CONVERTIBLE SENIOR NOTES |
CONVERTIBLE SENIOR NOTES | (8) CONVERTIBLE SENIOR NOTES In May 2023, the Company issued $52.5 million aggregate principal amount of 5.00% Convertible Senior Notes due May 15, 2026 (the “2023 Convertible Senior Notes”). In May 2023, the Company issued an additional $7.5 million aggregate principal amount of the 2023 Convertible Senior Notes upon the exercise by the initial purchasers of their over-allotment option. As of December 31, 2024 and March 31, 2025, unamortized issuance costs of $1.4 million and $1.2 million, respectively, were included on the Company’s condensed consolidated Balance Sheets. Interest on the 2023 Convertible Senior Notes is payable semiannually in arrears, beginning November 15, 2023. The 2023 Convertible Senior Notes will mature on May 15, 2026, unless earlier converted or repurchased, and are redeemable at the option of the Company on or after May 20, 2025. The 2023 Convertible Senior Notes are direct, unsecured, and unsubordinated obligations of the Company, ranking equally with all of the Company’s other unsecured and unsubordinated indebtedness from time to time outstanding, and are effectively subordinated to all secured indebtedness of the Company. Holders could have converted their 2023 Convertible Senior Notes at their option prior to the close of business on the business day preceding March 31, 2025, but only under the following circumstances: during any calendar quarter (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least twenty trading days (whether or not consecutive) during the period of thirty 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 as determined by the Company; during the five business day period after any ten consecutive trading day period (the “Measurement Period”) in which the trading price per $1,000 principal amount of 2023 Convertible Senior Notes for each trading day of the Measurement Period was less than 98% of the product of the last reported sale price of the common stock and the conversion rate on each such trading day; or upon the occurrence of certain corporate events specified in the indenture governing the 2023 Convertible Senior Notes. On or after February 15, 2026, a holder may convert all or any portion of its 2023 Convertible Senior Notes at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date regardless of the foregoing conditions. The Company will settle conversions of the 2023 Convertible Senior Notes by paying cash up to the aggregate principal amount of the 2023 Convertible Senior Notes to be converted and paying or delivering, 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 respect of the remainder, if any, of the Company's conversion obligation in excess of the aggregate principal amount of the 2023 Convertible Senior Notes being converted. The 2023 Convertible Senior Notes are initially convertible at a rate of 92.8031 shares of common stock per $1,000 principal amount converted, which is approximately equal to $10.78 per share of common stock. The conversion rate will be subject to adjustment upon the occurrence of certain specified events but will not be adjusted for accrued and unpaid interest. In addition, upon the occurrence of a make-whole fundamental change, which includes certain change in control transactions, the approval by Zynex’s stockholders of any plan or proposal for the liquidation or dissolution of Zynex and certain de-listing events with respect to Zynex’s common stock, the Company will, in certain circumstances, increase the conversion rate by a number of additional shares of common stock for conversions in connection with the make-whole fundamental change. Upon the occurrence of a fundamental change, holders of the 2023 Convertible Senior Notes may require the Company to purchase all or a portion of their 2023 Convertible Senior Notes, in principal amounts equal to $1,000 or an integral multiple thereof, for cash at a price equal to 100% of the principal amount of the 2023 Convertible Senior Notes to be purchased plus any accrued and unpaid interest. The following table summarizes the minimum interest payments over the remainder of 2025 and next fiscal year until maturity in May 2026. ​
