Third Quarter 2023 Financial Results

As of September 30, 2023 and December 31, 2022, the company had cash, cash equivalents and marketable securities totaling $324.4 million and $279.4 million, respectively. The increase was due to $107.4 million of net proceeds received from the issuance of common stock in an underwritten public offering.

Research and development expenses for the third quarter 2023 were $27.3 million, compared to $13.3 million for the third quarter 2022. The increase was primarily due to increased activities for the development of HIL-214 and the growth in the number of R&D employees.

General and administrative expenses for the third quarter 2023 were $6.6 million, compared to $4.6 million for the third quarter 2022. The increase was primarily due to the growth in the number of G&A employees.

Other income for the third quarter 2023 was $2.1 million, compared to $1.1 million for the third quarter 2022. The increase in other income in the third quarter of 2023 compared to the third quarter of 2022 was primarily driven by higher interest rates increasing interest income on the company’s cash, cash equivalents and marketable securities.

Net loss for the third quarter 2023 was $31.8 million, compared to $16.8 million for the third quarter 2022.
