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 a Paycheck Protection Program (“PPP”) loan, which was forgiven, and an Economic Injury Disaster Loan (the “EIDL loan”) that was repaid at the time the Senior Term Facility was entered into with MidCap Financial Trust in September 2021 (Note 9). Additionally, in October 2021, the Company entered into an equity distribution agreement with an investment bank under which the Company may sell up to $11.0 million of its common stock in registered “at-the-market” offerings. Management believes that the Company’s cash and cash equivalents, combined with the anticipated revenues from the sale or use of its products, will be sufficient to satisfy the Company’s working capital needs, capital asset purchases, outstanding commitments and other liquidity requirements associated with its existing operations for at least 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.

During the COVID-19 pandemic, the Company received cash proceeds from a Paycheck Protection Program (“PPP”) loan, which was forgiven, and an Economic Injury Disaster Loan (the “EIDL loan”) that was repaid at the time the Senior Term Facility was entered into with MidCap Financial Trust in September 2021 (Note 9). Additionally, in October 2021, the Company entered into an equity distribution agreement with an investment bank under which the Company may sell up to $11.0 million of its common stock in registered “at-the-market” offerings. Management believes that the Company’s cash and cash equivalents, combined with the anticipated revenues from the sale or use of its products, will be sufficient to satisfy the Company’s working capital needs, capital asset purchases, outstanding commitments and other liquidity requirements associated with its existing operations for at least the next 12 months following the date of the issuance of these unaudited interim condensed consolidated financial statements.
