RECAPITALIZATION | NOTE 4 — RECAPITALIZATION IPO warrants In connection with Nubia’s initial public offering in 2022, 123,500 public warrants and 108,100 Private Warrants were issued, all of which remain outstanding and became warrants for the Common stock in the Company. The Company evaluated the IPO warrants and determined that it is a freestanding equity-linked contract within the scope of ASC 815-40. Based on this guidance, the Company concluded that the IPO warrants qualify for equity classification. HBC Holdback Shares The Company and G3 included a provision in the Merger Agreement that adjusts the aggregate share consideration to be paid to the shareholders of HBC if the G3 Tax Lien is not released prior to closing. Specifically, 4,000 shares of Solidion common stock, issuable to the HBC shareholders as part of the Merger Consideration at or following closing, depending on whether the G3 Tax Lien was settled by G3 prior to closing. See Note 6 for further discussion regarding Holdback Shares related to the G3 Tax Lien. As of the Merger closing and the year ended December 31, 2025, the G3 Tax Lien remained unresolved by G3, and the 4,000 holdback shares had not been issued as of December 31, 2025. HBC Earnout Arrangement As noted in Note 1, in connection with the Merger, HBC shareholders are entitled to up to 450,000 shares if certain post merger per share market prices are achieved. The Company evaluated the Earnout Arrangement and determined that it is a freestanding equity-linked contract within the scope of ASC 815-40. Based on this guidance, the Company concluded that the Earnout Arrangement qualifies for equity classification. As the merger has been accounted for as a reverse recapitalization, the fair value of the Earnout Arrangement has been accounted for as an equity transaction as of the Closing Date of the Merger. The Company utilized a Monte Carlo simulation analysis to determine the fair value of the Earnout Arrangement at the date of the merger, which included the following assumptions: stock price of $226.50, risk free rate of 3.98%, volatility of 85%, dividends yield of 0% and duration of 4 years. On October 9, 2025, the Company issued 450,000 shares of its common stock to G3 pursuant to the earnout provisions of the Merger Agreement. These shares represent the full amount of the Earnout Shares described above. See Note 1 for more details. | NOTE 4 — RECAPITALIZATION As discussed in Note 1, the Merger was accounted for as a common control transaction with respect to HBC which is akin to a reverse recapitalization.
