Mark D. Griffin

Mark D. Griffin, listed as chief executive, appears in our data through filings on Telos Corp shares, published by SEC (Form 4). In total, 16 filings cover trades dated from 21 January 2022 to 18 March 2026.

Purchases make up the whole of the open-market record (3 purchases, €68k). A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Besides market trades, the filings include 13 share grants.

Half of the purchases are above €24k and half below. Of 3 purchases, 3 formed part of a group of insiders buying within 30 days of each other. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.

The newest entry dates from 20 March 2026: a share grant, in Telos Corp. The most recent open-market purchase was published on 14 August 2024, 795 days ago. 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.
