Analysis · CELC · Industrial Applications And Services
On July 14, 2026—the very day the FDA approved Celcuity's first drug—Baker Bros. Advisors, a prominent biotech hedge fund, sold 3.1 million shares at $102.50 apiece. The transaction generated roughly $317.8 million in proceeds and trimmed the fund's beneficial ownership from above 10% to exactly 9.99%, prompting a switch from active Schedule 13D to passive Schedule 13G reporting. Selling into the approval pop suggests profit-taking rather than a negative fundamental view, yet the size of the sale and the shift to passive status remove a key institutional backstop. Baker Bros. still retains 4.8 million common shares, 6.1 million prefunded warrants, and $30.75 million in convertible notes, but a 9.99% cap on warrant exercise and a 4.99% blocker on the notes limit near-term conversion. For a newly commercial-stage biotech, this marks a material change in the ownership structure.
