236 mergers and acquisitions were carried out between January and June, up 4% on the same period last year.
However, deal value dropped 51% to a total of €8.8bn.
The latest report by William Fry reveals that mid-market size deals continue to dominate the market, with 88% of disclosed deal values ranging between €5m and €250m.
Five deals of €500m or more were recorded, matching the figures from the first half of last year.
63% of Irish deals involved overseas bidders, up from 57% during the same period last year, with strong activity from the US, UK and Norway.
Meanwhile, private equity accounted for 24% of Irish deals, with deal volume up 39% year-on-year; however, aggregate value of those deals fell 71%.
“Irish M&A activity remains resilient despite global challenges, with a modest increase in deal volume in H1 2025,” said Andrew McIntyre, Head of Corporate/M&A at William Fry.
“While deal values moderated due to fewer large transactions, the data highlights the strength of Irish assets.
“International interest is strong, and private equity is showing renewed momentum in the mid-market.
“Overall, these trends suggest Ireland is well-positioned for continued dealmaking in H2,” he added.
