Gun-Jumping & Pre-Closing Conduct Guide

Gun-jumping is a term of art in competition law that encompasses two distinct but related violations in the context of mergers, acquisitions, and combinations: (1) failure to notify a reportable transaction to the relevant competition authority before closing; and (2) premature implementation — taking steps to exercise control over, integrate with, or coordinate competitive behaviour with the target enterprise before the competition authority has granted clearance. Both forms of gun-jumping attract substantial penalties across all major merger control jurisdictions.

The rationale for gun-jumping prohibitions is straightforward. Merger control regimes exist to assess whether a proposed combination will cause an appreciable adverse effect on competition before the transaction is consummated. If parties are permitted to integrate their businesses or coordinate their competitive behaviour during the review period, the very purpose of ex ante merger control is defeated. Even if the transaction is ultimately cleared, the competitive harm from premature integration — customer losses, employee departures, data commingling, system integration — may be irreversible.

The gun-jumping risk is not limited to the period between signing and closing. It extends to any conduct that amounts to the exercise of decisive influence or control over the target, including involvement in day-to-day commercial decisions, exchange of competitively sensitive information beyond what is necessary for legitimate due diligence purposes, and implementation of integration plans before clearance is obtained. In several landmark cases, authorities have found gun-jumping violations even where the parties had filed the notification but had not yet received clearance.

For M&A practitioners, the challenge lies in navigating the boundary between legitimate pre-closing activities — due diligence, integration planning, interim operating covenants, customer and employee communications — and impermissible premature implementation. This boundary is fact-specific and varies across jurisdictions, but the consequences of crossing it are severe: fines running into hundreds of millions of euros, reputational damage, and in extreme cases, unwinding of the completed transaction.

This guide provides a comprehensive analysis of gun-jumping rules and pre-closing conduct obligations across three major jurisdictions — India, the European Union, and the United States — with references to UK enforcement where relevant. It draws on real enforcement actions and decisions to illustrate the practical boundaries of permissible conduct, and provides actionable compliance frameworks for deal teams, integration planners, and in-house counsel.

India's gun-jumping prohibition is rooted in Section 6(2) of the Competition Act, 2002, which provides that no combination shall come into effect until the Competition Commission of India (CCI) has approved it or until 210 days have elapsed from the date of notification (the deemed approval period). Section 6(2A), introduced by the Competition (Amendment) Act, 2023, further strengthens this by making it explicit that parties must not consummate or implement a combination, in whole or in part, before receiving CCI approval.

The penalty for gun-jumping under Section 43A is severe: the CCI may impose a penalty of up to 1% of the total turnover or total assets, whichever is higher, of the combination. For large transactions involving enterprises with turnover in the thousands of crores, this can translate to penalties of several hundred crore rupees. Additionally, the CCI retains the power under Section 31 to direct the parties to reverse the combination if it finds that the transaction causes or is likely to cause an appreciable adverse effect on competition (AAEC) in India.

The Competition (Amendment) Act, 2023 introduced several changes relevant to gun-jumping. The new deal value threshold under Section 5 (transactions exceeding INR 2,000 crore where the target has substantial business operations in India) expands the universe of notifiable transactions, meaning more transactions are subject to the standstill obligation. The amendment also reduced the deemed approval period from 210 days to a more streamlined review framework, with the CCI aiming to process Form I notifications within 30 working days and Green Channel filings within 15 working days.

The CCI has issued guidance and orders clarifying what constitutes impermissible pre-closing conduct in the Indian context. Key principles include:

• No exercise of voting rights or board control: The acquirer must not exercise voting rights attached to the acquired shares or appoint nominees to the target's board before CCI approval, except where such rights existed prior to the transaction.
• No involvement in commercial decisions: The acquirer must not influence the target's pricing, customer engagement, marketing strategy, capital expenditure decisions, or employee hiring and termination decisions during the pendency of the CCI review.
• Information exchange must be limited: Exchange of competitively sensitive information (pricing data, customer lists, cost structures, strategic plans) must be confined to what is strictly necessary for due diligence or for determining the transaction value, and must be subject to appropriate clean team or confidentiality arrangements.
• No integration of operations: Physical integration of offices, IT systems, sales forces, distribution networks, or supply chains before CCI clearance is impermissible.

The CCI's enforcement posture on gun-jumping has been progressively strengthening. The 2023 amendments signal a legislative intent to bring India's gun-jumping regime in line with the more stringent EU and US frameworks. Practitioners advising on Indian transactions must now treat the standstill obligation with the same seriousness as the EU's Article 7 EUMR prohibition — a significant shift from the earlier perception that India's gun-jumping enforcement was relatively lenient.

European Union — Article 7 EUMR: The standstill obligation under the EU Merger Regulation is contained in Article 7(1) of Council Regulation (EC) No 139/2004, which provides that a concentration with a Community dimension shall not be implemented before it has been notified and declared compatible with the common market. The prohibition is absolute: any implementation — partial or total — before clearance constitutes a violation, regardless of the parties' intent or the ultimate competitive effects of the transaction.

