9. | CREDIT FACILITY, TERM LOANS, 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. The Company is in compliance with the financial covenants contained within the Credit Agreement as of December 31, 2024. The Company’s credit facility consisted of the following as of December 31, 2023 and 2024 (in thousands):
|  | December 31, 2023 |  |  | December 31, 2024 |

Securities Purchase Agreement and Warrants On March 1, 2022, the Company entered into Securities Purchase Agreements (the “Purchase Agreements”) with certain accredited investors identified on the signature pages to the Purchase Agreements (collectively, the “Purchasers”) pursuant to which, among other things, the Company issued and sold to the Purchasers, in a private placement transaction (the “2022 Private Placement”), (i) 536,361 shares of the Company’s Common Stock (the “Shares”), and accompanying warrants to purchase an aggregate of 402,271 shares of common stock, and (ii) prefunded warrants to purchase up to an aggregate of 251,155 shares of common stock (the “Prefunded Warrants”) and accompanying warrants to purchase an aggregate of 188,366 shares of common stock. The accompanying warrants to purchase common stock are referred to herein collectively as the “Common Stock Warrants”, and the Common Stock Warrants and the Prefunded Warrants are referred to herein collectively as the “Warrants”. Under the Purchase Agreements, each Share and accompanying Common Stock Warrant were sold together at a combined price of $34.92, and each Prefunded Warrant and accompanying Common Stock Warrant were sold together at a combined price of $34.92, for gross proceeds of approximately $27.5 million. In connection with the 2022 Private Placement, the Company entered into a registration rights agreement (the “Registration Rights Agreement”) with the Purchasers, pursuant to which the Company agreed to register for resale the Shares, as well as the shares of common stock issuable upon exercise of the Warrants (the “Warrant Shares”). Under the Registration Rights Agreement, the Company agreed to file a registration statement covering the resale by the Purchasers of the Shares and Warrant Shares within 30 days following the agreement date. The Company filed such resale registration statement on March 28, 2022, and it was declared effective by the SEC on April 8, 2022. Upon the issuance of the Prefunded Warrants and stock purchase warrants, the Company evaluated the terms of each Warrant to determine the appropriate accounting and classification pursuant to ASC 480 and ASC 815. Based on the Company’s evaluation and due to certain terms in the warrant agreements, it concluded the Prefunded Warrant and the stock purchase warrants should be classified as liabilities with subsequent remeasurement at each quarter so long as such warrants remain to be classified as liabilities. The Company recorded an initial liability on issuance of $19.0 million from this conclusion. As of December 31, 2024, the Company has $0.1 million as the liability related to the Warrants.
