A maker of continuous glucose monitors that let people with diabetes track their blood sugar in real time without routine fingersticks, with products like the G6, G7, and Stelo. Founded in 1999 in San Diego, the company grew out of research at the University of Wisconsin and launched its first FDA-approved sensor in 2006. Its Stelo was the first continuous glucose monitor cleared for over-the-counter sale in the US, no prescription needed.

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: -12.95M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