The European Commission has interpreted "implementation" broadly. In Ernst & Young/KPMG Denmark (Case C-633/16, CJEU 2018), the Court of Justice drew a distinction between measures that contribute to a change in control (which are caught by Article 7) and measures that are merely preparatory or ancillary (which are not). The Court held that the termination of a cooperation agreement by one of the merging parties, even before notification, did not constitute implementation because it did not in itself confer control over the target. However, this narrow exception has not prevented the Commission from pursuing aggressive enforcement in other cases.

Penalties for breaching Article 7 can reach up to 10% of the aggregate worldwide turnover of the undertaking concerned. The Commission has imposed landmark fines in three major gun-jumping cases:

• Marine Harvest/Morpol (2014): Marine Harvest acquired a 48.5% stake in Morpol through a public offer, which — together with the remaining dispersed shareholding — conferred de facto sole control. Marine Harvest notified the concentration only after completing the share purchase. The Commission fined Marine Harvest EUR 20 million for implementing the concentration before notification and clearance.
• Altice/PT Portugal (2018): Altice was fined EUR 124.5 million for exercising decisive influence over PT Portugal during the period between signing and CCI clearance. The Commission found that Altice had vetoed PT Portugal's marketing campaigns, pricing decisions, and key customer contracts; had required PT Portugal to seek Altice's prior approval for entering into or renegotiating contracts above certain thresholds; and had received and acted upon commercially sensitive information about PT Portugal's ongoing business performance.
• Canon/Toshiba Medical Systems (2019): Canon was fined EUR 28 million for implementing a two-step transaction structure (an interim acquisition by a special purpose vehicle, followed by a second step transferring control to Canon) designed to avoid triggering the notification obligation. The Commission found that the two steps constituted a single concentration and that the first step amounted to partial implementation.

United States — HSR Act: Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, parties to a reportable transaction must file a notification and observe a mandatory waiting period of 30 calendar days (15 days for cash tender offers) before consummating the acquisition. The waiting period may be extended by the issuance of a Second Request for additional information, in which case the parties may not close until 30 days after substantial compliance with the Second Request.

Failure to file or observe the waiting period can result in civil penalties of up to USD 51,744 per day (2025 rate, adjusted annually for inflation). Beyond the technical filing violation, the DOJ and FTC also pursue gun-jumping claims where parties coordinate competitive behaviour during the waiting period. In Flakeboard/SierraPine (2014), the DOJ obtained a USD 3.8 million penalty for gun-jumping based on evidence that the parties had coordinated pricing and customer allocation during the pre-closing period. In Gemstar-TV Guide (2003), the parties paid USD 5.67 million to settle FTC charges that they had illegally exchanged competitively sensitive information and coordinated business strategies before the transaction closed.

The US approach to gun-jumping analysis focuses on whether the conduct amounts to an illegal transfer of beneficial ownership before the waiting period expires. The DOJ's 2018 guidance on pre-consummation coordination emphasises that the acquiring party must not obtain "beneficial ownership" of the target's business by controlling its competitive decision-making — even if legal title has not passed. This includes directing the target's pricing, output, or competitive strategy; integrating sales or marketing teams; or sharing competitively sensitive information outside of clean team arrangements.

Gun-jumping violations can be categorised into three broad types, each with distinct factual characteristics and enforcement implications. Understanding these categories is essential for structuring pre-closing conduct protocols and identifying risk areas in any transaction.

Type 1 — Failure to Notify (Procedural Gun-Jumping): This is the most straightforward form of gun-jumping: completing a notifiable transaction without filing the required notification. It may arise from a genuine failure to identify a filing obligation (e.g., because the parties did not conduct a thorough jurisdictional assessment), from a deliberate decision not to file, or from a structural arrangement designed to circumvent the notification requirement. The Canon/Toshiba Medical Systems case is an example of the latter — Canon structured the acquisition through an interim SPV to argue that the first step did not confer control and therefore did not require notification. The Commission disagreed and fined Canon EUR 28 million.

Type 2 — Premature Implementation (Substantive Gun-Jumping): This is the most commonly prosecuted form of gun-jumping and covers a wide range of conduct. The parties file the notification but take steps to implement the transaction — in whole or in part — before clearance is obtained. Premature implementation includes:

• Exercise of control: The acquirer exercises voting rights, appoints directors, or otherwise participates in the governance of the target. In Marine Harvest/Morpol, the acquisition of a 48.5% stake (conferring de facto sole control) before notification constituted implementation.
• Commercial coordination: The parties coordinate pricing, customer allocation, marketing strategy, or output levels. In Altice/PT Portugal, Altice's involvement in PT Portugal's pricing decisions and customer contract negotiations was the primary basis for the EUR 124.5 million fine.
• Operational integration: The parties begin integrating IT systems, combining sales forces, merging offices, or consolidating supply chains before clearance. Even preparatory steps — such as entering into binding integration contracts with third-party vendors — may constitute implementation.
• Financial integration: Combining treasury functions, cross-guaranteeing debt, or altering the target's capital structure at the acquirer's direction before clearance.

