Reverse Recapitalization Impact on Equity

On February 24, 2026, the Company completed a reverse recapitalization transaction (the Merger) with Blackbox, which resulted in a recapitalization of the Company’s equity structure. As part of the transaction, the historical equity of REalloys was retroactively adjusted to reflect the legal capital structure of Blackbox.
Accordingly, all share and per-share amounts presented in the accompanying Condensed Consolidated Financial Statements have been retroactively adjusted to reflect this transaction.

In connection with the reverse recapitalization, the Company assumed 123,875 outstanding options of Blackbox. All such options were fully vested as of the closing date of the reverse recapitalization and did not require any post‑closing service from the holders. Accordingly, no additional compensation cost was recognized in connection with the assumption of these awards and no stock‑based compensation expense is recognized for these options in periods subsequent to the reverse recapitalization.

Following the transaction, the assumed options continue to be classified as equity instruments and are presented within additional paid‑in capital in the Company’s condensed consolidated balance sheets. After the Merger's close and on or before March 31, 2026, 62,500 options were exercised with a weighted average exercise price of $9.81, The options acquired have a weighted average remaining life of 6.1 years and weighted average exercise price of $9.81 per option.

Additionally, in connection with the reverse recapitalization, the Company assumed warrants for an aggregate of 100,245 common shares, with a weighted average remaining life of 2.6 years and weighted average exercise price of $13.19 per warrant. Following the transaction, the assumed options and warrants continue to be classified as equity instruments and are presented within additional paid‑in capital in the Company’s condensed consolidated balance sheets.

The Company's March 2025 warrants to purchase up to 5,000,000 shares of the Company's common stock at an exercise price of $10.00 per share were converted on the closing of the reverser recapitalization pursuant to the terms of the warrant and the Blackbox merger agreement. The converted aggregate number of the Company's common stock available under the warrants is 2,064,500 with a converted exercise price of $24.22 per share with a remaining life of approximately 9 years. Following the transaction, the warrants continue to be classified as equity instruments and are presented within additional paid‑in capital in the Company’s condensed consolidated balance sheets.

Series A Preferred Stock

At the close of the Merger, the Company recognized 10,000,000 shares of authorized preferred stock at $0.001 par value, 5,000,000 of which are designated as “Series A Convertible Preferred Stock” at $0.001 par value, and 2,400,000 of which are designated as “Series B Convertible Preferred Stock” at $0.001 par value.

Shares of the Series A Convertible Preferred Stock (the “Series A Stock”) rank pari passu with the Company’s Common Stock with respect to dividend and liquidation rights. Additionally, each share entitles the holder to 100 votes on matters submitted to Company stockholders. There are 3,269,998 shares of Series A Stock outstanding of which 1,634,999
shares each are owned by Gust Kepler, former CEO of Blackbox and Leonard Sternheim, the Company's CEO and Director.

Series A Preferred Stock Option Agreements

Prior to the closing of the Merger, Company and Gust Kepler, former CEO of Blackbox, executed an Option Agreement (the “Option Agreement”), pursuant to which the Company has the right to call for redemption and Gust Kepler shall have the right to cause the Company to redeem all of the issued and outstanding Series A Convertible Preferred Stock of the Company held by Gust Kepler in exchange for shares of Series A Convertible Preferred Stock of Blackbox.io, Inc. (“Blackbox Operating”), a Delaware corporation and wholly owned subsidiary of the Company. See Note 15 for details of the subsequent redemption of the call option by Mr. Kepler.

Contingent Value Rights Agreements

At the Closing of the Merger, the Company entered into a Contingent Value Rights Agreement (the “CVR Agreement”). The CVR Agreement provides that each share of Blackbox Common Stock held by stockholders immediately prior to the Merger's closing will receive a dividend of one contingent value right (“CVR”) entitling such holders to receive, in connection with certain transactions involving Blackbox Operating (a “CVR Transaction”), an amount equal to the net proceeds received by the Company at the closing of such transaction. A CVR Transaction is generally a transaction pursuant to which (i) Blackbox Operating grants, sells, licenses or otherwise transfers some or all of the rights to the Blackbox Operating assets, or other monetizing event of all or any part of the Blackbox Operating assets and (ii) the Company receives or Blackbox Operating determines to distribute net proceeds from such transaction as a dividend to its stockholders.

