Richard K. Stoneburner: trading record in brief
Richard K. Stoneburner, listed as board member, has filed trades across 3 companies (mainly through SEC (Form 4)), most often in Tamboran Resources Corp, Sitio Royalties Corp. and Brigham Minerals, Inc. In total, 15 filings cover trades dated from 26 May 2021 to 15 April 2026.
The open-market record is one-sided, with 2 purchases worth €377k and not one sale. 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 11 share grants.
On 16 April 2026 came the latest disclosure, a share grant for €249k in Tamboran Resources Corp. The most recent open-market purchase was published on 8 July 2024, 832 days ago. Filings reach the SEC (Form 4) feed a median of 3 days after the trade. US insiders must file a Form 4 within two business days of a trade. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
