Filings by Timothy A. Springer span 3 companies, the busiest being Cartesian Therapeutics, Inc., Morphic Holding, Inc. and Tectonic Therapeutic, Inc. In total, 36 filings cover trades dated from 21 May 2021 to 2 January 2026.

Every open-market trade on record is a purchase: 22 purchases worth €91.7M, and no sale. The totals do not cover 1 filing with an undisclosed amount. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. The rest of the record consists of 7 share grants and 3 option exercises.

In size, the median ticket on the buying side is €560k. Clusters matter here: 5 out of 22 purchases overlapped with buying by a colleague within 30 days. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time.

Most recently, on 6 January 2026, the filings show a share grant in Cartesian Therapeutics, Inc. The most recent open-market purchase was published on 11 April 2025, 555 days ago. Typically, a trade is published a median of 2 days after it takes place. For comparison, the SEC allows two business days to file a Form 4. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
