Arbinet and Primus announced today the pending aquisition of Arbinet by Primus. The all stock transaction deal will allow both companies to provide both companies increased scale, market position and global reach. The announcement is only the beginning of the process. The deal still needs to be approved by regulatory officials and Board of Directors of both companies. In addition, the agreement also contains a 'go-shop' provision that allows Arbinet to solicit alternative proposals from third parties over the next 45 calendar days.
