clean title and assignability on each asset being bought.
The choice is commercial and legal before it is a form to fill in, and the tax consequences differ for buyer and seller in ways that depend on the specific circumstances — this is a decision to take with an adviser, not a default to assume.

The core difference

A share purchase buys the company itself: its shares change hands, the legal entity carries on exactly as it was, with the same contracts, the same employees, the same bank accounts and every liability it has ever taken on, disclosed or not. An asset purchase buys specific things out of the company — the premises, the equipment, the customer contracts, the brand, chosen stock — leaving the seller's company, and whatever the buyer did not choose to take, behind. The company that sold the assets still exists afterwards; the company whose shares were sold does not change hands as a separate legal question, because it is the thing that changed hands.

Buying the shares means buying the company as it stands, including everything on and off its balance sheet: its debts, its pension obligations, its tax history, any claim that has not yet been made against it, and any contract it has signed — good or bad. Nothing has to be individually assigned or consented to, because the counterparty to every contract is still the same legal entity; only its owner has changed. That is the structure's main attraction to a buyer who wants continuity with no interruption to customer or supplier relationships, and its main risk: a liability nobody knew about at completion still belongs to the buyer, which is why share purchase agreements carry extensive warranties and indemnities, and why due diligence on a share deal has to be comprehensive rather than targeted.

What an asset purchase transfers

Buying assets means the agreement names exactly what moves: specified equipment, premises (by lease assignment or freehold transfer), intellectual property, customer contracts, stock, and — usually deliberately — excludes named liabilities such as historic tax exposure, pending litigation or debt the buyer has no interest in inheriting. The seller's company remains liable for anything left behind, and eventually winds down or is repurposed once its sale proceeds are distributed. The buyer gets a clean starting point on the things they chose to buy, at the cost of having to actually move each one: a contract with a customer or supplier typically needs either their consent to assign it or a fresh contract altogether, a commercial lease needs the landlord's consent to assign, and in the UK the employees who work in the part of the business being sold are usually protected by the Transfer of Undertakings (Protection of Employment) Regulations (TUPE), which carries their employment, continuity of service and terms across to the buyer regardless of what the sale agreement says about them.

The two structures, side by side

What changes depending on which structure is used
	Share purchase	Asset purchase
What is bought	The company itself, via its shares	Specified assets and liabilities, named in the agreement
Liability exposure	Every liability the company carries, known or unknown, unless specifically excluded and indemnified	Only what is expressly assumed; other liabilities stay with the seller's company
Contracts	Transfer automatically — the counterparty is unchanged	Usually need third-party consent to assign, or a new contract
Employees (UK)	Unaffected — the employer does not change	Usually transfer under TUPE, with continuity of service and existing terms preserved
Due diligence focus	Comprehensive: the whole entity, its history and every contract it holds	Targeted: clean title and assignability on each asset being bought
Completion mechanics	Simpler on paper — shares change hands in one transaction	More moving parts — each asset class, consent and novation handled separately
Typical preference	Often preferred by sellers, and by buyers who want continuity with no gaps	Often preferred by buyers who want to exclude historic risk or buy only part of a business

Why buyer and seller preferences typically diverge

A seller who sells shares is out, completely, with the liabilities of the business now somebody else's problem — which is exactly why a buyer's adviser pushes hard on warranties and indemnities in a share deal, and why a warranty and indemnity insurance market exists at all. A buyer who is only interested in part of a business — one division, one site, the customer list and the brand, but not a legacy defined-benefit pension scheme or a dispute from three years ago — usually cannot get that through a share purchase, because shares carry the whole company. An asset purchase lets the buyer choose. It is also the natural structure where the seller is not selling their whole company: a group disposing of one subsidiary's trading operations, or a sole trader whose "business" was never incorporated in the first place, since there are then no shares to sell.

Neither preference is universal. A buyer who values continuity of customer contracts above all else — a services business where re-papering every client agreement would itself damage the relationships being bought — may prefer a share deal despite the inherited risk, and price or insure that risk instead of trying to structure around it.

