12. CONVERTIBLE NOTES

 

In October 2025, we issued $150,000,000 aggregate principal amount of 4.00% convertible senior notes due 2030 (the “2030 Notes”), including the exercise in full by the initial purchasers of the 2030 Notes of their option to purchase up to an additional $15,000,000 principal amount of the 2030 Notes.

 

The Notes were issued pursuant to, and are governed by, an indenture (the “Base Indenture”), dated as of October 2, 2025, between the Company and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”), as supplemented by a first supplemental indenture (the “Supplemental Indenture,” and the Base Indenture, as supplemented by the Supplemental Indenture, the “Indenture”), dated as of October 2, 2025, between the Company and the Trustee. The net proceeds from the 2030 Notes offering, after deducting underwriting discounts and commissions and estimated offering expenses, were approximately $143.7 million, including the proceeds from the Underwriters’ exercise of their over-allotment option in full.

 

The 2030 Notes are senior and unsecured obligations and bear interest at a coupon rate of 4.00% per annum, with interest payable semi-annually in arrears on April 1 and October 1 of each year, beginning on April 1, 2026. The 2030 Notes will mature on October 1, 2030, unless earlier converted, redeemed or repurchased in accordance with their terms. The unamortized debt issuance costs as of December 31, 2025 was $6.3 million and were reported as a direct deduction from the face amount of the 2030 Notes. While the 2030 Notes bear a 4.00% stated interest rate, the effective interest rate for the notes as of December 31, 2025 was 11.7%, primarily reflecting the accretion of debt issuance costs.

 

Noteholders may convert their 2030 Notes at their option prior to the close of business on the second scheduled trading day immediately preceding the maturity date. The conversion rate is initially 240.3846 ordinary shares per $1,000 principal amount of the 2030 Notes (equivalent to an initial conversion price of $4.16 per ordinary share), which represents an approximately 30% conversion premium over the last reported sale price of $3.20 per ordinary share on the Nasdaq Capital Market on September 29, 2025. The conversion rate is subject to customary adjustments upon the occurrence of certain events, such as the interest make-whole conversion rate adjustment, or conversion upon a make-whole fundamental change, as described in the Indenture.

 

Holders of the 2030 Notes have a one-time noncontingent right to require the Company to repurchase for cash all or any portion of their respective notes at a repurchase price equal to 100% of the principal amount of such notes to be repurchased, plus any accrued and unpaid interest to, but excluding the repurchase date on October 1, 2028.

 

Under the interest make-whole conversion rate adjustment, the holders of the 2030 Notes are able to convert at any time during the period from, and including, the date that is six months after the last date of original issuance of the notes until the close of business on the business day immediately preceding September 15, 2028 (other than a conversion in connection with a make-whole fundamental change), the Company will increase the conversion rate per US$1,000 principal amount of the 2030 Notes to be converted by a number of ordinary shares.

 

We may not redeem the 2030 Notes prior to October 6, 2028. We may redeem for cash all or any portion of the 2030 Notes, at our option, on or after October 6, 2028 and prior to the 31st scheduled trading day immediately preceding the maturity date, if the last reported sale price of our ordinary shares has been at least 130% of the conversion price for the 2030 Notes 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 we provide notice of optional redemption at a redemption price equal to 100% of the principal amount of the 2030 Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.

If a “Fundamental Change” (as defined in the Indenture) occurs, then, subject to certain conditions and except as set forth in the Indenture, noteholders may require the Company to repurchase their 2030 Notes at a cash repurchase price equal to the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date. The definition in the Indenture of a Fundamental Change includes certain business combination transactions involving the Company and certain de-listing events with respect to the ordinary shares.

 

The Indenture contains customary terms and covenants, including that upon certain events of default either the Trustee or the holders of at least 25% in aggregate principal amount of the outstanding 2030 Notes may declare 100% of the principal of, and accrued and unpaid interest, if any, on, all the 2030 Notes to be due and payable.

 

The conversion features embedded in the 2030 Notes met the criteria to be bifurcated from the debt host contract under ASC 815 and recognized separately at fair value. The total proceeds received were first allocated to the fair value of the derivative liability, and the remaining proceeds allocated to the host. The host is subsequently measured using the effective interest method, and the derivative liability is measured at fair value, with changes in fair value recorded as derivative gain in the consolidated statements of operations. The 2030 Notes are classified as non-current liabilities as of December 31, 2025.

About Debt Disclosures

Debt disclosures detail a company's borrowing structure — the types of instruments, interest rates, maturity schedule, and covenant restrictions that define its financial obligations and flexibility. This section is essential for assessing refinancing risk, interest rate exposure, and the margin of safety against financial distress.

Key signals: the maturity schedule reveals concentration risk — large maturities within 1-2 years during tight credit markets can force dilutive refinancing or asset sales. Compare the fair value of debt against carrying amount to gauge whether the market views the company's credit risk differently than the balance sheet suggests. Watch covenant compliance disclosures for tightening cushions, especially leverage and interest coverage ratios. Variable-rate debt exposure quantifies sensitivity to interest rate changes. Secured versus unsecured mix affects recovery rates and future borrowing capacity. Compare net debt-to-EBITDA against industry peers and covenant limits to assess financial health.
