How Kenya's 2026 Merger‑control Reforms Affect M&A Deals, What Buyers, Sellers and Advisers Must Do in 2026

The Kenya merger control changes 2026 represent the most significant overhaul of the country’s competition-law framework in over a decade, shifting the regime from a voluntary, post-completion notification model to a fully suspensory, mandatory pre-merger clearance system administered by the Competition Authority of Kenya (CAK). These reforms introduce recalibrated merger notification thresholds, a new fee structure with materially higher costs for large transactions, and stricter enforcement powers that give the CAK the ability to unwind completed deals and impose substantial administrative penalties. Simultaneously, the broader East African regulatory environment is evolving, with COMESA’s Competition Commission updating its own merger practice notes and the EAC cross-border M&A policy framework creating additional layers of compliance for multi-jurisdiction transactions.

Compounding the urgency, the Constitutional Court’s landmark ruling on the General Anti-Avoidance Rule (GAAR) delivered on April 24, 2026, has introduced new uncertainty around tax-driven deal structuring, making robust due diligence indispensable for every transaction touching Kenyan assets or revenues.

Executive Summary: Immediate Compliance Actions for Deal Teams

For in-house counsel, private equity sponsors, and M&A advisers, the practical consequences of these reforms are immediate. Any transaction that meets the revised thresholds must now be notified to the CAK before closing, and parties are prohibited from implementing any aspect of the merger until formal clearance is received. Failure to comply exposes deal parties to fines, mandatory divestiture orders, and potential criminal liability.

The reformed regime demands a fundamental shift in how Kenya-facing deals are planned, documented, and executed. Deal timetables must now accommodate CAK review periods that can extend well beyond the statutory minimum, and transaction agreements must include robust conditionality clauses to address the risk of delayed or conditional clearance.

Deal teams should take these five compliance actions immediately:

• Notify early. Begin preparing the CAK filing pack as soon as the transaction structure is settled, do not wait for signing.
• Check thresholds carefully. Apply the revised merger notification thresholds to every acquisition of control, asset purchase, or joint venture involving Kenyan turnover or assets.
• Run tax due diligence on GAAR exposure. In light of the April 24, 2026 Constitutional Court judgment, scrutinise every tax-driven structuring element for recharacterisation risk.
• Budget for higher fees. The new merger filing fees Kenya 2026 schedule is materially more expensive, particularly for large cross-border transactions.
• Coordinate EAC and COMESA filings. Where transactions have a regional footprint, map all parallel filing obligations early and designate a lead jurisdiction strategy.

What Changed in 2026: The Headline Kenya Merger Control Changes 2026 You Must Know

The 2026 reforms touch three pillars of Kenya’s merger-control architecture: the notification regime itself, the thresholds that trigger a filing obligation, and the fees payable to the CAK. Each change has direct consequences for deal timing, cost, and risk allocation.

Suspensory Pre-Merger Regime: What “Suspensory” Means in Practice

The centrepiece of the Kenya merger control changes 2026 is the introduction of a suspensory merger control regime. Under the previous framework, parties could complete a transaction and notify the CAK after the fact, a system that gave the regulator limited leverage to intervene before market structures had already shifted. The reformed regime reverses this entirely.

Parties to a notifiable merger are now legally required to file with the CAK before completing or implementing any part of the transaction. This includes completing share transfers, exercising voting rights acquired through the transaction, integrating operations, or appointing new directors on behalf of the acquirer. The prohibition on implementation applies from the point at which the filing obligation arises, typically at signing or when binding commitments are exchanged, and remains in force until the CAK issues a written determination.

The enforcement consequences for breach are severe. The CAK has the power to declare a completed merger void, order divestiture of acquired assets or shares, and impose administrative penalties calculated as a percentage of the merged entity’s annual turnover. Industry observers expect the CAK to pursue early enforcement actions aggressively to establish the credibility of the new regime.

New Notification Thresholds and Definitions

The CAK’s revised Merger Threshold Guidelines recalibrate the financial tests that determine whether a transaction is notifiable. The new thresholds are structured around combined turnover and combined asset values of the merging parties within Kenya, with separate tests for the target entity to ensure that acquisitions of smaller businesses with meaningful local operations are also captured. Market share thresholds serve as an additional trigger in concentrated sectors.

