Merger Control in Uganda 2026: Thresholds, Filing Process and Timelines

Merger control Uganda is entering a decisive phase in 2026 as the country’s competition regime moves from statutory text to active enforcement, raising the stakes for any transaction with a Ugandan nexus. Uganda enacted the Competition Act, 2024, which, together with its regulations, provides the framework for reviewing anti-competitive conduct and, in due course, transactions affecting Ugandan markets. For in-house counsel, private equity and venture capital investors, acquirers and target boards, the practical questions are immediate: does your deal require notification, can you close before clearance, and how long will the regulator take?

This guide answers those questions with a transaction-focused lens, explaining the thresholds that may trigger a filing, the suspensory rules that govern closing, the mechanics of preparing a notification, realistic timelines, and how a Ugandan filing interacts with COMESA and East African Community regimes. It is written for deal teams who need clarity and a workable checklist rather than abstract commentary.

Quick answers on merger control Uganda

The following short answers address the most common questions deal teams ask before committing to a transaction. Each is expanded in the sections below, with statutory and institutional references set out in the Sources section. Because Uganda’s competition framework is relatively new and its implementing machinery is still being operationalised, the prudent course is to verify each point against the current legislation and any regulations, and to engage the responsible authority directly.

• Is notification mandatory? Where a transaction meets the applicable thresholds set under Uganda’s competition framework, notification to the responsible competition authority is required before implementation. Treat the regime as suspensory unless counsel confirms otherwise for your specific deal.
• Can you close before clearance? For a notifiable transaction operating under a suspensory regime, parties should not implement the deal until clearance is obtained. Closing prematurely exposes the parties to penalties and the risk that the transaction is unwound.
• What triggers a filing? Turnover and asset tests measured against the parties’ most recent financial year, with group attribution rules bringing in the wider corporate group. Confirm the precise triggers against the Competition Act and its regulations.
• Do cross-border deals need COMESA too? A transaction with a regional dimension may be caught by the COMESA merger-control regime in addition to, or instead of, a national filing. Confirm both at the outset to sequence filings correctly.

Because published regulator guidance on several operational points remains limited, pre-filing engagement with the competition authority is strongly recommended for any transaction close to the thresholds.

Legal framework and authorities

Uganda’s competition regime is anchored in the Competition Act, 2024, which establishes the substantive prohibitions on anti-competitive conduct and the framework for reviewing mergers and acquisitions. The statute and any amending legislation or regulations are the primary reference point for thresholds, the notification obligation and the consequences of non-compliance, and the authoritative text should be taken from the Parliament of the Republic of Uganda and the relevant ministry. The practical significance of 2026 is operationalisation: the shift from legislation on the page to a functioning review process.

For deal teams, this means that assumptions formed before the regime became active, that filings were theoretical or rarely enforced, can no longer be relied upon, and that the operational detail (including the designated administering body and procedures) should be confirmed before structuring a deal.

Because competition policy in Uganda sits within a broader regional and international context, understanding the framework also requires awareness of the COMESA and East African Community competition instruments, and of comparative best practice developed through bodies such as UNCTAD’s competition and consumer protection programme. These inform how Uganda’s authorities interpret and apply their own rules.

Who enforces merger control in Uganda?

Merger control Uganda is administered by the authority designated under the Competition Act and its regulations, responsible for reviewing notifications, assessing the competitive effects of transactions, and issuing clearances, conditional approvals or prohibitions. Enforcement typically operates alongside an adjudicative or appellate route, a tribunal or court, that hears appeals from the authority’s decisions and, in contested matters, adjudicates disputes over clearance conditions or penalties. Deal teams should identify the correct filing office and the appeal route early, as the structure determines where submissions are lodged and how adverse decisions can be challenged. Because the administering body and its procedures are still being established, counsel should confirm the current filing channel directly before preparing a submission.

Primary statutory provisions to know

Three categories of provision drive transaction planning. First, the notification provisions, which define what constitutes a notifiable merger and impose the obligation to notify before implementation. Second, the threshold provisions, which set the turnover and asset tests that determine whether a transaction is caught. Third, the suspensory provisions, which prohibit implementation of a notifiable merger before clearance and set out the consequences of breach. Any transaction analysis should begin by mapping the deal against each of these, citing the relevant sections of the Competition Act and its regulations. Where the statutory wording is ambiguous or implementing regulations are silent, the prudent course is to treat the transaction as potentially notifiable and seek confirmation from the authority.

