Global rebound in M&A activity sets stage for busy final quarter

October 9, 2023

Mergers and Acquisitions
  • All regions see an upswing in deal activity as global M&A increases by 16% with 151 deals closed in the last three months compared to the previous quarter (130 deals).
  • The steady decline of large deals continues with 32 transactions completed during July to September 2023 compared to 50 deals for the same quarter in 2022.
  • Deal makers have their worst quarterly performance since the launch of WTW’s M&A Index in 2008.

LONDON, October 9, 2023 — Global mergers and acquisitions (M&A) activity increased in the third quarter of this year, according to research on completed deals from WTW’s Quarterly Deal Performance Monitor (QDPM). Global volume rose by 16% with 151 deals over $100 million in value completed during July to September, making it the busiest quarter of the year so far [1].

Despite this latest upswing in deal activity, large deals (valued over $1 billion) have continued to see a steady decline in volume that began in 2021 with 32 deals closed during July to September 2023. For the same quarters in 2022 and 2021, 50 and 67 large deals were completed, respectively.

Jana Mercereau, Head of Corporate M&A Consulting, Great Britain at WTW, said: “Rising interest rates translating to higher financing costs, increased antitrust scrutiny and a more cautious attitude from lenders have been driving the sluggish pace of bigger, more complex deals.

While it is too early to call a comeback, the recent rebound in deal volume across regions indicates pent-up demand,”

“While it is too early to call a comeback, the recent rebound in deal volume across regions indicates pent-up demand, with M&A activity anticipated to improve as deal makers enter the final and busiest quarter of the year.”

Run in partnership with the M&A Research Centre at The Bayes Business School, the WTW data reveals macroeconomic pressures have taken their toll on deal performance. Based on share price performance, buyers underperformed the wider market by -8.7pp (percentage points) for deals completed between July and September 2023. This is the worst quarterly performance since this study began in 2008.

The M&A data shows that Asia Pacific continues to be the only region to outperform its regional index. For the ninth consecutive quarter, buyers in the region outclassed their index with a positive performance of +7.6pp, with 35 deals closed in Q3 2023. This also represents an increase of five deals compared to the previous quarter.

Acquirers from both North American and Europe saw a similar increase in deal activity. North America buyers completed 77 deals during July to September this year, which is a 12% increase compared to the second quarter. Meanwhile, buyers from Europe completed 32 deals in the last quarter, up from both Q1 and Q2 2023. In contrast to the Asia Pacific region, however, acquirers in North America and Europe underperformed their regional indices by -10.3pp and -3.4pp respectively.

With the exception of the Energy/Power and Industrials sectors, where M&A deals recorded a marginally positive performance of +1.5pp and +1.9pp respectively compared to non-acquirers in their markets for the year to date, all other industries including High Technology (-18.5pp) and Financial Services (-7.2pp) have underperformed.

Mercereau said: “There is almost no margin of error in M&A deals today. With M&A activity widely expected to pick up pace, companies need to be ready to identify the right targets, how they fit in their business, navigate accelerated due diligence processes driven by aggressive timelines, and above all ensure the right people are integrated to maximise M&A value.”

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 than 50% 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 Refinitiv.
