Recent Form-4 filings via Nasdaq. Open-market buys are the signal worth watching. Grants and automatic (10b5-1) sells are routine. “% of position” is the share of that insider’s own holding the trade moved. Not investment advice.
Dilution watch
Recent offeringRecent priced share offering — a one-time sale that has already completed (not ongoing). If $MGTX runs, these filings show who may be positioned to sell new or newly-registered shares into the move.
- 11,111,111 new shares · Priced at $9/share
Sourced from SEC EDGAR filings (last 9 months); terms read straight from the filing text where available. Ongoing = an at-the-market (ATM) program still selling over time or a live shelf, so it can keep diluting; Completed = a one-time priced sale that already finished. A shelf (S-3) stays effective ~3 years. Form type signals dilution capacity, not an exact share count, and we can't confirm how much of a shelf or ATM remains unused. Not investment advice.
