August 2025 Private Placement
On August 21, 2025, the Company entered into the August 2025 Purchase Agreement with the purchasers party thereto, pursuant to which the Company agreed to sell securities to such purchasers in the August 2025 Private Placement. The August 2025 Purchase Agreement provided for the sale and issuance by the Company to the purchasers of: (i) an aggregate of 5,251,349 shares of its common stock at a purchase price of $3.95 per share, (ii) for certain purchasers, in lieu of common stock, an aggregate of 1,077,764 Pre-Funded Warrants to purchase up to the same number of shares of its common stock, and (iii) an aggregate of 2,848,096 Purchase Warrants to purchase up to the same number of shares of its common stock. The Pre-Funded Warrants were issued for a purchase price equating to $3.949 per Pre-Funded Warrant (which was the per share purchase price for the common stock issued in the August 2025 Private Placement, less the $0.001 per share unfunded exercise price for each Pre-Funded Warrant). On October 6, 2025, certain purchasers from the August 2025 Private Placement exercised an aggregate of 1,077,764 Pre-Funded Warrants previously issued to them pursuant to the August 2025 Purchase Agreement. Each such exercise was made pursuant to the cashless exercise provision of the applicable Pre-Funded Warrant, such that an aggregate of 166 shares of common stock were withheld in lieu of a cash payment of the $0.001 exercise price for each Pre-Funded Warrant, and the exercising purchasers were issued an aggregate of 1,077,598 shares of common stock. Following the October 2025 Cashless Exercise, no Pre-Funded Warrants remained issued and outstanding. The Purchase Warrants were issued with an exercise price of $5.50 per share; as of March 31, 2026, no Purchase Warrants had been exercised. As of March 31, 2026, the Company had received aggregate net proceeds of $23.4 million from the August 2025 Private Placement, after deducting placement expenses of $1.6 million. The August 2025 Private Placement closed on August 26, 2025.
Also on August 21, 2025, in connection with the August 2025 Purchase Agreement, the Company entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with the purchasers in the August 2025 Private Placement. Pursuant to the Registration Rights Agreement, the Company agreed to prepare and file a registration statement with the SEC for purposes of registering the resale of the common stock and the shares of common stock issuable upon exercise of the Pre-Funded Warrants and Purchase Warrants (collectively, the “Warrant Shares”) purchased by the purchasers in the August 2025 Private Placement, and any shares of common stock issued as a dividend or other distribution with respect to, in exchange for or in replacement of such common stock or Warrant Shares. On September 3, 2025, the Company filed a Registration Statement on Form S-3 (File No. 333-289997) (the “2025 Resale Registration Statement”) with the SEC in relation to the registration for re-sale of the common stock and Warrant Shares from the August 2025 Private Placement. The SEC declared the 2025 Resale Registration Statement effective on September 8, 2025.
The Purchase Warrants have an exercise price of $5.50 per share of common stock, are exercisable immediately following their issuance, and will expire on September 8, 2030. The Purchase Warrants contain standard adjustments to the exercise price including for stock splits, stock dividends or distributions, certain other dividends or distributions and certain reorganizations. The Purchase Warrants also include certain rights upon the occurrence of a “fundamental transaction” (as described in the Purchase Warrants).

The proceeds received from the sale of equity classified warrants and shares of common stock in a bundled transaction are allocated based on the relative fair values of warrants and shares of common stock with no changes in fair value of warrants recognized after the issuance date.
The Purchase Warrants and Pre-Funded Warrants were classified as a component of stockholders’ equity within additional paid-in-capital and were recorded at the issuance date using a relative fair value allocation method. The Purchase Warrants and Pre-Funded Warrants are equity classified because they are freestanding financial instruments that are legally detachable and separately exercisable from the equity instruments, are immediately exercisable, do not embody an obligation for the Company to repurchase its shares, permit the holders to receive a fixed number of common shares upon exercise, are indexed to the Company’s common stock and meet the equity classification criteria. In addition, such Purchase Warrants do not provide any guarantee of value or return. The Company valued the Purchase Warrants at issuance using the Black-Scholes valuation model and allocated proceeds from the sale proportionately to the common stock and Purchase Warrants, of which approximately $3.7 million was allocated to the Purchase Warrants and recorded as a component of additional paid-in-capital.

As of March 31, 2026, the Company had 2,848,096 Purchase Warrants issued and outstanding at an exercise price of $5.50 per share to purchase shares of the Company's common stock.
