(OTCQB: PTNT) ("Palatin" or the "Company"), a biopharmaceutical company developing first-in-class medicines based on molecules that modulate the activity of the melanocortin receptor system, today announced the pricing of its underwritten public offering. The offering was led by healthcare-focused, high-quality institutional investors and included participation from the Company's Chief Executive Officer, Chief Financial Officer/Chief Operating Officer, and certain board members, of 2,430,769 shares of common stock (or pre-funded warrants in lieu thereof) of the Company, together with Series J warrants to purchase up to 2,430,769 shares of common stock (or pre-funded warrants in lieu thereof), (the "Series J Warrants"), and Series K warrants to purchase up to 2,430,769 shares of common stock (or pre-funded warrants in lieu thereof), (the "Series K Warrants"), at a combined public offering price of $6.50 per share of common stock and accompanying Series J and Series K warrants (the "Offering").

Each Series J Warrant will have an exercise price of $6.50 per share and will be immediately exercisable. The Series J Warrants will expire on the earlier of (i) the eighteen-month anniversary of the original issuance date or (ii) on the 31^st calendar day following the date that the Company receives the U.S. Food and Drug Administration ("FDA") acceptance of the Company's Investigational New Drug for an in-house obesity treatment compound (long-acting peptide or oral small molecule) (the "FDA Exercise Period"). Each Series K Warrant will have an exercise price of $8.125 per share and will be immediately exercisable. The Series K Warrants will expire on the five-year anniversary of the original issuance date, however, if a holder's Series J Warrants have not been terminated in accordance with their terms prior to the expiration of the FDA Exercise Period, such holder's Series K Warrants will terminate automatically upon the earlier of the (i) eighteen-month anniversary of the original issuance date of the Series J Warrant or (ii) the expiration of the FDA Exercise Period and prior to the five-year anniversary of the issuance of the Series K Warrant.

The closing of the Offering is expected to occur on or about November 12, 2025, subject to the satisfaction of customary closing conditions, including the resumption of trading of the Company's common stock on the NYSE American exchange. The gross proceeds from the Offering, before deducting the underwriting discounts and commissions and offering expenses, are expected to be approximately $15.8 million. In addition, Palatin has granted the underwriters a 45-day option to purchase up to an additional 364,615 common shares at the public offering price, less underwriting discounts, and commissions. The Company may receive additional proceeds of up to $15.8 million upon the cash exercise of the milestone related Series J Warrants, however, there is no guarantee that such warrants will be exercised and accordingly that the Company will receive any proceeds from the exercise thereof.

The Company intends to use the net proceeds from the Offering to support the development of its obesity program and for working capital and general corporate purposes.

Effective November 12, 2025, the Company's common stock is expected to resume trading on the NYSE American exchange under the symbol "PTN" and CUSIP "696077601".
