Gabonese group Holding ACK S.A. announced on April 19, 2026, the signing of an agreement to acquire 90% of Colas Gabon's capital from Colas International. The Gabonese state will retain its existing 10% stake. This acquisition is expected to structurally reconfigure Gabon's public works and construction sector, which has long been dominated by a few foreign operators. Colas Gabon, established in the country for decades, employs 254 people, mostly Gabonese, and possesses an integrated industrial infrastructure including quarries, aggregate production, asphalt plants, and quality control laboratories. Holding ACK, led by Alain-Claude Kouakoua, has committed to ensuring operational continuity, maintaining all jobs, and preserving client and partner relationships. This acquisition goes beyond a simple asset transfer. For decades, Colas reportedly refused to sell aggregates, bitumen, and asphalt to competing companies, including Gabonese SMEs. The road construction market was effectively controlled by an oligopoly of four or five foreign majors who "discreetly" divided state tenders. Holding ACK intends to change this dynamic by selling its materials to any solvent operator, thereby opening access for small and medium-sized Gabonese construction companies. The stated ambition is also to reduce the cost per kilometer of road, currently influenced by opaque pricing structures inherited from this de facto arrangement. Holding ACK, already active in public works, hydrocarbon transport
