Overall dilution risk
HIGHworst of 4 computed signals (offering ability)
= the worst band among the computed sub-ratings, no hidden weighting
Offering ability
HIGH$300M 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
MEDIUM+72% 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
HIGH~3.1 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.

Shares outstanding over time

2020-11-062026-07-31

Latest: 98.1M shares as of Jul 31, 2026 (10-Q). Share count fell from 45.7M to 3.9M between May 10, 2019 and Aug 7, 2019, a pattern consistent with a reverse split (roughly 1-for-12); simultaneous issuance can skew the raw ratio, so confirm in the filings. The red bar marks the cliff.

Warrants

Warrants outstanding: 13,904 underlying shares, as reported Dec 31, 2020 (10-K).

Balance-sheet fair value of warrants: $242,000 as of Mar 31, 2015.

Rough fully diluted estimate: 98.1M = 98.1M O/S + 13,904 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 7, 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 outstanding98.1MJul 31, 2026
+ Warrants (aggregate, as tagged) (if exercised)13,904Dec 31, 2020
Fully diluted estimate98.1M+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.
