# Conducting Buy Side Due Diligence

Structures comprehensive buy-side diligence across financial, legal, commercial, and operational workstreams. Use when coordinating DD processes, building diligence checklists, or synthesizing DD findings for an acquirer or investor.

## When To Use

- Buyer or investor is evaluating a target company for acquisition, merger, or significant investment
- Corporate development team needs a structured DD checklist across multiple workstreams
- Deal team needs to synthesize findings from parallel workstreams into a consolidated diligence memo
- Advisor is preparing a diligence request list (DRL) to send to the sell-side
- Post-LOI / post-term-sheet phase where the data room is open or about to open

## Inputs To Gather

- **Deal parameters**: Target name, industry, transaction type (asset vs. stock purchase, merger, minority investment), indicative valuation, and deal timeline
- **Information Memorandum / CIM**: Sell-side marketing materials describing the target's business, financials, and growth story
- **Data room access or index**: VDR table of contents or document inventory to assess completeness
- **Prior diligence reports**: Any Phase I or preliminary findings from Red Flag reviews
- **Buyer's investment thesis**: Strategic rationale, synergy assumptions, integration priorities
- **Known risk areas**: Regulatory exposure, pending litigation, customer concentration, IP dependencies

## Workflow

### 1. Define Scope and Workstream Ownership

- Identify required DD workstreams based on deal type and target profile:
  - **Financial DD**: Quality of earnings (QoE), working capital analysis, debt/debt-like items, normalized EBITDA adjustments
  - **Legal DD**: Corporate organization, material contracts, litigation, regulatory compliance, IP ownership
  - **Commercial DD**: Market sizing, competitive positioning, customer cohort analysis, pipeline durability
  - **Operational DD**: Technology stack, supply chain, workforce composition, facility/lease obligations
  - **Tax DD**: Tax attributes, exposure analysis, structuring considerations [VERIFY jurisdiction-specific tax treatment]
  - **Environmental DD**: Phase I/II ESA status, remediation liabilities, permit compliance [VERIFY applicable environmental regulations]
  - **Insurance DD**: Policy adequacy, claims history, tail coverage requirements
- Assign workstream leads and set reporting cadence (typically weekly syncs with a consolidated tracker)

### 2. Build the Diligence Request List (DRL)

- Draft workstream-specific request lists with numbered items for VDR cross-referencing
- Prioritize Tier 1 (deal-critical) vs. Tier 2 (confirmatory) requests
- Include time-period specifications (e.g., "3 most recent fiscal years plus YTD interim period")
- Flag items requiring management presentations or expert sessions (e.g., technology deep-dive, customer reference calls)

### 3. Execute Workstream Reviews

- **Financial**: Reconcile CIM financials to audited statements; identify QoE adjustments (one-time items, pro forma run-rate expenses, related-party transactions); calculate locked-box or completion accounts working capital peg; map debt/debt-like items for enterprise-to-equity bridge
- **Legal**: Review articles of incorporation and bylaws; abstract material contracts for change-of-control provisions, assignment restrictions, and termination triggers; catalog pending or threatened litigation with exposure estimates; confirm IP ownership chain and freedom to operate [VERIFY specific IP registrations and encumbrances]
- **Commercial**: Validate revenue by customer, product, and geography; assess customer concentration (top 10/20 customers as % of revenue); evaluate contract renewal rates, weighted average contract life, and churn; pressure-test management's growth projections against independent market data
- **Operational**: Assess key-person dependencies; review technology architecture for scalability and technical debt; evaluate supplier concentration and single-source risks; confirm real property lease terms and capital expenditure requirements

### 4. Identify and Escalate Red Flags

- Maintain a running red-flag log with severity ratings (High / Medium / Low)
- High-severity triggers: material litigation undisclosed, revenue recognition irregularities, unrecorded liabilities, change-of-control consent failures, regulatory non-compliance
- Escalate high-severity items immediately to deal lead and legal counsel — do not wait for the final report

### 5. Synthesize Findings into DD Report

- Consolidate workstream summaries into a structured diligence memo:
  - Executive summary with go/no-go recommendation and key conditions
  - Workstream-by-workstream findings with supporting evidence references (VDR document numbers)
  - Quantified impact table: identified adjustments to enterprise value, working capital, or earn-out targets
  - Risk matrix mapping identified issues to proposed mitigations (reps & warranties, indemnities, escrow/holdback, purchase price adjustments, closing conditions)
  - Open items list with owners and deadlines

## Output

- **Diligence Request List (DRL)**: Numbered, workstream-organized document request schedule
- **Consolidated DD Report**: Executive summary, workstream findings, financial adjustments, risk matrix, and open items
- **Red Flag Memo** (if applicable): Standalone escalation document for deal-critical issues
- **Purchase Agreement Markup Inputs**: Specific rep & warranty requests, indemnity carve-outs, and disclosure schedule items informed by DD findings

## Quality Checks

- Every material finding cites a specific VDR document or management representation — no unsourced assertions
- Financial adjustments tie to audited financials or QoE schedules with clear bridging logic
- Risk severity ratings are consistent across workstreams (same rubric applied)
- Open items are assigned, dated, and tracked — none left as "TBD" without an owner
- Confirm all Tier 1 DRL items were received and reviewed; flag any seller non-responses
- [VERIFY] Regulatory and tax conclusions reflect the governing jurisdiction and current law
- [VERIFY] Change-of-control and consent requirements checked against the specific transaction structure (asset vs. stock)
- Final report reviewed by deal lead before distribution to investment committee or board
