Last month, Cisco and Acacia Communications (ACIA) - Get Report said they had agreed to a new $4.5 billion merger after a disagreement linked to regulatory clearance from China nearly derailed the deal.
Cisco will pay $115 a share for Acacia, the company said, ending months of wrangling over the 2019 deal aimed at giving Cisco a clearer path into spending linked to 5G network rollouts.
The transaction is expected to close during the third quarter, subject to a vote of Acacia holders, Cisco said. The company added that the companies have received all necessary regulatory clearances.
