Managing National Security Risks in M&A: A 2026 Guide
Most businesses view M&A as a pathway to growth and market dominance. However, as of May 2026, a critical, often underestimated, factor looms large: national security risks. These risks can derail even the most promising transactions, leading to significant financial losses, reputational damage, and regulatory penalties.
Last updated: May 8, 2026
Key Takeaways
- National security considerations in M&A have intensified globally, impacting deal approval timelines and structures.
- Key risk areas include technology transfer, data security, critical infrastructure, and geopolitical influence.
- Thorough due diligence, including specialized national security assessments, is essential for identifying and mitigating these risks.
- Regulatory bodies worldwide, like CFIUS in the US, are increasingly scrutinizing transactions for national security implications.
- Proactive engagement with regulators and strong compliance frameworks are vital for successful deal completion.
The Evolving Threat Landscape for M&A
The global geopolitical climate, characterized by heightened tensions and technological competition, has significantly amplified the importance of managing national security risks in M&A. As of 2026, governments are more vigilant than ever about transactions that could potentially compromise their national interests, economic stability, or defense capabilities.
This increased scrutiny is not limited to defense or aerospace sectors. It now extends to areas like artificial intelligence, semiconductors, biotechnology, and critical infrastructure – sectors vital for economic competitiveness and national security. A deal involving a company with advanced AI capabilities, for instance, could attract intense review if the acquiring entity is perceived as a geopolitical rival.
A stark example from early 2026 involved a proposed acquisition of a European semiconductor firm by an Asian conglomerate. While commercially sound, the deal faced immediate opposition due to concerns over technology transfer and potential access to sensitive intellectual property by a state-backed entity. The transaction was eventually renegotiated with stringent conditions on data access and future R&D collaboration.
Identifying Key National Security Risk Vectors
Understanding the specific types of national security risks is the first step in effectively managing them. These risks can manifest in various forms, often intertwined and complex.
Technology Transfer and Intellectual Property Safeguarding
The transfer of sensitive technologies or intellectual property (IP) to foreign entities is a primary concern. This is particularly true for dual-use technologies that have both civilian and military applications. Governments worry that such transfers could bolster the capabilities of potential adversaries.
For example, consider a US-based cybersecurity firm developing advanced encryption algorithms. If acquired by a company with ties to a nation deemed a strategic competitor, regulators would scrutinize the potential for that technology to be compromised or misused. The risk here is not just financial loss for the seller, but a direct threat to national cybersecurity infrastructure.
Data Security and Privacy Concerns
In an era of big data, the control and protection of sensitive personal, corporate, and governmental data are paramount. M&A transactions that involve the transfer of large datasets, especially those containing personally identifiable information (PII) or classified government data, can trigger national security reviews.
A hypothetical scenario: a European cloud services provider, holding extensive data for national governments and critical infrastructure operators, is targeted for acquisition by a non-EU entity. Regulators would intensely probe the acquiring company’s data handling practices, cybersecurity protocols, and any potential influence by a foreign government on data access. The risk lies in potential data breaches or unauthorized access that could undermine public services or national security operations.
Critical Infrastructure and Essential Services
Companies operating in sectors deemed critical to national infrastructure – such as energy, telecommunications, water, transportation, and healthcare – are under particular scrutiny. Acquisitions that could grant foreign entities control over essential services raise immediate national security flags.
In late 2025, a proposed acquisition of a regional energy grid operator in North America was halted due to concerns that the foreign acquirer might not adequately prioritize national energy security during times of crisis. The argument was that control of essential services must remain with entities demonstrably committed to national interests.
Geopolitical Influence and State-Backed Entities
Transactions involving state-backed enterprises or entities with close ties to foreign governments are often viewed with suspicion. The concern is that such acquisitions might be driven by strategic geopolitical objectives rather than purely commercial interests, potentially leading to undue influence or control over key industries.
A recent report highlighted how state-backed investment funds are increasingly using M&A to acquire strategic assets in Western economies. This necessitates rigorous due diligence to ascertain the true nature of the acquirer and their ultimate beneficial owners, as well as any potential obligations they may have to their home governments.
Navigating the Regulatory Maze: CFIUS and Global Equivalents
Regulatory bodies responsible for national security reviews are becoming more assertive and their processes more complex. In the United States, the Committee on Foreign Investment in the United States (CFIUS) is the primary body responsible for reviewing M&A transactions for national security risks.
