Definition

M&A Advisory Boutiques are specialist advisory firms whose principal activity is advising clients on mergers, acquisitions, divestitures and related corporate transactions, typically without the full product range of a diversified bank.

Overview

Boutiques vary from global independent advisers to small sector-focused firms. Their appeal may include senior-led execution, perceived freedom from lending conflicts and specialized relationships. The relevant comparison is not size alone: mandate complexity, cross-border reach, financing capability, sector evidence and conflict position all affect suitability.

Scope of advisory work

Strategic advice

Transaction rationale, alternatives, board materials and approach strategy.

Process execution

Preparation, counterparties, diligence, negotiation and timetable.

Specialist judgment

Sector knowledge, valuation, defence and senior stakeholder counsel.

Typical engagement

  1. Mandate: define objectives, confidentiality, scope, conflicts and success criteria.
  2. Preparation: analyse valuation, positioning, materials and transaction perimeter.
  3. Market engagement: identify counterparties and manage approaches or bids.
  4. Negotiation: coordinate diligence, structure, price and key protections.
  5. Completion: support approvals, documentation, announcement and closing conditions.