Type 3 — Illegal Information Exchange: Even without direct commercial coordination, the exchange of competitively sensitive information between the parties during the pre-closing period can constitute gun-jumping if it goes beyond what is necessary for legitimate due diligence purposes. This is particularly significant where the parties are horizontal competitors — i.e., they operate in the same relevant market. In such cases, the exchange of pricing data, customer lists, cost structures, capacity utilisation rates, or strategic business plans may amount to a concerted practice or information exchange in violation of competition law (Section 3 of the Competition Act in India, Article 101 TFEU in the EU, Section 1 of the Sherman Act in the US), independent of any gun-jumping violation.

The Gemstar-TV Guide enforcement action in the US illustrates this risk. The FTC found that the parties had shared competitively sensitive information about their respective businesses — including pricing strategies, customer negotiations, and product development plans — during the pre-closing period, in a manner that went well beyond what was necessary for due diligence or integration planning. The FTC characterised this as both a gun-jumping violation (premature coordination) and a standalone violation of Section 5 of the FTC Act.

It is critical to understand that these three types of violations are not mutually exclusive. A single course of pre-closing conduct may involve elements of all three — e.g., the parties fail to notify a transaction (Type 1), begin integrating operations during the pre-signing due diligence period (Type 2), and exchange competitively sensitive information outside of any clean team arrangement (Type 3). Competition authorities will typically pursue the most serious violation but may aggregate the penalties for multiple violations in the same transaction.

Due diligence is a necessary and legitimate part of any M&A transaction. The buyer must assess the target's business, financial condition, legal liabilities, and competitive position to determine the transaction value and negotiate appropriate warranties and indemnities. This inevitably requires the exchange of information between the parties. However, where the parties are competitors (or potential competitors), the information exchanged during due diligence may include data that, if shared outside the transaction context, would constitute an illegal exchange of competitively sensitive information.

The key principle governing information exchange during due diligence is proportionality: the information shared must be necessary for the legitimate purposes of evaluating and executing the transaction, and must be subject to appropriate safeguards to prevent its use for competitive purposes. Competition authorities across jurisdictions have converged on the following framework for assessing the permissibility of pre-closing information exchange:

Permissible information exchange:

• Aggregated or anonymised financial data (revenue, EBITDA, margins at a business unit level) necessary for valuation;
• Historical data (more than 12 months old) that has limited competitive significance;
• Information about the target's legal and regulatory compliance (contracts, litigation, licences);
• Employee data necessary for assessing workforce composition and benefit obligations (subject to data protection laws);
• Facility and asset information necessary for assessing physical condition and environmental liabilities;
• Information shared exclusively with external advisers (lawyers, accountants) who are not involved in competitive decision-making.

Restricted information (requires clean team arrangements):

• Customer-specific pricing and discount structures;
• Forward-looking business plans, including pricing strategy, product launch timelines, and capacity expansion plans;
• Individual customer contracts and terms (especially where the parties compete for the same customers);
• Supplier terms and cost structures at a granular level;
• Technology roadmaps and R&D pipeline details;
• Sales force compensation structures and incentive plans.

Prohibited information exchange (even with clean team):

• Real-time competitive intelligence (current bid prices, pending proposals to shared customers, ongoing tender information);
• Information shared for the purpose of coordinating competitive behaviour (joint pricing, market allocation, bid rigging) — this constitutes a standalone cartel violation regardless of any transaction;
• Information that flows from the acquirer to the target (reverse information flow) about the acquirer's competitive strategy, which the target could use to adjust its own competitive behaviour during the pre-closing period.

The practical challenge is that the line between these categories is not always clear. A customer list with pricing information may be necessary for valuation (permissible purpose) but simultaneously provides the acquirer with insight into the target's competitive positioning that it could use to adjust its own bidding strategy (impermissible use). The solution lies in the design and implementation of robust clean team protocols, which are discussed in the following section.

The CCI's decisional practice and the European Commission's guidance both emphasise that the purpose of the information exchange is not dispositive — the effect on competitive decision-making is what matters. Even information shared in good faith for due diligence purposes can give rise to a gun-jumping or competition law violation if it is received by individuals involved in day-to-day competitive decisions and if no safeguards are in place to prevent its competitive use.

A clean team (also called an "information barrier" or "ethical wall" arrangement) is the primary mechanism for managing the exchange of competitively sensitive information during the pre-closing period. The clean team comprises designated individuals — typically external advisers (lawyers, accountants, consultants) and a limited number of internal personnel who are not involved in day-to-day competitive decision-making — who are authorised to receive and review restricted information from the other party.

The clean team protocol should be established before the data room opens and should be documented in a formal written agreement between the parties. The protocol typically includes the following elements:

Clean team composition:

• External advisers: External legal counsel, financial advisers, accountants, and consultants are the safest clean team members because they are not involved in the parties' competitive decision-making and are bound by professional confidentiality obligations.
• Internal clean team members: A limited number of internal personnel may be included where their expertise is essential for evaluating the target's business. These individuals must be identified by name, must sign individual confidentiality undertakings, and must be walled off from the company's competitive decision-making processes for the duration of the clean team arrangement.
• Exclusions: Personnel involved in pricing, sales, marketing, customer relationship management, or competitive strategy should generally be excluded from the clean team. Senior executives may participate in limited, high-level briefings but should not receive granular competitively sensitive data.

