Dilution profile // every instrument, one screen, from SEC filings

Overall dilution risk
HIGHworst of 3 computed sub-ratings (offering ability)
= the worst band among the computed sub-ratings, no hidden weighting
not every sub-rating was computable; treat as a floor
Offering ability
HIGH$200M registered
= total registered offering amount from the fee exhibits of live registrations (bands: $1M / $20M)
one or more live registrations had no structured fee data, so the true total is AT LEAST this
Overhead supply
NOT COMPUTEDno warrant count tagged in XBRL
= warrant shares outstanding divided by current shares outstanding
absence of a tag is not proof of absence of warrants
Historical dilution
HIGH+405% O/S in 3y
= share count now vs 3 years ago (bands: 30% / 100%); a reverse split pushes this negative
Cash need
LOW~58.7 months of runway
= cash vs trailing operating burn (bands: 6mo / 24mo; positive operating CF = low)

Same rating bands the category standard uses, but free, with the formula on the chip and the gaps in the data said out loud.

Tranches exactly as the company dimensioned them in its 10-Q filed Aug 11, 2026 →. Groupings can overlap (a “Series E and F” row is not additive with a “Series E” row), so do not sum this column. A tranche the filer did not tag is absent here, not absent from the cap table. DOWN-ROUND = the filer tagged price-protection accounting scoped to that tranche.

Balance-sheet fair value of warrants: $0 as of Dec 31, 2025.

Convertible notes

No convertible-note facts tagged in the 10-Q filed Aug 11, 2026. If convertible notes exist, their terms live in exhibit prose for this filer and are not parsed; absence of a tag is not proof of absence. The exhibits are the ground truth.

Fully diluted build-up

Shares outstanding plus every potential-share instrument the filer tagged in XBRL, each at its own as-of date. An estimate assembled from filed figures, not a filing figure itself.

Still excluded, because the filer does not tag them in countable form: employee options and RSUs, any instrument living only in exhibit prose, and instruments above missing a share count. Inputs carry different as-of dates, shown per row. Each figure traces to the tranche and note tables above and their cited filings.

Source: SEC EDGAR XBRL company facts and filing metadata, fetched live and cached briefly. Share counts are cover-page figures with their form named. Warrant tranches and convertible notes come from the dimensioned facts in the latest 10-Q/10-K instance document, exactly as the company tagged them; untagged tranches and notes are absent, not disproven. Nothing on this page is manually verified and nothing is behind a login: what free data supports is shown, what it cannot support is stated. Not investment advice.
