Idexx Laboratories Inc /de
A maker of diagnostic tests and software for veterinarians, from point-of-care analyzers like Catalyst One and SNAP rapid tests to practice software such as ezyVet and Cornerstone. It also sells water-testing kits like Colilert, used by labs and utilities to spot E. coli, plus tests for livestock diseases and antibiotic residues in milk. Founded in 1983 in Maine as AgriTech Systems, it later renamed itself IDEXX after "Idx," clinical shorthand for immunochemical diagnostics.

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 year: -55.4K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