Information classification: The protocol should establish a clear classification system for the information exchanged during due diligence:

• Green category: Non-sensitive information that can be shared freely (corporate structure, audited financial statements, publicly available data).
• Amber category: Information that can be shared with the clean team but not with commercial decision-makers without aggregation or anonymisation (customer contracts, pricing schedules, cost data).
• Red category: Highly sensitive information that can only be reviewed by external advisers or under strict ring-fencing protocols (real-time pricing data, current tender submissions, competitive intelligence reports).

Access controls: The data room should implement access controls that restrict each category of information to the appropriate clean team members. Virtual data rooms (VDRs) provided by platforms such as Intralinks, Datasite, or Firmex support granular user-level access permissions, audit trails, and watermarking. Physical data rooms (if used) should have sign-in logs, supervised access, and prohibitions on copying or photographing documents.

Reporting and audit: The clean team protocol should include regular reporting by clean team members to the parties' external counsel on the information reviewed and any concerns identified. The protocol should also provide for periodic audits of compliance, including review of data room access logs and interviews with clean team members.

Duration and unwinding: The clean team arrangement continues until the transaction closes (at which point the information barriers are no longer necessary) or is abandoned (at which point all restricted information must be returned or destroyed, and clean team members must certify that they have not disclosed restricted information to non-clean team personnel). The protocol should specify the unwinding procedures in detail.

In practice, clean team protocols are most critical in horizontal mergers — transactions between competitors. In vertical or conglomerate transactions, the parties typically do not compete in the same markets, and the risk of information exchange leading to competitive coordination is lower (though not zero). However, even in non-horizontal transactions, clean team arrangements are advisable where the parties have supplier-customer relationships or where one party possesses information about shared customers or competitors that could be commercially valuable to the other.

Interim operating covenants (also called "pre-closing covenants" or "conduct of business covenants") are contractual provisions in the transaction agreement that govern how the target business is operated during the period between signing and closing. Their primary purpose is to preserve the value of the target business for the buyer — ensuring that the seller does not strip assets, take on excessive liabilities, or make material changes that would alter the business the buyer contracted to acquire.

However, interim operating covenants also raise gun-jumping concerns. If the covenants are drafted too broadly, they may effectively transfer operational control of the target to the buyer before clearance — which is precisely what the standstill obligation prohibits. The European Commission specifically identified this risk in Altice/PT Portugal, where Altice's contractual right to approve PT Portugal's material contracts, pricing decisions, and customer negotiations was held to constitute the exercise of decisive influence before clearance.

The standard formulation of an interim operating covenant requires the target to conduct its business in the ordinary course consistent with past practice and to refrain from taking specified material actions without the buyer's prior written consent. The tension lies in the scope of actions requiring consent:

Permissible consent rights (value preservation):

• Material acquisitions or disposals of assets above a specified threshold;
• Incurring debt or financial obligations above a specified threshold;
• Material changes to employee compensation or benefits (above a specified threshold or affecting senior management);
• Amendment or termination of material contracts (above a specified threshold);
• Changes to accounting policies or tax elections;
• Declaration of dividends or distributions;
• Capital expenditure above agreed budgets.

Potentially problematic consent rights (may constitute gun-jumping):

• Approval of individual customer contracts or pricing decisions (particularly where the buyer and target compete for the same customers);
• Approval of marketing campaigns or promotional pricing;
• Approval of routine hiring decisions or employee transfers;
• Approval of ordinary-course supplier negotiations;
• Any right that allows the buyer to direct the target's competitive behaviour in the market.

The key distinction is between consent rights designed to prevent value destruction (legitimate) and consent rights that effectively give the buyer a veto over the target's competitive decisions (impermissible). In Altice/PT Portugal, the Commission found that the consent thresholds were set so low that they captured ordinary-course business decisions, and that Altice actively exercised these rights to influence PT Portugal's day-to-day operations — requesting changes to pricing, vetoing promotional campaigns, and directing customer negotiations.

Best practice is to set consent thresholds at a level that captures genuinely material decisions but does not reach ordinary-course commercial activity. As a rule of thumb, thresholds should be set at or above the target's normal decision-making authority levels — i.e., if the target's management would ordinarily have authority to approve a contract up to a certain value without board approval, the buyer's consent right should not be triggered below that level. Where consent rights do extend to competitive decisions (e.g., because the target operates in a regulated industry where pricing changes have long-term consequences), the protocol should ensure that the buyer's role is limited to reviewing the decision for value-preservation purposes and does not extend to directing the outcome.

Integration planning is one of the most important determinants of post-closing success in any M&A transaction. Studies consistently show that transactions where integration planning begins early — during the due diligence phase — achieve better outcomes than those where planning is deferred until after closing. However, the line between legitimate pre-closing integration planning and impermissible premature implementation is one of the most difficult boundaries in gun-jumping compliance.

