Warrants
| Tranche | Warrants | Exercise price | Term | Notes |
|---|---|---|---|---|
| Warrants7.75 | 185.4M | not tagged | — | FV $136.3M |
| Common Warrants | 185.4M | $2 | — | — |

| Prefunded Warrants | 138.9M | not tagged | — | — |
Tranches exactly as the company dimensioned them in its 10-Q filed Aug 10, 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: 5.3M underlying shares, as reported Dec 31, 2017 (10-K).
Reported exercise price: $2.1231 (aggregate figure as tagged; individual tranches vary).
Balance-sheet fair value of warrants: $136.3M as of Jun 30, 2026.
Rough fully diluted estimate: 1.40B = 1.40B O/S + 5.3M 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 |
|---|---|---|---|---|---|
| Convertible Senior Notes 6.75 Percent | $431.3M | — | not tagged | 6.75% | — |
Notes exactly as the company dimensioned them in its 10-Q filed Aug 10, 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 outstanding | 1.40B | Aug 6, 2026 |
| + Warrants7.75 (if exercised) | 185.4M | Oct 8, 2025 |

| Fully diluted estimate | 2.06B | +47.5% 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.
