Fiscal Third Quarter Ended March 31, 2023 Financial Results

Revenue
Total revenue consists of gross product sales of Vyleesi, net of allowances and accruals, and license and contract revenue.

Vyleesi gross product sales to pharmacy distributors were $3.4 million, with net product revenue of $1.2 million, compared to gross product sales of $1.3 million and net product revenue of $0.2 million for the comparable quarter last year. Gross product sales increased 165% and net product revenue increased 453% over the comparable quarter last year.

Operating Expenses
Total operating expenses were $8.5 million, compared to $8.0 million for the comparable quarter last year. The increase in operating expenses was mainly the result of higher spending on our marketing efforts of Vyleesi.

Cash Flows
Palatin's net cash used in operations was $1.4 million, compared to net cash used in operations of $9.5 million for the same period last year. The decrease in net cash used in operations is mainly due to the Company's receipt of proceeds from the sale of the State of New Jersey NOLs and working capital changes for the quarter ended March 31, 2023.

Net Loss
Palatin's net loss was $7.1 million, or $(0.63) per basic and diluted common share, compared to a net loss of $7.6 million, or $(0.80) per basic and diluted common share for the comparable quarter last year.

The decrease in net loss over the comparable quarter last year, was mainly due to an increase in net product revenue of Vyleesi of $1.0 million offset by an increase in operating expenses of $0.5 million.

Cash Position
As of March 31, 2023, Palatin's cash and cash equivalents were approximately $19.6 million plus $1.7 million of accounts receivables, compared to cash and cash equivalents of $21.2 million with $6.5 million of accounts and other receivables as of December 31, 2022, and $29.9 million with $1.8 million of accounts receivable as of June 30, 2022.

Based on its current operating plan, the Company believes that existing cash and cash equivalents and receivables will be sufficient to fund currently anticipated operating expenses through calendar year 2023.

About Melanocortin Receptor Agonists and Inflammation
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.

Many tissues and immune cells located in the eye (and other places, for example the gut and kidney) express melanocortin receptors, empowering our opportunity to directly activate natural pathways to resolve disease inflammation.

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.