The practical effect is a wider net. Transactions that would have fallen below the old thresholds, particularly mid-market private equity deals and bolt-on acquisitions, may now require notification. Deal teams should apply the threshold test at the earliest stage of transaction planning and re-verify if deal values shift during negotiations.

Increased Filing Fees and Fee Mechanics

The merger filing fees Kenya 2026 schedule introduces a tiered structure linked to the combined turnover or combined asset value of the merging parties. Smaller transactions attract a flat fee, while mid-market and large deals pay a percentage of combined turnover, subject to minimum and maximum caps. The headline rates represent a significant increase over the previous fee schedule, reflecting the CAK’s expanded mandate and the additional resources required to operate a suspensory system with statutory decision deadlines. Parties should factor these costs into their transaction budgets from the outset and confirm the precise fee calculation with the CAK before filing.

Who Must Notify? Practical Tests and Examples

Understanding who bears the notification obligation, and for which types of transaction, is critical under the reformed regime. The Competition Act’s definition of a “merger” is broad and captures a range of corporate transactions beyond traditional share acquisitions.

Control, Acquisition of Assets, Mergers vs. Share Deals

A notifiable merger arises whenever one or more undertakings directly or indirectly acquire or establish direct or indirect control over the whole or part of the business of another undertaking. “Control” is defined functionally: it includes the ability to materially influence the policy of an undertaking, whether through equity ownership, voting rights, contractual arrangements, or the ability to appoint or remove a majority of directors. This means that minority acquisitions conferring material influence, management agreements, and certain long-term supply or franchise arrangements may trigger a filing obligation.

Asset purchases are explicitly within scope. Where a buyer acquires a division, business unit, or specific assets (such as a brand, customer base, or manufacturing facility) that constitute a business, the transaction is treated as a merger for notification purposes. Share deals, whether full acquisitions or partial stake increases that cross a control threshold, are notifiable on the same basis.

Examples by Transaction Type

• Horizontal acquisition. A Kenyan FMCG company acquiring a direct competitor. Both parties’ Kenyan turnover and assets count toward the threshold test. Likely notifiable if combined figures exceed the revised minimums.
• Vertical integration. A manufacturer acquiring its primary distributor. Even where the target’s turnover is modest, the combined threshold test may be met. Consider whether the target’s assets, warehousing, logistics fleet, customer contracts, push the combined value above the line.
• Conglomerate / PE acquisition. A foreign private equity fund acquiring a Kenyan fintech platform. The fund’s global turnover is irrelevant; the test focuses on Kenyan turnover and assets. However, if the fund holds other Kenyan portfolio companies, their turnover may be aggregated.
• Asset purchase. Acquisition of a hotel chain’s Kenyan properties. The asset value of the properties, combined with the buyer’s existing Kenyan operations, determines notifiability.

Exemptions and Potential Carve-Outs

The reformed regime provides limited exemptions. Intra-group restructurings, where the ultimate beneficial ownership does not change, are generally exempt, provided the restructuring does not alter the competitive dynamics of the relevant market. Acquisitions by licensed financial institutions in the ordinary course of their business (such as taking security over shares) may also fall outside the notification obligation, though the CAK retains the discretion to require notification where the acquisition could lead to a lasting change of control.

For transactions that were pending or had been signed but not yet completed before the effective date of the suspensory regime, transitional provisions apply. The likely practical effect is that transactions signed before the commencement date but not yet closed must comply with the new rules, making it essential for deal teams with transactions in the pipeline to assess their filing obligations immediately.

Timeline, Process and Tactical Checklist for Deal Teams

The suspensory regime’s most immediate practical impact is on deal timetables. Every transaction that crosses the revised merger notification thresholds must now build in sufficient time for CAK review before completion can occur. This section provides the step-by-step process that buyers, sellers, and their advisers should follow.

CAK Filing Timeline and Statutory Decision Periods

Once a complete notification is filed, the CAK operates within defined statutory review periods. The initial (Phase I) review period runs for a set number of working days from the date of acceptance of a complete filing. If the CAK determines that a transaction raises no competition concerns, clearance is issued at the end of Phase I, or earlier if the regulator is satisfied before the deadline.

