Business handshake

Practice Area

Mergers & Acquisitions Advisory.

Architecting transformational deals that redefine market landscapes and unlock unprecedented shareholder value.

Beyond the Transaction

In the high-stakes arena of mergers and acquisitions, the actual transaction is merely the beginning. True value is realized—or destroyed—in the strategic rationale preceding the deal and the operational execution that follows. Green Brook approaches M&A not as brokers, but as strategic architects.

We advise corporate boards, private equity firms, and sovereign wealth funds through the entire lifecycle of a transaction. Our analysis goes deeper than financial modeling; we evaluate cultural synergy, operational integration risk, and long-term market positioning.

Our M&A Capabilities Include:

  • ■ Target Identification & Screening: Proactive sourcing based on rigorous strategic criteria.
  • ■ Commercial Due Diligence: Deep-dive analysis of market dynamics, competitive threats, and revenue sustainability.
  • ■ Synergy Valuation: Empirical modeling of cost and revenue synergies, stripped of optimistic bias.
  • ■ Post-Merger Integration (PMI): Managing the complex reality of combining distinct organizational cultures and IT infrastructures.

Case Study

Global Pharma Acquisition

Signed contract handshake

The Challenge

A leading European pharmaceutical firm sought to acquire a high-growth US biotech startup to bolster its oncology pipeline. Initial valuations were highly inflated, and cultural differences posed a significant risk to R&D continuity.

The Westfield Approach

We conducted a contrarian due diligence process, uncovering underlying regulatory risks in the target's pipeline that other advisors had overlooked. This allowed our client to renegotiate the purchase price down by 18%. Furthermore, we designed a customized integration plan that ring-fenced the biotech's innovative R&D culture while consolidating back-office operations.
