Funding Propels Oxygen Therapy Leader's Manufacturing and International Growth

SANTA BARBARA, Calif., Feb. 15 /PRNewswire/ -- Inogen, Inc., a leading developer of long-term oxygen therapy technologies, today announced that it has secured $22 million in funding from a group of investors led by Novo A/S. The funds will support new manufacturing capabilities and the company's expansion into international markets.

Denmark-based Novo A/S and Michigan-based Arboretum Ventures are first- time investors in Inogen. Other participants in this round are existing investors Versant Ventures, Avalon Ventures, and Accuitive Medical Ventures.

Heath Lukatch, a partner at Novo who will serve on Inogen's Board of Directors, said, "We believe that Inogen is at the forefront of a paradigm shift in home oxygen therapy. The Inogen One device has the potential to obviate the need for expensive home oxygen tank delivery services, while allowing COPD patients greater flexibility and freedom in their day-to-day lives. We are delighted to be involved with a company that is providing patients with such an innovative device."

Kathy Odell, CEO of Inogen, said, "This latest financing round reflects our investors' confidence in our approach to meeting the needs of a rapidly expanding COPD market," said. "As COPD prevalence escalates, Inogen will further expand its leadership in meeting the needs of patients and the clinical community. Inogen expects to continue its strong momentum by capitalizing on the increased adoption of portable oxygen concentrators and recent changes to Medicare reimbursement."

Inogen's first product, the Inogen One portable oxygen concentrator, has been widely lauded by industry experts as a breakthrough in both technology and design. It was developed to meet the supplemental oxygen needs of those with chronic lung diseases, which affect one in ten individuals aged 45 or more worldwide. The oxygen therapy market is growing at a rate of greater than ten percent annually in the United States.
