Second Quarter 2023 Financial Results

Total revenue was $4.6 million for the second quarter of 2023, as compared to $4.1 million for the same period in 2022. The increase was primarily driven by  the product sales in Germany compared to no such sales for the same period in 2022. The increase was partially offset by a decrease of certain upfront payments received under the terms of the Marketing and Distribution Agreement (MDA) with AnGes, Inc., which was executed in May 2022, relating to obtaining regulatory approval for and commercialization of Zokinvy in Japan.

Cost of sales decreased by $0.5 million in the second quarter 2023 compared to the same period in 2022. The decrease was primarily due to a reversal of an inventory accrual related to a nonconforming batch of product. During the second quarter 2023, the Company was notified by the vendor that it was no longer obligated to pay for that nonconforming batch of product.

Research and development expenses were $19.4 million for the second quarter of 2023, as compared to $17.0 million for the same period in 2022. The increase was primarily due to an increase in clinical and contract manufacturing expenditures and an increase in compensation and personnel related expense. The increase was partially offset by a decrease in outside services across programs, including consulting and advisory services due to a decline in spending on peginterferon lambda programs.

Selling, general and administrative expenses were $5.5 million for the second quarter of 2023, as compared to $7.0 million for the same period in 2022. The decrease was primarily due to a decrease in compensation and personnel related expense, including stock-based compensation, and a decrease in outside services, including consulting, advisory and accounting services.

Total operating expenses include non-cash expenses of $0.9 million for the second quarter of 2023, as compared to $4.1 million for the same period in 2022. The decrease was primarily due to a change in amortization of premiums and discounts on debt securities due to current market and economic conditions, a decrease in loss on early extinguishment of Oxford loan paid off in June 2022 and a decrease in stock based compensation expenses.

The Company reported a net loss of $20.7 million, or $0.47 per share basis for the second quarter of 2023. This compares to a net loss of $21.9 million, or $0.51 per share basis for the same period in 2022.

Cash, cash equivalents, and short-term debt securities as of June 30, 2023 totaled $53.6 million, as compared to $98.9 million as of December 31, 2022.

As of June 30, 2023, the Company had 44,296,417 common shares outstanding.
