Irish M&A activity up 4% in first half of 2025 despite global challenges 

Some 236 deals were announced in the first six months of 2025, a new report from William Fry shows 

Mid-market size deals continue to dominate, with 88% of disclosed deal values ranging between €5m and €250m, the report found.

Irish merger and acquisition (M&A) activity has remained durable despite global challenges, a new report from law firm William Fry has found, with a total of 236 deals being announced in the first six months of 2025. 

It marks a 4% rise in transaction volume compared to the same period in 2024, while total deal value fell to €8.8bn, which reflected a more than 50% decline year-on-year. The law firm said this was underpinned by a slowdown in large-cap and transformational transactions.
