Third Quarter 2023 Financial Results

Total revenue was $3.2 million for the third quarter of 2023, as compared to $4.0 million for the same period in 2022. The decrease was primarily driven by a decrease in U.S. sales. It was partially offset by an increase in sales in France under the Company's Temporary Authorizations for Use for Zokinvy^®, compared to no such sales for the same period in 2022.

Cost of sales decreased by $1.1 million in the third quarter 2023 compared to the same period in 2022. The decrease was primarily due to a non-conforming batch of inventory that was written off during the three months ended September 30, 2022.

Research and development expenses were $14.6 million for the third quarter of 2023, as compared to $22.2 million for the same period in 2022. The decrease was primarily attributed to a decrease in clinical and contract manufacturing expenditures due to a decline in manufacturing costs for peginterferon lambda and avexitide, a decrease in compensation and personnel related expense due to a decrease in headcount, and a decrease in outside services across programs including consulting and advisory services due to a decline in spending on the Company's peginterferon lambda program.

Selling, general and administrative expenses were $5.5 million for the third 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 $1.4 million for the third quarter of 2023, as compared to $4.0 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 and a decrease in compensation and personnel related expense including stock-based compensation, due to a decrease in headcount.

The Company reported a net loss of $18.0 million, or $0.41 per share basis for the third quarter of 2023. This compares to a net loss of $27.1 million, or $0.62 per share basis for the same period in 2022.

Cash, cash equivalents, and short-term debt securities as of September 30, 2023 totaled $39.4 million, as compared to $98.9 million as of December 31, 2022.

As of September 30, 2023, the Company had 44,384,684 common shares outstanding.
