2024 Convertible Notes and 2017 Capped Call Transactions

On November 14, 2017, the Company issued $570.0 million aggregate principal amount of senior convertible notes due on November 15, 2024 (the “2024 Notes”) and, simultaneously, entered into capped call transactions with counterparties intended to minimize the impact of potential dilution upon conversion of the 2024 Notes (the “2017 Capped Calls”).

On September 14, 2022, the Company entered into separate, privately negotiated transactions to repurchase a portion of the outstanding 2024 Notes. The holders exchanged $150.6 million in aggregate principal value of 2024 Notes held by them for an aggregate payment of $248.6 million for full settlement of the principal value and accrued interest on such date. As a result of the repurchases, the Company entered into agreements with the 2017 Capped Calls counterparties to terminate a corresponding portion of the 2017 Capped Calls and received $26.3 million in cash.

On March 2, 2023, the Company entered into separate, privately negotiated exchange agreements with certain holders of the outstanding 2024 Notes (the “Exchange Agreements”). The Exchange Agreements resulted in an exchange of $313.5 million in aggregate principal value of the 2024 Notes for shares of the Company’s common stock (the “2024 Notes Exchange”), which closed on March 7, 2023 (the “Exchange Date”). In connection with the 2024 Notes Exchange, the Company issued approximately 4.5 million shares of the Company's common stock representing an agreed upon contractual exchange rate under each of the Exchange Agreements. The fair value of these shares issued was approximately $693.4 million. The Company also incurred approximately $6.9 million in third-party debt conversion costs. The exchange was not pursuant to the conversion privileges included in the terms of the debt at issuance and therefore was accounted for as a debt extinguishment.

The Company accounted for the debt extinguishment by recognizing the difference between the fair value of the shares of common stock transferred on the Exchange Date and the net carrying amount of the extinguished debt as a loss on debt extinguishment. Accordingly, on the Exchange Date, the Company: (i) reduced the carrying value of the 2024 Notes by $311.5 million, (ii) eliminated accrued interest of $1.5 million, and (iii) recorded a loss on debt extinguishment of $387.3 million, inclusive of the $6.9 million in third-party debt conversion costs, which is included in the unaudited condensed consolidated statement of operations and comprehensive loss. The outstanding principal balance of the 2024 Notes as of September 30, 2023 is approximately $105.8 million, which is convertible into approximately 1.4 million shares of Company common stock.

As a result of the exchange, the Company entered into agreements with the counterparties to the 2017 Capped Calls to terminate a portion of the 2017 Capped Calls in a notional amount corresponding to the principal amount of the 2024 Notes exchanged through the 2024 Notes Exchange and received approximately $80.6 million in cash from the counterparties, which was included in additional paid-in capital within the unaudited condensed consolidated balance sheets as of September 30, 2023.
