Corporate Update Public Offering On November 12, 2025, Palatin announced the closing of its upsized $18.2 million underwritten public offering ("Offering"), including the full exercise of the over-allotment option, consisting of 2,795,384 shares of common stock (or pre-funded warrants in lieu thereof) of the Company, together with Series J warrants to purchase up to 2,795,384 shares of common stock (or pre-funded warrants in lieu thereof), (the "Series J Warrants"), and Series K warrants to purchase up to 2,795,384 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 has an exercise price of $6.50 per share and will expire on the earlier of (i) the eighteen-month anniversary of the original issuance date or (ii) on the 31st 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 (oral small molecule or long-acting peptide) (the "FDA Exercise Period"). Each Series K Warrant has an exercise price of $8.125 per share and 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 automatically terminate. The gross proceeds from the Offering, before deducting the underwriting discounts and commissions and offering expenses, were approximately $18.2 million, with net proceeds amounting to $16.9 million. The Company may receive additional proceeds of up to $18.2 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. NYSE American As a result of the closing of the Offering, the Company regained compliance with NYSE American continued listing standard of the NYSE American Company Guide and all applicable requirements for continued listing on NYSE American. Effective November 12, 2025, the Company's common stock resumed trading on the NYSE American under the symbol "PTN." Fiscal Second Quarter Ended December 31, 2025, Financial Results Revenue For the second quarter ended December 31, 2025, Palatin recognized $116,036 in collaboration and license revenue compared to $0 for the comparable quarter last year. The increase in collaboration and license revenue is related to the Boehringer Ingelheim agreement which consisted of certain cost related reimbursements. Operating Expenses Total operating expenses were $7.4 million for the second quarter ended December 31, 2025, compared to $2.6 million for the comparable quarter last year. The increase in operating expenses was mainly due to the gain on the sale of Vyleesi recorded in the quarter ended December 31, 2024, which resulted in a decrease in net operating expenses, and an increase in operating expenses for the quarter ended December 31, 2025, consisting of an increase in costs on our MCR obesity development programs and higher compensation costs and professional fees. Other Income / (Expense) Total other income (expense), net was $64,687 for the second quarter ended December 31, 2025, compared to $168,841 for the comparable quarter last year. The decrease was a result of a decrease in investment income and foreign currency translation gain, offset by a decrease in interest expense incurred during the second quarter ended December 31, 2025. Cash Flows Palatin's net cash used in operations was $4.8 million for the second quarter ended December 31, 2025, and for comparable quarter last year. Net Loss Palatin reported a net loss for the second quarter ended December 31, 2025, of $7.3 million, or $(2.86) per basic and diluted common share, compared to a net loss of $2.4 million, or $(5.92) per basic and diluted common share, for the comparable quarter last year. Cash Position As of December 31, 2025, Palatin's cash and cash equivalents were $14.5 million, compared to cash and cash equivalents of $1.3 million at September 30, 2025, and $2.6 million as of June 30, 2025. Palatin currently expects a cash runway beyond the quarter ending March 31, 2027. In January 2026, as partial consideration for the rights to PL9643, the sublicensing agreement provided for upfront consideration in the form of non-cash debt cancellation of approximately $3,800,000, which is reflected in the Company's current liabilities as of December 31, 2025. The $3,800,000 million will be recognized as license revenue in the Consolidated Statements of Operations for the quarter ending March 31, 2026.

Melanocortin-4 Receptor Agonists Effect on Obesity Hypothalamic neurons expressing the melanocortin-4 receptor (MC4R) play a central role in regulating stored energy, food intake, and body weight. Genetic mutations that inhibit signaling through the MC4R pathway lead to hyperphagia, decreased energy expenditure and early-onset obesity; such mutations have been identified as the cause of several rare genetic obesity disorders. MC4R agonism represents an attractive target for potential obesity treatments. About Hypothalamic Obesity Hypothalamic obesity is a rare and severe form of obesity caused by dysfunction or damage to the hypothalamus, the region of the brain that regulates appetite, satiety, and energy balance. Hypothalamic obesity can occur as an acquired condition, most commonly after surgery or radiation therapy for brain tumors such as craniopharyngioma, or as a congenital disorder associated with genetic syndromes and developmental abnormalities affecting hypothalamic function. Individuals with hypothalamic obesity typically experience rapid, excessive weight gain, uncontrollable hunger, and profound metabolic disturbances that are resistant to conventional diet, exercise, and behavioral interventions. There are currently no approved pharmacologic treatments specifically indicated for hypothalamic obesity, representing a significant unmet medical need. About Prader-Willi Syndrome Prader-Willi syndrome (PWS) is a rare, complex genetic neurodevelopmental disorder caused by the loss of function of specific genes on chromosome 15. The condition is characterized by hyperphagia, impaired satiety, developmental delays, reduced muscle tone, endocrine abnormalities, and behavioral challenges. Individuals with PWS typically develop an intense and persistent drive to eat, beginning in early childhood, which can lead to severe obesity and related metabolic complications if not strictly managed. Current treatment approaches focus primarily on symptom management, including nutritional supervision, behavioral interventions, and growth hormone therapy, but there are no approved pharmacologic therapies that directly address hyperphagia or the underlying hypothalamic dysfunction associated with PWS. As a result, PWS represents a significant unmet medical need. About Melanocortin Receptor Agonists The melanocortin receptor ("MCR") system has effects on inflammation, immune system responses, metabolism, food intake, and sexual function. There are five melanocortin receptors, MC1R through MC5R. Modulation of these receptors, through use of receptor-specific agonists, which activate receptor function, or receptor-specific antagonists, which block receptor function, can have medically significant pharmacological effects. About Palatin Palatin is a biopharmaceutical company developing first-in-class medicines based on molecules that modulate the activity of the melanocortin receptor systems, with targeted, receptor-specific product candidates for the treatment of diseases with significant unmet medical need and commercial potential. Palatin's strategy is to develop products and then form marketing collaborations with industry leaders to maximize their commercial potential.