The core principle, recognised by all major competition authorities, is that planning for integration is permissible; implementing integration plans is not. This principle is easy to state but difficult to apply in practice, because integration planning necessarily involves making decisions, allocating resources, and entering into commitments that, if taken too far, cross into implementation.

Permissible integration planning activities:

• Developing organisational charts and management structures for the combined entity (provided these are not communicated to employees of the target or implemented before closing);
• Identifying synergy opportunities and developing synergy realisation plans;
• Designing IT system migration and integration architectures (provided no systems are actually connected or data migrated before closing);
• Developing customer and employee communication plans for the Day 1 announcement;
• Engaging external consultants to advise on integration workstreams;
• Developing a 100-day plan for post-closing integration milestones;
• Identifying regulatory approvals and permits that will need to be transferred post-closing.

Impermissible premature integration:

• Implementing organisational changes at the target (appointing new managers, restructuring teams, terminating employees) before closing;
• Connecting IT systems, migrating data, or granting the acquirer access to the target's operational systems;
• Combining sales forces, redirecting customer accounts, or jointly bidding on contracts;
• Entering into binding contracts with third-party integration service providers (e.g., IT vendors, relocation firms) that create obligations irrespective of whether the transaction closes;
• Directing the target's procurement or supply chain decisions to align with the acquirer's arrangements;
• Issuing joint marketing materials or presenting the combined entity to customers or industry bodies.

A particularly sensitive area is employee retention. In many transactions, the acquirer wishes to identify and retain key employees of the target. Pre-closing discussions with the target's employees about their future roles, compensation, or reporting lines in the combined entity can constitute premature implementation if they amount to the acquirer directing the target's human resources decisions. The safer approach is for the target's own management to handle employee communications during the pre-closing period, with the acquirer limited to providing high-level assurances about the combined entity's plans that do not commit specific individuals to specific roles.

The European Commission's Altice/PT Portugal decision is the most detailed articulation of the boundary between planning and implementation. The Commission found that Altice had crossed the line by, among other things: instructing PT Portugal to delay or renegotiate specific customer contracts; directing PT Portugal to appoint specific individuals to management positions; requesting and receiving detailed reports on PT Portugal's daily operations; and involving itself in PT Portugal's responses to competitors' actions. Each of these activities went beyond planning and constituted the exercise of decisive influence over PT Portugal's business before clearance was obtained.

Best practice is to establish a clear "integration planning protocol" that distinguishes between planning activities (which proceed) and implementation activities (which are held until Day 1). The protocol should designate a small integration planning team, establish reporting lines to external counsel for gun-jumping compliance review, and require that all integration activities are reviewed for compliance before being undertaken.

Gun-jumping enforcement has intensified dramatically over the past decade, with competition authorities across major jurisdictions imposing fines that rival penalties for substantive antitrust violations. The following table summarises the most significant gun-jumping enforcement actions globally:

Case	Jurisdiction	Year	Fine / Penalty	Violation Type
Altice/PT Portugal	EU	2018	EUR 124.5 million	Exercise of decisive influence before clearance
Illumina/GRAIL	EU	2023	EUR 432 million	Closing in breach of standstill obligation (Article 7) + separate Article 14 fine for negligent implementation
Canon/Toshiba Medical Systems	EU	2019	EUR 28 million	Warehousing structure to circumvent notification
Marine Harvest/Morpol	EU	2014	EUR 20 million	Acquisition of de facto control before notification
Facebook (Meta)/Giphy — IEO breach	UK	2022	GBP 50.5 million	Repeated breach of Initial Enforcement Order
Flakeboard/SierraPine	US	2014	USD 3.8 million	Coordination of pricing and customer allocation during waiting period
Gemstar-TV Guide	US	2003	USD 5.67 million	Illegal information exchange and coordination before closing
Electro Rent/Microlease	EU	2019	No fine (finding of violation)	Failure to notify; Commission cleared retroactively

Several trends emerge from this enforcement landscape. First, the quantum of fines is escalating. The Illumina/GRAIL fine of EUR 432 million — imposed for closing a transaction that the Commission had prohibited — represents the highest gun-jumping penalty in history and signals the Commission's determination to treat standstill violations as seriously as cartel behaviour. Second, procedural violations are not treated as minor infractions. The Altice fine of EUR 124.5 million was imposed even though the underlying transaction was ultimately cleared unconditionally — the gun-jumping violation existed independently of the transaction's competitive effects.

Third, structural circumvention is not tolerated. The Canon/Toshiba Medical Systems case demonstrates that competition authorities will look through artificial transaction structures designed to avoid the notification obligation. Canon's use of an interim SPV — which technically acquired the shares before Canon itself — was held to be a sham designed to avoid the standstill requirement. Fourth, UK IEO enforcement has emerged as a significant independent risk. The CMA's GBP 50.5 million fine against Facebook/Meta for repeated breaches of the IEO in the Giphy case is among the largest procedural fines imposed by any competition authority globally, and reflects the CMA's willingness to use its interim measures powers aggressively.

