Michael-James Currie, director at Primerio, hosted an insightful webinar alongside Primerio’s in-country Partners, Mweshi Bunda Mutana for Zambia, Hyacinthe Fansi for Cameroon, and Cris Mwebesa for Tanzania. The conversation provided an extensive look into recent developments in merger control across Africa’s principle regional competition authorities and can be accessed here.

This deep dive showed a significant shift towards a more prominent enforcement, lower notification thresholds and stronger coordination between national and supranational regulators. Africa’s merger landscape has vastly changed over the past four to five years which has resulted in more complexity in multi-jurisdictional merger control, increased detection risk for non-notified transactions and a widened the set of jurisdictions that must now be considered for compliance.

This webinar session contained a slightly different focus as the inspiration for the session was to feature a more pragmatic approach that stems from how merger control has changed significantly in Africa over the past few years. There has been a very clear shift in merger regulation and an increase of agencies that have adopted merger control or antitrust laws more generally. The rules and regulations surrounding merger control have become more sophisticated, and these developments are important for the agencies that make use of merger control, antitrust compliance and enforcement. As a result, it was highlighted that the CEMAC merger control has evolved from a basic framework to a more formalised and substantive merger control regime. This is evident in how the system now imposes mandatory filings when both turnover and market share thresholds are met, even for foreign deals without substantial local operations. The system does remain very paperwork-heavy, and a growing concern is the high filing fee cap that is c. USD 70 million.

COMESA was described as Africa’s most advanced and prominent regional regulator in respect of merger control and is now preparing to make substantial amendments to its merger regulators which are expected to take effect in the beginning of 2026. These changes will include mandatory notification for greenfield joint ventures, provisions on digital markets, provisions relating to public interest considerations and questions regarding how regional and national priorities will be remedied.

The East African Community Competition Authority has now operationalised its merger control system, effective as of 1 November 2025. This regime has exclusive jurisdiction over mergers with cross-border effects involving at least two partner states, stated by Cris Mwebesa, and meeting a certain asset or turnover threshold of USD 35 million. The system includes a 120-day review period and filing fees, however several Member States have not domesticated this regional law which means that filings at a national level in parallel to the regional level should be expected. This means that there will be overlaps with COMESA and there is a lack of clarity on how the public’s interest will be prioritised which creates further confusion and uncertainty. Confusion can arise when, for example, Zanzibar’s separate competition authority adds an additional filing requirement for merger control.

The ECOWAS Competition Authority has been operational for around one year and has demonstrated steady progress in handling non-contentious mergers. This authority considers transactions at certain turnover levels and individual thresholds which renders the regime broad in scope. The jurisdictional thresholds for an ECOWAS filing remain low, which may result in challenges around when a dual filing is appropriate and delaying decision making by the respective authorities.

Evidently, across many jurisdictions there are varying levels of institutional maturity that influence regional merger control. This is seen in how Zambia has strengthened its relationship with COMESA, following recent domestic legislative amendments, whilst Tanzania’s national authority co-exists with emerging EAC obligations, creating an emphasised need for coordination. These national-regional intersections will continue to influence filing strategies, especially in sectors where public interest or national sensitivities are emphasised.

These insightful discussions highlighted that merging parties now face a more complex and differentiated compliance across Africa. Although procedural clarity continues to develop, the direction of development is clear in that African merger regimes are growing more enlightened, more interrelated and more aligned with global standards.
