Due diligence is a critical process in business transactions, ensuring financial stability, legal compliance, and risk mitigation. Whether in M&A, corporate finance, or real estate, due diligence helps businesses validate data before making high-stakes decisions.
What is due diligence?
The term “due diligence” refers to the systematic process of investigating and verifying an entity before entering into a business agreement. It ensures that all relevant financial, legal, and operational aspects of a transaction are thoroughly reviewed, minimising risks and preventing costly mistakes.
Origin and legal definition
The concept originates from legal and financial practices, with Merriam-Webster defining it as:
“Research and analysis of a company or organisation done in preparation for a business transaction (such as a corporate merger or purchase of securities).“
While its legal roots are clear, due diligence is widely applied in real estate, finance, M&A (mergers and acquisitions), corporate compliance, and regulatory processes.
Why due diligence is essential for business and M&A success
Due diligence serves as a risk mitigation tool, allowing businesses to:
- Validate information: Confirm the accuracy of financial statements, legal documents, and compliance records.
- Identify risks: Detect potential liabilities, hidden debts, regulatory issues, or reputational concerns.
- Ensure compliance: Adhere to laws and regulations, such as GDPR, financial reporting standards, or ESG mandates.
- Improve negotiation power: Strengthen the ability to negotiate better terms in mergers, acquisitions, or vendor contracts.
- Avoid costly mistakes: Reduce the likelihood of fraud, contractual disputes, or operational inefficiencies.
Due diligence principles: risk assessment & compliance
According to the UN Guiding Principles on Business and Human Rights, due diligence involves three key steps:
- Identify and assess risks – Understand potential threats to financial stability, reputation, or compliance.
- Prevent and mitigate – Take action to avoid or reduce risks, whether through restructuring, contract modifications, or legal measures.
- Accountability – Keep transparent records of how risks are identified and managed for legal and business integrity.
Types of due diligence
The due diligence process varies depending on the industry and transaction type. Here are the most common categories:
1. Financial due diligence
Examines a company’s financial statements, revenue streams, liabilities, and profitability to assess financial health before an acquisition or investment.
2. Legal due diligence
Ensures compliance with corporate laws, intellectual property rights, contracts, employment agreements, and litigation history.
3. Commercial due diligence
Analyses the market, competitors, customer base, and revenue potential to validate the target company’s business model and growth prospects.
4. Operational due diligence
Evaluates business processes, supply chain efficiency, IT infrastructure, and risk management to ensure operational stability.
5. Regulatory due diligence
Verifies compliance with industry-specific regulations, including financial reporting, environmental laws, data protection (e.g., GDPR), and anti-corruption laws.
6. ESG due diligence
Assesses a company’s environmental, social, and governance (ESG) impact, ensuring ethical business practices and sustainability compliance.
7. Technology and Cybersecurity due diligence
Investigates IT systems, software, intellectual property security, and potential cyber risks—critical in tech M&A and data-sensitive industries.
8. Vendor and third-party due diligence
Examines suppliers, contractors, and partners to mitigate supply chain risks, ensuring financial stability and compliance.
The due diligence process: step-by-step
Step 1: Define the objective
Clarify what needs to be examined and the expected outcomes, whether financial viability, compliance, or strategic fit.
Step 2: Gather and analyse information
Collect relevant documents, such as:
✔ Financial reports
✔ Legal contracts
✔ Operational data
✔ Compliance records
✔ Risk management policies
Step 3: Conduct risk assessment
Identify red flags, discrepancies, or potential deal-breakers through in-depth analysis.
Step 4: Validate findings and reports
Engage experts, such as auditors, legal advisors, or industry specialists, to verify information and provide professional insights.
Step 5: Decision-making and mitigation planning
Determine whether to proceed, renegotiate, or abandon the transaction based on the findings. If necessary, develop a mitigation strategy for identified risks.
Examples of due diligence in action
- Mergers & Acquisitions (M&A): A multinational corporation evaluates a startup’s intellectual property, revenue model, and legal risks before acquisition.
- Real estate: A commercial property investor reviews zoning laws, tenant agreements, and maintenance costs before purchasing an asset.
- Supply chain management: A global retailer investigates its suppliers for ESG compliance to ensure ethical sourcing and regulatory adherence.
