Red flag due diligence report: Spotting key risks in M&A

In mergers and acquisitions (M&A), spotting red flags in time can make all the difference between success and failure. These warning signs, whether they are financial discrepancies, legal issues, or operational challenges, often go unnoticed until it’s too late. 

To prevent the worst-case scenario, dealmakers conduct red flag due diligence. It helps to quickly define the main problematic areas in the target’s operations that might cause the deal failure. 

This article explores the fundamentals of red flag due diligence, lists focus areas, and suggests what to include in a red flag due diligence report.

What is red flag due diligence?

Red flag due diligence is a process where buyers check for potential problems or risks in a deal before committing to it. The goal is to identify ‘red flags’ — warning signs that could indicate legal issues, financial trouble, or hidden liabilities in a target company. This allows buyers to make an informed decision or renegotiate deal terms.

For example, red flag due diligence might uncover deal breakers such as unpaid debts, lawsuits, or a poorly managed business. In short, it’s a focused health check to avoid unpleasant surprises.

The red flag due diligence process is typically initiated in the following use cases:

• Mergers and acquisitions
  When companies plan to buy or merge with another business, red flag due diligence helps spot critical problems like legal disputes, financial fraud, or hidden debts early. This can significantly help with decision-making before investing time and money in full-scope due diligence.
• Startup or small business investments
  Investors use red flag due diligence to quickly check for serious risks in the company, such as incomplete financial records, ownership issues, or poor legal compliance. This helps to avoid investing in companies that are likely to become unprofitable.
• Joint ventures and partnerships
  Before partnering with another company, businesses perform this review to uncover any risks that could harm the collaboration, like regulatory violations or a bad reputation.
• Real estate transactions
  Buyers or lenders conduct red flag due diligence to identify legal ownership issues, environmental concerns, or problems with property documentation.
• Supplier or vendor screening
  Businesses use it to check potential suppliers or vendors for any red flags, such as financial instability, unethical practices, or legal trouble.

When is red flag due diligence conducted?

Generally, red flag due diligence is performed before the actual due diligence. However, that’s not always the case. The main rule is that it’s used when there is a need to quickly identify critical risks in a potential deal or before making a significant investment. 

Here are the key situations when such a need may arise:

• During the early deal stages
  Before committing to a detailed, time-consuming due diligence process, buyers may conduct a red flag review to quickly assess whether any major risks exist. This helps decide if the deal is worth pursuing further.
• When time is limited
  In fast-moving deals, such as competitive acquisitions or distressed asset sales, there might not be enough time for a full investigation. Red flag due diligence allows buyers to focus on high-risk areas and make decisions faster.
• When the budget is tight
  Smaller deals or resource-limited buyers may opt for red flag due diligence instead of a full, costly review. It’s a way to identify deal breakers without spending heavily on detailed assessments.
• For high-risk targets
  When acquiring companies in financial trouble or high-risk industries, a red flag review quickly highlights critical problems like bankruptcy risks, regulatory violations, or poor operational controls.
• Before signing preliminary agreements
  Buyers often conduct red flag due diligence before signing term sheets, letters of intent (LOIs), or other preliminary agreements. This ensures they are aware of significant risks early and can adjust terms if needed.
• For reassessing the deal after new inputs
  If unexpected concerns arise during negotiations, a red flag due diligence review helps focus on the new risks to decide whether to proceed, renegotiate, or walk away.

Focus areas of red flag due diligence

Let’s take a look at the main areas to focus on in the search for potential red flags. 

Financials

Financial stability is one of the most important parts of due diligence. A target company with financial problems can cause serious issues after the deal and put a buyer at a significant risk of financial losses. 

The main financial issues to look for include:

• Hidden debts or liabilities
• Incomplete or inaccurate financial reports
• Cash flow issues
• Aggressive accounting

For instance, the lack of sufficient red flag due diligence was a reason why HP failed to identify serious accounting improprieties in Autonomy’s financial operations in 2011, which led to deal failure and HP’s financial losses.

Legal and compliance

The main red flags to look for in the legal operations of the target include:

• Ongoing lawsuits or legal problems that could cost a lot of money or hurt the company’s reputation
• Regulatory non-compliance
• Disputes over intellectual property, like patents or trademarks
• Risky contracts with unclear terms

For instance, regulatory and political red flags were one of the reasons why the Microsoft and TikTok deal never happened. The U.S. government imposed sanctions and regulations on TikTok’s Chinese parent company, ByteDance.

Operations

Operations are how the company runs day-to-day. If operations are inefficient or disorganized, it can cause problems after the transaction process.

Some of the most common red flags are:

• Inefficient processes that waste time or money
• Inaccuracies in shareholder agreements
• Relying on only a handful of key suppliers, customers, or employees, which can be risky if they leave or stop doing business
• Old or outdated technology that holds the company back from growing

Market position

This shows how strong the target company is in its industry and how it compares to competitors. If the company’s market position is weak, it could mean future growth challenges.

Red flags:

• Declining sales or losing market share to competitors
• Relying on just one product, customer, or market, which is risky if that product or market becomes less popular
• Industry changes that could hurt the company, like new competitors or rules

Human resources

If there are problems with employees, like high turnover or disputes, it can affect the deal’s outcome. That’s why talent retention is at the heart of successful integration.

The main red flags to look for:

• High turnover
• Unresolved labor disputes or employee claims that could lead to legal trouble
• Unclear employee contracts or compensation that might lead to disputes

IT and cybersecurity

Technology is essential for businesses, and weak IT systems or poor cybersecurity can cause serious risks. Considering the rising average cost of a data breach — $4.88 million, a 10% increase year-on-year — dealmakers should be careful when reviewing the target’s IT infrastructure and cybersecurity measures. 

Red flags:

• Old IT systems that can’t handle growth or change
• Weak cybersecurity that leaves the company’s data open to hackers or breaches
• Relying too much on outside companies for IT services without proper oversight

Red flag due diligence report: what to include

A red flag report is a document that summarizes the key findings after the red flag due diligence. 

Its components depend on many factors, such as the deal complexity or the specificity of the situation when the due diligence is performed.
