Coherent, Inc. Receives Anticipated Letter from NASDAQ

Coherent, Inc.

The Company will initiate the appeal process by requesting a hearing before the Nasdaq Listing Qualifications Panel in response to the letter. Pending a decision by the panel, Coherent shares will remain listed on the Nasdaq Stock Market.
