Transatlantic M&A delivers benefits beyond the deal

The research finds widespread economic benefits of transatlantic M&A. Nine in ten (91 per cent) decision-makers surveyed say current levels of large-cap ($1bn+) (€892m) (£746m) transatlantic M&A have a positive impact on their country’s economy.

At company level, 85 per cent of M&A decision-makers report increased revenues and 85 per cent improved productivity within 24 months of a transatlantic deal. The majority also report improvements in profitability (85 per cent), market share (83 per cent) and international expansion (83 per cent).

AI and infrastructure demand continue to shape acquisition strategy

The surge in AI investment is also expected to continue, with almost a third (31 per cent) of decision-makers reporting that AI and infrastructure demand is the single biggest factor expected to influence acquisition strategy in 2026-27.

The findings point to deal activity in 2026 being driven not only by the desire to access to new markets, but by the need to acquire technology, capabilities and infrastructure that can support future growth.

Deal appetite remains strong despite regulatory friction

The research also shows that M&A decision-makers are adapting to a more demanding regulatory environment. More than half (53 per cent) have modelled longer timelines or higher costs because of tighter foreign direct investment and national-security screening.

Almost half (45 per cent) are making greater use of joint ventures or minority investments, while 26 per cent have abandoned a deal before due diligence because of tighter screening.

Despite these challenges, 83 per cent of decision-makers expect large-cap transatlantic M&A activity to increase over the next 12 months.

Adam Griffiths, corporate partner and head of Winston Taylor Ireland, commented: “We are very encouraged by the positivity and confidence that global M&A decision makers have regarding transatlantic deals. Ireland has strong investment links with the US, UK and EU and is particularly impacted by the trends that we are seeing in global M&A. The continued appetite for cross-border deals has the potential to create real opportunities for Irish businesses.

“However, Ireland is competing for that investment. As transatlantic deal activity increases, maintaining a stable and competitive environment for international investment will be important if Ireland is to continue attracting capital and support businesses looking to invest, acquire and grow.”
