Valuation, from the filing

Public float$632.56MMarket value of stock held by non-affiliates, as stated on the cover page for 2025-06-30
Float per share$13.94Float divided by shares outstanding in the same filing. A floor under the share price on that date, not the price itself.
Float / net income6.4×A lower bound on the multiple, because affiliate holdings are excluded.
Float / revenue0.9×A lower bound on the multiple, because affiliate holdings are excluded.
Float / equity0.8×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.

Valuation over time

6.4× earnings today, against a median of 10.8× across 9 years on record. Below its own history.

Each float is paired with the fiscal year the filing that stated it covers. Only years where the company reported positive net income appear, because a multiple against a loss is not a multiple.
