Tech Due Diligence: A Strategic IT Leader’s Role in M&A

Mergers and acquisitions (M&A) represent some of the most exciting opportunities for business transformation—but they also come with significant challenges, especially for IT leaders. From unifying systems to safeguarding against cybersecurity risks, the decisions made during tech due diligence shape the financial and operational success of a deal.

Welcome to the start of our Mergers & Acquisitions blog series! Over the next four weeks, we’ll dive deep into how IT and Finance leaders team up to drive M&A success. Today, we focus on the vital role IT leaders play during tech due diligence, laying the groundwork for seamless transitions and strategic growth. Later this week, we’ll explore financial due diligence—where Finance leaders evaluate risks, manage costs, and ensure that technology investments make financial sense.

When it comes to M&A, preparation is everything—and collaboration between IT and Finance is non-negotiable.

Market Insights: The Expanding Role of IT in M&A

Across industries, IT leaders are taking a more proactive role in preparing their systems for large-scale integrations during M&A. A January 2025 Reuters article highlights that organizations often inherit cybersecurity vulnerabilities from acquired companies, emphasizing the importance of IT due diligence in mitigating risks and ensuring seamless integrations.

With the increasing complexity of IT infrastructures, businesses that establish clear strategies for system compatibility, cybersecurity, and financial alignment position themselves for a smoother transition. M&A deals are no longer just financial transactions; they are digital transformations. Organizations that neglect the IT-Finance connection during due diligence often face post-merger disruptions, ballooning costs, and cybersecurity vulnerabilities.

Why IT Leadership is Central to M&A Success

IT leaders have moved from behind the scenes to the forefront of strategic decision-making. During M&A, their ability to identify risks, streamline integrations, and align technology with financial goals can make or break a deal.

As highlighted in a January 2025 Forbes report, due diligence isn’t just a checkpoint—it’s the key to unlocking post-merger value and preventing costly surprises.

Finance leaders rely on IT’s expertise to assess the financial impact of technology decisions—whether it’s evaluating the cost of system integrations, estimating cybersecurity investments, or calculating potential IT-driven synergies. This cross-functional partnership ensures that technology supports financial objectives rather than becoming a post-merger liability.

Key Focus Areas for Tech Due Diligence

1. Evaluating Legacy Systems & Cost Impact

Merging two companies often means integrating ERP, CRM, and other critical systems. IT leaders must assess:

• System compatibility—Can existing platforms be integrated, or are costly upgrades required?
• Cloud vs. on-premise considerations—What’s the most cost-effective infrastructure for scalability?
• Long-term financial impact—How will IT costs align with Finance’s budget forecasts?

2. Cybersecurity & Compliance Risks

Cybersecurity risks increase during M&A due to expanded attack surfaces and the need to share sensitive data. IT teams must evaluate:

• Existing security protocols and vulnerabilities at the target company.
• Compliance with GDPR, CCPA, or industry regulations.
• Cyber liability insurance and risk mitigation budgets—working with Finance to ensure security investments are justified.

A January 2025 Reuters article emphasizes that acquiring organizations inherit the security posture of the companies they purchase, making cybersecurity due diligence critical.

3. Data Governance & Financial Reporting Accuracy

Unified and accurate data is the foundation of successful integration. IT leaders must:

• Audit data quality and accessibility to avoid costly inconsistencies.
• Identify redundancies that could inflate integration costs.
• Ensure financial reporting systems align so Finance can track post-merger performance effectively.

Without proper IT oversight, financial leaders may struggle with inconsistent data, affecting decision-making and compliance.

4. IT Team & Vendor Analysis

Beyond systems, the human and vendor resources behind them are equally important. IT leaders must:

• Assess the capabilities of the target company’s IT team and collaborate with Finance to budget for necessary skill gaps.
• Review third-party vendor contracts to prevent unexpected post-merger expenses.
• Plan for continuity by renegotiating contracts as necessary.

Collaboration Between IT and Finance: The Key to M&A Success

The best M&A deals happen when IT and Finance work as true partners. During due diligence, this collaboration ensures:

• Technology costs align with financial projections to prevent budget overruns.
• Financial leaders understand IT’s impact on post-merger cash flow.
• IT investments are justified with clear ROI models.

Organizations that prioritize IT-Finance collaboration during M&A are more likely to achieve faster integration, stronger financial performance, and long-term operational success.
