What High-Performing M&A Teams Do Differently And How to Replicate Their Success

Not all advisory M&A teams are created equal! Some consistently deliver deals, build client relationships, and attract top talent, while others struggle to maintain momentum. These differing fortunes are rarely solely led by a collective’s technical ability. High-performing teams approach their work in ways that create a competitive edge. Understanding these habits is key for firms that want to mirror their success.

These behaviours have become even more important as dealmaking across the United Kingdom and France faces cyclical pressure, with subdued volumes in 2023 followed by a cautious recovery through 2024 and into 2025. Rising interest rates, the disappearance of ‘cheap debt’, valuation gaps, and more regulatory scrutiny have forced teams to be more commercial and more adaptable than ever.

1. They Build Trust Through Consistency

In M&A, track record and delivery are everything. High-performing teams adhere to deadlines, produce quality work, and take their responsiveness seriously. This consistency builds trust with clients and colleagues alike, creating long-term relationships that lead to repeat business. Firms that are disciplined and plan resourcing set themselves up for better performance further down the line.

This has been particularly evident in the UK mid-market, where deal flow has remained relatively resilient despite macroeconomic headwinds. Clients are prioritising advisers who can execute with certainty in uncertain conditions despite longer deal cycles, rather than those chasing volume alone.

2. They Collaborate, Not Compete

While individual performance matters, the best teams know that advising is a team game. Knowledge is shared, juniors are exposed to client thinking, and client wins are treated as collective achievements. This culture of collaboration prevents burnout and helps firms scale. Leaders who reward team contribution as much as individual results via strong bonuses and high-quality deals model good behaviour that helps drive their team forward.

In France, where cross-border transactions account for a significant share of activity, collaboration has taken on added importance. Teams that integrate sector expertise, geographic insight, and varied regulatory knowledge are better positioned to win and execute complex international deals, often in collaboration with other country teams.

3. They Balance Execution With Perspective

High-performing teams don’t just complete tasks; they try to take a 30,000 ft view. Junior bankers are encouraged to think beyond spreadsheets, and seniors spend time translating numbers into strategy, marrying data with anecdotes and experience. This balance between flawless execution and commercial thinking allows teams to deliver real insight to clients, not just transactions.

As private equity firms in both the UK and France become more selective and focus on high-quality assets, operational value creation, and sector specialisation (notably in technology, healthcare, and energy transition), advisers who can connect analysis to strategy set themselves apart.

4. They Invest in Development Early

Future leaders are spotted early and given responsibility. Mentorship, client exposure, and stretch assignments are woven into team culture. Firms that prioritise development keep ambitious talent for longer and reduce the risk of losing them to direct competitors, although the pull of private equity remains strong for junior bankers, in particular.

This is especially relevant in today’s talent market. Both the UK and France have seen continued competition for experienced dealmakers, despite slower hiring cycles. Teams that create clear development pathways are better able to retain top performers and maintain continuity with clients. People like to do business with people they know, and talent that sticks around is key to that.

5. They Adapt Quickly to Market Shifts

M&A cycles are volatile. Top teams maintain momentum by reallocating resources, exploring new sectors, or adjusting client focus when conditions change, which is particularly relevant in today’s topsy-turvy geopolitical climate. This adaptability ensures they are positioned for growth, even in challenging markets.

Recent trends underline this point. In the UK, there has been a gradual rebound in sponsor-led deals and a renewed focus on domestic consolidation. In France, strategic buyers have remained active, especially in industrial and energy-related sectors, supported by government-backed investment initiatives and a strong emphasis on sustainability.

Conclusion

High-performing M&A teams succeed not because they work harder, but because they work smarter and incorporate AI into their work where possible. They champion trust, collaborate, maintain perspective, invest in people, and adapt quickly.

In a market environment like today’s — where dealmaking in the UK and France is stabilising but still selective — these qualities are no longer optional. They are what separate teams that wait for the market to recover from those that shape it. It all starts from the top.
