Fourth Quarter and Full Year 2022 Financial Results

Net revenue was $2.7 million and $13.5 million in fourth quarter and full year 2022, respectively, as compared to $3.4 million and $12.1 million for the same periods in 2021. The decrease in fourth quarter was primarily driven by a decrease in units shipped during the quarter and the increase in full year 2022 was primarily driven by the upfront payment received from AnGes, Inc. pursuant to the Marketing and Distribution Agreement, which was executed in May 2022.

Cost of sales was $0.3 million and $1.8 million for fourth quarter and full year 2022, respectively, as compared to $0.1 million and $0.7 million for the same periods in 2021. The increase in fourth quarter was primarily driven by a minimum purchase commitment by our contract manufacturer. The increase in full year was primarily driven by a one-time write-off of a non-conforming batch of inventory.

Research and Development expenses were $18.5 million and $75.3 million for fourth quarter and full year 2022, respectively, as compared to $18.2 million and $64.4 million for the same periods in 2021. Net change in the fourth quarter was relatively flat. The increase in full year was primarily driven by an increase in headcount related expenses, including stock-based compensation expense and travel expenses related to participation in scientific conferences, an increase in clinical and manufacturing expenditures related to avexitide Phase 3 readiness, and a milestone related to the Phase 3 LIMT-2 study of peginterferon lambda. This increase was primarily offset by a decrease in contract manufacturing expenditures on lonafarnib.

Selling, General and Administrative expenses were $8.3 million and $29.1 million for fourth quarter and full year 2022, respectively, as compared to $6.0 million and $23.9 million for the same periods in 2021. The increase in fourth quarter and full year primarily relate to outside services, including consulting and advisory services to support the Company’s growth.

Total operating expenses include non-cash expenses of $2.4 million and $13.3 million for fourth quarter and full year 2022, respectively, as compared to $2.8 million and $10.7 million for the same periods in 2021.

The Company reported a net loss of $25.1 million, or $0.57 per share basis and $96.8 million, or $2.32 per share basis for fourth quarter and full year 2022, respectively. This compares to a net loss of $21.8 million, or $0.64 per share basis and $33.9 million, or $1.00 per share basis for the same periods in 2021.

Cash, cash equivalents, and short-term debt securities as of December 31, 2022 totaled $98.9 million compared to $106.1 million as of December 31, 2021.
