This prospectus supplement supplements the prospectus dated December 2, 2025, (the “Prospectus”), which forms a part of our registration statement on Form S-1 (No. 333-291024). This prospectus supplement is being filed to update and supplement the information in the Prospectus with the information contained in our Form 8-K, filed with the Securities and Exchange Commission (the “SEC”) on February 6, 2026 (the “Form 8-K”). Accordingly, we have attached the Form 8-K to this prospectus supplement. This prospectus supplement should be read in conjunction with the Prospectus, which is to be delivered with this prospectus supplement, and is qualified by reference thereto, except to the extent that the information in this prospectus supplement updates or supersedes the information contained in the Prospectus.

Our common stock is listed on The Nasdaq Stock Market under the symbol “SAFX.” On February 5, 2026, the last reported sale price of our common stock was $0.1548 per share. You are urged to obtain current market data and should not use the market price as of February 5, 2026, as a prediction of the future market price of our common stock.

We are an “emerging growth company” and a “smaller reporting company,” as those terms are defined under the federal securities laws, and as such, have elected to comply with certain reduced public company reporting requirements for the registration statement of which this prospectus forms a part and future filings. See “Prospectus Summary – Implications of Being an Emerging Growth Company and Smaller Reporting Company” in the Prospectus.

Investing in our securities involves significant risk. You should carefully read and consider the information referred to under “Risk Factors” beginning on page 11 of the Prospectus and under similar headings in any amendments or supplements to the Prospectus for a discussion of certain risks that you should consider in connection with an investment in our securities.

We may amend or supplement this prospectus from time to time by filing amendments or supplements with the SEC. We urge you to read the entire prospectus, any such amendments or supplements, any free writing prospectuses we may file with the SEC, and any documents incorporated by reference into this prospectus or any prospectus supplement carefully before you make your investment decision.

Neither the SEC nor any state securities commission has approved or disapproved of these securities or passed upon the accuracy or adequacy of this prospectus. Any representation to the contrary is a criminal offense.

The date of this prospectus supplement is February 6, 2026
