Checkpoint

Checkpoint deemed the placement agent warrants it issued in connection with a registered direct offering (the “December 2022 Placement Agent Warrants”) to be classified as liabilities on the balance sheet as they contain terms for redemption of the underlying security that are outside its control. The December 2022 Placement Agent Warrants were recorded at the time of closing at a fair value determined by using the Black-Scholes model. Checkpoint will revalue the December 2022 Placement Agent Warrants at each reporting period thereafter for as long as they remain outstanding. At March 31, 2025 and December 31, 2024, the liability associated with the December 2022 Placement Agent Warrants was $0.3 million and $0.2 million, respectively.

A summary of the weighted average (in aggregate) significant unobservable inputs (Level 3 inputs) used in measuring the Checkpoint warrant liability that are categorized within Level 3 of the fair value hierarchy was as follows:

Avenue

Avenue has previously issued freestanding warrants to purchase shares of its common stock in connection with financing activities. Avenue’s outstanding warrants to purchase common stock were originally issued in October 2022 (the “October 2022 Warrants”). The October 2022 Warrants are classified as liabilities on the balance sheet as they contain terms for redemption of the underlying security that are outside of its control. In connection with the Avenue January 2023 registered direct offering in January 2023, the down-round price protection feature was triggered and the exercise price for the October 2022 Warrants was permanently adjusted to $116.25, which was the offering price for the Avenue registered direct offering in January 2023. The Black-Scholes model was used to value the October 2022 Warrants as of March 31, 2025 and December 31, 2024. At March 31, 2025 and December 31, 2024, the liability associated with the October 2022 Warrants was approximately $1,000 and $16,000, respectively.