Due diligence differs by structure

A share deal's due diligence has to cover the whole entity because the whole entity is what changes hands: full financial history, every contract on the books, litigation, employment claims, tax filings, regulatory standing, and anything in the company's past that could surface as a liability later. An asset deal narrows the question to each asset in the schedule: is title clean, is it actually owned by the seller, can it be assigned, and what does it come with (a lease with restrictive covenants, IP with a co-owner, equipment on finance). It is a smaller question asked more precisely, rather than a smaller amount of work — a poorly scoped asset schedule creates its own risk, in the form of an asset everyone assumed was included that turns out not to be.

A worked example

Illustrative scenario

A buyer is looking at a facilities-management company with two divisions: a profitable commercial-cleaning contract book, and a loss-making events-staffing arm the buyer has no interest in, plus a legacy dispute with a former supplier that predates current management. A share purchase would bring the whole company — both divisions and the dispute — across in one transaction, needing warranties to cover the dispute and a price adjustment or indemnity if it resolves badly. An asset purchase lets the buyer take only the commercial-cleaning contracts, the related equipment and the staff who deliver them (who transfer under TUPE), leaving the events-staffing arm and the dispute with the seller's existing company. The second route needs each cleaning contract's client consent to assign and a TUPE process for the transferring staff — more administrative steps, in exchange for not buying a dispute that has nothing to do with the business being acquired.

Common mistakes

Assuming the structure is a drafting detail. It changes what due diligence has to prove, what needs third-party consent, whether TUPE applies, and who is exposed if something was missed. Decide early — it shapes the whole process, not just the completion documents.
Treating a share deal's warranties as a substitute for diligence. A warranty is a promise to compensate if something turns out to be untrue; it is not a guarantee the buyer will ever collect, particularly against a seller who has since spent the proceeds. It supplements diligence, not replaces it.
Missing that a contract needs consent to assign. An asset purchase agreement can list a customer contract as a transferring asset; it does not thereby transfer if the contract itself requires the counterparty's consent and that consent was never sought.
Getting TUPE wrong, or ignoring it. In a UK asset purchase, assuming employees simply do not transfer — or that new terms can simply be imposed after completion — is a common and costly error; TUPE has specific consultation and continuity requirements regardless of what the sale agreement states.
Choosing the structure on tax alone, without legal input. The tax treatment for buyer and seller genuinely differs between the two structures and is a real factor — but it is one factor among liability exposure, consent requirements and commercial continuity, decided with tax and legal advisers together, not by rule of thumb.

How the structure interacts with price and consideration

The structure and the consideration are usually negotiated together rather than in sequence. A buyer taking on more inherited risk in a share deal will often push for a larger retention, escrow or warranty period; a seller willing to give more extensive warranties may hold out for a cleaner cash price. Deferred consideration and earn-outs interact with the structure too — an earn-out tied to the performance of assets the buyer now runs directly, inside their own company, behaves differently from one tied to the performance of a subsidiary whose shares the buyer bought and whose management has stayed in place. LOI vs IOI covers where the structure is typically first signalled — in the non-binding heads of terms, well before the sale agreement is drafted — and getting that signal right early avoids a late renegotiation once due diligence has already been scoped around the wrong structure.

How TrueValue supports either structure

Whichever structure a deal ends up using, the work around it lives in the same record. The deal economics engine models the consideration however it is actually paid — cash at completion, deferred instalments, an earn-out with its own attainment assumption, a vendor note — and runs the funding, covenants and returns on that structure rather than a simplified stand-in. Due diligence request lists are built from templates a team can scope to what the deal actually needs, so a targeted asset-deal checklist and a comprehensive share-deal checklist are two different lists rather than one generic one force-fitted to both. And document generation drafts the offer document and its payment structure from the figures already on the deal, so the structure decided in the term sheet is the one that shows up in what gets sent.
