Amendment Description	EXPLANATORY NOTERTB Digital, Inc. (the “Company”) is filing this Amendment No. 1 on Form 10-Q/A (this “Amendment”) to amend its Quarterly Report on Form 10-Q for the quarter ended June 30, 2026, filed with the Securities and Exchange Commission on August 14, 2026 (the “Original Report”).The sole purpose of this Amendment is to correct an Inline XBRL tagging error in Note 2 to the Company’s unaudited condensed consolidated financial statements. The Original Report correctly disclosed in the human-readable document that the Price Protection Feature is capped at $15.0 million; however, the amount was incorrectly tagged in the machine-readable XBRL data using a share-based concept and “shares” unit rather than a monetary concept and USD unit.This Amendment corrects the XBRL tagging only. It does not change the human-readable disclosure, financial statements, any reported amount or the underlying terms of the transaction. Except for this correction, this Amendment does not amend, update or modify any other disclosure in the Original Report.
