Jeffrey S. Bornstein

Filings by Jeffrey S. Bornstein span 3 companies, the busiest being Eos Energy Enterprises, Inc., General Electric Co and Kalaris Therapeutics, Inc. In total, 15 filings cover trades dated from 3 February 2016 to 21 July 2026.

Market trades split into 3 purchases (€87k) and 5 sales (€733k). The amount is not disclosed for 3 filings. 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 2 share grants and 5 option exercises.

The median purchase comes to €26k. Clusters matter here: 1 out of 3 purchases overlapped with buying by a colleague within 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

The record was last updated on 6 August 2026 with an option exercise (€46k) in Eos Energy Enterprises, Inc. The latest purchase dates back some time: it was published 1,434 days ago, on 14 November 2022. Typically, a trade is published a median of 2 days after it takes place. The legal deadline for a Form 4 is two business days after the transaction. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
