The Unspoken Success Factor: Placing Culture at the Heart of M&A

Mergers, acquisitions, and divestments are strategic endeavours that are often meticulously planned around financial models, technical integrations, and procedural alignments. Yet, time and again, the value promised by these transactions erodes, frequently because of one critical oversight: the insufficient consideration of People and Culture.

At the recent IMAA Post-Merger Integration Conference in Singapore the consensus was clear: treating people and culture as an afterthought, a 'soft' issue, is the single greatest barrier to realising M&A value. In my experience through numerous organisational changes, the people were frequently left confused, unaligned, and unmotivated, treated as administrative details. When do we start to treat ‘human resources’ as human beings?

The Strategy-Culture Nexus
The relationship between strategy and culture is inseparable; they 'join each other for breakfast together.' Think of your business strategy as the train: the value delivered to customers. Your culture provides the tracks: the way you deliver the value. Strong, well-maintained tracks enable the train to run fast and smoothly. Intentionally shaping this culture is essential to creating an environment where people can thrive and deliver on the business promise.

Cultural direction is set at the top. The C-Suite and the board's values, authenticity, and behaviour strongly influence the culture in the entire organisation. Hence, it is their responsibility to establish the cultural 'north star' for the company. The Human Resources team then acts as the strategic partner. Together they ensure the effective integration of people and culture into the fabric of the newly formed entity.

Measuring the 'Unmeasurable'
What is the key barrier that companies don’t engage in people and culture topics? A common misconception is the belief that culture cannot be measured and that impactful change takes too long. This is a myth. Integration teams often default to technical and financial topics, not because they are accurate but simply because they are more familiar to them. The reality: a well-defined target culture can be quantified.

A deliberate shift in values and behaviours alongside encompassing structural changes, can effectively nudge culture within a matter of months. For example, established, proven pulse surveys focusing on collaborative effectiveness, alignment, and sources of motivation allow an easy start. Furthermore, 'Gemba walks' and similar engagement practices allow us to genuinely feel how the integration is landing with frontline colleagues.

Decentralisation is Execution
While the future culture is defined by the C-Suite, a decentralised program enables a deep and consistent execution. When integration is rigidly pushed down, local teams struggle to make sense of a plan that appears oblivious to their specific regional, functional, or business unit context. Resistance builds quickly.

The solution is a framework: a strong north star from the top, guiding principles, clear boundaries, and a selection of tools and high-level processes. This framework allows local teams the flexibility to adjust the execution to their unique context. Change agents and connectors are vital here, humanising the process and ensuring the integration is people-centric, not just compliance-driven.

​
In many post-merger & acquisition situations, one party feels superior: “We have been the bigger company”, “We are the more successful team”, “Our processes are superior”, etc. These statements show that culture-related work is in its infancy. Successful integrations are marked by a crucial mindset shift: no party looks down on the other! They meet at the same eye level, creating a collective sense of belonging. This mindset begins with the authentic commitment of the senior leadership team.

The value you seek from the M&A is the 'yummy desert.' Achieving it requires treating culture not as a starter, nor a side dish; instead treat the people as the main course of your integration meal.
