<div align='center'>3,975,901 Shares of Common Stock Issuable Upon Exercise of Warrants</div>

We are offering 3,975,901shares of our common stock, par value $0.0001 per share, issuable upon the exercise of 3,975,901 warrants originally issued on November 12, 2025 in a registered direct offering (the “warrants”).

Each warrant has a per share exercise price of $3.32. The warrants are currently exercisable and will expire on the second anniversary of the original issuance date. The warrants were initially exercisable solely on a cashless basis but will become exercisable against payment of the exercise price upon filing of this prospectus supplement registering exercise on such basis.

Our common stock trades on the New York Stock Exchange (“NYSE”) under the symbol “SRFM.” On November 21, 2025, the last reported sale price for our common stock on NYSE was $2.07 per share.

We are an “emerging growth company” as defined under U.S. federal securities laws and, as such, have elected to comply with reduced public company reporting requirements. See "Prospectus Supplement Summary – Our Corporate Information."
