The Company’s Series A Preferred Stock does not pay dividends and is convertible (effective June 6, 2019) into shares of the Company’s common stock at a 1:1 ratio (subject to customary adjustments). The Company has the right to elect to redeem all or a portion of the Series A Preferred Stock at its election after December 6, 2022 for cash at a redemption price equal to the amount of the principal investment plus an additional cumulative amount that will accrue at an annual rate of 7.0% thereon. In addition, if the volume weighted average price of shares of the Company’s common stock equals or exceeds $13.00 for 30 consecutive days, then the Company will have the right to require the holder of the Series A Preferred Stock to convert its Series A Preferred Stock into Company common stock, at a ratio of 1:1 (subject to customary adjustments).

Conditionally redeemable preferred shares (including preferred shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. The preferred stock contains a redemption feature contingent upon a change in control which is not solely within the control of the Company, and as such, the preferred stock is presented outside of permanent equity.
