The Company has been negatively impacted by the ongoing COVID-19 pandemic, has historically experienced recurring losses, has been dependent on raising capital from the sale of securities in order to continue to operate and refinanced its debt at a lower interest rate. During the COVID-19 pandemic, the Company received cash proceeds from the PPP loan, which was forgiven, and the EIDL loan (each as defined in Note 10 below) that was repaid at the time the senior credit facility entered into with MidCap Financial Trust in September 2021 (see Note 10). Additionally, in October 2021, the Company entered into an equity distribution agreement with an investment bank under which the Company may sell up to $11,000 of its common stock in registered “at-the-market” offerings (see Note 16). Management believes that the Company’s cash and cash equivalents, combined with the anticipated revenues from the sale or use of the Company’s products, will be sufficient to satisfy our working capital needs, capital asset purchases, outstanding commitments and other liquidity requirements associated with its existing operations through the next 12 months following the date of the issuance of these unaudited interim condensed consolidated financial statements. However, the negative impact of the ongoing COVID-19 outbreak on the financial markets and supply chain disruptions could interfere with the Company’s ability to access financing and on favorable terms.
