M&A value creation
Deliver deal value with a best of both culture.
Culture determines whether the value creation plan lives or dies. We help leadership teams, private equity sponsors, and integration leaders identify the cultural choices that matter most, and turn them into practical changes in leadership behaviour and ways of working across both organisations, before the deal, during integration, and when value is underdelivering after close.
Culture integration deserves the same rigor as financial and operational integration.
Why mergers destroy value
It's not the strategy that fails.
It's the culture assumptions.
2 in 3
mergers fail due to lack of attention to culture.
Most integrations do not fail because the strategy was wrong. They fail because the behavioural assumptions behind the value creation plan were never tested.
How are decisions actually taken? How is conflict handled? When those assumptions are wrong, the plan becomes a spreadsheet illusion. The real strategy of a company is not the strategy deck. It is the pattern of decisions people make every day, especially under pressure.
Integrations then fall into one of two traps. One culture dominates and suppresses the strengths of the other. Or both sides dilute themselves into a careful middle ground. Both destroy value. Outperformance requires the opposite: combining the best of both organisations by reconciling their differences.
"Where you don't want to be is in the middle of the two"
When to bring us in
Three moments. Eine question.
Whether you are structuring a deal, in the middle of integration, or recovering an underdelivered merger — the question is the same: will culture deliver the deal thesis?
Before signing — cultural due diligence.
We stress-test the behavioural assumptions behind the value creation plan, so you know which tensions will decide whether the synergies are real — before the deal closes, not after.
Mid-integration — unsticking synergy capture.
We identify the dilemmas blocking synergy capture and translate them into concrete changes in leadership behaviour and ways of working, before one-sidedness hardens into operating drag.
Recovering — value still in the deal.
We diagnose what the integration never reconciled, and help leadership teams design the changes in structures, decisions and behaviours that release the value still trapped inside the deal.
The approach
Four steps to a best-of-both culture.
From hidden tensions to a high-performing best-of-both culture: A structured process that moves leadership teams beyond abstract culture conversations and generic value statements to identify the dilemmas that matter most for integration success, develop solutions that combine the strengths of both organisations, and translate them into day-to-day behaviours and concrete changes that bring the value creation plan to life.
1 Recognise
Identify the dilemmas that matter strategically.
Data-driven diagnostics make front-of-house dilemmas and back-of-house operating assumptions visible and measurable.
2 Respekt
Map the logic of both sides, and the risk of one-sidedness.
Blended workshops assess both national and organisational cultures, and frame differences as attractive dilemmas rather than obstacles. Teams see why each side is partially right, and partially incomplete.
3 Abstimmen
Find higher-order solutions where each side strengthens the other.
Our Dilemma Reconciliation Process moves teams from either-or, and from both-and, to through-through — by asking how we can get more of value X through value Y, and more of value Y through value X.
4 Realise
Embed reconciliations in behaviours, structures and processes.
Without translation, values remain rhetorical and culture change cosmetic. We help leadership teams convert reconciliations into governance principles, decision rules, and the day-to-day behaviours that make the value creation plan deliverable.
"Until you can point to what a value means on a Tuesday morning in a meeting, in a customer call, in a project trade-off, in a hiring decision, and in a budget discussion, you do not have a value. You have a slogan."
What we surface
Predictable tensions. Reconcilable outcomes.
Every integration has its own specific dilemmas. Some show up again and again. Five tensions we typically see when two organisations meet:
Decisiveness and Analysis
Decisiveness without analysis is impulsive. Analysis without decisiveness is paralysis. Strength is fast decisions grounded in deep thinking.
Empowerment and Direction
Empowerment without direction creates drift. Direction without empowerment creates dependency. Strength is clear direction with real ownership.
Entrepreneurial and Process
Entrepreneurial without process is unscalable heroics. Process without entrepreneurship is bureaucracy. Strength is disciplined entrepreneurship.
Purpose and Cost Discipline
Purpose without cost discipline is unsustainable. Cost discipline without purpose is cynical. Strength is impact that pays for itself.
Warmth and Professionalism
Warmth without professionalism tips into favouritism. Professionalism without warmth becomes cold and transactional. Strength is caring and demanding at the same time.
These are the front-of-house dilemmas — the ones already visible in leadership conversations. Our diagnostic also maps the back-of-house operating assumptions that sit beneath the strategy deck: source of authority, view of hierarchy, how work gets done, how decisions and change happen, how conflict is handled, and what holds the system together.
Both sides are partially right. Both sides are partially incomplete. The value creation plan depends on reconciling these, not suppressing them.

Example clients
M&A integrations we've supported.
Standard Chartered – Grindlays Acquisition
When Standard Chartered acquired Grindlays Bank, THT worked on aligning cultural aspects across Asia, Africa and the Middle East — focusing on customer approaches, leadership expectations and cross-border collaboration, balancing Standard Chartered's structured governance with Grindlays' regional entrepreneurialism.
ING – Barings Merger
Following Barings' collapse, THT helped ING manage cultural healing and integration — rebuilding trust, aligning risk-management mindsets and reconciling Dutch and British leadership styles to embed a forward-looking culture focused on resilience.
Air France – KLM Merger
After the high-profile airline merger, THT worked with Air France–KLM to address cultural tensions between French and Dutch leadership and operational teams. The focus was harmonising decision-making, service standards and employee engagement while respecting national cultural differences — improving cooperation and aligning customer-facing behaviours.
Shell – BG Group Merger
Shell's 2015 acquisition of BG Group required integrating two energy giants with different cultural backgrounds: Shell's process-driven, structured style versus BG's more entrepreneurial, agile approach. THT supported the leadership teams in reconciling these differences — particularly around risk appetite, decision-making speed and innovation — helping the combined entity avoid cultural clashes and harness synergies.
