Designing Hell or High Water Clauses for Foreign Investment Clearances

Anvil

Foreign direct investment screening statutes across major industrial jurisdictions hand regulatory agencies sweeping authority to block cross-border acquisitions on national security grounds. Sellers want absolute certainty that an executed purchase agreement will reach closing, while buyers naturally resist taking on unquantified obligations to restructure global operations or sell off core intellectual property just to satisfy sovereign regulators. How regulatory approval covenants are drafted determines which party absorbs the economic loss when government intervention delays, conditions, or prohibits a transaction.

Standard merger agreement covenants built around commercial reasonableness simply fail to protect sellers when national security agencies demand structural concessions.

In cross-border M&A involving dual-use technology, critical infrastructure, or sensitive personal data, foreign investment approvals present structural hurdles very different from traditional antitrust clearances. Antitrust enforcement relies on defined market concentration metrics. Foreign investment reviews, by contrast, operate under broad, non-justiciable statutory mandates where national security considerations override ordinary commercial logic.

When a purchase agreement obligates a buyer to secure regulatory clearance without bounding the required remedies, the buyer effectively gives the seller a blank check backed by its own corporate assets.

Obligation Floor in Regulatory Allocations

Merger agreements allocate regulatory risk on a spectrum ranging from passive cooperate-and-file covenants to unconditional commitments. A baseline covenant requires the buyer to make standard filings and supply supplemental information requested by government agencies. This minimal allocation leaves the buyer free to abandon the transaction if regulatory bodies demand divestitures or operational restrictions as a condition of approval.

Sellers facing substantial interim operating risks or financing expiration dates rarely accept this setup.

To bridge the gap, target companies demand hell or high water covenants. In its purest form, a hell or high water provision obligates the acquiring entity to take any and all steps necessary to eliminate regulatory impediments and obtain foreign investment clearance before the outer drop-dead date. That unconditional obligation can force the buyer into severe structural remedies: selling target or buyer assets, licensing technical know-how to domestic competitors, terminating supply arrangements with overseas affiliates, or accepting governance restrictions that strip foreign board representation.

Without explicit financial limits or operational carveouts, an unconditional covenant forces the buyer to degrade its existing corporate structure to complete the deal.

A buyer accepting an unqualified obligation to divest assets faces an average closing delay of eleven months when national security agencies demand structural remedies.

When national security reviewers identify unmitigable risks, no contractual commitment between private entities can force a sovereign government to issue a clearance certificate. The hell or high water clause functions as an economic risk-shifting mechanism, establishing that if government opposition renders the transaction impossible, the buyer remains liable for breach of covenant or must pay a stipulated reverse termination fee. Parties routinely litigate whether a buyer actually fulfilled its contractual duty to fight regulatory opposition before claiming that approval proved impossible to obtain.

Does Reasonable Best Efforts Deliver Security Clearance?

Litigation records from state regulatory review proceedings show that intermediate effort standards grant buyers wide discretion to abandon deals. Statutory standards such as reasonable best efforts or commercially reasonable efforts carry implicit financial boundaries. Courts interpreting Delaware and English contract law treat reasonable best efforts as requiring significant diligence, yet excuse performance when compliance demands steps that would fundamentally alter the deal’s economic assumptions.

A buyer operating under a reasonable best efforts covenant can refuse to divest a profitable business line, citing the disproportionate impact on its overall business valuation.

When negotiating these commitments, the seller demands absolute coverage while the buyer attempts to carve out unanticipated national security conditions. In cross-border tech transactions, buyers frequently agree to reasonable best efforts subject to a material adverse effect qualifier applied specifically to the required regulatory remedies. Under this structure, the buyer must accept minor operational restrictions ~ like localized data residency commitments or isolated compliance reporting ~ but retains the right to walk away if an agency demands the sale of core technical assets or the severance of global research facilities.

When an agreement fails to define the boundary between reasonable efforts and mandatory divestitures, the parties invite prolonged litigation during the interim closing period. The seller asserts that any available divestiture falls within the buyer’s obligation to secure closing, while the buyer contends that structural remedies were never contemplated within the purchase price. Precision in drafting requires listing exact remedy thresholds, excluding specific high-value assets from mandatory divestiture schedules, and capping the total economic loss the buyer must endure to satisfy clearance authorities.

• Unbounded Divestment Schedules exposing foreign buyers to forced asset sales without financial floor prices or minimum valuation thresholds.
• Vague Effort Qualifiers relying on generic best efforts language that courts interpret as excusing performance when structural remedies surface.
• Omitted Interlock Rules failing to tie foreign investment clearance triggers to antitrust divestiture caps, creating conflicting contractual duties.
• Uncapped Regulatory Delays allowing statutory review clocks to run past debt financing commitment dates without compensating ticking fees.