Beyond financial penalties, gun-jumping violations carry significant reputational consequences. A finding of gun-jumping can damage the parties' relationship with the competition authority, making future interactions more difficult. It can also trigger follow-on private litigation from competitors, customers, or shareholders who claim to have suffered loss as a result of the premature implementation. In extreme cases, the authority may order the unwinding of a completed transaction — as the CMA did in Facebook/Giphy, requiring Meta to divest Giphy entirely.

The CCI's gun-jumping enforcement record, while not yet at the scale of EU enforcement, has developed steadily since the merger control regime became operational in June 2011. Several notable orders illustrate the CCI's approach and the increasing seriousness with which it treats standstill violations.

SCM Solifert/Deepak Fertilisers (2014): This was one of the CCI's earliest gun-jumping enforcement actions. SCM Solifert Pte Ltd acquired a controlling stake in Deepak Fertilisers and Petrochemicals Corporation Limited without filing the required notification under Section 6. The CCI imposed a penalty of INR 1 crore under Section 43A for failure to notify. While modest by global standards, the order established the CCI's willingness to enforce the filing obligation and served as an early warning to the M&A community.

Thomas Cook (India)/Sterling Holiday Resorts (2014-2015): Thomas Cook (India) Limited acquired Sterling Holiday Resorts (India) Limited through a scheme of arrangement. The CCI examined whether the parties had begun implementing the combination before receiving CCI approval. The CCI's analysis focused on whether any transfer of shares, assets, or control had occurred during the review period. While the CCI ultimately cleared the transaction, the inquiry itself highlighted the CCI's attention to pre-closing conduct in scheme of arrangement transactions — which have unique timing issues because the NCLT/NCLAT approval process may create pressure to complete procedural steps before CCI clearance.

UltraTech/Binani Cement (2018): This case involved UltraTech Cement's acquisition of Binani Cement through the insolvency resolution process under the Insolvency and Bankruptcy Code, 2016. The transaction raised gun-jumping questions because the resolution process created time pressures that were in tension with the CCI's review timeline. The CCI addressed the interface between the IBC process and merger control requirements, emphasising that the CCI filing obligation applies to acquisitions through the insolvency resolution process and that parties cannot close such transactions without CCI clearance, notwithstanding the IBC's time limits. The CCI cleared the combination but the case underscored the importance of factoring CCI review timelines into resolution plans.

Mylan/Biocon Biologics (2022): Mylan's (now Viatris's) investment in Biocon Biologics raised gun-jumping considerations related to the phased nature of the transaction and the governance arrangements during the interim period. The CCI examined whether the interim governance rights conferred on Mylan — including board representation and consent rights over material decisions — constituted the exercise of control before the final completion of the combination. The CCI's analysis mirrored the EU's approach in Altice/PT Portugal, focusing on whether the interim arrangements went beyond value preservation to constitute the exercise of decisive influence.

Recent developments (2024-2025): Following the 2023 amendments, the CCI has signalled a more proactive approach to gun-jumping enforcement. The CCI's Combination Division has published updated guidance emphasising that: (a) the standstill obligation applies from the date the parties are aware that the transaction is notifiable, not merely from the date of filing; (b) partial implementation (including the exercise of contractual consent rights that amount to control) is prohibited; and (c) the deal value threshold has expanded the scope of notifiable transactions and therefore the scope of the standstill obligation. Practitioners should expect CCI gun-jumping enforcement to increase in frequency and severity in the coming years, particularly for transactions involving digital platforms and cross-border acquisitions.

The CCI has also clarified the interaction between gun-jumping and the Green Channel route. A transaction that qualifies for the Green Channel is deemed approved upon filing, which effectively eliminates the standstill period. However, if the CCI subsequently revokes the Green Channel approval (because the parties' self-assessment was incorrect), any integration steps taken during the interim period may retroactively constitute gun-jumping. This risk underscores the importance of a conservative Green Channel eligibility assessment.

An effective gun-jumping compliance framework should be established at the term sheet or letter of intent stage — before the transaction agreement is signed and well before competitively sensitive information begins to flow between the parties. The framework operates at three levels: contractual, organisational, and operational.

Level 1 — Contractual Safeguards:

• Transaction agreement provisions: The transaction agreement should include a clear acknowledgement that both parties will comply with all applicable merger control filing and standstill obligations. Interim operating covenants should be drafted with gun-jumping risks in mind — consent thresholds should be set at levels that capture material decisions but do not reach ordinary-course commercial activity. The agreement should include an explicit carve-out providing that nothing in the covenants requires either party to take, or refrain from taking, any action that would violate applicable competition law.
• Clean team agreement: A separate clean team agreement (or a schedule to the transaction agreement) should establish the clean team composition, information classification system, access controls, and reporting procedures. The agreement should be signed by all clean team members individually.
• Confidentiality agreement: The NDA governing due diligence should include specific provisions addressing the treatment of competitively sensitive information, restricting its use to transaction evaluation purposes, and requiring its return or destruction if the transaction does not proceed.

