Acquisition Expands Inogen's Global Respiratory Care Presence by Addressing the Sizeable, Growing and Underserved Airway Clearance Market Opportunity

Inogen, Inc. (NASDAQ:INGN), a medical technology company offering innovative respiratory products for use in the homecare setting, today announced it has completed the acquisition of Physio-Assist SAS, expanding the company's innovative respiratory portfolio.

Simeox, from Physio-Assist, is a technology-enabled airway clearance and mucus management device predominantly aimed at treating bronchiectasis which is a condition that presents as the lung's bronchi are damaged and widened, in patients with cystic fibrosis or chronic obstructive pulmonary disease. Simeox is used in pulmonary rehabilitation centers, as well as at home.

As a result of the close of the transaction, originally announced on July 13, 2023, Inogen owns Physio-Assist and will now market the Simeox device outside of the United States and continue with ongoing preparations for FDA submission.

"Physio-Assist's Simeox product provides a differentiated and clinically proven innovative airway clearance technology which will add a sizable, growing, and underserved airway clearance market opportunity in support of our strategy to become a multi-portfolio global respiratory care company. Welcoming Physio-Assist to Inogen will add the Simeox airway clearance and mucus management solution to our portfolio and allow us to positively impact patients earlier in their disease journey," said Nabil Shabshab, President and Chief Executive Officer of Inogen. "I am pleased that Inogen can now deliver a broader set of effective solutions, empowering patients to better manage their respiratory conditions in the comfort of their homes while allowing the benefits of ambulation. We are also excited about Simeox's revenue model whereby recurring revenue will be generated by the sale of disposables in addition to the capital sales per device."

Simeox has been cleared under CE mark in the EU and is currently being sold in Europe, Asia, and the Middle East. Inogen will leverage its commercial infrastructure and capabilities to continue marketing the device in these geographies while pursuing US regulatory approvals. The acquisition may provide access to a large and growing market opportunity with 400,000 to 490,000 patients suffering from bronchiectasis in the US eventually.

As previously communicated, the acquisition is expected to be immaterial to Inogen's 2023 revenue and immediately accretive to gross margin. Given the clinical and commercial investment required to obtain FDA clearance and launch Simeox in the US, the transaction is expected to be accretive to adjusted earnings beginning in 2027.
