Third Quarter 2025 Financial Results

Cash, Cash Equivalents and Investments : As of September 30, 2025, cash, cash equivalents and investments totaled $596.4 million, as compared to $781.3 million as of December 31, 2024. The company expects its current cash, cash equivalents, and investments will be sufficient to fund its operating expenses and capital expenditure requirements into 2029.

R&D Expenses : Research and development expenses were $68.3 million for the third quarter of 2025, as compared to $76.6 million for the third quarter of 2024. The decrease of $8.4 million was primarily due to the series of strategic choices made to streamline the research organization throughout 2024 and 2025, as well as cost avoidance on continued development of lirafugratinib after execution of the license agreement with Elevar Therapeutics, Inc. in December 2024, offset by increases in costs for the ReDiscover-2 Trial and ReInspire Trial.

G&A Expenses : General and administrative expenses were $12.1 million for the third quarter of 2025, as compared to $19.8 million for the third quarter of 2024. The decrease of $7.6 million was primarily due to a decrease in stock compensation expense, as well as other employee compensation costs.

Net Loss : Net loss was $74.1 million for the third quarter of 2025, or a net loss per share of $0.43, as compared to a net loss of $88.1 million for the third quarter of 2024, or a net loss per share of $0.63.
