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: Nano Nuclear Energy Inc., SEC CIK 0001923891. The symbol on a Form 4 is typed by the filer, so this page follows the issuer with the newest filing under NNE and shows every filing by that issuer.
Coverage: Form 4 filings indexed 2006-01-02 → 2026-09-14. Earlier history is backfilling; this window widens as it deepens.
