Asset purchase or share purchase

An asset purchase acquires specified business assets and agreed obligations. A share purchase acquires ownership of the company, which generally continues to hold its assets and liabilities. Neither structure is automatically best: assess the actual business, risks and tax consequences before agreeing the deal.

Identify what the buyer needs to operate and what the seller intends to retain. Compare employee, property, contract and licence implications. An asset purchase does not guarantee that every liability is excluded, and a share purchase does not eliminate consent or due diligence requirements.

Compare what changes hands and what stays behind

For an asset purchase, prepare a schedule of the assets and agreed obligations that the buyer needs to operate. Include stock, equipment, contracts, intellectual property, records and premises rights where relevant. Identify exclusions explicitly. A broad description of the business can leave uncertainty about a domain name, customer deposit or item of leased equipment that both sides assumed the other had addressed.

For a share purchase, investigate the company whose shares are being acquired. It normally remains the legal holder of its assets and obligations, so historic liabilities and contractual restrictions remain material to the buyer's review. GOV.UK distinguishes the responsibilities arising from sale of an entire shareholding and sale of part of a company's business. ^[1] Do not compare the two structures using headline tax rates alone.

Test continuity for customers, staff and property

Identify the agreements needed on the first day after completion. In an asset purchase, assignment or novation questions may arise; in a share purchase, change-of-control provisions may still matter. Ask who must consent and what happens if consent is delayed or refused. A purchase agreement between buyer and seller does not force an unrelated supplier, customer or landlord to accept the intended arrangement.

Map the legal employer before and after the proposed transaction and obtain an assessment of employee transfer obligations. The structure's label does not settle every TUPE question. Review premises occupation, operational licences and regulatory approvals separately. Use Employees when a business changes hands for employee planning and Contracts that need consent on a business sale for third-party consents so the structure comparison reflects the actual continuity requirements rather than only the document title.

Model the full financial position

Prepare comparable figures for the price, debt, working capital, tax, transaction costs and funds needed immediately after completion. In an asset deal, consider how individual assets and obligations are treated and whether additional financing is needed to run the acquired operation. In a share deal, examine cash, debt and other balances within the company. State assumptions clearly so the two models measure the same commercial outcome.

Ask tax and financial advisers to assess the actual parties, assets and proposed payments. Do not assume an asset purchase is universally tax-efficient for the buyer or that a share sale always produces a particular relief for the seller. Timing, ownership history and the form of consideration can matter. A structure that maximises one party's apparent tax advantage may create costs or continuity risks elsewhere in the transaction.

Allocate discovered risks to specific decisions

List material findings and decide whether each calls for further investigation, a condition, a price adjustment, a specific contractual protection or withdrawal. An asset purchase is not a guarantee that every liability is excluded, and a share purchase does not mean the buyer must accept every identified risk without negotiation. The contract should reflect the agreed allocation and the practical ability to recover if a protection is triggered.

Check the seller's retained assets and future plans. If a company owns both the trading operation and an unrelated investment, restructuring may be proposed before sale. Obtain advice before moving assets or making distributions. Those preparatory steps can create their own tax, creditor and contractual consequences and should not be treated as a simple administrative clean-up to fit a preferred deal structure.

For Business purchase due diligence support, bring both parties' objectives, an ownership chart and an initial asset, liability and consent list. Request a comparison tied to the business's actual operating needs. Record the chosen structure and unresolved conditions before detailed drafting proceeds. Revisit the decision if due diligence reveals a fundamental issue, such as a non-transferable licence or an unexpected historic liability that changes the original commercial assumptions.

Test the structure against one essential relationship

Select the customer, licence or supplier arrangement without which the acquisition would lose much of its value. Compare what happens to that relationship under each proposed structure. Identify the contracting entity, any relevant consent provision and the practical work needed to maintain service from completion.

Then include the associated cost and uncertainty in the transaction comparison. A structure that appears simpler on a tax or headline-price calculation may create a difficult operational dependency. Ask the legal and financial advisers to reconcile their assumptions before the parties commit to detailed drafting. The decision record should show which dependencies have been resolved, which remain conditional and who bears the consequence if they cannot be secured.

Illustrative scenario

A buyer wants a trading operation but not a separate property investment held by the company. The parties compare an asset transaction with possible restructuring before a share sale. Advisers assess the legal, tax and timing consequences rather than choosing a structure solely from the headline purchase price.

Preparation checklist

• List the required business assets and intended exclusions.
• Map liabilities and third party relationships.
• Compare consent, employee and premises requirements.
• Obtain coordinated legal and tax advice on the structure.
