Brent Pfeiffenberger

Brent Pfeiffenberger discloses dealings in 3 companies, chiefly Century Therapeutics, Inc., Butterfly Network, Inc. and Corbus Pharmaceuticals Holdings, Inc. In total, 24 filings cover trades dated from 4 December 2023 to 11 September 2026.

The open-market side counts 2 purchases for €41k alongside 6 sales for €55k. Sales outweigh purchases by €14k. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The rest of the record consists of 16 share grants.

On 15 September 2026 came the latest disclosure, a share grant for €23k in Century Therapeutics, Inc. The last purchase on record was published on 16 December 2025, which is 309 days ago. Filings reach the SEC (Form 4) feed a median of 3 days after the trade. Section 16 rules allow two business days to file each Form 4. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
