Technology is becoming increasingly central to M&A strategy, valuation, and post-deal value creation. PwC’s 2026 M&A outlook describes technology as one of the sectors driving the concentration of global deal activity and notes that AI is reshaping both deal strategy and the diligence process itself.
At the same time, technology investors are becoming more selective. PwC’s 2026 US technology deals outlook notes that traditional software businesses are being reassessed as buyers evaluate AI resilience, monetization potential, infrastructure requirements, and the defensibility of existing workflows.
For buyers, that raises the stakes of M&A technology due diligence.
It is no longer enough to confirm that a target’s software works today. Investors need to understand whether the technology can support the growth assumptions behind the deal, what risks are being inherited, how difficult integration may be, and what engineering investment could be required after closing.
A strong M&A technology due diligence process should ultimately help answer three questions:
- What material technology risks are we acquiring?
- Can the current technology support the investment thesis?
- What needs to happen after close to protect and create value?
Before diving deeper, review our tech due diligence checklist for a broader view of the architecture, code quality, cybersecurity, infrastructure, scalability, engineering, data, and AI areas investors should assess before a transaction.
This guide outlines three practical ways buyers can make M&A technology due diligence more focused, evidence-based, and useful for post-acquisition execution.
What Is M&A Technology Due Diligence?
M&A technology due diligence is an independent assessment of the technology assets, capabilities, risks, and engineering organization behind a potential merger or acquisition.
The objective is to determine whether the target’s technology supports the strategic and financial assumptions behind the transaction.
Depending on the target and scope of the assessment, M&A technology due diligence may examine:
- Software Architecture
- Source Code Quality
- Technical Debt
- Cybersecurity
- Cloud and Infrastructure
- Scalability and Performance
- Software Integration
- Data and AI Readiness
- Software Development Processes
- Quality Engineering and Testing
- Engineering Organization and Key-Person Risk
- Product and Technology Roadmap
- Third-Party Technologies and Licensing
These findings should not remain isolated technical observations.
A material architecture constraint, for example, may affect scalability. Significant technical debt may consume engineering capacity after close. Weak APIs may make integration more difficult, while fragmented data may delay analytics or AI initiatives.
The value of M&A technology due diligence therefore lies in translating technical evidence into questions that matter to the transaction:
Could this issue affect growth, integration, post-close investment, value creation, or the ability to execute the investment thesis?
Why M&A Technology Due Diligence Matters More Today
M&A technology due diligence has become increasingly important because technology is no longer simply an operational function inside many businesses.
For software and technology-enabled companies, architecture, data, engineering capabilities, AI readiness, and digital products may be fundamental to the value of the asset itself.
AI is adding another layer of complexity. PwC notes that technology dealmakers are increasingly evaluating whether software assets are positioned to benefit from AI or vulnerable to AI-native competition. Diligence is consequently expanding toward questions around monetization, infrastructure, data, and defensible workflows.
Software investors are already responding to that uncertainty. Reporting in 2026 has shown that private equity software buyout activity has slowed as buyers reassess traditional software business models against potential AI disruption.
This means technology diligence now serves two related purposes.
Protect Against Downside Risk
Buyers need to identify issues that could materially change the assumptions behind the transaction, including:
- Security Exposure
- Hidden Technical Debt
- Unsupported Technology
- Scalability Constraints
- Integration Complexity
- Key-Person Dependencies
- Poor Data Foundations
- Weak Engineering Processes
Identify Opportunities for Value Creation
The same assessment can identify areas where technology improvement may accelerate performance after close.
Examples may include:
- Application Modernization
- Platform Consolidation
- Systems Integration
- Cloud Optimization
- Quality Engineering
- Data Engineering
- AI Readiness
- Improved Software Delivery
M&A technology due diligence therefore should not only ask:
“What is wrong with the technology?”
It should also ask:
“Where can technology become a lever for value creation after the acquisition?”
3 Tips for More Effective M&A Technology Due Diligence
Start With the Investment Thesis, Not the Checklist
A technology assessment should begin with the assumptions behind the transaction.
Before reviewing source code, infrastructure, architecture, or engineering processes, the diligence team should understand what the buyer expects the technology to enable after the acquisition.
For example:
- Is revenue expected to scale significantly?
- Will the company enter new markets?
- Is the buyer planning a bolt-on integration?
- Will products or platforms be consolidated?
