CIK 1285819 · all EDGAR filings →

Overall dilution risk
HIGHworst of 4 computed signals (offering ability)
= the worst band among the computed sub-ratings, no hidden weighting
Offering ability
HIGHS-3ASR on file 2025-11-14
= 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
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+15% O/S in 3y
= share count now vs 3 years ago (bands: 30% / 100%); a reverse split pushes this negative
Cash need
MEDIUM~13.6 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.

Warrants

Warrants outstanding: 0 underlying shares, as reported Jun 30, 2023 (10-Q).

Reported exercise price: $23 (aggregate figure as tagged; individual tranches vary).

Balance-sheet fair value of warrants: $1.4M as of Apr 30, 2018.

Rough fully diluted estimate: 72.4M = 72.4M O/S + 0 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
the 2029 Notesnot tagged$42.0M$6.189.5%
Convertible Senior Notes 2026not tagged$0not tagged5.25%

Notes exactly as the company dimensioned them in its 10-Q filed Aug 12, 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 outstanding72.4MAug 7, 2026
+ Warrants (aggregate, as tagged) (if exercised)0Jun 30, 2023
Fully diluted estimate72.4M+0.0% 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.
