PALATIN TECHNOLOGIES INC 8-K

What Happened

(PTN) filed a Form 8-K (dated May 18, 2026) announcing that, with Board authorization, it notified the NYSE it will voluntarily withdraw the listing of its common stock from the NYSE American and transfer the listing to the Nasdaq Capital Market. Nasdaq has approved the listing. The company expects NYSE trading to cease at the close on May 28, 2026, and Nasdaq trading to begin on May 29, 2026. The common stock will continue to trade under the symbol "PTN." The filing also references a press release issued May 18, 2026.
