Roy Jacobs & Associates announces that it continues and has expanded its investigation as to whether the Board of Directors of Great Basin Scientific, Inc. (“GBSN” or “the Company”) violated the federal securities laws and/or state fiduciary laws, and if so, what legal action can be taken to protect shareholder interests.

The investigation centers on the Company’s sale on February 25, 2015 of 2,724,000 units (“Units”) in a public offering, which (upon conversion into preferred stock and warrants) resulted in an obligation to issue hundreds of millions of new shares, dramatically reducing the stock price to a penny stock from its 2015 high of $6.10.

If you purchased Units in the February 2015 Offering and have a loss on that investment (and whether or not you still hold GBSN shares and/or Warrants) and wish to discuss potentially joining in an action to protect your rights, or have any questions concerning this notice, please contact Roy Jacobs. Mr. Jacobs will personally speak with you at no cost or obligation.