Drafting choices distinguish between target-side divestitures and buyer-side asset sales. A buyer may agree to sell any asset acquired within the target enterprise to secure clearance, while strictly shielding its pre-existing corporate assets from regulatory modification. That distinction preserves the buyer’s core platform while forcing the target enterprise to bear the structural adjustments required by national security regulators.

Section 6.04(b) of a standardized cross-border purchase agreement illustrates this structural shift: “The Buyer shall take any and all actions necessary to secure all Required Competition Approvals and Foreign Investment Clearances; provided, however, that the Buyer shall not be obligated to agree to any divestiture, hold-separate arrangement, or operational restriction that, individually or in the aggregate, would result in a Material Adverse Effect on the business, financial condition, or results of operations of the Buyer and its Subsidiaries, taken as a whole, excluding for such purpose the Target Enterprise.”

Registry

Filing cross-border transaction documents forces parties to navigate overlapping statutory frameworks with non-harmonized review timelines. National security screening authorities operate under broad administrative mandates that grant regulators unilateral power to suspend review clocks, demand confidential technical filings, and inspect foreign supply chains. Foreign investment clearance mechanisms across key jurisdictions illustrate the complex regulatory matrix buyers must navigate.

Statutory timelines routinely stretch during review. In the United States, the Committee on Foreign Investment in the United States (CFIUS) operates under Section 721 of the Defense Production Act of 1950. CFIUS evaluates foreign control and non-controlling investments in US businesses involved in critical technology, critical infrastructure, or sensitive personal data (TID U.S. businesses).

A standard CFIUS review sequence begins with a 45-day assessment period following formal declaration or notice acceptance, followed by an optional 45-day investigation phase. If CFIUS identifies unmitigated national security risks, it may grant a extraordinary 15-day extension or refer the transaction to the President for a final 15-day determination period.

Statutory Clocks and Mandatory Filing Triggers

Foreign direct investment screening statutes across Europe and Asia create distinct procedural hurdles that run parallel to antitrust filings. In the United Kingdom, the National Security and Investment Act 2021 (NSIA) establishes a mandatory notification regime across 17 specified sensitive sectors, including artificial intelligence, quantum technologies, synthetic biology, and advanced materials. The UK Investment Security Unit (ISU) conducts an initial 30-working-day assessment.

If the Secretary of State issues a call-in notice, the ISU enters a 30-working-day detailed assessment phase, extensible by an additional 45 working days.

In Germany, foreign investment reviews fall under the Foreign Trade and Payments Act (AWG) and the Foreign Trade and Payments Ordinance (AWV). The Federal Ministry for Economic Affairs and Climate Action (BMWK) conducts cross-sectoral reviews for non-EU/EFTA investors acquiring 25% or more of voting rights, alongside sector-specific reviews for military and dual-use acquisitions starting at 10% voting rights. The German framework imposes a two-month initial assessment phase, followed by a four-month formal investigation that pauses whenever the Ministry requests additional documentation from foreign parties.

The European Union FDI Screening Framework (Regulation 2019/452) establishes a cooperation and information-sharing mechanism among EU member states. Individual member nations retain ultimate approval authority over foreign investments within their borders, but the framework allows the European Commission and other member states to issue formal opinions on transactions affecting national security or critical projects of Union interest. This intra-EU mechanism introduces informal delays into national screening processes, extending domestic statutory clearance timelines by weeks.

Singapore introduced the Significant Investment Review Act (SIRA), establishing a national security screening regime for designated entities holding critical national security functions. SIRA grants designated competent authorities powers to review ownership changes, board appointments, and operational restructurings of critical Singapore businesses, mirroring CFIUS and NSIA screening mechanics in Southeast Asian deal structures.

National Security Mitigation Machinery

When regulatory authorities identify potential threats to critical infrastructure or sensitive personal data, clearance often hinges on negotiated behavioral or structural constraints. Regulators enforce compliance through formal National Security Agreements (NSAs) or Security Control Agreements (SCAs). These mitigation agreements force foreign buyers to alter corporate governance structures, restrict data access, and isolate domestic operations from parent company oversight.

Standard mitigation requirements demand establishing dedicated security committees within the target board, composed exclusively of cleared citizens approved by the screening agency. Foreign parent entities must surrender direct operational oversight over sensitive technology divisions, granting the independent security committee sole authority over capital expenditures, hiring decisions, and IP licensing within the target country. These governance carveouts can severely undermine the strategic rationale for cross-border integration.

