Loan Agreements

On March 29, 2019, the Company entered into a Credit, Security and Guaranty Agreement (Term Loan) (the “Prior Term Loan Credit Agreement”) with MidCap Financial Trust (“MidCap”) to borrow up to $70 million in three tranches (collectively “Prior Term Loan”), with a maturity date of March 1, 2024. The first advance of $40.0 million (“Tranche 1”) was drawn by the Company on March 29, 2019, with the proceeds used in part to repay in full the outstanding term loans and fees under a prior loan agreement. The second advance of $15.0 million (“Tranche 2”) was drawn by the Company on March 29, 2021. The third advance of $15.0 million (“Tranche 3”) expired on December 31, 2021. The borrowings under the Prior Term Loan bear interest at the sum of a fixed percentage spread and the greater of (i) 1.80% or (ii) one month SOFR plus 0.1%.

On March 31, 2023, the Company entered into an Amended and Restated Credit, Security and Guaranty Agreement (Term Loan) (the “Term Loan Credit Agreement”) which amended and restated the Prior Term Loan Credit Agreement. The Term Loan Credit Agreement provides a secured term loan facility in an aggregate principal amount of up to $75.0 million. The Company borrowed the first advance of $40.0 million (“Tranche 1”) and the second advance of $15.0 million (“Tranche 2”) on the closing date to refinance the term loans under the Prior Term Loan Credit Agreement. Under the terms of the Term Loan Credit Agreement, (i) the third advance of $10.0 million (“Tranche 3”) was available to the Company through July 1, 2024, and (ii) the fourth advance of $10.0 million (“Tranche 4”), was available to the Company through July 1, 2025, subject to the Company’s satisfaction of certain other conditions described in the Term Loan Credit Agreement.

Tranche 1, Tranche 2, Tranche 3, and Tranche 4, each bear interest at a floating rate equal to the sum of the Term SOFR rate (subject to a floor of 1.00%) plus 6.50%. Interest on each term loan advance is due and payable monthly in arrears. Interest only payments are due for the first 36 months, and the remaining payments are due over the remaining 24 months. The interest only payment period can be extended for 12 months upon achievement of a specified trailing 12 month net revenue target. The interest rate at December 31, 2025 is approximately 10.7%.

On September 1, 2023, the Company entered into Amendment 1 of the Term Loan Credit Agreement. At the close of this amendment, the Company borrowed $5.0 million available under Tranche 3. On January 5, 2024 the Company entered into Amendment 2 of the Term Loan Credit Agreement which was effective December 31, 2023, which removed the minimum revenue condition applicable to the remaining $5.0 million available in Tranche 3, which became eligible to be drawn at any time prior to July 1, 2024. The Company borrowed the remaining $5.0 million available in Tranche 3 on March 27, 2024.

Prepayments of the term loans under the Term Loan Credit Agreement, in whole or in part, will be subject to early termination fees which decline each year through the term of the Term Loan Credit Agreement. The Company also must pay an annual administrative fee equal to a fractional percentage of the amount outstanding pursuant to the Term Loan Credit Agreement, and upon the final payment must also pay an exit fee of a percentage of the amount borrowed pursuant to the Term Loan Credit Agreement (the “Exit Fee”). The Company is required to pay a pro rata portion of the Exit Fee in connection with any prepayment. The Company uses the effective interest method to recognize the Exit Fee over the term of the debt.

The Company also maintained a Credit, Security and Guaranty Agreement (Revolving Loan) (the “Prior Revolving Loan Credit Agreement”) with MidCap. The borrowing limit under the Prior Revolving Loan Credit Agreement was $15.0 million which had a maturity date of March 1, 2024. The amount borrowed under the Prior Revolving Loan Credit Agreement could be increased, upon request by the Company, by up to an additional $5.0 million, subject to agent and lender approval and the satisfaction of certain conditions.

On March 31, 2023, the Company entered into Amended and Restated Credit, Security and Guaranty Agreement (Revolving Loan) (the “Revolving Loan Credit Agreement”) which amended and restated the Prior Revolving Loan Credit Agreement and has a maturity date of March 1, 2028. The Revolving Loan Credit Agreement provides a secured revolving credit facility in an initial aggregate principal amount of up to $20.0 million. The Company may request an increase in the total commitments under the Revolving Loan Credit Agreement by up to an additional $15.0 million, subject to agent and lender approval and the satisfaction of certain conditions.

Loans under the Revolving Loan Credit Agreement accrue interest at a floating rate equal to the Term SOFR rate (subject to a floor of 1.00%) plus 3.75%. Accrued interest on the revolving loans will be paid monthly and revolving loans may be borrowed, repaid and re-borrowed until March 1, 2028, when all outstanding amounts must be repaid. Termination or permanent reductions of the revolving loan commitment under the Revolving Loan Credit Agreement will be subject to termination fees which decline each year until the fourth anniversary of the Revolving Loan Credit Agreement, at which time there is no early termination fee.

In connection with the Revolving Loan Credit Agreement, the Company is required to pay customary fees, including an origination fee equal to a fractional percentage of the original commitment amount at closing (and an equivalent origination fee with respect to any increased commitments at the time of the applicable increase), a monthly unused line fee based upon the average daily unused allowable borrowing base of the revolving credit facility and a monthly collateral management fee based upon the average daily used portion of the revolving credit facility. The Company is also required to maintain a minimum drawn balance under the revolving line or pay interest on the minimum drawn balance.

As of December 31, 2025 and December 31, 2024, the Company had borrowed $19.0 million and $19.3 million, respectively, under the Revolving Loan Credit Agreement, which is included in “Debt – current” in the Company’s consolidated balance sheets.

The Term Loan Credit Agreement and Revolving Loan Credit Agreement contain certain financial and non-financial covenants, with which the Company was in compliance at December 31, 2025. Additionally, the Company’s obligations under both agreements are secured by a security interest in substantially all of the Company’s assets, with some exclusions.
