Overall dilution risk
HIGHworst of 3 computed signals (offering ability)
= the worst band among the computed sub-ratings, no hidden weighting
not every sub-rating was computable; treat as a floor
Offering ability
HIGHS-3ASR on file 2023-05-05
= 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
NOT COMPUTEDno warrant count tagged in XBRL
= warrant shares outstanding divided by current shares outstanding
absence of a tag is not proof of absence of warrants
Historical dilution
LOW+11% 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
LOWoperating cash flow positive
= 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

2020-10-272026-07-29

Latest: 83.5M shares as of Jul 29, 2026 (10-Q). Share count fell from 82.8M to 8.3M between Feb 18, 2026 and May 5, 2026, 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

No warrant figures tagged in this filer’s XBRL facts. That means the company has not reported them in structured form; it does not prove no warrants exist. The exhibits are the ground truth.

Convertible notes

Convertible Senior Notes 1.5 Due September 152026$287.5M$287.5M$52.521.5%~5.5M sh

If every note above converted at its tagged price: ~10.6M new shares on 83.5M 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 Jul 30, 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 outstanding83.5MJul 29, 2026

Fully diluted estimate94.1M+12.7% 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.
