6. Analyze the data: 

Thoroughly analyze the collected data to identify any potential red flags or areas of concern. Financial statements, legal paperwork, market research, and operational reports are reviewed. Check for inconsistencies, contradictions, and unreported information that could affect the merger or acquisition.

7. Assess risks and opportunities: 

Evaluate the identified risks and opportunities based on their potential impact on the business. Prioritize deal risks that could significantly impact financial, legal, operational, or reputational elements. Identify any transaction-related synergies or growth prospects.

9. Prepare a due diligence audit: 

Compile all findings, risks, opportunities, and recommendations into a comprehensive due diligence audit report. The due diligence report should clearly state major findings, risks, and recommendations. To explain the investigation’s results to stakeholders, the report should be organized and straightforward.

13. Arrangements, negotiation, and deal structuring: 

Based on the findings of the due diligence process and the valuation of the target company, negotiate the terms of the merger or acquisition. Consider purchase price, payment structure, and post-transaction duties. Work closely with legal consultants and financial experts to structure the acquisition to maximize value and minimize risk.

14. Sales and IT securities: 

Assess the sales and IT security measures of the target company to identify any potential vulnerabilities or risks. Check the company’s sales methods, client data protection, and IT infrastructure for industry best practices and regulatory compliance. Suggest ways to boost sales and IT security.

15. Employee retention and integration: 

Evaluate the target company’s employee retention rates, talent management strategies, and culture fit. Identify any potential challenges or risks related to employee integration and develop a plan to address them. Ensure that key employees are motivated and incentivized to stay with the company post-merger or acquisition.

How Long Does M&A Due Diligence Usually Take?

On average, M&A due diligence typically takes between 30 and 90 days to complete. The acquiring business can analyze the target company’s financials, operations, legal and regulatory compliance, and other crucial areas in this timeframe. Depending on the deal, the length may be longer or shorter.
