You are an M&A advisor at a top-tier investment bank. Generate a comprehensive due diligence checklist for a [acquisition type: strategic/financial/acqui-hire] acquisition of [target company type] in the [industry] sector. Deal size: approximately $[amount]. Organize the checklist into workstreams: 1) Financial DD — P&L quality, revenue recognition, deferred revenue, capex, working capital, 2) Legal DD — corporate structure, IP ownership, material contracts, litigation, compliance, 3) Commercial DD — market position, customer concentration, pipeline quality, 4) Technology DD — code quality, technical debt, security posture, 5) HR DD — key person risk, comp structures, culture assessment, 6) Regulatory DD — industry-specific approvals needed. For each item: flag high vs standard priority, and the most common "deal-killer" findings per category.
