 Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.On April 19, 2016, Rubicon Technology, Inc. (the "Company") received notice from the Listing Qualifications Department of the NASDAQ Stock Market LLC ("NASDAQ") indicating that the Company is not in compliance with the minimum bid price requirement of $1.00 per share, as set forth in NASDAQ Listing Rule 5450(a)(1), because the closing bid price for the Company's stock has been below $1.00 for 30 consecutive business days. The notification has no immediate effect on the listing or trading of the Company's common stock on The NASDAQ Global Market and the common stock will continue to trade under the symbol "RBCN".
 
 In accordance with NASDAQ Listing Rule 5810(c)(3)(A), the Company has a grace period of 180 calendar days, or until October 17, 2016, to regain compliance with the minimum closing bid price requirement for continued listing. In order to regain compliance, the closing bid price of the Company's common stock must be at least $1.00 per share for a minimum of ten consecutive business days. NASDAQ may, in its discretion, require the Company's common stock to maintain a bid price of at least $1.00 per share for a period in excess of ten consecutive business days, but generally no more than 20 consecutive business days, before determining that the Company has demonstrated an ability to maintain long-term compliance. In the event the Company does not regain compliance by October 17, 2016, the Company may be eligible for an additional 180 calendar days grace period if it elects to transfer the listing of its common stock to the NASDAQ Capital Market. To qualify, the Company would be required to (1) satisfy the applicable market value of publicly held shares requirement for continued listing and the other applicable requirements for initial listing on the NASDAQ Capital Market, with the exception of the minimum bid price requirement, and
 (2) provide written notice to NASDAQ of its intention to cure the minimum bid price deficiency during the second grace period, including by effecting a reverse stock split, if necessary. In addition, it must appear to NASDAQ that it is possible for the Company to cure the deficiency. If the Company fails to qualify for the second grace period or fails to regain compliance during the second grace period, the Company's common stock will be subject to delisting by NASDAQ. At that time, the Company may appeal the delisting determination to an independent Hearings Panel authorized by the NASDAQ Board of Directors.
 
 The Company intends to monitor the bid price for its common stock between now and October 17, 2016 and will consider available options to resolve the deficiency and regain compliance with the NASDAQ minimum bid price requirement. However, there is no assurance that the Company will be eligible for an additional grace period or that its common stock will not be delisted.