The CVR payment obligations will expire February 24, 2028. The CVRs are not be transferable, except in certain limited circumstances, are not be certificated or evidenced by any instrument, will not accrue interest and will not be registered with the SEC or listed for trading on any exchange. There is no guarantee that any CVR Transaction or payment pursuant thereto will be earned.

Additional Paid-In Capital

Additional paid-in capital primarily consists of amounts received in excess of par value from the issuance of common stock, as well as the impact of the reverse recapitalization transaction. Transaction costs directly attributable to the reverse recapitalization were recorded as a reduction to additional paid-in capital.

Warrants and Other Equity Instruments

The Company has issued warrants and other equity-linked instruments in connection with prior financing transactions. These instruments are evaluated for classification as either equity or liabilities in accordance with applicable accounting guidance.
Certain warrants are classified as liabilities and are remeasured at fair value each reporting period, with changes in fair value recognized in the condensed consolidated statements of operations.

Public Offering — March 9, 2026

On March 9, 2026, the Company completed an underwritten public offering (the “Offering”) pursuant to an effective registration statement on Form S-3, at a price of $18.50 per share. The Company issued 2,702,702 shares of common stock and received gross proceeds of $50.0 million, resulting in net proceeds of approximately $46.8 million after deducting underwriting discounts and offering expenses. Concurrently with the Offering, the Company terminated the at-the-market equity offering program (effective March 5, 2026), under which Blackbox had raised approximately $2.2 million between its inception and February 19, 2026, the last day of active sales under the program.

Special Warrants Conversion
Prior to the reverse recapitalization closing, REalloys Solutions Inc. had issued Special Warrants to certain investors for aggregate gross proceeds that were contractually entitled to convert into $38.0 million worth of REalloys shares upon a qualifying go-public transaction. At the February 24, 2026 closing, 2,093,664 shares of common stock were issued in connection with the conversion of all outstanding Special Warrants (2,093,664 shares × $18.15 per share = $38.0 million). The carrying value of the Special Warrant liability was adjusted from $34.6 million to $38.0 million (a $3.4 million loss on remeasurement) immediately prior to derecognition, and the $38.0 million was reclassified to additional paid-in capital upon conversion. See Note 10 - Fair Value Measurements.

SAFE Conversions

All outstanding Simple Agreements for Future Equity converted into 166,116 shares of common stock upon the February 24, 2026 qualifying go-public transaction. The aggregate carrying value of SAFE liabilities of $3.0 million was reclassified to additional paid-in capital upon conversion.

Series X and Series C Preferred Stock Conversion

On February 23, 2026, substantially contemporaneously with the Merger, the Company closed the second tranche of its previously announced private placement of Series X Preferred Stock, issuing 3,000 shares for aggregate gross proceeds of $3,000. Each share of Series X Preferred Stock was exchanged on the Effective Date for one share of Series C Convertible Preferred Stock of the combined company. The Company incurred costs of $400 related to the issuance of Series C Convertible Preferred Stock during the three months ended March 31, 2026. During the three months ended March 31, 2026, all outstanding shares of Series C Convertible Preferred Stock were converted into shares of the Company’s common stock in accordance with their terms. In accordance with the reverse recapitalization accounting, the Series X Preferred Stock outstanding at December 31, 2025 and at any time during the three months ended March 31, 2026, have been retroactively recast as Series C preferred stock, and the previously reported Series X Preferred Stock is no longer presented as a separate class of equity in these unaudited condensed consolidated balance sheets or unaudited condensed consolidated statements of mezzanine equity and stockholders’ equity, as all such amounts have been reflected on a retrospective basis consistent with the recapitalization presentation.
