Senseonics Holdings, Inc.
A medical technology company that makes the Eversense line of implantable continuous glucose monitors for people with diabetes. Unlike skin-worn sensors that last days, Eversense's small sensor is placed under the skin of the upper arm by a healthcare professional and can work for up to a year. Founded in 1996 and based in Germantown, Maryland, the company was once called Sensors for Medicine and Science before renaming itself Senseonics in 2012 — a blend of "sense," "eon" (long time), and "-ics" nodding to its long-wear sensors.

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: -582.2K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
