Business Quant data shows HeartCore Enterprises insiders holding 651.63K shares in total in their latest Form 4 filings, or 45.20% of the 1.44Mn shares outstanding; that total is unchanged from the end of Q2 2026 and Q3 2025 (split-adjusted).

Each row is that insider’s most recently reported position, from Form 4 filings over the last 60 months — which is why this total does not tie to the quarterly series above, where a quarter counts only the insiders who filed in it. Shares held through a fund or institutional portfolio are counted on the institutional ownership page instead.
