Mark Frichtl

Mark Frichtl, listed as senior executive, appears in our data through filings on Ouster, Inc. shares, published by SEC (Form 4). We count 41 filings; the first trade dates from 20 March 2023 and the latest from 14 September 2026.

Market trades split into 4 purchases (€409k) and 22 sales (€19.9M). No amount is published for 1 filing, which the totals therefore leave out. Unlike grants, an open-market purchase is paid for by the insider, at the market price. The rest of the record consists of 4 share grants and 10 option exercises. 2026 to date brings no purchases and 20 sales.

Half of the purchases are above €114k and half below. Clusters matter here: 4 out of 4 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.

On 16 September 2026 came the latest disclosure, an open-market sale for €550k in Ouster, Inc. The most recent open-market purchase was published on 16 December 2024, 671 days ago. Typically, a trade is published a median of 2 days after it takes place. 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. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
