Buy and build remains the dominant value creation strategy across European private equity. Deal volumes may flex with rates and macro conditions, but the underlying logic — acquire a platform, bolt on complementary businesses, and exit a significantly larger, more valuable entity — has proven durable across market cycles. For mid-market sponsors in particular, it is often the clearest route to a premium exit multiple.

Yet failure rates remain stubbornly high. Research consistently suggests that more than half of M&A integrations underdeliver against their original thesis. In a buy and build context — where you may be executing multiple acquisitions across different geographies, cultures and management teams simultaneously — the risks compound quickly.

The pattern we see most often in European portfolios is not a failure of strategy or deal origination. It is a failure of execution. And execution risk, in the context of buy and build, is fundamentally a leadership risk.

The execution gap

Most buy and build programmes are designed with significant rigour at the front end. The investment thesis is well-constructed. The pipeline of targets is credible. The synergy case is detailed. Where things go wrong is in the translation of that plan into operational reality — and that translation depends almost entirely on the people leading it.

The platform CEO is often the first point of failure. Buy and build requires a very specific leadership profile: someone who has managed acquisitive growth before, who understands the integration playbook, who can hold the confidence of a demanding sponsor while simultaneously managing the cultural sensitivity of bringing new businesses into the fold. A CEO who has only grown organically will find the pace and complexity of a multi-acquisition programme genuinely difficult to navigate.

The COO is the second. In European buy and build, where acquisitions frequently span country borders and involve businesses with distinct operating models, the integration function cannot sit with the CEO alone. A dedicated operational leader — one who has run post-merger processes before — is often the difference between synergies being realised on schedule and the business spending eighteen months firefighting instead.

The CFO is the third. Managing the financial complexity of a multi-entity, multi-jurisdiction business — consolidating accounts, maintaining covenant headroom, managing earnout structures and providing credible reporting to the board — requires a finance leader who has been through this before. A CFO who has only ever managed a single-entity P&L will be stretched.

The European dimension

Buy and build in Europe carries specific complexities that pan-US programmes do not face to the same degree. Language, employment law, cultural attitudes to management authority, and the variation in how businesses operate across Northern, Central and Southern Europe all create friction in integration processes that are already demanding.

Sponsors running pan-European buy and build programmes increasingly recognise that they need leaders who have managed across geographies — not just executives who have operated in one market and are being asked to expand. The ability to build trust quickly with management teams in different countries, to navigate different labour market norms, and to maintain a coherent culture across a growing and geographically dispersed business is a genuine capability, not a given.

We see this most acutely at CEO level. The executives who succeed in European buy and build tend to have personal experience of operating in at least two markets, a track record of M&A integration (not just deal origination), and the interpersonal range to operate across cultural contexts without defaulting to a single leadership style.

What sponsors get right — and wrong

The sponsors who execute European buy and build most effectively share a common characteristic: they invest in leadership before they need it. The CEO search happens before the first add-on, not after the second acquisition has already created integration problems. The COO is in place when the third deal completes, not brought in to resolve the chaos that follows.

The sponsors who struggle tend to underestimate how quickly the leadership demands of the platform change as acquisitions accumulate. A management team that was more than adequate for a £30m business running a single geography can be genuinely out of depth once the platform has reached £100m across three countries. The gap between what the business needs and what the team can deliver opens slowly at first, then very quickly.

By the time the gap is obvious, the cost of addressing it — in lost momentum, management distraction, and erosion of sponsor-management trust — is already significant. The answer is almost always the same: earlier, more deliberate leadership investment at the point where the programme is designed, not after it has begun to show strain.

The talent dimension

Experienced buy-and-build operators are a genuinely scarce resource in European private equity. The executives who have run multi-acquisition programmes across multiple geographies, who understand the cadence of a PE hold period, and who can manage both the integration complexity and the sponsor relationship simultaneously are a finite pool. They are almost never on the open market. Reaching them requires genuine relationships, not a LinkedIn search.

At HMN Capital, we work with sponsors and portfolio businesses planning or executing buy and build programmes across the UK, Europe and the Middle East. Whether the need is a platform CEO who can lead an acquisitive growth strategy, a COO to own integration, or a CFO to manage the financial complexity of a multi-entity structure, we understand what the role demands and where to find the people who can do it.
