Waters Corporation
A maker of analytical instruments that help scientists separate, identify, and measure chemicals, Waters Corporation builds liquid chromatography and mass spectrometry systems (like ACQUITY UPLC and Xevo) used by pharmaceutical, industrial, and academic labs, plus thermal analysis tools under its TA Instruments brand. Founded in 1958 by James Waters, the company began as a five-person "research boutique" in the basement of the Framingham, Massachusetts police station, building custom instruments like nerve gas detectors before becoming a leader in chromatography.

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 all recorded history: -5.28M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
