Equity [Abstract]  
Stockholders' Equity Stockholders’ Equity
Common and Preferred Stock
The Company’s amended and restated certificate of incorporation authorizes the issuance of up to 175,000,000 shares of $0.0001 par value common stock and up to 25,000,000 shares of $0.0001 par value undesignated preferred stock. The Company’s Board of Directors (the “Board”) may designate the rights, preferences, privileges, and restrictions of the preferred stock, including dividend rights, conversion rights, voting rights, terms of redemption, liquidation preference, and number of shares constituting any series or the designation of any series. The issuance of preferred stock could have the effect of restricting dividends on the Company’s common stock, diluting the voting power of the Company’s common stock, impairing the liquidation rights of the Company’s common stock, or delaying or preventing a change in control. As of September 30, 2026, no shares of preferred stock were outstanding.

of $1.5299 per pre-funded warrant. Gross proceeds to the Company totaled $50.1 million before deducting $3.3 million of placement agent fees and other expenses.

Gross proceeds to the Company totaled $50.1 million before deducting $3.2 million of placement agent fees and other expenses.
The pre-funded warrants issued in the Initial Closing and the Second Closing have an exercise price of $0.0001 per Initial Closing Warrant Share and Second Closing Warrant Share, subject to customary adjustments, are exercisable at any time, do not expire until exercised in full, and are exercisable on a net exercise “cashless” basis. The pre-funded warrants may not be exercised if the aggregate number of shares of common stock beneficially owned by the holder thereof immediately following such exercise would exceed a specified beneficial ownership limitation, not to exceed 19.99%.

In connection with the Initial Closing of the Private Placement, on November 3, 2025, the Company filed a registration statement on Form S-3 (the “Initial Registration Statement”) with the SEC, which subsequently became effective, to register the Initial Closing Shares for resale and, as applicable, the Initial Closing Warrant Shares. Following the Second Closing, the Company filed a second registration statement (the “Second Registration Statement”) with the SEC on August 6, 2026, which subsequently became effective, to register the Second Closing Shares for resale and, as applicable, the Second Closing Warrant Shares.
The Company concluded that the pre-funded warrants issued in the Initial Closing and the Second Closing met the conditions to be classified as equity instruments.
