In the UK, mergers and acquisitions (M&A) describe transactions in which one business acquires another, whether by purchasing the shares in a company or buying its business and assets. UK M&A activity spans everything from owner-managed company sales to complex cross-border deals involving regulated sectors, pension liabilities and national security considerations. While the commercial drivers vary, most transactions follow a familiar pattern: agreeing headline terms, carrying out due diligence, negotiating the sale agreement and ancillary documents, obtaining any required approvals, and completing (and often integrating) the target business.
What is the difference between share sales and asset sales?
A share sale involves the buyer acquiring the shares in the target company from its shareholders. The target company continues to own its assets and remains party to its contracts; the buyer effectively steps into the shoes of the shareholders and takes control of the company as a going concern. Share sales are common where the business is operated through a single company with established contracts, licences, employees and trading history. They can be attractive because, in many cases, contracts and permits remain in place without needing to be transferred. However, the buyer also inherits the company’s historic liabilities—known and unknown—subject to any protections negotiated in the sale agreement.
An asset sale involves the buyer purchasing specified assets (and sometimes assuming specified liabilities) from the seller. This can be structured to “cherry-pick” what is being acquired: for example, plant and machinery, intellectual property, stock, customer contracts and goodwill, while leaving behind unwanted liabilities. Asset sales can be useful where the seller’s corporate structure is complex, where only part of a business is being sold, or where the buyer wants to ring-fence risk. The trade-off is complexity: assets must be identified and transferred, contracts may require third-party consent to assignment or novation, and employees may transfer under the TUPE regime (which can impose obligations and restrict changes to terms). Tax outcomes also differ: for instance, stamp duty is typically payable on share transfers (at 0.5% on consideration for shares), whereas asset transfers may trigger different taxes depending on what is being sold (including VAT considerations and stamp duty land tax if property is involved).
What is the purpose and scope of due diligence?
Due diligence is the buyer’s investigation of the target business to understand what it is buying, validate the value proposition, and identify risks that should affect price, structure, contractual protections or the decision to proceed. It also helps the buyer plan integration and post-completion priorities.
In a UK M&A context, due diligence commonly covers:
- Corporate: ownership of shares, group structure, constitutional documents, shareholder arrangements, and authority to sell.
- Financial and tax: quality of earnings, working capital, debt, cash, tax compliance and historic issues.
- Commercial: key customers and suppliers, contract terms (change of control, termination, exclusivity), pipeline, and concentration risk.
- Employment: workforce terms, incentives, pensions (including defined benefit schemes), disputes, and TUPE implications.
- Real estate: title, leases, rent review provisions, dilapidations, and planning matters.
- Intellectual property and IT: ownership and licensing of IP, software arrangements, data security, and technology dependencies.
- Regulatory and compliance: sector-specific licences, anti-bribery and corruption controls, sanctions, competition law, and modern slavery compliance.
- Disputes and insurance: litigation, claims history, coverage gaps, and policy terms.
- Data protection: UK GDPR compliance, international transfers, and incident history.
- Environmental: contamination risk, permits, and legacy liabilities.
Findings from due diligence typically feed into the warranties and indemnities in the sale agreement, formal disclosure by the seller, and sometimes the use of warranty and indemnity insurance.
Why do overseas buyers purchase UK businesses?
Overseas buyers are often attracted to UK targets for several reasons. The UK offers a large, sophisticated consumer and business market, a respected legal system, and deep pools of talent in sectors such as financial services, technology, life sciences, advanced manufacturing and professional services. Acquiring a UK business can provide a platform for European or global expansion, access to established brands and customer relationships, and the ability to acquire proven management teams and operational capability rather than building from scratch. Currency movements can also make UK assets appear comparatively good value, and the UK’s time zone and connectivity can suit international operating models.
Are there common pitfalls for overseas buyers?
Cross-border buyers can encounter avoidable issues if they underestimate UK-specific legal and commercial features. Common pitfalls include:
- Underestimating employment and TUPE risk, particularly in asset deals, and not expecting the level of employee protection.
- Regulatory approvals and national security screening, including the UK’s National Security and Investment regime for sensitive sectors.
- Contract change-of-control and consent requirements, which can delay completion or weaken the acquired revenue base.
- Tax and structuring missteps, including VAT treatment, permanent establishment concerns, and post-acquisition integration planning.
- Cultural and governance differences, such as expectations around board processes, stakeholder engagement and disclosure.
- Overreliance on headline financials, without sufficient focus on working capital dynamics, customer concentration, or recurring revenue quality.
- Integration planning left too late, leading to loss of key staff, customer churn, or failure to realise synergies.
A well-run UK M&A process anticipates these issues early. Clear deal structuring, disciplined due diligence, and carefully negotiated contractual protections are central to achieving value and avoiding surprises—particularly for overseas buyers navigating an unfamiliar legal and regulatory landscape.
