Dilution watch

Active shelf

Active shelf on file — the company can issue new shares on demand (valid ~3 years). If $ATER runs, these filings show who may be positioned to sell new or newly-registered shares into the move.

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.
