Nasdaq Communication On May 13, 2019, the Company received written notice from the Staff of the Listing Qualifications Department (the “Staff”) of The Nasdaq Stock Market LLC (“Nasdaq”) indicating that, based upon the Company’s continued non-compliance with the minimum $1.00 bid price requirement for continued listing on The Nasdaq Capital Market, as set forth in Nasdaq Listing Rule 5550(a)(2) (the “Rule”), as of May 8, 2019, and notwithstanding the Company’s compliance with the quantitative criteria necessary to obtain a second 180-day period within which to evidence compliance with the Rule, as set forth in Nasdaq Listing Rule 5810(c)(3)(A), the Staff had determined to delist the Company’s securities from Nasdaq unless the Company timely requests a hearing before the Nasdaq Hearings Panel (the “Panel”). The Company intends to timely request a hearing before the Panel, at which hearing the Company will request an extension within which to evidence compliance with all applicable requirements for continued listing on Nasdaq, including compliance with the Rule. The Company’s request for a hearing will stay any suspension or delisting action by the Staff at least pending the ultimate outcome of the hearing. The Company intends to take definitive steps in an effort to evidence compliance with the Rule; however, there can be no assurance that the Panel will grant the Company’s request for continued listing or that the Company will be able to evidence compliance with the Rule within any extension period that may be granted by the Panel. The Staff’s determination follows the Company’s prior disclosure regarding its receipt of written notice from the Staff dated November 9, 2018, indicating that, because the Company’s bid price had closed below the minimum $1.00 per share threshold for the previous 30-business day period and in accordance with the Nasdaq Listing Rules, the Company had been provided a 180-day grace period, through May 8, 2019, to evidence compliance with the Rule. The Staff’s prior correspondence further indicated that the Company may be eligible for a second 180-day grace period so long as the Company satisfied the continued listing requirement for market value of publicly held shares and all other requirements for initial listing on The Nasdaq Capital Market, with the exception of the bid price requirement, upon the expiration of the first grace period and the Company provided written notice of its intention to cure the deficiency during the second compliance period by effecting a reverse stock split if necessary. The Company satisfied the quantitative requirements to obtain a second 180-day grace period and submitted the requisite notice to the Staff; however, the Staff determined, based on its exercise of discretion, not to grant the Company a second 180-day grace period.
