Q3 2025 Financial Results

Cash Position: Cash, cash equivalents and marketable securities were $372 million as of September 30, 2025, as compared to $505 million as of December 31, 2024. The net decrease in cash was primarily a result of cash used in operations. Based on our current operating plan, we estimate that our existing cash, cash equivalents and marketable securities, and expected payments under our collaboration agreement with Otsuka, together with the net proceeds from the November 2025 equity offering, will be sufficient to fund our operating expenses and capital expenditure requirements at least into the second half of 2028.

R&D Expenses: Research and development expenses were $49.4 million for the third quarter of 2025, as compared to $38.5 million for the third quarter of 2024. This increase was primarily driven by the Phase 3 clinical trials of 4D-150 in wet AMD.

G&A Expenses: General and administrative expenses were $11.8 million for the third quarter of 2025, as compared to $12.7 million for the third quarter of 2024. The decrease was primarily due to decreased headcount of general and administrative personnel.

Net Loss: Net loss was $56.9 million for the third quarter of 2025, as compared to net loss of $43.8 million for the third quarter of 2024.
