Overall dilution risk
HIGHworst of 4 computed signals (offering ability)
= the worst band among the computed sub-ratings, no hidden weighting
Offering ability
HIGH$570M registered
= total registered offering amount from the fee exhibits of live registrations (bands: $1M / $20M)
registered capacity, not remaining: amounts already taken down are not subtracted yet
Overhead supply
LOWwarrants = 3% of O/S
= warrant shares outstanding divided by current shares outstanding (bands: 20% / 50%)
warrants only; converts, ATMs and equity lines are not in free structured data, so the true overhead is AT LEAST this
Historical dilution
MEDIUM+51% O/S in 3y
= share count now vs 3 years ago (bands: 30% / 100%); a reverse split pushes this negative
Cash need
LOW~40 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.

Warrants

Warrants outstanding: 2.9M underlying shares, as reported Jun 30, 2026 (10-Q).

Reported exercise price: $0.0001 (aggregate figure as tagged; individual tranches vary).

Rough fully diluted estimate: 99.8M = 96.8M O/S + 2.9M warrant shares. An estimate, not a filing figure: it ignores converts, options and RSUs, and the two inputs carry different as-of dates.

Convertible notes

No convertible-note facts tagged in the 10-Q filed Aug 6, 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.

+ Warrants (aggregate, as tagged) (if exercised)2.9MJun 30, 2026
Fully diluted estimate99.8M+3.0% vs O/S

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.
