Each warrant was exercisable, on a cash or a cashless basis, at the option of the holder, at any time on or prior to May 19, 2025. The warrant obligation, which was included in other long-term liabilities in the unaudited condensed consolidated balance sheets, was remeasured to fair value at the end of each reporting period. Changes in the fair value losses of the warrant obligation at the end of each period were recorded in the unaudited condensed consolidated statements of operations.

During the three and six months ended June 30, 2025, the Company did not recognize any expense or income as a result of changes in the fair value of the warrant obligation. For the three and six months ended June 30, 2024, the Company recognized income (expense) of $2.2 million and $(0.8) million, respectively. This amount was recorded to Other, net in the unaudited condensed consolidated statements of operations. The warrants expired on May 19, 2025 in accordance with their terms and therefore, there were no warrants outstanding as of June 30, 2025. The fair value of the warrant obligation as of December 31, 2024 was $0. See Note 16, "Other income (expense)" for further information.
