Overall dilution risk
HIGHworst of 4 computed sub-ratings (offering ability)
= the worst band among the computed sub-ratings, no hidden weighting
Offering ability
HIGHS-3ASR on file 2026-07-02
= is there a registration (S-1/S-3 family) on file without a later withdrawal
no structured fee data on the live registrations, so this is a yes/no, not a size
Overhead supply
MEDIUMwarrants = 22% 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+83% O/S in 3y
= share count now vs 3 years ago (bands: 30% / 100%); a reverse split pushes this negative
a reverse-split-sized cliff is in this window; read the chart
Cash need
LOW~78.4 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.

Share count fell from 386.3M to 38.8M between Mar 23, 2023 and May 10, 2023, a pattern consistent with a reverse split (roughly 1-for-10); simultaneous issuance can skew the raw ratio, so confirm in the filings. The red bar marks the cliff.

Warrants

Tranches exactly as the company dimensioned them in its 10-Q filed Aug 6, 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.

Warrants outstanding: 16.0M underlying shares, as reported Jun 30, 2021 (10-Q).

Balance-sheet fair value of warrants: $180,000 as of Dec 31, 2022.

Rough fully diluted estimate: 88.1M = 72.1M O/S + 16.0M 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.

Shares outstanding72.1MJul 31, 2026
+ Amazon Warrant (if exercised)3.3MJun 30, 2026
Fully diluted estimate75.4M+4.6% 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.
