SilverBox Corp IV Receives NYSE Delisting Notice for Low Market Cap

What Happened
SilverBox Corp IV (SBXD) announced in an 8-K that on September 25, 2026 it received a written notice from NYSE Regulation that the NYSE Staff has determined to commence proceedings to delist the Company’s Units, Class A ordinary shares and warrants. The Staff found the company failed to meet the NYSE continued-listing standard for a listed acquisition company, which requires an average aggregate global market capitalization attributable to publicly-held shares of at least $40,000,000 over a consecutive 30 trading-day period. Trading on the NYSE was suspended as of the Notice date.

Key Details

• Date of Notice: September 25, 2026.
• Listing Rule: NYSE Listed Company Manual Section 802.01B (failure to meet $40,000,000 30-day market-cap standard).
• Securities affected: Units (one Class A share + 1/3 warrant), Class A ordinary shares, and Warrants.
• Trading status: NYSE trading suspended as of the Notice; effective September 28, 2026 the securities may trade OTC under tickers “SBXD.U” (Units), “SBXD” (Class A shares), and “SBXD.WS” (Warrants).
• Next steps: SilverBox has a right to seek review by an NYSE Board Committee; application to the SEC to delist is pending and subject to completion of applicable procedures and any appeal.

Why It Matters
A delisting determination can reduce liquidity and visibility for SilverBox’s securities and may affect holders’ ability to buy or sell at current prices. The company can appeal the decision, and trading will continue OTC if delisting proceeds, but investors should be aware of potential changes in trading venue, lower trading volumes, and implications for valuation and exit options.