- Does the investment thesis depend on faster product delivery?
- Is AI expected to improve margins or product differentiation?
- Will the business require significant modernization?
- Is the target expected to operate independently or become part of a broader platform?
These assumptions determine which technology risks are material.
A tightly coupled architecture may be manageable if the target will remain relatively independent.
The same architecture could become a major investment issue if the deal assumes rapid product consolidation or integration with another portfolio company.
Similarly, technical debt should not automatically be treated as a red flag. The relevant question is whether it could prevent the company from executing the growth plan.
Questions Buyers Should Ask
- Which technology capabilities are essential to the investment thesis?
- What growth assumptions depend directly on the software platform?
- What technology changes are expected during the ownership period?
- What systems may need to integrate after close?
- Where could technology constrain revenue growth or operational improvement?
- How important are data and AI to the value-creation plan?
- What technical risks could materially change those assumptions?
Why It Matters
Starting with the investment thesis helps diligence teams distinguish normal engineering imperfections from material investment risks.
That keeps the assessment focused on issues that could actually influence the transaction rather than producing an undifferentiated list of technical findings.
For private equity buyers, KMS Technology approaches diligence from this investor-aligned perspective, focusing technical analysis on the capabilities and risks most relevant to the investment thesis.
Validate Technology Claims With Direct Evidence
Management presentations, architecture diagrams, roadmaps, and technical documentation provide valuable context during M&A technology due diligence.
But they should not be the only source of truth.
Where access allows, key technology assumptions should be validated through direct evidence from the systems, codebase, infrastructure, and engineering environment.
Relevant evidence may include:
- Source Code Repositories
- Commit History
- Architecture Documentation
- Cloud and Infrastructure Configuration
- CI/CD Pipelines
- Automated Test Suites
- Security Information
- Dependency Inventories
- Product Roadmaps
- Incident History
- Engineering Metrics
- Interviews With Technology Leaders
For example, management may describe the platform as highly scalable.
A diligence team should examine whether application architecture, databases, APIs, infrastructure utilization, performance history, and deployment practices support that claim.
Similarly, management may describe technical debt as manageable.
A deeper software code review can help determine whether the debt is localized to peripheral areas or embedded across critical parts of the product.
Investor Red Flag
Red Flag: Material technology claims cannot be validated through code, architecture, infrastructure, operational evidence, or engineering practices.
Why It Matters
Unvalidated assumptions can cause buyers to underestimate:
- Remediation Requirements
- Scalability Limitations
- Integration Complexity
- Engineering Capacity Needs
- Security Exposure
- Post-Close Technology Investment
The purpose of diligence is therefore not simply to collect information.
It is to verify the technology reality behind the investment narrative.
Need an independent view beneath the management narrative? KMS Technology’s technical due diligence practitioners assess architecture, source code, infrastructure, security, and engineering practices to help buyers validate the technology behind the transaction.
Translate Findings Into Post-Close Priorities
The most useful M&A technology due diligence assessment does not end with a report listing technical issues.
It should help investors understand what needs to happen next.
Findings should therefore be prioritized based on materiality, timing, and impact on the investment thesis.
Pre-Close Considerations
These are issues that require clarification, further investigation, or mitigation before completing the transaction.
Examples may include:
- Severe Cybersecurity Exposure
- Intellectual Property or Licensing Risk
- Unsupported Core Technologies
- Critical Scalability Constraints
- Material Technology Claims That Cannot Be Validated
- Significant Data or Compliance Concerns
Immediate Post-Close Priorities
These are material issues that should be addressed early to protect business continuity or reduce exposure.
Examples may include:
- Security Remediation
- Production Reliability Improvements
- Critical Infrastructure Changes
- Key-Person Risk Mitigation
- High-Risk Technical Debt
- Operational Monitoring Gaps
First 100-Day Technology Initiatives
These initiatives help stabilize the technology environment and begin executing the investment thesis.
They may include:
- Integration Planning
- Architecture Modernization
- Quality Engineering Improvements
- Cloud Optimization
- Data Consolidation
- Engineering Process Improvements
- AI Readiness Assessment
Longer-Term Value-Creation Opportunities
Over the broader investment period, technology findings may create opportunities for:
- Application Modernization
- Systems Integration
- Platform Consolidation
- Data Engineering
- Cloud Transformation
- AI-Native Product Engineering
- Software Delivery Improvement
The objective is to transform diligence from a one-time assessment into the first version of the post-close technology roadmap.
