Sycamore Networks, Inc. (NASDAQ: SCMR) (the “Company”) announced today that it has filed a certificate of dissolution with the Secretary of State of the State of Delaware (the “Certificate of Dissolution”), as contemplated by the Plan of Complete Liquidation and Dissolution previously approved by the Company’s Board of Directors and stockholders. The Certificate of Dissolution, which became effective at 5:00 p.m. Eastern Time on March 7, 2013, provides for the dissolution of the Company under Delaware’s General Corporation Law. In connection with the filing of the Certificate of Dissolution, effective as of 5:00 p.m. Eastern Time on March 7, 2013, the Company closed its stock transfer books and discontinued recording transfers of its common stock, $0.001 par value per share (the “Common Stock”). The Common Stock, and stock certificates evidencing the shares of Common Stock, are no longer assignable or transferable on the Company’s books, other than transfers by will, intestate succession or operation of law. On March 4, 2013, the Company submitted a request to The NASDAQ Stock Market (“NASDAQ”) to (1) suspend trading of the Common Stock on The NASDAQ Global Select Market effective as of the close of trading on March 7, 2013 and (2) suspend the effectiveness of the Company’s NASDAQ trading symbol effective as of the close of trading on March 7, 2013. The Company also notified NASDAQ of its intention to file a Form 25 with the Securities and Exchange Commission on or about March 15, 2013 to withdraw the registration of the Common Stock under Section 12(b) of the Securities Exchange Act of 1934, as amended, and requested that NASDAQ take the actions necessary to terminate the Company’s NASDAQ listing effective prior to the opening of trading on March 25, 2013. Upon suspension of trading of the Common Stock on The NASDAQ Global Select Market, shares of Common Stock held in street name with brokers may be traded in the over-the-counter market on an electronic bulletin board established for unlisted securities such as the OTC Bulletin Board or the Pink Sheets. Such trading may reduce the market liquidity of the Common Stock and, as a result, investors may find it more difficult to dispose of, or obtain accurate quotations for the price of, the Common Stock, if they are able to trade the Common Stock at all.
