Domestic mergers and acquisitions

Mergers and acquisitions (M&A) of UK resident companies acquiring other UK resident companies.

Inward mergers and acquisitions

Mergers, acquisitions and disposals of UK resident companies by foreign companies.

Outward mergers and acquisitions

Mergers, acquisitions and disposals of foreign companies abroad by UK resident companies.

Mergers and acquisitions transactions

M&As occur when one company takes control of another company. The internationally agreed definition of an M&A deal is when one company gains more than 50% of the ordinary shares (or voting rights) of the acquired company.

Disinvestments (disposal transactions)

Disinvestment, or disposal transactions, refers to the disposal of the ordinary share ownership of a subsidiary company.

Since Quarter 1 (Jan to Mar) 2018, mergers and acquisitions (M&A) statistics fully incorporate the Bureau van Dijk (BVD) M&A, which has been renamed Moody's Orbis M&A, data source and methods. The introduction of this new data source increased the coverage of smaller M&A transactions and, therefore, resulted in a discontinuity in the number of transactions reported. Therefore, users are advised to take care when comparing recent estimates with the number of transactions reported for quarters before 2018.

The Russian invasion of Ukraine began on 24 February 2022 and in response, the UK government has imposed a range of economic sanctions on Russia from late February and early March 2022, as described in the Russia sanctions: guidance on GOV.UK. We will continue to monitor potential impact of the conflict and resulting sanctions in future quarterly releases.

More quality and methodology information on strengths, limitations, appropriate uses, and how the data were created is available in our Mergers and acquisitions Quality and Methodology Information (QMI).

About Office for National Statistics datasets

The datasets for mergers and acquisitions involving UK companies have recently been reviewed to ensure that they meet the accessibility standards outlined in the Government Statistical Service (GSS) guidance on releasing statistics in spreadsheets. This is to ensure that all GSS outputs meet Web Content Accessibility Guidelines, a legal requirement set out in The Public Sector Bodies (Websites and Mobile Applications) Accessibility Regulations 2018.

We welcome any feedback on these changes. Please share your feedback by emailing MA@ons.gov.uk.

Accredited official statistics

These accredited official statistics were independently reviewed by the Office for Statistics Regulation in June 2013. They comply with the standards of trustworthiness, quality and value in the Code of Practice for Statistics and should be labelled "accredited official statistics".

Strengths and limitations

We produce statistics on the number and value of mergers and acquisitions (M&A) transactions. This information is presented in the following way:

• transactions are only recorded in our statistics, once the deal has been legally completed each transaction has a value of at least £1 million.

• the transactions result in a change of ultimate control of the target company

• all values are in current prices and therefore have not been adjusted for the effects of inflation

These are among the main reasons our M&A statistics can differ from those reported in other sources. There can be a substantial time gap between the point at which a deal is announced and when it is legally completed. In addition, in some cases, announced M&A deals do not take place.

Our statistics on disposals (or de-mergers) are also included in tables alongside this bulletin. These are typically fewer in number per quarter, which can lead to greater suppression of statistics to mitigate disclosure. The focus of this bulletin is on acquisitions, although some of the more complex deals can include the disposal of some part of the newly created corporate structure.

It is sometimes necessary to suppress figures for certain items to avoid disclosing information about an individual business. Further information on why statistics are suppressed is available in our Disclosure Control Policy.

It is not uncommon for the value of M&A transactions to vary considerably from one quarter to the next. This mainly reflects the nature of M&A activity in that these capture one-off deals. Therefore, if a particularly high-value M&A deal completes in a given quarter, it can make that quarter seem out of line with those that precede and follow it.

The volatility of M&A transactions also makes it difficult to link M&A statistics with other economic indicators – such as gross domestic product – or global events because of the time it can take between announcing and completing a M&A deal. Therefore, it can be more informative to look at longer-term trends within M&A statistics, rather than focusing on quarterly movements.

Details of any notable M&A deals that were completed in Quarter 2 (Apr to Jun) 2026 can be found in Sections 3, 4 and 5 of this statistical bulletin. Lists of notable completed M&As valued above £100 million and which took place in earlier quarters, can also be found in previously published Mergers and Acquisitions quarterly bulletins.
