First Quarter 2022 Financial Results

Cash, cash equivalents, and total investments as of March 31, 2022 totaled $132.7 million compared to $106.1 million on December 31, 2021. In April 2022, Eiger received $20.8 million in additional net proceeds from the sale of common stock under the Company's at-the-market facility, resulting in pro forma cash, cash equivalents and investments of $153.5 million, which is expected to fund planned operations into Q4 2024.

Net product sales of Zokinvy were $2.7 million for first quarter 2022, as compared to $3.6 million for first quarter 2021. The decrease was primarily driven by initial inventory build at the specialty pharmacy when Zokinvy was launched in the U.S. in January 2021.  

Cost of sales was approximately $0.1 million for first quarter 2022, as compared to $53,000 for the same period in 2021. The increase was primarily driven by product manufacturing related costs, including product testing.

Research and Development expenses were $17.5 million for first quarter 2022, as compared to $13.8 million for the same period in 2021. The increase is primarily driven by a $5.0 million milestone to BMS expensed in the quarter related to the LIMT-2 Phase 3 study of peginterferon lambda for HDV and an increase in personnel related costs, including stock-based compensation, from increased headcount. This increase was partially offset by lower clinical trial related costs, including contract manufacturing expenditures.

Selling, General and Administrative expenses were $6.8 million for first quarter 2022, as compared to $5.5 million for the same period in 2021. The increase was primarily due to an increase in personnel related expenses attributed to an increase in headcount and an increase in outside services, including consulting and advisory services to support the growth of the Company.

Total operating expenses include non-cash expenses of $2.8 million first quarter 2022, as compared to $2.2 million for the same period in 2021.

The Company reported a net loss of $22.6 million, or $0.64 per share for first quarter 2022. This compares to net income of $29.2 million, or $0.85 on a fully diluted per share basis for the same period in 2021 which included a one-time gain of $46.5 million related to the sale of a priority review voucher.

As of March 31, 2022, the company had 40.5 million of common shares outstanding.
