Mergers and acquisitions often look perfect on paper, with strong financials, market share, and growth potential. Yet, a surprising number fail to deliver expected value.
The missing piece is rarely strategy or operations, it is the human side of the deal.
Differences in company culture, weak change resilience, and gaps in human connection can quietly derail even the most promising mergers. Understanding and measuring these human risks before the deal is signed is no longer optional; it is essential for integration success and long-term value creation.
Why Mergers Fail: Beyond the Financials
Despite strong financial projections and strategic alignment, mergers and acquisitions often fail to deliver their expected value. Studies show that between 70 and 90 percent of M&A deals either fail or fall short of their objectives, according to research by EY and Consultancy-me.com.
While leaders tend to focus on balance sheets, market share, and operational synergies, these numbers reveal a deeper problem: culture and human factors are often the silent deal breakers.
Financier Worldwide points to cultural misalignment, low employee engagement, and leadership disconnect as major reasons why integration efforts collapse after the deal closes.
This illustrates that the blind spot in most M&A strategies is human risk.
Human risk refers to the behavioral gaps that determine how well individuals and teams can adapt, connect, and perform under change. It is the missing piece in change management during mergers and acquisitions, where the focus is usually on systems and structure rather than people.
Traditional financial due diligence is designed to evaluate tangible assets, not change resilience, trust, or adaptability. Without assessing change resilience and human connection early, even the strongest financial logic can unravel when two cultures collide and people struggle to align around a shared way of working.
Understanding Company Culture in the M&A Context
Company culture is the collective heartbeat of an organization. It is shaped by shared values, beliefs, behaviors, and interpersonal dynamics that guide how people interact, make decisions, and solve problems. A strong company culture gives employees a clear sense of identity and belonging, creating alignment between what the organization says and what it does. It also drives engagement, collaboration, and trust; qualities that directly impact performance and innovation.
In the context of mergers and acquisitions, company culture becomes a defining factor in whether two organizations can truly integrate. When cultures align, teams adapt faster, collaboration flows more naturally, and the transition feels purposeful.
However, when there is a mismatch of values, leadership styles, or decision-making processes, friction quickly builds. Employees lose trust, communication breaks down, and human connection weakens. Research published on SpringerLink shows that cultural distance between merging companies can significantly reduce long-term performance, slow innovation, and prevent the realization of intended synergies.
In many cases, what appears to be a strategic or operational issue is actually a cultural one. The ability to manage and align culture during mergers determines whether a deal becomes a shared success story or another statistic in the long list of failed integrations.
The Role of Change Resilience and Human Connection in M&A Success
Many organizations approach mergers through a traditional change management lens, focusing on processes, timelines, and communication plans. While these elements are important, they often fall short when the workforce itself lacks the ability to adapt and connect. If a company’s culture is already weak in change resilience and human connection skills, even the best change management strategy will struggle to take hold. Successful mergers depend not just on managing change, but on ensuring that people have the behavioral skills to navigate it.
Change Resilience in Mergers
Change resilience is the ability of individuals and teams to stay steady, flexible, and forward-focused through uncertainty. In mergers, it determines how quickly employees adapt to new structures, systems, and leadership. There are six key subcategories that strengthen organizational adaptability.
- Emotional Regulation: Staying composed and effective under pressure.
- Adaptability: Adjusting easily to new expectations, roles, or environments.
- Problem-Solving Confidence: Believing in one’s ability to find solutions even when the path is unclear.
- Optimism: Maintaining hope and a positive outlook through transition.
- Persistence: Continuing to move forward despite challenges or setbacks.
- Change Literacy and Agency: Understanding how change works and taking ownership in navigating it.
Human Connection in Mergers
Human connection is the ability to communicate effectively, build trust, and collaborate across differences. During mergers, it enables employees from both sides to align, share information, and feel valued in a newly formed culture. The six key subfactors that create psychological safety and engagement consist of the following.
- Social Warmth: Helping others feel welcome, respected, and included.
- Empathy and Listening: Seeking to understand others’ experiences and emotions.
- Conversational Engagement: Communicating openly and effectively in daily interactions.
- Psychological Safety: Encouraging honesty, openness, and ownership of mistakes.
- Inclusion Awareness: Recognizing bias and reflecting on personal assumptions.
- Inclusion in Action: Actively ensuring others feel understood, valued, and respected.
Measuring the Human Risk: Why and How to Assess Before the Deal
Assessing culture and human risk before a merger is essential because mismatches in values, connection, and change resilience often lead to high turnover, disengagement, slower integration, and loss of value. Research from Consultancy-me.com highlights that many mergers underperform not because of poor strategy, but because cultural and human factors were never measured.
When leaders focus only on financials and operations, they overlook the human capital that drives every outcome. Employees are not cost centers; they are critical assets. Human capital may appear intangible, but with the right tools it can be measured as precisely as financial performance. Metrics such as adaptability, trust, and collaboration can become hard data points that guide decision-making.
To embed this into the M&A process, human risk assessment should be included in due diligence. Cultural resource management companies or tools like C2IQ can support this through structured stages:
- pre-deal assessment,
- integration planning,
- and post-deal monitoring.
C2IQ’s human risk mapping, team dashboards, and role-level insights make culture and connection measurable and actionable.
The Case for Early Action: Cultural Due Diligence, Not Just Financial
Organizations that prioritize culture early in mergers consistently achieve stronger results. Disney’s 2006 acquisition of Pixar is one of the best-known examples. Rather than forcing Pixar to adopt Disney’s way of working, leaders focused on preserving Pixar’s creative culture while aligning around a shared vision of storytelling excellence. The result was a seamless cultural integration, sustained innovation, and one of the most successful acquisitions in entertainment history.
Similarly, industrial company Konecranes began its merger process by running a full cultural baseline survey to define a shared target culture before integration began. The company implemented clear communication plans and leadership development aligned with this vision. Within two years, Konecranes exceeded its synergy goals, and its share price rose by more than 50 percent after the acquisition announcement.
These examples show that culture is not a “nice to have.” It is a critical part of mergers and acquisitions risk management, directly influencing performance, retention, and long-term value creation.