Merger filing thresholds in Uganda

The filing thresholds are the first gate every deal must pass through. Under Uganda’s competition framework, notifiability is assessed against financial tests, typically turnover and asset-based measures, applied to the parties and their wider corporate groups, as prescribed by the Competition Act and its regulations. The thresholds determine whether a transaction is a compulsory notification or falls below the line and may proceed without a filing. Getting this calculation right is critical: an incorrect conclusion that a deal is below the threshold can result in an unlawful, unnotified merger with all the enforcement risk that follows.

Several principles typically govern the calculation. Turnover and assets are generally measured by reference to the most recent completed financial year, converted into the relevant currency where a party reports in a foreign currency. Group attribution rules commonly mean the figures are not limited to the immediate contracting entities; the turnover and assets of controlling and controlled entities across the group may be aggregated, so a modest local target controlled by a large multinational acquirer can meet the thresholds through the acquirer’s global or regional figures. This is why foreign-to-foreign transactions with even a limited Ugandan footprint can be caught.

Because the precise numerical thresholds and the exact measurement basis are set by the statute and its implementing regulations, deal teams should verify the current figures against the authoritative legislative text before concluding on notifiability. Where the threshold is close, build the filing timeline into the deal programme on a precautionary basis.

How to calculate turnover and assets: worked examples

Consider two illustrative scenarios. In the first, a Ugandan logistics company (the target) with annual turnover equivalent to a mid-market domestic business is acquired by another Ugandan group. Both parties’ turnover and asset figures are taken from their most recent audited financial statements. The combined and individual figures are compared against the statutory thresholds; if the applicable test is met or exceeded, the transaction is notifiable and the parties must file before closing.

In the second scenario, a foreign technology company acquires another foreign company, where the target supplies services to Ugandan customers generating turnover attributable to Uganda. Even though neither party is incorporated in Uganda, group attribution and local-nexus considerations may bring the transaction within merger control Uganda if the parties’ turnover or assets, measured on the statutory basis, cross the thresholds and there is a sufficient connection to the Ugandan market. The practical lesson is that nexus and group figures, not the location of incorporation, tend to decide notifiability. In both cases, the calculation should be documented contemporaneously so the analysis can be shown to the authority if queried.

De minimis thresholds and exclusions

Not every corporate change is a notifiable merger. Transactions that do not result in a change of control, for example, the acquisition of a minority stake that confers no decisive influence, generally fall outside merger control. Internal group reorganisations that do not alter ultimate control may also be excluded. Full-function joint ventures, by contrast, can themselves constitute notifiable transactions where they meet the thresholds and bring about a lasting change in market structure. Because the boundary between a controlling and non-controlling acquisition can be finely balanced, and because published guidance on these categories may be limited, counsel should assess control on the facts and, where there is doubt, engage the authority before deciding not to file.

Is notification mandatory? Suspensory regime and closing rules

For transactions that meet the thresholds, notification under Uganda’s competition framework is compulsory, not optional. The regime should be treated as suspensory: a notifiable merger should not be implemented until clearance has been granted. This suspensory character is a critical operational feature for deal teams, because it directly affects the deal timetable and the choice of signing-to-closing structure. Parties cannot sign today, close tomorrow and notify afterwards in the hope of retrospective approval; the obligation bites before completion.

The consequences of ignoring the obligation can be significant. An unnotified or prematurely implemented merger may be exposed to financial penalties, and the authority may have powers to require the transaction to be unwound or to impose interim measures pending review. For acquirers, this translates into real deal risk, the possibility that a completed acquisition is reversed, or that penalties erode the economics of the transaction. Prudent practice is therefore to build clearance into the conditions precedent and to defer completion until the authority has cleared the deal.

Penalties and remedies

Breach of the notification and suspensory obligations can attract penalties under the Competition Act, which may include fines calibrated to the seriousness of the breach and, potentially, orders affecting the validity or implementation of the transaction. The authority or tribunal may also have power to impose behavioural or structural remedies where a merger raises competition concerns, ranging from divestitures to conduct commitments. Because the precise penalty levels and remedial powers are set by statute, the exposure should be confirmed against the current legislative text and factored into the risk allocation between buyer and seller in the transaction documents.

