In September 2024, the Company issued the Pre-Funded Warrant to purchase 2,900 shares of common stock, with an exercise price of $0.001 per share, for $2,897 in aggregate cash proceeds, which represents the September 2024 Offering price for the common stock of $1.00, less the per share exercise price. The Pre-Funded Warrant was fully exercised as of March 31, 2025.

In September 2024, the Company issued the Series A Warrants, which are exercisable for an aggregate of up to 6,000 shares of the Company’s common stock at an exercise price of $1.00 per share. The Series A Warrants were exercisable immediately and expire on September 4, 2029.

In September 2024, the Company issued the Series B Warrants, which are exercisable for an aggregate of up to 6,000 shares of the Company’s common stock at an exercise price of $1.00 per share. The Series B Warrants were exercisable immediately and expire on September 3, 2025.

The Series A Warrants and the Series B Warrants (collectively, the “September 2024 Warrants”) may be exercised, at the holder’s discretion, by (i) payment in full in immediately available funds for the number of shares of common stock purchased upon such exercise or (ii) if there is not an effective registration statement registering, or the prospectus contained therein is not available for the issuance of, the underlying common stock, a cashless exercise, in which case the holder would receive upon such exercise the net number of shares of common stock determined according to the formula set forth in the applicable September 2024 Warrant. However, a holder will not be entitled to exercise any portion of the September 2024 Warrants if the holder’s ownership of the Company’s common stock would exceed the Beneficial Ownership Limitation. The holder, upon notice to the Company, may increase the Beneficial Ownership Limitation to 9.99%, which increase shall not be effective until the 61st day after such notice is delivered to the Company.

In the event the Company enters into a Fundamental Transaction, as defined in the applicable September 2024 Warrant, the holders of the Series A Warrants and Series B Warrants will be entitled to receive, upon exercise of these warrants, the kind of amounts of securities, cash, or other property that the holders would have received had they exercised these warrants immediately prior to such Fundamental Transaction without regard to the Beneficial Ownership Limitation contained in such September 2024 Warrant. In addition, upon a Fundamental Transaction, subject to certain limitations and exceptions, the holder of the Series A Warrant may put the warrant back to the Company for an amount of cash equal to the Black-Scholes value of the remaining unexercised portion of the Series A Warrant, however, if such Fundamental Transaction is not considered within control of the Company, and not approved by the Company's Board of Directors, then the holder of the Series A Warrant would not be able to put the Series A Warrant back to the Company for cash.

The September 2024 Warrants are classified as a component of stockholders’ equity within additional paid-in capital and were recorded at the September 2024 Public Offering issuance date. The September 2024 Warrants are equity classified because they (i) are freestanding financial instruments that are legally detachable and separately exercisable from the equity instruments, (ii) are immediately exercisable, (iii) do not embody an obligation for the Company to repurchase its shares, (iv) permit the holders to receive a fixed number of shares of common stock upon exercise, (v) are indexed to the Company’s common stock, and (vi) meet the equity classification criteria. In addition, such September 2024 Warrants do not provide any guarantee of value or return.

2021 Warrants

In February 2021, the Company issued warrants (the "2021 Warrants"), exercisable for up to 273 shares of the Company’s common stock at an exercise price of $12.81 per share. The 2021 Warrants were exercisable immediately and expire on February 11, 2026. The 2021 Warrants may be exercised, at the holder's discretion, by (i) payment in full in immediately available funds for the number of shares of common stock purchased upon such exercise or (ii) if there is not an effective registration statement registering, or the prospectus contained therein is not available for the issuance of, the underlying common stock, a cashless exercise, in which case the holder would receive upon such exercise the net number of shares of common stock determined according to the formula set forth in the 2021 Warrant. However, a holder will not be entitled to exercise any portion of the 2021 Warrants if the holder’s ownership of the Company’s common stock would exceed the Beneficial Ownership Limitation. The holder, upon notice to the Company, may increase the Beneficial Ownership Limitation to 9.99%, which increase shall not be effective until the 61st day after such notice is delivered to the Company.

The 2021 Warrants will be automatically exercised on a cashless basis on their expiration date. The 2021 Warrants also contain a put option, under which, if the Company enters into a Fundamental Transaction, as defined in the 2021 Warrants, the Company or any successor entity will, at the option of a holder of a 2021 Warrant, exercisable concurrently with or at any time within 30 days after the consummation of such Fundamental Transaction, purchase such holder’s 2021 Warrant by paying to such holder an amount of cash equal to the Black-Scholes value of the remaining unexercised portion of such holder’s 2021 Warrant within five trading days after the notice of exercise by the holder of the put option. Because of this put-option provision, the 2021 Warrants are classified as a liability and are marked to market at each reporting date.

The warrant liability related to the 2021 Warrants is measured at fair value upon issuance and at each reporting date using certain estimated inputs, which are classified within Level 3 of the fair value hierarchy. The following assumptions were used in the Black-Scholes Model to measure the fair value of the 2021 Warrants:

The June 2020 Investor Warrants  may be exercised, at the holder's discretion, by (i) payment in full in immediately available funds for the number of shares of common stock purchased upon such exercise or (ii) if there is not an effective registration statement registering, or the prospectus contained therein is not available for the issuance of, the underlying common stock, a cashless exercise, in which case the holder would receive upon such exercise the net number of shares of common stock determined according to the formula set forth in the June 2020 Investor Warrant. However, a holder will not be entitled to exercise any portion of the June 2020 Investor Warrants if the holder’s ownership of the Company’s common stock would exceed the Beneficial Ownership Limitation. The holder, upon notice to the Company, may increase the Beneficial Ownership Limitation to 9.99%, which increase shall not be effective until the 61st day after such notice is delivered to the Company.

Alternatively, the Company or any successor entity will, at the option of a holder of a June 2020 Investor Warrant, exercisable concurrently with or at any time within 30 days after the consummation of such Fundamental Transaction, purchase such holder’s June 2020 Investor Warrant by paying to such holder an amount of cash equal to the Black-Scholes value of the remaining unexercised portion of such holder’s June 2020 Investor Warrant. Because of this put-option provision, the June 2020 Investor Warrants are classified as a liability and are marked to market at each reporting date.

Because of the put-option provision in the June 2020 Placement Agent Warrants, these warrants are classified as a liability and are marked to market at each reporting date.

However, a holder will not be entitled to exercise any portion of the December 2019 Warrants if the holder’s ownership of the Company’s common stock would exceed the Beneficial Ownership Limitation.
