Analysis · SBXD · Real Estate & Construction
The NYSE has commenced proceedings to delist SilverBox Corp IV's units, Class A ordinary shares, and warrants after the company fell below the $40 million average aggregate global market capitalization requirement for listed acquisition companies. Trading is suspended immediately, and the securities began trading on the OTCID Basic Market on September 28, 2026 under new tickers SBXUF, SBXDF, and SBXWF. This is a critical event for a SPAC that has already seen massive redemptions — only $10.5 million remained in the trust account as of the last 10-Q — and is still pursuing a merger with Parataxis Holdings. Delisting removes exchange liquidity and can accelerate further redemptions or impair the pending merger's viability.