Interim measures and enforcement trends in 2026

As the regime is operationalised through 2026, observers anticipate increased scrutiny of transactions affecting Ugandan markets and greater willingness to use the authority’s investigative and interim powers as the institutional framework matures. The likely practical effect is that deal teams should not assume a light-touch or purely formal review. Interim measures, orders preserving the status quo while the authority examines a deal, are a particular risk for parties who move quickly. The most effective ways to manage enforcement risk in the current environment are to engage the authority proactively, file complete submissions, and avoid any step that looks like premature implementation.

Merger notification Uganda: step-by-step filing checklist

A well-prepared merger notification Uganda filing accelerates review and reduces the risk of deficiency queries that stall the clock. Exact form names and annex requirements should be confirmed with the authority and against the implementing regulations; the following documents and steps are typically required or advisable:

1. Executed or near-final transaction agreement, the sale and purchase agreement, shareholders’ agreement or merger agreement evidencing the structure and the change of control.
2. Financial statements, the most recent audited accounts of the parties and their groups, supporting the turnover and asset calculations used to establish notifiability.
3. Market information, a description of the affected markets, the parties’ activities, market shares and principal competitors, enabling the authority to assess competitive effects.
4. Corporate and control information, group structure charts showing ownership and control before and after the transaction.
5. Supporting affidavits or declarations, where required to verify the accuracy of submissions.
6. Filing fee payment, evidence of payment of any applicable filing fee through the prescribed mechanism.
7. Confidentiality claims, clearly marked confidential annexes with a non-confidential version for any public element of the process.

Confirm at the outset whether the authority accepts electronic or paper submissions, the required language of documents, and whether certified translations are needed for foreign-language agreements. Lodging a complete, internally consistent filing is the surest way to keep the review on track.

Timeline to prepare the filing

Preparation time is often underestimated. Before a notification can be lodged, the parties must complete sufficient due diligence to describe the affected markets accurately, assemble group financials, finalise or sufficiently advance the transaction documents, and obtain internal approvals to disclose commercially sensitive information. For a straightforward domestic deal, allow two to four weeks to compile a complete filing; for a complex cross-border transaction with multiple affected markets, four to eight weeks is more realistic. Building this preparation window into the overall deal programme, rather than treating the filing as an afterthought once the agreement is signed, prevents the notification from becoming the critical path to completion.

Common deficiencies and how to avoid them

Filings most often stall because of incomplete market definitions, inconsistent turnover figures between the notification and the underlying accounts, missing group structure information, or inadequately substantiated confidentiality claims. Each deficiency risks the authority stopping or resetting the review clock while it requests further information. To avoid this, reconcile every figure to its source, provide clear market-share evidence, submit a complete group chart, and prepare both confidential and non-confidential versions of sensitive documents from the start. Where the authority’s requirements are not fully published, a short pre-filing consultation can surface expectations before the formal submission is made.

Merger approval timeline Uganda: realistic calendar and procedural stages

Merger review in many jurisdictions follows a two-phase structure: an initial review in which the authority assesses whether the transaction raises competition concerns, and, where it does, a more detailed in-depth review. The statutory clock usually begins once a complete notification is accepted, which is why a deficient filing that triggers information requests can extend the real-world timeline well beyond the headline statutory period. Deal teams should plan to a realistic calendar, not a theoretical minimum, and should confirm the applicable review periods against the Competition Act and its regulations.

Where Uganda’s procedural timelines and multi-phase structure are prescribed by the Competition Act and its implementing regulations, those periods govern. As a general planning assumption pending confirmation of the applicable statutory windows, treat any published review period as a floor rather than the expected duration, and allow additional time for information requests, remedies negotiation or market testing in more complex matters. Where exact statutory review windows are not confirmed, build a conservative buffer into the deal programme and confirm the current periods with counsel before relying on any specific figure.

The practical calendar runs from day zero, the date a complete filing is accepted, through the initial review period, to either a clearance decision or a referral to any in-depth phase. Co-ordinate the Ugandan timeline with any parallel COMESA review so that the deal’s longest-pole clearance governs the completion date. A simple domestic deal might run: preparation two to four weeks; filing accepted on day zero; initial clearance within the applicable statutory period. A complex cross-border deal might run: preparation four to eight weeks; filing accepted on day zero; initial review followed by referral to any in-depth review; clearance or conditional clearance after an extended period. Confirm all periods against the authoritative legislative text.

