Item 3.01

Regulation FD Disclosure.

On September 3, 2021, the Company received a letter (the “Notice”) from the Listing Qualifications staff of The Nasdaq Stock Market LLC (“Nasdaq”) indicating that, based upon the closing bid price of the Company’s common stock for the last 30 consecutive business days, the Company no longer meets the requirement to maintain a minimum bid price of $1 per share, as set forth in Nasdaq Listing Rule 5450(a)(1) (the “Minimum Bid Price Requirement”).

In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company has been provided a period of 180 calendar days, or until March 2, 2022, in which to regain compliance. In order to regain compliance with the Minimum Bid Price Requirement, the closing bid price of the Company’s common stock must be at least $1 per share for a minimum of ten consecutive business days during this 180-day period. In the event that the Company does not regain compliance within this 180-day period, the Company may be eligible to seek an additional compliance period of 180 calendar days if it meets the continued listing requirement for market value of publicly held shares and all other initial listing standards for the Nasdaq Global Market, with the exception of the Minimum Bid Price Requirement, and provides written notice to Nasdaq of its intent to cure the deficiency during this second compliance period, by effecting a reverse stock split, if necessary. However, if it appears to the Nasdaq Staff that the Company will not be able to cure the deficiency, or if the Company is otherwise not eligible, Nasdaq will provide notice to the Company that its common stock will be subject to delisting.

The Notice does not result in the immediate delisting of the Company’s common stock from the Nasdaq Global Market. The Company intends to monitor the closing bid price of the Company’s common stock to allow a reasonable period for the price to rebound from its recent decline but will continue to consider its available options to regain compliance. There can be no assurance that the Company will be able to regain compliance with the minimum bid price requirement or maintain compliance with the other listing requirements.
