On 13 January 2026, the newly renamed COMESA Competition and Consumer Commission (“CCCC”) issued its Practice Note 1 of 2026 (“Practice Note”), which is intended to provide legal clarification for businesses and legal communities regarding the newly approved COMESA Competition and Consumer Protection Regulations of 2025 (“2025 Regulations”).
By addressing common points of confusion, such as clarification on the commencement of the 2025 Regulations, merger thresholds in respect of transactions in digital markets, and the CCCC’s ability to grant derogations from its suspensory regime, the CCCC aims to ensure a uniform interpretation and a smooth transition to the 2025 Regulations and new suspensory merger regime.
The effective date and “in-flight” transactions
One of the main objectives of the practice note was to correct a previous administrative error regarding the implementation date of the new regime. The CCCC clarified that the effective date of the 2025 Regulations is 4 December 2025, the same date the 2025 Regulations were approved by the COMESA Council of Ministers.
For merger transactions signed shortly before the enforcement of the 2025 Regulations, but were not yet notified or closed, the CCCC has set a clear boundary stating that any matter not under assessment by the CCCC by 4December 2025 will be governed by the 2025 Regulations. Contrarily, any matters instituted before 4 December 2025 and currently under the CCCC’s review will continue to be managed under the repealed 2004 Regulations to ensure procedural continuity.
Strict adherence to the new suspensory regime
The Practice Note emphasises and enforces the CCCC’s new suspensory regime, requiring notifiable transactions to be approved by the CCCC before they may be implemented.
While the 2025 Regulations allow for derogations where parties may apply to implement transactions prior to obtaining approval, the CCCC emphasises that such derogations will be granted sparingly and only in exceptional circumstances.
The CCCC, however, clarifies that while there is no longer a deadline by which a transaction must be notified to the CCCC, there are no derogations afforded to the notification requirements themselves. This ensures that all notifiable mergers must be notified prior to implementation.
Transactions in digital markets
To ensure the CCCC keeps pace with the rapid development of antitrust enforcement in digital markets, the 2025 Regulations have introduced a specific digital-transaction value threshold in an attempt to regulate big tech.
Under the 2025 Regulations, a transaction involved in digital markets is required to be notified should:
the worldwide value of the transaction reaches over COM$250 million (US$250 million); and
at least one party operates in two or more Member States.
Notification requirements in respect of Joint Ventures
When considering the notification requirements and thresholds in respect of a joint venture (“JV”), the CCCC has emphasised that the 2025 Regulations will only apply to JVs that have the intention of performing on a lasting basis all the functions of an autonomous economic entity (commonly referred to as full-function JVs).
A keynote emphasised by the Practice Note is the definition of a “lasting basis”, emphasising that a JV is not subject to notification if the parties to the JV do not have the intention of operating within the COMESA region within the next three years or, once established, operating for a period of three years or more.
Extension of merger assessments to non-competition factors
Although the CCCC considers public interest factors under the 2025 Regulations, the Practice Note has clarified that the competition concerns of a transaction carry the most weight in its investigation.
The CCCC priorities ensure that in the future, it is unlikely for the Commission to reject a co-competitive merger based on negative public interest. This is just as a merger that may significantly lessen a competitive market will not be more heavily considered based on the benefits of the public interest.
John Oxenham, director at Primerio International, notes that “ultimately, while the effects of the 2025 Regulations and Practice Note remain to be seen in practice, the Practice Note acts as a helpful road map for navigating the new aspects of the 2025 Regulations.” His colleague Andreas Stargard observes that the latest Practice Note is “not substantive in any significant way, but truly sticks to the theme of mere ‘clarification’ of the existing new 2025 Regs. Deadlines and time calculations are explained in more detail than in the statute — but not altered — and value thresholds for digital transactions are clarified (again, without substantively modifying the text as found in the new law). They are basic practice pointers, no more and no less.”
