Insights

Equity markets and listing standards analyst

Palatin’s stock has been delisted from NYSE American and now trades only on the OTCQB, following a reverse split and temporary symbol change.

The company states that NYSE American determined its common stock was no longer suitable for listing under Section 1003(f)(v) of the NYSE American Company Guide because of a low selling price, and that delisting proceedings have begun. Trading on NYSE American was suspended on May 7, 2025, which typically reduces liquidity and visibility compared with a national exchange listing.

The shares have been quoted on the OTCQB Market, first under the symbol “PTNT”, then under “PTNTD” from August 12, 2025 to reflect a 1-for-50 reverse stock split. After a twenty trading day period under “PTNTD”, the symbol reverted to “PTNT” effective September 10, 2025. The reverse split and move off NYSE American are mechanically disclosed here; the longer-term impact depends on how trading volume and investor access evolve on OTCQB.