Where the CAK identifies potential concerns, for example, in concentrated markets or where the merged entity would hold a significant market share, the matter proceeds to an extended (Phase II) review. Phase II adds a further period of working days, during which the CAK may request additional information, commission market studies, and engage with third parties. The statutory clock stops while the parties respond to information requests, so incomplete or delayed responses can extend the total review period significantly.

For deal teams, the key planning parameter is the total elapsed time from filing to clearance. Industry observers expect that straightforward, unconcentrated transactions will clear within Phase I, while complex or cross-border deals should budget for Phase II timelines as a realistic base case.

Practical Filing Checklist

A complete CAK filing pack should include the following documents and information:

• Completed CAK merger notification form. This is the prescribed form available from the CAK’s mergers and acquisitions portal. All fields must be completed; incomplete forms will be returned and the statutory clock will not start.
• Transaction documents. Signed copies of the share purchase agreement, asset purchase agreement, subscription agreement, or other binding documents, including all schedules, annexures, and side letters.
• Corporate structure charts. Pre- and post-transaction group structure charts for both the acquirer and the target, showing all entities in the corporate group with Kenyan operations or turnover.
• Financial statements. Audited financial statements for the most recent three financial years for both parties (or the relevant Kenyan subsidiaries where the parties are foreign groups).
• Market data and competitive assessment. A description of the relevant product and geographic markets, including estimated market shares for the merging parties and their principal competitors, supply-chain relationships, and barriers to entry.
• Employee information. Total headcount, location of employees, and a statement on anticipated workforce changes post-transaction.
• Public interest considerations. Information on the transaction’s likely effects on employment, the ability of small and medium enterprises to compete, and the spread of ownership among historically disadvantaged persons, factors the CAK is required to consider under the Competition Act.
• Confidentiality requests. A separate schedule identifying any information for which confidential treatment is requested, with reasons, as the CAK’s file is accessible to third parties in certain circumstances.
• Filing fee payment confirmation. Proof of payment of the applicable merger filing fee.

Drafting Tips for SPA Clauses to Manage CAK Risk

The suspensory regime demands careful drafting of transaction agreements. Key clauses to address include:

• Condition precedent. Completion should be expressly conditional on obtaining unconditional CAK clearance (and, where applicable, COMESA clearance). The condition should be drafted broadly enough to cover any approval, consent, or non-objection from the CAK.
• Longstop date. Set the longstop date to accommodate the maximum realistic CAK review period, including a Phase II extension and potential information-request delays. A longstop date that is too tight creates termination risk if the CAK review is prolonged.
• Break fee / reverse break fee. Consider whether a break fee is appropriate if clearance is refused or subject to unacceptable conditions. Allocate the economic risk of regulatory delay between the parties.
• Interim operating covenants. Between signing and completion, the target must continue to operate in the ordinary course. Draft covenants that prevent gun-jumping, i.e., the acquirer exercising influence over the target’s commercial decisions before clearance.
• Cooperation obligations. Both parties should commit to preparing and filing the notification promptly, responding to CAK information requests within agreed timescales, and keeping each other informed of material developments in the regulatory process.

What to Do If You Accidentally Close Before Clearance

Closing before receiving CAK clearance under the suspensory regime is a serious compliance failure. The immediate risks include administrative penalties, an order to unwind the transaction (requiring divestiture of the acquired business or shares), and reputational damage that could affect future dealings with the regulator.

If a premature closing occurs, whether through inadvertence, miscalculation of thresholds, or a breakdown in internal compliance processes, the recommended course of action is to self-report to the CAK immediately, file the notification on an expedited basis, and engage experienced Kenyan competition counsel to manage the remediation process. Early and transparent engagement with the regulator is the most effective way to mitigate the severity of any enforcement action. The CAK has discretion in setting penalties, and a cooperative approach is likely to result in a more favourable outcome than if the breach is discovered through the regulator’s own monitoring.

