Insider transactions sourced from SEC EDGAR Form 4 filings, normalized within minutes of acceptance. "Buy"/"Sell" mark open-market transactions (codes P/S), the tradeable signal. Awards, option exercises and tax-withholding are shown with their raw code. All data is public domain.
Issuer: Summit Midstream Corp, SEC CIK 0002024218. The symbol on a Form 4 is typed by the filer, so this page follows the issuer with the newest filing under SMC and shows every filing by that issuer. Earlier filings under the same symbol by another issuer are left out.
Coverage: Form 4 filings indexed 2006-01-02 → 2026-09-15. Earlier history is backfilling; this window widens as it deepens.
Programmatic access via the Arkolith API & MCP server (insider.transactions, insider.company).