The CFIUS Review Process
CFIUS reviews transactions involving foreign investment in U.S. businesses that could result in control of such a business by a foreign person where that control might impair the national security of the United States. As of 2026, CFIUS has expanded its jurisdiction and actively scrutinizes a broader range of transactions, including those involving critical technology, critical infrastructure, and sensitive personal data.
The process typically involves a voluntary notice filing, followed by an initial review period. If national security concerns are identified, the review can extend to a formal investigation, potentially leading to mitigation agreements, conditions on the transaction, or even prohibition. Recent trends show an increase in mitigation agreements, requiring parties to implement specific security measures or divest certain assets. For instance, a foreign acquisition of a U.S. software company involved a stringent agreement to isolate the U.S. operations and data from the parent company’s foreign headquarters.
Global Counterparts and Harmonization Efforts
Other countries have established similar bodies to screen foreign investments based on national security grounds. Examples include the Committee on Foreign Investment and National Security (COFINS) in France, the Foreign Investment Review Board (FIRB) in Australia, and increasingly strong review mechanisms in the UK, Canada, Japan, and the EU member states.

While processes vary, there’s a growing trend towards international cooperation and information sharing among these bodies. This means a transaction might be scrutinized by multiple jurisdictions simultaneously, requiring a coordinated compliance strategy. The challenge for businesses is to handle these diverse and often overlapping regulatory landscapes.
Best Practices for Managing National Security Risks in M&A
Proactive and complete risk management is key to successfully closing deals in the current environment. It requires a multi-faceted approach, integrating national security considerations from the earliest stages of deal assessment.
Early and Ongoing Due Diligence
National security due diligence should not be an afterthought. It must be integrated into the initial assessment phase of any potential M&A transaction, especially those with cross-border elements or involving sensitive sectors. This involves:
- Identifying the nationality and ownership structure of the target and acquirer.
- Assessing the nature of the target’s business, particularly its role in critical sectors or its use/development of sensitive technologies.
- Evaluating the target’s data handling practices and the location and security of its data centers.
- Understanding any existing government contracts or sensitive relationships the target may have.
A strong due diligence process can uncover potential red flags early, allowing deal teams to assess the likelihood and severity of regulatory intervention. For example, discovering that a target company has unique access to sensitive government data could immediately trigger a higher level of regulatory risk.
Engaging Specialized Expertise
Navigating the complexities of national security reviews requires specialized knowledge. Companies should engage legal counsel and consultants with expertise in foreign investment review, national security law, cybersecurity, and specific industry regulations.
These experts can help assess potential risks, prepare necessary filings, liaise with regulatory agencies, and develop mitigation strategies. For instance, a technology M&A deal might require experts who understand export control regulations (like ITAR or EAR in the U.S.) and how they might impact the transaction and future operations.
Developing Proactive Mitigation Strategies
If potential national security risks are identified, developing proactive mitigation strategies is crucial. These can include:
- Structural modifications to the deal, such as agreeing to minority stakes instead of full control, or establishing ring-fenced operations.
- Committing to specific operational safeguards, such as data localization, enhanced cybersecurity measures, or restrictions on technology transfer.
- Obtaining pre-clearance or engaging in informal discussions with relevant regulatory bodies to gauge their concerns.
A common mitigation strategy involves creating a “clean team” within the acquired U.S. entity, completely separated from the foreign parent’s management and data systems, to handle sensitive technologies or data. This demonstrates a commitment to safeguarding national interests.
Building Strong Compliance Frameworks
For companies operating in sensitive sectors or engaging in frequent cross-border M&A, establishing a strong internal compliance framework is essential. This framework should:
- Embed national security risk assessment into the M&A due diligence checklist.
- Provide clear guidelines for employees on handling sensitive information and technologies.
- Include regular training on national security compliance requirements.
- Establish protocols for reporting and addressing potential security breaches or regulatory concerns.
A strong compliance culture not only helps avoid regulatory pitfalls but also enhances the company’s reputation as a responsible global operator.
Real-World Implications and Case Studies
The impact of national security concerns on M&A is not theoretical; it has tangible consequences. As of May 2026, several high-profile deals have been significantly altered or blocked due to these considerations.
