The ownership transfer was finalised on May 26, marking the end of a 32-year association that began in 1992, shortly after Angola’s civil war subsided. Alrosa had steadily increased its shareholding over the years, reaching 41% in 2018.

The move comes after mounting political and regulatory tensions. In November 2024, Angola’s Minister of Mineral Resources, Diamantino Azevedo, had publicly labelled Alrosa a "toxic partner" amid ongoing international sanctions against the Russian company.

With the exit complete, Angola’s state-owned diamond company Endiama EP now holds a controlling 59% in Catoca, while Taadeen takes over the remaining 41%. Catoca’s updated website reflects the new shareholder structure.

Financial terms of the deal have not been disclosed.

The shift aligns with Angola’s broader push to diversify international partnerships and reposition its mining industry as a more transparent and globally integrated sector.
