We generate the majority of our revenue from the sale and rental of our portable oxygen concentrator systems and related accessories to patients, third-party payors, home healthcare providers, resellers, and distributors. Our products are marketed in the United States through direct-to-consumer, prescriber, and business-to-business channels, and internationally through distributors and medical equipment providers. Our product offerings include multiple configurations of our Inogen One®, Rove, At Home, and Voxi® systems, in addition to Simeox and Aurora products and related accessories.
Current report
Our strategy is focused on expanding our domestic and international business-to-business channels, improving the productivity of our direct-to-consumer and prescriber sales efforts, and optimizing rental revenue through targeted prescriber engagement.

Expand our domestic home medical equipment, or HME, provider and reseller network. We remain focused on our domestic business-to-business partnerships, including relationships with distributors, key accounts, resellers, our private label collaborator, and traditional HME providers. We offer patient-preferred, low total cost of ownership products to help providers convert their businesses to a non-delivery POC business model.
Previous report
Increase international business-to-business adoption. We continue to believe there is a sizable international market opportunity, particularly in Europe where there is existing oxygen reimbursement for respiratory conditions. In order to take advantage of these international markets, we have partnered with distributors who serve key customers in those markets. We additionally have an Inogen base of operations for sales and customer service in the Netherlands along with sales representatives based in focused European countries, and use a contract manufacturer, Foxconn, located in the Czech Republic to support the majority of our European sales volumes. We are also focused on expanding in the Asia-Pacific region and Latin America where we have added sales representatives to set up new distributors in promising markets.
Previous report
Improve our domestic direct-to-consumer sales and prescriber sales teams and increase productivity. We are continuing to focus on the patient first initiative, which involves cross-training of sales representatives to execute cash sales and insurance rental. Additionally, we expect to continue to focus on increased productivity driven by improved sales management discipline, insights-informed tools, and optimized patient lead generation with a downsized direct-to-consumer sales team.
Previous report
Optimize our rental revenues. We continue to evolve our operating model to focus the enhanced sales teams to drive increased rental revenue by establishing relationships with the prescriber through a consistent cadence of contact.
Previous report
Invest in our respiratory product offerings to develop innovative products and expand clinical evidence. We incurred $4.8 million and $3.5 million in the three months ended September 30, 2025 and 2024, respectively, and $14.1 million and $15.7 million in the nine months ended September 30, 2025 and 2024, respectively, in research and development expenses, and we intend to continue to make similar investments in the foreseeable future.

Previous report
Expand our product offerings and indications for use. We are focused on expanding new products that drive benefits to patients, prescribers and our customers with a clinically relevant pipeline. These products would include innovations that strengthen our offerings in COPD, as well as future innovations that differentiate beyond devices to allow patients and clinicians to better manage respiratory disease with advanced portable oxygen concentrators with digital health value added services, expansion of use to hypercapnia, shortness-of-breath, and to other related disease indications.
Previous report
Our Simeox product is a technology-enabled airway clearance and mucus management device predominantly aimed at serving patients requiring airway clearance, such as those with bronchiectasis – a condition characterized by damaged and widened bronchi that can occur in patients with cystic fibrosis, COPD, or other respiratory conditions. Simeox is used in pulmonary rehabilitation centers as well as at home. Simeox has been cleared under CE mark in the European Union and is currently being sold in Europe and several other markets. In addition, we obtained 510(k) clearance for Simeox in December 2024 and plan to leverage our commercial infrastructure and capabilities to market the device in the United States, while continuing to market it in the other geographies. We intend to commercialize Simeox through the sale or rental of the product initially, followed by recurring sales of device disposables. We began efforts to obtain market feedback, as well as to initialize the work towards reimbursement coverage for the Simeox product in the U.S.
Previous report
In January 2025, we entered into the Collaboration Agreement with Yuwell. The collaboration with Yuwell is expected to broaden our product portfolio through distribution of certain respiratory products, including Yuwell’s stationary oxygen concentrators, in the United States and select other territories, expand and enhance our innovation pipeline through research and development collaboration, and accelerate the entry of our brand into the Chinese market. In the United States, we initiated in June 2025 the launch of the Voxi™ 5, a new stationary oxygen concentrator designed to enhance access to high-quality oxygen therapy for long-term care patients. A more extensive launch of this product is planned in 2026 as we focus on market development. In China, we continue to work through the registration process for our products.

While we have worked to improve our global supply chain, challenges and potential disruptions still exist. We have experienced, and may continue to experience, increases in cost and limited availability of certain raw materials, components, and other inputs necessary to manufacture and distribute our products due to constraints and inflation within the global supply chain, as well as increases in wage costs and the cost and time to distribute our products. Uncertainty around inflationary pressures, interest rates, monetary policy, and changes in tariffs and tax laws could potentially cause new, or exacerbate existing, economic challenges that we may face, including the impact of foreign currency fluctuations on our results of operations, or result in an economic downturn or recession, which could negatively impact our business operations and results. Existing and future potential geopolitical dynamics may create economic, supply chain, energy, and other challenges, including disruptions to business operations, which has impacted, and may in the future negatively impact our business. In particular, international conflicts and disputes could create instability, have and may further result in sanctions, tariffs, and other measures that restrict international trade and may negatively affect our business operations and results.

We may need to raise additional funds to support our investing operations, and such funding may not be available to us on acceptable terms, or at all. If we are unable to raise additional funds when needed, our operations and ability to execute our business strategy could be adversely affected. We may seek to raise additional funds through equity, equity-linked or debt financings. If we raise additional funds through the incurrence of indebtedness, such indebtedness would have rights that are senior to holders of our equity securities and could contain covenants that restrict our operations. Any additional equity financing may be dilutive to our stockholders.
