When ownership changes: what happens to people and why it determines deal value
For those signing the deal, an acquisition is a transaction. For the people inside the business, it is the day their leadership, rules, and certainties change all at once.
And the one question that ultimately determines the outcome—yet is rarely asked before signing—is this: how will people respond?
A transaction, seen from the inside.
In the weeks following the announcement, something happens inside an acquired company that no spreadsheet can capture:
- Key employees begin asking themselves whether to stay or explore new opportunities.
- Managers wonder whether they will be able to lead in an environment they do not yet understand.
- Teams watch for the first signals to understand whether the new ownership will value them—or leave them behind.
- These are deeply human reactions, and precisely because they are human, they are inevitable, even if their consequences remain difficult to predict. Yet this is where planned synergies, customer retention, and the speed at which the new organization regains momentum are truly decided.
To a large extent, this is where the real value of an acquisition is won—or lost.
The only "living" asset that is rarely assessed.
Almost every aspect of a company is thoroughly examined: financial statements, contracts, inventory, litigation. Financial, legal, and commercial due diligence are exercises in precision. Yet the one living dimension—the people—is still too often assessed through intuition because it seems impossible to measure.
Ironically, this is exactly where many deals fail. In a McKinsey survey of nearly 1,100 M&A executives, 44% identified poor cultural compatibility and friction between the two organizations as one of the leading reasons why integrations fail to deliver on expectations (McKinsey, The Culture Compass).
When acquisitions disappoint, they most often disappoint for human reasons.
Five factors that determine whether people adapt or resist.
The way people respond to a change in ownership consistently revolves around five key dimensions. They are worth considering for what they truly are: human experiences before they become business risks.
- Culture: feeling at home—or like an outsider.
When two organizations differ in the way they make decisions, communicate, and work, people become cautious, collaboration slows, and expected synergies remain little more than projections (read more here: Culture as a business risk: when two organisations don't speak the same language). - Key people: those who hold the knowledge that exists nowhere else.
In many organizations—particularly family-owned businesses—critical expertise, customer relationships, and operational know-how reside with just a handful of individuals. When they leave, part of what was acquired leaves with them. According to Gallup, replacing an employee typically costs between one-half and two times their annual salary (Gallup, The Great Discontent), even before accounting for the institutional knowledge that disappears with them (read more here: Key People: how not to lose the value you paid for) - Leadership: who people are truly willing to follow.
Beyond the organizational chart, what matters is identifying those with the credibility to lead the business through uncertainty and sustain performance during the critical first months. - Readiness for change: who embraces the future—and who waits for it to pass.
An organization can either make the new direction its own or quietly resist it. The difference determines whether the business plan becomes reality or remains simply a document. - Measurability: what can be understood can be managed.
All these dimensions have one thing in common: they can be observed, assessed, and benchmarked through a structured methodology, replacing assumptions with actionable insight.
The right time to assess people.
The instinct is to focus on people once the transaction is complete—when the problems have already surfaced. The organizations that create the greatest value assess people before then.
The approach depends on the stage of the transaction:
-
During pre-signing, while the transaction remains confidential, the assessment is conducted at an aggregated and anonymous level, providing insight into culture, organizational climate, and resilience without exposing either the deal or individual employees.
-
During pre-closing, once the transaction has been announced, the organizational assessment is complemented by targeted evaluations of key individuals to identify those who will truly lead the next chapter.
The evidence clearly favors those who act early.
McKinsey recommends defining clear, objective people-related criteria from the outset rather than relying on intuition (McKinsey, Why Managing Culture Is Critical for Value Creation in M&A) and shows that organizations that effectively manage cultural integration are more than 40% more likely to achieve cost synergies and up to 70% more likely to realize revenue synergies.
What appears unpredictable can, in fact, be understood. And what can be understood can be managed.
Changing the perspective before changing the tools.
Managing the human factor does not begin with adopting a new tool. It begins by treating people as a value driver, with the same rigor applied to financial metrics.
This applies to the business owner seeking to protect the value built over years, to the acquirer pursuing sustainable synergies, and to the advisors whose reputation ultimately depends on transactions that continue to perform long after the deal is signed.
This is the perspective from which ASAP Italia supports organizations navigating change: understanding the unique people-related risks within every business and transforming them into lasting value.
