Brian Gephart: trading record in brief

Brian Gephart (senior executive) discloses dealings in 2 companies, chiefly Magnite, Inc. and Leaf Group Ltd. Between 1 May 2021 and 1 October 2026, the trades on record add up to 32 filings.

Every open-market trade on record is a sale: 9 sales worth €1.4M. Besides market trades, the filings include 22 share grants. In 2026 alone, the filings show no purchases and 1 sale.

The newest entry dates from 2 October 2026: a share grant, in Magnite, 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. 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.
