8. CREDIT FACILITY AND WARRANTS

MidCap Credit Facility

On December 22, 2021, the Company entered into a Credit and Security Agreement (the “Credit Agreement”) together with certain of its subsidiaries party thereto as borrowers, the entities party thereto as lenders, and Midcap Funding IV Trust, as administrative agent, pursuant to which, among other things, (i) the Lenders agreed to provide a three year revolving credit facility in a principal amount of up to $40.0 million subject to a borrowing base consisting of, among other things, inventory and sales receivables (subject to certain reserves), and (ii) the Company agreed to issue to MidCap Funding XXVII Trust a warrant (the “Midcap Warrant”) to purchase up to an aggregate of 16,667 shares of common stock of the Company, par value $0.0001 per share, in exchange for the Lenders extending loans and other extensions of credit to the Company under the Credit Agreement.

The obligations under the Credit Agreement are a senior secured obligation of the Company and rank senior to all indebtedness of the Company. Borrowings under the Credit Agreement bear interest at a rate of Term Secured Overnight Financing Rate ("Term SOFR"), which is defined as SOFR plus 0.10%, plus 5.50%. The Company will also be required to pay a commitment fee of 0.50% in respect of the undrawn portion of the commitments, which is generally based on average daily usage of the facility during the immediately preceding fiscal quarter. The Credit Agreement does not require any amortization payments.

The Credit Agreement minimum liquidity covenant, which includes the Company’s unrestricted U.S. cash plus the revolving loan availability, requires that Midcap shall not permit the credit party liquidity at any time to be less than (a) during the period commencing on February 1st through and including May 31st of each calendar year, $12.5 million and (b) at all other times, $15.0 million. The Credit Agreement includes events of default that are customary for these types of credit facilities, including the occurrence of a change of control.

The Midcap Warrant has an exercise price of $56.40 per share, subject to adjustment for stock splits, reverse stock splits, stock dividends and similar transactions, is immediately exercisable, has a term of ten years from the date of issuance and is exercisable on a cash or cashless basis.

On February 23, 2024, the Company amended its asset backed credit facility with MidCap Financial Trust. The Credit Facility term was extended to December 2026 and gives the Company access to $17 million in current commitments which can be increased, subject to certain conditions, to $30.0 million. The Credit Facility extension reduced the minimum liquidity financial covenant from a peak of $15.0 million to $6.8 million of U.S. cash on hand and/or availability in the Credit Facility. The extension fee was less than $0.1 million.

On March 25, 2025 (the “Third Amendment Effective Date”) the Company entered into Amendment No. 3 (the “3rd Amendment”) to the Credit Agreement. Material changes contained in the 3rd Amendment include, among other things, adding repurchase of the Company’s common stock of up to $1.5 million per year, consisting of up to $1.5 million in repurchases allowed during the period from March 25, 2025 through December 22, 2025, and up to an additional $1.5 million allowed during the period from December 23, 2025 through the maturity date, subject to certain liquidity and compliance conditions.

On August 29, 2025 (the “Fourth Amendment Effective Date”) the Company entered into Amendment No. 4 to the Credit Agreement. Material changes contained in Amendment No. 4 include a reduction to the Minimum Credit Party Liquidity covenant to $5.0 million, upon the Company’s delivery of a Liquidity Certificate evidencing liquidity of at least $6.8 million, the Minimum Liquidity Covenant Reduction Period will terminate and the covenant will increase to $6.8 million thereafter, and an Availability Reserve of $2.8 million during the Minimum Liquidity Covenant Reduction Period and $1.0 million thereafter.

On March 13, 2026 (the "Fifth Amendment Effective Date"), the Company and its subsidiaries entered into Amendment No. 5 to its Credit and Security Agreement with MidCap Funding IV Trust. Under the terms of the amendment, the Company’s minimum liquidity covenant was reduced from $5.0 million to $3.5 million during the Minimum Liquidity Covenant Reduction Period. This reduction period commenced on the Fifth Amendment Effective Date and is subject to extension at the Company's option on a weekly basis through May 9, 2026, provided it remains in compliance with certain fee payment obligations.

The Company is in compliance with the financial covenants contained within the Credit Agreement as of March 31, 2026. As of May 2, 2025, the Company had temporarily suspended its share repurchase program.

Securities Purchase Agreement and Warrants

In March 2022, the Company raised approximately $27.5 million through a private placement involving common stock and accompanying stock purchase warrants. The 590,637 common stock warrants issued in the transaction were classified as liabilities with subsequent remeasurement each quarter. As of March 31, 2026, these warrants remain outstanding and have no associated liability recorded on the Company’s Condensed Consolidated Balance Sheet due to the decline in the Company’s share price.
