Pdf Solutions Inc
A maker of software and analytics tools for the semiconductor industry, PDF Solutions doesn't build chips itself but supplies the data platforms—brands like Exensio, Sapience, and Cimetrix—that connect fabrication equipment, analyze manufacturing data, and help chipmakers improve production yield. It was founded in 1991 by two engineers, and despite its name, "PDF" stands for "Product Design for Manufacturing"—not the Portable Document Format file type it's often mistaken for.

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: -2.55M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
