Why M&A Deals Fail: Capability, Culture, and David Perry’s OSCAR Due Diligence FrameworkCharlie interviews David Perry, an experienced mid-cap M&A and growth operator, about how business has changed since the 1980s (more data/AI, different communication, more systems and safety), his early turnaround of a struggling manufacturing firm, and lessons from scaling and integrating international companies. David argues many acquisitions miss a key diligence gap: assessing whether a business is structurally capable—people, processes, strategy, communication—to deliver investor expectations, which contributes to high post-deal underperformance. He shares examples of multinational silos, culture-building through shared values and regular in-person conferences, and distribution/partner networks that succeed only when they’re trained and supported for mutual benefit. David introduces OSCAR (Operational Strategy & Capability Assessment), built on his “Seven Pillars” and a capability maturity model, using 102 scenario-based questions to triangulate alignment gaps across leadership, sales/marketing, operations, and divisions.00:00 Meet David Perry01:24 From Small Factory to Midcap02:28 Business Then vs Now04:10 Safety and Shop Floor Stories06:01 Simple Metrics and Patterns07:50 Why M&A Deals Fail11:00 Capability Due Diligence Gap13:20 Breaking Silos to Scale17:17 Culture and Cohesion Wins23:05 Building Distribution Networks26:15 Partner Programs That Work32:11 AI Powered Capability Audits34:48 Big Company Pivot Challenges35:34 Shared Values Alignment37:57 Change Starts Where People Are41:12 Post Acquisition Shockwaves42:05 When Integration Goes Wrong45:06 Contract Chaos Before Exit48:07 Smart BRG Origin Story52:54 Building A Scalable Framework57:07 Oscar Capability Assessment01:06:03 AI Strategy And Gaps01:07:47 Growth Ceilings And Mindsets01:09:46 Learning By Doing01:11:24 Learning Through Failure01:11:46 Persistence and Asking Questions01:12:48 M&A Missteps and Integration01:15:09 Selling UK vs US01:19:23 Going Global With Local Teams01:22:03 UK Deal Market Reality Check01:25:31 Exit Readiness and Business Leakage01:26:46 Scaling Pains and Cost of Growth01:32:39 Modern Sales Touchpoints01:36:47 BD vs Account Management01:39:30 Customer Handover and Buyers Remorse01:43:16 Wrap Up and Part Two
