Nasdaq delisting notification description The Company received a notification from the Nasdaq Stock Market (the "Nasdaq") indicating that the minimum bid price of the Company's common stock has been below $1.00 per share for 30 consecutive business days and as a result, the Company is not in compliance with the minimum bid price requirement for continued listing. The Nasdaq notice has no immediate effect on the listing or trading of the Company's common stock. Under the Nasdaq Listing Rules, the Company has a grace period of 180 calendar days, or until August 31, 2020, in which to regain compliance with the minimum bid price rule. To regain compliance, the closing bid price of the Company's common stock must meet or exceed $1.00 per share for a minimum of ten consecutive business days during this grace period. On April 20, 2020, the Company received a written notice from Nasdaq indicating that, as a result of the tolling of the bid price requirements due to COVID-19, the period within which the Company has to regain compliance was extended from August 31, 2020 to November 13, 2020.
