Introduction
Technology due diligence is a structured evaluation of the target company's technology assets, capabilities, risks, and liabilities that goes far beyond the financial and legal due diligence conducted in non-TMT transactions. In a pharmaceutical acquisition, the value proposition is the drug pipeline and regulatory approvals. In a TMT acquisition, the value proposition is often the technology itself: the codebase, the intellectual property, the engineering team, and the platform architecture. Technology integration issues account for approximately 30% of failed mergers (according to Deloitte research), and 62% of deals miss their financial targets primarily because of poor due diligence (KPMG). For TMT investment bankers, understanding the key areas of technology due diligence is essential because findings directly affect deal valuation, structure, and post-close integration planning.
Intellectual Property Assessment
IP due diligence examines the target's portfolio of patents, trademarks, copyrights, trade secrets, and unregistered intellectual property to verify ownership, assess enforceability, and identify risks.
- Core IP Due Diligence Components
Ownership and chain of title: Verify that the target actually owns the IP it claims. This requires reviewing assignment agreements from employees and contractors (ensuring all code was developed as "work for hire" or under valid IP assignment), confirming that former employer IP was not incorporated into the target's products, and checking for joint ownership or co-development arrangements that may limit the target's control over certain IP. Enforceability: Assess whether patents are valid, whether trade secrets have been adequately protected (through NDAs, access controls, and documentation), and whether trademarks are properly registered and maintained. Infringement risk: Evaluate whether the target's products infringe third-party patents (freedom-to-operate analysis) and whether the target faces pending or threatened litigation. Patent trolls (non-practicing entities) are particularly active in software and telecommunications, and a target's exposure to NPE litigation can represent significant contingent liabilities. Licensing obligations: Review all inbound IP licenses to ensure the target has the right to use third-party technology, and assess whether these licenses are transferable in an M&A transaction (some licenses include change-of-control provisions that could be triggered by the acquisition).
With AI products increasingly incorporating hundreds of patents, copyrights, and trade secrets in a single offering, IP due diligence has become more complex. AI-specific considerations include the ownership of training data (was it properly licensed?), the IP status of AI-generated outputs, and whether the target's AI models were trained on copyrighted content that could create infringement exposure.
Code Quality and Technical Debt
Code quality assessment examines the codebase's architecture, coding standards, test coverage, documentation, and deployment practices. Key indicators include automated test coverage (mature engineering organizations maintain 70-80%+ test coverage), code review practices, CI/CD (continuous integration/continuous deployment) pipeline maturity, and the frequency and quality of releases. A codebase with minimal test coverage, inconsistent coding standards, and manual deployment processes presents integration risk that should be reflected in deal pricing.
Platform scalability is a closely related assessment. The due diligence team evaluates whether the target's architecture can support the growth assumptions in the deal model: if the acquirer is paying a premium based on projections that the platform will scale from 10,000 to 100,000 enterprise users, the architecture must be capable of handling that load without a fundamental rewrite. Key scalability indicators include database architecture (monolithic vs. distributed), cloud infrastructure design (single-region vs. multi-region), API throughput limits, and the target's track record of handling traffic spikes. For cross-border acquirers, data residency requirements in the EU, UK, and Asia-Pacific may necessitate architectural changes to comply with local regulations, adding to post-close integration costs.
Open-Source Software Compliance
Cybersecurity and Data Infrastructure
Cybersecurity due diligence evaluates the target's security posture, including vulnerability management, access controls, incident response capabilities, and compliance with industry standards (SOC 2, ISO 27001). IBM's 2024 Cost of a Data Breach Report found the global average cost of a data breach reached $4.88 million, with technology sector breaches averaging higher due to the sensitivity of customer data and intellectual property involved. A target with a history of data breaches, unpatched security vulnerabilities, or inadequate access controls presents both financial risk (remediation costs, regulatory fines, customer notification expenses) and reputational risk that can permanently damage the acquirer's brand and customer relationships. Data privacy regulations (GDPR, CCPA) create additional due diligence requirements: the acquirer must assess whether the target's data collection, processing, and storage practices comply with applicable privacy laws, and whether the acquisition itself triggers consent requirements or data transfer restrictions.
The technology due diligence process typically takes 2-4 weeks for a mid-market transaction, with more complex targets (multiple products, legacy systems, international operations) requiring longer timelines. The assessment is typically conducted by a combination of the acquirer's engineering team, external technical due diligence firms, and specialized IP counsel.
