What M&A advisers and post-merger-integration (PMI) consultants do

The services M&A advisers and post-merger-integration consultants provide, end to end.

Quick answer

M&A advisers run the transaction — strategy, valuation, the sell-side or buy-side process, diligence, structuring, negotiation and acquisition financing. Post-merger-integration (PMI) consultants take over after close — 100-day planning, synergy capture, operating-model and systems integration, and talent retention. Matchpoint provides both ends.

A practical decision process

A five-step process for scoping and selecting transaction and post-merger integration support.

  1. Define the deal thesis and integration outcomes: Record the value-creation case, critical assumptions, non-negotiables, Day One requirements and measures of success.
  2. Separate the workstreams: Set the scope for transaction execution, diligence, synergy validation, integration design, communications and the first 100 days.
  3. Prepare a comparable request for proposal: Give each candidate the same facts, deliverables, timetable, team requirements, decision rights and fee questions.
  4. Evaluate execution fit: Compare sector and cross-border experience, senior-team involvement, conflicts, references, deliverable quality and the ability to work with management.
  5. Establish governance before appointment: Agree workstream owners, escalation routes, reporting cadence, decision forums and the transition from signing through Day One and integration.

What M&A advisers do

M&A advisers guide and execute a merger, acquisition or divestment end to end: valuation, preparing the information memorandum, buyer or target identification, running a competitive process, coordinating diligence, structuring the deal and negotiating to close. They also arrange the acquisition financing — senior, mezzanine or unitranche debt with sponsor or management equity.

What post-merger-integration (PMI) consultants do

  • 100-day and full integration planning
  • Synergy identification, capture and tracking
  • Operating-model, systems and process integration
  • Organisation design and talent retention
  • Risk, culture and change management

Why running M&A and PMI together matters

When the same team quantifies synergies at deal stage and delivers them after close, decision ownership can remain continuous. Acquisition research documents elevated senior-management turnover in defined samples; the rate and value consequence depend on the cohort, period and transaction. In the GCC, integration planning should also map founder dependency and person-specific employer and work-authorisation routes. See the evidence-led PMI retention framework.

How this works in the GCC

UAE and GCC M&A also requires local analysis of trade-licence and work-authorisation obligations, end-of-service liabilities, ownership structures, country-specific merger control and sector approvals. Matchpoint provides senior-led, origination-to-close advisory and PMI in Dubai, Abu Dhabi and across the region. See M&A Advisory.
