Joseph D. Samberg

Joseph D. Samberg discloses dealings in 2 companies, chiefly Nextnav Inc. and NII Holdings Inc. Over a trading history stretching from 8 January 2018 to 21 November 2025, the count stands at 22 filings.

The open-market side counts 17 purchases for €6.9M alongside 4 sales for €18.0M. The net balance comes to €11.1M on the selling side. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Since January 2025: 1 purchase and 2 sales on the market.

The median purchase comes to €532k. Of 16 purchases, 4 formed part of a group of insiders buying within 30 days of each other. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

The newest entry dates from 24 November 2025: an open-market purchase of €601k, in Nextnav Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 3 days. The legal deadline for a Form 4 is two business days after the transaction. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