Cross-Border and Multi-Jurisdiction Filings: EAC and COMESA Interactions

Kenya’s reformed regime does not operate in isolation. Transactions with a regional footprint may trigger parallel filing obligations under the COMESA Competition Commission’s merger rules and, increasingly, under the emerging EAC cross-border M&A policy framework. Effective coordination of these filings is essential to avoid delays, conflicting conditions, or enforcement gaps.

Where COMESA and EAC Rules Apply

The COMESA Competition Commission has jurisdiction over mergers that meet its own notification thresholds and involve undertakings operating in two or more COMESA member states. Kenya is a COMESA member, meaning that a cross-border transaction involving Kenyan and, for example, Zambian or Ethiopian operations may be notifiable to both the CAK and the COMESA Commission. The COMESA Practice Note on Mergers clarifies the Commission’s approach to jurisdiction, filing mechanics, and the interaction with national competition authorities. Importantly, the COMESA system also operates on a suspensory basis, and the Commission’s review runs in parallel with, not in place of, the national CAK process.

The EAC cross-border M&A policy, while still evolving, signals a future in which regional coordination mechanisms may formalise the sequencing of national and supra-national filings. Deal teams should monitor developments closely, as the likely practical effect will be additional procedural steps for transactions spanning EAC partner states.

Practical Coordination: Sequencing, Lead Authority, Parallel Filings

For cross-border M&A Kenya transactions, the recommended approach is to map all filing obligations at the outset and designate a “lead authority” strategy. This means identifying which regulator, the CAK, the COMESA Commission, or a neighbouring national authority, is likely to conduct the most extensive review and building the deal timetable around that authority’s timeline. Parallel filings to secondary jurisdictions should be prepared simultaneously so that they can be submitted without delay once the lead filing is lodged. Information sharing between authorities is increasingly common, so consistency across filings is critical, discrepancies between submissions can trigger further enquiries and delay clearance.

Case Example: Multi-Jurisdiction Acquisition

Consider a foreign private equity fund acquiring a logistics group with operations in Kenya, Tanzania, and Uganda. The transaction may be notifiable to the CAK (Kenyan operations), the COMESA Commission (cross-border dimension), and the national competition authorities in Tanzania and Uganda. The fund’s advisers should: (a) conduct a threshold analysis for each jurisdiction simultaneously, (b) prepare a master information pack that can be adapted for each authority’s form requirements, (c) file with all authorities in a coordinated sequence, and (d) designate a single deal-team member responsible for tracking all regulatory timelines and information requests.

Fees, Costs and Timeline Modelling

The revised merger filing fees Kenya 2026 schedule introduces a tiered cost structure that deal teams must budget for early. Below is a modelling framework for three representative transaction sizes, showing the typical fee range, expected clearance timeline, and key considerations.

These figures are indicative and should be verified against the CAK’s current fee schedule at the time of filing. For large transactions, the combined cost of CAK and COMESA filing fees, plus professional advisory fees for preparing market analyses and responding to information requests, can represent a material transaction cost that should be allocated in the deal’s cost-sharing provisions.

Tax Planning and the April 24, 2026 GAAR Decision

The Constitutional Court’s judgment of April 24, 2026 on the application of Kenya’s General Anti-Avoidance Rule (GAAR Kenya 2026) has introduced a new dimension of risk for M&A structuring. The decision clarifies the circumstances in which the Kenya Revenue Authority (KRA) may invoke GAAR to recharacterise transactions that, while legally valid, are structured primarily for the purpose of obtaining a tax benefit. For deal teams, the ruling means that tax-driven structures, including the use of intermediate holding companies, intra-group debt, and the sequencing of asset versus share transfers, must withstand scrutiny under a substance-over-form analysis.

The immediate implications for M&A transactions are significant. Early indications suggest that the KRA will apply the ruling retroactively to transactions that are already structured but not yet completed, and prospectively to all new deals. The ruling’s emphasis on “commercial substance” and the “main purpose” test means that structures designed primarily to minimise withholding tax, capital gains tax, or stamp duty exposure will be vulnerable to challenge unless they can demonstrate a genuine non-tax commercial rationale.

