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
Latest: 33.0M shares as of Aug 6, 2026 (10-Q). Share count fell from 176.8M to 11.9M between Aug 9, 2024 and Nov 8, 2024, a pattern consistent with a reverse split (roughly 1-for-15); simultaneous issuance can skew the raw ratio, so confirm in the filings. The red bar marks the cliff.

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: 5.2M underlying shares, as reported Jun 30, 2026 (10-Q).
Reported exercise price: $11.5 (aggregate figure as tagged; individual tranches vary).
Balance-sheet fair value of warrants: $0 as of Dec 31, 2021.
Rough fully diluted estimate: 38.2M = 33.0M O/S + 5.2M 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 11, 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.

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.
