The lawsuit alleges that the Registration Statement issued in connection with the Offering contained false and/or misleading statements and/or failed to disclose material trends, events and uncertainties known to management, which were reasonably expected to materially impact Rubicon Technology’s income from continuing operations, including: (1) the reversal of its trend of shrinking losses; (2) higher-than-expected development costs; and (3) inventory write-offs due to Rubicon Technology’s inability to sell certain of its wafers during the first quarter of 2014 at prices above their manufacturing cost, which led to an impairment under applicable accounting rules and regulations. When the true details entered the market, the lawsuit claims that investors suffered damages.

A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than June 29, 2015.
