As of September 30, 2024 and December 31, 2023, the Convertible Notes were no longer outstanding. Upon issuance, the Company elected the fair value option for the Convertible Notes in accordance with ASC 825, “Financial Instruments,” pursuant to which the entire instrument, including interest expense, is measured at fair value with the initial change in fair value deemed to be a capital contribution and any subsequent changes in fair value being recorded to other income (expense) on the unaudited condensed consolidated statements of operations and comprehensive (loss) income. During the three and nine months ended September 30, 2024 there were no fair value adjustments recognized as the Convertible Notes were no longer outstanding. The fair value adjustment recognized in other income (expense) was $4.8 million and $5.4 million for the three and nine months ended September 30, 2023, respectively. As a result of the Merger (Note 4), pursuant to the terms thereof, the Convertible Notes converted into shares of EIP Common Stock which were subsequently converted into the right to exchange such shares for 897,272 shares of the Company’s common stock (or, in certain cases, pre-funded warrants to purchase the Company’s common stock in lieu thereof). Accordingly, the Convertible Notes were adjusted to fair value prior to conversion by multiplying the trading price of the Company’s common stock at the date of the Effective Time and the 795,905 common shares and 101,367 pre-funded warrants issued upon conversion. The Company recorded a gain on the fair value adjustment of the Convertible Notes of $4.8 million and $5.4 million for the three and nine months ended September 30, 2023 and recorded $7.0 million to additional paid in capital for the issuance of common stock upon settlement of the Convertible Notes.
