Overview of Mergers and Acquisitions Law in the USA
M&A activity in the USA is shaped by a complex interplay of federal and state statutes, case law, stock exchange rules, and industry-specific mandates. Unlike the UAE’s Federal Decree-Law No. 32 of 2021 on Commercial Companies—which codifies many M&A principles—the US relies on a hybrid system. Core legal requirements span antitrust law, securities regulation, tax, and sectoral controls, with additional focus on the growing importance of cross-border anti-corruption compliance as per federal initiatives.
Recent Developments and Relevance to UAE Businesses
Since 2022, the US has enhanced scrutiny of foreign investments, introduced stricter regulatory timelines, and prioritized data security. For UAE firms, this means additional diligence and documentation—to satisfy both US regulators (notably CFIUS and the SEC) and UAE mandates for transaction transparency and anti-money laundering, supported by resolutions under UAE Cabinet Decision No. 10 of 2019.
Key Legal Frameworks and Regulatory Authorities
Primary Legal Sources
| Regulation | Scope | Application for UAE Parties |
|---|---|---|
| Securities Exchange Act of 1934 | Disclosure, trading, and tender offers for public companies | Triggers SEC review and mandatory filings if acquiring US-listed companies |
| Hart-Scott-Rodino (HSR) Antitrust Improvements Act | Pre-merger notification and waiting period for certain transactions | Requires advance clearance for qualifying deals, even with foreign buyers |
| Committee on Foreign Investment in the United States (CFIUS) | National security review of foreign investments | Specific focus for UAE government-backed or strategic acquisitions |
| State Corporate Laws (e.g., Delaware General Corporation Law) | Board duties, shareholder approval, procedural governance | Governs private company deals, especially Delaware-incorporated targets |
Regulators and Their Roles
The US Securities and Exchange Commission (SEC) oversees securities offerings, disclosures, and antifraud provisions, while the Department of Justice (DOJ) and Federal Trade Commission (FTC) approve or block deals on antitrust grounds. CFIUS, an interagency body, reviews certain foreign investments for threats to national security. For UAE acquirers, understanding these regulators’ mandates is crucial to avoiding compliance pitfalls.
Due Diligence and Disclosure Requirements
Key Stages of Due Diligence
Due diligence underpins legal risk assessment and valuation in any US-target M&A. For UAE buyers, several layers of diligence are essential:
- Corporate Structure and Governance: Scrutinize shareholder agreements, bylaws, and board minutes.
- Financial Records: Audit financial statements to US GAAP standards.
- Regulatory Compliance: Assess US federal, state, and industry-specific obligations, especially under the Foreign Corrupt Practices Act (FCPA) and relevant UAE anti-money laundering laws.
- Employment and IP Exposure: Inventory key assets and potential disputes.
- Cybersecurity and Data Privacy: Evaluate exposure under the California Consumer Privacy Act (CCPA) and potential implications post-deal.
Disclosure and Filing Obligations
US law distinguishes between private and public company disclosures, but both require material information be truthfully and transparently shared. Public company deals require prompt SEC filings (e.g., Form 8-K, Schedule TO for tender offers), including details about the deal terms, financing sources, and identities of major stakeholders—including foreign acquirers. UAE acquirers must ensure all cross-border documentation reflects both US and relevant UAE regulatory requirements.
Foreign Investment Restrictions and CFIUS Review
CFIUS Mandate and Scope
The Committee on Foreign Investment in the United States (CFIUS), governed by section 721 of the Defense Production Act of 1950 and updated by the Foreign Investment Risk Review Modernization Act (FIRRMA) of 2018, reviews and potentially blocks foreign M&A transactions that may affect US national security. Transactions with UAE sovereign or strategic interests—particularly in tech, infrastructure, and data-centric industries—face heightened CFIUS scrutiny.
Mandatory vs Voluntary Filings
| Filing Type | 2022–2025 New Requirements | Comparison to Previous Guidelines |
|---|---|---|
| Mandatory Declared Filings | Expanded to include critical technology, sensitive data, and infrastructure | Previously, more limited to defense-related assets |
| Voluntary Notice | Recommended for any potentially sensitive deal | No formal obligation, but growing adoption post-FIRRMA |
Practical Consultancy Insight
UAE buyers should conduct an early, robust CFIUS screening and submit voluntary notices for ambiguous deals. Early engagement with CFIUS advisors and US counsel can flag potential “national security” touchpoints—such as data access or critical supply chains—and pre-empt costly delays or retroactive interventions.
Example Scenario
Case Study: A UAE sovereign fund acquires a controlling interest in a US technology company handling sensitive military data. CFIUS investigates, requiring the fund to restructure the deal, ring-fence sensitive business units, and implement US-based data access protocols as a condition of approval.
Antitrust Regulations and Competition Law
Hart-Scott-Rodino (HSR) Act: Thresholds and Process
Under the HSR Act (15 U.S.C. § 18a), parties to certain large M&A transactions must make pre-merger filings and observe a waiting period. The FTC and DOJ may request further information or halt deals that threaten to substantially lessen competition. The law applies even to foreign entities if the target company or assets meet US “commerce” thresholds, which are adjusted annually. HSR compliance is especially relevant for UAE conglomerates and sovereign-owned investors eyeing major US sectors.
2022–2025 Updates and Trends
- Lowered Notification Thresholds: Many more deals now require HSR filings.
- More Rigorous Enforcement: Focus on nascent and digital market competition, not just traditional sectors.
- Prolonged Review Timelines: Complex or “vertical” deals face greater risk of delay and intervention.
