Item 1.01 Entry into a Material Definitive Agreement.

On March 5, 2026, REalloys Inc. (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with Clear Street LLC (the “Representative”), as the representative of the several underwriters named therein (the “Underwriters”), relating to an underwritten public offering (the “Offering”) of 2,702,702 shares (the “Shares”) of the Company’s common stock, par value $0.001 per share (“Common Stock”). The public offering price per Share was $18.50 and the Underwriters purchased the Shares pursuant to the Underwriting Agreement at a price per Share of (i) $17.39 in connection with 2,349,037 Shares sold to investors sourced by the Underwriters and (ii) $18.2225 for 353,665 Shares sold to investors sourced by the Company. Pursuant to the Underwriting Agreement, the Company also granted the Underwriters a 30-day option to purchase up to an additional 396,963 shares of the Common Stock on the same terms as the Shares sold in the Offering. The Offering is expected to close on or about March 9, 2026 (the “Closing Date”).

Aggregate gross proceeds from the Offering are expected to be approximately $50 million, before deducting underwriting discounts and commissions and estimated expenses payable by the Company. The Company intends to use the net proceeds from the Offering for working capital and general corporate purposes.

The Underwriting Agreement additionally contains customary representations, warranties and covenants made by the Company, including an agreement by the Company that the Company may not, without the prior written consent of the Representative, assign, transfer, pledge, contract to sell, establish an open “put equivalent position”, or otherwise dispose of, or announce the offering of, or submit or file any registration statement, prospectus or prospectus supplement in respect of, any Shares, options, rights or warrants to acquire Common Stock or securities exchangeable or exercisable for or convertible into Common Stock until 60 days following the date of the Underwriting Agreement, subject to certain exceptions. In addition, the Company granted Clear Street LLC the right to participate with respect to any of the Company’s public or private offering of equity, equity-linked or debt securities, a debt or debt-like financing, or a restructuring transaction, for a period of 180 days after closing of the Offering.

The Underwriting Agreement also provides for customary indemnification by each of the Company and the Underwriters, severally and not jointly, for losses or damages arising out of or in connection with the Offering, including for liabilities under the Securities Act of 1933, as amended (the “Securities Act”), other obligations of the parties and termination provisions.

The Offering is being made pursuant to the Company’s registration statement on Form S-3 (File No. 333-284626), filed with the Securities and Exchange Commission (the “SEC”) on January 31, 2025, and declared effective on February 10, 2025, a base prospectus dated February 10, 2025, and a prospectus supplement dated March 5, 2026, and related registration statement on Form S-3 (File No. 333-294073), filed with the SEC on March 5, 2026 and effective upon filing.
