Valuation, from the filing

Public float$299.50MMarket value of stock held by non-affiliates, as stated on the cover page for 2025-06-30
Float per share$1.71Float divided by shares outstanding in the same filing. A floor under the share price on that date, not the price itself.
Float / net income7.6×A lower bound on the multiple, because affiliate holdings are excluded.
Float / revenue0.4×A lower bound on the multiple, because affiliate holdings are excluded.
Float / equity0.7×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

Percentile among the Services-Computer Integrated Systems Design filers on this site, highest value first. A high percentile means a large figure, which is good for a margin and not for leverage — the ranking says where the company sits, not whether that is where it should be.
