How Technical Due Diligence Uncovers Hidden Risks in M&A Deals: A Code Quality and Scalability Deep Dive

When one tech company buys another, a thorough technical review is essential. I’ll show you how a company’s tech approach can signal major risks—or opportunities—during an M&A deal.

Why Technical Due Diligence Matters in M&A

As an M&A consultant, I’ve learned that a company’s tech health can decide a deal’s fate. Investors need to look beyond the surface, checking code integrity, scalability, and hidden risks. It’s not just a checklist—it’s about understanding the real story behind the technology.

The Importance of Code Quality

Good code isn’t just about looks. I once worked on an acquisition where the product seemed flawless, but the code was messy, undocumented, and full of technical debt. These issues often point to bigger problems down the road.

Quick Tip: Check commit histories, coding standards, and test coverage. Tools like SonarQube or CodeClimate give you clear insights into code health.

Scalability: More Than Handling Growth

Scalability means your systems can grow without breaking. In one deal, we found the target’s setup couldn’t support more users without a full overhaul. That discovery changed the valuation completely.

Focus on these areas:

• How databases handle growth
• Load balancing and caching
• Architecture choices: microservices or monoliths

How to Analyze Technology Risks

Risk analysis isn’t just about bugs. It’s spotting outdated tools, security holes, and compliance gaps. In one case, we found a company using old libraries with known security issues—a huge red flag.

Checking Security

Security problems can kill deals fast. Use scanners like OWASP ZAP or Nessus, and review how incidents are handled. One weak spot can cause serious damage.

# Example: Check for outdated dependencies in Python
pip list --outdated

Reviewing Regulatory Compliance

In regulated industries like finance or healthcare, compliance is critical. Make sure the target follows standards like GDPR or HIPAA and has strong data policies. Mistakes here can mean fines and lost trust.

Steps for Effective Technical Due Diligence

Here’s a practical way to approach your review:

1. Audit the Code

Look for consistency, readability, and ease of maintenance. Watch for:

• Repeated or complex code
• Poor documentation
• Weak version control

2. Review Infrastructure

Check hosting, DevOps workflows, and backup plans. Make sure the infrastructure supports growth and reliability.

3. Test Performance

Run load tests to find bottlenecks. Tools like JMeter or Gatling help simulate heavy traffic and uncover weaknesses.

4. Talk to the Team

Engineers and tech leads share insights tools can’t. Their perspective reveals cultural and technical challenges.

Making Due Diligence Work for Your Deal

Technical due diligence isn’t just a safety step—it’s a strategic tool. By evaluating code, scalability, and risks, you avoid surprises and negotiate smarter. The goal is a smooth integration and lasting success.

Keep these priorities in mind:

• Thorough code reviews
• Scalability checks
• Risk and security analysis
• Team and culture fit

Build these into your M&A process, and you’ll reduce risks while finding hidden value. Solid due diligence helps turn acquisitions into wins.
