Overall dilution risk
HIGHworst of 4 computed signals (offering ability)
= the worst band among the computed sub-ratings, no hidden weighting
Offering ability
HIGH$175M 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
LOWwarrants = 0% 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
LOW+27% 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
MEDIUM~9 months of runway
= cash vs trailing operating burn (bands: 6mo / 24mo; positive operating CF = low)
the company itself flagged going-concern doubt

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

Shares outstanding over time

2020-10-292026-08-05

Latest: 189.9M shares as of Aug 5, 2026 (10-Q). Share count fell from 313.6M to 23.7M between Oct 31, 2013 and Feb 28, 2014, a pattern consistent with a reverse split (roughly 1-for-13); simultaneous issuance can skew the raw ratio, so confirm in the filings. The red bar marks the cliff.

Warrants

Warrants outstanding: 220,164 underlying shares, as reported Dec 31, 2020 (10-K).

Rough fully diluted estimate: 190.1M = 189.9M O/S + 220,164 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

NotePrincipalCarryingConv. priceRateIf converted
Two Thousand Thirty One Senior Unsecured Convertible Notes$35.0M$35.0M$555.55565%~63,000 sh
Two Thousand Twenty Six Senior Unsecured Convertible Notesnot tagged$0not tagged

If every note above converted at its tagged price: ~63,000 new shares on 189.9M currently outstanding. An estimate from principal ÷ conversion price, with inputs carrying different as-of dates; make-whole adjustments, capped calls and partial repurchases are not modeled.

Notes exactly as the company dimensioned them in its 10-Q filed Aug 10, 2026. Principal is face amount as tagged, not what remains after repurchases unless the filer updated the tag. A note the filer did not dimension is absent here, not absent from the balance sheet; the exhibits stay 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 outstanding189.9MAug 5, 2026

+ Two Thousand Thirty One Senior Unsecured Convertible Notes (if fully converted)63,000Jun 30, 2026
Fully diluted estimate190.1M+0.1% 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.
