Cisco has acquired of Acacia Communications Inc., designer and manufacturer high-speed, optical interconnect technologies for webscale companies, service providers and data center operators, following approval by a majority of Acacia’s shareholders. This acquisition is in line with Cisco’s stated commitment to optics as a critical building block.

“We are thrilled to welcome the Acacia team to Cisco,” said Chuck Robbins, Cisco chairman and CEO. “Our Internet for the Future strategy puts Acacia’s high-speed coherent optics technologies front and center as we work to empower webscale companies, service providers and data center operators to meet today’s fast-growing demands for data.”

Cisco has agreed to acquire Acacia for $115.00 per share in cash, or approximately $4.5 billion on a fully diluted basis, net of cash and marketable securities. As a result of the transaction, Acacia is no longer a publicly traded company. Acacia has notified NASDAQ of the completion of the acquisition and has requested that NASDAQ file a notification of delisting with the Securities and Exchange Commission on Acacia’s behalf.
