Disclosure of inside information – FCA Primary Market Bulletin on leaking inside information during M&A
The Financial Conduct Authority (FCA) has published a Primary Market Bulletin (PMB 54) which focuses on strategic leaks during M&A transactions and the fact that a leak may involve the unlawful disclosure of inside information.
The FCA says that it has seen an increase in situations where material information on live M&A transactions appears to have been deliberately leaked to the press. Examples of the information leaked include details of discussions between the board of a target company and a potential bidder following an approach about a possible takeover offer, or where the target board has rejected an approach but an increased offer is likely.
It notes that the leak of inside information may be inadvertent, by hinting at market sensitive information even if specific details are not mentioned, or strategic, where the information is deliberately given to the press by individuals at an issuer or its advisers. The FCA is concerned that there is a culture among market participants that strategically leaking inside information to the media is acceptable during a transaction.
The FCA reminds parties that the information being leaked is often inside information under the UK Market Abuse Regulation (UK MAR) and that UK MAR prohibits the unlawful disclosure of inside information. Unlawful disclosure is where a person possesses inside information and discloses that information to any other person, “except where the disclosure is made in the normal exercise of an employment, a profession or duties”.
The FCA warns individuals directly involved in transactions that:
It also reminds issuers and their advisers that:

M&A – our sector and broader perspectives for 2025
In our global M&A report for 2025, ‘Gaining Altitude’, we forecast deal activity increasing throughout the year, but with the hard work which characterised so many deals in 2024 likely to continue.
We also explored:
We also shared regional perspectives from our teams around the world, in which we looked at regional trends in M&A and the outlook for 2025.
We have now published our sector and broader perspectives in which we look at sectoral and wider trends in M&A.
March has been the strongest month for public M&A activity in 2025 so far, matching the number of firm offers seen in March 2024 with seven. There has been a significant uptick in possible offers compared to previous years, with a further 12 announced (compared to six in 2024). Activity levels for 2025 so far are similar to 2024, with 12 firm offers in 2025, compared to 13 in 2024 at the same stage.
Eight of the firm offers announced in 2025 so far have had a value under £250 million and only one has been valued over £1 billion. This is in contrast to the trend we saw in 2024, where the number of high value deals rose significantly. March saw six out of the seven firm offers being valued under £250 million, including Xtellus Capital Partners' offer for Serinus Energy plc valued at £5.1 million and Kondor AI PLC's offer for Ora Technology plc for £20.5 million. The average deal value for 2025 so far is dwarfed by 2024, standing at £263 million compared to £977 million and lags behind 2023 which averaged £362 million. There is still a long way to go in 2025, and there are large deals in the pipeline such as Greencore Group plc's possible offer for Bakkavor Group plc valued at £1.14 billion.
