2027 Notes

On November 16, 2022, the Company entered into a purchase agreement (the “Purchase Agreement” with Goldman Sachs & Co. LLC, as representative of the initial purchasers (collectively the “Initial Purchasers”), pursuant to which the Company agreed to sell $140,000 aggregate principal amount of 4.50% Convertible Senior Notes due 2027 (the “Initial Notes”). The Company also agreed to grant an option, exercisable within the 30-day period immediately following the date of the Purchase Agreement (the “Option”) to the Initial Purchasers to purchase all or part of an additional $20,000 aggregate principal amount of 4.50% Convertible Senior Notes due 2027 (the “Additional Notes” and, together with the Initial Notes, the “2027 Notes”). On November 17, 2022, the Initial Purchasers exercised the Option in full, bringing the total aggregate principal amount for the 2027 Notes to $160,000. The sale of the 2027 Notes closed on November 21, 2022. The 2027 Notes were issued pursuant to an Indenture dated November 21, 2022 (the “Indenture”), between the Company and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”). Interest on the 2027 Notes will be payable semiannually in arrears on May 15 and November 15 of each year, beginning on May 15, 2023. The 2027 Notes will mature on November 15, 2027, unless earlier repurchased, redeemed or converted.

The 2027 Notes will be convertible into cash, shares of the Company’s Class A common stock, par value $0.0001 per share (“common stock”), or a combination of cash and shares of common stock, at the Company’s election, at an initial conversion rate of 115.5869 shares of common stock per $1,000 principal amount of the 2027 Notes, which is equivalent to an initial conversion price of approximately $8.65 per share of common stock. The initial conversion price of the Notes represents a premium of approximately 30% over the $6.655 per share last reported sale price of the common stock on The Nasdaq Capital Market on November 16, 2022. The conversion rate will be subject to adjustment upon the occurrence of certain specified events, but will not be adjusted for any accrued and unpaid interest, except under the limited circumstances described in the Indenture. In addition, upon the occurrence of a “Make-Whole Fundamental Change” (as defined in Section 1.01 of the Indenture) prior to the maturity date, or if the Company delivers a notice of redemption, the Company will, in certain circumstances, increase the conversion rate by a number of additional shares of common stock (not to exceed 150.2629 shares of common stock per $1,000 principal amount of the Notes, subject to adjustment in the same manner as the conversion rate) for Notes that are converted in connection with such Make-Whole Fundamental Change or for notes called (or deemed called) for redemption that are converted in connection with such notice of redemption.

The Notes are convertible at the option of the holders (in whole or in part) at any time prior to the close of business on the business day immediately preceding August 15, 2027 only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on December 31, 2022 (and only during such calendar quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five business day period after any five consecutive trading day period (the “measurement period”) in which the “Trading Price” (as defined in Section 1.01 of the Indenture) per $1,000 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of common stock and the conversion rate on each such trading day; (3) if the Company calls such Notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date, but only with respect to the Notes called (or deemed called) for redemption; or (4) upon the occurrence of certain corporate events as specified in the Indenture. On or after August 15, 2027 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or a portion of their Notes, in multiples of $1,000 principal amount, at any time, regardless of the foregoing circumstances. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of common stock or a combination of cash and shares of common stock, at the Company’s election, in amounts determined in the manner set forth in the Indenture.

The Company may not redeem the 2027 Notes prior to November 20, 2025. indie may redeem for cash all or any portion of the 2027 Notes, at indie’s option, on or after November 20, 2025 if the last reported price of indie’s Class A common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which indie provides notice of redemption, at a redemption price equal to 100% of the principal amount of the 2027 Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.

Upon the occurrence of a “Fundamental Change” (as defined in Section 1.01 of the Indenture), subject to certain conditions and certain limited exceptions, holders may require the Company to repurchase for cash all or any portion of their Notes in principal amounts of $1,000 or an integral multiple thereof at a fundamental change repurchase price in cash equal to 100% of the

principal amount of the Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

The Notes are senior unsecured obligations of the Company and rank: (i) senior in right of payment to any indebtedness of the Company that is expressly subordinated in right of payment to the Notes; (ii) equal in right of payment to any unsecured indebtedness of the Company that is not so subordinated; (iii) effectively junior in right of payment to any senior, secured indebtedness of the Company to the extent of the value of the assets securing such indebtedness; and (iv) structurally junior to all indebtedness and other liabilities (including trade payables) of the Company’s subsidiaries.