Once material risks are clear, KMS can continue supporting portfolio companies across Application Modernization, Systems Integration, Cloud & DevOps, Data Engineering, Quality Engineering, and AI initiatives.
What Technology Risks Should Buyers Prioritize?
Most mature software environments contain some technical debt, aging components, inconsistent documentation, or areas that could benefit from improvement.
Not every issue should influence the transaction.
M&A technology due diligence should distinguish routine engineering work from findings that could materially affect the investment.
| Priority | What It Means | Example | Potential Deal Impact |
| Critical | Could materially affect the transaction or investment thesis | Severe security exposure or unsupported core platform | Deal risk, valuation implications, immediate remediation |
| High | Requires substantial post-close investment | Major technical debt or scalability constraint | Higher engineering investment, slower value creation |
| Medium | Manageable weakness requiring planned improvement | Testing maturity or documentation gaps | Additional operational effort |
| Low | Routine engineering improvement | Localized refactoring | Limited transaction impact |
Investors should evaluate whether each major finding could affect:
- Revenue Growth
- Customer Continuity
- Product Scalability
- Security and Compliance
- Engineering Capacity
- Integration
- Post-Close Capital Requirements
- Value-Creation Timing
- Investment Thesis Execution
A useful diligence report therefore should not prioritize findings based solely on technical severity.
It should prioritize them according to investment materiality.
Key Areas to Assess During M&A Technology Due Diligence
While every transaction requires a different scope, several areas consistently matter when evaluating technology-driven businesses.
Software Architecture and Scalability
Assess whether the architecture can support expected growth and whether expansion would require incremental improvements or fundamental reengineering.
Key questions include:
- Can the platform support projected usage growth?
- Are major architectural bottlenecks already visible?
- Is the system modular enough to evolve?
- What infrastructure or architecture investment may be required as the company scales?
Source Code and Technical Debt
Code quality provides evidence about maintainability, development velocity, security, and the effort required to evolve the product.
Investors should evaluate:
- Maintainability
- Complexity
- Automated Testing
- Dependency Health
- Security Practices
- Code Ownership
- Technical Debt
A detailed software code review can help distinguish ordinary improvement opportunities from issues that could consume significant engineering capacity after close.
Cybersecurity
Security findings may create financial, regulatory, customer, and reputational exposure.
Technology diligence should consider areas such as:
- Authentication and Authorization
- Application Security
- Vulnerability Management
- Data Protection
- Security Testing
- Incident History
- Secrets Management
- Third-Party Security Dependencies
Cloud and Infrastructure
Investors should understand whether infrastructure is resilient, scalable, observable, and economically sustainable.
Important areas include:
- Cloud Architecture
- Deployment Automation
- Availability
- Disaster Recovery
- Monitoring
- Infrastructure Costs
- Capacity Management
- Environment Management
Software Integration
When integration forms part of the post-acquisition plan, buyers should evaluate whether target systems, applications, APIs, and data can realistically connect with the broader technology environment.
Poor integration readiness may delay expected synergies and increase engineering effort after close.
A deeper software integration due diligence assessment can help surface architecture, API, data, security, and system dependency risks before the transaction.
Data and AI Readiness
AI is changing both software competition and technology investment assumptions.
Investors need to determine whether the target has the data, architecture, governance, infrastructure, and engineering capabilities needed to execute its AI roadmap.
An AI-enabled feature does not necessarily mean an organization is AI-ready.
Important areas include:
- Data Quality
- Data Accessibility
- AI Governance
- Architecture Flexibility
- Model and Vendor Dependencies
- AI Security
- MLOps Capabilities
- AI Infrastructure Economics

What Buyers Should Receive From M&A Technology Due Diligence
Technology diligence should provide more than a technical inventory.
The final output should translate evidence into a decision-oriented view that helps investors understand what they are buying and what the technology may require after close.
A useful assessment may include:
- Executive Assessment of Technology Health
- Material Technology Risks
- Architecture and Scalability Findings
- Source Code and Technical Debt Assessment
- Cybersecurity Findings
- Infrastructure and Cloud Assessment
- Integration Dependencies
- Data and AI Readiness
- Engineering Organization Observations
- Prioritized Remediation Actions
- First 100-Day Technology Priorities
- Longer-Term Modernization Opportunities
The assessment should ultimately help answer:
What are we inheriting, what could affect the transaction, and what technology investment may be required after close?