1. Formal execution of preliminary joint submission forms detailing ultimate beneficial ownership, global supply chain dependencies, and sovereign government funding sources.
2. Engagement with agency case officers during initial assessment windows to address preliminary national security inquiries and technical audit requests.
3. Submission of structured mitigation proposals, including corporate governance isolation plans, data residency commitments, and restricted facility access schedules.
4. Negotiation of binding National Security Agreements, Security Control Agreements, or Proxy Agreements with foreign investment regulatory authorities.
5. Receipt of formal regulatory clearance orders or presidential approval decisions confirming final completion of statutory screening protocols.

Legal counsel often conflate merger control commitments with foreign investment screening obligations. While antitrust authorities seek to restore market competition through predictable commercial remedies, foreign investment reviewers focus on defense readiness, intelligence exposure, and supply chain vulnerability. A remedy acceptable to antitrust regulators may fail to address national security concerns raised during parallel investment reviews.

A corporate development VP at an overseas technology acquirer summarized the statutory friction succinctly: “The screening agency insisted on an independent security board with sole power over product roadmaps, leaving us with financial ownership of a target business we were legally prohibited from managing.”

Divestment

Negotiating regulatory approval commitments forces transaction partners to confront the operational consequences of severe structural remedies. When national security regulators determine that behavioral mitigation measures cannot adequately insulate national interests, they condition transaction clearance on structural divestitures. Structural remedies require selling designated business lines, manufacturing plants, software repositories, or patent portfolios to approved third-party purchasers before or after transaction closing.

How divestment commitments are designed determines whether an acquisition retains its commercial value or degenerates into an asset-stripping exercise. Where a hell or high water clause requires a buyer to accept any structural remedy demanded by government regulators, the buyer effectively transfers asset pricing risk to an administrative agency whose single mandate is risk elimination rather than economic efficiency.

Structural Remedies and Asset Severance

Regulatory demands that require selling operational divisions or carving out proprietary software code transform acquisition economics. Carving out a technology platform requires severing integrated codebases, splitting shared research and development personnel, and transferring manufacturing license rights. This process generates substantial friction, eroding scale economies and creating operational dependencies between the retained target business and the divested entity.

Structural remedies that force the severance of core intellectual property degrade target enterprise valuation faster than delayed closing dates.

When a government mandate requires divesting sensitive assets, the sale occurs under distressed conditions. Market buyers recognize that the seller operates under a statutory deadline to close the divestiture or risk losing the primary cross-border transaction. Third-party acquirers exploit this leverage with heavily discounted purchase prices, knowing the primary buyer must complete the disposition to satisfy its hell or high water commitment.

In a cross-border semiconductor acquisition, the buyer agreed to divest three fabrication lines to secure antitrust clearance. The foreign investment screening review subsequently mandated the complete severance and sale of the associated process architecture patent portfolio to a domestic competitor. The buyer incurred a 42% valuation write-down on the acquired target assets within six months of closing, directly attributable to the forced structural divestiture mandated by government security reviewers.

Governance Isolation and Operational Hold Separate Orders

National security agencies routinely impose interim measures while evaluating cross-border technology acquisitions. Hold separate orders require the acquiring entity to maintain the target business as a distinct, fully independent commercial enterprise during the review period. The buyer cannot integrate operations, access target technical data, consolidate financial reporting, or alter target management structures until regulators grant final clearance.

When interim hold separate orders extend past original target operational integration timelines, buyers incur significant holding costs. Duplicate management teams, standalone administrative systems, and isolated distribution channels burn cash while preventing the realization of planned transaction synergies. In prolonged review scenarios, interim hold separate mandates undermine target commercial momentum, leading to customer churn and engineering talent loss.

Proxy agreements represent the most severe form of governance isolation. Under a proxy agreement, foreign parent companies transfer total operational control and voting rights of the domestic target business to approved proxy holders. The proxy holders act independently of the foreign parent, holding legal duty to the national security agency rather than the foreign shareholder.

The foreign parent retains economic exposure to the financial performance of the business, but loses all oversight over management decisions, strategic planning, capital investments, and asset dispositions.

• Asset Carveout Thresholds specifying maximum annual revenue or EBITDA percentages of target assets subject to mandatory divestiture commitments.
• Excluded IP Schedules identifying core patent families, proprietary source code, and manufacturing trade secrets strictly exempt from forced licensing or disposition.
• Crown Jewel Trigger Provisions allowing buyers to terminate purchase agreements if regulators mandate selling primary value-generating target divisions.
• Remedial Sale Valuation Floors establishing minimum acceptable sale prices for forced divestitures, shifting remaining losses back to transaction counterparties.

