Based on share price performance, global dealmakers achieved a market outperformance, as companies making M&A deals outclassed the wider market by +2.5pp (percentage points) for acquisitions valued over
Jana Mercereau, Head of Europe M&A Consulting, WTW, said: “Mega transactions have re-emerged with a vengeance. Well-capitalised dealmakers have returned to the market with renewed confidence, taking advantage of improved M&A conditions to pursue large strategic transactions to scale operations, bridge capability gaps and secure critical AI-enabling technologies.”
European dealmakers led the M&A sector with a strong performance during the first quarter of 2026. Based on share price performance, European buyers outclassed companies not involved in M&A activities by an impressive +6.0pp (percentage points), with 40 completed deals. UK acquirers mirrored the wider European trend with a positive performance.
In contrast, Asia-Pacific buyers were -3.4pp below their regional index with 49 deals completed in the first quarter of 2026. With 21 transactions already closed in the first three months of 2026, Chinese buyers maintain their current form of increased deal activity following the record lows of 2024. North American acquirers also underperformed their index by -5.4pp, with 117 deals completed in the last three months, compared to -16.1pp and 96 deals in the final quarter of 2025.
Mercereau said: “Pent-up demand, a favourable regulatory environment and healthy balance sheets have reawakened animal spirits, driving the value of dealmaking close to all-time highs. The duration and scale of the Middle East conflict, however, risks denting deal momentum, with corporate executives likely to stretch timelines and deepen due diligence.
“Boardroom confidence remains strong, for the time being at least, as dealmakers normalise heightened geopolitical risk and appear resolved to ride through the bumps and persist with strategic deals.”
WTW QDPM Methodology
- All analysis is conducted from the perspective of the acquirer.
- Share-price performance within the quarterly study is measured as a percentage change in share price from six months prior to the announcement date to the end of the quarter.
- All deals where the acquirer owned less than
50% of the shares of the target after the acquisition were removed, hence no minority purchases have been considered. All deals where the acquirer held more than50% of target shares prior to the acquisition have been removed, hence no remaining purchases have been considered. - Only completed M&A deals with a value of at least
$100 million which meet the study criteria are included in this research. - Deal data sourced from LSEG.
