Item 2.01. Completion of Acquisition or Disposition of Assets.

On September 14, 2023, Inogen, Inc., a Delaware corporation (“Inogen”), completed the acquisition of Physio-Assist SAS, a société par actions simplifiée organized under the laws of France, pursuant to the previously announced Share Purchase Agreement (the “Share Purchase Agreement”) entered into on July 10, 2023 with Mr. Adrien Mithalal, Mr. Jean-Sébastien Lantz, Mrs. Anne Reiser, CAAP Creation, Societe De Capital Risque Provencale Et Corse, Region Sud Investissement, Mérieux Participations 2, Relyens Innovation Santé and certain holders of exercisable securities identified therein (collectively, the “Sellers”). Pursuant to the Share Purchase Agreement, Inogen acquired all of the issued and outstanding capital stock of Physio-Assist SAS. Physio-Assist SAS, directly and through its wholly owned subsidiary, PhysioAssist GmbH, is in the business of the design, production and marketing of medical devices for bronchial decongestion (airway clearance technique) for patients suffering from obstructive respiratory diseases.

Pursuant to the terms of the Share Purchase Agreement, Inogen paid the Sellers approximately $32,000,000 cash at closing subject to adjustment for the estimated net debt amount of Physio-Assist SAS (subject to potential adjustment after closing following confirmation of the actual net debt amount and target working capital amount) and may pay up to either an additional $13,000,000 in cash or $11,000,000 in cash (minus related development costs) depending upon the achievement of one of two alternative milestones related to the Simeox Airway Clearance System’s receipt of FDA de novo authorization or 510(k) clearance within four years of the date of the closing of the transaction.

The foregoing description of the Share Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Share Purchase Agreement. The Share Purchase Agreement was filed as Exhibit 2.1 to Inogen’s Current Report on Form 8-K filed with the Securities and Exchange Commission on July 13, 2023 and is incorporated by reference herein. It is not intended to provide any other factual information about Inogen or Physio-Assist SAS. In particular, the assertions embodied in the representations and warranties contained in the Share Purchase Agreement are qualified by information in confidential disclosure schedules provided by the Sellers to Inogen in connection with the signing of the Share Purchase Agreement. These confidential disclosure schedules contain information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the Share Purchase Agreement. Moreover, certain representations and warranties in the Share Purchase Agreement were used for the purpose of allocating risk between Inogen and Sellers rather than establishing matters as facts. Accordingly, you should not rely on the representations and warranties in the Share Purchase Agreement as characterizations of the actual state of facts about Inogen or Physio-Assist SAS.


Item 7.01. Regulation FD Disclosure.


On September 18, 2023, Inogen issued a press release announcing the completion of the acquisition of Physio-Assist SAS pursuant to the previously announced Share Purchase Agreement. A copy of the press release is furnished herewith as Exhibit 99.1.

Exhibit 99.1




Inogen Completes Acquisition of Physio-Assist

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

GOLETA, Calif., September 18, 2023 – 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.
