Creating an M&A due diligence checklist

Mergers and acquisitions (M&A) create many opportunities, but they also bring risks. Before any M&A transaction, it’s important that you perform thorough due diligence. 

An M&A due diligence checklist can help with this process. 

A well-crafted acquisition checklist should consider the buyer's specific requirements, the characteristics of the entities involved, their management and ownership structures, industry dynamics, and company histories. Additionally, the checklist should be adaptable, with the level of detail varying based on the nature of the transaction including size.

Below are typical due diligence areas that must be addressed in an M&A deal.

General corporate matters

Gather organizational documents and corporate records for a company and its subsidiaries. Including: 

  • Articles of incorporation and amendments
  • Bylaws and amendments
  • Meeting minutes
  • Organizational charts
  • List of current officers and directors
  • List of shareholders and the number of shares each holds
  • List of all states the company is qualified to do business in
  • Business licenses and permits
  • Good Standing and tax authority certificates


To gain a thorough understanding of the company’s financials, review the following:

  • Cash flows
  • Balance sheet
  • Quality of earnings
  • Accounting compliance
  • Any significant operating and financial trends
  • GAAP and SEC reporting compliance
  • Valuation and financial modeling
  • Operating or SG&A (selling, general, and administrative) expenses


Evaluating tax reports, filings, and agreements can help inform potential risks and opportunities in the transaction. Examine:

  • Federal, state, local, and foreign income or other tax filings
  • Sales and use tax reports
  • Audit and revenue agency reports
  • Tax settlement documents
  • Tax sharing or tax benefit agreements
  • Employment tax filings
  • Tax liens


The main goal of legal due diligence is to discover hidden liabilities – whether historical or pending – that could compromise the transaction. Be sure to perform the following:

  • Legal history review
  • Past and pending litigation review
  • Bankruptcy searches
  • Unpaid judgments and liens
  • Preliminary UCC searches
  • Legal entity structure mapping and post-close filing preparation
  • Legal obligation review
  • Debt structure and credit analysis

Antitrust and regulatory issues

The U.S. Department of Justice and U.S. Federal Trade Commission have upped scrutiny and enforcement of antitrust practices. Conducting antitrust due diligence can inform buyers of the antitrust liability risk associated with any transaction so they can take mitigating actions. 

Due diligence should also review all regulatory obligations, business licenses and permits, and certification requirements to identify potential non-compliance with industry regulations.

Consider the following: 

  • If the purchaser is a competitor of the target company, it's important to grasp and navigate any restrictions set by the company concerning the extent and timing of due diligence disclosure.
  • In cases where the company operates in a regulated industry and necessitates regulatory approval for an acquisition, understanding the complexities surrounding the pursuit and obtaining approval is crucial.
  • Review industry-specific business licenses and certifications.
  • Confirm if the company has been subject to antitrust or regulatory inquiries or investigations. 

Material contracts

Buyers should be vigilant regarding any contracts held by the target company that have the potential to affect the company adversely if they are terminated. Examples include:

  • Credit agreements, guaranties, and loans
  • Real estate leases/purchase agreements
  • Material contracts with suppliers or customers
  • Manufacturing contracts
  • Partnership or joint venture agreements
  • Equity finance agreements


Review each insurance policy held by the target company, including: 

  • General liability
  • Personal and real property
  • Product liability
  • Errors and omissions
  • Key-man, directors, and officers
  • Worker’s compensation


Commercial due diligence offers insights into the target company from a business standpoint. Typically, this involves an in-depth analysis of various factors that are commercially significant and provides insights into the target company's operating landscape and its prospects. There are several areas to cover: 

  • Evaluate strategy and growth plans
  • Interview customers to assess sales and marketing results
  • Business plan review
  • Overall competitive analysis
  • Understand brand value and customer loyalty
  • Review marketing strategies and arrangements
  • Review sales, distributor, agency and franchise agreements


The goal of this step is to understand daily operations, business efficiencies, and uncover any issues. Consider the following:

  • Working capital assessment
  • Manufacturing and operations evaluation
  • Inventory reports
  • Subcontractor, supplier, and vendor list and contracts
  • Procurement and supply review
  • Supply chain operations
  • Capacity analysis
  • Analysis of capital expenditures
  • And more

Property and assets

Review of all owned or leased property, including:

  • Valuation of property, equipment, and other tangible assets
  • Deeds, leases, and subleases
  • Rental income
  • Financing agreements
  • Conditional sale agreements
  • Environmental site assessments
  • Liabilities and obligations (liens, mortgages, property tax, etc.)

Management and workforce

General management and workforce considerations may include:

  • Key employee listing with salary, title and duties
  • Employment contracts and agreements
  • Employee and retirement benefits
  • Compensation plans
  • Description of labor disputes

Technology and data

Performing technical due diligence allows stakeholders to make informed decisions about the company's technological preparedness and integration readiness. The review should include: 

  • IT infrastructure
  • Software applications
  • Data management practices
  • Security and data protection policies and controls

Intellectual property

Intellectual property due diligence audits the scope and quality of any IP assets held by or licensed to the target company or individuals. This step should also address how IP is captured and protected by the company. 

  • Obtain a list of trademarks, copyrights, patents, trademarks, trade names, or service marks, both current and pending
  • Confirm ownership of IP 
  • Assess the quantity and quality of IP assets
  • Value intangible assets
  • Evaluate how IP is captured and protected to prepare for a transaction

Getting started

Due diligence plays a crucial role in enabling dealmakers to understand a transaction's nature, assess risks, and determine its compatibility with their portfolio. 

However, business deals and strategic decisions often unfold with strict time constraints. The pressure to meet deadlines can limit the thoroughness and comprehensiveness of the due diligence process. This can lead to overlooked details, incomplete analysis, and uninformed decisions.
