Juniper Networks investor activism

Jana Partners has established a 13,432,722-share position in Juniper Networks, Inc. (NYSE:JNPR) over the last few months. That means Jana has made a more than $300 million bet on Juniper.

Jana Partners is joined by Elliott Management in its activist efforts with Juniper Networks, Inc. (NYSE:JNPR). Elliott is headed by Paul Singer, who also wants Juniper “to cut costs, streamline its product offerings and return money to shareholders”. Elliot has already disclosed a 6.2% stake in the network equipment giant. Both groups of activist investors have said that they hope Juniper’s new CEO (Shaygan Kheradpir) is looking to increase shareholder value in the near term.