Level 2 — Organisational Measures:

• Gun-jumping compliance officer: Designate a senior individual (typically external competition counsel or a senior in-house lawyer) as the gun-jumping compliance officer responsible for reviewing all pre-closing interactions between the parties, approving information requests, and escalating potential issues.
• Integration planning team: Establish a dedicated integration planning team with clear terms of reference. The team should be authorised to develop integration plans but prohibited from taking any implementation steps before closing. All integration planning activities should be reviewed by the compliance officer.
• Training: Conduct gun-jumping compliance training for all deal team members, including members of the integration planning team, corporate development personnel, and any business unit leaders who will interact with the target's management. The training should cover: the legal framework and penalties; the distinction between planning and implementation; the clean team protocol; and practical dos and don'ts.

Level 3 — Operational Controls:

• Communication protocols: All communications between the parties should be channelled through designated contacts (typically the deal team leads or external counsel). Ad hoc communications between commercial personnel should be prohibited.
• Meeting protocols: Meetings between the parties' personnel should have a clear agenda reviewed in advance by the compliance officer. Minutes should be taken and reviewed. Competition counsel should attend meetings where competitively sensitive topics may arise.
• Document controls: All documents exchanged between the parties should be routed through the data room or a controlled exchange mechanism. Documents should be classified according to the clean team protocol and access should be restricted accordingly.
• Incident reporting: Establish a mechanism for reporting potential gun-jumping incidents (inadvertent information disclosure, unauthorised communications, etc.). Prompt reporting allows the compliance officer to assess the severity of the incident and take corrective action before a pattern develops.

The compliance framework should be proportionate to the transaction's risk profile. A horizontal merger between direct competitors requires the most robust safeguards — full clean team, strict information barriers, independent compliance officer, and comprehensive training. A vertical or conglomerate transaction with no competitive overlaps may require lighter-touch measures, though minimum safeguards (NDA provisions, communication protocols, and basic training) should always be implemented. The risk assessment should consider: the degree of horizontal overlap; the sensitivity of the information being exchanged; the duration of the pre-closing period; and the enforcement posture of the relevant competition authorities.

Finally, the compliance framework should be documented. Competition authorities take into account the existence and adequacy of compliance measures when assessing the gravity of a gun-jumping violation. A well-documented compliance programme — even if it did not prevent every violation — may serve as a mitigating factor in penalty determination.

Cross-border transactions present unique gun-jumping challenges because the standstill obligations of multiple jurisdictions may apply simultaneously, each with its own scope, duration, and enforcement consequences. The parties must comply with the most restrictive standstill requirement across all relevant jurisdictions — which in practice means that no closing or implementation step can be taken until clearance (or expiry of the review period) has been obtained in all applicable jurisdictions.

Stacking of standstill obligations: In a multi-jurisdictional transaction, the effective standstill period is the longest across all filing jurisdictions. For example, if the transaction requires filings in India (30 working day review, 210-day outer limit), the EU (25 working days Phase I, up to 125 working days Phase II), and the US (30 calendar days, potentially extended by a Second Request), the parties cannot close until all three jurisdictions have granted clearance. This can result in a pre-closing period of 6-18 months for complex global transactions — during which the parties must maintain strict gun-jumping compliance.

Divergent standards: The substantive standard for what constitutes impermissible pre-closing conduct varies across jurisdictions. The EU's Article 7 EUMR is widely regarded as the most expansive, with the Altice decision establishing a broad interpretation of "implementation" that captures any exercise of decisive influence over the target's commercial decisions. The US standard focuses on the transfer of "beneficial ownership" and is somewhat narrower — but the DOJ and FTC have pursued aggressive enforcement of information exchange and competitive coordination violations. India's standard, following the 2023 amendments, is converging with the EU's approach. The UK's IEO regime operates differently from the standstill obligations of mandatory-notification jurisdictions, but the consequences of non-compliance are equally severe.

Practical implications for multi-jurisdictional compliance:

• Apply the most restrictive standard globally: Rather than attempting to apply different standards in different jurisdictions, the safest approach is to design the gun-jumping compliance framework around the most restrictive applicable standard — which in most cases will be the EU's Altice-informed approach.
• Coordinate filing timelines: Sequence filings to minimise the total pre-closing period. File first in jurisdictions with the longest review timelines. Engage in pre-notification consultation in parallel across jurisdictions.
• Address conditionality carefully: The transaction agreement should condition closing on obtaining all required merger control clearances. Where clearance conditions differ across jurisdictions (e.g., structural remedies in the EU, behavioural commitments in India), the agreement should address how conflicting conditions are resolved.
• Joint defence and privilege: Pre-closing communications between the parties' competition counsel regarding merger control filings and gun-jumping compliance should be subject to legal privilege protections. However, the scope of privilege varies across jurisdictions (in-house counsel communications are not privileged in the EU under the Akzo Nobel doctrine), and parties should structure their communications accordingly.
• Agency cooperation: Competition authorities increasingly cooperate with each other on merger investigations, including through bilateral cooperation agreements and the ICN. Information shared with one authority may be shared with others (subject to confidentiality waivers). This means that gun-jumping conduct discovered in one jurisdiction may trigger enforcement in another — the parties cannot compartmentalise their compliance.

