Tranches exactly as the company dimensioned them in its 10-Q filed Nov 5, 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: 54.4M underlying shares, as reported Mar 31, 2024 (10-Q).
Reported exercise price: $11.5 (aggregate figure as tagged; individual tranches vary).
Balance-sheet fair value of warrants: $24.6M as of Mar 31, 2024.
Rough fully diluted estimate: 420.7M = 366.4M O/S + 54.4M 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
| Note | Principal | Carrying | Conv. price | Rate | If converted |
|---|---|---|---|---|---|
| 2025 Convertible Notes | not tagged | $600.0M | not tagged | — | — |
| 2025 Convertible Notes Due 2031 | $525.0M | $326.8M | $16.16 | 1.75% | ~32.5M sh |
| 2025 Convertible Notes Due 2030 | $225.0M | $48.3M | $5.06 | 6.75% | ~44.5M sh |
| 2021 Convertible Notes | $122.9M | — | not tagged | — | — |
| AFG Convertible Notes | $13.8M | — | $1.67 | 7%-26.5% | ~8.2M sh |
If every note above converted at its tagged price: ~85.2M new shares on 366.4M 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 Nov 5, 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.

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.
