Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On June 13, 2017, Capstone Turbine Corporation, a Delaware corporation (the “Company”), received notice that the Listing Qualifications Department of the Nasdaq Stock Market (“Nasdaq”) has granted the Company an additional 180 days to regain compliance with Nasdaq’s $1.00 per share minimum bid price requirement under Nasdaq Marketplace Listing Rule 5810(c)(3)(A), which will end on December 11, 2017. Previously, on December 12, 2016, Nasdaq notified the Company that it did not meet the minimum bid price requirement required for continued listing on The Nasdaq Capital Market, and the Company was given until June 12, 2017 to achieve compliance.

The Company may achieve compliance during this additional 180-day period if the closing bid price of the Company’s common stock is at least $1.00 per share for a minimum of 10 consecutive business days by December 11, 2017. If the Company fails to regain compliance on or prior to December 11, 2017, the Company’s stock will be subject to delisting by Nasdaq. The Company has provided written notice of its intention to cure the minimum bid price deficiency during the second grace period by effecting a reverse stock split if necessary. The Company intends to request stockholder approval of a reverse stock split at the Company’s annual meeting of stockholders, to be held on August 31, 2017.
