Where M&A Value Is Won or Lost: People

M&A activity is typically grounded in rigorous financial and operational due diligence. Revenue quality is assessed, cost synergies are modelled, legal and commercial risks are scrutinised, but what about the drivers of the business; the employees?

According to the Harvard Business Review, mismanaging people and failing to merge company cultures is the reason for two-thirds of failed transactions.

In many cases, value is lost in the weeks and months that follow rather than at the point of transaction. This is where people become disengaged, decisions slow and high performers leave.

The Early Signs of Value Leakage

In the immediate post-acquisition period, organisations often experience a subtle but measurable shift in performance.

Uncertainty is high and teams operate with greater caution.

In growth-stage businesses in particular, where speed and responsiveness are critical, this loss of momentum has a direct impact on performance.

The Underlying Cause

These issues are typically driven by uncertainty amongst the team.

Will the new management be making cuts? What's the strategy and direction? What will change for me and my role?

Uncertainty around decision-making authority, roles and expectations and how the organisation will operate going forward breeds disengagement.

In many mergers or acquisitions, these questions are left unresearched during due diligence, communication isn't clear or forthcoming when the deal is signed and questions are unresolved during the transaction process. It is assumed that clarity will emerge naturally once integration begins but that can have a significant impact on the business in the meantime.

What Traditional Due Diligence Misses

Financial due diligence provides a clear view of the business being acquired. However, it does not provide a clear view of how the people in the business actually operate on a day-to-day basis.

Where does the real decision-making authority sit? What is the culture actually like? Where leadership capability is strong or stretched? What is the retention rate?

These factors only become visible once the organisations begin to integrate and they can hold real monetary value if identified earlier to spot areas for growth or if you're purchasing a company with a team that is either underperforming or delivering at max capacity.

The Impact on Integration

When these dynamics are not understood early, integration becomes slower and less effective. Will the company culture that you are acquiring marry with the culture of the acquiring company?

Leadership teams may unintentionally create gaps in ownership causing key individuals to step back rather than step forward. This can lead to teams waiting for direction rather than act with confidence. Externally, this can begin to affect client experience.

Successful integrations tend to share a common characteristic. They create clarity early.

The announcement to stakeholders (the employees in both companies, customers, suppliers and the general public) is crucial in the timing, channel and context of how it is handled.

This enables teams to maintain momentum and confidence during a period that would otherwise introduce friction.

The First 90 Days

Once the deal is completed and announced, the initial post-acquisition period is critical.

This is when employees are forming their understanding of the new organisation, leadership behaviours are most closely observed and confidence in the future vision is either reinforced or undermined.

Organisations that establish alignment and clarity during this period tend to stabilise quicker and realise value sooner.

While M&A transactions are often viewed primarily as financial events, in practice, they represent significant organisational change at scale.

Value is ultimately realised through people. Understanding how they operate, how they make decisions and how they respond to change is critical.

Without that understanding, even well-structured deals can lose momentum and once momentum is lost, it is significantly harder to regain.
