A vertically integrated maker of specialized electronic systems for security, healthcare, and defense, OSI Systems runs three divisions: Rapiscan and S2 screening gear used at airports and borders, Spacelabs Healthcare patient monitors, and optoelectronic components for original equipment manufacturers. Founded in 1987 as Opto Sensors, Inc., the company's "OSI" name comes from those original initials. A fun quirk: its Rapiscan brand is a portmanteau of "rapid" and "scanner."

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: -84.1K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
