The relationship between debt and equity has fluctuated for the observed period. Initially, the debt to equity ratio was not reported in 2019. However, beginning in 2020, a discernible pattern emerges, with the ratio initially increasing and then decreasing over time.

Convertible Senior Notes

The value of convertible senior notes, net, increased from US$575,864 thousand in 2020 to US$735,482 thousand in 2021, then experienced a modest increase to US$738,847 thousand in 2022, and a further increase to US$742,235 thousand in 2023. A significant increase occurred in 2024, reaching US$1,613,305 thousand, before decreasing substantially to US$983,449 thousand in 2025.

Stockholders’ Equity

Stockholders’ equity demonstrated consistent growth throughout the period. It increased from US$782,341 thousand in 2019 to US$957,432 thousand in 2020, US$1,041,203 thousand in 2021, US$1,410,505 thousand in 2022, US$2,025,354 thousand in 2023, US$2,714,363 thousand in 2024, and further to US$3,732,206 thousand in 2025.

Debt to Equity Ratio

The debt to equity ratio began at 0.60 in 2020, increasing to 0.71 in 2021. A subsequent decline was observed, falling to 0.52 in 2022 and further to 0.37 in 2023. The ratio increased to 0.59 in 2024, coinciding with the substantial increase in convertible senior notes, before decreasing significantly to 0.26 in 2025. This final decrease suggests a strengthening of the equity position relative to debt, despite the notes remaining substantial.

The fluctuations in the debt to equity ratio appear to be heavily influenced by changes in the value of convertible senior notes, particularly the large increase in 2024. While stockholders’ equity consistently increased, the impact of debt issuance and repayment, specifically the convertible notes, played a significant role in the overall ratio.
