A maker of plug-and-play fiber broadband gear, Clearfield builds the enclosures, optical components, and access terminals that bring high-speed internet to homes, businesses, and cell sites across North America. Its roots reach back to 1979, when it began as an optics firm called APA; in 2008 it rebranded as Clearfield to focus on fiber, a name its then-CEO said was chosen to signal designs that are creative yet practical and craft-friendly. Its FieldSmart, WaveSmart, and FieldShield products are the quiet hardware behind many fiber networks.
Select a row to see that insider’s individual transactions. † Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 5 years: -142.7K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
