Dealmaking in Ireland in 2025 largely mirrored global M&A trends – the outlook coming into the year was hopeful, yet measured, with confidence stemming from the accelerated growth of the life sciences, technology and energy sectors and, in particular, the prospect of activity in the AI capabilities and technology space.
The impact of geopolitical events curtailed that expectation early on, with subdued levels of M&A activity in the first half of the year. Ultimately, however, the cautious optimism was not misplaced and activity rebounded in the latter half of 2025, resulting in a moderate increase in deal volume on a year-on-year basis.
Private equity activity grew by c. 20% in 2025. Strategic acquirers, however, continued to drive much of the activity, as companies focused on portfolio realignment - whether defensive or transformative - and scope-expanding deals.
