On December 6, 2013, Rubicon filed an amended shelf registration statement (the "Form S-3A") with the SEC which included a form of prospectus (the "Prospectus") authorizing the Company and to-be-identified "selling stockholders" to sell up to $100 million worth of shares of Rubicon common stock, at any time, in one or more offerings. Thereafter, on March 19, 2014, Rubicon filed a prospectus supplement (the "Prospectus Supplement") with the SEC offering to register 2.5 million shares of Rubicon common stock (not including an overallotment of 375,000 shares) for sale at $13.00 per share by selling shareholders Cross Atlantic Funds, a group of funds controlled by one of Rubicon's directors. The Offering was sold pursuant to the Form S-3A, the Prospectus and the Prospectus Supplement (jointly referred to herein as the "Registration Statement").

The complaint Robbins Geller filed on behalf of investors charges Rubicon, certain of its officers and directors and the underwriters of the Offering with violations of the Securities Act of 1933 based upon materially false and misleading statements and omissions in the Registration Statement, which was prepared in violation of SEC rules and regulations. Specifically, the Registration Statement negligently failed to disclose material trends, events and uncertainties known to management that were reasonably expected to have a material impact on the Company's income from continuing operations, including the reversal of its trend of shrinking losses, higher-than-expected development costs and inventory write-offs due to Rubicon's inability to sell certain of its wafers during its 2014 first quarter at prices greater than their cost to manufacture, causing such inventory to be impaired under applicable accounting rules and regulations.

On May 1, 2014, the Company issued a press release and hosted a conference call regarding its 2014 first quarter in which the Company reported disappointing financial results and revealed, among other things, that the trend of shrinking gross losses, operating losses, and losses per share from the prior quarters had dramatically reversed in the first quarter of 2014, causing substantial increases in gross losses of $7.5 million, losses from operations of $10.9 million, and losses per share of $0.43.  Thereafter, Rubicon common stock declined by approximately 16%. The stock is currently trading below $3.00 per share, more than 75% below the Offering price.

The plaintiff, represented by Robbins Geller, seeks to recover damages on behalf of all purchasers of Rubicon common stock in the Offering on or about March 19, 2014.