This is where M&A technology due diligence moves from an engineering exercise into an investment decision tool.
How KMS Supports M&A Technology Due Diligence
KMS Technology brings hands-on engineering expertise into M&A technology due diligence.
Rather than approaching diligence only from a consulting perspective, our senior engineers, architects, product experts, and technology practitioners assess how the target’s software actually works across architecture, source code, infrastructure, security, engineering practices, and product delivery.
KMS reports having completed more than 70 technology assessments for organizations entering M&A transactions, supporting clients across $11.8 billion in acquisition value.
Our assessment capabilities can cover:
- Software Architecture
- Source Code Quality
- Technical Debt
- Infrastructure and Cloud
- Cybersecurity
- Scalability and Performance
- Engineering Processes
- Software Quality and Testing
- Technology Organization
- Integration Readiness
- Data and AI Readiness
- Product and Technology Roadmap
For private equity firms and strategic buyers, the objective is not to identify every technical imperfection.
It is to distinguish routine engineering issues from findings that could affect:
- The Investment Thesis
- Scalability
- Post-Close Capital Requirements
- Integration
- Execution Risk
- Technology Value Creation
Because KMS also builds, integrates, modernizes, and scales software platforms, diligence findings can continue into implementation when portfolio companies need post-close engineering support.
Final Thoughts
M&A technology due diligence has become increasingly important as software, data, AI, and digital capabilities become more closely connected to both transaction risk and future value creation.
The strongest diligence assessments do more than verify whether a target’s technology works.
They help buyers determine:
- Whether the technology can support the investment thesis
- Which risks could materially affect the transaction
- What technology investment may be required after close
- Where technology improvements could accelerate value creation
Almost every technology company has technical debt, architectural trade-offs, or areas where engineering could improve.
The more useful question is not:
“Does this target have technical problems?”
It is
“Which technology issues matter to this investment, and what should we do about them?”
Need greater confidence before your next merger or acquisition?
KMS Technology’s Tech Due Diligence Services help buyers uncover material technology risks, validate scalability, and translate technical findings into actionable post-deal priorities.
FAQ
What is M&A technology due diligence?
M&A technology due diligence is the assessment of a target company’s software, architecture, infrastructure, cybersecurity, engineering organization, data, and technology capabilities before a merger or acquisition.
The goal is to identify technology risks and determine whether the target can support the strategic and financial assumptions behind the transaction.
What does M&A technology due diligence include?
The scope may include architecture, source code, technical debt, security, cloud infrastructure, scalability, software integration, engineering processes, quality engineering, data readiness, AI readiness, third-party dependencies, and the technology roadmap.
The exact scope should be aligned with the investment thesis and the characteristics of the target.
Why is technology due diligence important in M&A?
Technology issues can affect scalability, customer continuity, integration, security, engineering capacity, post-close costs, and the speed at which expected value can be realized.
Technology due diligence helps buyers identify those risks before they become post-acquisition problems.
How is technology due diligence different from financial due diligence?
Financial due diligence focuses primarily on the financial condition, performance, and economics of the business.
Technology due diligence examines whether the technology assets, systems, engineering capabilities, and technical foundations can support current operations and future business objectives.
Both perspectives may influence the overall investment decision.
When should technology due diligence begin in an M&A transaction?
Technology diligence should begin early enough for material findings to influence the transaction and post-close planning.
The exact timing depends on access, transaction structure, target complexity, and the broader diligence process.
What technology risks can affect an M&A deal?
Material risks may include severe cybersecurity exposure, major technical debt, unsupported technology, scalability limitations, integration complexity, weak data foundations, key-person dependencies, and technology capabilities that cannot support the investment thesis.
How should buyers prioritize technology due diligence findings?
Findings should be prioritized according to their materiality to the transaction rather than technical severity alone.
Investors should focus on issues that could influence the investment thesis, scalability, customer continuity, security, engineering capacity, integration, post-close investment, or value-creation timeline.
Can technology due diligence support post-acquisition planning?
Yes. A strong diligence assessment can identify immediate remediation priorities, first 100-day initiatives, and longer-term modernization opportunities.
This allows diligence findings to become an early input into the post-close technology roadmap.