Comparison Table: Old vs New HSR Rules
| Year | Notification Threshold | Average Review Period |
|---|---|---|
| Pre-2022 | USD 94 million | 30–45 days |
| 2022-2025 | USD 111.4 million | 45–90 days (complex deals longer) |
Securities Laws in Public M&A Transactions
SEC Rules for Tender Offers and Proxy Statements
Public M&A deals—such as tender offers or mergers with US-listed companies—must comply with the Exchange Act of 1934, SEC Rule 14d-1 et seq., and the rules of major stock exchanges (NYSE, NASDAQ). UAE acquirers must structure offers to satisfy US antifraud, anti-manipulation, and fairness standards. Filings (e.g., Schedule TO, Schedule 13D) must be comprehensive, truthful, and timely.
Foreign Private Issuer Considerations
While “foreign private issuers” (including UAE-based firms) gain certain SEC reporting exemptions, missteps—such as untimely or inaccurate disclosures—can trigger enforcement actions or bar future US listings.
Practical Guidelines for UAE Inbound Deals
- Partner with US counsel early to align disclosure content and timing.
- Coordinate with UAE supervisory authorities to ensure transaction transparency, as expected under UAE Cabinet Resolution No. 58 of 2020 (Ultimate Beneficial Ownership Regulation).
Employment, Intellectual Property, and Data Implications
Employee Rights and Contract Transfers
The transfer of employees in US M&A is governed by a mix of federal, state, and local law (notably COBRA, WARN Act, and discrimination statutes). UAE acquirers should anticipate:
- Advance notice requirements under the Worker Adjustment and Retraining Notification (WARN) Act for large layoffs.
- Potential assumption or renegotiation of benefit plans and labor agreements.
Intellectual Property Transfers
IP assets—core to many US targets—must be protected through assignment agreements, recording of assignments with the US Patent and Trademark Office, and post-closing diligence to assure title. GCC investors are recommended to map patent, trademark, and software assets, reconciling these with UAE IP holdings under Federal Decree-Law No. 11 of 2021 (UAE Trademarks Law).
Data Privacy and Cybersecurity
The US has robust data transfer requirements, especially when personal data held in the US may be accessed from abroad. The expansion of CCPA and growing sectoral compliance mandates (including healthcare, finance, and telecommunications) require UAE buyers to integrate parallel data-mapping exercises as performed under UAE Federal Decree Law No. 45 of 2021 on Data Protection.
Compliance Risks and Strategies for UAE Businesses
Key Compliance Risks in US M&A
- Regulatory Delays: Failure to file or incomplete filings can result in significant transaction delays or penalties.
- CFIUS Blockage or Remediation: Retrospective CFIUS review could unwind or severely condition a transaction post-closing.
- Antitrust Suits: Both US authorities and third parties can seek injunctive relief or damages.
- Securities Law Violations: Inaccurate disclosures may lead to SEC enforcement, private litigation, or reputational damage.
- Employment or Data Compliance Breaches: Back-end liabilities may surface if transitional protocols are lax.
Proactive Compliance Strategies
- Conduct early-phase regulatory due diligence encompassing both US and UAE obligations.
- Segment transaction teams to manage CFIUS, antitrust, and employment/IP reviews independently.
- Obtain pre-deal clearances or no-action letters when ambiguity exists.
- Develop rigorous data transfer, cybersecurity, and anti-bribery protocols tailored to both regimes.
- Maintain ongoing dialogue with UAE authorities, updating Ultimate Beneficial Owner registries in line with Cabinet Resolution No. 58 of 2020.

Case Studies and Practical Examples
Case Example 1: CFIUS-Conditioned Approval
A UAE-based investment firm targeted a US semiconductor manufacturer. CFIUS imposed hold-separate requirements and insisted on minority, non-controlling rights to avoid downstream access to sensitive US technologies—delaying the closing by 6 months, but ultimately preserving the deal’s value with enhanced compliance undertakings.
Case Example 2: Securities Law Penalties for Incomplete Disclosures
A UAE investor missed a required Schedule 13D amendment following a stake increase in a US biotech company. The SEC initiated enforcement, resulting in a negotiated penalty and public censure—underlining the need for integrated deal teams and ongoing monitoring, even after a transaction closes.
Practical Lessons for UAE Companies
- Initiate parallel US-UAE legal reviews of deal documentation.
- Assign a compliance officer to manage post-closing risk updates.
- Establish clear escalation protocols for regulatory queries or legal reviews in both jurisdictions.
Conclusion and Strategic Best Practices
For UAE-based organizations, mastering the legal requirements impacting US M&A deals is no longer a mere compliance exercise—it is a strategic imperative. Increased cross-border regulatory alignment, stricter US foreign investment controls, and the UAE’s own evolving transactional transparency standards mean that legal teams must act early, plan thoroughly, and integrate cross-jurisdictional expertise from the outset of any US-facing transaction.
Key takeaways include:
- Advance CFIUS and HSR planning is essential for smooth execution of deals with US targets.
- Integrated, multidisciplinary teams—combining legal, compliance, HR, and IT—are vital for effective diligence and regulatory navigation.
- Transparent, truthful cross-jurisdictional disclosure is not optional—it must be embedded in all deal workflows.
- Ongoing post-closing monitoring safeguards business continuity and reputation.
Looking ahead, continued regulatory convergence between the UAE and the US will require businesses to stay informed and proactively adapt their compliance programs. Engaging with experienced legal advisors—versed in both US and UAE regulatory nuances—remains the most effective measure for ensuring legal certainty and transactional success in the years ahead.
