Merit Medical Systems Inc
A maker of single-use medical devices for cardiology, radiology, oncology, and endoscopy, Merit Medical sells products like the SCOUT radar localization system, Wrapsody endoprosthesis, and C2 CryoBalloon. It was founded in 1987 in a Murray, Utah industrial park to replace fragile hospital glass syringes with a safer disposable plastic syringe—the name "Merit" reflects its performance-driven culture.

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: -3.04M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
