The Importance of Due Diligence in Corporate Transactions

The success of corporate transactions—whether mergers, acquisitions, joint ventures, or asset purchases—hinges not only on deal terms but on the quality and depth of due diligence conducted beforehand. For attorneys advising companies on transactional matters, due diligence is a critical investigative and risk assessment tool that can spell the difference between a profitable deal and a costly disaster.

Due diligence allows the acquiring party to confirm the value of the target business, uncover potential liabilities, assess compliance risks, and refine deal structure. It enables buyers and investors to make informed decisions and negotiate protections before closing. This article explores why due diligence is so essential in corporate transactions, what it typically includes, and how to conduct it efficiently and effectively.

What Is Due Diligence?

Due diligence is the process of investigating and evaluating a business or entity before entering into a formal agreement. It is designed to verify the information provided by the target company, uncover material issues, and ensure that there are no hidden liabilities that could jeopardize the deal.

There are two sides to due diligence:

Buy-side due diligence, conducted by the acquiring party or investor

Sell-side due diligence, conducted by the target company to prepare for scrutiny and identify red flags early

Although typically associated with acquisitions, due diligence is critical in many other contexts, such as financing arrangements, equity investments, and strategic partnerships.

Why Due Diligence Matters

Thorough due diligence provides several key benefits in corporate transactions:

Risk Mitigation

The primary goal of due diligence is to identify legal, financial, operational, and regulatory risks. These may include:

• Pending litigation or regulatory actions
• Undisclosed debts or liabilities
• Deficient contracts or IP ownership issues
• Environmental compliance concerns
• Employment or tax violations

By identifying these issues early, the buyer can adjust the purchase price, seek indemnities, or walk away before becoming legally bound.

Valuation Verification

Due diligence helps the buyer confirm that the target’s stated value reflects its actual condition. This includes validating financial statements, customer contracts, vendor relationships, and key assets.

Strategic Alignment

Beyond risk, due diligence helps evaluate whether the target aligns with the buyer’s business objectives, culture, and long-term goals. Issues like incompatible technology, cultural mismatch, or workforce instability may affect integration success.

Deal Structuring

Findings from due diligence inform decisions about how to structure the transaction (e.g., asset vs. stock purchase), allocate risk, draft indemnification clauses, or establish escrow accounts.

Core Areas of Corporate Due Diligence

While due diligence can be broad and tailored to the specific deal, it generally includes the following key categories:

Corporate Structure and Governance

• Articles of incorporation, bylaws, operating agreements
• Board minutes and resolutions
• Shareholder agreements and equity capitalization
• Subsidiaries and affiliate relationships

Financial and Tax

• Audited financial statements and interim reports
• Accounts receivable and payable
• Tax returns, audits, and compliance records
• Off-balance sheet liabilities

Legal and Regulatory

• Pending or threatened litigation
• Compliance with applicable laws (e.g., antitrust, securities, employment)
• Licenses, permits, and governmental approvals

Contracts and Obligations

• Material customer and vendor agreements
• Leases, loans, and credit arrangements
• Non-compete, exclusivity, and change-of-control clauses
• Termination and assignment provisions

Intellectual Property

• Ownership and registration of patents, trademarks, copyrights
• Software licenses and development agreements
• Trade secret protections
• IP litigation or infringement claims

Employment and Benefits

• Employee rosters and compensation
• Independent contractor classifications
• Benefits plans and retirement obligations
• Union relationships or labor disputes

Environmental and Real Estate

• Property ownership, leases, and easements
• Environmental assessments or regulatory violations
• Zoning and land use compliance

The Role of Legal Counsel in Due Diligence

Corporate attorneys play a central role in managing due diligence. This includes:

• Developing a diligence checklist tailored to the transaction and industry
• Coordinating review teams across legal, tax, finance, and HR departments
• Communicating with opposing counsel to request and clarify information
• Analyzing red flags and advising the client on risk allocation
• Drafting and negotiating protective clauses such as reps and warranties, indemnification, and closing conditions
  

In many cases, legal counsel is also responsible for overseeing virtual data rooms, managing timelines, and ensuring consistent documentation of findings.

Best Practices for Efficient Due Diligence

To make due diligence as effective—and efficient—as possible, keep the following best practices in mind:

Start Early

Begin due diligence as soon as an LOI or term sheet is signed. Early access to key documents reduces last-minute delays and surprises.

Tailor the Scope

Avoid a one-size-fits-all approach. Focus diligence efforts on high-risk or high-value areas based on deal size, industry, and structure.

Use Checklists and Templates

Standardized checklists ensure consistency and help teams track requests and responses. Customize as needed.

Leverage Technology

Use secure virtual data rooms with indexing and search features. Digital tools can streamline reviews and facilitate cross-team collaboration.

Maintain Confidentiality

Ensure NDAs are in place and carefully manage access to sensitive documents—especially when dealing with competitors.

Communicate Frequently

Keep clients updated with status reports, issue summaries, and recommendations. Diligence findings often influence go/no-go decisions.
