Valuation, from the filing

Public float$97.87MMarket value of stock held by non-affiliates, as stated on the cover page for 2025-06-30
Float per share$1.03Float divided by shares outstanding in the same filing. A floor under the share price on that date, not the price itself.
Float / revenue1.9×A lower bound on the multiple, because affiliate holdings are excluded.
Float / equity2.7×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.

How this compares in its industry
