Insights

Equity capital markets analyst

NYSE plans to delist AMBP warrants for low price, but shares remain listed.

Ardagh Metal Packaging S.A. discloses that the NYSE intends to delist its AMBP.WS warrants for “abnormally low selling price,” and has already halted trading. The company will not appeal, so the delisting path is effectively accepted, though the underlying structure of the warrants remains in place.

The warrants continue to be exercisable for one ordinary share at an exercise price of $11.50 per share until the earlier of August 4, 2026 or a redemption date described in the warrant agreement. This means warrant holders still have contractual rights, but the loss of an NYSE listing may reduce liquidity and make trading more difficult or costly through alternative venues, if any develop.

The company states that this NYSE action applies only to the warrants and does not affect the listing of its ordinary shares, which continue to trade on the NYSE under ticker AMBP. Investors may focus on how the delisting of a derivative security reflects on market sentiment, while the core equity listing and operations remain unchanged in this disclosure.
