French line CMA CGM now controls nearly 89.5% of Swiss group CEVA Logistics following a tender offer.
The shipowner is paying CHF 30 ($30.25) per share to raise its holding from 33% in a deal valuing the logistics player at $1.66bn.
An additional acceptance period will begin on 20 March and run until 2 April.
CMA CGM also announced new partnerships in Ethiopia.
It is creating a maritime agency and participating in the development of a dry port in Modjo.
CEO Rodolphe Saade signed a deal this week.
The idea is to make the terminal the hub of a regional network covering the country’s logistics corridors.
