Avi S. Katz

Avi S. Katz is a declared insider at 8 companies (board member); the most frequent names are GigOptix, Inc., Kaleyra, Inc. and BigBear.ai Holdings, Inc. The record holds 162 filings, for trades running from 1 February 2016 to 2 September 2026.

The open-market side counts 12 purchases for €16.9M alongside 40 sales for €12.2M. The totals do not cover 1 filing with an undisclosed amount. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Outside the open market, there are 51 share grants and 29 option exercises. 2026 to date brings 1 purchase and no sales.

Half of the purchases are above €565k and half below. Of 10 purchases, 3 formed part of a group of insiders buying within 30 days of each other. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time.

The latest filing, published on 4 September 2026, reports a share grant of €1.1M in Hadron Energy, Inc. The latest purchase dates back some time: it was published 273 days ago, on 23 January 2026. Typically, a trade is published a median of 2 days after it takes place. For comparison, the SEC allows two business days to file a Form 4. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. These figures are compiled from regulatory filings published by SEC (Form 4).
