Stoneridge, Inc.
A maker of electrical and electronic systems for vehicles, from commercial trucks and buses to agricultural and off-highway machines. Its products include driver information displays, electronic control units, and MirrorEye, a camera-based system that replaces a truck's side mirrors with screens to cut blind spots and improve aerodynamics. Founded in 1965 in Warren, Ohio, by D.M. Draime, the company began as a small contract shop building wiring harnesses for farm equipment before growing through acquisitions into a global electronics supplier. The name's origin has never been publicly explained, so the story behind "Stoneridge" remains a company mystery.

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 5 years: +19.1K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
