We conducted 16 interviews with leaders from family businesses, private equity,
industrial companies and M&A advisory firms. The interviewees came from twelve organisations in Germany, Austria and Switzerland. They included supervisory board members,
Managing directors, board members and M&A professionals. The aim was to understand the significance of culture in the context of Mergers & Acquisitions (M&A) from the perspective of real-world decision-makers and practitioners.
The conversations were not based on a romanticised view of culture, but on the question of where culture actually has an impact in the M&A context: in decision-making, post-merger integration, leadership, value realisation and the handling of tensions. Five overarching insights emerged from the conversations.
The first key finding is clear: alongside strategy, cultural integration is one of the top three success factors. Culture has its greatest impact in the post-deal phase. This is where it becomes clear whether strategic synergies materialise, people stay, leadership is effective—or value is destroyed. Culture is therefore not a “soft factor”, but a force with tangible consequences for value creation, leadership and integration.
A second observation recurs in almost every conversation: managing directors, business owners and private equity (PE) representatives do not want rhetoric about measures; they want a precise picture of the cultural landscape. Not training, not a change programme, but a clear assessment of the starting point that can inform decisions and management. From this perspective, cultural work must be relevant to the business, objective and commercially grounded.
The third key finding deliberately places responsibility at the top: supervisory bodies and shareholders do not want to shape culture operationally—but they do want to understand where tensions exist, trust is lacking or integration could fail. Clarity about culture and giving it the right priority thus become strategic levers for effective oversight and trust.
The fourth pattern concerns not only the subject, but also the person presenting it: culture is taken seriously only when it is addressed with substance, a focus on outcomes and commercial clarity. Consultant-speak without experience of responsibility does not help. Instead, the conversations emphasise the value of a “navigator”: someone with business experience who gets to the point, without esotericism or change jargon.
The fifth key finding is also the most constructive: what matters is not making everything the same, but understanding cultural areas of tension. Respondents repeatedly affirmed the idea of a cultural assessment—supplemented by a Culture Risk Index—as a strategic compass for identifying risks, safeguarding trust and managing integration intelligently.
The interviews were also supplemented with quantitative assessments and consolidated on a
consolidated on a four-point scale, deliberately without a midpoint. The picture is clear:
| Hypothesis | Mean score | Finding |
|---|---|---|
| H1 Culture is a strategically relevant factor in the pre-deal phase. | 3.14 | Agreement, with some differentiation. Less relevant for private equity (PE), but significantly more relevant for family-owned businesses and strategic buyers. |
| H2 Culture is highly relevant to the success of post-merger integration. | 3.93 | Clearly the highest rating. In the post-deal phase, culture is a critical success factor—especially in buy-and-build strategies. |
| H3 Cultural misalignment leads to value destruction. | 3.86 | Strong agreement. Risks include losing key people, tacit knowledge and skills, and established structures of trust. |
| H4 Cultural compatibility accelerates time to value. | 3.21 | Agreement, subject to certain conditions. When cultural alignment is achieved, the pace of integration and strategy execution increases significantly. |
1 = strongly disagree, 2 = somewhat disagree, 3 = somewhat agree, 4 = strongly agree
Separately from the interviews, we examined which success factors generally play a proven role in M&A transactions in Europe, regardless of culture. The analysis draws on meta-studies and industry research and identifies the following six TOP factors:
The subsequent academic analysis describes three cultural levers that have a particularly frequent and significant influence on these success factors in Post-Merger Integration (PMI):
Impact: Companies or cultures that can tolerate contradictions (e.g. centralized vs. decentralized, fast vs. careful) can shape speed better and avoid pseudo-harmony.
Example: Shared principles replace empty phrases and provide confidence to act.
Impact: Increases the “speed of error reporting”, willingness to experiment and problem-solving across units.
Example: Open Q&A formats (“Ask me anything”) and joint retros help during escalation periods in critical workstreams.
Impact: Lower power distance makes decentralized decisions and cross-team coordination easier; high power distance requires clearer formal governance.
Example: In Absorption , a strict RACI/RAPID logic works well; in Symbiosis , more co-design and learning spaces are needed.
These success factors make one thing clear: cultural compatibility, leadership dynamics and trust are not “soft” factors on the sidelines; they form the structural foundation for successful transitions. When people feel seen, their dignity is respected and new leadership acts with care, a shared future can take shape. A cultural landscape assessment is therefore not an add-on, but a tool for steering strategic integration.
reality. That is precisely where the strategic value of a cultural landscape assessment lies: not as an add-on, but as a tool for steering strategic integration.
In this view, culture is like a current beneath the keel. It determines whether a course holds, manoeuvres succeed and teams reach port safely. Without a cultural landscape assessment, PMI plans seem plausible—until they meet reality. That is precisely where the strategic value of a cultural landscape assessment lies: not as an add-on, but as a tool for steering strategic integration.
Company culture can rarely be captured in a single article. If you would like to share your perspective or discuss a question, we would welcome your thoughts.
If you would like to apply this question to your own company, schedule a no-obligation Compass Conversation. Together, we can assess which cultural opportunities or risks are relevant to your situation.
If you are working on a new or current integration, the Culture Risk Screening gives you an initial assessment of how well strategy and company culture align—as a starting point for a deeper review.
