Overall dilution risk
HIGHworst of 4 computed signals (offering ability)
= the worst band among the computed sub-ratings, no hidden weighting
Offering ability
HIGH$346M 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 = 4% 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+22% O/S in 3y
= share count now vs 3 years ago (bands: 30% / 100%); a reverse split pushes this negative
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.

Tranches exactly as the company dimensioned them in its 10-Q filed Aug 7, 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: 3.5M underlying shares, as reported Jun 30, 2026 (10-Q).

Balance-sheet fair value of warrants: $64.2M as of Dec 31, 2024.

Rough fully diluted estimate: 102.7M = 99.2M O/S + 3.5M 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 Loan$5.0M$169.5%~312,500 sh

If every note above converted at its tagged price: ~312,500 new shares on 99.2M 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 7, 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 estimate116.5M+17.4% 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.

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.
