Inogen, Inc. INGN

Company Overview

Inogen, Inc. is a U.S.-based medical technology company that develops, manufactures, and markets respiratory care products primarily used to treat chronic respiratory conditions, including chronic obstructive pulmonary disease (COPD). The company operates within the medical devices and home healthcare industries, with a strategic focus on portable oxygen therapy systems designed to improve patient mobility and quality of life. Inogen’s principal revenue drivers include sales and rentals of portable oxygen concentrators (POCs), accessories, replacement parts, and service-related offerings through both direct-to-consumer and business-to-business distribution channels.

The company’s core product portfolio includes lightweight portable oxygen concentrators marketed under the Inogen brand, as well as stationary oxygen concentrators and related respiratory products. Inogen serves patients, home medical equipment providers, distributors, and healthcare systems across multiple regions. A key competitive differentiator is its emphasis on compact, battery-powered oxygen delivery technology that enables ambulatory oxygen therapy outside traditional stationary systems. Founded in 2001 and headquartered in Goleta, California, Inogen evolved from an early-stage medical device innovator into a publicly traded respiratory care company listed on Nasdaq under the ticker INGN.
