SilverBox Corp IV Faces NYSE Delisting Over Market Capitalization Standards

SilverBox Corp IV has received notice from the New York Stock Exchange that it will be delisted because its average global market capitalization fell below the required threshold. The company's securities, including units, Class A ordinary shares, and warrants, are suspended from trading on the NYSE effective September 25, 2026.

The staff of NYSE Regulation determined that the company failed to maintain an average aggregate global market capitalization of at least $40,000,000 over a consecutive 30-trading-day period. This determination was made pursuant to Section 802.01B of the NYSE Listed Company Manual. As a result, the exchange has commenced proceedings to remove the company's listed securities.

The company's units, each consisting of one Class A ordinary share with a par value of $0.0001 and one-third of one redeemable warrant, are among the affected instruments. Each whole warrant is exercisable for one Class A ordinary share at an exercise price of $11.50. The delisting notice covers all three classes of securities: the units (SBXD.U), the Class A ordinary shares (SBXD), and the redeemable warrants (SBXD.WS).

Trading in these securities on the NYSE has been suspended as of the date of the notice. However, SilverBox Corp IV retains the right to appeal this decision to a Committee of the Board of Directors of the NYSE. An application to the Securities and Exchange Commission to formally delist the securities is currently pending, subject to the completion of all applicable procedures, including any potential appeal by the company.

If the delisting proceeds without a successful appeal, the securities will transition to the over-the-counter market effective September 28, 2026. Investors will be able to quote and trade the units under the ticker SBXD.U, the Class A ordinary shares under SBXD, and the warrants under SBXD.WS in that market. The company is incorporated in the Cayman Islands and maintains its principal executive offices in Austin, Texas.

Stephen Kadenacy, Chief Executive Officer of SilverBox Corp IV, signed the Form 8-K report on September 25, 2026. The filing confirms that no other changes to the company's status or structure are reported in this specific document beyond the delisting proceedings initiated by the exchange staff.
