Dilution watch
Active shelfRecent share offering + active shelf on file — the company raised capital and can raise more. If $RUBI runs, these filings show who may be positioned to sell new or newly-registered shares into the move.
Sourced from SEC EDGAR filings. Offering terms are read straight from the filing text where available. We flag by form type and recency (last 9 months): a shelf (S-3) stays active for ~3 years and lets the company issue on demand, while a priced 424B offering is a one-time, completed event. Form type signals dilution capacity, not an exact share count, and we do not confirm how much of a shelf remains unused. Not investment advice.