Deal teams should integrate the following five tax due diligence checks into every transaction involving Kenyan assets or revenues:

1. Substance audit. Verify that every entity in the transaction chain, particularly intermediate holding companies, has genuine commercial substance (employees, premises, decision-making authority) beyond the holding of the Kenyan investment.
2. Main purpose test. Document the non-tax commercial reasons for each structural element of the transaction. If a structure element exists primarily to reduce Kenyan tax, consider restructuring or accepting the higher tax cost.
3. Transfer pricing review. Ensure that all intra-group transactions (management fees, interest on shareholder loans, royalties) are priced at arm’s length and supported by contemporaneous documentation.
4. Withholding tax exposure. Map the withholding tax consequences of all cross-border payments arising from the transaction (dividends, interest, management fees) and verify that any treaty relief claimed is supported by the beneficial ownership and substance requirements of the applicable double-taxation agreement.
5. Notification trigger assessment. Consider whether the tax structuring of the transaction, for example, the use of an asset deal versus a share deal to manage stamp duty or capital gains, affects the merger notification analysis. A change in structure may alter the thresholds analysis or the identity of the notifying parties.

Risks, Enforcement and Remedies

The Kenya merger control changes 2026 are backed by a substantially enhanced enforcement toolkit. Understanding the range of consequences for non-compliance is essential for deal teams assessing risk and for boards approving transactions.

Administrative Fines, Unwinding Transactions, and Behavioural Remedies

The CAK’s primary enforcement tools for merger-control violations are administrative penalties and structural remedies. Penalties for failure to notify, or for implementing a merger before clearance, are calculated as a percentage of the merged entity’s annual turnover in Kenya, a formula that can produce very substantial fines for large businesses. In addition, the CAK has the power to order the unwinding of a completed merger, requiring divestiture of acquired assets or shares and the restoration of the pre-merger market structure. Where full divestiture is disproportionate, the CAK may impose behavioural remedies, conditions on the merged entity’s future conduct, such as requirements to maintain separate brands, continue supplying competitors, or refrain from bundling products.

Criminal or Civil Exposure

Beyond administrative enforcement, the Competition Act provides for criminal sanctions in cases of wilful non-compliance, including the potential for personal liability of directors and officers who authorised or permitted the breach. Civil exposure also arises: competitors, suppliers, or customers who suffer loss as a result of an anti-competitive merger may bring private damages claims. The combined effect of administrative, criminal, and civil risk means that non-notification is a commercially unacceptable strategy under the reformed regime.

How to Run a Remedial Programme If CAK Opens an Investigation

If the CAK initiates an investigation into a potential merger-control breach, the most effective response is immediate, structured cooperation. This should include: (a) appointing dedicated Kenyan competition counsel to interface with the CAK, (b) conducting an internal audit to establish the facts and timeline, (c) preserving all relevant documents and communications, (d) preparing a comprehensive remediation proposal (which may include retrospective notification, proposed commitments, or structural remedies), and (e) engaging with the CAK proactively to demonstrate good faith and minimise the severity of any penalty.

5-Step Action Plan for Buyers, Sellers and Advisers

1. Screen every transaction against revised thresholds, responsibility: GC / deal team lead. Run the combined turnover and asset test at the earliest stage of deal planning.
2. Build CAK review time into the deal timetable, responsibility: buyer / sponsor. Set the longstop date to accommodate Phase II review as a base case.
3. Prepare the filing pack in parallel with transaction documentation, responsibility: external counsel. Begin drafting the CAK notification form and assembling supporting documents at the same time as negotiating the SPA.
4. Integrate GAAR tax due diligence into the workstream, responsibility: tax adviser. Apply the five-point substance and purpose checklist to every structural element of the transaction.
5. Map all cross-border filing obligations, responsibility: GC / regulatory counsel. Where the transaction has an EAC or COMESA dimension, prepare parallel filings and designate a lead-jurisdiction strategy before signing.

Reporting Obligations by Entity Type

These obligations apply equally regardless of whether the transaction is structured as a domestic deal or a cross-border M&A Kenya transaction. Where uncertainty exists about whether a particular transaction falls within the notification obligation, the recommended approach is to engage with the CAK for pre-notification guidance or to file on a precautionary basis.

Resources and Next Steps
