Fiscal year ended 2025-12-31Valuation, from the filing
| Public float | $60.00M | Market value of stock held by non-affiliates, as stated on the cover page for 2025-06-30 |
|---|---|---|
| Float per share | $3.62 | Float divided by shares outstanding in the same filing. A floor under the share price on that date, not the price itself. |
| Float / revenue | 0.6× | A lower bound on the multiple, because affiliate holdings are excluded. |
Every figure here is drawn from the 10-K cover page and the statements behind it, so each one traces to a filing. Public float counts only stock held by non-affiliates, which makes these floors rather than estimates: a high multiple is conclusive, a low one may mean cheap or may mean closely held. The float was measured on 2025-06-30, not today, and each multiple below it uses the figures for the fiscal year ending 2025-12-31 — the year that filing covered.