On 4 December 2025, the COMESA Council of Ministers adopted the COMESA Competition and Consumer Protection Regulations, 2025 (the “2025 Regulations”), marking a significant overhaul of its regional regime since its inception in 2004. The 2025 Regulations, which entered into force immediately, officially repeal and replace the previous COMESA Competition Regulations (the “2004 Regulations”).
The 2025 Regulations have introduced a number of substantive developments and refinements to the COMESA competition regime. Most significantly, the 2025 Regulations have have introduced a suspensory merger control regime, expand a number of enforcement powers, formalise a leniency regime in respect of hardcore carte conduct and significantly strengthen oversight of digital markets.
The “Quad-C”: COMESA Competition Commission has also been rechristened as the COMESA Competition and Consumer Commission (“CCCC”), reflecting its enhanced consumer protection mandate.
“The 2025 Regulations have not come as a surprise,” according to competition-law practitioner Michael-James Currie. As AAT has previously reported, the COMESA Competition Commission had on 24 January 2024 issued a press release requesting comments to its proposed Draft Regulations (as amended in November 2023). “As such, the 2025 Regulations have been contemplated, revised and tightened alongside a number of stakeholders and comments over a period of at least two years, including our and our clients’ input,” says Currie. The 2025 Regulations have also been coupled with an updated set of implementing Rules. Finally, the CCCC recently introduced a Practice Note regarding the new merger control regime.
We report comprehensively on these significant developments here, as well as in a series of future COMESA updates. For an academic review of the “coming of age” of the COMESA enforcement regime, please see Dr. Liat Davis and Andreas Stargard‘s separate Concurrences article, “COMESA: Regional Rapprochement Refined“, tracing the trajectory of the Common Market for Eastern and Southern Africa (COMESA) competition regime—the first multi-national antitrust enforcement system in Africa, and the second to be created globally after the European Union, in what has since become a growing field of regional enforcement regimes.
COMESA’s move to a suspensory regime & expanded merger assessment powers
“One of the most significant changes is the move to a suspensory merger control regime. Under the 2004 Regulations, merging parties could implement transactions notified in COMESA prior to obtaining clearance, provided such transactions were notified within 30 days of the ‘decision to merge’,” according to Primerio partner John Oxenham. “This is no longer the case: notifiable mergers must now be approved either unconditionally or conditionally by the CCCC prior to implementation.”
The 2025 Regulations have, however, introduced a derogation in respect of the suspensory rule, which provide a level of flexibility on the suspensory rules for parties involved in public takeovers, for example.
The Regulations also revise the definition of a ‘merger’ – introducing further clarifications on ‘controlling interest’ and explicitly capturing full-function joint venture arrangements – as well as introducing updated financial thresholds.
Dr. Mwemba, CEO of the CCCC
Transactions which meet the ‘merger’ definition will now be notifiable where the combined turnover or asset value of the parties in the Common Market equals or exceeds COM$60 million (US$60 million), and at least two parties each meet the COM$ (US$10 million) threshold. For certain digital market transactions, a new transaction-value threshold of COM$250 million (US$250 million) has been introduced.
In addition, the maximum merger filing fee cap has now been increased from COM$200,000 to COM$300,000.
The CCCC’s merger assessment powers have been broadened beyond the traditional lessening of competition (“SLC”) test. Borrowing from a number of African competition authorities’ precedent, the CCCC may now also consider specific public interest factors in merger control, including employment, the competitiveness of small and medium enterprises, environmental sustainability and effects on innovation in the Common Market.
Jurisdictional reach & Strengthening the COMESA one-stop shop
The 2025 Regulations reinforce COMESA’s ‘one-stop shop’ principle. COMESA Member States are now under stronger obligations not to require parallel merger notifications where a transaction falls within the jurisdiction of the CCCC. This provides greater legal certainty for merging parties operating across multiple COMESA Member States. That said, “some obstacles to a full one-stop-shop do remain,” according to Andreas Stargard. “Dr. Willard Mwemba, the CCCC’s CEO, noted at last year’s fall press conference that, in light of the newly-established EAC competition regime and its somewhat overlapping merger notification requirements, the Commission acknowledges the concern that dual notification obligations may occur in the foreseeable future due to the parallel regional body.”
