[1] | On May 14, 2025, we exchanged $70.8 million aggregate principal amount of our 2026 Notes for 2029 Notes on a one-for-one basis in the Convertible Note Exchange and recorded a reduction of an additional $10.0 million aggregate principal amount of our 2026 Notes to be equitized pursuant to the Equitization Transaction. The 2029 Notes are subject to a conversion arrangement that potentially increases the dilutive effect of conversion as described in “Note 6 — Debt.”
[2] | On May 12, 2025, the Company entered into Note Conversion Agreements to exchange $10.0 million of aggregate principal of our 2026 Notes for shares of our common stock reducing the effect of dilution on these notes. The Note Conversion Agreements provide for delivery of the common stock in three tranches. The above calculation assumes dilution to occur at the stock price at June 30, 2025. (For further details refer to “Note 6 — Debt”).
[3] | The 2026 Notes are subject to a capped call arrangement that potentially reduces the dilutive effect of conversion as described in “Note 6 — Debt.” Any potential impact of the capped call arrangement is excluded from this table.
