Rigrodsky & Long, P.A. Announces Investigation Of Cyan, Inc. (NYSE: CYNI) Buyout

Rigrodsky & Long, P.A. announces that it is investigating potential legal claims against the board of directors of Cyan, Inc. (“Cyan” or the “Company”) (NYSE: CYNI) regarding possible breaches of fiduciary duties and other violations of law related to the Company’s entry into an agreement to be acquired by Ciena Corporation (“Ciena”) (NYSE: CIEN), in a transaction valued at approximately $400 million.

Under the terms of the agreement, shareholders of Cyan will receive consideration equal to the value 0.224 shares of Ciena common stock for each share of Cyan common stock owned.  This exchange ratio represents approximately $4.75 per share of Cyan common stock, based on Ciena’s 20-day volume weighted average price as of May 1, 2015.

The investigation concerns whether Cyan’s board of directors failed to adequately shop the Company and obtain the best possible value for Cyan’s shareholders before entering into an agreement with Ciena.
