Vincent Capponi

Vincent Capponi (chief executive) discloses dealings in Cytosorbents Corp to SEC (Form 4). Between 7 June 2016 and 14 September 2026, the trades on record add up to 58 filings.

In open-market terms, that means 7 purchases worth €55k on one side and 14 sales worth €1.1M on the other. The net balance comes to €1.1M on the selling side. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Other entries cover 16 share grants and 20 option exercises. Since January 2026: 2 purchases and no sales on the market.

Half of the purchases are above €5,689 and half below. Relative to company size, the median is 0.024% of market cap (4 purchases with a known value). 7 out of 7 purchases came within 30 days of a purchase by at least one other insider of the same company. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.

On 16 September 2026 came the latest disclosure, an open-market purchase for €9,426 in Cytosorbents Corp. Typically, a trade is published a median of 2 days after it takes place. US insiders must file a Form 4 within two business days of a trade. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