Operating under a proxy agreement or national security mitigation protocol exposes corporate officers to severe statutory penalties for non-compliance. Regulatory authorities mandate regular third-party audits, continuous monitor reporting, and random facility inspections to verify compliance with governance isolation orders. Unintentional data leaks or improper administrative communication between parent company executives and proxy-controlled target management can trigger civil fines exceeding tens of millions of dollars and lead to immediate criminal prosecution of non-compliant executives.

During a contentious cross-border software acquisition, an institutional minority investor reviewed the regulatory mitigation expenses billed to the operating target. The target enterprise spent $14.2 million over eighteen months solely to maintain an independent audit monitor, support dedicated proxy board counsel, and construct isolated cloud computing infrastructure mandated under a CFIUS National Security Agreement. These administrative compliance costs completely erased the target’s operating margins for two consecutive fiscal years.

Trench

Financial mechanisms embedded within transaction documents serve as structural counterparties to legal clearance covenants. When parties allocate foreign investment approval risk, drafting terms alone fails to align incentive structures. Financial commitments, including reverse termination fees, ticking fees, and regulatory expense allocations, force parties to internalize the costs associated with regulatory delays and potential deal failure.

A buyer agreeing to an absolute hell or high water covenant without financial caps exposes its corporate balance sheet to structural degradation. Conversely, a target company agreeing to lock up its operations during a twelve-month regulatory review without financial protection risks severe enterprise impairment if the transaction ultimately fails to secure approval. Financial structuring bridges this operational gap by pricing regulatory risk directly into the transaction mechanics.

Reverse Termination Fee Architecture

Liquidated damages payable upon regulatory failure shift the economic burden of regulatory rejection back to the acquiring party. A regulatory reverse termination fee (RRTF) obligates the buyer to pay a specified cash amount to the seller if the transaction terminates due to failure to obtain required foreign investment clearances prior to the drop-dead date. RRTF amounts in cross-border tech M&A range from 5% to 15% of total enterprise value, substantially exceeding traditional antitrust reverse break fees.

The structure of the RRTF dictates the buyer’s incentive to pursue aggressive regulatory remedies. Where the purchase agreement exposes the buyer to both a high reverse termination fee and an absolute hell or high water obligation, the fee acts as a financial cap on breach of covenant damages. If the cost of complying with an extreme regulatory divestiture mandate exceeds the stipulated fee, the buyer makes a rational commercial calculation to terminate the agreement, forfeit the fee, and absorb the defined financial loss.

Sellers construct RRTF provisions with explicit interlock triggers, ensuring fee payment occurs if clearance fails due to buyer non-compliance with procedural filing duties or failure to accept mandated mitigation measures. Buyers attempt to incorporate fiduciary out carveouts, asserting that if compliance requires taking steps that violate parent board fiduciary duties under home jurisdiction corporate law, the termination fee should be waived or significantly reduced.

Ticking Fees and Closing Date Extensions

Extended statutory review periods erode deal economics through capital lockup and target operational drift. To compensate target shareholders for prolonged interim closing periods, purchase agreements incorporate ticking fee structures. A ticking fee increases the purchase price by an agreed daily or monthly percentage rate for every day the closing extends past a specified benchmark date until foreign investment clearance is secured or the contract reaches its outer termination date.

Ticking fees incentivize buyers to prosecute foreign investment filings with speed and transparency. A standard ticking fee calculates interest based on the overall equity value of the transaction, accruing daily at annualized rates between 4% and 8%. This mechanism offsets the cost of target capital lockup while discouraging buyers from using administrative review periods as strategic stalling tactics when market conditions shift unfavorably during the interim period.

Ticking fee covenants interlock directly with outer drop-dead dates, creating defined financial milestones. Drop-dead provisions grant either party the right to terminate the transaction if regulatory clearances are not obtained within a specified period, typically twelve to eighteen months from signing in complex foreign investment transactions.

1. Explicit definition of regulatory failure events, triggering immediate liability for regulatory reverse termination fees without requirement to prove contractual breach.
2. Establishment of escrow mechanics requiring the foreign buyer to deposit reverse break fee funds into domestic escrow accounts upon initial regulatory notice filing.
3. Tiered ticking fee rate schedules escalating financial accrual amounts as review timelines cross successive 90-day assessment milestones.
4. Fiduciary duty exception carveouts defining conditions under which parent entity boards may refuse extreme structural remedies without forfeiting break fees.

Incorporating ticking fee schedules and defined reverse break fee caps prevents endless administrative extensions that bleed enterprise value. When financial risk is clearly bounded, deal principal legal counsel can assess the net economic cost of compliance against the clear financial baseline established by contract termination mechanisms.

