M&A Due Diligence: Getting It Right Before (and After) the Deal
London, EC2M 7EA United Kingdom
Synergies stall.
Costs rise.
Regulatory issues emerge.
Value leaks.
In 2026, due diligence is no longer a technical exercise. It is a strategic capability and a competitive advantage.
In this high-impact, half-day session led by Grant Thornton, senior deal leaders will unpack how acquiring firms are upgrading financial, regulatory, operational and technology due diligence to protect margin, reduce risk and accelerate growth.
Why attend?
This is a practical, peer-led session focused on real-world outcomes, not theory. We will explore:
• Where due diligence typically breaks down in wealth and advice transactions
• The hidden risks that only emerge post-completion
• How strong due diligence protects deal value and improves supervisory confidence
• The operational and technology challenges that undermine synergy cases
• What leading firms are doing differently in 2026
You will also hear directly from senior industry leaders on the questions they wish they had asked before signing.
