Mergers and Acquisitions

In lower middle-market acquisitions, disciplined buy-side execution protects against overpayment, unassumed liabilities, and post-closing integration failure. A successful transaction requires rigorous diligence, precise purchase agreement structuring, and a clear path to value capture well before closing.

This checklist provides a phased operational and legal roadmap for corporate development teams, private equity sponsors, and strategic buyers executing domestic acquisitions.

Phase 1: Strategic Sourcing, Screening & Preliminary Review

• [ ] Strategic Thesis & Criteria Alignment: The target meets defined operational parameters (revenue threshold, EBITDA margins, geographic footprint, technology stack, and synergy potential).
• [ ] Mutual NDA Execution: Clean, balanced Non-Disclosure Agreement in place with explicit non-solicitation, confidentiality, and standstill protections.
• [ ] Teaser / CIM Financial Normalization: Review of the Confidential Information Memorandum (CIM) with preliminary stress-testing of pro-forma EBITDA add-backs and run-rate adjustments.
• [ ] Preliminary Valuation Modeling: Development of baseline, upside, and downside discounted cash flow (DCF) and comparable transaction models to establish a disciplined valuation boundary.
• [ ] Target Outreach & Management Introduction: Preliminary alignment with target leadership regarding culture, operational continuity, and transaction goals (full exit vs. rollover partnership).

Phase 2: Letter of Intent (LOI) & Transaction Structuring

• [ ] Deal Structure Determination: Optimal structural selection (Asset Purchase, Stock Purchase, or Forward/Reverse Triangular Merger) based on tax efficiency and liability insulation.
• [ ] Clear Working Capital Mechanism: The LOI explicitly defines the Net Working Capital (NWC) target methodology, 12-month historical normalization rules, and dispute resolution mechanics.
• [ ] Consideration Mix & Risk Allocation: Concrete terms established for cash at closing, seller financing, earnouts, rollover equity percentages, and indemnity escrow holdbacks.
• [ ] Exclusivity & Diligence Access: Enforceable 45-to-90 day exclusivity window granted, paired with prompt delivery of comprehensive Virtual Data Room (VDR) access.
• [ ] Key Employee Retention Terms: Preliminary term sheets or employment parameters for mission-critical target management outlined as a condition to closing.

Phase 3: Confirmatory Diligence Workstreams

Financial & Tax Diligence (Quality of Earnings)

• [ ] Third-Party QofE Report: Verification of trailing-12-month (TTM) revenue recognition, gross margin consistency, and customer-level profitability.
• [ ] Proof of Cash & Debt-Like Items: Cash-to-revenue reconciliation, identification of unrecorded liabilities, accrued PTO, customer deposits, deferred revenue, and equipment lease obligations.
• [ ] State & Local Tax (SALT) Nexus Audit: Review of multi-state sales/use tax collection liabilities, state franchise tax compliance, and remote workforce withholding.
• [ ] Target Tax Attribute Review: Evaluation of historical tax returns, S-Corp eligibility maintenance, tax basis of assets, and potential Section 338(h)(10) or Section 336(e) step-up elections.

Legal, Corporate & Compliance Diligence

• [ ] Cap Table & Ownership Verification: Complete chain-of-title review for 100% of target equity, including cancellation/settlement of outstanding options, warrants, or phantom equity.
• [ ] Material Contract Review: Analysis of top customer and supplier agreements for change-of-control triggers, anti-assignment clauses, termination-for-convenience provisions, and uncapped liabilities.
• [ ] Intellectual Property Ownership: Verification of executed assignment-of-inventions agreements for all current and former developers, employees, and 1099 contractors; review of USPTO trademark and patent dockets.
• [ ] Labor & Employment Review: Audit of independent contractor (1099) vs. employee (W-2) classifications, FLSA overtime exemptions, and current restrictive covenant enforceability.
• [ ] Litigation & Regulatory Standing: Background checks, lien searches (UCC), environmental assessments (Phase I ESA if real estate is acquired), and active operational permit validations.

Commercial & Operational Diligence

• [ ] Customer Concentration Stress Test: Direct or blind customer reference calls to evaluate churn risk, contract renewal probability, and key client dependencies (>15% revenue share).
• [ ] Technology & Cybersecurity Posture: Source code audits, open-source license compliance (GPL/copyleft), infrastructure scalability, and data privacy regulatory compliance.
• [ ] Supply Chain & Vendor Continuity: Evaluation of sole-source supplier dependencies, transferability of master vendor agreements, and pricing lock-ins.

Phase 4: Definitive Agreements & Risk Mitigation

• [ ] Purchase Agreement Negotiation: Drafting and negotiation of the Asset Purchase Agreement (APA) or Stock Purchase Agreement (SPA) aligned with LOI risk allocations.
• [ ] Representation & Warranty Framework: Alignment on general rep survival periods (typically 12–24 months), fundamental rep survival (statute of limitations or indefinite), and specific indemnity escrows.
• [ ] Rep & Warranty Insurance (RWI) Placement: If applicable ($20M+ deal size), securing buy-side RWI policy quotes, negotiating non-recourse boundaries, and finalizing exclusions.
• [ ] Rigorous Disclosure Schedule Review: Line-by-line examination of seller disclosure schedules against diligence findings to prevent unvetted liability exceptions.
• [ ] Definitive Ancillary Agreements: Finalization of Key Executive Employment Agreements, Non-Compete/Non-Solicit covenants, Rollover Unit Agreements, and Transition Services Agreements (TSAs).

Phase 5: Pre-Closing, Closing & Day-One Integration

• [ ] Third-Party & Regulatory Consents: Receipt of all required landlord consents, customer contract assignments, bank approvals, and regulatory transfer authorizations.
• [ ] Funds Flow & Settlement Statement: Finalization of payoff letters, UCC-3 termination filings for debt extinguishment, transaction fee disbursements, and closing wiring schedules.
• [ ] Pre-Closing Working Capital Estimate: Verification of the estimated closing balance sheet and resulting closing-day purchase price adjustment.
• [ ] Day-One Operational Plan: Implementation of IT/email access, banking cutovers, employee communications, and payroll continuity on day one.
• [ ] Post-Closing Milestones: Calendar tracking for 90-day post-closing working capital true-up, final tax elections, and integration milestone tracking.

Buy-Side Diligence Risk Matrix

Risk Area	Primary Deal Exposure	Structural Mitigation
Undocumented IP	Third-party infringement claims; inability to exclusively commercialize core software/tech.	Pre-closing assignment execution; fundamental representation status; full indemnity indemnity carve-out.
Customer Concentration	Sudden post-closing revenue decline upon contract expiration or ownership change.	Earnout / contingent consideration; closing condition on major customer consent; extended transition agreements.
Unrecorded Tax Nexus	Successor liability for multi-year uncollected state sales/franchise taxes.	Special tax indemnity escrow; asset purchase structure with clear excluded liabilities; voluntary disclosure agreements (VDAs).
Working Capital Gap	Target drains inventory or accelerates receivables collections immediately prior to close.	Detailed peg calculation methodology in LOI; trailing 12-month average mechanism; post-closing true-up escrow.
