See Note 15, Fair Value Measurements for further information.

As discussed in Note 3, Credit Agreement and Securities Purchase Transaction, the Company issued to the Purchaser, one warrant to purchase 43,276,194 shares of Common Stock. The warrant has a ten-year term, a $0.01 per share exercise price, and is exercisable at the Purchaser’s discretion for cash or on a cashless basis. Upon an acceleration under the Credit Agreement, the Company could be required to purchase the warrant from the holder at an amount equal to the most recently quoted price. Following stockholder approval on September 10, 2024, the Warrant Conversion Cap increased to 49.9%. See Note 3, Credit Agreement and Securities Purchase Transaction for additional information on this transaction.

Following the Initial Draw, on three separate predetermined draw dates upon the achievement of the corresponding performance milestone for each such draw date, the Company will receive additional funds under the Credit Agreement and will issue securities under the SPA in an amount equal to the applicable percentage, up to an aggregate of 33.0% ownership limitation on a fully-diluted basis at such time the Delayed Draw Term Loan is fully drawn. Although these contingent warrants are not issued or exercisable until additional draws occur, they meet the definition of a derivative and are recognized at fair value with changes in fair value reported in the Condensed Consolidated Statements of Operations and Comprehensive (Loss) Income.
