Convertible Note

In September 2020, the Company entered into a Convertible Note Purchase Agreement (the “2020 Convertible Notes”) with an investor for gross proceeds of $2.0 million with a stated interest rate of 6.0% per annum. An additional $2.0 million in gross proceeds were made available in December 2020 upon achievement of the integration milestone, whereby the Company successfully created software utilizing the investor’s application programming interface. The 2020 Convertible Notes provided a conversion option whereby upon the closing of a Qualified Financing event, in which the aggregate gross proceeds of the issuance of preferred stock totaled at least $10.0 million, the notes would automatically convert into shares of the same class and series of capital stock of the Company issued to other investors in the financing at a conversion price equal to 80% of the price per share paid by the other investors. The conversion option met the definition of an embedded derivative and was required to be bifurcated and accounted for separately from the notes. The proceeds from the 2020 Convertible Notes were allocated between the derivative liability, with a fair value at issuance of $1.0 million, and the notes, with an initial carrying value of $3.0 million, and included in long-term liabilities on the Company’s consolidated balance sheet. The difference between the initial carrying value of the notes and the stated value of the notes represented a discount that was accreted to interest expense over the term of the Convertible Notes using the effective interest method. This derivative liability was derecognized as of December 31, 2021 as the liability was settled pursuant to the closing of the merger.

As of December 31, 2021 and 2020, the accrued interest on the 2020 Convertible Notes was $0 and less than $0.1 million, respectively. Interest expense totaled $0.3 million and less than $0.1 million for the years ended December 31, 2021 and 2020, respectively.

In January and February 2021, the Company entered into a Convertible Note Purchase Agreement (the “2021 Convertible Notes”) with various investors for gross proceeds of $30.0 million with a stated interest rate of 8.0% per annum. The 2021 Convertible Notes provided a conversion option whereby upon the closing of a Qualified Financing event, in which the aggregate gross proceeds

totaled at least $100.0 million, the notes would automatically convert into shares of the same class and series of capital stock of the Company issued to other investors in the financing at a conversion price equal to 80% of the price per share paid by the other investors. The conversion option met the definition of an embedded derivative and was required to be bifurcated and accounted for separately from the notes. The proceeds from the 2021 Convertible Notes were allocated between the derivative liability, with a fair value at issuance of $7.0 million, and the notes, with an initial carrying value of $23.0 million, and included in long-term liabilities on the Company’s consolidated balance sheet. The difference between the initial carrying value of the notes and the stated value of the notes represented a discount that was accreted to interest expense over the term of the Convertible Notes using the effective interest method. This derivative liability was derecognized as of December 31, 2021 as the liability was settled pursuant to the closing of the merger.

In June 2021, the Company modified the 2021 Convertible Notes to grant the holders an additional 1,000,000 shares of NHIC common stock as further consideration upon the automatic conversion of the notes upon closing of the Merger. This modification of the notes resulted in an extinguishment and the Company recognized a loss on extinguishment of the 2021 Convertible Notes of $11.8 million. The $26.7 million carrying value of the notes at June 21, 2021 was derecognized and replacement notes with an initial carrying value of $29.6 million were recorded. Additionally, in the extinguishment accounting, a derivative liability of $19.2 million was recognized, which represents the value of the 1,000,000 NHIC shares as well as a bifurcated embedded derivative for the conversion option.

Upon the closing of the Merger, the Convertible Notes automatically converted into 4,408,672 shares of the Company’s common stock and the holders of the 2021 Convertible Notes also received the right to receive 1,000,000 shares of the Company’s common stock, as noted above. Upon the conversion of the Convertible Notes, the carrying value of the debt of $32.8 million, and the related derivative liability of $19.7 million and accrued interest of $0.2 million were derecognized resulting in a loss on extinguishment of debt of $0.9 million recorded in other income (expense).

As of December 31, 2021, the accrued interest on the 2021 Convertible Notes was $0. Interest expense totaled $4.9 million for the year ended December 31, 2021.
