Warrant Liabilities | 6. Warrant Liabilities 2014 Warrant In January 2014, the Company issued a fully vested warrant to purchase 118,483 shares of the Company’s Series B convertible preferred stock (the "2014 Warrant") in connection with a loan and security agreement entered into in January 2014. The 2014 Warrant was immediately exercisable at an exercise price of $1.266 per share and has a contractual term of ten years from issuance. In January 2024, the 2014 Warrant was amended to extend the expiration date to the earlier of (i) the date that is 30 calendar days after the closing of the Company’s IPO and (ii) July 31, 2024. Upon the closing of the Company's IPO on February 6, 2024, the amended expiration date of the 2014 Warrant was determined to be March 7, 2024. The Company remeasures the fair value of the 2014 Warrant at the end of each reporting period, with any adjustments being recorded as a component of other income (expense) in the condensed consolidated statements of operations and comprehensive loss. Upon the closing of the IPO on February 6, 2024, the warrant to purchase 118,483 shares of the Company's Series B convertible preferred stock was converted to a warrant to purchase 55,211 shares of the Company's common stock. Accordingly, the 2014 Warrant was remeasured upon the closing of the IPO and marked to market to its fair value before being reclassified to equity. The 2014 Warrant was fully cashless exercised on the amended expiration date of March 7, 2024, as a result of which a total of 38,544 shares of common stock were issued to the warrant holder. July 2023 Warrants In July 2023, the Company issued fully vested warrants to purchase shares of the Company’s common stock in connection with the issuance of the amended and restated 2022 Convertible Notes (the "July 2023 Warrants"). The July 2023 Warrants were immediately exercisable for a variable number of shares based on the principal amount of the 2022 Convertible Notes, as amended, of $20.9 million, and an exercise price, at the holders’ choice, of (a) $17.9927 per share, (b) the lowest original issue price of shares of Preferred Stock of the Company issued in the Company’s next bona fide private preferred equity financing round, (c) in the event of any convertible note or similar convertible security financing, the conversion price contemplated by such convertible security, or (d) in the event of an IPO, the per share offering price to the public in such IPO. The July 2023 Warrants have a contractual term of ten years from issuance. They were not exercised from their inception through June 30, 2025. The fair value of the July 2023 Warrants at issuance was $9.9 million and was recorded as part of the warrant liabilities on the condensed consolidated balance sheet. The Company remeasures the fair value at the end of each reporting period, with any adjustments being recorded as a component of other income (expense) in the condensed consolidated statements of operations and comprehensive loss. Prior to the Company's IPO in February 2024, the fair value was determined using the Monte-Carlo simulation model, which was based on significant inputs that are not observable in the market and represented a Level 3 measurement. After the completion of its IPO, the fair value of the July 2023 Warrants was determined using the Black-Scholes valuation model with the following assumptions:
|  | June 30,
|  | 2025
Risk-free interest rate |  | 4.0%
Expected term (in years) |  | 8.0
Expected volatility |  | 60%
Expected dividend yield |  | 0%

September 2023 Warrants In September 2023, in connection with the issuance of the 2023 Notes, the Company issued fully vested warrants to purchase, at the holders’ choice, shares of the Company’s Series F Convertible Preferred Stock, the most senior series of Preferred Stock of the Company that is then authorized, or the Company’s common stock (the "September 2023 Warrants"). The September 2023 Warrants are immediately exercisable for a variable number of shares based on a total fixed dollar value of $4.2 million, and an exercise price, at the holders’ choice, of (a) $17.9927 per share of common stock or $8.3843 per share of Series F Convertible Preferred Stock, (b) the lowest original issue price of any series of Preferred Stock issued by the Company after the issuance date of the September 2023 Warrants, (c) the conversion or exercise price of any convertible debt security, option, or warrant issued by the Company after the issuance date of the September 2023 Warrants, or (d) the price at which the Company’s common equity was first sold to the public by the Company in a firm-commitment underwritten offering or otherwise. The September 2023 Warrants have a contractual term of ten years from issuance. They were not exercised from their inception through June 30, 2025. The fair value of the September 2023 Warrants at issuance was $2.6 million and was recorded as part of the warrant liabilities on the condensed consolidated balance sheet.
