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 for the quarter ended June 30, 2022, were $2.3 million, with net product revenue of $770,738, compared to gross product sales of $1.2 million, with net product revenue of $80,504, for the comparable quarter in 2021. Gross product sales increased 91% and net product revenue increased 857% over the comparable quarter in 2021.

Vyleesi gross product sales to pharmacy distributors for the fiscal year ended June 30, 2022, were $5.8 million, with net product revenue of $1.2 million, compared to gross product sales of $4.7 million, with negative net product revenue of $283,286, for the fiscal year ended June 30, 2021. Gross product sales increased 23% and net product revenue increased 530% over the fiscal year ended June 30, 2021.

Palatin recognized $250,000 in license and contract revenue for the fiscal year ended June 30, 2022, related to our license agreement with Fosun, compared to $94,689 for the quarter and fiscal year ended June 30, 2021, related to our license agreement with Kwangdong.

Total operating expenses were $13.9 million for the quarters ended June 30, 2022 and 2021.

Total operating expenses for the fiscal year ended June 30, 2022, were $38.1 million, compared to $33.2 million for the fiscal year ended June 30, 2021.

The increase in operating expenses was the result of increased research and development expenses primarily related to our ongoing pivotal Phase 3 clinical trial of PL9643, offset by decreased commercial expenses related to Vyleesi.

Total other income, net, consist mainly of unrealized foreign currency transaction gains and losses, which consisted of gains of $325,868 and $389,868, respectively, for the quarter and fiscal year ended June 30, 2022, compared to losses of $221,274 and $212,526, respectively, for the quarter and fiscal year ended June 30, 2021.

Palatin's net cash used in operations for the quarter and fiscal year ended June 30, 2022, was $7.7 million and $29.9 million, respectively, compared to net cash used in operations of $8.5 million and $22.6 million, respectively, for the same periods in 2021. The increase in net cash used in operations is mainly due to cash received in fiscal year ended June 30, 2021 related to our Termination Agreement with AMAG Pharmaceuticals offset by a one-time negotiated payment of approximately $7.0 million in the quarter ended December 31, 2020 related to inventory purchase commitments of Vyleesi and by increased operating expenses in fiscal year ended June 30, 2022.

Palatin's net loss for the quarter and fiscal year ended June 30, 2022, was $12.8 million and $36.2 million, or $(1.34) and $(3.79) per basic and diluted common share, respectively, compared to a net loss of $13.9 million and $33.6 million, or $(1.47) and $(3.55) per basic and diluted common share, respectively, for the same periods in 2021.

The decrease in net loss for the quarter ended June 30, 2022 over the quarter ended June 30, 2021, was mainly due to the increase of net product revenue of Vyleesi. The increase in net loss for the fiscal year ended June 30, 2022 over the fiscal year ended June 30, 2021, was mainly due to increased operating expenses offset by increased Vyleesi total revenues.

As of June 30, 2022, Palatin's cash and cash equivalents were $29.9 million with $1.8 million of accounts receivable, compared to cash and cash equivalents of $37.7 million with $0.8 million of accounts receivable as of March 31, 2022, and $60.1 million of cash and cash equivalents with $1.6 million of accounts receivable as of June 30, 2021.

The $29.9 million of cash and cash equivalents at June 30, 2022, does not include the $15 Million Private Placement of Redeemable Convertible Preferred Stock. These funds are being held in an escrow account, pending the investors' election to redeem the shares for cash or in notes, or convert the shares to common stock.

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.

Palatin is a biopharmaceutical company developing first-in-class medicines based on molecules that modulate the activity of the melanocortin receptor systems, with highly potent, 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.