The 2027 Notes have been recorded as long-term debt in its entirety pursuant to ASU 2020-06. The carrying value of the 2027 Notes is presented net of $5,374 of discount and issuance costs, which are amortized to interest expense over the respective terms of these borrowings. As of December 31, 2022, the total carrying value of the 2027 Notes, net of unamortized discount, was $154,742. The amortization of the debt discount and cost of issuance resulted in non-cash interest expense of $116 for the year ended December 31, 2022, and is also included in Interest Expense in the Company’s consolidated statements of operations.

In connection with the offering of the Convertible Senior Notes, the Company entered into privately negotiated transactions through one of the initial purchasers or its affiliate to repurchase 1,112,524 shares of common stock, at an average cost of $6.65 per share, for approximately $7,404.

Embry Convertible Subordinated Notes Payable

On December 4, 2012, the Company entered into two convertible note and exchange agreements with an investor, pursuant to which the entire outstanding principal of $3,500 and corresponding accrued interest of $107 held under existing loan agreements were exchanged for two convertible subordinated notes with aggregate principal amounts of $2,604 and $1,003. The convertible subordinated notes bore interest of 0.93% per annum, which was compounded annually. The aggregate principal and all accrued and unpaid interest were due in full on December 4, 2017. On December 3, 2017, the Company entered into a 12-month extension of these two convertible note and exchange agreements.

On December 3, 2018, the Company entered into a 36-month extension of these two convertible notes and exchange agreements. The interest rate on the 36-month extension was amended to 3.07% per annum. The Company recorded a discount on this convertible debt extension and a corresponding increase in additional paid-in capital related to the enhanced value of the embedded conversion options. The Company is amortizing the discount to interest expense over the 36-month extension period.

The amendments to extend the maturity date were treated as modifications of the debt.

The convertible subordinated notes with aggregate principal of $2,604 and $1,003 were converted into an aggregate 185,000 Class A units and 100,000 Class C units, respectively, at the investors’ discretion prior to the maturity date or automatically upon a liquidity event, as defined in the loan agreement. The Company determined that the embedded conversion options should not be bifurcated from their host instruments.

In December 2020, Embry assigned the notes to its affiliate, Cézanne Investments Ltd. (“Cézanne”). At December 31, 2020, the total carrying value of such convertible subordinated notes payable, net of unamortized discount, was $3,496. Total accrued interest as of December 31, 2020 was $458, and is included in Accrued expenses and other current liabilities on the Company’s consolidated balance sheets. On June 10, 2021, Cézanne exercised its right to convert at the closing of the Transaction and the Embry convertible notes were converted to equity at their carrying value of $4,119, inclusive of $3,607 principal balance and accrued interest of $512.

PacWest Revolving Line of Credit

The Company entered into a loan and security agreement with Pacific Western Bank (“PacWest”) in January 2015, that provided a term loan of up to $10,000 with a maturity date of September 2020. The term loan bore interest equal to the greater of one percent above the prime rate in effect, or 4.5% on outstanding borrowings. In addition, the loan and security agreement provided for a revolving line of credit. The revolving line of credit bore interest equal to the greater of seventy-five basis points above the prime rate in effect, or 4.25%, on outstanding borrowings. The terms of the loan and security agreement have been amended from time to time and was most recently amended on November 5, 2021 as described below. The amendments have,

among other things, extended the maturity date of the loan and adjusted the financial covenants’ borrowing limits. During 2020, the outstanding balance on the term loan was transferred to the revolving line of credit.

On November 5, 2021, the Company entered into an amendment to the PacWest loan agreement (the “Amended Line of Credit”) that (i) increased the maximum borrowing capacity under the revolving line of credit to $20,000, (ii) limited the security interests of the bank to the cash collateral set at 102.5% of the drawn amount of the loan, (iii) removed various reporting and restrictive covenants, (iv) extended the maturity date to November 4, 2022 and (iv) reduced the interest rate to 2.1% per annum. In addition, the amendment required the Company to collateralize a cash balance equal to the total outstanding balance in a cash security account with PacWest. Upon execution of the Amended Line of Credit, the Company repaid the outstanding balance of $1,675 under the original line of credit to this new arrangement.

The Company’s borrowings under the Amended Line of Credit were subject to an aggregate borrowing limit of $20,000 as of December 31, 2021. Total borrowings at any given time under the Amended Line of Credit were limited to a percentage of domestic accounts receivables less than 90 days past due and other factors.