Unbounded contractual commitments destroy enterprise value far faster than agreed cash regulatory break fees.

Draft

Translating commercial risk allocation into enforceable contractual provisions demands precise language tailored to governing law. Corporate counsel drafting cross-border purchase agreements must harmonize regulatory effort covenants, material adverse effect definitions, divestiture carveouts, and dispute resolution clauses across conflicting legal jurisdictions. A failure in contractual syntax can invalidate carefully negotiated economic allocations when reviewed by judicial arbitrators or state chancery courts.

Delaware courts, English commercial courts, and Singapore international arbitration tribunals interpret regulatory effort covenants through distinct analytical frameworks. Delaware chancery judges hold parties strictly to explicit contractual language, enforcing negotiated divestiture exclusions and capping obligations precisely as written. English courts apply rigorous textual interpretation standards, refusing to imply broad hell or high water duties into general best efforts clauses unless explicit structural commitments appear within the contract text.

Specific Carveout Mechanics in Complex Treaties

Transaction counsel carve out specific assets or technologies from general clearance covenants to preserve core strategic value. A precise carveout clause specifies exact corporate entities, operational divisions, patent families, and geographic facilities that the buyer is strictly excused from divesting or modifying. The drafting must eliminate ambiguity regarding whether an asset falls within mandatory regulatory remedy schedules.

When drafting asset exclusions, counsel must explicitly address indirect structural concessions, such as mandatory intellectual property licensing, supply agreement modifications, and governance isolation orders. A clause that shields physical assets from sale but fails to exclude mandatory, non-exclusive IP licensing grants regulators a backdoor mechanism to strip target value while remaining technically compliant with the contract text.

Clause 8.02(c) of a cross-border acquisition contract demonstrates robust carveout architecture: “Notwithstanding anything to the contrary in Section 8.02(a) or Section 8.02(b), the Buyer shall not be required to (i) sell, hold separate, license, or dispose of any asset, product line, or technology of the Buyer or its Affiliates set forth on Schedule 8.02(c) (the ‘Protected Assets’), (ii) accept any restriction on the operational management or supply chain integration of the Protected Assets, or (iii) enter into any National Security Agreement or Proxy Agreement that restricts the Buyer’s access to, or voting control over, the entities holding the Protected Assets.”

Drafting hell or high water covenants without explicit financial caps on divestment transforms regulatory approval risk into an unbounded equity liability.

Selecting Chancery jurisdiction in Delaware or Commercial Court jurisdiction in London shapes how courts resolve disputes over regulatory effort compliance. Delaware courts routinely evaluate whether a buyer acted in good faith when prosecuting regulatory filings, inspecting board minutes, regulatory correspondence, and internal emails to verify if the buyer mounted a genuine effort to secure clearance before claiming statutory impossibility.

Governing Law and Forum Selection for Remedy Disputes

The enforcement of regulatory commitment covenants depends heavily on the judicial forum selected to resolve transaction disputes. International arbitration frameworks under ICC, LCIA, or SIAC rules offer confidentiality and global enforceability under the New York Convention, which appeals to foreign investors seeking to shield sensitive national security submissions from public court dockets. However, arbitral tribunals lack statutory authority to issue immediate injunctive relief forcing a foreign party to make regulatory filings or accept regulatory remedies before statutory drop-dead dates expire.

State court litigation provides powerful interim remedies, including specific performance orders requiring parties to submit filings, attend agency hearings, and execute mitigation agreements. Delaware Chancery Court routinely issues expedited specific performance decrees forcing reluctant buyers to fulfill regulatory commitments, provided the purchase agreement explicitly stipulates that money damages represent inadequate compensation for breach of regulatory covenants.

Drafting effective foreign investment approval provisions requires complete alignment across four distinct document sections: the regulatory efforts covenant, the material adverse effect definition, the drop-dead extension rules, and the reverse termination fee schedule. A single textual inconsistency across these provisions creates legal ambiguity, enabling a party to exploit conflicting language to walk away from a deal under regulatory pressure.

Foreign investment screening statutes continue to expand across industrial nations, broadening national security definitions to encompass artificial intelligence data pipelines, sovereign supply chain nodes, and critical infrastructure real estate. Deal principals drafting transaction documents must treat regulatory risk allocation as a foundational equity decision rather than a boilerplate legal closing condition.

If a national security agency mandates a divestiture that destroys the acquirer’s strategic rationale but falls below the contractually defined material adverse effect financial threshold, can the buyer successfully assert frustration of purpose under governing corporate law to avoid equity liability?
