Nasdaq files to delist Artius II Acquisition securities

What happened

On August 19, 2026, Nasdaq filed a Form 25 with the SEC to delist the securities of Artius II Acquisition Inc., a blank check company. The filing covers the company's Class A ordinary shares, rights, and units.

The form indicates the delisting is being done under SEC Rule 12d2-2(b), which means the exchange has complied with its rules to strike the securities from listing. The filing does not specify whether the delisting is voluntary or initiated by Nasdaq, nor does it state the reason.

Artius II Acquisition Inc. is a special purpose acquisition company (SPAC) based in New York. Shares closed at $10.59 on the event date, unchanged from the previous close.

Context

The filing lists three classes of securities: Class A Ordinary Share, Right, and Unit. In a typical SPAC structure, units are often composed of one ordinary share and a fraction of a warrant or right, and they may be traded separately.

A Form 25 is the notification a stock exchange files when removing a security from listing and registration. It is often used when a company is acquired, merges, or otherwise ceases to be publicly traded, but the filing itself does not reveal the underlying cause.

What this means

A Form 25 is how a security is removed from an exchange listing; either the company or the exchange can file one. Here, Nasdaq filed it, certifying it has reasonable grounds to believe it meets the requirements for delisting.

This filing does not say why the delisting is occurring. For a SPAC, common reasons could include the completion of a business combination, a liquidation, or a failure to meet listing standards, but none of these are confirmed by the document.

Once the Form 25 is effective, the securities will no longer trade on Nasdaq. The company may be required to file additional forms, such as a Form 15 to suspend reporting obligations, depending on the circumstances—but that is not stated in this filing.
