4D Molecular sees cash runway into 2H28

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.