For completeness, the COMESA Common Market comprises 21 Member States – Burundi, Comoros, the Democratic Republic of Congo, Djibouti, Egypt, Eritrea, Eswatini, Ethiopia, Kenya, Libya, Madagascar, Malawi, Mauritius, Rwanda, Seychelles, Somalia, Sudan, Tunisia, Uganda, Zambia, and Zimbabwe.
Anti-competitive Practices
New standards and risks in respect of per se prohibitions
The 2025 Regulations overhaul the CCCC’s approach to restrictive practices. While the 2004 Regulations’ standard was related to having an ‘appreciable effect’, the general prohibition now applies to conduct that has the object or effect of resulting in an SLC in the Common Market.
The list of per se prohibitions has also been expanded. Certain vertical restraints – including absolute territorial restrictions, restrictions on passive sales and minimum resale price maintenance – are now prohibited outright and cannot be justified by efficiency defences.
Formal introduction of a leniency regime
One of the major developments flowing from the 2025 Regulations is the introduction of a formal leniency regime for hardcore cartel conduct occurring within the Common Market.
Importantly, any leniency decisions taken by the CCCC will officially bind individual COMESA Member States, meaning that leniency applicants will not be subjected to parallel enforcement at a national level for the same conduct reported. This significantly enhances legal certainty and aligns COMESA with international best practice.
Higher penalties and greater enforcement
Administrative penalties have been substantially increased by the 2025 Regulations. Under the 2004 Regulations, fines were capped at COM$200,000, the CCCC may now impose fines of up to 10% of a firm’s turnover in the COMESA Common Market. This change, coupled with the expanded per se prohibitions, signals a clear intention of the CCCC to strengthen enforcement and deterrence of anti-competitive practices.
Abuse of dominance and economic dependence
The definition of dominance has been revised, with a stronger focus on economic independence from competitors, customers and suppliers. While no bright-line market share thresholds are introduced by the 2025 Regulations, the broader definition may give rise to increased litigation and uncertainty.
The 2025 Regulations also introduce a new prohibition on the abuse of economic dependence which targets situations where a firm exploits a superior bargaining position over a counterparty that lacks reasonable alternatives, even where the firm is not dominant.
Increased focus on digital markets and gatekeepers
In line with international trends and standards, the 2025 Regulations introduce the concept of ‘gatekeepers’ in digital markets. Gatekeepers are subject to a wide range of behavioural prohibitions, including bans on self-preferencing, data leveraging, anti-steering provisions and discriminatory treatment of small and medium enterprises.
While the criteria for identifying ‘gatekeepers’ remain vague, the scope of the obligations is broad and signals a far more interventionist approach to digital markets in the COMESA Common Market than anticipated previously.
Enhanced market inquiry powers
The CCCC’s investigative powers have been broadened to include the ability to conduct market inquiries and allow the CCCC to compel information and take action, including launching official investigations, engaging in advocacy or negotiating potential remedies.
Importantly, the CCCC cannot unilaterally impose remedies on parties following a market inquiry alone.
Conclusion
The 2025 Regulations represent a major evolution in the COMESA competition framework. As the authors conclude in their Concurrences article cited above, “[t]hese reforms expand the CCC’s toolkit—introducing suspensory merger control, cartel leniency, market inquiries, and digital-market provisions—while also placing public interest and consumer rights more explicitly into the regional framework. They are ambitious, progressive, and aligned with global trends, yet they also raise difficult questions of clarity, implementation, and institutional capacity.”
In AAT’s view, provided adequate staffing and resources exist, the CCCC has now become one of the best-equipped regional competition regulators on the African continent.
Much will depend on how the 2025 Regulations are implemented in practice. For now, companies operating in the COMESA region should consider the 2025 Regulations in line with their compliance strategies and, if in doubt, seek professional legal advice to tailor their business practices and corporate strategies accordingly.
