De Post-La Poste, Belgium's national postal operator, acquired a majority stake in MSI Worldwide Mail, a U.S.-based mail and parcel delivery company.
The company did not say how much it paid for the outstanding shares.
Sterling, Va.-based MSI, which was set up three-and-a- half years ago, said it expects to book revenue of $35 million in 2010 following record sales and profits in 2009.
The company will continue to operate as MSI Worldwide Mail and will be managed by its founding partners Richard Gerhardt and Christopher Taylor for at least the next five years.
De Post-La Poste said its business unit Belgian Post International will use the new partnership with MSI to further expand its retail operations in the United States and worldwide.
"Having Belgian Post as a strategic partner provides MSI with the global resources necessary to strengthen our position in North America and expand our service offering," said MSI chief executive officer Richard Gerhardt.
"Moreover, the new relationship will allow additional investment in technology and product offerings to meet client demands in the coming decade," Gerhardt said.
