Granite Ridge Resources, Inc.
A Dallas-based oil and natural gas explorer that takes a partner's seat rather than running its own rigs — it invests in wells across six major U.S. basins by teaming up with proven drillers and owning a stake in their projects. The company was born in 2022, when the private-equity firm Grey Rock Investment Partners merged with a special-purpose acquisition company, Executive Network Partnering Corporation, to go public on the New York Stock Exchange. The name nods to its roots: Granite Ridge rose from Grey Rock, an apt geological twist for an energy firm.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 3 years: -7.50M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
