Patrick V.J.J. Vink

Patrick V.J.J. Vink is a declared insider of Spero Therapeutics, Inc., with filings sourced from SEC (Form 4). In total, 4 filings cover trades dated from 15 September 2022 to 12 June 2025.

The filings describe grants, exercises and other transfers rather than trades on the open market. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.

On 16 June 2025 came the latest disclosure, a share grant in Spero Therapeutics, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 4 days. The legal deadline for a Form 4 is two business days after the transaction. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
