The Convertible Note warrants are considered free-standing instruments and meet the criteria for equity classification because they are indexed to the Company’s own stock and provide a fixed number of shares. Therefore, the fair value of the Convertible Note warrants on May 6, 2021 in the amount of $14,522 was recorded as a debt discount and an addition to “additional paid-in capital” on the consolidated balance sheets.
Interest expense for the three months ended March 31, 2022 was $3,762, of which $1,647 related to contractual interest expense and $2,115 related to amortization of the discount.
Facility
In October 2019, the Company entered into the Facility with a company represented on the Board of Lightning Systems. Upon consummation of the Business Combination, the company holding the Facility was no longer represented on the Board. The Facility provides for both term and working capital loans for borrowings up to $9,000 as of March 31, 2022. However, the Company’s Convertible Note requirements limit the Company’s permitted indebtedness to $5,000. Interest is payable quarterly on borrowings at a fixed annual rate of 15%. Borrowings under the Facility are secured by substantially all the Company’s assets, are subject to borrowing base limitations, and require the Company to meet certain covenants. The Facility borrowings, with a maturity date of October 21, 2024, were $3,000 as of both March 31, 2022 and December 31, 2021. Interest expense was $118 and $630 for the three months ended March 31, 2022 and 2021, respectively.
In connection with entering into this Facility, the Company issued warrants in 2020 and 2019, exercisable into 60,241 and 301,205, respectively, shares of Series C preferred stock at the conversion price of $1.66 per share. At the time of issuance, the Company estimated the fair value of the warrants at $6 and $66, respectively, and recorded a debt discount, which is being recognized over the life of the Facility borrowings, and a warrant liability, which was adjusted to fair value each reporting period, with the changes in fair value reported as a component of “other income, net.” As a result of the Business Combination, the warrants were converted to common stock based on the Exchange Ratio.
Related and Third-party 2020 short-term convertible notes payable
In August and September 2020, the Company borrowed $9,679 in the aggregate under convertible note purchase agreements from third parties ($6,454) and related parties ($3,225). The related parties included officers, a director, and individuals whose companies were represented on the board. These convertible notes bore interest at 8%. Interest was payable monthly, with principal and unpaid interest due June 30, 2021. The notes were convertible into 5,830,723 Series C redeemable convertible preferred shares at the conversion price of $1.66 per share. These notes were subordinate to the Facility and third-party unsecured facility agreement.
The 2020 short-term notes were convertible into shares of Series C redeemable convertible preferred stock upon 1) a change in control (“CIC”) having a value in excess of $200,000; 2) a debt or equity financing with aggregated gross proceeds in excess of $10,000; or 3) at maturity. Should the notes be converted at maturity, the debt holders would receive a beneficial conversion feature allowing the conversion at 75% of the lowest issue price. The Company recorded the beneficial conversion feature at its intrinsic value of $3,071. This was recorded as a debt discount and an addition to “additional paid-in capital”. During the three months ended March 31, 2021, amortization of the debt discount of $981 was recorded to “interest expense”.
As a result of the Business Combination, these convertible notes were converted to Series C redeemable convertible stock which converted into common stock based on the Exchange Ratio with the balance of $9,679 recorded to “additional paid-in capital”. In addition, the accrued interest through the date of the Business Combination close was forgiven.
Third party unsecured facility agreement
In March 2015, the Company borrowed $1,500 under an unsecured facility agreement. As a result of the Business Combination, the amount outstanding was paid in full.
