Overall dilution risk
HIGHworst of 4 computed signals (offering ability)
= the worst band among the computed sub-ratings, no hidden weighting
Offering ability
HIGH$259M 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 = 2% 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-59% 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 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

2020-07-312026-08-06

Latest: 39.4M shares as of Aug 6, 2026 (10-Q). Share count fell from 95.8M to 4.8M between Jun 25, 2024 and Aug 13, 2024, a pattern consistent with a reverse split (roughly 1-for-20); simultaneous issuance can skew the raw ratio, so confirm in the filings. The red bar marks the cliff.

Warrants

Term Loan Warrantnot tagged$20
Conversion Warrant Liabilitiesnot taggednot taggedFV $1.3M

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.

Warrants outstanding: 678,000 underlying shares, as reported Dec 31, 2024 (10-Q).

Reported exercise price: $1.33 (aggregate figure as tagged; individual tranches vary).

Balance-sheet fair value of warrants: $31.7M as of Jun 30, 2026.

Down-round (price protection) accounting has been tagged in this filer’s XBRL: some instrument carries repricing protection. Which tranche requires reading the exhibits.

Rough fully diluted estimate: 40.1M = 39.4M O/S + 678,000 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
Convertible Debtnot tagged$5.19410%

Notes exactly as the company dimensioned them in its 10-Q filed Aug 11, 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.

Fully diluted estimate42.2M+7.1% 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.