Fees, confidentiality and public notice

Filing fees, where applicable, are set by statute, regulations or ministerial instrument and are payable through the prescribed channel; evidence of payment typically accompanies the notification. Confirm the current fee basis, whether a flat fee or a scale, against the authoritative source before budgeting the transaction. Confidentiality is a central concern for deal teams: notifications contain commercially sensitive information, and parties should mark confidential material clearly and, where the process involves any public element, prepare a non-confidential version. Any public notice requirement should be identified early so that the timing of disclosure is managed alongside the parties’ own announcement strategy and any securities-law obligations.

Interaction with COMESA and EAC regional regimes

Cross-border deals raise the question of whether a national filing, a COMESA merger control filing, or both are required. The COMESA competition regime applies to transactions with a regional dimension affecting the common market, assessed against its own thresholds and triggers, administered through the COMESA Competition Commission. The East African Community competition framework provides a further regional layer relevant to deals affecting the EAC market. The core planning task is to map the transaction against each regime at the outset and to determine which filings are mandatory and how they interact.

A key issue is the relationship between a COMESA filing and a national filing in a COMESA member state. Where a transaction meets the COMESA thresholds and affects the regional market, a COMESA notification may be required, and parties must consider whether a separate national filing is also needed or whether the regional filing covers the regional dimension. Getting the sequencing and precedence right avoids duplicate work and inconsistent timelines. Where both regimes apply, co-ordinate the filings so that the parties are not cleared in one forum while implementation remains prohibited in another.

The table below summarises, at a high level, how merger control Uganda compares with the COMESA and EAC regimes. The figures and characteristics should be confirmed against the authoritative sources for each regime before relying on them in a transaction.

Strategic deal drafting and transactional safeguards

Because merger control Uganda is suspensory, the transaction documents must manage the gap between signing and clearance. Several drafting tools address this risk. Make regulatory clearance an express condition precedent to completion, so that the parties are not obliged to close until the authority has cleared the deal. Allocate responsibility and cost for making the filing and for pursuing clearance, including an obligation on the acquirer to use defined efforts to obtain approval. Where the parties wish to progress integration planning, use hold-separate covenants to keep the businesses operationally independent until clearance, avoiding any step that could be characterised as premature implementation.

Consider a long-stop date that accommodates a realistic clearance timeline, including the possibility of an in-depth review, and provide for termination or price adjustment if clearance is refused or delayed. Escrow and staggered or conditional closing structures can protect value where clearance is uncertain. In cross-border deals, align the conditions precedent across all required regulatory filings so that completion is triggered only when every mandatory clearance, Ugandan and regional, is in hand.

Practical examples and case studies

Two anonymised illustrations show how the regime works in practice. In the first, a domestic acquisition of a Ugandan services business by another local group met the thresholds through the combined turnover of the parties. The acquirer built clearance into the conditions precedent, filed a complete notification shortly after signing, and obtained clearance in the initial review phase without conditions. Completion followed promptly once clearance was confirmed, a clean outcome driven by early preparation and a complete filing.

In the second, a cross-border acquisition of a group with activities across several markets triggered a COMESA filing and consideration of national filings. The parties mapped the regimes at the outset, sequenced the filings, and used hold-separate covenants to maintain operational independence while the reviews ran in parallel. The in-depth phase extended the timeline, but co-ordinated management of the regional and national processes allowed the parties to complete once the longest-pole clearance was obtained. The lesson across both cases is that timeline discipline and early regulatory mapping determine whether clearance is a routine step or a deal-threatening obstacle.

Conclusion and next steps

Merger control Uganda has become a live operational concern for anyone transacting with a Ugandan nexus in 2026, and the margin for treating notification as a formality has narrowed as the Competition Act is operationalised. Deal teams should begin every transaction by mapping it against the thresholds, confirming whether the suspensory obligation applies, preparing a complete filing early, and co-ordinating any COMESA or EAC filings so that completion follows the longest-pole clearance. Build regulatory clearance into the conditions precedent, use hold-separate and conditionality drafting to manage the gap between signing and completion, and engage the authority proactively where guidance is limited. For transaction-specific advice, consult qualified Ugandan corporate competition counsel before committing to a deal structure.
