Eikon (EIKN) 10% Owner Foresite Capital Buys $1.0M Stock
What Happened
- Foresite Capital Management IV, LLC (reported as a 10% owner) reported multiple transactions on Feb 4, 2026. The filing shows an open‑market purchase of 55,555 shares at $18.00 each for $999,990. In addition, the filing lists numerous non‑cash "conversion of derivative security" entries: about 4,041,687 shares were reported as acquired via conversion and about 30,142,109 shares were reported as disposed via conversion (all at $0.00), for a net reported decrease of 26,044,867 shares.
- The $18 open‑market purchase is a straightforward cash buy (bullish signal for that specific line). The many zero‑price "C" entries are conversions of derivative securities (non‑cash) — see footnote F1 explaining prior preferred stock conversion mechanics — and do not reflect open‑market sales for cash.

Context
- These filings are from an institutional 10% owner (fund/GPS structure), not an individual executive; institutional conversions and internal transfers are common and can reflect fund mechanics rather than a trading view.
- "Conversion of derivative security" entries are non‑cash events (not open‑market sales or purchases). The one cash purchase (55,555 shares at $18) is the clearest direct buy signal in this filing.
- For full details (exact post‑transaction holdings and rationale), consult the complete Form 4 and related disclosures.
