M&A Solutions for Optimal Outcomes

Mergers and Acquisitions Advisory Services

Over 70% of M&A deals fail to achieve projected returns, often due to overlooked tax exposures, inadequate due diligence, or misaligned deal structures. Our Chartered Accountants and Tax Advisors ensure your transaction is optimised for value, compliance, and long-term success because, in M&A, the greatest risk isn’t the price you pay but the details you miss.

M&A Services That Protect Your Deal & Your Bottom Line

Most business owners dramatically underestimate the complexity of M&A. Last year, UK deals worth over £50m saw an average 22% drop in share price post-acquisition (PwC data). Why? Because mergers and acquisitions consulting isn’t about paperwork it’s about spotting the icebergs beneath the surface:

Tailored M&A Corporate Advisory

(Whether Buying or Selling)
Most sellers leave 20-35% of value on the table by accepting first offers or mishandling due diligence. Our M&A corporate advisory team specialises in manufacturing bidding wars we’ve secured 42% premiums for entrepreneurs by strategically timing disclosures and leveraging our Black Book of 1,200+ active buyers (PE firms, strategics, international acquirers). From crafting bulletproof Information Memorandums to shielding you from predatory warranty claims, we treat your business like our own.

Acquisition management is about discipline, not desperation. The average corporate overpays by 18% for targets that fail synergy tests (McKinsey). Our four-phase approach: 1) Screen targets against your strategic DNA, 2) Run shadow due diligence before bidding, 3) Structure tax-optimised offers with break clauses, 4) Lock in financing through our panel of 17 UK/EU lenders.
