Q2 2026 Financial Results

Cash Position: Cash, cash equivalents and marketable securities were $430.6 million as of June 30, 2026, as compared to $514.0 million as of December 31, 2025. 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, will be sufficient to fund our operating expenses and capital expenditure requirements at least into the second half of 2028.   

Collaboration and License Revenue: Collaboration and license revenue was $3.8 million for the second quarter of 2026, as compared to an insignificant amount for the second quarter of 2025. The increase in revenue was primarily due to the clinical trial cost sharing and reimbursement?amounts from Otsuka.?

R&D Expenses: Research and development expenses were $68.3 million for the second quarter of 2026, as compared to $48.0 million for the second quarter of 2025. This increase was primarily driven by execution of 4D-150 Phase 3 clinical trials in wet AMD.

G&A Expenses: General and administrative expenses were $12.5 million for the second quarter of 2026, as compared to $11.5 million for the second quarter of 2025.