Jurisdictions requiring particular attention: Beyond the four major regimes (India, EU, US, UK), several other jurisdictions have active gun-jumping enforcement:

• Brazil (CADE): Brazil's mandatory pre-merger notification regime with a 240-day review period creates a long standstill period. CADE has imposed fines for failure to notify and has investigated pre-closing conduct.
• China (SAMR): China's review timeline can extend to 180+ calendar days. SAMR has imposed fines for failure to notify (typically CNY 500,000, but higher penalties are available under the 2022 amendment to the Anti-Monopoly Law).
• South Korea (KFTC): The KFTC has imposed fines for failure to notify and for pre-closing implementation. Korea's regime allows post-closing notification for some transactions, but pre-closing implementation restrictions apply from the date the transaction is signed.
• Germany (Bundeskartellamt): Germany's deal value threshold (EUR 400 million) creates an additional filing trigger. The Bundeskartellamt has investigated gun-jumping allegations and has fined parties for failure to notify.

For any cross-border transaction, the gun-jumping compliance framework should be designed at the global level, with local adaptations as necessary for jurisdiction-specific requirements. A single global compliance protocol, applied consistently across all jurisdictions, reduces the risk of inconsistent treatment and provides a defensible position in the event of an enforcement inquiry.

The following checklists summarise the key safe harbour practices for pre-closing conduct and the steps to verify gun-jumping compliance before and at closing. These checklists should be adapted to the specific circumstances of each transaction.

Pre-Signing Checklist:

• Conduct jurisdictional mapping to identify all applicable filing obligations and standstill requirements.
• Assess gun-jumping risk profile (horizontal overlap, sensitivity of information, anticipated pre-closing period).
• Draft clean team protocol and information classification framework.
• Review and adjust interim operating covenants for gun-jumping compliance — ensure consent thresholds do not capture ordinary-course commercial decisions.
• Include merger control conditionality and standstill compliance provisions in the transaction agreement.
• Designate gun-jumping compliance officer.

Signing-to-Filing Checklist:

• Circulate clean team protocol to all deal team members and obtain signed acknowledgements.
• Conduct gun-jumping training for deal team, integration team, and relevant business unit personnel.
• Establish communication protocols and meeting procedures.
• Configure data room access controls according to the information classification framework.
• File merger control notifications in all applicable jurisdictions.
• Engage in pre-notification consultations where applicable (EU, India, UK).

Filing-to-Clearance Checklist (Active Standstill Period):

• Maintain strict separation of competitive decision-making — no involvement of acquirer personnel in target's pricing, marketing, or customer negotiations.
• Channel all inter-party communications through designated contacts.
• Ensure clean team members report regularly to compliance officer.
• Review data room access logs periodically for unauthorised access.
• Limit integration planning activities to planning only — no implementation steps.
• Monitor interim operating covenant interactions — ensure buyer does not exercise consent rights in a manner that directs target's competitive conduct.
• Respond to competition authority information requests promptly and consistently across jurisdictions.
• Document all compliance activities for the record.

Pre-Closing Verification Checklist:

• Confirm that clearance has been obtained (or the review period has expired) in all applicable jurisdictions.
• Verify compliance with any conditions attached to the clearance (divestitures, behavioural commitments).
• Obtain written confirmation from the compliance officer that no gun-jumping violations have been identified during the pre-closing period.
• Review any pending issues from incident reports and confirm that corrective actions have been taken.
• Confirm that all clean team obligations remain in effect until closing.

Safe Harbour Practices — Summary of Dos and Don'ts:

Permissible (Safe Harbour)	Impermissible (Gun-Jumping Risk)
Conducting due diligence through clean team arrangements	Sharing real-time competitive intelligence outside clean team
Developing post-closing integration plans (without implementing)	Implementing integration plans (combining systems, teams, or operations)
Communicating with customers/employees about the transaction in general terms	Jointly communicating with customers or presenting a combined offering
Setting high-level interim operating covenants for value preservation	Using consent rights to direct the target's day-to-day competitive decisions
Reviewing aggregated/historical financial data for valuation	Reviewing customer-specific pricing, live tenders, or forward-looking plans (without clean team)
Engaging external consultants for integration workstreams	Directing the target's employees to implement integration steps
Planning Day 1 organisational announcements	Appointing the acquirer's nominees to the target's board before closing
Monitoring the target's financial performance through agreed reporting	Participating in the target's commercial negotiations or competitive responses

These safe harbour practices are not absolute — their application depends on the specific facts and the governing jurisdiction. The overarching principle is that the parties must remain independent competitors throughout the pre-closing period. Any action that blurs this independence, whether through the exercise of control, the exchange of competitively sensitive information, or the implementation of integration steps, creates gun-jumping risk. When in doubt, the safe course is to defer the activity until after closing and clearance have been confirmed in all applicable jurisdictions.

Finally, maintain a compliance file throughout the pre-closing period. This file should include: the clean team protocol and signed acknowledgements; training materials and attendance records; communication logs; data room access reports; meeting minutes; incident reports and corrective actions; and the compliance officer's closing certificate. This file serves as contemporaneous evidence of the parties' good faith compliance efforts and is invaluable in the event of a subsequent enforcement inquiry.
