According to the latest Experian M&A report, Arthur Cox advised on 29 of the 391 deals which took place in the first six months of the year, ahead of A&L Goodbody and Regan Wall on 26 each.

Flynn O’Driscoll took fourth place with 25 deals, followed by Matheson on 20, Beauchamps on 16, both McCann FitzGerald and Eversheds Sutherland on 14, William Fry on 11 and Wallace Corporate Counsel on 10.

There were a total of 391 deals worth €28.7 billion in the first half of 2025, a 15 per cent decline in volume but a 27 per cent increase in value.

“The majority of deals were driven by domestic activity, but Ireland continued to attract strong international interest, particularly from UK and US acquirers,” the report states.

“Outbound investment also remained focused on these markets, with activity spanning a broad range of sectors including manufacturing, TMT, wholesale and retail, and financial services.

“High-value transactions gained momentum, with eight deals exceeding €1bn in value — up from just two in the same period last year.

“While the SME segment saw a slowdown, with smaller deals down 34 per cent and mid-market activity falling 41 per cent, corporate acquisitions remained the primary driver of deal flow, accounting for 69 per cent of all transactions.

“Venture capital and buy-out activity also remained robust, contributing a further 26 per cent to overall volume.”
