Valuation, from the filing

Public float$6.70MMarket value of stock held by non-affiliates, as stated on the cover page for 2024-06-30
Float per share$2.51Float divided by shares outstanding in the same filing. A floor under the share price on that date, not the price itself.
Float / revenue2.0×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 2024-06-30, not today, and each multiple below it uses the figures for the fiscal year ending 2024-12-31 — the year that filing covered.

How this compares in its industry

Percentile among the Miscellaneous Electrical Machinery, Equipment & Supplies 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.

Reconciliation checks needing review

4 periods on this page do not reconcile under this site’s normalization. Read that as a limitation here before an observation about the company: the figures are the filer’s own, the filings linked above are authoritative, and a difference usually means the concepts this site selected do not match how this filer presents its statements. Nothing is adjusted to make a check pass.