The China-Meta Manus Deal: A 2026 Example
In early 2026, China’s regulatory bodies blocked Meta’s proposed acquisition of Manus, a deal that would have expanded Meta’s presence in the virtual reality and AI sectors. The stated reasons, while not exclusively national security, touched upon data control, intellectual property, and the potential for foreign influence in a strategically important technology field. (Source: Lexology, 2026)
This case illustrates how concerns about data privacy, technological advancement, and geopolitical alignment can intersect to prevent M&A transactions, even for major global players. It underscores the need for acquirers to understand the specific national security priorities of the target country’s government.
Cross-Border M&A: The Dealbreaker Factor
National security has emerged as a major dealbreaker in cross-border M&A. According to industry analyses from early 2026, a growing percentage of deal failures or significant renegotiations can be attributed to national security reviews. This trend is particularly pronounced in sectors like advanced technology, telecommunications, and biopharmaceuticals.
For example, a U.S. firm looking to acquire a Canadian company specializing in quantum computing faced significant hurdles. The U.S. government’s concern centered on the potential for quantum computing breakthroughs to be leveraged for advanced encryption or decryption, posing a direct national security threat if controlled by a rival nation’s acquirer. The deal was eventually approved only after the acquirer agreed to stringent conditions on data access and technology development, effectively limiting its ability to fully integrate the acquired technology.
Common Pitfalls to Avoid
Despite the increased awareness, companies still fall into common traps when managing national security risks in M&A.
Underestimating Regulatory Scrutiny
A significant pitfall is assuming that a transaction will fly under the radar of national security reviews, particularly for deals that don’t appear to be in traditional defense sectors. Many companies underestimate the breadth of technologies and industries now considered critical.
The solution is to conduct a thorough assessment of the target company’s operations against current national security priorities. This includes looking beyond direct product applications to consider the underlying technology, data generated, and supply chain vulnerabilities.
Delayed Engagement with Regulators
Waiting until the formal review process begins to engage with regulators is a common mistake. Proactive engagement, even informal discussions at an early stage, can provide valuable insights into potential concerns and help shape the transaction structure or mitigation plans.
Companies should aim to understand the regulatory appetite for a particular deal as early as possible, ideally before signing definitive agreements. This proactive approach can save considerable time and resources down the line.
Inadequate Due Diligence Scope
Confining due diligence solely to financial and commercial aspects without a dedicated national security component is another major error. This can lead to unexpected roadblocks during the regulatory review phase.
The solution is to incorporate specific national security diligence questions into the standard M&A checklist, or to commission a specialized national security diligence report for transactions that warrant it.
Expert Insights and Future Trends for 2026 and Beyond
The world of national security risks in M&A is dynamic and continues to evolve. As of May 2026, several trends are shaping the future.
Increased Focus on Supply Chain Resilience
Geopolitical instability has heightened concerns about the security and resilience of global supply chains. M&A transactions involving companies with complex or foreign-dependent supply chains will face greater scrutiny regarding potential disruptions or vulnerabilities.
This means acquirers must not only assess the target’s business but also its entire ecosystem. Understanding where components are sourced, manufactured, and transported will be critical for regulatory approval.
The Growing Role of AI and Emerging Technologies
Artificial intelligence, quantum computing, biotechnology, and advanced materials are increasingly central to national security strategies. Deals involving companies at the forefront of these fields will attract the most intense regulatory attention.
Regulators are developing more sophisticated methods to assess the national security implications of these latest technologies, including their potential for dual-use applications or contribution to an adversary’s technological advantage.
Harmonization and Divergence in Global Regulations
While there are efforts toward international cooperation, differing national priorities can lead to divergent regulatory approaches. Companies operating globally must be prepared for a patchwork of regulations, requiring tailored strategies for each jurisdiction.
The trend toward “investment screening” beyond traditional national security is also growing, encompassing economic security and resilience. This broader scope means more transactions may fall under regulatory review.
Proactive Compliance as a Competitive Advantage
In this environment, companies that master the art of managing national security risks in M&A will gain a competitive advantage. Those who can Handle the regulatory landscape efficiently, demonstrate strong compliance, and proactively address concerns are more likely to close deals successfully and build trust with governments.
