Financing transaction Private Investment On November 8, 2023, the Company entered into Subscription Agreements (the “Subscription Agreements”) with entities affiliated with Sylebra Capital Limited (“Sylebra”) and Adage Capital Management, providing for the purchase of an aggregate of 36,802,299 shares of the Company’s common stock, $0.0001 par value per share (the “PIPE Shares”), at a price of $0.58 per PIPE Share for an aggregate purchase price of approximately $21.4 million (the “Private Placement”). The PIPE Shares are recorded as outstanding common stock. Standby Equity Purchase Agreement On November 8, 2023, the Company also entered into a Standby Equity Purchase Agreement (the “Facility Agreement”) with entities affiliated with Sylebra, pursuant to which the Company will have the right, but not the obligation to sell to Sylebra up to $125 million of its shares of Preferred Stock, subject to satisfaction of certain conditions, by November 8, 2026. Each sale the Company requests under the Facility Agreement (each, an “Advance” and collectively, the “Advances”) may be for a number of shares of preferred stock with an aggregate value of at least $25.0 million but not more than $50.0 million (except with Sylebra’s consent). When and if issued, the preferred stock will be issued at a price per share of $10,000. Holders of the preferred stock will be entitled to a quarterly dividend at the rate of 7.0% per annum payable in cash or in kind at the option of the Company. The preferred stock will have an initial liquidation preference of $12,000 per share, plus accrued dividends. The preferred stock will have no voting rights as a class or series except in such instances as required by Delaware law or certain matters enumerated in the facility agreement related to the protection of the preferred stock. The preferred stock will be convertible at the option of the holders into the number of shares of Common Stock equal to $10,000 divided by the then-applicable conversion price. At any time after the two year anniversary of any issuance of any series of preferred stock, the Company will have the option to convert all (but not less than all) of any series of then-outstanding preferred stock by paying a make-whole payment, in either stock or cash, equal to three years of dividends, provided that the closing price of the Common Stock exceeds 250% of the then-applicable conversion price for at least 20 out of 30 consecutive trading days prior to the date of conversion. To the extent, if any, a conversion would result any the holder thereof becoming the beneficial owner of more than 19.9% of the Company’s outstanding Common Stock, the Company will issue the Investor Pre-Funded Warrant in the form attached to the Facility Agreement. The preferred stock will be subject to customary pre-emptive rights. The Company’s right to request Advances is conditioned upon the Company achieving a minimum of one new passenger auto-original equipment manufacturer (“OEM”) or commercial OEM program award with at least a 50,000 unit volume, the trading price of the Common Stock being below $3.00 at the time of the Advance request and other customary conditions. Prior to any Advance, the Company will assess its capital needs and other factors, including the impact of an Advance on the Company’s outstanding executive pledge arrangements. The Preferred Stock issued in connection with the facility agreement ranks senior to common stock upon the Company’s liquidation, dissolution or winding up. The Preferred Stock is entitled to priority cumulative dividends which shall accrue daily from and after the original issue date of such share and shall compound on a quarterly basis on each dividend payment date. The accrued dividends shall in all cases be payable upon liquidation. The Company shall pay dividends on each share of Preferred Stock in cash or in kind through issuance of shares of common stock with an aggregate value equal to the amount of the dividend to have been paid divided by the dividend conversion price. The board of directors of the Company may at its sole discretion elect to pay the dividends in cash in lieu of shares of common stock. The Convertible Redeemable Preferred Stock have no voting rights unless they are converted into shares of common stock. Holders may, at their option, elect to convert some or all Preferred Stock held by such holder, at any time and from time to time prior to a change of control, into a number of shares of common stock per share of the Preferred Stock equal to (x) the quotient of the issuance price divided by the conversion price in effect at the time of conversion. At any time on or after the two-year anniversary of the issuance date, the Company shall have the right to redeem the Preferred Stock of any holder outstanding at such time at the issuance price plus three (3) years of dividend payment (“Redemption price”); provided, that (a) the closing price of a share of common stock exceeds 250% of the then-applicable conversion price per share for at least 20 out of 30 consecutive trading days prior to the redemption date and (b) a shelf registration statement that is required to be effective pursuant to the registration rights agreement on such date shall be effective on such date with respect to the applicable holder. The redemption price shall be payable in cash or in shares of common stock. Additionally, upon the occurrence of a change of control, the holders of Preferred Stock shall be entitled to receive in full a liquidating purchase in cash and in the amount per share of the Preferred Stock equal to the sum of (i) the liquidation preference plus (ii) accrued dividends with respect to such shares of Preferred Stock. In connection with this financing, the Company also paid the entities affiliated with Sylebra, (a) a facility fee in the amount of $2.5 million, (b) an origination fee in the amount of $0.6 million, (c) an administrative fee in the amount of $0.3 million and (d) reasonable fees and expenses of the investor and its counsel, up to approximately $0.4 million. The issuance costs related to the Facility Agreement were expensed as incurred as it failed to meet the equity classification guidance under ASC 815-40, and were deemed to be a derivative asset. The fair value of the derivative asset was not material as of and for the period ended December 31, 2023. In addition, upon receipt of stockholder approval in December 2023, the Company issued to Sylebra 15,000,000 Series A Warrants to purchase shares of Common Stock at an exercise price of $1.00. As of December 31, 2023, the Company had 15,000,000 Series A Warrants outstanding. The Series A Warrants were issued as consideration for entering into the Facility Agreement as discussed above. Each Series A Warrant entitles the holder to purchase one share of the Company’s common stock at a price of $1.00 per share. Each Series A Warrant is currently exercisable and expires in December 2027. Holders shall not have the right to exercise the Series A Warrants to the extent that after giving effect to such exercise, such person would beneficially own in excess of 19.9% of the Company’s outstanding common stock immediately after giving effect to such exercise. The exercise price and number of shares of common stock issuable upon exercise of the Series A Warrants may be adjusted in certain circumstances including in the event of a stock dividend or split, subsequent rights offerings, pro rata purchases, merger, reorganization, recapitalization, or spin-off. However, the Series A Warrants will not be adjusted for issuances of shares of common stock at a price below their respective exercise prices. The Series A Warrants do not entitle the holders to any voting rights, dividends or other rights as a stockholder of the Company prior to being exercised for common stock. The Company analyzed the Series A Warrants and determined that they are freestanding and do not exhibit any of the characteristics within ASC 480, and as such do not meet the characteristics of a liability under ASC 480. However, Series A Warrants do not meet all requirements for equity classification under ASC 815, and therefore are classified as a liability on the Company’s consolidated balance sheets.
