First Quarter 2023 Financial Results

Product revenue, net was $4.1 million for the first quarter of 2023, as compared to $2.7 million for the same period in 2022. The increase in product revenue was primarily due to higher sales in Germany, France ATU, and U.S during the quarter.

Cost of sales was flat for the three months ended March 31, 2023 compared to the same period in 2022.

Research and Development expenses was $16.7 million for the first quarter of 2023, as compared to $17.6 million for the same period in 2022. The decrease was primarily driven by a decrease in milestone expense related to the Phase 3 LIMT-2 study of peginterferon lambda for HDV under the BMS License Agreement, which occurred in March 2022, and a decrease in outside services across programs including consulting and advisory services. These decreases were partially offset by an increase in clinical and contract manufacturing expenditures, an increase in headcount related expenses, including stock-based compensation, and an increase in operational overhead costs.

Selling, General and Administrative expenses was $9.5 million for the first quarter of 2023, as compared to $6.8 million for the same period in 2022. The increase primarily relates to an increase in outside services, including consulting, advisory and accounting services, an increase in compensation and personnel related expenses, including stock-based compensation, and an increase in other operating expenses, all to support Company operations.

Total operating expenses include non-cash expenses of $2.7 million for the first quarter of 2023, as compared to $2.8 million for the same period in 2022.

The Company reported a net loss of $22.8 million, or $0.52 per share basis for the first quarter of 2023. This compares to a net loss of $22.6 million, or $0.64 per share basis for the same period in 2022.
