Gregg Williams

All filings by Gregg Williams on record concern Vivani Medical, Inc., in the capacity of board member. The record holds 57 filings, for trades running from 8 February 2016 to 15 July 2026.

The open-market record is one-sided, with 54 purchases worth €25.4M and not one sale. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. 2026 to date brings 6 purchases and no sales.

In size, the median ticket on the buying side is €7,085. On 26 out of 54 purchases, another insider of the same company was buying within the same 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.

Most recently, on 16 July 2026, the filings show an open-market purchase worth €874k in Vivani Medical, Inc. The median gap between a trade and its publication by SEC (Form 4) is 2 days. For comparison, the SEC allows two business days to file a Form 4. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
