In a long-anticipated move towards deeper regional integration and harmonised competition oversight, the East African Community Competition Authority (“EACCA”) has formally announced that it will begin receiving and reviewing merger and acquisition notifications with cross-border effects as of 1 November 2025. 

This marks a significant implementation milestone under the East African Community Competition Act, 2006, which established the EACCA as the supranational body responsible for enforcing competition policy among the eight EAC Partner States. These Partner States are the Republic of Burundi, the Democratic Republic of Congo, the Federal Republic of Somalia, the Republic of Kenya, the Republic of Rwanda, the Republic of South Sudan, the Republic of Uganda and the United Republic of Tanzania. 

Notably, on 10 June 2025, the COMESA Competition Commission (“CCC”) and the EACCA signed a Memorandum of Understanding (“MOU”) aimed at strengthening collaboration between the two agencies. With six of the eight East African Community (“EAC”) Partner States also being members of COMESA, the MOU seeks to minimise potential duplication in enforcement, while promoting joint advocacy efforts and an enhanced legal certainty and predictability for businesses operating across the region. 

Under the newly effective merger control framework, a transaction must be notified to the EACCA if the combined turnover or assets (whichever is higher) of the merging entities in the EAC equals or exceeds USD 35 million, and at least two of the undertakings have a combined turnover or assets of USD 20 million in the EAC, unless each achieves at least two-thirds of its aggregate turnover or assets in the same Partner State. 

Importantly, once a qualifying transaction is notified to the EACCA, there is no requirement to file with national competition authorities, thereby streamlining the merger review process for regional transactions. Merger notifications will be subject to fees ranging from USD 45 000 to USD 100 000, based on the size of the transaction. 

While the EACCA’s enforcement powers have been active in areas such as restrictive business practices, the operationalisation of merger control fills a long-standing gap in this regional competition regime. It also brings the EAC in line with other regional economic communities like the CCC and ECOWAS Regional Competition Authority (“ERCA”), which already exercise merger control functions. 

Firms with pending or planned transactions in the region should prepare to engage with the Authority under this new regime, ensuring timely filings and compliance from November onwards.
