Long-term debt and other borrowings

Loan and Security Agreement (“LSA”)

In June 2018, the Company signed a Loan and Security Agreement (“LSA”) with Bridge Bank (“Bank”), a division of Western Alliance Bank. The purpose of the LSA was to provide long-term financing to the Company through term loans available for borrowing in three tranches up to a maximum of $3.0 million through December 2019 upon the attainment of certain milestones as delineated in the LSA. The first tranche of $0.3 million was borrowed in 2018. The Company was obligated to make interest-only payments until the amortization date of June 28, 2019 and after that date to make principal and interest payments. Interest on outstanding borrowings under the LSA is charged at a rate of 6% per annum. This loan was scheduled to originally mature in May 2022, at which time all outstanding principal and accrued and unpaid interest was due and payable. This loan is secured by substantially all tangible assets of the Company; intellectual property is excluded from the secured collateral but is subject to a negative pledge in favor of the Bank.

In March 2019, the Company entered into a first amendment to the LSA that increased total borrowings to $3.0 million and added a financial liquidity covenant. The amendment was accounted for as a debt modification and no gain or loss was recognized in the Company’s financial statements.

In May 2020, the Company entered into a second amendment to the LSA that increased total borrowings to $5.0 million. The amortization date was extended to May 1, 2021 except, if a certain revenue and new contract bookings milestone is achieved, the amortization date is extended to November 1, 2021. The maturity date of the loan was extended to May 11, 2024. The amendment was accounted for as a debt modification and no gain or loss was recognized in the Company’s financial statements.

In August 2020, the Company entered into a third amendment to the LSA that waived an event of default due to failure to meet a financial covenant. The amendment also expanded the definition of permitted indebtedness to include Payroll Protection Plan (“PPP”) loans, and modified financial and restrictive covenants.

In February 2021, the Company entered into a fourth amendment to the LSA. This amendment gave effect to the Company’s conversion to a corporation and its purchase of Denovium, including permitting certain cash and equity consideration linked to continued employment and service requirements, and adding Denovium as co-borrower to the LSA.

In June 2021, the Company entered into a fifth amendment to the LSA. This amendment modified the term loan’s maturity date to June 16, 2023.

In February 2022, the Company entered into a sixth amendment to the LSA. This amendment modified various definitions and terms within the agreement, with no adjustments to the financial terms.

The Company may prepay all, but not less than all, of the term loans at any time upon 10 days written notice, with a prepayment premium beginning at 1.0% initially and declining to 0% after May 11, 2022. The Company is also required to pay a final payment equal to 3% of the principal amount funded, which is payable upon the earliest to occur of (i) the maturity date, (ii) acceleration and (iii) the prepayment of the loan. As part of the second amendment, the Company paid a one time amendment fee and a pro-rated final payment in connection with the amendment. The final payment represents an additional principal payment and is accounted for as a debt discount that will be accreted through the maturity date of the loan based on the effective interest method.

In connection with entering into the LSA in June 2018, the Company entered into an agreement whereby the Company is required to pay a fee of 3.5% of the aggregate amount of term loans funded by Bank under the LSA within three business days of a sale or other disposition of substantially all of the Company’s assets, a merger or consolidation, a change in control or an initial public offering. Concurrent with the second amendment, the Company and the Bank entered into an amended agreement which extended the term of the fee to May 11, 2030. This fee became payable upon completion of the Company’s IPO on July 26, 2021 and was paid during the year ended December 31, 2021.

In June 2022, the Company paid off the remaining $2.4 million outstanding balance of the LSA.

Convertible Note

In March 2021, the Company entered into a Note Purchase Agreement to issue and sell $125.0 million convertible promissory notes (the “2021 Notes”) to certain investors. The 2021 Notes accrued interest at 6% per annum. Due to certain embedded features within the 2021 Notes, the Company elected to account for these notes, including all of their embedded features, under the fair value option. The Company has elected to recognize interest expense based on the 6% per annum coupon rate of the Notes, which was included in other long-term liabilities on the condensed consolidated balance sheet through the date of the IPO. Based on the terms of the agreement, the 2021 Notes converted at an 18% discount from the offering price to the public in the IPO. Prior to the conversion, the Company recorded a final fair value adjustment of the 2021 Notes using the Company's common stock price at the IPO. Immediately prior to the completion of the IPO, all outstanding principal under the 2021 Notes and the related accrued interest expense were converted into an aggregate of 9,732,593 shares of our common stock based on an initial public offering price of $16.00 per share.

Equipment Financing

In the three months ended June 30, 2022, the Company received $9.4 million of proceeds from equipment financing arrangements with multiple financial institutions. Terms of the agreements require monthly payments over 42-48 month maturities with imputed interest rates ranging 8%-10%. All outstanding principal and accrued and unpaid interest is due and payable at maturity. These loans are secured by certain tangible assets of the Company and include certain financial liquidity covenants. The Company was in compliance with all applicable financial covenants as of June 30, 2022.
