A maker of software that helps manufacturers design, build, and service their products, PTC's tools include Creo for 3D design, Windchill for managing a product's lifecycle, and ThingWorx for internet-connected machines. Founded in 1985 by mathematician Samuel Geisberg, the company took the name Parametric Technology Corporation for its breakthrough 'parametric' modeling, which lets engineers change one dimension and update the whole design. Its 1988 launch of Pro/ENGINEER was the first commercially successful software of its kind, and the firm shortened its name to PTC in 2013.
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: -67.0K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
