Inogen Inc
A maker of portable oxygen concentrators, Inogen builds lightweight, battery-powered devices like the Inogen One and Rove that pull oxygen straight from the air, freeing people with COPD and other breathing conditions from heavy tanks. The company was founded in 2001 by three University of California, Santa Barbara students who wanted to help co-founder Alison Bauerlein's grandmother, Mae, get around more easily. The name itself blends innovation, oxygen, and generation—a neat nod to what the machines actually do.

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 6 months: -10.8K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
