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
| Note | Principal | Carrying | Conv. price | Rate | If converted |
|---|---|---|---|---|---|
| Two Point Five Zero Convertible Senior Notes Due 2032 | $30.0M | $230.0M | $26.5 | 2.5% | ~1.1M sh |
If every note above converted at its tagged price: ~1.1M new shares on 65.2M 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 13, 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 | 65.2M | Jul 31, 2026 |
| + Two Point Five Zero Convertible Senior Notes Due 2032 (if fully converted) | 1.1M | Apr 30, 2026 |
| Fully diluted estimate | 66.3M | +1.7% 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.
