Filing notes and footnotes

Explanation of responses 2 footnotes

Footnote F1

On June 12, 2026, IBX, LLC perfected its security interest in 279,438 shares of the Issuer's Class A Common Stock to secure the payment in full of the amount owed to it under a non-negotiable promissory note made by an unaffiliated third party in favor of IBX, LLC and gave notice of default to such third party. On that date, the outstanding amount due under the note was $3,727,858. The balance owed under the note will increase at the rate of $1,414.00 per day, plus costs and expenses of collection. Based on the closing price for such shares on NASDAQ on June 12, 2026, of $18.59 per share, 200,530 shares would have been required to satisfy the note on that date. However, upon the actual transfer of the shares of the Issuer's Class A Common Stock, the number of shares transferred to satisfy the then-outstanding amount under the note may be different from that number up to 279,438 shares.

Footnote F2

Consists of (i) 471,774 shares of Class A Common Stock held by GM Enterprises, LLC, (ii) 3,951,679 shares of Class A Common Stock held by X-Energy Holdings, LLC, (iii) 12,973 shares of Class A Common Stock held by IBX Opportunity GP, Inc., (iv) 592,651 shares of Class A Common Stock held by X-energy KG Parent, LLC and (v) 279,438 shares of Class A Common Stock held by IBX, LLC.
