Read the report directly on the Datasite site here.

As Q3 2025 unfolded, the global M&A landscape showed a steady footing in some regions and deceleration in others. Trade dynamics, valuation discipline, evolving monetary policy, and sector-specific shifts shaped the way dealmakers approached transactions across APAC, EMEA, and the Americas.

The latest Deal Drivers reports, published by Datasite and Mergermarket, present a regional view of how each market performed in the third quarter and identified trends that will influence dealmaking in the last quarter of the year.

Key Takeaways

• Global M&A Q3 2025 trends: Diverging momentum across APAC, EMEA, and the Americas as dealmakers adapt to shifting macro conditions.
• APAC M&A slowdown: Q3 deal value fell to US$215bn (−27.7% quarter-on-quarter), with Greater China leading pipelines and India/Southeast Asia sustaining growth.
• EMEA large-cap focus: Despite a 23.4% year-on-year volume drop, aggregate value surged 41.6% to €307.1bn, driven by strategic repositioning and energy transition.
• Americas record deal value: Q3 hit US$817bn (+51.6% year-on-year) amid declining volumes, fueled by TMT, AI infrastructure, and recurring-revenue assets.

APAC: China dominant, India, Southeast Asia show steady deals

APAC entered Q3 on steadier ground following the tariff swings earlier in the year. India remained the region’s bright spot with one of the strongest growth profiles globally, while Southeast Asia benefited from ongoing supply-chain reconfiguration and logistics tailwinds.

Greater China led APAC’s forward pipeline with 568 ‘for sale’ stories, heavily weighted toward industrials & chemicals (I&C), technology, media, and telecoms (TMT), and pharma, medical, & biotech (PMB). China continued to localize semiconductor inputs and showed readiness to scrutinize even foreign-to-foreign deals touching its market.

Southeast Asia and India remained central to the region’s structural growth story, with diversified opportunities spanning manufacturing, digital connectivity, renewable energy, and financial services. Australia & New Zealand also contributed a balanced pipeline, supported by activity in critical minerals, PMB, and TMT.

After a blistering H1, APAC’s M&A market lost a step in Q3. Deal value dropped to US$215bn, down 27.7% from Q2 and 9.2% year-on-year, while volume slipped 12.2% to 2,462 deals. The decline followed two quarters of exceptionally strong big-ticket activity as buyers paused to digest transactions and reassess valuations.

EMEA: Lower volumes but concentrated large-cap deals

In EMEA, macroeconomic conditions were mixed but manageable. The European Central Bank held rates steady as inflation neared target and the euro-area GDP growth outlook improved. External risks—particularly the return of US–China trade friction—tempered sentiment, while policymakers pushed to fast-track revisions to EU Merger Guidelines, emphasizing innovation effects and scrutiny of below-threshold deals.

Mergermarket’s heat chart positioned DACH as the hottest near-term opportunity set, with notable concentration in TMT and I&C. Sectoral transitions—particularly energy, renewables, and data infrastructure—continued to anchor deal pipelines, even as mid-market buyers grew more selective.

EMEA recorded 3,711 deals in Q3, down 23.4% year-on-year, marking one of the sharpest volume contractions in recent years. Yet aggregate value rose 41.6% year-on-year to €307.1bn, reflecting a concentration of large-cap transactions and continued strategic repositioning.

Americas: Surging value amid decline in volume

The US began Q3 with monetary easing back on the table as the Federal Reserve cut rates again in September. Inflation had cooled but remained above target, and softer labor data alongside moderating consumption prompted action. The broader macro picture pointed to deceleration rather than distress.

Elsewhere in the region, Brazil faced “stagflationary” pressures, while Mexico’s earlier resilience began to fade. Momentum across the Americas slowed through Q3, with M&A becoming increasingly top-heavy.

TMT was the most active sector for ‘companies for sale,’ with 589 stories, reinforced by “buy over build” strategies across AI infrastructure, semiconductors, and cloud software. Strategic bidders and private equity both showed interest in recurring-revenue assets and technology platforms, though valuations remained high.

The Americas saw the sharpest disconnect between volume and value in more than three years. Q3 recorded just 3,235 deals—down 14.6% year-on-year and the lowest in years—yet aggregate value surged 51.6% to US$817bn, the highest level in four years.

Sustaining momentum: Key factors for year-end and beyond

Across APAC, EMEA, and the Americas, Q3 revealed a common theme: dealmaking concentrated around scale, resilience, and strategic clarity.

As monetary conditions evolve and geopolitical risks persist, the year-end trajectory will depend on whether strategic conviction, not just cheaper capital, is enough to sustain deal momentum into 2026.
