Acacia Communications Provides Business Update

MAYNARD, Mass., May 31, 2017 -- Acacia Communications, Inc. (NASDAQ:ACIA), a leading provider of high-speed coherent optical interconnect products, today announced that the Company has identified a quality issue that it currently believes affects a portion of the approximate 1,300 AC400 units and 5,000 CFP units manufactured by one of its three contract manufacturers over an approximate four month period.  The Company believes the root cause of this quality issue has been identified as a circuit board cleaning process that has since been eliminated, and manufacturing at this contract manufacturer has resumed.  The Company does not believe that products currently being shipped are affected by this quality issue.  The Company is actively working with affected customers to remediate this issue.  The Company is also working to estimate the cost of these remediation efforts and assess the impact of this issue on its near-term manufacturing capacity.
